Description

Paging method, device and system in network

Technical field

The present invention relates to the field of communication technologies, and in particular, to a paging method, apparatus, and system in a network.

Background technique

In the evolved network developed under 3gpp, the user equipment establishes a wireless connection with the base station through an evolved Evolved Universal Terrestrial Radio Access Network (E-UTRAN) for data transmission. However, if the UE does not perform uplink and downlink data transmission for a long period of time, but maintains a wireless connection with the base station, it will consume more power for the UE, and waste network resources for the network side. . Therefore, generally, when the UE has no data transmission for a period of time, the UE will enter an idle state (IDLE) and disconnect the wireless connection with the base station. However, when the UE enters the idle state, if a message for the UE appears on the network side, the paging flow needs to be triggered to indicate that the UE re-establishes a wireless connection with the base station through the E-UTRAN to receive the report. Text.

The network side generally processes the message for the UE through a gateway such as a Serving Gateway (S-GW) and a Packet Data Network Gateway (P-GW), and performs a paging procedure to re-make the UE and the base station. Establish a connection and receive the message.

However, in order to improve the performance of the gateway, the gateway is separated into two parts according to the functions performed, namely Control Plane and User Plane. The control plane entity of the gateway can be called the control plane gateway (Control). Plane Gateway, GW-C), is mainly used to complete the interface signaling processing function. The forwarding plane entity of the gateway can be called a User Plane Gateway (GW-U), which is mainly used to complete the function of forwarding data. After the UE enters the idle state, if the GW-U receives the packet for the UE, the GW-U needs to perform multiple signaling interactions with the GW-C before the GW-C can send the GW-C to the base station for the UE. The paging message, thereby extending the time for the UE to re-establish a connection with the base station, causing the delay to reduce the user experience. Summary of the invention

In the prior art, when receiving a message for a UE in an idle state, the connection between the UE and the base station needs to be re-established, and the connection between the GW-C and the GW-U is required in establishing a connection. Multiple signaling interactions are performed, which increases the number of interface messages on the forwarding plane and the control plane, which complicates the processing of the forwarding plane and the control plane device, and increases the equipment cost. Moreover, after the control plane is deployed and the forwarding plane is deployed in a distributed manner, after the packet arrives at the forwarding plane, the distributed forwarding plane needs to notify the centralized deployment control plane, causing the message forwarding to be detoured. For example, after the control and forwarding are separated, the control plane device can be deployed in the provincial-level city, and the forwarding plane device can be deployed in the prefecture-level city. In this case, the packet arrival message needs to be returned from the prefecture-level to the provincial-level level, resulting in paging time. The length is changed and the user experience is degraded. For the technical problem, in the embodiment of the present invention, a standard forwarding and control decoupling interface is extended, and the GW-U in the network has in advance the base station established by the GW-C including the base station in the network (evolved The location of the location information of the Node B, eNB) forwards the location information of the eNB related to the location where the UE is located and the paging message to the UE, such that when the GW-U receives the indication for entering the idle state When the packet of the UE is sent, the pre-acquired paging message may be directly sent to the eNB that is related to the location of the UE, and the problem of excessive interface messages caused by the interaction between the paging forwarding plane and the control plane is avoided. Saved the stated

The time when the UE re-establishes the connection with the base station improves the user experience.

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

Embodiment 1

This embodiment describes the technical solution of the present invention from the side of the GW-U in the network. The GW-U includes a location forwarding table, where the location forwarding table includes at least one location set, and the location set includes location information of at least one eNB in the network.

That is, the location forwarding table included in the GW-U may be obtained in a plurality of manners, for example, may be configured to be sent to the GW-U after the GW-C is configured, or may be After the GW-C is configured to be delivered to the GW-U by using other devices, the GW-C may also first establish a location forwarding table having location information of the eNB in the network on the GW-U. The present invention does not limit the manner in which the GW-U obtains the location forwarding table. In this way, when the GW-U sends a paging message to the eNB, the GW-C does not need to additionally provide the location information of the eNB. Each location set in the location forwarding table has a corresponding location set ID, and the location set may correspond to a Tracking Area Identity (TAI) or a Routing Area Identity (TAI), a TAI or a RAI. One or more eNBs are included. Generally, the location set is mainly divided according to the location information of the eNB in the network or the eNB included in a specific area. The forwarding entry in the location forwarding table may be as shown in Table 1:

Table 1

The action set is exemplified by an action set for the base station a. The action set for the base station a may include: setting a destination MAC to be the MAC of the base station a, setting the source MAC to the MAC of the GW-U, and setting the purpose. The IP is the IP address of the base station a, the source IP is set to the IP address of the GW-U, and the port to which the base station a is connected to the GW-U is determined. It should be noted that if the GW-U only performs the encapsulation of the paging message without performing the forwarding process, only the destination IP address needs to be set to the IP address of the base station to meet the requirement, and subsequent forwarding tables may be used, according to the purpose. The IP determines the peer MAC, output port and other information. In addition, the action set may also include other L2 and L3 header field modification actions, such as adding a VLAN identifier, adding an MPLS label, and the like, and is not limited to modifying only the MAC and the IP address, which is not limited by the present invention.

FIG. 1 is a flowchart of a method for paging in a network according to an embodiment of the present invention, where the method includes: S101: When the UE connected to the network enters an idle state, the GW-U acquires an identity of the UE that is sent by the GW-C, an ID of the location set corresponding to an area where the UE is located, and The paging message of the UE.

It should be noted that, when the UE connected to the eNB in the network enters an idle state, the context release message includes an identifier of the UE, and is used to notify the GW-C that the UE enters an idle state, where the GW The ID of the location set corresponding to the area where the UE is located and the paging message for the UE are sent to the GW-U according to the user identifier of the UE. In this way, when the GW-U needs to send a paging message for the UE to the eNB corresponding to the location of the UE, the paging message obtained in advance from the GW-C may be directly used. The signaling interaction with the GW-C when a paging message needs to be sent is eliminated. The paging message sent by the GW-C to the GW-U includes information such as a paging identifier (such as S-TMSI) for the UE and a paging index required for eNB paging, etc. The GW-U does not need to understand the paging message body, but only needs to reserve the paging object as an opaque string. The paging message may also optionally include partial information of the L2 or L3 header (such as source MAC, source IP, etc.).

S102: The GW-U matches the location information of the at least one eNB included in the corresponding location set from the location forwarding table according to the ID of the location set.

That is, taking Table 1 as an example, if the location set ID received by the GW-U is 1, then the location information of the base station a and the base station b that will be matched, if the location received by the GW-U When the set ID is 2, the location information of the base station c, the base station d, and the base station e to be matched will be matched.

S103: The GW-U determines, according to the identity identifier of the UE, whether a packet for the UE is received.

That is, when the UE is in the idle state, the packet is generally not sent out, but other network devices may send packets to the UE in the idle state, and the sent packet includes the UE. The GW-U determines whether there is a packet addressed to the UE by comparing the identity of the destination UE in the matching message with the identity of the UE received from the GW-C.

S104: When the GW-U confirms that the packet for the UE is received, the GW-U sends the identity identifier of the UE to at least one eNB in the matched set of locations, and The paging message.

Taking the entry shown in Table 1 as an example, it is assumed that the location set ID received by the GW-U in S101 is 1, and the location information of the base station a and the base station b are matched, and the GW-U is according to the group entry 1 The two action sets respectively set the destination MAC and the destination IP of the paging message to the addresses of the base station a and the base station b, and send a paging message from the base station a and the base station b connected to the port of the GW-U; The U sends the paging message body in the paging message to the base station a and the base station b respectively, but the destination MAC and the destination IP are the addresses of the base station a and the base station b, respectively. After receiving the paging message, base station a and base station b. And paging the UE according to information such as a user identifier and a paging index in the paging message body.

It can be seen that, between receiving a message for the UE from S103 to sending a paging message to the UE, the signaling interaction between the GW-C and the GW-U does not need to be performed, The GW-U can complete the operation of issuing the paging message according to the information acquired in advance. Therefore, the problem of excessive interface messages caused by the interaction between the paging forwarding plane and the control plane is avoided, which saves the time for the UE to re-establish connection with the base station, and improves the user experience.

It should be noted that the UE in the idle state may also move the location. When the UE moves out of a preset area and enters another area, the GW-C acquires the UE. Location area update information sent by the eNB of the area, where the location area update information includes area information of the changed area of the area where the UE is located. The regions described herein are generally delineated in advance, and the rules of the delineation and the size of the regions are not limited in the present invention. The GW-C determines, based on the embodiment of the location information in the location area update information, that the corresponding location set is re-determined from the location forwarding table, before determining, in S104, that the packet is received for the UE. The GW-U may also update the location information of the matched at least one eNB for the change of the location of the UE. FIG. 2 is a flowchart of a method for updating a region according to an embodiment of the present invention, including:

S201: The GW-U receives the location set ID corresponding to the area where the UE is updated by the GW-C, where the updated area where the UE is located is changed after the area where the UE is in an idle state region.

The ID matches the location information of the at least one eNB included in the corresponding location set from the location forwarding table. That is, before the GW-U receives the packet for the UE, it may receive the location set ID corresponding to the area where the UE is updated by the GW-C, as shown in Table 1, for example. It is said that the location set ID corresponding to the area in which the UE is in the idle state is 1, that is, the area in which the UE is located includes the base station a and the base station b, and the UE may be in one of the base stations. When the UE moves out of the area including the base station a and the base station b, and enters another area, for example, the area includes the base station c, the base station d, and the base station e, and the UE sends the GW to the GW through one of the base stations in the area. Transmitting the location area update information, the location area update information of the GW-C pattern re-determining that the location set ID corresponding to the area where the UE is located is 2, and the GW-U passes the GW-C Updating, re-matching the location forwarding table, determining the base station c, the base station d, and the base station e corresponding to the location set ID, and if the GW-U receives the packet for the UE, the GW -U will send the said to the re-matched base station base station d and base station e Paging message.

After transmitting the paging message to the matched eNB, the GW-U also needs to send the previously received message for the UE to the determined eNB where the UE is located. On the basis of the embodiment shown in FIG. 1, FIG. 3 is a flowchart of a method for sending a packet in a network according to an embodiment of the present invention. As shown in FIG. 3, the method includes:

S301: The GW-U receives the packet forwarding information sent by the GW-C, where the packet forwarding information includes location information of an eNB that sends service request information to the GW-C, where the service request information is The eNB sends the response message of the UE after receiving the paging message to the UE.

S302: The GW-U sends the packet for the UE to the eNB.

That is, after the GW-U sends a paging message to the matched eNB, the eNB performs paging to the UE according to the identity of the UE, and the eNB that receives the response message of the UE Sending the service request information to the GW-C, where the GW-C determines the location information of the eNB that sends the service request information according to the service request information, and sends the information to the GW-U by using the packet forwarding information. In this way, the GW-U can determine, in the signal coverage of the eNB, or which eNB has the best connection environment, and the GW-U forwards the information to the packet. The location information of the eNB carried in the middle sends the message for the UE. Taking Table 1 as an example, for example, the GW-U sends a paging message to the base station a and the base station b, and only the base station a Successfully paging to the UE, that is, receiving the response message of the UE, the base station a sends service request information to the GW-C, and after determining the location information of the base station a, the GW-C goes to the GW. -U transmits message forwarding information carrying the location information of the base station a, and the GW-U transmits the message for the UE to the base station a according to the location information of the base station a.

There is a case in which, after the GW-U sends a paging message, it may happen that the eNB that receives the paging message cannot page the UE, if the GW-U is straight Waiting for and reserving the processing flow for the UE or always buffering the message for the UE will waste the resources of the GW-U and reduce efficiency. Therefore, the embodiment of the present invention provides that the timeout event is determined by timing in the GW-U, and if the packet forwarding information is not obtained from the GW-C, the GW will be sent to the GW. -C sends a paging timeout event message indicating a paging timeout, and the GW-C will instruct the GW-U to discard the message waiting to be sent to the UE. In order to alleviate the processing load of the GW-U. On the basis of the embodiment shown in Figure 1, Figure 4 is a flowchart of a method for determining a paging timeout in a network according to an embodiment of the present invention. As shown in Figure 4, when the GW-U is matched, After the at least one eNB in the set of the location sends the identity identifier of the UE and the paging message, the method includes:

S401: A paging timeout event message sent to the GW-C when the GW-U does not receive the packet forwarding information sent by the GW-C within a predetermined time.

It should be noted that the GW-U shown may start timing after sending the identity identifier of the UE and the paging message to at least one eNB in the matched set of locations, because the GW is shown. -U does not directly receive the service request information returned by the eNB, so the GW-U stops timing only when receiving the message forwarding information for the paging UE from the GW-C, otherwise When the timeout period exceeds the predetermined time, the paging timeout event message sent by the GW-U to the GW-C is used to indicate that the paging UE is timed out.

S402: The GW-U receives the indication of the GW-C to discard the message for the UE. That is, when the GW-C receives the paging timeout event message sent by the GW-U, it determines that the paging UE times out, and indicates that the GW-C is discarded for the UE. The reserved message reduces the unnecessary burden of the GW-U.

It can be seen that the GW-U has a location forwarding table that is established by the GW-C and includes location information of an eNB in the network, and acquires, by the GW-U, when the UE enters an idle state. Determining the identity of the UE, the location information of the eNB related to the location of the UE, and the paging message to the UE, such that when the GW-U receives the message for the UE entering the idle state, The eNB does not need to perform redundant signaling interaction with the GW-C to directly send the pre-acquired paging message to the eNB related to the location where the UE is located, which saves the UE re-establishing the connection with the base station. Time has improved the user experience.

At the same time, the location change of the UE entering the idle state can be updated in time, and the success rate of paging the UE is improved. And adding a judgment on whether the operation of the paging UE is timed out, and discarding the packet corresponding to the timeout paging UE operation, so as to alleviate the processing load of the GW-U. Embodiment 2

In this embodiment, the technical solution of the present invention is described from the side of the GW-C in the network, where the GW-C establishes a location forwarding table on the GW-U or sends the location to the GW-U. The location forwarding table includes at least one location set, where the location set includes location information of at least one base station eNB in the network.

For a description of the location forwarding table that is established on the GW-U and the format and content of the location forwarding table, refer to the related description in the first embodiment, and details are not described herein again.

FIG. 5 is a flowchart of a method for paging in a network according to an embodiment of the present invention, as shown in the following figure:

S501: When the user equipment UE connected to the network enters an idle state, the GW-C receives a UE context release message, where the UE context release message includes an identity identifier of the UE.

S502: The GW-C determines area information of an area where the UE is currently located according to the identity identifier of the UE.

It should be noted that, in the prior art, when a UE is connected to the network, the correspondence between the identity of the UE and the area information of the current area is uploaded to the GW-C. The GW-C determines the area information corresponding to the identity of the UE by comparing the correspondence.

The regions described herein are generally pre-defined, the delineation rules, and the region sizes are not limited in the present invention. S503: The GW-C determines an ID of the corresponding location set from the location forwarding table according to the area information.

Taking Table 1 as an example, if the location set ID received by the GW-U is 1, then the location information of the base station a and the base station b to be matched, if the location set ID received by the GW-U is 2 Then, the location information of the base station c, the base station d, and the base station e to be matched will be matched. The ID of the location set corresponding to the area and the paging message for the UE.

Transmitting, to the GW-U, information necessary for paging the UE in the GW-U, such that when the GW-U receives a message for the UE entering the idle state, it is not required And performing the unnecessary signaling interaction with the GW-C to directly send the pre-acquired paging message to the eNB related to the location where the UE is located.

It should be noted that the UE in the idle state may also move the location. When the UE moves out of a preset area and enters another area, the GW-C acquires the UE. Location area update information sent by the eNB of the area, where the location area update information includes area information of the changed area of the area where the UE is located. On the basis of the embodiment shown in FIG. 5, FIG. 6 is a flowchart of a method for area update according to an embodiment of the present invention, including:

S601: The GW-C acquires location area update information sent by the UE when the area where the UE is in an idle state, where the location area update information includes an area of the changed area of the area where the UE is located. information.

It should be noted that, when the UE in the idle state moves out of the previous area and enters a new area, the UE sends the location area update information by using one of the eNBs currently in the new area. .

S602: The GW-C determines an ID of the corresponding location set from the location forwarding table according to the area information in the location area update information.

S603: The GW-C updates the location set ID corresponding to the area where the UE is located to the GW-U.

And timely updating the location set corresponding to the area information of the area where the UE is located, so that when the GW-U receives the message for the UE, sends the message to the eNB included in the location set. The success rate of sending a paging message received by the UE is higher. For example, the location set ID corresponding to the area where the UE is in the idle state is 1, that is, the area where the UE is located includes the base station a and the base station b, and the UE may be In one of the base stations, when the UE moves out of the area including the base station a and the base station b, and enters another area, for example, the area includes the base station c, the base station d, and the base station e, and the UE passes through some of the areas. a base station sends location area update information to the GW-C, where the location area update information of the GW-C pattern re-determines that the location set ID corresponding to the area where the UE is located is 2, the GW-U Re-matching the location forwarding table by the update of the GW-C, determining the base station c, the base station d, and the base station e corresponding to the location set ID, if the GW-U receives the UE for the UE The message, the GW-U will send the paging message to the re-matched base station c, base station d and base station e.

After receiving the paging message, the eNB may page the UE according to the identity of the UE in the paging message, where the paging may be sent to all UEs within the coverage of the signal range. Paging, only the UE that matches the user ID carried in the paging will choose to receive. After paging to the UE, the UE will return a response message to the eNB that sent the page, and the eNB determines to page the UE after receiving the response message, and will The GW-C sends the service request information of the UE. For the GW-C, optionally, when the GW-C receives the service request information sent by the matched eNB for the UE, The GW-C sends packet forwarding information to the GW-U, where the packet forwarding information includes location information of the eNB that sends the service request information.

There is a case in which, after the GW-U sends a paging message, it may happen that the eNB that receives the paging message cannot page the UE, if the GW-U is straight Waiting for and reserving the processing flow for the UE or always buffering the message for the UE will waste the resources of the GW-U and reduce efficiency. Therefore, the embodiment of the present invention provides that the timeout event is determined by timing in the GW-U, and if the packet forwarding information is not obtained from the GW-C, the GW will be sent to the GW. -C sends a paging timeout event message indicating a paging timeout, and the GW-C will instruct the GW-U to discard the message waiting to be sent to the UE. In order to alleviate the processing load of the GW-U. On the basis of the embodiment shown in FIG. 5, FIG. 7 is a flowchart of a method for determining a paging timeout in a network according to an embodiment of the present invention. As shown in FIG. 7, the method includes:

S701: The GW-C acquires a paging timeout event message sent by the GW-U, where the paging The timeout event message is that the GW-U does not receive the GW-C within a predetermined time after the GW-U sends the identity identifier of the UE and the paging message for the UE to the determined eNB. Sent when the sent message is forwarded.

S702: The GW-C determines, according to the paging timeout event message, that the GW-U fails to page the UE, and instructs the GW-U to discard the packet for the UE.

It should be noted that after the GW-U sends the paging message for the UE, it will start timing for the paging of the UE, that is, by using the GW-U. If the GW-C does not participate in the judgment of the timeout, the GW-C can only determine whether the UE has timed out by the GW-U, thereby further indicating the GW- The next step of U.

In other words, when the GW-U receives the packet forwarding information sent by the GW-C for paging the UE in the predetermined time, the GW-U stops timing and sends the packet to the packet. The eNB information carried in the forwarding information sends the message for the UE. If the UE fails to be paged within a predetermined time, the GW-C will instruct the GW-U to discard the message for the UE.

The description of the GW-C from the description of the GW-U side and the embodiment of the present embodiment will be further described in the following by using two specific application scenarios. A specific application scenario is a case where a message is successfully paged to the UE and a message is sent to the UE; and a second specific application scenario is a case where there is no paging to the UE. The following two specific application scenarios will be described in turn by signaling diagrams.

In the first specific application scenario, refer to FIG. 8, FIG. 8 is a signaling flowchart of paging in a network according to an embodiment of the present invention. As shown in FIG. 8, the method includes:

S801: The GW-C first configures the location forwarding table in the GW-U, assuming that there are two TAIs (that is, two sets of locations), the TAI1 includes the base station a and the base station b, and the TAI2 includes the base station c, the base station d, and the base station e. The details are shown in Table 1.

S802: After the UE enters an idle state, the base station a (assume that the UE is connected before entering the idle state) sends a Context Release message of the UE to the GW-C, indicating that the UE enters a control state. At this time, the GW-C determines that the TAI corresponding to the current area of the user is TAI1.

S803: The GW-C modifies the forwarding entry of the GW-U for the UE, and delivers the IP paging message body. The original GW-U has the following contents of the forwarding entry of the UE:

After sending a message to GW-C, modify it to:

The paging message sent by the GW-C includes information such as the paging identifier (such as S-TMSI) for the user and the paging index required for the paging of the base station. It should be noted that the GW-U does not need to understand the paging message. Body, but keep the paging object as an opaque string. The paging message may also optionally include partial information of the L2 or L3 header (such as source MAC, source IP, etc.). One of the characteristics of this information is that the content of all base stations under the location area is the same.

S804: After the message for the UE arrives at the GW-U, the GW-U matches the forwarding item for the UE, and performs the corresponding action of the forwarding entry, specifically, buffering the received message.

S805: The GW-U starts a timer (for paging non-response processing), takes out the stored paging message, and sends the paging message to two base stations in the corresponding TAI1, respectively, and respectively uses the destination MAC address of the paging message. The destination IP is set to the addresses of the base station a and the base station b, and the paging message is transmitted from the port where the base station a and the base station b are connected to the GW-U. After receiving the paging message, base station a and base station b. Paging the UE according to a user identifier corresponding to the paging message.

S806: In this embodiment, it is assumed that the base station a finally successfully pages the UE, that is, the base station a receives the response message returned by the UE, and the base station a sends the response message to the GW-C. Send a service request message.

S807: After receiving the service request information, the GW-C sends the packet forwarding information to the GW-U, where the packet forwarding information includes the location information of the eNB that sends the service request information. Reduce the storage burden on the GW-U.

S808: After receiving the update IP processing table message, the GW-U stops the timer, and extracts the buffered message, and sends the packet to the base station a where the UE is located, and is further forwarded by the base station a to the UE. In the second specific application scenario, refer to FIG. 9, FIG. 9 is a signaling flowchart of paging in a network according to an embodiment of the present invention. As shown in FIG. 9, the method includes:

S901: The GW-C configures a location forwarding table in the GW-U, where the location set included in the location forwarding table is the same as that in Table 1. However, in order to facilitate drawing, the TAI2 includes only one base station c in the embodiment shown in FIG. And setting the location of the UE corresponding to two location sets, respectively TAI1 and TAI2, optionally, in some implementation scenarios, TAI1 and TAI2 may also be combined into one TAI list, assuming that the location binding ID of the TAI list is 3. The action set includes location information of the base station a included in the action set of the original TAI1 and TAI2, location information of the base station b, and location information of the base station c. The forwarding entry corresponding to the TAI list may be in the format in Table 2:

Table 2

S902: After the UE enters the idle state, the base station a (assumed to be the base station connected before the UE enters the idle state) sends the UE context release message to the GW-C, indicating that the UE enters the control state. At this time, the GW-C determines that the TAI corresponding to the current area of the user is a TAI list.

S903: The content of the forwarding entry of the GW-C for the UE is similar to that of the S803, and is not described here. The paging message sent by the GW-C includes information such as the paging identifier (such as S-TMSI) for the user and the paging index required for the paging of the base station. It should be noted that the GW-U does not need to understand the paging message. Body, but keep the paging object as an opaque string. The paging message may also optionally include partial information of the L2 or L3 header (such as source MAC, source IP, etc.). One of the characteristics of this information is that the content of all base stations under the location area is the same.

S904: After the packet for the UE arrives at the GW-U, the GW-U matches the forwarding entry that is the UE, and performs the corresponding action of the forwarding entry, specifically, the received packet. And determining a base station for sending a paging message.

S905: The GW-U starts a timer (for paging non-response processing), takes out the stored paging message, and sends the paging message to the two base stations in the corresponding TAI1, respectively, and respectively uses the destination MAC address of the paging message. The destination IP is set to the addresses of the base station a and the base station b, and the paging message is transmitted from the base station a, the base station b, and the port connected to the GW-U by the base station c. The base station a, the base station b, and the base station c receive the paging message. And paging the UE according to the user identifier corresponding to the paging message. In the embodiment shown in FIG. 9, it is assumed that the UE is not successfully paged, so that the base station a, the base station b, and the base station c do not receive the response message returned by the UE.

S906: The GW-U times out and does not receive the packet forwarding information sent by the GW-C, and the GW-U sends a paging timeout event message to the GW-C.

S907: After receiving the paging timeout event packet, the GW-C determines that the GW-U fails to page the UE, and instructs the GW-U to discard the packet for the UE.

It can be seen that the GW-U has a location forwarding table that is established by the GW-C and includes location information of an eNB in the network, and acquires the information that is sent by the GW-U when the UE enters an idle state. The identity of the UE, the location information of the eNB related to the location of the UE, and the paging message to the UE, such that when the GW-U receives the message for the UE entering the idle state, The eNB does not need to perform redundant signaling interaction with the GW-C to directly send the pre-acquired paging message to the eNB related to the location of the UE, which saves the time for the UE to re-establish the connection with the base station. , to improve the user experience.
