FIG. 1 is a schematic flowchart of Embodiment 1 of a method for selecting a wireless local area network according to the present invention. The executive body of the method embodiment may be a WWAN base station. The method of the embodiment of the present invention is to perform the policy management for the UE to search for the WLAN AP during the mobile process, so that the UE does not have to perform unnecessary scanning of the WLAN AP (for example, the non-operator WLAN AP). The method specifically includes the following steps:

S101: Receive WLAN selection policy information configured by the Operations Administration Maintenance (OAM).

The method provided by the embodiment of the present invention can be applied to a heterogeneous network composed of a WWAN base station, an operator WLAN AP, and a non-operator WLAN AP, and the cell covered by the WWAN base station is the current serving cell of the UE, and the operator WLAN AP and the non- The coverage of the operator's WLAN AP is within the coverage of the WWAN base station.

Specifically, the OAM is a system for managing WWAN network devices and WLAN network devices. The WWAN network devices and the WLAN network devices may share or have a set of OAMs respectively. The WWAN network devices may be different WWAN base stations, and the WLAN network devices may be WLAN APs. That is, in the embodiment of the present invention, the OAM can be regarded as a management system of the upper layer of the WWAN and the WLAN network device. The OAM configures the WLAN selection policy information to the WW AN base station, where the WLAN selection policy information may be information reflecting the location of the WLAN AP of the operator, or may be information reflecting the data performance of the user under the WLAN AP of the operator, or may be other The information about the policy management of the UE scanning the WLAN AP (including the carrier WLAN AP and the non-operator WLAN AP) is implemented in the embodiment of the present invention.

S102: Determine, according to the WLAN selection policy information, whether to instruct the UE to perform at least one carrier WLAN AP search selection; if yes, instruct the UE to perform at least one carrier WLAN AP search selection; if not, instruct the UE not to perform the operator WLAN AP search The carrier WLAN AP search selection includes an operator WLAN AP search, or an operator WLAN AP search and an operator WLAN AP selection access.

Specifically, the WW AN base station determines, according to the WLAN selection policy information of the OAM configuration, whether to instruct the UE to perform the WLAN AP search selection, and if yes, instructs the UE to perform at least one carrier WLAN AP search selection; if not, instructs the UE not to perform The WLAN AP search selection is performed by the UE; and the WLAN AP search selection performed by the UE includes the UE's search for the WLAN AP of the operator, or may also include the selected access of the WLAN AP after the UE searches for the WLAN AP of the operator. Here is a simple example: It is assumed that the UE is always in the mobile state and the WWAN base station can know the location of the UE (for example, using the location report of the UE), when the UE moves to a certain location (the location also has a WLAN AP deployed) The WW AN base station determines whether the location is within the coverage of the operator's WLAN AP according to the pre-configured WLAN policy selection information; if not, the WLAN AP to which the location belongs is a non-operator WLAN AP, and the WWAN base station Instructing the UE not to perform any search selection of the WLAN AP, that is, instructing the UE not to enable the Wi-Fi selection function; if yes, instructing the UE to open the Wi-Fi selection function, searching for the operator WLAN AP, and then determining whether to access the operator WLAN APo

Due to the large number of applications of WLAN (free band and freely installed), there are a large number of non-operator APs in the network, for example, APs set up by individuals or other non-operator organizations, which do not provide non-operational seamless roaming of UEs. It is unnecessary for the AP to be scanned by the eNB to waste the power and performance of the UE. Therefore, the WLAN selection policy information in the above example can be used to control the number of times the UE scans the WLAN AP, so that the UE does not have to scan all WLAN APs at all times. Non-operator WLAN AP) saves the power of the UE. The wireless local area network selection method provided by the embodiment of the present invention receives the WLAN selection policy information configured by the OAM, and determines whether to instruct the UE to perform at least one WLAN AP search selection according to the WLAN selection policy information, that is, implements wireless local area network selection for the heterogeneous network. Policy management is implemented to prevent the UE from continuously scanning unnecessary WLAN APs, thereby greatly reducing the power consumption of the UE.

On the basis of the foregoing embodiment shown in FIG. 1 , the WLAN selection policy information may include location information of the WLAN AP of the operator, coverage information of the WLAN AP and the WWAN base station, and load performance statistics of the WLAN AP of the operator. The discriminating threshold, the load performance discriminating threshold of the WWAN base station, the information of the UE, and the WWAN base station instructing the UE to search for at least one of the detection frequencies of the operator WLAN AP.

Specifically, the WLAN selection policy information may be one or any combination of the foregoing multiple types of information. When the content included in the WLAN selection policy information is different, the method provided by the embodiment of the present invention may be different. The technology of the present invention is to manage the WLAN AP of the UE. The embodiment of the present invention can be implemented in various manners. Here, five implementation manners are listed, but the five implementation manners are only the methods involved in the embodiments of the present invention. For a simple example, the implementation manner of the embodiment of the present invention is not limited thereto.

As a first possible implementation manner of the embodiment of the present invention, it is assumed that the content of the OAM configuration policy information for the WWAN base station includes only the load performance statistics discriminating threshold of the operator WLAN AP; optionally, the load of the operator WLAN AP The performance statistics discriminating threshold may include at least one of an operator WLAN AP cable end data rate threshold, a current access user number threshold of the operator WLAN AP, and an average rate threshold of the current access user of the operator WLAN AP. Take the current number of access users of the WLAN AP of the carrier as an example: The current serving cell of the UE is the cell under the coverage of the WWAN base station. When the WWAN base station learns that the number of users accessing the WLAN AP of the current operator has exceeded the current WLAN AP of the carrier. After the number of users enters the threshold, the WWAN base station instructs the UE to continue to connect to the WWAN serving cell, and does not perform the carrier WLAN AP search selection to ensure better user data performance; when the WWAN base station learns the number of users currently accessing the operator WLAN AP If the threshold of the current number of access users of the WLAN AP of the operator is not exceeded, the WWAN base station instructs the UE to perform the WLAN AP search selection of the operator.

As a second feasible implementation manner of the embodiment of the present invention, it is assumed that the OAM configuration is given to The content of the WWAN base station's policy information includes only the load performance determination threshold of the WWAN base station. Optionally, the load performance determination threshold of the WWAN base station includes the current access user threshold of the WWAN base station, and the average access user average of the WWAN base station. At least one of a data throughput threshold, a current active number of users of the WWAN base station, and an average data throughput threshold of a currently active user of the WWAN base station. Taking the average data throughput rate of the current access user of the WWAN base station as an example, when the WWAN base station learns that the current data performance of the UE is lower than the average data throughput threshold of the current access user of the WWAN base station, the UE is instructed to perform the WLAN AP search selection. In order to enable the UE to obtain better user data performance; when the WWAN base station learns that the current data performance of the UE is higher than the average data throughput threshold of the current access user of the WWAN base station, the UE is instructed to continue to connect to the WWAN serving cell, and does not perform Carrier WLAN AP search options to ensure good user data performance.

As a third possible implementation manner of the embodiment of the present invention, it is assumed that the content of the policy information of the OAM configured to the WWAN base station includes only information of the UE. Optionally, the information of the foregoing UE includes the moving speed of the UE (high speed or medium speed). At least one of the UE type (gold or normal or low priority), the UE's service type (real-time or non-real-time), and the UE's service priority (different quality of service). Taking the moving speed of the UE as an example, if the UE is in a high-speed mobile state, because the coverage of the WLAN AP of the operator is small, the WWAN base station instructs the UE to continue to connect to the WWAN serving cell without performing the carrier WLAN AP search selection.

As a fourth feasible implementation manner of the embodiment of the present invention, it is assumed that the OAM configuration is given to

The information in the policy information of the WWAN base station is the coverage relationship information between the WLAN AP and the WWAN base station. The coverage relationship information between the WLAN AP and the WWAN base station is a neighboring relationship. The coverage of the WLAN AP of the operator is often within the coverage of the WWAN base station. The neighboring area information of the WWAN base station and the WLAN AP of the operator needs to be added to each other.

The detection frequency of the WLAN AP, that is, the WWAN base station instructs the UE to perform the operator WLAN AP search selection at intervals, or when the UE has a new data service, instructs the UE to perform the carrier WLAN AP search selection, the purpose is also to avoid the existing In the technology, the UE continuously performs carrier WLAN AP search selection.

A method for selecting a wireless local area network according to an embodiment of the present invention, by receiving an OAM configuration

The WLAN selects the policy information, and the WLAN selection policy information includes different information that can be used to select the operator WLAN AP for policy management. The WWAN base station determines, according to the WLAN selection policy information, whether to instruct the UE to perform the operator WLAN AP search selection, that is, The policy management of the wireless local area network selection of the heterogeneous network is implemented to prevent the UE from continuously scanning unnecessary WLAN APs, thereby greatly reducing the power consumption of the UE.

2 is a schematic flowchart of Embodiment 2 of a method for selecting a wireless local area network according to the present invention, and FIG. 3 is a schematic diagram of a scenario 1 of a method for selecting a wireless local area network according to the present invention. The WLAN AP of the carrier in the embodiment of the present invention is the first carrier. For the WLAN AP, the WLAN selection policy information includes location information of the first carrier WLAN AP, a load performance statistical determination threshold of the first carrier WLAN AP, a load performance determination threshold of the WWAN base station, and information of the UE. The executor of the embodiment of the present invention is a WWAN base station; specifically, the method includes the following steps:

S201: Receive WLAN selection policy information configured by the OAM.

Specifically, the OAM is a system for managing WWAN network devices and WLAN network devices. The WWAN network devices and the WLAN network devices may share or have a set of OAMs respectively. The WWAN network devices may be different WWAN base stations, and the WLAN network devices may be WLAN APs. That is, in the embodiment of the present invention, the OAM can be regarded as a management system of the upper layer of the WWAN and the WLAN network device.

The OAM configures the WLAN selection policy information to the WWAN base station, where the WLAN selection policy information includes location information of the first carrier WLAN AP, a load performance statistical determination threshold of the first carrier WLAN AP, a load performance determination threshold of the WWAN base station, and a UE information.

S202: The UE moves to the first location, and determines, according to the location information of the first carrier WLAN AP, whether the first location is within the coverage of the first operator WLAN AP; if not, executing S203; if yes, executing S204. S203: Instruct the UE not to perform any WLAN AP search selection, and end the process.

Specifically, as shown in FIG. 3, when the UE moves from the A location to the first location (B location), the WW AN base station determines, according to the configured location information of the first carrier WLAN AP, that the first location is not in the first carrier WLAN. Within the coverage of the AP, the WLAN AP X that belongs to the first location is a non-operator WLAN AP, and the WWAN base station indicates that the UE does not perform any WLAN AP search selection, where any WLAN AP search selection includes the operator WLAN AP search. Select and non-operator WLAN AP search options.

S204: Instruct the UE to search for the first carrier WLAN AP, and determine whether the UE is instructed to access the first carrier WLAN APo according to the load performance statistical discriminating threshold of the first operator WLAN AP, the load performance discriminating threshold of the WWAN base station, and the information of the UE.

If the UE moves from the first location (B location) to the first location (C location), the WWAN base station determines, according to the configured location information of the first carrier WLAN AP, that the C location belongs to the coverage of the first carrier WLAN AP. The WWAN base station instructs the UE to search for the first operator WLAN AP; and then determines whether the UE is instructed to access the first operation according to the load performance statistical discriminating threshold of the first operator WLAN AP, the load performance discriminating threshold of the WWAN base station, and the information of the UE. WLAN AP, specifically:

Determining, according to the load performance statistical discriminating threshold of the first carrier WLAN AP, the load performance discriminating threshold of the WWAN base station, and the information of the UE, whether the data performance of the UE accessing the first operator WLAN AP is better than the coverage of the UE by the WWAN base station. If the network is in the next step, the UE is instructed to access the first carrier WLAN AP; if not, the UE is not allowed to access the first carrier WLAN AP. For example, after the WWAN base station instructs the UE to search for the first carrier WLAN AP, comprehensively consider the current number of access users of the WWAN base station, the current number of access users of the first operator WLAN AP, and the moving speed of the UE under the coverage of the WWAN base station, After the current WWAN base station covers the data service priority of the UE, it is determined that the UE obtains better data performance after accessing the first operator WLAN AP, and then allows the UE to access the first operator WLAN AP; if the WWAN base station comprehensively considers At this time, the data access performance of the UE covered by the WWAN base station is better than the data performance of the UE accessing the WLAN AP of the first carrier, and the UE is instructed to continue to perform data services within the coverage of the WWAN base station without accessing the first carrier WLAN APo. When the UE moves from the first location (C location) to the first location (D location), the WWAN base station still determines that the D location remains according to the configured location information of the first carrier WLAN AP. The WW AN base station determines whether the UE is connected to the first carrier WLAN AP according to whether the UE is connected to the first carrier WLAN AP. If the UE is connected to the first operator WLAN AP, the WWAN base station is based on the first The load performance statistical discriminating threshold of the operator WLAN AP, the load performance discriminating threshold of the WWAN base station, and the information of the UE determine whether the data performance of the UE accessing the first operator WLAN AP is better than the data performance of the UE under the coverage of the WWAN base station; If yes, the UE is instructed to continue to connect to the first operator WLAN AP; if not, the UE is instructed to disconnect from the current first carrier WLAN AP Y and reconnect to the WWAN base station for data service.

When the UE moves to the E location, the UE is not in the coverage of the first carrier WLAN AP. Therefore, according to the pre-configured WLAN selection policy information, the UE does not perform the selection of the first carrier WLAN AP. The service only needs to maintain a connection with the WWAN base station.

It should be noted that the B position, the C position, and the D position are all the first positions (but all of the three positions are different positions in the first position), and the B position is not in the coverage of the first operator WLAN AP. Both the C location and the D location are within the coverage of the first carrier WLAN AP.

The method for selecting a WLAN according to the embodiment of the present invention, by receiving the WLAN selection policy information configured by the OAM, and determining, according to the WLAN selection policy information, whether the UE is instructing the UE to perform the WLAN AP search selection by using the WLAN selection policy, that is, implementing the heterogeneous network The WLAN is selected for policy management to prevent the UE from continuously scanning unnecessary WLAN APs, thereby greatly reducing the power consumption of the UE. At the same time, the UE can seamlessly switch between the WWAN and the WLAN without manual intervention by the user. The operation improves the user experience. In addition, whether the UE performs the selection after accessing the first carrier WLAN AP to access the first carrier WLAN AP also ensures the communication performance of the UE accessing the operator WLAN AP.

4 is a schematic flowchart of Embodiment 3 of a method for selecting a wireless local area network according to the present invention. FIG. 5 is a schematic diagram of a second application scenario of a method for selecting a wireless local area network according to an embodiment of the present invention.

During the UE's movement, the UE's current The serving cell may switch from the current serving macro base station cell to another WWAN micro base station cell, that is, the current serving base station is switched from the WWAN macro base station to another WWAN micro base station, and may also be switched by the WWAN micro base station to the WWAN macro base station, that is, the current The serving base station then switches back from the WWAN micro base station back to the WWAN macro base station. Therefore, the UE currently serving the WWAN base station in this embodiment may be the WWAN macro base station or the WWAN micro base station in FIG. 5. Specifically, the method includes the following steps:

S401: Receive WLAN selection policy information of the OAM configuration.

S403: Instruct the UE not to perform any WLAN AP search selection, and end the process.

Specifically, as shown in FIG. 5, when the UE moves from the A location to the first location (B location), the WWAN base station (in this case, the currently served WWAN macro base station) according to the configured location information of the first carrier WLAN AP If the first location is not within the coverage of the first carrier WLAN AP, the WLAN AP X that belongs to the first location is a non-operator WLAN AP, and the WWAN base station indicates that the UE does not perform any WLAN AP search selection, any of the The WLAN AP search selection includes the operator WLAN AP search selection and the non-operator WLAN AP search selection.

S404: Instruct the UE to search for the first carrier WLAN AP, and determine a threshold according to the load performance of the first carrier WLAN AP, a load performance determination threshold of the WWAN base station, and the UE. The information determines whether the UE is instructed to access the first carrier WLAN APo.

Determining, according to the load performance statistical discriminating threshold of the first carrier WLAN AP, the load performance discriminating threshold of the WWAN base station, and the information of the UE, whether the data performance of the UE accessing the first operator WLAN AP is better than the coverage of the UE by the WWAN base station. If the network is in the next step, the UE is instructed to access the first carrier WLAN AP; if not, the UE is not allowed to access the first carrier WLAN AP. For example, after the WWAN base station instructs the UE to search for the first carrier WLAN AP, comprehensively consider the current number of access users of the WWAN base station, the current number of access users of the first operator WLAN AP, and the moving speed of the UE under the coverage of the WWAN base station, After the current WWAN base station covers the data service priority of the UE, it is determined that the UE obtains better data performance after accessing the first operator WLAN AP, and then allows the UE to access the first operator WLAN AP; if the WWAN base station comprehensively considers At this time, the data access performance of the UE covered by the WWAN base station is better than the data performance of the UE accessing the WLAN AP of the first carrier, and the UE is instructed to continue to perform data services within the coverage of the WWAN base station without accessing the first carrier WLAN APo. S405: According to location information of the first carrier WLAN AP and the second carrier WLAN

The location information of the AP determines that the second location is located in the common coverage area of the first carrier WLAN AP and the second carrier WLAN AP, and indicates that the UE searches for the first carrier WLAN AP and the second carrier WLAN AP.

Specifically, the UE moves from the first location (C location) to the second location (F location), and the currently served WWAN base station (which may be a WWAN macro base station or a WWAN micro base station at this time) according to the first carrier WLAN AP The location information and the location information of the second carrier WLAN AP determine that the second location is in the common coverage area of the first carrier WLAN AP and the second carrier WLAN AP, and the WWAN base station instructs the UE to search for the first carrier WLAN. AP and second carrier WLAN AP. At this time, it should be noted that if the UE does not access the first operator WLAN AP in step S404, the WWAN base station indicates the UE search. The first carrier WLAN AP and the second carrier WLAN AP; if the UE has accessed the first carrier WLAN AP in step S404, the WWAN base station instructs the UE to search for the second operator WLAN AP.

S407: Instruct the UE to access the second carrier WLAN AP.

S408: Instruct the UE not to access the second carrier WLAN AP.

If yes, the WWAN base station instructs the UE to access the second operator WLAN AP; otherwise, the WWAN base station indicates that the UE does not access the second operator WLAN APo, for example: if the UE has currently selected to connect to the first operator WLAN AP, and After determining the current number of access users of the WWAN base station, the first carrier WLAN AP, and the second carrier WLAN AP, and the moving speed of the UE under the WWAN base station coverage, and the data service priority of the UE under the coverage of the WWAN base station, determining the access first After the WLAN AP of the carrier still obtains better data performance, the WWAN base station instructs the UE to continue to maintain the connection with the first operator WLAN AP; for example: if the UE is currently connected to the first carrier WLAN AP, and Considering the data access performance of the WWAN base station, the data access performance of the first carrier WLAN AP, and the first carrier WLAN AP at this time, if the WWAN base station determines that accessing the second operator WLAN AP can obtain better data performance, Then, the UE is instructed to disconnect the current connection with the first operator WLAN AP and connect to the second operator WLAN AP for data service. For another example: if the UE currently selects to connect to the current serving WWAN base station, and comprehensively considers the current number of access users of the WWAN base station, the first carrier WLAN AP, and the second carrier WLAN AP, and the UE of the WWAN base station coverage After the mobile speed and the WW AN base station cover the data service priority of the UE, it is determined that the access to the current serving WW AN base station still obtains better data performance, and the WWAN base station instructs the UE to continue to maintain the connection with the current serving WW AN base station.

When the UE moves further to the E location, the UE is not in the coverage of the first carrier WLAN AP and the second carrier WLAN AP, so the UE does not perform the WLAN AP according to the pre-configured WLAN selection policy information. For the search option, the data service only needs to be connected to the WW AN base station (macro base station or micro base station).
