Embodiment

For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.

The first data distribution method flow chart that Fig. 1 provides for the embodiment of the present invention.As shown in Figure 1, the data distribution method that the present embodiment provides specifically can be applied to be provided with the processing procedure of the service data in communication system shunting of Wireless Fidelity (Wireless Fidelity is called for short WIFI) network.This communication system is specifically as follows Long Term Evolution (Long Term Evolution is called for short LTE) communication system, universal mobile telecommunications system (Universal Mobile Telecommunications System is called for short UMTS) communication system etc.LTE communication system specifically comprises grouped data network gateway (Packet Data Network Gateway, abbreviation P-GW), gateway (Service Gateway, abbreviation S-GW), Mobility Management Entity (Mobility Management Entity, abbreviation MME), base station (E-UTRAN Node B, be called for short eNB) and WIFI network (set up by access point Access Point, access point is called for short AP).UMTS communication system specifically comprises Gateway GPRS Support Node (Gateway GPRS Support Node, abbreviation GGSN), GPRS serving GPRS support node (Serving GPRS Support Node, abbreviation SGSN), base station node B, radio network controller (Radio Network Controller is called for short RNC) and WIFI network.

The data distribution method that the present embodiment provides specifically comprises:

Steps A 10, user equipment (UE) receive the shunting instruction that network equipment sends, and wherein, described shunting instruction is radio resource control RRC message;

Steps A 20, described UE access WIFI network carry out transfer of data.

Particularly, in LTE communication system, eNB can realize network equipment, and in UMTS communication system, Node B and RNC can coordinate and realize network equipment, and certainly, in other communication systems, network equipment can adopt the network element of similar functions to realize.

UE receives the shunting instruction (WIFI Offload Request) that network equipment sends, the functional module that this shunting instruction is opened WIFI specifically for indication UE, this shunting instruction can, for WIFI shunting request (WIFI Offload Request), can be also WIFI module open command.When this shunting instruction is WIFI shunting request, UE can judge whether to accept WIFI shunting, if accept, by accepting WIFI shunting, determines to report.When this shunting instruction is WIFI module open command, UE directly opens WIFI module according to this WIFI module open command.This shunting instruction is RRC message, and this shunting instruction can be the RRC message redefining, and also can for example, increase a field in existing RRC message for carrying this shunting instruction by existing RRC message, represents shunting instruction.UE access WIFI network can also carry out the mutual authentication of UE and WIFI network in access procedure.UE can or send upstream data by WIFI network downlink data receiving.

Shunting node is specifically as follows this network equipment, can be also the data gateway in communication system.When network equipment is shunting node, WIFI network settings are between this network equipment and UE, data gateway can first send to network equipment by downlink data, network equipment sends to UE by downlink data by WIFI network again, UE also can first send to network equipment by upstream data by WIFI network, and network equipment sends to data gateway by upstream data again.When data gateway is shunting node, WIFI network settings are between this data gateway and UE, and data gateway sends to UE by downlink data by WIFI network, and UE also can directly send to data gateway by WIFI network by upstream data.

In actual applications, when UE electric weight is not enough, or the distributing strategy of UE do not support shunting, or UE does not find suitable WIFI network while carrying out the scanning of WIFI network, UE can refuse WIFI shunting, and this refusal WIFI shunting decision and reason for rejection are reported to network equipment.When UE refusal WIFI shunting, can realize the mutual of UE and network equipment according to the handling process of prior art, do not repeat them here.

The data distribution method that the present embodiment provides, UE receives the shunting instruction that network equipment sends, and wherein, shunting instruction is radio resource control RRC message, and access WIFI network carries out transfer of data.UE selects WIFI network insertion according to the shunting instruction receiving, and has realized business datum shunting.And UE can give tacit consent to WIFI module is closed, and opens WIFI module under the request of network equipment equipment again, has saved energy consumption.

In actual applications, UE may be in different states, and the situation of the data distribution method flow process that triggering the present embodiment provides also can be for multiple, for the implementation possibility difference of different application scenarioss.For different application scenarioss, the present embodiment is elaborated below.

In the present embodiment, described UE is in idle condition; Correspondingly, steps A 10, described user equipment (UE) receives the shunting instruction that network equipment sends, and specifically comprises:

Described UE receives the RRC beep-page message that described network equipment sends, and wherein, carries described shunting instruction in described RRC beep-page message.

If UE reports and accepts WIFI shunting decision to network equipment, steps A 20, and described UE accesses described WIFI network and carries out transfer of data, specifically can comprise:

Described UE sends to carry to described network equipment and accepts the RRC connection request message that WIFI shunting determines, or send and carry the administrative messag of accepting WIFI shunting decision to described network equipment by described WIFI network, so that described network equipment determines downlink data to send to described UE by described WIFI network according to the described WIFI of acceptance shunting, receive the downlink data that described WIFI network sends.

Particularly, when the downlink data of UE arrives data gateway, data gateway routes to gateway by downlink data, and when UE is during in idle condition, gateway need to wake UE up.When receiving the downlink data issuing to UE from data gateway, gateway carries out buffer memory by this downlink data, and sends GTP-C downlink data notification message to network management entity.In this GTP-C downlink data notification message, can carry data context (Data Context) information of downlink data, data context information can comprise the information such as QoS grade identifier (QoS Class Identifier is called for short QCI), type of service.Carry and accept the administrative messag that WIFI shunting determines and can be, but not limited to association request frame.In LTE communication system, P-GW can realize data gateway, S-GW can realize gateway, and MME can realize network management entity, in UMTS communication system, GGSN can realize gateway, SGSN can realize network management entity, and SGSN can also realize the function of gateway, certainly, in other communication systems, network management entity can adopt the network element of similar functions to realize.
