Description

A kind of method and system and the network equipment thereof of network control shunting

Technical field

The present invention relates to communication technical field, relate in particular to a kind of method and system and network equipment thereof of network control shunting.

Background technology

Along with the growth to radio communication service demand, increasing cordless communication network has stepped into or has stepped into the practical stage, comprise: widely used global system for mobile communications (GSM, Global System for Mobile communications), General Packet Radio System (GPRS, General Packet Radio System), Universal Mobile Telecommunications System (UMTS, Universal Mobile Telecommunications System), and stepping into the long evolving system (LTE of commercial stage, Long Term Evolution) etc. network system.Along with popularizing of intelligent terminal, the surge of people to data communication need, causes the load of the cellular network including said system increasing.

In WLAN (wireless local area network) (WLAN, Wireless Local Area Network), terminal connects by WIFI module (Wireless Fidelity) and WAP (wireless access point) (AP, Access point), thereby obtains corresponding communication service; WAP (wireless access point) can access the core net of above-mentioned Cellular Networks system, also can be directly connected to internet (Internet)---and the business that is terminal does not need the core net through Cellular Networks system; Conventionally this data routing mode that is directly connected to internet is called to local forward (Local breakout); By using WLAN (wireless local area network) to terminal carrying out service data distribution, the partial data on cellular network is diverted in WLAN (wireless local area network) and is transmitted, can reduce the load of Cellular Networks system, optimize the business datum Route Selection of terminal, promote user and experience.The fusion of cellular system and WLAN (wireless local area network) becomes the trend of the network capacity extension and the networking of vast cellular carrier.

What be widely used now is the WLAN (wireless local area network) shunting based on subscriber equipment (UE, User Equipment), and subscriber equipment determines which business transmits in WLAN (wireless local area network), and which business is transmitted at cellular network.Due to subscriber equipment---there is larger randomness in the shunting decision-making that is terminal, shunting effect is uncontrollable.For the shunting of control terminal, can carry out by Network finding and selection function (ANDSF, Access Network Discovery and Selection Function) shunting of guiding terminal.Network side issues distributing strategy to terminal, and terminal arrives suitable Internet Transmission according to distributing strategy by corresponding service distributing.Distributing strategy is the shunting of guiding terminal to a certain extent, but due to time variation and the diversity of wireless environment, only relies on the shunting effect of distributing strategy to promote more limited.

With respect to terminal, the state of wireless access network (RAN, Radio Access Network) to eat dishes without rice or wine link-quality and network solve more comprehensively, can be a better shunting decision point.In cellular network, utilize carrying to transmit the business of different service quality (QoS, Quality of service), business identical quality of service requirement or that type is identical is placed in same carrying and is transmitted.Taking LTE network as example, evolved packet system bearing identification for carrying from terminal to packet data gateway (EPS Bearer Identity) identifies, the network element of LTE Access Network---enode b (Evolved Node B, eNB) distribute one and evolved packet system bearing identification radio bearer mark (Radio Bearer ID) one to one, and according to the interface-free resources of the corresponding radio bearer mark of quality of service configuration corresponding to evolved packet system bearing identification, realize the guarantee of the service quality end to end from network to terminal.But in LTE network, enode b can only be known the service quality that carrying is corresponding, and the concrete business of nonrecognition, do not know the relevant information of shunting of business, may cause shunting decision-making and the conflict of business routing property of enode b, for example some operators business on one's own account, although quality of service requirement is not high, but this business only provides service by cellular core network, and a lot of WLAN (wireless local area network) is directly local forwarding in the network system of prior art, without cellular core network, therefore, even if the transmission of eating dishes without rice or wine of WLAN (wireless local area network) can meet the service quality of this business, the carrying under this business should be switched to WLAN (wireless local area network) transmission yet, otherwise will cause service disconnection, affecting user experiences.
