Wherein, 3GPP Access Network is comprised of evolution base station (Evolved NodeB, referred to as eNB), and it is mainly responsible for the transmitting-receiving of wireless signal, contacts Radio Resource, scheduling of resource and the access control of management air interface by air interface and terminal.
Core net, comprised home subscriber server (Home Subscriber Server, referred to as HSS), Mobility Management Entity (Mobility Management Entity, referred to as MME), policy charging rule function (Policy and Charging Rule Function, referred to as PCRF), gateway (Serving Gateway, referred to as S-GW) and packet data gateway (PDNGateway, referred to as P-GW).
Please refer to Fig. 1, Fig. 1 is according to the structural representation of the packet-based core networks (Evolved Packet Core, referred to as EPC) of the 3GPP of correlation technique and non-3GPP connecting system access evolution.
As shown in Figure 1, EPS system is supported 3GPP access.HSS is the permanent storage place of user contracting data, is positioned at the signing home network of user; MME is responsible for the processing of mobile management, Non-Access Stratum signaling and the chain of command correlation functions such as management of user mobility managing context; S-GW is the accessing gateway equipment being connected with 3GPP Access Network, forwarding data between 3GPP access and P-GW, and data are carried out to buffer memory; P-GW is the borde gateway of EPS and packet data network (Packet Data Network, referred to as PDN), is responsible for the access of PDN and the function such as forwarding data between EPS and PDN; PCRF is "Policy and Charging Rules Function entity, and it is connected with Operator Specific Service network by receiving interface Rx, is responsible for providing charging control, online credit control, thresholding to control and service quality (Quality of Service, referred to as QoS).
As shown in Figure 1, EPS system is also supported non-3GPP access.Wherein, by S2a/S2b/S2c Interface realization, P-GW is as the anchor point between 3GPP and non-3GPP access with the intercommunication of non-3GPP access.Non-3GPP access is divided into the non-3GPP access of credit and the non-3GPP access of non-credit.Wherein, the non-3GPP access of credit can directly be connected with P-GW by S2a interface, and S2a interface adopts proxy-mobile IP (Proxy Mobile IP, referred to as PMIP) agreement to carry out information interaction.The non-3GPP access of non-credit needs to be connected with P-GW through the packet data gateway (evolved Packet Data Gateway, ePDG) of evolution, and the interface between ePDG and P-GW is S2b.S2c interface provides subscriber equipment (UserEquipment, referred to as UE) and P-GW between user's face control and mobility support, the mobility protocol of its support is for supporting the mobile IP v 6 (Mobile IPv6support for Dual Stack Hosts and Routers, referred to as DSMIPv6) of two stacks.
At Long Term Evolution (Long Term Evolution, referred to as LTE) in system, even if the position between equipment is very contiguous, between equipment, also need to realize by base station and core net the transmission of communication data, considerable to the resource occupation of base station and core net.In order to improve resource utilization, increase base station and core net capacity, adjacent service (Proximity Services, referred to as ProSe) function, for providing the technology of direct communication between equipment.In prior art, the LTE that ProSe function can realize under LTE covers finds to communicate by letter with LTE.
The fast development of intelligent terminal and mobile Internet application, increases sharply Mobile data flow with speed difficult to the appraisal.In order effectively to alleviate flow pressure, the lasting development that promotes mobile communication business, WLAN (wireless local area network) (Wireless LocalArea Network selects to greatly develop in the increasing operator in the whole world, referred to as WLAN), and employing WLAN low-cost, high bandwidth is Cellular Networks shunting.
In traditional wlan system, even if the position between equipment is very contiguous, between equipment, also need to realize by access point and access controller the transmission of communication data, considerable to the resource occupation of access point.In order to improve the resource utilization of access point, increase access point capacity, in prior art, between the equipment of support Wi-Fi function, also can be configured to wireless self-organization network (Ad hoc) pattern, realize the direct communication between Wi-Fi equipment.In prior art, support that Wi-Fi directly connects between the equipment of (Wi-FiDirect) technology, and support, between Wi-Fi Direct technology and the equipment of traditional Wi-Fi technology, also can realize the direct communication between Wi-Fi equipment.
Yet there are the following problems for prior art:
Most of LTE/Wi-Fi terminal or single-mode terminal, can only be operated under a kind of access module, generally can select to be operated under LTE pattern, only under special scenes, just opens Wi-Fi wireless switching.Even for the dual-mode terminal of supporting LTE/Wi-Fi, user may also can close Wi-Fi wireless switching based on considerations such as power savings, and select to be operated under LTE pattern.Like this, even if user is very contiguous, may also not necessarily can become Ad hoc pattern or use Wi-Fi Direct technology to carry out WLAN direct communication by option and installment.
For notifying neighbours to open the problem that Wi-Fi switch carries out WLAN direct communication in correlation technique, effective solution is not yet proposed at present.
