301, mobile terminal sends IP Address requests to fixed network Node B NG.

Wherein, in IP Address requests, can comprise terminal iidentification, so that BNG determines according to terminal iidentification whether the terminal equipment of transmission IP Address requests is mobile terminal.

302, fixed network Node B NG sends to mobile terminal by the IP address of distribution.

It should be noted that, fixed network Node B NG can the pre-configured ePDG that one or more is connected with mobile terminal address, after BGN has distributed IP address to mobile terminal, can not open the local data unloading access of mobile terminal, that is to say, packet route between this mobile terminal and ePDG can be by BNG route processing, and this locality of this mobile terminal unloading data access will be by BNG route processing.

Or, the local data unloading access of directly opening mobile terminal when fixed network Node B NG has distributed IP address to mobile terminal.

303, mobile terminal, according to the IP address obtaining, is set up PDN with the gateway entity of network side and is connected, and by PDN Gateway, fixed network access sign is passed to policy control entity.

In the present embodiment, fixed network access sign (fix access identifier) represents the fixed network node identification at mobile terminal to access fixed network place, for example, be BNG sign.

During specific implementation, for example, after mobile terminal obtains IP address by fixed network node, mobile terminal can access PS business, packet data gateway (Eolved Packet Data Gateway with evolution, ePDG) complete the tunnel authentication based on IKEv2, after authentication, set up the tunnel between mobile terminal and ePDG; By the tunnel of setting up, mobile terminal is set up access point network 1(Access Point Network1, APN1) corresponding PDN connects, and fixed network access sign is carried and is delivered to grouped data network gateway (Packet Data Network Gateway, PDN GW) via ePDG.

PDN Gateway is according to mobile terminal identification, for example, international mobile subscriber identity (International Mobile SubscriberIdentification Number, IMSI) and APN1 Information Selection strategy and charging control (Policy and Charging Control, PCC) node, PCRF entity for example, with between PCRF entity, set up IP and be connected access to network conversation (IP Connectivity Access Network session, IP-CAN session), PDN Gateway passes to PCRF entity by IP-CAN session by fixed network access sign.

Or PDN Gateway passes to charging center OCS/OFCS by Gy/Gz interface by mobile terminal identification and fixed network access sign, particularly, mobile terminal is set up PDN with PDN Gateway and is connected, by PDN Gateway, fixed network access sign is sent to charging center OCS/OFCS, charging center OCS/OFCS finds corresponding fixed network Node B NG according to fixed network access sign, and to fixed network Node B NG, issues the control of local unloading data access and charging policy by the Gy/Gz interface between charging center OCS/OFCS and fixed network Node B NG.

It should be noted that, charging center OCS/OFCS by and fixed network Node B NG between Gy/Gz interface to fixed network Node B NG issue that local unloading data access is controlled and charging/charging policy before, also comprise: charging center OCS/OFCS obtains this locality unloading data flow stream description information of mobile terminal from PDN Gateway, according to this locality unloading data flow stream description information of obtaining, charging center OCS/OFCS decision-making is carried out charging to mobile terminal ground unloading data flow originally.If charging center OCS/OFCS decision-making is not carried out charging to this locality unloading data of mobile terminal, charging center OCS/OFCS can not trigger to fixed network Node B NG and issue the control of local unloading data access and charging policy.

304, policy control entity, according to fixed network access sign, sends this locality unloading data access control and charging policy and the mobile terminal identification of mobile terminal to fixed network Node B NG.

During specific implementation, for example, when policy control entity is PCRF entity, PCRF can be according to the control strategy of self or also can for example, according to the information of other network bodies (OCS center), be triggered, initiation is controlled and charging policy this locality unloading data access of mobile terminal, PCRF policy control entity can trigger on S9a interface and broadband policy is controlled function (Broadband Policy Control Function, BPCF) between policy control entity, set up gateway control session, or PCRF entity directly issues local unloading data access by the gateway control session on the Gxd interface between PCRF entity and BNG (Gateway Control Session) or IP connected reference BlueDrama (IP-CAN Session) to BNG and controls and charging policy.

It should be noted that, above-mentioned by under the scene of S9a interface, in the gateway control session that PCRF entity can be carried at S9a interface by this locality unloading data access control of fixed network access sign and mobile terminal and charging policy, pass to BPCF entity, more further by the R interface between BPCF and BNG, be handed down to BNG by BPCF entity processed.During specific implementation, when BPCF policy control entity is received the message from the gateway control session on the S9a interface of PCRF policy control entity, BPCF can obtain the fixed network access sign (BNG sign) of carrying in the message of gateway control session, by R interface, to BNG, send service quality (Quality of Service, QoS) authorization requests, BPCF policy control entity can be controlled this locality unloading data access of mobile terminal and charging policy is carried in QoS authorization requests and sends to BNG.

Again for example, when policy control entity is charging center OCS or OFCS, charging center OCS/OFCS is according to the sign of the mobile terminal obtaining and fixed network access sign, charging center OCS/OFCS sets up online with BNG or offline charging is connected, charging center OCS or OFCS send local unloading data access to BNG and control and charging policy, require BNG to carry out the collection of charge information to this locality unloading data flow, and charge information is reported to charging center OCS/OFCS.

Again for example, when policy control entity is 3GPPAAA certificate server, 3GPP aaa server can be according to the control strategy of self or also can for example, according to the information of other network bodies (OCS center), be triggered, initiation is controlled and charging policy this locality unloading data access of mobile terminal, 3GPP aaa server can send this locality unloading data access control of mobile terminal and charging policy and BNG to the BBF AAA/BBF AAA of broadband forum agent entity by STa/SWa interface and identify, BBF AAA/BBFAAA agent entity this locality unloading data access of mobile terminal can be controlled and charging policy sends to BNG,

During specific implementation, 3GPP aaa authentication server obtains sign and the fixed network access sign of mobile terminal in the tunnel verification process to mobile terminal, and can or also can for example, according to the information of other network bodies (OCS center), trigger this locality unloading data access obtaining mobile terminal and control and charging policy according to the control strategy of self, 3GPP aaa server by STa/SWa interface, this locality unloading data access of the mobile terminal of acquisition is controlled and charging policy is handed down to broadband forum (BBF) aaa server; Broadband forum (BBF) aaa server is controlled by this locality unloading data access of moving terminal and charging policy is handed down to fixed network Node B NG.

It should be noted that, tunnel of the present invention authentication refers to mobile terminal accessing packet data network, for example, the tunnel authentication based on IKEv2 between terminal and mobile network node (ePDG), after this tunnel authentication success, for example, between mobile terminal and mobile network node (ePDG), set up IPsec secure tunnel.

Again for example, when policy control entity is charging center OFCS or OCS, charging center OFCS/OCS can initiate this locality unloading data access of mobile terminal to control and charging policy according to the control strategy of self, for example, trigger BNG this locality unloading data access is carried out to the collection of charge information.

It should be noted that, Gz interface between BNG support and OFCS, or the Gy interface between support and OCS, charging center OFCS/OCS is undertaken alternately by Gz or Gy interface and BNG respectively, and this locality unloading data access that sends mobile terminal to BNG is controlled and charging policy.
