Description
Technical field
The present invention relates to the communications field, and especially, relate to a kind of evolved packet system (Evolved Packet System, EPS) position information of user equipment Notification Method and system of being used for.
Background technology
The grouping system of 3GPP evolution is by public land wireless access network (the EvolvedUniversal Terrestrial Radio Access Network of evolution, abbreviate E-UTRAN as), mobile management unit (Mobility Management Entity, MME), gateway (ServingGateway, S-GW), data network gateway (Packet Data Network GateWay, PDN GW, abbreviate P-GW as,), home subscriber server (Home SubscriberServer, HSS), 3GPP aaa server (3GPP authentication and authorization charging server), "Policy and Charging Rules Function (Policy and Charging Rules Function, PCRF), and other support nodes are formed.
Wherein, MME is responsible for the processing of mobile management, Non-Access Stratum signaling, user's chain of command related works such as the contextual management of mobile management; S-GW is the accessing gateway equipment that links to each other with E-UTRAN, transmits data between E-UTRAN and PDN GW, and is responsible for pending datas such as paging are carried out buffer memory.P-GW then is that (Packet Data Network, the PDN) borde gateway of network be responsible for the access of PDN, transmit function such as data between EPS and PDN for grouping system (EPS) and the packet data network of 3GPP evolution.
When UE inserts by E-UTRAN, both can adopt the GTP agreement between S-GW and the P-GW, also can adopt the PMIPv6 agreement.Simultaneously, EPS realizes and the intercommunication of non-3GPP network that by the S2a/b/c interface P-GW is as 3GPP and the internetwork anchor point of non-3GPP.Wherein, non-3 GPP system is divided into the non-3GPP IP access of trusted and trustless non-3GPP IP access.The non-3GPP IP of trusted inserts can be directly by S2a and P-GW interface; Trustless non-3GPP IP inserts to be needed to link to each other with P-GW through ePDG (Evolved PacketData Gateway, the data gateway of evolution), and the interface between ePDG and P-GW is S2b.The S2a interface is supported MIPv4 agreement and PMIPv6 agreement, and the S2b interface is supported the PMIPv6 agreement.S2c is the interface between UE and the P-GW, adopts two stack mobile IP v 6 (Dual Stack Mobile IPv6, DSMIP v6) agreements that control and mobile management are provided.
In the EPS system, strategy and charge execution function (Policy and chargingenforcement function abbreviates PCEF as) are present in P-GW, and PCRF and P-GW are by S7 interface exchange message.When the interface between S-GW and P-GW during based on PMIPv6, resident bearing binding and event reporting function (the Bearer Bindingand Event Reporting Function of being called among the S-GW, BBERF), as shown in Figure 1, pass through S7c interface exchange message between S-GW and the PCRF.When UE inserted by the non-3GPP connecting system of trusted, the also resident BBERF in the trusted non-3 GPP access network Central Shanxi Plain as shown in Figure 1, passed through S7a interface exchange message between trusted non-3 GPP access network pass and the PCRF.
In the EPS system, when adopting the PMIPv6 agreement between UE is by E-UTRAN access and S-GW and P-GW or UE when inserting by non-3GPP IP, P-GW is responsible for collecting charging information and charge information is sent to the charging center.Generally include the UE current position information in the charge information, for example, UE is roaming or non-roaming.Under the situation of UE, confirm further which visited network UE is in for roaming; Under the situation that UE inserts by E-UTRAN, can also be accurate to the subdistrict position at UE place etc. according to the demand of operator.
At present, when having disposed dynamic PCC in the network, user's current position information can send to PCRF by S-GW or the non-3GPP IP of trusted IAD, PCRF will comprise that user's current location information relevant information and charging information collecting strategy etc. are handed down to P-GW, afterwards, P-GW sends to the charging center with charge information again.
But, the technical scheme that makes P-GW obtain the current location information of UE under network is not disposed the situation of dynamic PCC and location information notification is given charge system is not proposed at present as yet.
Summary of the invention
