Description
Technical field
The present invention relates to the communications field, and especially, relate to a kind of Notification Method and system of user equipment access protocol.
Background technology
As shown in Figure 1, third generation partner program (3rd Generation Partnership Project, 3GPP) the grouping system of evolution (Evolved Packet System, EPS) comprising: the UTRAN of evolution (Evolved Universal Terrestrial Radio Access Network, E-UTRAN), mobile management unit (Mobility Management Entity, MME), gateway (Serving Gateway, S-GW), data network gateway (Packet Data Network Gateway, PDN GW, promptly, P-GW), home subscriber server (Home Subscriber Server, HSS), 3GPP authentication and authorization charging server (3GPP aaa server), "Policy and Charging Rules Function (Policy and Charging Rules Function, PCRF), and other support node.
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 (Evolved Packet System EPS) with the borde gateway of PDN network, is responsible for the access of PDN, transmits function such as data between EPS and PDN for the grouping system of 3GPP evolution.PCRF obtains business information by Rx interface and operator's IP operation network interface, and links to each other with gateway device in the network by S7/S7a/S7c, is responsible for initiating the foundation of IP carrying, guarantees the QoS of business datum, and the control of chargeing.
And EPS also supports the intercommunication with non-3GPP network.As shown in Figure 1, the intercommunication of EPS and non-3GPP network realizes 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-3GPPIP 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 access then need be passed through ePDG (Evolved Packet Data Gateway, the packet data gateway of evolution) and link to each other with P-GW, and the interface between ePDG and P-GW is S2b.S2c is the interface between UE and the P-GW, adopts the DSMIPv6 agreement that control and mobile management are provided.
MIPv6 (Moblie IPv6) by to mobile node (Mobile Node, the binding of IPv6 Care-of Address CoA MN) and IPv6 home address HoA come to MN in network when mobile the accessibility and the continuity of session provide support.But because IPv6 is not also disposed widely, in very long from now on a period of time, the network of IPv4 also will exist in a large number.Therefore, the MN of IPv6 tends to move on the network of not supporting IPv6, so just must expand MIPv6.
Two stack mobile IP v 6s (Dual Stack Mobile IPv6, DSMIPv6) be exactly a kind of scheme that can effectively solve this scaling problem, this scheme requires mobile node MN and home agent (Home Agent) all to need to support DSMIPv6 based on the MIP agreement of client (Client-based).The MN of support DSMIPv6 comes its mobility on IPv4 or IPv6 network is provided support by the binding of its IPv4/IPv6 Care-of Address and IPv4/IPv6 home address.
In traditional 3GPP network, strategy and charge execution function (PCEF, Policy and charging enforcement function) entity exists only among the P-GW, policy control and charging rule functions (Policy Control and charging rules function, PCRF) entity needs only the control that can finish all functions with the P-GW interface, pass through S7 interface exchange message between PCRF and P-GW, as shown in Figure 1.Interface when between P-GW and S-GW is based on proxy mobile IPv 6 (Proxy Mobile IPv6, PMIPv6) time, policy enforcement function part in the PCEF function also is present among the S-GW, be called bearing binding and event reporting function (Bearer Binding and Event Reporting Function, BBERF) entity, pass through S7c interface exchange message between S-GW and the PCRF, as shown in Figure 1.When inserting by the non-3GPP connecting system of trusted, the also resident BBERF entity in the trusted non-3 GPP access network Central Shanxi Plain.And, as shown in Figure 1, pass through S7a interface exchange message between trusted non-3 GPP access network pass and the PCRF.When UE roamed, the S9 interface was as the interface of ownership place PCRF and visit ground PCRF.(Application Function, AF) entity sends to PCRF by the Rx+ interface and is used for generation strategy and charges control (Policy and Charging Control, business information PCC) for UE provides professional application function simultaneously.Here, S7, S7a, S7c and Rx+ interface all adopt Diameter.
The handling process that Fig. 2 switches to the trusted non-3 GPP access network and adopts the DSMIPv6 agreement to insert from 3GPP for UE.By this processing, UE can set up one to Packet Data Network (Packet Data Network, PDN) IP connects, and can also set up a DSMIPv6 tunnel simultaneously between UE and P-GW, the trusted non-3 GPP access network closes on this tunnel.As shown in Figure 2, its concrete processing procedure is as follows:
202, set up RAB between UE and the S-GW, set up the PMIPv6 tunnel between S-GW and the P-GW;
204, UE finds the non-3GPP connecting system of trusted and initiates to switch;
206, UE carries out access authentication in non-3GPP connecting system, and home subscriber server/authentication and authorization charging server (HSS/AAA) carries out access authentication to UE, and closes the address of returning the P-GW that UE connects in the 3GPP system to the trusted non-3 GPP access network;
208, the layer of setting up UE and the non-3GPP connecting system of trusted behind the authentication success 3 is connected, and Access Network is the Care-of Address CoA of UE distribution local ip address as DSMIPv6;
210, the trusted non-3 GPP access network closes to PCRF and sends " gateway control session foundation " request, carry network access Identifier NAI and Care-of Address CoA in the message, at this moment owing to have only the CoA of UE, and CoA is distributed by the trusted non-3 GPP system, so do not have UE will insert the information of PDN on the PCRF, can not issue qos policy based on PDN;
212, PCRF returns " gateway control session is set up and confirmed ", carries qos policy in the message;
214, UE carries out the IP address that DNS inquiry obtains the P-GW that will insert according to APN, and sets up the Security Association of UE and P-GW, and UE obtains home address HoA;
216, UE sends " Binding Update " request to P-GW, carries HoA and CoA in the message;
218, P-GW carries out IP alternately with PCRF and is connected Access Network (IP Connectivity Access Network, IP-CAN) session modification;
220, P-GW returns binding acknowledgement;
222, PCRF close to send gateway control and the QoS rule gives information to the trusted non-3 GPP access network, carries QoS rule and MIP packaging information in the message, the trusted non-3 GPP access network closes installs the QoS rule, and wherein, the QoS rule is based on PDN information;

Fig. 3 is the handling process of UE by switching to the trusted non-3 GPP access network from 3GPP and adopting the PMIPv6 agreement to insert.Handle by this, UE can set up an IP to PDN and connect, and can also set up a PMIPv6 tunnel simultaneously between trusted non-3 GPP access network and P-GW.As shown in Figure 3, its concrete steps are as follows:
302, set up RAB between UE and the S-GW, set up the PMIPv6 tunnel between S-GW and the P-GW;
304, UE finds the non-3GPP connecting system of trusted and initiates to switch;
306, UE carries out access authentication in non-3GPP connecting system, and HSS/AAA carries out access authentication to UE, and closes the address of returning the P-GW that UE connects in the 3GPP system to the trusted non-3 GPP access network;
308, the attaching process of trigger layer 3;
310, the trusted non-3 GPP access network closes to PCRF transmission gateway control session and sets up request message, wherein, carry network access Identifier NAI and IP address in this message, and PCRF issues qos policy, because the IP address is distributed by P-GW, therefore comprised the information that UE will insert PDN in this address, the qos policy that PCRF issues is based on PDN's;
312, PCRF returns gateway control session and sets up affirmation, carries qos policy in this message;
314, the trusted non-3 GPP access network closes to P-GW and sends agent binding update messages;

320, layer 3 adheres to and finishes;
322, the PMIPv6 tunnel between trusted non-3 GPP access network pass and the P-GW is set up and is finished, and UE can send or receive the IP packet.
Adhere to processing procedure as can be seen from above-mentioned two, when UE adopted DSMIPv6, function and flow process performed when function that PCRF is performed and flow process and employing PMIPv6 agreement were inequality.
When adopting the DSMIPv6 agreement, receive gateway control session when setting up at PCRF, the PDN information that the policing rule that PCRF issues will not insert based on UE, and PCRF and PCEF carry out mutual after, also to initiatively issue the policy control rule that will insert PDN information and give BBERF based on UE.And on the other hand, when adopting the PMIPv6 agreement, PCRF receives gateway control session when setting up, and the policing rule that PCRF issues just is based on PDN information that UE will insert.
In addition, when UE adopted the DSMIPv6 agreement, PCRF also will provide the packaging information of MIP, for the correct filtering data bag of BBERF except common business datum flow filter is provided.In present correlation technique, it is to adopt the Diameter application protocol to realize that gateway control session foundation and gateway control session are set up acknowledge message.The IP address of UE all is to (Attribute Value Pairs by the property value in the Diameter application protocol, AVP) carry, its attribute is called Framed-IP-Address (this property value carries the IPv4 address to being mainly used in) and Framed-IPv6-Prefix (this property value carries the IPv6 address prefix to being mainly used in).AVP is used for the unit of the information of carrying in the Diameter.Its form generally includes AVP sign indicating number, AVP mark, AVP length and AVP data value.Wherein, the AVP sign indicating number is used for identifying the attribute of this AVP, and is corresponding with attribute-name, is responsible for distributing by IANA; The AVP mark is to inform how the recipient handles this attribute; AVP length represents that the length AVP data value of this AVP then represents the value of the data that this AVP carries.
If all carry by the AVP of Framed-IP-Addres or Framed-IPv6-Prefix the IP address when CoA when UE adopts the DSMIPv6 agreement to insert and employing PMIPv6 insert, just can not judge when PCRF receives that gateway control session is set up message that so UE has adopted the DSMIPv6 agreement or adopted the PMIPv6 agreement, also just can not determine to start which kind of flow process and function.
At this problem, a kind of solution that has proposed at present is to introduce parameter mobility protocol type (Mobility Protocol Type, MPT), and in gateway control session set up and the IP-CAN session sets up that to carry this parameter in indication or the IP-CAN session modification message be accesses such as employing PMIPv6 or DSMIPv6 in order to expression UE.Yet, realize that this scheme existence need increase new parameter in gateway control session foundation and IP-CAN session foundation indication or IP-CAN session modification message, this will increase the burden of system.
