example 1

[0107] Example 1: Establishment of an initial PMIP binding

[0108] Such as image 3 As shown, the processing in this example is as follows:

[0109] (1) AT performs successful authentication and authorization process, AGW receives AAA-session identifier and other parameters from home AAA (HomeAAA-HAAA). AGW selects a unique random key for AT called PMN-AN-RK, And thus derive PMN-AN-RK1. AGW sends PMN-AN-RK1, AAA-session identifier and other related parameters to SRNC. AGW also sends its PMIP binding capability to SRNC at the same time;

[0110] (1') SRNC obtained the AGW support PMIP binding capability and other parameters;

[0111] (2) eBS1 sends an IAS session information request message to SRNC to obtain relevant session information;

[0112] (3) After receiving the session information request, SRNC responds with an IAS-session information response message, which includes AGW IP address, LinkID, user name, AAA-session ID, PMN-AN-RK1, and PIMP binding supported by AGW ...

example 2

[0123] Example 2: Addition of AT routing set

[0124] Such as Figure 4 As shown, in this example, the following processing procedures are included:

[0125] (a) AT is currently connected to eBS1, and SRNC is in the routing set;

[0126] (b) AT sends a RouteOpenRequest message to eBS2 through a tunnel to add eBS2 to the routing set;

[0127] (c) eBS2 sends an IAS-Session Information Request message to SRNC;

[0128] (d) SRNC responds to eBS2 with an IAS-Session Information Response message, which includes the PMIP binding capability supported by AGW;

[0129] (e) eBS2 sends a RouteOpenAccept message to AT;

[0130] (f) AT and eBS1 are in the connected state, and eBS2 and SRNC are also in the routing set;

[0131] (g) AT sends a RouteMap message to each member in the routing set;

[0132] (h * ) eBS2 sends a PMIP-Registration Request message to the AGW to establish an additional data tunnel according to the PMIP capability of the AGW, and the RLOnly Type Extension is inc...

Abstract

The invention discloses an access gateway binding establishment method, comprising: SRNC obtains the PMIP binding capability supported by AGW; when eBS obtains session information from SRNC, SRNC sends the PMIP binding capability supported by AGW To eBS; eBS saves the PMIP binding capability supported by AGW, and sends a proxy mobile IP registration request message to AGW to establish corresponding binding for AGW according to the eBS's own capabilities and the acquired PMIP binding capability supported by AGW . In addition, the invention also discloses an access gateway binding establishment system. By using the present invention, the PMIP support capability of the AGW can be transmitted in the access network, thereby realizing the optimization of the establishment process of the PMIP binding between the eBS and the AGW in the UMB network, and avoiding unnecessary signaling interaction.

Description

technical field [0001] The present invention relates to the field of ultra mobile broadband (Ultra Mobile Broadband, UMB) communication, and in particular, relates to a method and system for establishing an access gateway binding. Background technique [0002] Different access technology fields of wireless communication are researching and developing the evolution of the corresponding technology in a period of time in the future, so as to improve the performance and service capability of the system. UMB is the evolution technology of Code Division Multiple Access (CDMA) 2000 access technology. Many technologies of UMB air interface can greatly improve the performance of CDMA 2000 access technology network, thus providing users with more wireless multimedia services with higher requirements. Essential basis. [0003] In order to support the UMB air interface technology, the corresponding network is also undergoing new evolution. figure 1 It is a network structural block dia...
