Embodiment
The method that the purpose of this invention is to provide a kind of operating capability negotiation continually, when this method changes in the application power of DIAMETER node, do not need to disconnect and consult successful link and rebulid again, and directly initiating capacity exchange request message carries out the link capability negotiation, in the hope of reaching the purpose that on-the-fly modifies DIAMETER link application power.
As shown in Figure 1, Fig. 1 is the message flow schematic diagram of the method for the invention, specifically can may further comprise the steps:
Step 101: between two DIAMETER nodes (node A and Node B) handling capacity consult and consult successfully, two nodes are all supported set of applications 1, Link State is respectively I-Open and R-Open, promptly Link State is the capability negotiation success status; Behind the capability negotiation, mutual application DIAMETER message of receiving and dispatching set of applications 1 between two DIAMETER nodes.
Step 102: as required, application power changes on the DIAMETER node, need carry out capability negotiation again.Simultaneously, the state that detects the peers include both state machine is I-Open (perhaps R-Open), and then directly initiating capacity exchanges request message, and capability negotiation is carried out in request.Here changing and initiate CER message with node A application power is example, changes the application power that back local terminal (being node A) is supported with going up application power in the CER message.
Step 103: Node B is received CER message when state is R-Open (perhaps I-Open), application power according to the application power of carrying in the CER message and this DIAMETER (being Node B) self is judged, if the application power of the application power of carrying in the CER message and this DIAMETER (being Node B) self has non-NULL to occur simultaneously, the application power that the support of this DIAMETER node is described or partly supports to carry in the CER message, again consult successfully, reply CEA message, Result-Code is changed to DIAMETER_SUCCESS, carried out for the 104th step then; Otherwise Node B is not supported the application power of carrying among the CER, consults failure again, in the CEA message of answer Result-Code is changed to DIAMETER_NO_COMMON_APPLICATION, disconnects transport layer and connects.
It should be noted that, after Node B is received CER message, as long as the application power of carrying in the application power of local terminal support and the CER message is occured simultaneously not for empty, the application power that common support is promptly arranged, just think and consult again successfully, this common factor is consults posterior nodal point A and the common set of applications of supporting (being defined as set of applications 2 among the present invention) of Node B again, in the CEA response message of replying Result-Code is changed to DIAMETER_SUCCESS.
Step 104: through after consulting again, support set of applications 2 jointly between node A and the Node B, receive and dispatch the application DIAMETER message of set of applications 2 mutually.
Certainly, change, and the peers include both state machine is when being R-Open (perhaps I-Open) if Node B detects the application power of local terminal support, also can initiating capacity exchange request message CER, carry the application power of this DIAMETER support.If node A receives CER message when state is I-Open (perhaps R-Open), it is identical with step 103 to handle the CER message flow.If promptly node A also supports the application power of carrying in the CER message, then reply CEA message, Result-Code is changed to DIAMETER_SUCCESS, capability negotiation success, execution in step 104; If node A does not support the application power of carrying in the CER message then in the CEA message of Hui Fuing Result-Code to be changed to DIAMETER_NO_COMMON_APPLICATION, the capability negotiation failure disconnects transport layer and connects.
This is I-Open (perhaps R-Open) at Link State, when local terminal supports that application power changes, not chain rupture and directly carry out the mode of capability negotiation, no matter simplified chain rupture flow process and the increase of this end node application power or the minimizing of link setup again, can not exert an influence for changing the application of all supporting the rear and front end.
