Description
Technical field
The invention belongs to next generation network communication field, particularly relate to a kind of AGCF endpoint registration cancellation method based on chained list.
Background technology
Soft switch plays key player in the process of legacy circuit-switched IPization, and through development for many years, Softswitch technology is comparatively ripe.IMS (IPMultimediaSubsystem, IP multimedia system) is a kind of brand-new multimedia service form, and it can meet present terminal client demand that is more novel, more diverse multimedia business.IMS can be regarded as a kind of new Softswitch technology.IMS system comprises three functional planes: Access Layer, core layer and operation layer.Various access network is aggregated in IMS core net by Access Layer, completes the intercommunication of existing network and the control that completes carrying, comprises the network elements such as MGW, AG; Core layer completes the Core Features such as Call-Control1, safety management, business triggering, resources control, network interworking, comprises the network elements such as S/I/P-CSCF, MRFC, HSS, AGCF, MGCF, BGCF; Operation layer provides various value-added service to realize, and as PSTN simulation services collection, Centrex services sets, presents business, instant messaging etc., comprises all kinds of AS network element.
AGCF (AccessGatewayControlFunction, AGCF) is as the key network element of IMS system core layer, complete the intercommunication of legacy network access user and IMS network, in IMS evolution process, play key player in fixed network soft switch.Still master is deployed as with stored-program control exchange, SoftSwitch in electric power, subway communication private network, how to realize program-controlled exchange network, flexible exchanging network seamlessly transitting to IMS network, concern the continuity of existing network investment and the inheritance of Softswitch technology, become communication network and develop key problem urgently to be resolved hurrily.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of based on existing soft switch media gateway control technology and registration management mechanism, the Register Cancel method of conventional terminal to IMS network is realized by technological transformation, be beneficial to and realize the evolution of traditional soft switching system to IMSAGCF network element, shorten new product development cycle, and the technology that achieves is inherited and reuses.Based on fixed network soft switchcall server by Software adapting, realize IMSAGCF Network Element Function, existing flexible exchanging network construction investment can be protected, IMS can be realized again to the succession in Softswitch technology with reuse, advance soft switch to the evolution of IMS.
Technical scheme of the present invention is: a kind of AGCF endpoint registration cancellation method based on chained list, is characterized in that comprising the following steps:
Step 1:AGCF system is each conventional terminal unique corresponding distribution IMS terminal, and AGCF system deposits middle establishment three chained lists within it, ON cycle driving timing device after starting; Three described chained lists are respectively: unregistered chained list, register chained list and registered chained list;
Step 2: one or more conventional terminal initiates registration request respectively to AGCF system, and IMS terminal corresponding for each conventional terminal is placed into unregistered chained list;
Step 3: after super during circulation driving timing device, AGCF system initiates registration request to IMS network take out N number of IMS terminal from unregistered chained list after, and from unregistered chained list, removes described N number of IMS terminal be then placed into and register chained list; Wherein, N is natural number;
Step 4:AGCF system judges whether each IMS terminal succeeds in registration respectively, if succeeded in registration, if IMS terminal is in register chained list, from wherein removing and being placed into registered chained list, if IMS terminal is in registered chained list, continue to remain on registered chained list, process ends; If registration failure, perform step 5;
Step 5: if IMS terminal is in register chained list, after again initiating registration request, proceeds to step 4; If IMS terminal is in registered chained list, from wherein remove and be placed into register chained list after again initiate registration request, proceed to step 4.
Wherein, also comprise after step 4: after super during circulation driving timing device, upgrade registering IMS terminal in chained list re-register duration, when re-registering duration and being 0, proceed to step 2; After super during circulation driving timing device, upgrade duration life cycle of IMS terminal in registered chained list, initiate when life cycle, duration was 0 to re-register, proceed to step 2.
Wherein, described conventional terminal is MEGACO terminal, MGCP terminal, non-IMSSIP terminal or H.323 terminal.
Based on an AGCF terminal log-down method for chained list, comprise the following steps:
Step 1:AGCF system is each conventional terminal unique corresponding distribution IMS terminal, and AGCF system is deposited middle establishment within it and nullified chained list, ON cycle driving timing device after starting;
Step 2: conventional terminal or IMS network initiate de-registration request to AGCF system, AGCF system scans unregistered chained list successively, registers chained list and registered chained list, removes IMS terminal corresponding to the conventional terminal that will nullify and be placed into cancellation chained list from described 3 chained lists;
Step 3: after super during circulation driving timing device, AGCF system update nullifies the cancellation timing length of each IMS terminal in chained list, when cancellation timing length is 0, AGCF system is initiated to nullify or initiate respectively to nullify to the conventional terminal that will nullify to IMS network;
Step 4: remove being in each IMS terminal of nullifying chained list.
Wherein, the conventional terminal described in step 2 or IMS network initiate de-registration request, are specially: one or more conventional terminal initiates de-registration request respectively to AGCF system or IMS network initiatively initiates network de-registration request.
Wherein, described conventional terminal is MEGACO terminal, MGCP terminal, non-IMSSIP terminal or H.323 terminal.
The beneficial effect adopting such scheme to produce is: based on existing Softswitch technology basis, function is nullified by increasing endpoint registration, just soft switch can be realized to the critical function needed for the evolution of IMSAGCF network element, shorten new product development cycle, and achieve IMS to the succession of Softswitch technology with reuse.
