Description
Technical field
The present invention relates to mobile communication technology field, relate in particular to a kind of based on IMS(IP Multimedia Subsystem, internet protocol multimedia subsystem) calling-control method, Apparatus and system.
Background technology
In order to meet more novel, the more diversified multimedia service demand of user, 3GPP(The3
rdgeneration Partnership Project, third generation partner program) be organized on the basis of original packet carrying network and introduced IMS, IMS is considered to the core technology of next generation network, it can not only provide traditional speech business to user, can also provide abundant multimedia experiences to user, be to solve mobile and fixed network fusion, introduce the important way of the differentiated services such as voice, data, video Triple Fusion.
At present, the main network element of IMS network comprises: CSCF(Call Session Control Function, controlling call entity), HSS(Home Subscriber Server, home subscriber server) and AS(Application Server, application server), wherein:
Described CSCF can be divided into P-CSCF(Proxy-Call Session Control Function, proxy call conversation control function entity), I-CSCF(Interrogating-Call Session Control Function, query call conversation control function entity) and S-CSCF(Serving-Call Session Control Function, service call session control function entity) three types, wherein, S-CSCF, as IMS server controlling call entity, can realize basic CCF;
Described HSS realizes routing function and the functions such as authentication, mandate is provided for recording each user's of IMS network user contracting data, cooperation CSCF; Wherein, described user contracting data can download to S-CSCF from HSS when user registers, and the IFC(Initial Filter Criteria that includes user in described user contracting data, service trigger criteria, also can be described as initial filter criteria), in described IFC, include the address information of the AS that business is provided; User is when calling out, and S-CSCF can be triggered to according to the configuration information in IFC corresponding AS, by corresponding AS, to user, provides its required speech business, video traffic or other supplementary services etc.;
Described AS is as the visual plant of IMS network, corresponding control is carried out in the calling that can be triggered to self to S-CSCF, and return to call out and put logical or to call out and discharge response message to S-CSCF, so that S-CSCF calls out and puts logical or release processing Client-initiated according to the call message receiving, thereby, when AS fault, will directly affect user's service-aware.Particularly, in order to address the above problem, in 3GPP IMS related specifications, define, when AS fault, the continuing of user's call session controlled " Default AS Handing(disaster tolerance parameter) " in IFC retrained, and when described disaster tolerance parameter is set to " SESSION_CONTINUED(call out put logical) ", S-CSCF can be put logical calling, when described disaster tolerance parameter is set to " SESSION_TERMINATED(calls out termination) ", can discharge/end call of S-CSCF.
But, when adopting the mode of the above-mentioned control of carrying out user's calling according to the disaster tolerance parameter in IFC, can there is following problem:
Problem one, when called number is long code, all-calls all can be put logical, cannot control flexibly according to the call authority of calling number;
Problem two, when called number be short codes or while needing number regular, due to the conversion of long cornet or number is regular etc. that operation need be undertaken by AS, therefore, when AS fault, the failure that can cause this part to be called out;
Problem three, for called one number service, especially CS territory (circuit domain) termination number is done the called one number service of major number, because its number translated part need be undertaken by AS, therefore, when AS fault, the failure that can cause this part to be called out.
For fear of the problems referred to above, when AS fault, also can adopt the mode of disposing AS disaster tolerance equipment to solve the call exception problem that primary AS fault is brought.For example, when a certain AS fault, HSS can be forwarded to the customer service that belongs to fault AS on normal AS; Or, by the change data script of the primary AS database of regular generation, thereby and on standby AS, carry out and complete the synchronous of database.
But, when the mode of adopt disposing AS disaster tolerance equipment solves the call exception that primary AS fault brings, there is the problem that when is switched to disaster tolerance equipment.The current general OPTIONS(of employing function) detect and link detecting scheme, in primary AS equipment fault or delay the complete failures such as machine in the situation that, can realize the quick switching of primary, spare equipment; But, in primary AS environment division fault, as primary AS equipment can move but network quality is not high to be caused calling out under the scene that packet loss or primary AS equipment exhales etc. due to software and hardware defect limit, it cannot be switched to disaster tolerance equipment fast, thereby in causing during this period, do not have perfect calling and put logical mechanism, the business that can greatly affect user is used, and reduces user's business experience.
Have again, when the mode of adopt disposing AS disaster tolerance equipment solves the call exception that primary AS fault brings, because the data of stand-by equipment generally have certain hysteresis quality than host apparatus, therefore, after enabling, disaster tolerance equipment may still can there is the problem of call exception under part scene, also can further make user's business be affected, reduce user's business experience.
In sum, when AS fault is when (comprising complete failure or partial fault), no matter to adopt when carrying out the control of user's calling or adopting the mode of disposing AS disaster tolerance equipment to solve the call exception problem that AS fault brings according to the disaster tolerance parameter in IFC, all cannot reach in time the calling that S-CSCF is triggered to each AS and carry out the effect of rationally controlling neatly, can cause customer service impaired, reduce user's business experience.
