The invention provides a download and treatment system and a method of initial filtering rule, wherein, a calling conversation control function entity and a home subscriber server both support shared initial filtering rule set. The system includes: an initial filtering rule setup device, positioned on the side of the home subscriber server and used in the setting up of initial filtering rule activation list in business configuration data, in order to present the activate state relevant to the initial filtering rule of the shared initial filtering rule set; a download and treatment device, positioned on the side of the service calling conversation control function entity and used to download business configuration data from home subscriber server and obtaining the activate state of the initial filtering rule relevant to the shared initial filtering rule set in the activation list of the initial filter rule according to the business configuration data, as well as carrying out subsequent treatment.
Description
Technical field
The present invention relates to the communications field, relate more specifically to a kind of initial filter criteria (iFC, initial Filter Criteria) download and treatment system and method can be used for IP Multimedia System (IMS, IP Multimedia Core Network Subsystem).
Background technology
At present, third generation partner program (3GPP, 3
RdGeneration PartnershipProject) introduced the basic principle that is used for IMS network and service, adopt the thought of control and service detach, it is professional that the IMS key-course does not provide, only provide functions such as the necessary triggering of operation layer, route, charging, and business is provided by operation layer fully.
The professional triggering is the critical function of IMS key-course, is to be finished by the service call conversation control function (S-CSCF, Serving Call Session Control Function) of IMS key-course.User's professional trigger data is represented with " business configuration (Service Profiles) ", and is kept in the home subscriber server (HSS, Home Subscriber Server) as the part of user's configuration (User Profiles) data.As shown in Figure 1, it is the professional frame diagram that triggers of IMS, show the professional built-in function that triggers related network element, interface and each network element, wherein mainly comprise service call conversation control function (S-CSCF) 102, home subscriber server (HSS) 104 and application server (AS, ApplicationServer) 106.
When the user registers, or S-CSCF receives when exhale the initial request of session an end of non-registered users, or S-CSCF receives when a server generation works the initial request of exhaling session for Client-initiated, the business configuration data are downloaded to the S-CSCF from HSS, comprising initial filter criteria (iFC).
Professional trigger condition represents that by initial filter criteria according to the difference of user's signing service, can contain many initial filter criteria in a user's the business configuration, these initial filter criteria all have priority separately.S-CSCF assesses register requirement and conversation initial request according to these initial filter criteria, and according to assessment result these requests is sent to the application server (AS) of appointment, provides corresponding service by these application servers according to request.
In Fig. 2, show the block diagram of the trigger process of a call request.Wherein, the user has disposed two initial filter criteria X, Y, and S-CSCF mates call request according to priority orders and each rule, by the mode controlling call path of triggering, and provides professional via application server.If service appointment and un-activation, application server is to going into to exhale things and be left intact and directly returning.After S-CSCF receives response message, continue the initial filter criteria of coupling time priority, and trigger calling control to other application server.
Apparently, if service appointment and un-activation, S-CSCF still will trigger to application server according to initial filter criteria, thereby has caused unnecessary calling control redundancy.IMS control and service detach cause the HSS can't perception service, and all Business Processing all have application server to bear, and have also caused this unnecessary calling control redundancy on the one hand.For fear of this redundancy, introduce a kind of mechanism by application server notice HSS at specific user or business, which iFC can conductively-closed, thereby does not need to download to S-CSCF.
This mechanism is currently used dynamic service information of being correlated with by AS notice HSS by dynamic service active information (DSAI, Dynamic Service Activation Info) information element.If DSAI is a state of activation, show that then its iFC that is associated need download to S-CSCF by HSS; If DSAI is a unactivated state, show that then its iFC that is associated can conductively-closed, need not download to S-CSCF by HSS.
Fig. 3 shows the incidence relation of DSAI and iFC.DSAI is associated with an iFC at least, and all must be triggered to identical AS with the related iFC of DSAI, promptly only allow to be responsible for upgrading the DSAI value by an AS; IFC can be associated with one or more DSAI, also can not related DSAI.The incidence relation of DSAI and this implicit expression of iFC is responsible for safeguarding and storage by HSS.
Usually, each terminal use can have one or more business configuration, comprise many initial filter criteria (iFC) in each business configuration again, these initial filter criteria can be regarded some logical expressions as, the professional condition that triggers of expression and the destination of triggering, and use text mode to describe, data volume is big.Especially when customer volume is big, will directly have influence on the transmission performance of HSS and S-CSCF business configuration data download interface, and consume the memory space of HSS and S-CSCF, cause power system capacity or performance decrease.
Consider in actual applications, the signatory identical business of a lot of users, supplementary services such as the caller identification of all opening basically such as mobile network's user, calling transfer, promptly these customer services are all used same or analogous initial filter criteria.Some business in addition, as present business, need many iFC to be triggered to a plurality of application servers in certain sequence and just can finish this business.Therefore, 3GPP has introduced the notion of " share inceptive filtering rule set (SiFC, Shared iFC Sets)---below be referred to as to share the iFC collection " in business configuration, optimize the download and the storage of business configuration data.
Share the iFC collection and can share use for a plurality of business configuration, the related one or more initial filter criteria of each shared iFC collection, be kept at respectively in the local data base of HSS and S-CSCF,, use shared iFC set identifier to carry out unique expression by HSS and S-CSCF maintenance management respectively.Fig. 4 shows senior UML (UML, the Unified Modeling Language) model of business configuration class, comprising shared iFC collection assembly.Can define a plurality of shared iFC collection when service deployment, the related one or more iFC of each shared iFC collection indicate with unique identifier.
If HSS and S-CSCF support to share the function of iFC collection, so as S-CSCF during from HSS downloading service configuration data, can implicitly download by predefined unique shared iFC identifier and share the iFC collection, or not concrete iFC when promptly downloading, but from the S-CSCF local data base, search and obtain corresponding iFC set by this identifier that S-CSCF obtains by download, thereby can significantly reduce the data traffic of download interface, and and then can reduce taking of HSS/S-CSCF memory space, the capacity and the performance of raising system.
But the definition of this shared iFC collection is owing to the application of DSAI mechanism presents drawback.Normally, share the iFC collection and when service deployment, determine, when user's signing service, can dynamically not change.That is to say, as long as S-CSCF and HSS support to share the iFC collection, and HSS has disposed shared iFC collection when service deployment, the shared iFC collection that just must application during from HSS download user business configuration data have configured at S-CSCF so, and can not be dynamically according to actual state change share the iFC collection or selectivity is downloaded the iFC of shared iFC collection association.
Further, share between the associated iFC of associated iFC of iFC collection and DSAI and do not have necessary relation.That is to say that sharing the associated iFC of associated iFC of iFC collection and DSAI can be similar and different.Therefore, the iFC set of iFC collection association comprises or part comprises if the iFC of DSAI association set is shared simultaneously, summarily, exist overlapping between the associated iFC of the iFC set of shared iFC collection association and DSAI gathers, be that part iFC is simultaneously related with shared iFC collection and DSAI, must cause sharing iFC when DSAI is for unactivated state so and concentrate the iFC conductively-closed that is associated with DSAI.At this moment, share the iFC collection, will cause the iFC of conductively-closed to be downloaded improperly by HSS if when download user business configuration data, use.
In sum, the application of DSAI mechanism at present, might causing initial filter criteria correctly being downloaded, having influenced the application and the effect thereof of DSAI mechanism on the one hand by HSS owing to use sharing the iFC collection, on the other hand also remote-effects the application and the effect of shared iFC collection.
Summary of the invention
At above one or more problems, the invention provides a kind of initial filter criteria download and treatment system and method, can fully effectively utilize the definition optimization of sharing the iFC collection and download initial filter criteria, avoid simultaneously because the application of DSAI mechanism causes initial filter criteria to fail correctly to download.
In initial filter criteria download of the present invention and treatment system, call conversation control function entity and home subscriber server all support to share inceptive filtering rule set, this system comprises: the initial filter criteria setting device, be positioned at the user attaching server side, be used for the initial filter criteria enable list being set, with the state of activation of the initial filter criteria of representing to share the inceptive filtering rule set association in the business configuration data; And download and processing unit, be positioned at the service call session control function entity side, be used for from user attaching server downloading service configuration data, obtain the state of activation of the initial filter criteria of sharing the inceptive filtering rule set association according to the initial filter criteria enable list that is provided with in the business configuration data, and carry out subsequent treatment.

Embodiment
Below with reference to accompanying drawing, describe the specific embodiment of the present invention in detail.
Fig. 5 shows the block diagram according to initial filter criteria download of the present invention and treatment system.Wherein, call conversation control function entity and home subscriber server all support to share inceptive filtering rule set.As shown in Figure 5, this system comprises: initial filter criteria setting device 502, be positioned at the user attaching server side, be used for the initial filter criteria enable list being set, with the state of activation of the initial filter criteria of representing to share the inceptive filtering rule set association in the business configuration data; And download and processing unit 504, be positioned at the service call session control function entity side, be used for from user attaching server downloading service configuration data, obtain the state of activation of the initial filter criteria of sharing the inceptive filtering rule set association according to the initial filter criteria enable list that is provided with in the business configuration data, and carry out subsequent treatment.
Wherein, the initial filter criteria enable list is for sharing the subclass of inceptive filtering rule set.The initial filter criteria enable list comprises the state of activation of the initial filter criteria of initial filter criteria identifier and correspondence.Do not carry in sharing inceptive filtering rule set under the situation of initial filter criteria tabulation, all initial filter criteria that the inceptive filtering rule set association is shared in expression are state of activation.State of activation in the initial filter criteria enable list concrete initial filter criteria related with shared inceptive filtering rule set is corresponding one by one.State of activation in the initial filter criteria enable list concrete initial filter criteria related with shared inceptive filtering rule set is corresponding one by one according to putting in order.
Fig. 6 shows according to the processing filtering rule download of root invention and the flow chart of processing method.As shown in Figure 5, this method may further comprise the steps:
S602, all support to share under the situation of inceptive filtering rule set at service call session control function entity and user attaching server, the user attaching server is provided with the initial filter criteria enable list in the business configuration data, with the state of activation of the initial filter criteria of representing to share the inceptive filtering rule set association, and under the situation of needs with the business configuration transfer of data to service call session control function entity.
S604, the service call session control function entity side is from user attaching server downloading service configuration data, obtain the state of activation of the initial filter criteria of sharing the inceptive filtering rule set association according to the initial filter criteria enable list that is provided with in the business configuration data, and carry out subsequent treatment.
Wherein, the initial filter criteria enable list is for sharing the subclass of inceptive filtering rule set, and the initial filter criteria enable list comprises the state of activation of the initial filter criteria of initial filter criteria identifier and correspondence.Do not carry in sharing inceptive filtering rule set under the situation of initial filter criteria tabulation, all initial filter criteria that the inceptive filtering rule set association is shared in expression are state of activation.State of activation in the initial filter criteria enable list concrete initial filter criteria related with shared inceptive filtering rule set is corresponding one by one according to putting in order.
Usually, comprise the multiple network unit in the IMS network architecture, be not all unit all with context that the present invention discusses in relevant.Equally, below discuss and be limited to these unit, they are played a role in process of service execution, perhaps are in the purpose of describing exemplary embodiment of the present and the understanding of framework that service application general in the IMS network is triggered is very necessary.Framework that the service application that shows Fig. 1 triggers and related network element, interface, and the built-in function of each network element, trigger relevant network element with business and mainly comprise service call conversation control function (S-CSCF) 102, home subscriber server (HSS) 104 and application server (AS) 106.In HSS 104, deposit user's business configuration, comprising initial filter criteria (iFC).When the user registers, or when unregistered, receive SIP (Session Initial Protocol, when initial session protocol) asking, business configuration from HSS 104 download user, comprise initial filter criteria, and order is assessed filtering rule according to the service point in the conversation request, if the filtering rule that meets is arranged, the SIP request is sent to application corresponding server (AS) 106, provide Session Initiation Protocol processing, platform service to trigger and service logic, otherwise route requests to the destination via application server (AS) 106 by the default route rule.
Because the drawback that the application of DSAI mechanism presents the present invention proposes sharing the expansion that the iFC collection defines, promptly define a new subclass iFC enable list at the definition of sharing the iFC collection.HSS 104 if defined shared iFC collection, then can will share the state of activation notice S-CSCF 102 of the iFC of iFC collection association by the iFC enable list to the business configuration data of S-CSCF 102 download user the time.Whether S-CSCF 102 shares the concrete iFC of iFC collection association according to the local management policy lookup, and need to activate according to the iFC that the association of iFC collection is shared in the state of activation decision of iFC in the iFC enable list, and then preserves and need the iFC that activates.
Fig. 7, Fig. 8 a, and Fig. 8 b show two kinds of concrete definition modes of iFC enable list.As shown in Figure 7, share the iFC collection and can carry zero or an iFC enable list,, show that then all iFC that share the association of iFC collection are defaulted as activation if the iFC enable list does not carry.Further, the state of activation value of iFC enable list can be integer, and each bit of integer numerical value has been represented the state of activation of an iFC, 0 expression un-activation, and 1 expression activates.Effective number of bit has been represented total number of all iFC of shared iFC association, and the order of the iFC set of shared iFC collection association has been represented in the order strictness of each bit.As follows:
Share the related from left to right iFC order of iFC collection: iFC1, iFC2, iFC3 ... iFCn
State of activation indication order in the iFC enable list:
+++++++++++++++
Bit: 012 ... n
---------------------
IFC state of activation indication: iFC1|iFC2|iFC3| ... | iFCn
+++++++++++++++
This shows that bit 0 has been represented the state of activation of iFC1, bit 1 has been represented the state of activation of iFC2, by that analogy.This definition mode requires the iFC that shares the association of iFC collection to have strict order, be appreciated that different shared iFC collection if share the iFC set order difference of iFC collection association, promptly identical iFC has gathered by different sequential combination correspondences different shared iFC collection.S-CSCF 102 and HSS 104 are required to keep sharing the consistency of iFC collection data definition, not only require related iFC set content identical, also require the sequence consensus that iFC arranges in the set.
The advantage that the definition mode of this iFC enable list that Fig. 7 describes has is exactly to have described the state of activation of the iFC of shared iFC collection association by less data capacity, if it is big to share the iFC quantity of iFC collection association, advantage will be more obvious, and shortcoming is exactly that putting in order of associated iFC set had strict requirement.Fig. 8 a and Fig. 8 b have described the another kind of definition mode of iFC enable list.
Shown in Fig. 8 a, similarly, share the iFC collection and can carry zero or an iFC enable list, if the iFC enable list does not carry, show that then all iFC that share the association of iFC collection are defaulted as activation.Different with Fig. 7 is, the iFC enable list has comprised the state of activation group of the iFC of initial filter criteria (iFC) identifier and correspondence thereof, and the iFC enable list can carry the state of activation group of the iFC of zero or a plurality of initial filter criteria (iFC) identifier and correspondence thereof.Particularly, if the iFC enable list does not carry the state of activation group of the iFC of initial filter criteria (iFC) identifier and correspondence thereof, show that then all iFC that share the association of iFC collection are defaulted as activation; If the iFC enable list carries the state of activation group of the iFC of initial filter criteria (iFC) identifier and correspondence thereof, the number of group is total number of all iFC of shared iFC collection association.
Further, initial filter criteria (iFC) identifier is an integer, be used for unique identification iFC, when configuration iFC, generate, and download to S-CSCF102 by HSS 104 by Cx interface, the initial filter criteria assembly has been described in the business configuration class to the definition of initial filter criteria (iFC) identifier as Fig. 8 b.The state of activation of iFC is an enumeration type among Fig. 8 a, and the suggestion value is 0 (un-activation) and 1 (activation).
Similarly, the definition mode of Fig. 8 a and the described iFC enable list of Fig. 8 b, the definition mode of the iFC enable list of describing with respect to Fig. 7, maximum characteristics are exactly no longer to be concerned about to share putting in order of the associated iFC set of iFC collection, shortcoming has increased the definition to initial filter criteria (iFC) identifier exactly, volume of transmitted data strengthens, and is very little with respect to concrete iFC data downloaded transmission quantity certainly.
The definition of the iFC enable list that the present invention proposes also has favorable compatibility and flexibility.If it is state of activation that S-CSCF 102 nonrecognition iFC enable lists, S-CSCF 102 are defaulted as all iFC that share the association of iFC collection, promptly all relevant iFC all need to be saved and to be mated when receiving request message.Do not carry the iFC enable list if share iFC collection assembly in the business configuration, or the iFC enable list do not have the state of activation field, then the state of activation of iFC defaults to activation.
In sum, adopt the inventive method, when using DSAI mechanism, also can fully effectively utilize and share iFC collection download initial filter criteria, thereby reach the purpose that initial filter criteria optimization is downloaded.Meanwhile, new subclass iFC state of activation tabulation definition flexible configuration, easy to maintenance, can effectively avoid sharing the iFC that may cause after iFC collection and DSAI mechanism are used simultaneously by the problem of the incorrect download of HSS104.
Further be illustrated with application example of the present invention below.
Fig. 9 has described according to the embodiment of the invention and disposed new business in provider's network, and the high level block diagram of the method for iFC collection and DSAI is shared in configuration simultaneously.This method begins at step S902, receives request for new business at this provider's network, and this method then proceeds to step S904.
Step S904, the service code relevant with new service request are deployed in provider's network at least one application server, if or wish to share and be loaded on a plurality of application servers.This method then proceeds to step S906.
Step S906, the title of holding all application servers of this new business is stored among the HSS of provider's network.This method then proceeds to step S908.
Step S908, for this new business is distributed one or more unique DSAI-tag identifiers, and be deployed in provider HSS and hold in all application servers of this new business.Identify unique DSAI example that indicated by user ID and DSAI-tag.This method then proceeds to step S910.
Step S910, the relevant service configuration information of definition new business is for the formal parameter in the business configuration distributes default value.Meanwhile, the iFC collection is shared in definition, shares iFC and concentrates the state of activation of all related with it iFC to default to activation.This method then proceeds to step S912.
Step S912 defines the iFC related with the DSAI-tag identifier.This moment, the DSAI example did not generate because the user does not preengage.This method then proceeds to step S914.
Step S914, the user preengages new business.This method then proceeds to step S916.
Step S916, the specific actual parameter of use user provides the formal parameter in the business configuration, and the business information field of the business information assembly of this new business is provided.This moment, the DSAI example generated because the user preengages new business.This method then proceeds to step S918.
Step S918, the state of activation that is identified the DSAI of unique sign by user ID and DSAI-tag defaults to activation, and is kept among the HSS 104.Usually, the state of activation of DSAI can only be upgraded by Sh interface by AS 106, has reflected the multidate information of active user's signing service.At this moment, finish deployment, and disposed shared iFC collection and DSAI, so this method withdraws from new business.
In order better to illustrate, get back to Fig. 2.Fig. 2 shows the block diagram of professional trigger process in the call establishment.The network element that wherein relates to comprises service call conversation control function (S-CSCF) 202, home subscriber server (HSS) 204, application server 1 (AS1) 206 and application server 2 (AS2) 208, relevant interface comprises the Cx interface between S-CSCF202 and the HSS 204, Sh interface between AS 1206/AS2208 and the HSS 204, and the ISC interface between AS 12,06/,AS2 208 and the S-CSCF 202.
Suppose the user when the service deployment of Fig. 9,, generate two initial filter criteria X and Y as disposing call transfer service, respectively corresponding two kinds of different conditions, as call forward on busy and transfer on no reply, and handling the business of calling forward on busy by AS1 206, AS2 208 handles no-answer diversion operation base.Because S-CSCF 202 and HSS 204 all support to share the iFC collection, and when disposing call transfer service, HSS 204 has disposed shared iFC collection, share iFC collection related initial filter criteria X and related initial filter criteria Y simultaneously.Meanwhile, HSS204 has distributed two unique DSAI-tag identifiers, as DSAI-tag-1 and DSAI-tag-2, and related initial filter criteria X of difference and initial filter criteria Y.
When in the application server of user in provider's network during signing service, the multidate information of this business will be delivered among the HSS 204 by DSAI, and whether needs download to S-CSCF 202 to determine its related iFC by HSS 204 according to the state of activation information of DSAI.For example, Figure 10 has described according to one embodiment of present invention, is used for using the user in provider's network signing service, and according to the state of activation of DSAI the state of activation of iFC is set, thereby effectively utilizes the high level block diagram of the method for sharing the iFC collection.This method of Figure 10 starts from step S1002, in this user signing service in the application server in provider's network at first.This method then proceeds to step S1004.
Step S1004 disposes the state of activation value that this professional application server 1 (AS1) 206 is provided with by user ID and DSAI-tag-1 uniquely identified DSAI1.Suppose AS1206 deexcitation user's the business of calling forward on busy, the state of activation that DSAI1 is set is un-activation.This method then proceeds to step S1006.
Step S1006, the state of activation that application server 1 (AS1) 206 preserves the current DSAI1 among the HSS 204 by Sh interface to the HSS of user attaching 204 inquiries.This method then proceeds to step S1008.
Step S1008, AS1 206 inquires the state of activation that is kept at current DSAI1 among the HSS 204 and is activation, the state of activation of finding DSAI changes un-activation into by activation this moment, then upgrade the state of activation of DSAI1 to HSS 204 requests, AS1 206 upgrades the state of activation of DSAI1 for activating simultaneously.This method then proceeds to step S1010.
Step S1010, when HSS 204 receives from the state of activation message of the request renewal DSAI1 of AS1 206, retrieve all iFCs related and all related DSAI thereof, and the state of activation of iFC is set one by one according to the state of activation value of the state of activation value of current DSAI1 all DSAI related with iFC with DSAI1.Related initial filter criteria (iFC) X of DSAI1, as long as the state of activation of at least one DSAI of initial filter criteria (iFC) X association is for activating, the state of activation of initial filter criteria (iFC) X just is set to activate.Because the only related DSAI1 of initial filter criteria (iFC) X, and the state of activation of DSAI1 is un-activation, so the state of activation of initial filter criteria (iFC) X is set to un-activation.This method then proceeds to step S1012.
Step S1012, the state of activation value that HSS 204 preserves current DSAI1.This method then proceeds to step S1014.
Step S1014, because the user has disposed shared iFC collection, HSS 204 resets according to the state of activation of iFC and shares the iFC enable list information that iFC concentrates association in the business configuration.Because in step S1010, the active information of initial filter criteria (iFC) X is set to un-activation, and the active information of initial filter criteria (iFC) Y still keeps activating, therefore the information of iFC enable list description is 0,1, respectively corresponding initial filter criteria (iFC) X and initial filter criteria (iFC) Y.This method then proceeds to step S1016.
Step S1016 supposes that the user registers, and HSS 204 distributed S-CSCF 202 for the user registers, and HSS 204 is to S-CSCF 202 download user business configuration data, comprising shared iFC collection and subclass iFC enable list.This method then proceeds to step S1018.
Step S1018, S-CSCF 202 share iFC according to the local management policy lookup and concentrate related iFC, and whether concentrated related iFC state of activation information decision activates iFC and be kept among the S-CSCF 202 according to shared iFC.
If can discerning, S-CSCF 202 shares the subclass iFC enable list that iFC concentrates, then the iFC active information according to iFC enable list correspondence determines whether needs activate iFC, do not need to activate as initial filter criteria in this example (iFC) X, initial filter criteria (iFC) Y needs to activate.
If can discerning, S-CSCF 202 shares the subclass iFC enable list that iFC concentrates, but the iFC enable list does not carry or the iFC enable list in the state of activation field do not carry, then S-CSCF 202 is defaulted as and shares iFC to concentrate all related iFC be state of activation.
If the subclass iFC enable list that iFC concentrates is shared in S-CSCF 202 nonrecognition, then S-CSCF 202 is defaulted as and shares iFC to concentrate all related iFC be state of activation.
Typically, if the HSS explicitly is downloaded a complete iFC, the state of activation of this iFC is for activating.So this method has been finished the downloading process of shared iFC collection, withdraws from.
Get back to Fig. 2, when S-CSCF 202 receives SIP call request message 202, because initial filter criteria (iFC) X un-activation, S-CSCF 202 can matching initial filtering rule (iFC) X, therefore can not trigger the calling control to AS1 206 in this example.Relatively, because initial filter criteria (iFC) Y activates, 202 pairs of initial filter criteria of S-CSCF (iFC) Y mates, if the match is successful, S-CSCF 202 triggers the calling control to AS2 208.
The invention provides a kind of method that initial filter criteria optimization is downloaded and handled that is applied to be used in the IP Multimedia System (IMS).In other words, the invention provides the various embodiment of method, be used for fully to effectively utilize the definition optimization of sharing the iFC collection and download initial filter criteria at mobile IP network, avoid simultaneously because the application of DSAI mechanism causes initial filter criteria to fail correctly to download, and further guarantee the application and the effect thereof of DSAI mechanism.Although each embodiment of the present invention describes with reference to mobile IP network at this, specific embodiment of the present invention should not regarded as and limits the scope of the invention.Those skilled in the art is to be understood that and learns by aim of the present invention that design of the present invention can be applied in the network architecture of any IMS of utilization business basically.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
