Description
Technical field
The present invention relates to the mobile communication technology field, be meant a kind of method that alleviates home signature user server (HSS) interface load especially.
Background technology
Development along with broadband network, mobile communication not only is confined to traditional Speech Communication, by with present that business (presence), short message, webpage (WEB) are browsed, the combining of data service such as locating information, propelling movement business (PUSH) and file-sharing, mobile communication can realize the business of multiple medium types such as audio frequency, video, picture and text, to satisfy user's multiple demand.
For example, short message service can provide the service of instant message, chatroom and multimedia short message; Video traffic can provide amusement, multimedia messages service such as to exchange with daily; Electronic commerce affair can provide services such as catalogue, search engine, shopping cart, order management and payment; Game service can provide services such as solitaire game and group's recreation; Positioning service can provide services such as missing, guide and warning; The personal assistant business can provide services such as address book, schedule, bookmark management, file storage, event notification and Email.
Under the promotion of multiple application, 3rd Generation Partnership Project (3GPP) and 3rd Generation Partnership Project 2 (3GPP2) etc. are organized and have all successively been released IP-based IP multimedia subsystem, IMS (IMS) framework, its objective is and in the mobile network, use a kind of standardized open architecture to realize diversified multimedia application, so that more selection and abundanter impression to be provided to the user.
The IMS framework is superimposed upon on the packet field network, is made up of functional entitys such as CSCF (CSCF) entity, MGCF (MGCF) entity, media resource function (MRF) entity and HSS.
CSCF can be divided into serving CSCF (S-CSCF), proxy CSCF (P-CSCF) and three logic entities of inquiry CSCF (I-CSCF) again, and these three logic entities may be on the different physical equipment, also may be functional modules different in the same physical equipment.S-CSCF is the service switching center of IMS, is used to carry out session control, peace preservation association's speech phase, and managing user information produces charge information etc.; P-CSCF is the access point of terminal user access to IMS, is used to finish user's registration, service quality (QoS) control and safety management etc.; I-CSCF is responsible for the intercommunication between the IMS territory, and network topology structure and configuration information are externally hidden in the distribution of management S-CSCF, and produce metering data etc.
MGCF is used to realize the intercommunication of IMS network and other network; MRF is used to provide media resource, as the folding and unfolding sound, and encoding and decoding and multimedia conferencing bridge etc.
HSS is very important customer data base, storage user's subscription data information and configuration information etc.; Sign, numbering and addressing information as the user; User's security information; User position information and user's descriptor (user profile information) etc.HSS is used to support the processing of each network entity to calling and session.One or an above HSS are arranged in the home network, and the concrete quantity of HSS depends on mobile contracted user's quantity, the capacity of the network equipment and concrete networking situation.
IMS network architecture by the 3GPP definition is equally applicable to the packet network that 3GPP2 defines, i.e. the terminal type of the realization of IMS and user use is irrelevant, and therefore, this IMS is not limited to only be applied in the network relevant with 3GPP and uses.
Be example with the flow process of initiating for the first time to register based on the public user identity of IMS framework below, specify the reciprocal process between HSS and the network entity.
The public user identity based on the IMS framework that Figure 1 shows that prior art is initiated the flow chart registered for the first time.In the present embodiment, use the signaling control protocol of Session Initiation Protocol as IP multimedia session, Cx interface use Diameter between HSS and I-CSCF and HSS and the S-CSCF transmits relevant information, and does not need the network topology hidden function in the present embodiment.
Otherwise HSS judges the title of self whether preserving the S-CSCF that promising this UE served, and whether this request registration user's who self preserves signed instrument content take place to upgrade or upgrading,
If the title of the S-CSCF that promising this UE of HSS self preservation served, and this request registration user's that self preserves signed instrument content does not take place to upgrade or upgrading, after then HSS returns the Cx-Query Resp that comprises S-CSCF name to I-CSCF, execution in step 107;
If the title of the S-CSCF that promising this UE of HSS self preservation served, and this request registration user's that self preserves signed instrument content has taken place to upgrade or upgrading, after then HSS returns the Cx-Query Resp that comprises S-CSCF name and existing S-CSCF capability set information to I-CSCF, judge further by I-CSCF whether the S-CSCF name that returns is available, if can use, then execution in step 107, otherwise, execution in step 105;
If the title of the S-CSCF that served for this UE that HSS self has not distributed, and this request registration user's that self preserves signed instrument content has taken place to upgrade or upgrading, after then HSS only returns the Cx-Query Resp that comprises existing S-CSCF capability set information to I-CSCF, execution in step 105;
If I-CSCF can't according to can support the strictest service contracting requirement of this application registered user capability set information obtain a new S-CSCF, then I-CSCF returns the message of registration failure and process ends by P-CSCF to the user;
Step 108, S-CSCF sends Cx-Put message to HSS so that HSS preserves the title of the S-CSCF that is used for this user, wherein this Cx-Put message comprises: public user identity and or private user identity, information such as S-CSCF name;
Step 109, HSS returns Cx-Put Resp response message, shows that it has preserved the name information of this S-CSCF;
Step 110 after S-CSCF receives Cx-Put Resp from HSS, sends Cx-Pull request message, acquisition request user signing contract information to HSS; Comprise in this Cx-Pull message: public user identity and or information such as private user identity;
Step 111, HSS according to public user identity and or private user identity inquire about, and return the Cx-Pull Resp message that comprises user signing contract information to S-CSCF, promptly comprise in this Cx-Pull Resp message: user description information, and security information etc., user description information wherein is used for the user and is linked into the miscellaneous service controlling platform;
So far, this user public user identity is finished registration for the first time.
In above-mentioned flow process, the effect of Cx-Put message is the title that request HSS saves as the S-CSCF of user's service in the step 108, and Cx-Put Resp message only shows the affirmation to above-mentioned request message in the step 109; The effect of Cx-Pu1l message is that the CAMEL-Subscription-Information that the Cx-Pull Resp of step 111 is only the user sends to S-CSCF to the required user signing contract information of HSS request subsequent treatment in the step 110.
User description information is kept among the HSS, is static relatively user profile, for the information such as S-CSCF name of this user's service then along with calling out and the carrying out of session changes, be the user profile of relative dynamic.By above-mentioned analysis as can be seen, user signing contract information among the HSS can not change because this HSS receives certain S-CSCF name information, and in existing the realization, HSS will preserve information and returns user signing contract information to S-CSCF and realize that with two message it has increased the load of Cx interface between HSS and the S-CSCF the affirmation of S-CSCF name.
In addition, in the request message of the step 105 of above-mentioned flow process and step 103, entrained information is identical, it does not bring HSS any new information, similarly, in step 106, the information that HSS returned is not returned more more valuable information to I-CSCF yet.According to above-mentioned analysis as can be seen, step 105 and step 106 also are redundant steps, and it has increased the load of Cx interface between HSS and the I-CSCF equally.
Though above-mentioned analysis is carried out the process of registration for the first time based on user's public user identity, but carrying out the non-registration first time and IMS user at user's public user identity carries out session etc. all relates to flow process to HSS inquiring user CAMEL-Subscription-Information, in the flow process of inquiring about S-CSCF, all there is this problem.
