Description
Technical field
The present invention relates to the mobile communication technology field, be meant that especially a kind of user carries out process registration to home signature user server (HSS).
Background technology
Development along with broadband network, mobile communication will not only be 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, by CSCF (CSCF) entity, MGCF (MGCF) entity, media resource function (MRF) entity and (HSS) etc. functional entity form.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 a customer data base, is used to store user's subscription data and configuration information etc.
CSCF can be divided into serving CSCF (S-CSCF), proxy CSCF (P-CSCF) and three logic entities of inquiry CSCF (I-CSCF) again.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.
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.
An IMS user (UE), after the physical connection of bottom carrying is set up, if the various application of using the IMS network to provide, will use the HSS of a public user identity in network of self to initiate register requirement, if this public user identity has passed through authentication and legitimate verification, then HSS will distribute a S-CSCF to serve for this UE, otherwise this user can not obtain any service that the IMS network provides.Registration has life cycle, and network is the each S-CSCF that distributes of certain user, only is responsible for handling in all IMS session signaling relevant with this UE of this period of registration, and specific implementation is referring to 3GPP TS 23.228 standards.
A user comprises a public user identity at least, and this public user identity is used for identifying user business to be asked.All public user identity of a user are registered respectively, the registration process that is each public user identity is independently, but because these public user identity all belong to same user, so stipulate in the standard, when certain user uses a public user identifier registration success, obtain network for behind the S-CSCF of its distribution, when this user used other public user identity to register, network must return same S-CSCF and use to the user.Promptly, think that promptly other public user identity of this user have also carried out recessive registration as long as this user's a public user identity is registered.
If this user has at least a public user identity once to register in HSS, and is in the term of validity, then the title of the S-CSCF that directly will be current serves for this user of HSS returns to I-CSCF;
If it is that cancel register or registration are expired that this user has the login state of a public user identity at least, but also preserve the title of the S-CSCF that this user used last time among the HSS, perhaps, this user when called once by network allocation a S-CSCF to come be its service, then HSS will return this for title of its S-CSCF that served to I-CSCF;
If the CAMEL-Subscription-Information content of this application registered UE in HSS carried out upgrading or upgrading, then HSS must give I-CSCF with this change notification, so HSS will return the capability set information of existing S-CSCF to I-CSCF, determine by I-CSCF whether the S-CSCF that distributes for the user before the user signing contract information upgrading can also continue as this user's service this moment, if S-CSCF in the past can't satisfy user after the upgrading to the demand of new business, then I-CSCF initiates reselecting S-CSCF according to the S-CSCF capability set information that obtains;
If this user was assigned with S-CSCF without any a public user identity, then HSS will only return the capability set of existing S-CSCF to I-CSCF, if this capability set is empty, show that I-CSCF can select any one S-CSCF, I-CSCF is according to the S-CSCF capability set information that obtains, initiate inquiry to HSS once more, explicitly call for HSS to return and satisfy the S-CSCF capability set information that the strictest signing service of user requires, initiate reselecting then S-CSCF.
Figure 1 shows that the flow chart of initiating to register based on IMS framework user of prior art.This flow chart is applicable to that the user initiates the relevant information that the public user identity of register requirement has not been preserved in HSS, the relevant information of perhaps preserving in HSS is expired, perhaps last time from registering expired and situation that hope refreshes between term of validity in order to prevent, this flow process is used the signaling control protocol of Session Initiation Protocol as IP multimedia session simultaneously, and the Cx interface between HSS and I-CSCF and HSS and the S-CSCF uses Diameter to transmit relevant information.
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, I-CSCF reselects S-CSCF with needs, and then 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;
Step 106, after HSS receives Cx-Select-Pull request message from I-CSCF, return the Cx-Select-Pull Resp message that comprises the S-CSCF capability set information that to support the strictest service contracting requirement of this application registered user to I-CSCF, comprise in this Cx-Select-Pull Resp message: the S-CSCF capability set information that can support the strictest service contracting requirement of this application registered user;
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;
According to CAMEL-Subscription-Information, if do not need the network topology hidden function, then the contact domain name of home network is resulting S-CSCF; Network topology hidden function if desired, then the contact domain name of home network is for realizing the I-CSCF of this function, be that P-CSCF is transmitted to the I-CSCF that realizes hidden function with all session signaling, the session signaling be transmitted to the contact domain name S-CSCF of home network by the I-CSCF of this execution network topology hidden function;
Do not need in the present embodiment to suppose the network topology hidden function, then I-CSCF sends Register message to this S-CSCF, comprise P-CSCF domain name or address in this Register message, public user identity, private user identity, the sign of P-CSCF place network, information such as the IP address of application for registration UE; When needs are realized the network topology hidden function, also comprise the information of the I-CSCF domain name that realizes hidden function in this message;
Step 109, after S-CSCF receives Cx-Put Resp from HSS, preserve title or the address of P-CSCF, and the information such as sign of P-CSCF place network, to be used for transmitting session signaling to UE, afterwards, S-CSCF sends the Cx-Pull request message to HSS, so that from the user signing contract information of HSS, download and professional relevant data, and wait for that HSS gives the Cx-Pull Resp message of returning, and comprises in this Cx-Pull message: public user identity, information such as private user identity, comprise in the Cx-PullResp message: user profile, and security information etc., user profile wherein is used for the user and is linked into the miscellaneous service controlling platform;
Step 111, S-CSCF returns 200OK message by I-CSCF and P-CSCF to UE.
So far, this user public user identity is finished registration.
There is following problem in above-mentioned user's register flow path: the triggering of above-mentioned steps 105 and step 106 is not cause entirely owing to information that HSS in the step 104 returns to I-CSCF, if promptly HSS only returns the information that comprises existing S-CSCF capability set to I-CSCF, then need to trigger step 105 and step 106, to obtain the information of the S-CSCF capability set that can support the strictest service contracting requirement of this application registered user.
And in the request message of step 105 and step 103, entrained information is basic identical, its unique difference is subscriber authorisation type information difference to some extent, but this difference only is the difference of type, 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 are redundant steps, and it has increased the load of interface between HSS and the I-CSCF.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of user to carry out process registration, optimized user's register flow path, and alleviated the load of interface between HSS and the I-CSCF to HSS.
For achieving the above object, technical scheme of the present invention is achieved in that
A kind of user carries out process registration to home signature user server, and this method may further comprise the steps:
After P-CSCF in a, accesses network receives registration Register message from the user, go out the address of home network access point I-CSCF according to the information analysis in this message, and to this I-CSCF transmission registration message, then, send Cx-Query message by the HSS of the I-CSCF that receives Register message in this home network;
B, HSS are according to the Cx-Query message that receives, return the response message Cx-Query Resp that comprises S-CSCF name and/or can support the S-CSCF capability set information of the strictest service contracting requirement of this application registered user to I-CSCF, determine final S-CSCF by I-CSCF according to the information of returning in the response message, and to this final S-CSCF transmission registration message, then, continue to carry out normal subsequent processing steps.
Preferably, this method further comprises: if the S-CSCF capability set information that can support the strictest service contracting of this application registered user to require that I-CSCF can not comprise from response message is selected S-CSCF, then return the message of registration failure and process ends to the user by P-CSCF.
Preferably, after the Cx-Query message that HSS receives, described step b further comprises: at first according to user's the CAMEL-Subscription-Information and the strategy of operator, judge whether to allow to initiate register requirement in the network of this UE under P-CSCF, if do not allow, directly return the message of registration failure by I-CSCF and P-CSCF, and process ends to the user, otherwise subsequent step again.
Preferably, if the title of the S-CSCF that promising this UE of HSS self preservation served, and the CAMEL-Subscription-Information content of this application registered UE in HSS carried out upgrading or upgrading, then step b is described is: HSS returns and is included as this UE S-CSCF name of serving and the response message that can support the S-CSCF capability set information that the strictest service contracting of this application registered user requires, and by I-CSCF after the final S-CSCF that determines sends registration message, continue to carry out normal subsequent processing steps.

Register flow path of the present invention is applicable to that the user initiates the relevant information that the public user identity of register requirement has not been preserved in HSS, the relevant information of perhaps preserving in HSS is expired, perhaps last time from registering expired and situation that hope refreshes between term of validity in order to prevent.
Figure 2 shows that and use flow chart of initiating to register of the present invention based on IMS framework user.In the present embodiment, use the signaling control protocol of Session Initiation Protocol as IP multimedia session, the Cx interface between HSS and I-CSCF and HSS and the S-CSCF uses Diameter to transmit relevant information.
Step 201, UE has set up after the physical connection of bottom carrying, and the P-CSCF under it in accesses network sends Register message, comprise in this message: public user identity, private user identity, home network domain name, and the information such as IP address of application for registration UE;
Step 202, receive the P-CSCF of Register message, home network domain name information in this message is resolved, to obtain the address of home network access point I-CSCF, the I-CSCF in home network transmits the Register message of UE then, comprises in the Register message of this forwarding: the title of P-CSCF or address, public user identity, private user identity, the sign of P-CSCF place accesses network, and the information such as IP address of application for registration UE;
Step 203, I-CSCF sends Cx-Query message to HSS, subscriber authorisation type (User-Authorization-Type) in this message is REGISTRATION, it shows it is a login request message, comprise in this Cx-Query message: public user identity, private user identity, and the information such as sign of P-CSCF place network;
Step 204, after HSS receives Cx-Query message from I-CSCF, at first according to user's the CAMEL-Subscription-Information and the strategy of operator, judge whether to allow to initiate register requirement in the network of this UE under P-CSCF, if do not allow, then directly return and comprise the response message Cx-Query Resp that refusal is accepted this log-on message, return the message of registration failure and process ends by P-CSCF to the user by I-CSCF again to I-CSCF;
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 205;
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 directly returns the Cx-Query Resp of the S-CSCF capability set information that comprises S-CSCF name and can support the strictest service contracting requirement of this application registered user to I-CSCF, execution in step 205;
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 also returns the Cx-Query Resp that comprises the S-CSCF capability set information that can support the strictest service contracting requirement of this application registered user to I-CSCF, execution in step 205;
Step 205, I-CSCF carries out domain name mapping according to the title of the S-CSCF that HSS returns, perhaps, carries out domain name mapping according to the title of the S-CSCF that obtains in the S-CSCF capability set information that can support the strictest service contracting requirement of this application registered user, thereby obtain the address of S-CSCF
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;
According to CAMEL-Subscription-Information, if do not need the network topology hidden function, then the contact domain name of home network is resulting S-CSCF; Network topology hidden function if desired, then the contact domain name of home network is for realizing the I-CSCF of this function, be that P-CSCF is transmitted to the I-CSCF that realizes hidden function with all session signaling, the session signaling be transmitted to the contact domain name S-CSCF of home network by the I-CSCF of this execution network topology hidden function;
Do not need in the present embodiment to suppose the network topology hidden function, then I-CSCF sends Register message to this S-CSCF, comprise P-CSCF domain name or address in this Register message, public user identity, private user identity, the sign of P-CSCF place network, information such as the IP address of application for registration UE; When needs are realized the network topology hidden function, also comprise the information of the I-CSCF domain name that realizes hidden function in this message;
Step 206, S-CSCF sends Cx-Put message to HSS, and wait for that HSS returns the Cx-Put Resp response message that comprises confirmation, 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, private user identity, information such as S-CSCF name;
Step 207, after S-CSCF receives Cx-Put Resp from HSS, preserve title or the address of P-CSCF, and the information such as sign of P-CSCF place network, to be used for transmitting session signaling to UE, afterwards, S-CSCF sends the Cx-Pull request message to HSS, so that from the user signing contract information of HSS, download and professional relevant data, and wait for that HSS gives the Cx-Pull Resp message of returning, and comprises in this Cx-Pull message: public user identity, information such as private user identity, comprise in the Cx-PullResp message: user profile, and security information etc., user profile wherein is used for the user and is linked into the miscellaneous service controlling platform;
Step 208, S-CSCF sends to relevant professional controlling platform with log-on message and carries out suitable professional control flow according to the filtering rule that obtains from user profile;
Step 209, S-CSCF returns 200OK message by I-CSCF and P-CSCF to UE.
So far, this user public user identity is finished registration.
