Abstract
The present invention discloses an implementation method and a device of a so-called unregistered service. A called side I-CSCF receives a call request message sent by a calling subscriber, and sends the request message for the HSS of a called subscriber to inquire about an S-CSCF assigned to the called subscriber, the S-CSCF is selected according to a message returned by the HSS and the call request message is forwarded to the selected S-CSCF; the S-CSCF receives the call request message and determines the subscription data of the called subscriber unsaved by self, the request message is sent to the HSS to download the subscription data of the called subscriber; the HSS returns the subscription data through a response message and keeps that the status of the called subscriber is not registered; the S-CSCF triggers an AS according to the subscription data returned by the HSS. Therefore, the present invention ensures the consistency of the HSS and the S-CSCF data with minimum message quantity under the condition of S-CSCF not saving the unregistered subscriber data, and the operating efficiency of a system is improved.
Description
Technical field
The present invention relates to IMS is the implementation of non-login service in the IP Multimedia System network, relates in particular to a kind of implementation method and device thereof of called non-login service.
Background technology
Two core nodes are arranged: home signature user server (HSS) and service call conversation control function (S-CSCF) in the 3GPP standardization IP Multimedia System structure.Home signature user server is the central database of storing subscriber information, and it comprises all and user-dependent positional information, security information (comprising authentication and authorization message), subscriber information message (comprising the service that the user orders) and distributes to the information etc. of user's S-CSCF.Signaling-information among CSCF (CSCF) the main processing IMS mainly comprises three types: query call conversation control function (I-CSCF), S-CSCF, Proxy Call Session Control Function (P-CSCF).Wherein, S-CSCF is a Centroid of carrying out session control.
At present, agreement has stipulated that user's login state comprises: unregistered (Not Register) shows that the user is unregistered and do not distribute S-CSCF; Authentication unsettled (Authentication Pending) shows that the user is in the intermediateness of authentication process and distribution S-CSCF is arranged; Registered (Register) shows that the user has registered and distribution S-CSCF arranged; Non-registered (Unregistered) shows that the user is unregistered but distributed S-CSCF.The Unregistered state mainly has non-login service and is set up when being called out in that the user is signatory, and S-CSCF keeps user contracting data when user log off also can be in this state.
The call flow of signaling plane is initiated initial Invite request beginning from the calling subscriber; From the Calling Side home network to the callee side home network; If the state before the called subscriber calls out is unregistered (Not Register) and not signatory non-login service, then the callee side home network can be because of there not being called subscriber's subscription data to return failure response; If the state of called subscriber before calling out is unregistered (Not Register) but the non-login service of having contracted, the callee side home network will continue to download called subscription data, and it is professional to trigger corresponding called, and whole called non-login service flow process is as shown in Figure 1.
The flow chart of the implementation method of called non-login service when Fig. 1 does not preserve the nonregistered user subscription data for S-CSCF in the prior art may further comprise the steps:
Step 101, the calling subscriber initiates the Invite request, is sent to callee side home domain I-CSCF, and request header carries called subscriber's public identify (IMS Public Identity);
Step 102, according to user's public identify, I-CSCF sends place information inquiry request LIR to HSS, is used for inquiring about name or the ability of the S-CSCF that the called subscriber assigns;
Step 103, because this moment, called login state was Not Register, and the non-login service of having contracted, HSS will send place information inquiry response LIA, be used for returning assigning and give called S-CSCF name or ability, and at this moment return code is DIAMETER_SUCCESS; HSS also possibly not return S-CSCF ability (at this moment also not having the S-CSCF name), and at this moment return code is DIAMETER_UNREGISTERED_SERVICE;
Step 104 is selected suitable S-CSCF to top two kinds of situation I-CSCF according to S-CSCF name or ability that HSS returns, perhaps optional S-CSCF;
Step 105, I-CSCF transmits Invite and asks to this territory S-CSCF;
Step 106; Because the signatory non-login service of called subscriber; S-CSCF does not have user contracting data; So S-SCSF need initiate registration/notice of cancellation request (SAR) message of Server Assignment Type value for " UNREGISTERED_USER ", to download user data and to notify HSS to distribute to the name of called subscriber's S-CSCF;
Step 107; HSS returns registration/notice of cancellation response (SAA) message, and return code is DIAMETER_SUCCESS, shows that the last called subscriber's of HSS this moment state has been Unregistered State; Assigned S-SCSF, and S-CSCF has downloaded user contracting data;
After the called non-login service flow process finishes; S-CSCF can select not preserve user contracting data; Then need change user's among the HSS login state; Otherwise the data that can cause HSS and S-CSCF are inconsistent, and promptly last this user of S-CSCF is unregistered (Not Register), and last this user of HSS is non-registered (Unregistered); The inconsistent failure that will cause subsequent operation inevitably of this status data; For example HSS can return failure because of S-CSCF user data of no use to PPR (Push-Profile-Request) request that S-CSCF initiates the RTR (Registration-Termination-Request) that nullifies and revises user contracting data; And this Client-initiated logout flow path also can can't be nullified non-registered (Unregistered) state of the user among the HSS because of S-CSCF user data of no use;
Step 108; Feasible method is at present; S-CSCF initiation value is the SAR request for the registration/notice of cancellation request of " ADMINISTRATIVE_DEREGISTRATION "; To change the login state that HSS goes up the user, definite saying is exactly that login state is become unregistered (Not Register) from non-registered (Unregistered), and removes the name of the S-CSCF that distributes;
Step 109, it is the SAA response that HSS returns registration/notice of cancellation response, the name of not preserving S-CSCF does not change user unregistered (Not Register) state;
Step 110, according to the result that HSS returns, S-CSCF carries out corresponding triggering application server (AS) or returns error code;
Step 111, S-CSCF carries out other operations.
Because S-CSCF do not preserve the nonregistered user subscription data, so S-CSCF user's login state is unregistered (Not Register), in order to guarantee the consistency of same user registration state on S-CSCF and HSS; Produce the message process of double SAR/SAA between S-CSCF and the HSS; User Status changes to non-registered (Unregistered) from unregistered (Not Register), changes to unregistered (Not Register) from non-registered (Unregistered) again, and operation seems redundant on the one hand; Increase CSCF and HSS and handled burden; Influenced running efficiency of system, on the other hand, life period is poor between two SAR message that S-CSCF sends; The last process that exists User Status to switch of HSS possibly brought unnecessary operation hidden danger.
Summary of the invention
The technical problem that the present invention will solve provides a kind of implementation method and device thereof of called non-login service, has simplified the implementation procedure of non-login service, makes it to improve more with rationally.
On the one hand, the present invention proposes a kind of implementation method of called non-login service, may further comprise the steps:

Steps A 2, said second type of Control Node are received call request message and are confirmed itself not preserve called subscriber's subscription data, send a request message to said HSS and download called subscriber's subscription data;
Steps A 3, said HSS returns subscription data through response message and keeps called subscriber's state is unregistered Not Register state;
Steps A 4, said second type of Control Node triggers application server according to the subscription data that said HSS returns.
In the said method, the request message that sends to HSS described in the steps A 2 is a registration/notice of cancellation request SAR message, and response message described in the steps A 3 is a registration/notice of cancellation response SAA message.
In the said method, steps A 3 further may further comprise the steps:
Steps A 31, when the IP multimedia pUblic identity Public-Identity in the said HSS inspection SAR message and definite respective user are not limited to communicate by letter, the service assigns type Server-Assignment-Type in the inspection SAR message;
Steps A 32 when Server-Assignment-Type is UNREGISTERED_USER_NOT_STORE_SERVER_NAME, judges whether the login state of Public-Identity respective user is unregistered state;
Steps A 33, if said user's login state is unregistered, the Result-code value is DIAMETER_SUCCESS in the SAA message of then returning; Otherwise the Resultcode value is DIAMETER_ERROR_IN_AS_SIGNMENT_TYPE in the SAA message of returning.
In the said method, steps A 4 further may further comprise the steps:
Steps A 41, the Result-Code value in the inspection SAA message;
Steps A 42; If the Result-Code value is DIAMETER_ERROR_IN_ASSIGNMENT_TYPE; Said second type of Control Node returned failure response message, if the Result-Code value is DIAMETER_SUCCESS, said second type of Control Node judges whether said call request message satisfies the signatory trigger condition of user; If satisfy condition, then trigger application server.
In the said method, steps A 1 further may further comprise the steps:
When steps A 11, callee side first kind Control Node are received the Invite request message that the calling subscriber sends, send place information inquiry request LIR message to called subscriber's HSS;
Steps A 12; Said HSS confirms that called subscriber's login state is unregistered and called subscriber's non-login service of having contracted; And send place information inquiry response LIA message, said LIA message is carried S-CSCF name or ability or is not carried S-CSCF ability and name;
Steps A 13; If LIA carries the name or the ability of assigning second type of Control Node of giving the called subscriber; Then first kind Control Node is selected second type of Control Node according to the name or the ability of said second type of Control Node; If LIA does not carry the name and the ability of second type of Control Node, then first kind Control Node is selected second type of Control Node arbitrarily;
Steps A 14, first kind Control Node is transmitted the Invite request message and is given selected second type of Control Node.

Embodiment
The present invention is directed to the situation that signatory non-login service of called subscriber and S-CSCF do not preserve the user data of non-login service; Proposed more perfect called non-login service implementation, main thought is to make HSS support S-CSCF to go up the extension process of service assigns type (Server-Assignment-Type) AVP value for " UNREGISTERED_USER_NOT_STORE_SERVER_NAME ".
Fig. 2 is the flow chart of the implementation method of the described called non-login service of one embodiment of the invention.
Specifically describe as follows:
Step 201, callee side I-CSCF receives the Invite call request message that the calling subscriber sends;
Step 202, I-CSCF sends place information inquiry request LIR to HSS, is used for inquiring about name or the ability of the S-CSCF that the called subscriber assigns;
Step 203, HSS sends place information inquiry response LIA, and this message is returned S-CSCF name or ability or is not returned S-CSCF ability (at this moment also not having the S-CSCF name), does not return optional S-CSCF of LIA message indication I-CSCF of S-CSCF ability;
Step 204, I-CSCF selects suitable S-CSCF according to S-CSCF name or ability that HSS returns, perhaps optional S-CSCF;
Step 205, I-CSCF transmits the Invite request message and gives callee side S-CSCF;
Step 206 after callee side S-CSCF receives the Invite call request message of non-registered users, is sent SAR, download user data to HSS.Because S-CSCF does not support to preserve the non-registered users data, so send SAR message to HSS, wherein the type of Server-Assignment-Type AVP is UNREGISTERED_USER_NOT_STORE_SERVER_NAME;
Callee side S-CSCF receives Invite message; Check at first whether the Request URI (indication called subscriber's public identify) in the message is limited to carry out IMS communication; But find not this user's public identify; Need the download user subscription data, carry out registration/notice of cancellation flow process (SAR/SAA); If before carrying out registration/notice of cancellation flow process, be necessary to carry out the process of inquiry HSS, that is to say to exist under the situation of a plurality of HSS that S-CSCF selects the HSS at user data place through inquiry Subscription Locator Function (SLF); S-CSCF is as shown in table 1 to the structure of registration/notice of cancellation request (SAR) message that HSS sends:
Request terms | Corresponding DiameterAVP | Optional | Describe |
IP multimedia pUblic identity | Public-Identity | Condition | Because do not have the privately owned sign of nonregistered user, this field must occur |
The name of S-CSCF | Server-Name | Essential | The name of S-CSCF |
IP multimedia private identity | User-Name | Condition | The privately owned sign that does not have nonregistered user |
The service assigns type | Server-Assignment-Type | Essential | Need be in 3GPP TS 29.229 expansion type UNREGISTERED_USER_NOT_STORE_SERVER_NAME |
Whether user data exists | User-Data-A1ready-Available | Essential | There are not the nonregistered user data, so be USER_DATA_NOT_AVAILABLE (0) |
Routing iinformation | Destination-Host | Condition | This field of nonregistered user should not occur |
Table 1:S-CSCF registration/notice of cancellation request (SAR)
Type to Server-Assignment-Type AVP in the 29229V7.5.0 agreement is expanded; Increase types value UNREGISTERED_USER_NOT_STORE_SERVER_NAME (12); Be used for downloading the nonregistered user data, and the maintenance User Status is unregistered (Not Register) on HSS to the HSS request.
Fig. 3 illustrates the composition structure of the S-CSCF that is used to carry out above-mentioned processing.This S-CSCF comprises message sink detecting unit, User Status judging unit and request message generation unit, wherein:
The message sink detecting unit is used to detect the message that receives and when detecting the Invite request, notifies the User Status judging unit;
The User Status judging unit; The Invite that is used for sending according to the message sink detecting unit asks called subscriber's public identify to judge local this user's the subscription data of whether preserving; And when confirming this user's not subscription data the notification request message generation unit
The request message generation unit is used to generate to this user's HSS request download user subscription data and to indicate this HSS to keep this user registration state be the SAR message of unregistered (Not Register).
Step 207, HSS returns subscription data, but does not preserve the name of S-CSCF, does not change user unregistered (Not Register) state;
The structure of the registration that HSS returns to S-CSCF/notice of cancellation response (SAA) message is as shown in table 2:
Response item | Corresponding DiameterAVP | Optional | Describe |
IP multimedia private identity | User-Name | Condition | Only if do not have this IP multimedia private identity among the HSS, otherwise this field should occur |
Return code | Result-Code/Experimental-Result | Essential | The possible return value of Result-Code AVP has DIAMETER_SUCCESSDIAMETER_ERROR_USER_NKNOWNDIAMETER_AUTHO RIZATION_REJECTEDDIAMETER_ERROR_IN_ASSIGNMENT_TYPE |
User property | User-Data | Condition | S-CSCF user data of no use, this field are carried the signatory attribute of these all implicitly registered set of user |
Charge information | Charging-Information | Condition | This field should occur when user property was arranged |
Relevant privately owned sign | Associated-Identities | Optional | Return in the IMS territory all with SAR in the signatory related privately owned sign of total sign, if having only a privately owned sign, then this field should not occur |
Table 2:S-CSCF registration/notice of cancellation response (SAA)
The concrete processing logic of HSS is as shown in Figure 4, and idiographic flow is following:
Step S41, the IP multimedia pUblic identity (Public-Identity) in the inspection SAR message, if the user does not exist, then processing execution step S42 carries out IMS communication if the user is promptly limited by bared, processing execution step S43 then, otherwise, processing execution step 404;
Step S42, return results code (Result-Code) value is DIAMETER_ERROR_USER_UNKNOWN, processing finishes;
Step S43, return results code (Result-Code) value is DIAMETERAUTHORIZATION_REJECTED, processing finishes;
Step S44; Check out when service assigns type (Server-Assignment-Type) in the SAR message is UNREGISTERED_USER_NOT_STORE_SERVER_NAME; If the login state of Public-Identity is unregistered state (Not Register states) among the SAR; Processing execution step S45 then, otherwise, processing execution step S46;
Step S45, the Result-code value of returning SAA is DIAMETER_SUCCESS, processing finishes;
Step S46, the Result-code value of returning SAA is DIAMETER_ERROR_IN_ASSIGNMENT_TYPE, processing finishes.
Need to prove that at this when having only Result code value for DIAMETER_SUCCESS, return user property and charge information, user property comprises the signatory attribute of all implicitly registered set of Public-Identity in the SAR message.If the signatory related a plurality of privately owned signs of the Public-Identity in the SAR message, then these privately owned signs should be returned in the Associated-Identities field in SAA.
Fig. 5 illustrates the composition structure of the HSS that is used to carry out above-mentioned processing logic.This HSS comprises message sink detecting unit, User Status processing unit and response message generation unit, wherein:
The message sink detecting unit; Be used for detecting SAR message that S-CSCF sends and when detecting SAR message and comprise request download user subscription data and indicate this user registration state to remain the information of unregistered state (Not Register states), notice User Status processing unit and response message generation unit;
The User Status processing unit, being used to keep this user registration state is unregistered state (NotRegister states);
The response message generation unit is used to generate the SAA message of carrying this user contracting data.
Step 208, according to the result that HSS returns, S-CSCF carry out corresponding triggering application server (Application Server, AS) or return error code, processing logic is as shown in Figure 6, idiographic flow is following:
Step S61; Result-Code value among the S-CSCF inspection SAA, if the Result-Code value is DIAMETER_AUTHORIZATION_REJECTED or DIAMETER_ERROR_USER_UNKNOWN, processing execution step S62 then; If the Result-Code value is DIAMETER_ERROR_IN_ASSIGNMENT_TYPE; Processing execution step S63 then, if the Result-Code value is DIAMETER_SUCCESS, processing execution step S64 then;
Step S62, S-CSCF returns failure response, and processing finishes;
Step S63, S-CSCF returns failure response, and processing finishes;
Step S64 checks whether this initial Invite request satisfies the signatory trigger condition of user, if satisfy condition; Then insert the Route field, be worth URI, ask for Invite for AS; S-CSCF preserves the call parameter that is used to discharge session; Like the Contact in the message, CSeq and Record-Route, and carry out and trigger flow process, processing finishes.
Here need to prove that when whether inspection Invite request satisfied the signatory trigger condition of user, according to user contracting data, according to priority trigger condition was relatively step by step relatively accomplished up to all.If there is not the AS of triggering, then return failure response, stop the callee side calling procedure.
Contrast with prior art; S-CSCF does not preserve the state of nonregistered user; Only initiate a Server Assignment Type value to HSS this moment is the SAR message of " UNREGISTERED_USER_NOT_STORE_SERVER_NAME ", and user registration state is unregistered (Not Register) among download user data and the maintenance HSS; Because HSS goes up User Status and does not change, and does not have the inconsistent hidden danger of data; And the message process of original twice SAR/SAA is merged into once, improved running efficiency of system.
In sum, adopt and should invention download the non-login service user contracting data, compatible S-CSCF does not preserve the realization scene of nonregistered user data, has guaranteed the consistency of HSS and S-CSCF data simultaneously with minimum message count.
