Volume method and device.
Background technology
IP Multimedia System (IP Multimedia Subsystem, IMS) register flow path occurs in multiple field
Under scape, initial registration, cancellation and periodic registration refresh, change registration, re-injection that access point causes
Volume, all can initiate register flow path.In IMS registration flow process, relate to subscriber equipment (User Equipment,
UE), agent call conversation control entity (Proxy-CSCF, P-CSCF), query call session control are in fact
Body (Interrogating-CSCF, I-CSCF), service call conversation control entity (Serving-CSCF,
S-CSCF) and ownership place subscription data service (Home Subscriber Server, HSS), application clothes
Signalling exchange between business device (Application Server, AS).Wherein, in the multiple subprocess comprised,
Multimedia authentication request between S-CSCF and HSS (Multimedia-Authentication-Request,
MAR), multimedia authentication responses (Multimedia-Authentication-Answer, MAA) subprocess,
And service assignment request (Server Assignment Request, SAR) between S-CSCF and HSS,
Service distribution response (Server Assignment Answer, SAA) subprocess, third-party registration subprocess
It is all therein to relate to the process that amount of calculation is bigger, elapsed time is relatively more.
And the behavior of user cannot retrain.User may be regular be unregistered, carry out the most again
Registration.Particularly when air interface signals instability or network transfer delay, owing to wanting in registration process
Taking the time that comparison is many, user may nullify and repeat registration afterwards.Or, because be manually set
Reason, after nullifying, registers after certain interval of time again.Nullify frequently and in registration process,
HSS and S-CSCF to carry out the calculating of authentication vector repeatedly, user data and the reading of configuration information
Go out and write, and third-party registration.Cause registration and unregistration flow process all can take considerable time, from
And causing Consumer's Experience to decline, network operations and Signalling exchange load increase the weight of.Especially in great amount of terminals simultaneously
When sending registration request, can be formed in registration message flow set and send, owing to IMS core net has little time to process
These messages, cause message repeatedly to retransmit so that the pressure of whole network is increasing, so that IMS
Core net cannot be born.
IMS log off procedure and IMS registration process are relatively independent processes.Particularly, in log off procedure,
After cancellation completes, S-CSCF by the safe context of corresponding UE, configuration information and user profile,
Will delete.Send 200OK(at S-CSCF to I-CSCF to agree to) after, S-CSCF is permissible
Initiate third party's log off procedure at once, the information of UE in AS is set to unregistered state.Again registering
Cheng Zhong, S-CSCF can ask for the safe context related datas such as authentication vector again to HSS；Logical in authentication
Later, configure and the information of user to HSS write and acquisition；And in registration final stage, initiate to AS
The third party logon procedure.
In sum, the third party logon procedure is an important component part of whole registration process.S-CSCF
The demand initiating multiple the third party logon procedure to meet user may be needed.And for a user, it is signed
About AS changes not quite in registration process repeatedly.Cancellation at short notice and be registered in reality and be
The most common, and prior art is the most comparatively laborious for the process of this situation, causes user's perception to decline.

Stop third party's log off procedure intervalometer corresponding for described UE；
S203, described S-CSCF send for representing the registration request accepting described UE to I-CSCF
After confirming message, check whether and carried out third party's log off procedure for this UE, if it is, to application
Server A S initiates the third party logon procedure for this UE；Otherwise, the last time the 3rd to this UE
The old AS list of side's registration process is entered with the new AS list of the third party logon procedure of currently this UE
Row compares；
S204, described S-CSCF according to comparative result, initiate the third party logon procedure for this UE or
Third party's log off procedure.
It is preferred that described S-CSCF is according to comparative result, initiate the third party logon procedure for this UE
Or third party's log off procedure, including:
If old AS list and new AS list are not quite identical, for new AS list comprises
But the AS, S-CSCF that do not comprise in old AS list initiate the third party logon procedure for this UE；
The AS, S-CSCF that for comprising in old AS list but do not comprise in new AS list initiate for
Third party's log off procedure of this UE.
If it is preferred that old AS list and new AS list are not quite identical, for new AS row
The AS, S-CSCF that table is identical with in old AS list no longer initiates the third-party registration mistake for this UE
Journey.
If it is preferred that old AS list and new AS list are completely the same, the most described S-CSCF ties
The registration process of Shu Dangqian, no longer initiates the third party logon procedure for this UE.
Seeing Fig. 3, in the embodiment of the present invention, the step of the logout flow path of IMS is as follows:
Step 501, UE sends registration (REGISTER) request message to P-CSCF.This registration please
Ask message the same with the situation of re-register process, but instruction in time-out terminates head (Expires header)
Value be 0.This request is addressed to P-CSCF during UE initial registration.
Step 502, P-CSCF removes safety-related information, and registration (REGISTER) request is disappeared
Breath is forwarded to I-CSCF.
Step 503, I-CSCF then can contact HSS, sends Cx inquiry (Cx-Query) to HSS and disappears
Breath, to inquire about the address of S-CSCF.
Step 504, HSS passes through Cx inquiry response (Cx-Query the S-CSCF address chosen
Response) message issues I-CSCF.
Step 505, I-CSCF is transmitted to REGISTER request the S-CSCF selected.
S-CSCF can check this response, if incorrect, then failed authentication, register flow path terminates.As
Fruit is correct, then authenticate successfully.
Step 506, authenticates successfully if S-CSCF checks, then S-CSCF will send Cx to from HSS
Pop (Cx-Pull) message.
Step 507, HSS preserve to should the S-CSCF name of user, and return Cx and pop response
(Cx-Pull Response) message is to S-CSCF.S-CSCF preserves corresponding user profile.
Step 508, S-CSCF sends " 200OK " message to I-CSCF, represents and accepts this registration.
Simultaneously corresponding by starting this UE for S-CSCF third party's log off procedure intervalometer.
Step 509, I-CSCF forwards to P-CSCF should " 200OK " message.
Step 510, P-CSCF sends " 200OK " message to UE.
Third party's log off procedure Timer Controlling that following steps 511 and step 512 are started by step 508,
Third party's log off procedure timer expiry then triggers step 511.
Step 511, S-CSCF sends registration request (REGISTER) message to application server AS.
Step 512, application server AS returns " 200OK " message to S-CSCF, represents and accepts this
Registration.After S-CSCF receives " 200OK " message, the third party of this UE of set nullifies flag bit, represents
Initiate the third party's log off procedure for this UE.
If before in log off procedure, third party's log off procedure intervalometer of UE not yet overflows, this UE is again
Again initiate registration request (REGISTER).S-CSCF will stop the 3rd of this UE in registration process
Side's log off procedure intervalometer, and the address of the AS of the most nearest twice this UE request registration.
If consistent, then in registration process, no longer send the third party logon procedure to AS.
As fruit part is consistent, then for the AS that new AS list is consistent with in old AS list, no longer send out
Play the third party logon procedure.For inconsistent AS, for AS, S-CSCF in new AS list
Also need to initiate the third party logon procedure；For the AS in old AS list, need to initiate third party and nullify
Process.
Correspondingly, seeing Fig. 4, in the embodiment of the present invention, the step of the logout flow path of IMS is as follows:
Step 1, UE sends a SIP(Session Initiation Protocol to the P-CSCF found,
Session initiation protocol) REGISTER request.This request can comprise user's mark that needs are registered
Know symbol.
Step 2, this REGISTER request is processed, and REGISTER is asked by P-CSCF
It is sent to the I-CSCF selected.
Step 3, I-CSCF then can contact HSS, sends Cx to HSS and inquires about (Cx-Query) message,
To inquire about the address of S-CSCF.
Step 4, HSS selects S-CSCF, and S-CSCF address by Cx inquiry response
(Cx-Query Response) message issues I-CSCF.
Step 5, after completing S-CSCF and selecting, I-CSCF is transmitted to REGISTER request to select
S-CSCF.
S-CSCF is when receiving registration (REGISTER) request, if third party's log off procedure of this UE
Intervalometer does not the most overflow, then stop third party's log off procedure intervalometer of this UE.
Step 6, S-CSCF can find that this UE is not authorized to, and can send Cx authentication to HSS
(Cx-Authentication) message, to obtain authorization data.
Step 7, authentication data are passed through Cx Authentication Response (Cx-Authentication by HSS
Response) message returns to S-CSCF.
Step 8, S-CSCF " 401 unauthorizeds (Unauthorized) " response carrys out challenging user.And will
Message passes to I-CSCF.
At S-CSCF in " 401 " message (step 408) that I-CSCF transmits, including authenticating five yuan
Group:
User's response value (User Response, RES)；
Authentication-tokens (Authentication token, AUTN)；
Random number (Random number (used for authentication), RAND)；
Encryption key (Cipher Key, CK)；
Integrity Key (Integrity key, IK).
Step 9, " 401 unauthorizeds (Unauthorized) " response is sent to P-CSCF by I-CSCF.
Step 10, " 401 unauthorizeds (Unauthorized) " response is sent to UE by P-CSCF.
Step 11, UE can calculate the relevant ginseng in this " 401 unauthorizeds (Unauthorized) " response
Number, i.e. RAND and AUTN, and send one to P-CSCF and new comprise RAND's and AUTN
REGISTER。
Step 12, P-CSCF can find I-CSCF again, and by new REGISTER message (i.e.
The REGISTER comprising RAND and AUTN) it is sent to I-CSCF.
Step 13, I-CSCF then can contact HSS, sends Cx inquiry (Cx-Query) to HSS and disappears
Breath, to inquire about the address of S-CSCF.
Step 14, HSS passes through Cx inquiry response (Cx-Query the S-CSCF address chosen
Response) message issues I-CSCF.
Step 15, I-CSCF is transmitted to new REGISTER request the S-CSCF selected.
S-CSCF can check this response, if incorrect, then failed authentication, register flow path terminates.As
Fruit is correct, then authenticate successfully.
Step 16, authenticates successfully if S-CSCF checks, then S-CSCF will send Cx to HSS and push on
(Cx-Put) message.
Step 17, HSS preserve to should the S-CSCF name of user, and return Cx and push on response (Cx-Put
Response) message is to S-CSCF.S-CSCF preserves corresponding user profile.
Step 18, S-CSCF sends " 200OK " message to I-CSCF, represents and accepts this registration.
Step 19, I-CSCF forwards to P-CSCF should " 200OK " message.
Step 20, P-CSCF sends " 200OK " message to UE.
After step 21 and step 22 are improved, become optional process.
S-CSCF checks third party's log off procedure flag bit of this UE, it may be judged whether carried out third party's note
Pin process, set represents and has carried out third party's log off procedure, otherwise represents and does not carry out third party's log off procedure.
I) nullify if not done by third party, the S-CSCF last the third party logon procedure to this UE
The AS list of AS list and the third party logon procedure of this UE current compare.At note for the first time
During Ce, the HSS SAA message by SAR/SAA process, can carry to S-CSCF and comprise one
Or multiple AS(application server) the AS list of name, S-CSCF initiates the to each AS afterwards
Tripartite's registration process.In second time registration later, the HSS SAA message by SAR/SAA process,
The AS list comprising one or more AS name carried to S-CSCF, may be with the last time
AS list is different.
If completely the same, then registration process terminates in the 20th step, it is no longer necessary to carry out step 21 and step
The third party logon procedure of rapid 22.
If not quite identical, for part AS that new AS list is consistent with in old AS list,
It is no longer initiated the third party logon procedure by S-CSCF.
For part AS that new AS list is inconsistent with in old AS list, S-CSCF is right by initiation
The third-party registration answered or log off procedure.For new AS list comprises but in old AS list not
The AS comprised, S-CSCF also need to initiate the third party logon procedure；For old AS list comprises but
The AS not comprised in new AS list, needs to initiate third party's log off procedure.
If ii) third party's log off procedure intervalometer has overflowed, third party's log off procedure has occurred and that.Then
Need to continue step 21 and step 22.
Step 21, S-CSCF sends registration request (REGISTER) message to application server AS.
Step 22, application server AS returns " 200OK " message to S-CSCF, represents and accepts this note
Volume.
