Abstract
A method of using original dialog protocol SIP to accomplish the third part logout operation is characterized in that: the register server receives message of the third part logout operation, when terminal which initiates logout action is terminal which does not initiate register action, register server reserves the binding relationship of logout address and current account within remained effective time of subsistence period of logout address, and marks it for rejecting to update the logout address periodically; At the same time, terminal exceeds next periodic updating action based on successful response returned by register server, or does not initiate periodic updating action based on failed response returned by register server to guarantee the realization of logout action. The method is easy, work is reliable, and the false logout problem induced by the logout initiator and the register initiator are different can be resolved efficiently.
Description
Technical field
The present invention relates to SIP registrar server and the sip terminal a kind of implementation method in logout service, exactly, relate to a kind of method of using the initial session Session Initiation Protocol to finish third party's logout service; Belong to the applied technical field of Session Initiation Protocol in communication service.
Background technology
The initial session Session Initiation Protocol is one of the most active communication protocol of present industry.Now, all adopt Session Initiation Protocol as its core protocol as the flexible exchanging network and the multimedia domain, MMD among the 3G mobile network of one of PSTN network next generation network evolution direction, for the user provides solution.
The sign that Session Initiation Protocol will be discerned user identity is called user account, and the SIP network can distribute one or more numbers of the account for each user, and this number of the account can show as the E.164 number of SIP URI or extensive use at present in form.The user is then externally open with number of the account, as the total sign of other customer contacts oneself.Like this, the process of seeking the user in fact just becomes informs network with certain account information, requires network to find this number of the account user's process again.Because Session Initiation Protocol runs on the IP network usually, i.e. the general IP based network transmission of Session Initiation Protocol, and be the basic characteristics of IP network based on the IP addressing of address.Therefore the final result who seeks the user finds the IP address at the current place of user.
The registration behavior is the very important function of Session Initiation Protocol, and sip terminal is finished the binding relationship of number of the account and IP address by registration.Sip user can change the binding relationship of own current address (being the IP address) and number of the account very neatly at any time by registration; The user also can finish the binding and the change of own IP address and number of the account by other people under inconvenient situation.In Session Initiation Protocol, a number of the account can be bound one or more contact addresses.
The behavior relevant with registration comprises: address registration, register update, trade mark enquiries, cancellation.
Generally speaking, after sip terminal succeeded in registration, registrar can be set a timeliness scope, only showed that the binding relationship of current address and number of the account is just effective in this time period.Usually, only have an address information in the registration message, show the current binding relationship of account information and this address; But also might in a log-on message, have a plurality of addresses, show this number of the account simultaneously with the binding relationship of a plurality of contact addresses, perhaps a plurality of numbers of the account and a plurality of contact addresses distinguish corresponding binding relationship separately.Latter event wherein shows that usually a terminal acts on behalf of the registration and the corelation behaviour of other addresses as agent equipment.
For guaranteeing the validity of address; sip terminal usually can be before end life cycle of current address; initiate another one registration message (this message belongs to same registration message with original registration message, just increases message SN), the behavior is called registration period renewal or register update.
After succeeding in registration in the address, the user also can initiatively initiate logout message, requires registrar to remove the binding relationship of number of the account and current certain or a plurality of addresses, is referred to as cancellation.The cancellation behavior is normally finished by the terminal of initiating registration.On Business Processing process or demand, the situation that also may exist the cancellation behavior to be initiated by the non-terminal of finishing registration is called " third party " and nullifies this moment.
By under the prerequisite of authentication, when registrar was received de-registration request at certain address, registrar will be removed the current binding relationship of this address and number of the account.When the terminal oneself of initiating registration was carried out the cancellation operation, in general, this terminal can not initiated initiatively more new behavior in follow-up time.But, when " third party " cancellation takes place, will there be following problem:
At the cancellation of certain address B by non-be this B address registration " third party " terminal when initiating, by under the prerequisite of authentication, registrar will be removed the binding relationship of this B address and a certain number of the account.Stipulate according to RFC3261, registrar can not send the bulletin that this address has been canceled to the current terminal of still " knowing nothing ", finish the initiation registration of B address and number of the account binding relationship, so that after this terminal receives bulletin, no longer initiate cycle new behavior more.
Like this, because there is cycle new behavior more in Session Initiation Protocol, the terminal of before having finished the B address registration still can be initiated cycle new behavior more.After registrar was received this cycle updating message, registrar can be thought new register requirement, thereby accepts this registration, and bound the corresponding relation of number of the account and B address in himself database again, caused " the false cancellation " thus.
The professional defective that " the false cancellation " behavior directly causes is: according to user's cancellation behavior, the B address is rejected from current binding data tabulation, when calling out this user's request, soft switch or switch should be to the B addressing of address.Yet because the existence of " the false cancellation " problem, soft switch or exchange opportunity continue to carry out route to B address (being current contact address of not wishing addressing), cause professional defective or fault.
Summary of the invention
In view of this, the purpose of this invention is to provide a kind of method of using initial session protocol SIP to finish third party's logout service, initiate cancellation behavior side and initiate registration behavior side both inconsistent and professional defective or faults that vacation that cause is nullified problem and caused so that can solve preferably.
In order to achieve the above object, the invention provides a kind of method of using initial session protocol SIP to finish third party's logout service, it is characterized in that: registrar is received the message of third party's logout service, when the terminal of finding initiation cancellation behavior is the terminal of non-initiation registration, registrar should remain in effective time in this life cycle that is canceled the address and continue to keep this and be canceled the binding relationship of address and current number of the account, and carry out special identifier so that will at the cycle that is canceled the address more new behavior refuse; Simultaneously, next time cycle more new behavior, the perhaps failure response that returns according to registrar are proceeded in the success response that terminal will be returned according to registrar, no longer initiate at new behavior more of original cycle that is canceled the address, to guarantee the real realization of cancellation behavior.
Be that registrar is the effective time that certain number of the account of each address binding sets described life cycle, is generally 30～60 minutes.
Described registrar will be at the cycle that is canceled the address when more new behavior is refused, and two kinds of situations are arranged:
(1) current when being canceled the address when only having in the cycle updating message of initiating, registrar will send failure response to current register requirement, requires this terminal not initiate cycle new behavior more again;
(2) in the cycle updating message of initiating except the binding data that comprises current address that is canceled and number of the account, when also comprising other binding datas, registrar no longer has the current address that has been canceled in the success response of replying, require this terminal no longer to have this current address that is canceled in the cycle update request of initiating next time.
Current when being canceled the address when only having in the cycle updating message of initiating, the signaling process of described method comprises following operating procedure:
(1) first terminal (A1) is initiated login request message to registrar, so that first IP address at this terminal (A1) place and user's number of the account (A) are bound, comprises the binding relationship of first IP address and number of the account (A) in this request message;
(2) registrar carries out authentication to register requirement, if by authentication, registrar returns success response to first terminal (A1), and expression is succeeded in registration; The effective time that has binding data [number of the account (A), first IP address] in this success response; If, do not finish this flow process by authentication;
(3) registrar receives the de-registration request message of second terminal (A2), promptly requires the binding relationship of unbind data [number of the account (A), first IP address]: in this message, the timeliness of binding data [number of the account (A), first IP address] is 0;
(4) registrar carries out authentication to the cancellation behavior, if pass through authentication, registrar is approved this number of the account (A) and first IP address unbind relation, registrar returns success response to second terminal (A2), simultaneously, registrar will be to binding data [number of the account (A), first IP address] add and to show the special identifier that this binding relationship has been disengaged, and continue to safeguard this binding data residue effective time of life cycle, so that wait for the cycle update request of first terminal (A1); If, do not finish this flow process by authentication;
(5) registrar will be deleted binding data [number of the account (A) under following three kinds of situations, first IP address]: still be in effective time in current life cycle, registrar is received at binding data [number of the account (A), first IP address] the cycle updating message or new initial registration message, perhaps when the effective time of current life cycle vanishing;
(6) first terminal (A1) in life cycle after succeeding in registration, is initiated cycle registration updating message to registrar thereon;
(7) after registrar receives the cycle registration updating request message of first terminal (A1) to binding data [number of the account (A), first IP address], return failure response to this first terminal (A1);
(8) after first terminal (A1) is received failure response, no longer initiate at cycle of user A new behavior more.
When in the cycle updating message of initiating except comprising the current binding data that is canceled address and number of the account, when also comprising other binding datas, the signaling process of described method comprises following operating procedure:
(1) because first terminal (A1) and other-end can not send registration message to registrar, so the agency sends register requirement to registrar by second terminal (A2), except the binding data that comprises first IP address and number of the account (A), also include the binding data of number of the account (A) or other numbers of the account and first IP address or other IP addresses in the register requirement that second terminal (A2) sends;
(2) registrar carries out authentication to register requirement, if by authentication, registrar returns success response to second terminal (A2), and expression is succeeded in registration; The effective time that has described each number of the account and IP address binding data in this success response simultaneously; If, do not finish this flow process by authentication;
(3) registrar is received the de-registration request message that non-second terminal (A2) initiated, and promptly require the binding relationship of unbind data [number of the account (A), first IP address]: in this message, the timeliness of binding data [number of the account (A), first IP address] is 0;
(4) registrar carries out authentication to the cancellation behavior, if pass through authentication, registrar approval binding data [number of the account (A), first IP address] the unbind relation, registrar returns success response to the terminal of initiating the cancellation behavior, simultaneously, registrar will be to binding data [number of the account (A), first IP address] add and to show the special identifier that this binding relationship has been disengaged, and continue to safeguard this binding data residue effective time of life cycle, so that wait for the cycle update request of second terminal (A2); If, do not finish this flow process by authentication;
(5) registrar will be deleted binding data [number of the account (A) under following three kinds of situations, first IP address]: still be in effective time in current life cycle, registrar is received at binding data [number of the account (A), first IP address] the cycle updating message or new initial registration message, perhaps when the effective time of current life cycle vanishing;
(6) second terminals (A2) in life cycle after succeeding in registration, are initiated cycle registration updating request message to registrar thereon, still have binding data [number of the account (A), first IP address] in this message;
(7) after registrar receives the cycle registration updating request of second terminal (A2) transmission, find wherein binding data [number of the account A, first IP address] currently be canceled, registrar then no longer has binding data [number of the account (A) in the success response that second terminal (A2) returned, first IP address], and the binding data of other numbers of the account that are not canceled and IP address is only arranged, promptly require second terminal (A2) to initiate only to carry the binding data that remains valid in the next cycle updating message;
After (8) second terminals (A2) are received success response, only having the current effective binding data in the cycle updating message next time.
The present invention is a kind of method of using Session Initiation Protocol to finish third party's logout service, simple, the easy row of operating procedure, reliable operation, this method can efficiently and effectively solves to be initiated cancellation behavior side both is inconsistent and the appearance of phenomenon is nullified in vacation that cause with initiating registration behavior side, with and the variety of issue that brought, the smooth realization of strong guarantee logout service.Adopt the inventive method, under the prerequisite that authentication is passed through, the user can be anywhere, any time, adopts any terminal to finish change to the contact address; Reduced registration greatly, nullified the coupled relation of behavior, the terminal of promptly initiating to nullify can adopt and register identical or different terminal.
As the application under a kind of expansion or the special screne, the present invention has special advantage for following system: if system only supports the application of an IP address of a number of the account binding, when receiving the registration message of " same number of the account; another IP address " binding data of another one terminal when registrar, system will think that a back register requirement is cancellation or the replacement to previous register requirement, thereby the binding relationship of this number of the account will be re-set as the binding data of a back register requirement.Like this, these two terminals all can be initiated cycle new behavior more, make the binding data that relates to this number of the account in the registrar to change continually, cause in the different time sections, and network is to the addressing difference of number of the account.Yet this network is that the user does not wish to occur to the phenomenon of the addressing frequent variations of number of the account.Adopt the inventive method, can effectively solve the defective of said system, guarantee professional normal enforcement.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
In order to prevent false cancellation situation, developed method of the present invention: registrar is received the message of third party's logout service, when the terminal of i.e. discovery initiation cancellation behavior is the terminal of non-initiation registration, registrar should continue to keep this in this residue life cycle (being generally 30～60 minutes) that is canceled the address and be canceled the binding relationship of address and current number of the account in effective time, and carry out special identifier so that will at the cycle that is canceled the address more new behavior refuse; Simultaneously, next time cycle more new behavior, the perhaps failure response that returns according to registrar are proceeded in the success response that terminal will be returned according to registrar, no longer initiate at original registration period that is canceled address new behavior more, to guarantee the real realization of cancellation behavior.
Referring to Fig. 1, introduce cycle that registrar among the present invention initiates the terminal that is canceled the address two kinds of situations refusing of new behavior more:
When only having the current binding data that is canceled in the cycle updating message of initiating, registrar will send the refusal response to current register requirement, requires this terminal not initiate cycle new behavior (shown in Fig. 1 (A)) more again;
In the cycle updating message of initiating except comprising the current binding data that is canceled, when also having other binding datas, registrar no longer comprises the current address that has been canceled in the success response of replying, require this terminal no longer to have this current address that is canceled (shown in Fig. 1 (B)) in the cycle update request of initiating next time.
Following mask body is introduced the third party's cancellation of above-mentioned two kinds of different scenes and the sequential chart of signaling process thereof.
Referring to Fig. 2, user A has two address 1, addresses 2 of initiating register requirement separately respectively, promptly in the address 1, address 2 is provided with terminal A1 and terminal A2 respectively.After succeeding in registration, initiate to nullify the operation of address 1 by the terminal A2 that is positioned at address 2.Include only the current address that has been canceled (its signaling process as shown in Figure 3) in the cycle updating message of this moment.
Referring to Fig. 3, introduce the signaling process sequential chart (omitted authentication process in the diagram flow process, had authentication process in the practical operation) in Fig. 2 application scenarios:
(1) terminal A1 sends register requirement REGISTER message to the registration (address 1 and address 2 all are bundled under the user A number of the account, and terminal A2 succeeds in registration to registrar before this) of registrar initiation at address 1.The binding relationship that comprises address 1 and user A number of the account in this message.
(2) (authentication is by the back), registrar will send success response 200 message to terminal A1, and expression is succeeded in registration.Be 30 minutes effective time (being life cycle) that has address 1 in this response message simultaneously.After terminal A1 succeeds in registration,, have two registration contact IP addresses simultaneously: the address 2 at the address 1 at terminal A1 place and terminal A2 place at the number of the account of user A.
(3) the terminal A2 of address 2 initiates the de-registration request REGISTER to address 1, promptly sends de-registration request message to registrar, and be 0 the effective time that shows address 1 in this message.
(4) (authentication is by the back), registrar authorised user A will concern that registrar sends success response 200 message to the terminal A2 that is positioned at address 2 with address 1 unbind.Registrar adds binding data [number of the account A, address 1] and shows the special identifier that this binding relationship has been disengaged, and continues to safeguard the residue effective time of the life cycle of this binding data, so that the latent period update request.
(5) for being positioned at the terminal A1 of address 1, can in the life cycle (30 minutes) after last one is succeeded in registration, initiate cycle registration updating message REGISTER to registrar.
(6) receive the cycle registration updating of address 1 after, registrar sends failure response 403 message Forbidden to the terminal A1 that is positioned at address 1.
(7) after the terminal A1 that is positioned at 1 place, address receives failure response 403 message, no longer initiate at cycle of account A new behavior more.
Referring to Fig. 4, user A binding has two addresses 1, address 2, and this address 1, address 2 be counterpart terminal A1 and terminal A2 respectively.Before this, for a certain reason, terminal A1 can not send registration message to registrar, but is 2 registrations of address 1 and address simultaneously by terminal A2.After succeeding in registration, the terminal (being nonterminal A2) that is positioned at address 6 initiates to nullify the operation of address 1.Just exist two binding datas (its signaling process as shown in Figure 5) in the subsequent cycle updating message this moment.
Referring to Fig. 5, introduce the signaling process sequential chart (omitted authentication process in the diagram flow process, had authentication process in the practical operation) in Fig. 4 application scenarios:
(1) terminal A2 initiates register requirement REGISTER message (being about to address 1 and address 2 all is bundled under the number of the account of user A) at address 1 and address 2 to registrar, comprise in this request message address 1 and address 2 simultaneously with the binding data of number of the account A.
(2) (authentication is by the back), registrar sends success response 200 message to terminal A2, and expression is succeeded in registration.Be 30 minutes effective time (being life cycle) that has address 1 and address 2 in this response message simultaneously.At this moment, the number of the account of user A is bound two IP addresses simultaneously: the address 2 at the address 1 at terminal A1 place and terminal A2 place.
(3) terminal of address 6 is initiated the de-registration request to address 1, and promptly the terminal of address 6 sends de-registration request REGISTER message to registrar, and be 0 the effective time that shows address 1 in this message.
(4) (authentication is by the back), registrar authorised user A will concern that registrar sends success response 200 message to the terminal A2 that is positioned at address 2 with address 1 unbind.Registrar adds binding data [number of the account A, address 1] and shows the special identifier that this binding relationship has been disengaged, and continues to safeguard the residue effective time of the life cycle of this binding data, so that the latent period update request.
(5), will in the life cycle (30 minutes) after last one is succeeded in registration, initiate cycle registration updating REGISTER message to registrar for terminal A2.
(6) receive the cycle registration updating message that terminal A2 sends after, registrar finds that address 1 is current and is canceled, registrar only has the binding data of address 2 and account A then in success response 200 message that terminal A2 sends; The information that should have only address 2 during the next cycle that promptly requires terminal A2 to initiate upgrades.
(7) receive success response 200 message that registrar sends after, the terminal A2 that is arranged in address 2 will only have the information of address 2 in the cycle next time of its initiation updating message, promptly no longer initiates at cycle of address 1 new behavior more.
The present invention has taked said method to carry out test enforcement, and the result of test is successful, can be applicable in existing every business, has realized goal of the invention.
