Abstract
The invention discloses a method of user multipoint registering in the next generation network. After a first terminal is registered during soft exchanging as a first IP address, if the soft exchange receives a second register information sent by a second terminal of the same number as a second IP address, and judges that at the aging time of the register of the last time, the following steps is performed: A. the soft exchange sending the disagreement information of enrollment to the second terminal and after the second terminal receives the said information and judges that the register is still needed, the soft exchange sending information of forcibly registering; B. the soft exchange responding to the second terminal to allow to register. The said method can make the user stably call and normally register when the user uses the other IP address during the aging time of the register of the last time.
Description
Technical field
The present invention relates to a kind of communications field, relate in particular to a kind of next generation network (Next GenerationNetwork, NGN) method of middle user's multi-point registration.
Background technology
Along with the high speed development of technique of internet with popularize, people to the demand of multimedia service more and more widely, (Unified Communication, UC), multimedia one number service CRBT IN services such as (MUPT) constantly emerges in large numbers unified communication platform.Because it is simple that media user has a carrier, the mobility height, can realize the characteristics of unified communication, the user usually is to use (many computers) registration use in many places of same number, so just might cause multimedia, the voice user uses different IP repeated registrations, because H.323, SIP (Session Initial Protocol, session initiation protocol), MGCP (Media Gateway ControlProtocol, MGCP), H.248 wait VOIP (Voice over Internet Protocol, the networking telephone) the agreement the inside does not have relevant explanation, so just calls out a series of problem of bringing to VOIP.The situation that has following two kinds of schemes to come the standard unique user to use many computers to register at present is so that the user under the NGN normally uses.
Scheme one: registering IP address is not judged in soft switch
Do not judge the IP address, receive any one registration message, the IP address of stored number in the soft switch refresh registration server, as shown in Figure 1.If when registration used jack per line 27526584, in the stage one, if other customer calls 27526584 are arranged, the calling in this time will directed EP (EndPotint, terminal) 1, IP1; In the stage two, if other customer calls 27526584 are arranged, the calling in this time will directed EP2, IP2; Because user's registration all has an ageing time among the NGN at present, it is the time interval that soft switch requirement terminal sends registration message next time, in ageing time, need to initiate repeated registration to soft switch again, like this, the IP address of the number 27526584 in the soft switch just constantly is refreshed, the calling that continues this time with regard to the time and point to EP1, the time and point to EP2, cause the instability of calling.
Scheme two: registering IP address is judged in soft switch
Check the IP address, the last registration of record Call-ID number, i.e. registration transactions number.As shown in Figure 2, if soft switch receive registration message 2 that EP2 sends be in the agreement registration message of receiving at EP1 1 that sends by soft switch with ageing time in, and registration message 2 is not from original IP address, it is the registration message that IP1 sends, then soft switch sends refusal response, not the IP address of stored number (as 27526584) in the refresh registration server to registration message 2; As shown in Figure 3, if soft switch receive registration message 2 that EP2 sends be in the agreement registration message of receiving at EP1 1 that sends by soft switch with ageing time after (normally EP1 off-line), at this moment soft switch receives the register requirement of EP2, and IP address information that will refreshing service device institute number storing 27526584 is IP2.
Scheme two increases a process of judging the IP address than scheme one as can be seen, but stable calls, but in real world applications, still have following defective: if client's use is two software terminal of same number, such as one in office, one of family, generally speaking, After Hours can be with the machine switched off of office, corresponding software terminal will withdraw from service, thereby that of family can normally use; In case but office machinery has forgotten to cut out (being that software terminal has been forgotten to withdraw from), wait come back home after, the software terminal in the computer is certain to not register, all relevant callings still can be routed on the machine of office.
Summary of the invention
It is a kind of in the ageing time of last once registration that technical problem to be solved by this invention is to provide, but the user use under the situation of another IP address registration stable calls still and also can the NGN of normal registration in the method for user's multi-point registration.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: the method that user's multi-point registration in a kind of next generation network is provided, first terminal is finished registration with an IP address in soft switch after, if soft switch receives second registration message that jack per line second terminal sends with the 2nd IP address, and soft switch judges it is in the ageing time of last once registration, then carries out following steps:
A, soft switch send to described second terminal and disagree with that registration message, second terminal receive this message and still need registration after judge it, then send to soft switch and force registration message;
B, soft switch are made response to second terminal, allow registration.
Described pressure registration message carries extended field, shows to force registration.
Also comprise step C between described steps A and the B: after soft switch receives the pressure registration message of second terminal transmission, send logout message to first terminal.
Also comprise step D after the described step C: first terminal directly sends to soft switch agrees logout message; Or first terminal notifying whether agree to nullify, if agree, then the execution in step B or first terminal send to soft switch and agree logout message, if disagree with, process ends then.
Also comprise step B1 after the described step B: the IP address of refreshing Subscriber Number is the 2nd IP address.
Described disagree with carry cause value in the registration message, showing has other-end registration.
Described logout message carries cause value, shows to use other IP address registrations.
In described steps A, judgement does not need registration if second terminal is received this message, and then second terminal is kept off-line state.
After first terminal was received described logout message, first terminal was initiated registration later on no longer automatically.
The invention has the beneficial effects as follows: because the method for user's multi-point registration has adopted the mode of forcing registration among the NGN of the present invention, therefore can make in the ageing time of last once registration, but the user uses under the situation of another IP address registration still stable calls and can normal registration, more freely use NGN equipment thereby be convenient to the user, enjoy the enjoyment that VOIP brings.

Embodiment
The method of user's multi-point registration among the NGN of the present invention, when first terminal is finished registration with an IP address in soft switch after, if soft switch receives second registration message that jack per line second terminal sends with the 2nd IP address, and soft switch judges it is in the ageing time of last once registration, then carries out following steps:
A, soft switch send to described second terminal disagrees with registration message, second terminal is received this message still needs registration after judge it, then send and force registration message to soft switch, judgement does not need registration if second terminal is received this message, then second terminal is kept off-line state, described disagree with carry cause value in the registration message, showing has other-end registration;
After B, soft switch receive the pressure registration message of second terminal transmission, send logout message and obtain its agreement to first terminal;
C, soft switch are made response to second terminal, allow registration;
D, the IP address of refreshing Subscriber Number are the 2nd IP address.
Described step B further may further comprise the steps:
After B1, soft switch receive the pressure registration message of second terminal transmission, send logout message to first terminal, described logout message carries cause value, shows to use other IP address registrations;
B2, first terminal send to soft switch agrees logout message.
After first terminal was received described logout message, first terminal was initiated registration later on no longer automatically, and made whether needing to initiate again the prompting of registering.
Do not initiate log-in command again or do not receive the button input if first terminal is received, then first terminal is kept off-line state; Again initiate log-in command if first terminal is received, and be in the ageing time of last once registration, then carry out following steps:
D1, soft switch are returned to first terminal and are disagreed with registration message;
After D2, first terminal were received and disagreed with registration message, whether prompting needed to force registration; If first terminal is received the pressure log-in command, then first terminal sends to soft switch and forces registration message;
After D3, soft switch receive the pressure registration message of first terminal transmission, send logout message to second terminal;
D4, second terminal send to soft switch agrees logout message;
D5, soft switch are made response to first terminal, allow registration.
See also Fig. 4, the soft switch of first embodiment of the invention receive registration message 2 that EP2 sends be in the agreement registration message of receiving at EP1 1 that sends by soft switch with ageing time in situation under NGN in the idiographic flow of user's multi-point registration as follows:
1) terminal 1 uses IP1 to send registration message 1 to soft switch;
2) soft switch is returned to terminal 1 and is agreed registration message 1, and carries ageing time;
3) to refresh the IP address of number 27526584 be IP1 in soft switch;
4) terminal 2 uses IP2 to send registration message 2 to soft switch in ageing time;
5) soft switch is returned to terminal 2 and is disagreed with and carry cause value by registration message: the other-end registration has been arranged; Disagree with that registration message belongs to the message that has the cause specific value, specific as follows, increased the cause specific value: another UE has been registered with this number;
This cause specific value of disagreeing with registration message is expressed as follows:
Reason：Q.850；cause＝21；text＝″another?UE?has?been?registered?with?thisnumber″
6) terminal 2 is received and is disagreed with registration message, then prompting: there has been terminal to use the duplicate numbers registration, need to force registration? (receive the NO order or do not receive the button input as if terminal 2, then keep off-line state);
7) if terminal 2 is received the YES order; Then
8) terminal 2 is initiated to force registration message 3 to soft switch, carries extended field: force registration; Force registration message 3 to belong to the registration message of expansion, specific as followsly (expanded the parameter of a register-type (registration type) in Expires (off period) header field the inside, when the value of this parameter is under the situation of force register, expression is to force registration, default situations is normal, and this parameter is not represented normal yet);
The extended field of this pressure registration message 3 is expressed as follows:
Expires：300；register-type＝″force?register″
9) soft switch sends logout message 4 to terminal 1, and cause value is: use other IP registrations; Logout message 4 increases reason header field, message following (Expires:0 represents logout message, and the cancellation mode is forcederegister, and carrying reason in addition is another UE registered with other IP);
The cause value of this logout message 4 is expressed as follows:
Reason：Q.850；cause＝21；text＝″another?UE?registered?with?other?IP″
10) terminal 1 directly send to be agreed logout message 4 to soft switch, or whether terminal 1 prompting agree to nullify, if agree that then execution in step 11) or terminal 1 send to soft switch and agree logout message 4, if disagree with, process ends then; Agree logout message 4 for nullifying response message, as long as the expire=0 among the Contact is just passable, corresponding to the expire=0 of logout message 4, not expansion;
11) soft switch is returned to terminal 2 and is agreed to allow registration by registration message 3;
12) to refresh the IP address of number 27526584 be IP2 in soft switch.
In above-mentioned steps, after receiving cause value when terminal 1 and be the logout message 4 of " using other IP registrations ", no longer automatically, initiate registration after the terminal 1, and make corresponding prompting, need to initiate again registration? YSE or NO are if terminal 1 is received the NO order or do not received the button input, then keep off-line state, if terminal 1 is received the YES order, then terminal 1 meeting employing is identical with the flow process of above-mentioned terminal 2, repeats no more herein.
Second embodiment of the invention is compared with the flow process of user's multi-point registration among the NGN of first embodiment, the flow process of distinguishing user's multi-point registration among the NGN that is second embodiment does not have step 9) and 10), be that terminal 2 is after soft switch is initiated to force registration message 3, terminal 1 is not notified in soft switch, directly allows terminal 2 registrations.
Third embodiment of the invention is compared with the flow process of user's multi-point registration among the NGN of first embodiment, difference is that the 3rd embodiment does not have step 10), be that terminal 2 is after soft switch is initiated to force registration message 3, soft switch sends logout message 4 to terminal 1, soft switch is without the agreement of terminal 1 then, directly return and agree to allow registration by registration message 3 to terminal 2.
The main application scenarios of the method for user's multi-point registration is to have a plurality of distinct devices, terminal to use the environment of same number among the NGN of the present invention, solves the registration problem of bringing thus, so that the user more freely uses NGN equipment, enjoys the enjoyment that VOIP brings.H.323 the VOIP agreement that the present invention relates to includes but not limited to, SIP, and MGCP, H.248
