In order to clearly show the scheme and beneficial effect of the embodiment of the present invention, illustrate the embodiment of the present invention in specific expansion
Before, the process of the process first to the function of SCP AS, caller VPMN business and called VPMN business is illustrated respectively.
The function that SCP AS is realized when handling calling service mainly has: judging whether calling subscriber and called subscriber are in
The same VPMN group, judges whether calling subscriber has call authority, and ticket of the record calling subscriber on SCP AS.
The function that SCP AS is realized when handling called service mainly has: the caller identification of called subscriber handled,
It determines the type of called subscriber's caller identification number, such as can be used with the true number or display of calling of display of calling user
Short codes of the family under VPMN group；Ticket of the called subscriber on SCP AS is recorded, wherein the specific charging rule of called subscriber
Then determined by each operator policies.
Further, in order to make it easy to understand, coming respectively below with reference to a specific example to the stream of caller VPMN business
The process of journey and called VPMN business is illustrated.
The business AS of calling subscriber's signing is respectively to service centralization and application server for continuity (Service
Centralization And Continuous, SCC AS), telephone service application server (Telephone AS, TEL
AS), SCP AS and other AS, and the priority triggered is followed successively by SCC AS, TEL AS, SCP AS and other AS.That is,
For originating S-CSCF when handling the service request of calling subscriber, the AS for needing successively to trigger is respectively SCC AS, TEL AS, SCP
AS and other AS.
The business AS of called subscriber's signing is respectively SCC AS, TEL AS, SCP AS and other AS, but the priority triggered
It is followed successively by other AS, SCP AS, TEL AS and SCC AS.
Wherein, other AS refer to remaining AS removed except SCC AS, TEL AS and SCP AS.In this example, main
All only have an other AS in the business AS for making user and called subscriber contract.Certainly, in other specific embodiments, user
There can also be a number of other AS in the business AS of signing, or without other AS.
Fig. 1 shows the flow chart for opening user's calling service in VoLTE network of VPMN business.Below with reference to Fig. 1
The process that originating S-CSCF in the example triggers each AS under VoLTE network is described in detail, i.e. originating S-CSCF disappears request
Breath is sent to the detailed process of called I-CSCF.
S110, originating S-CSCF receive caller proxy call session control function (Proxy-Call Session
Control Function, P-CSCF) after the request message (INVITE) that sends, originating S-CSCF is according to sending request message
The IFC of user's signing, confirmation triggering rule.In other words, the IFC that originating S-CSCF is contracted according to calling subscriber, confirmation will touch
The sequencing of the AS and each AS of triggering of hair.
The caller P-CSCF received the request message sent is transmitted to by S120, originating S-CSCF according to triggering rule
Caller SCC AS.
After S120-1, caller SCC AS receive the request message of originating S-CSCF transmission, specific service logic is executed,
Request message is sent after the completion to originating S-CSCF.
S130 after originating S-CSCF receives the request message of caller SCC AS transmission, is executed next according to triggering rule
The caller SCC AS received the request message sent is transmitted to caller TEL AS by the triggering of a AS.
After S130-1, caller TEL AS receive the request message of originating S-CSCF transmission, specific service logic is executed,
Request message is sent after the completion to originating S-CSCF.
S140 after originating S-CSCF receives the request message of caller TEL AS transmission, is executed next according to triggering rule
The caller TEL AS received the request message sent is transmitted to caller SCP AS by the triggering of a AS.
After S140-1, caller SCP AS receive the request message of originating S-CSCF transmission, specific service logic is executed,
Request message is sent after the completion to originating S-CSCF.
S150 after originating S-CSCF receives the request message of caller SCP AS transmission, is executed next according to triggering rule
The caller SCP AS received the request message sent is transmitted to the other AS of caller by the triggering of a AS.
After S150-1, the other AS of caller receive the request message of originating S-CSCF transmission, specific service logic is executed,
Request message is sent after the completion to originating S-CSCF.
S160, after originating S-CSCF receives the request message that the other AS of caller are sent, confirmation is completed to all AS's
The other AS of the caller received the request message sent is transmitted to called I-CSCF by triggering, i.e. request message is sent to called
Side processing.
After being sent to callee side below with reference to Fig. 2 detailed description request message, terminating S-CSCF is in VoLTE net in the example
The process of each AS is triggered under network.Fig. 2 shows the processes for the user's called service in VoLTE network for opening VPMN business
Figure.
The request message that the originating S-CSCF received is sent is sent to called subscriber's registration by S210, called I-CSCF
Terminating S-CSCF.
S220, after terminating S-CSCF receives the request message that called I-CSCF is sent, according to called subscriber's signing
IFC, confirmation triggering rule.
The called I-CSCF received the request message sent is transmitted to by S230, terminating S-CSCF according to triggering rule
It is called other AS.
S230-1 executes specific service logic after being called the request message that other AS receive terminating S-CSCF transmission,
Request message is sent after the completion to terminating S-CSCF.
S240, terminating S-CSCF receives be called the request message that other AS are sent after, executed according to triggering rule next
The other AS received the request message sent is transmitted to called SCP AS by the triggering of a AS.
S240-1 executes specific service logic after called SCP AS receives the request message of terminating S-CSCF transmission,
Request message is sent after the completion to terminating S-CSCF.
S250 after terminating S-CSCF receives the request message that called SCP AS is sent, is executed next according to triggering rule
The called SCP AS received the request message sent is transmitted to called TEL AS by the triggering of a AS.
S250-1 executes specific service logic after called TEL AS receives the request message of terminating S-CSCF transmission,
Request message is sent after the completion to terminating S-CSCF.
S260 after terminating S-CSCF receives the request message that called TEL AS is sent, is executed next according to triggering rule
The called TEL AS received the request message sent is transmitted to SCC AS by the triggering of a AS.
S260-1 executes specific service logic after called SCC AS receives the request message of terminating S-CSCF transmission,
Request message is sent after the completion to terminating S-CSCF.
S270, after terminating S-CSCF receives the request message that called SCC AS is sent, confirmation is completed to all AS's
The called SCC AS received the request message sent is transmitted to the P-CSCF of called subscriber's registration, and then called P- by triggering
Request message is sent to called subscriber by CSCF.
By above-mentioned example it is found that the user for opening VPMN business triggers SCP AS in calling service and called service.
But for VPMN business, when only calling subscriber and called subscriber are in same VPMN group, just it is necessary to trigger quilt
It is SCP AS, other situations do not need to trigger called SCP AS, and concrete condition is as shown in table 1.Table 1 is call business and is called
The corresponding relationship of side triggering SCP AS.
Table 1
Also, when showing that callee side triggers SCP AS business by test, call proceeding time delay will averagely increase by 200 milliseconds
(ms).Therefore, the increase of call proceeding time delay will be will lead to by carrying out unnecessary triggering to called SCP AS.
In view of this, the embodiment of the invention provides a kind of method for triggering virtual private mobile network service, callee side S-
It with the presence or absence of caller and is called in the message related to calls that CSCF is sent by identification Calling Side as the mark of same VPMN group, comes really
It is fixed whether to trigger called SCP AS, to reduce the unnecessary triggering to called SCP AS.
Fig. 3 shows the flow chart that the method for virtual private mobile network service is triggered in the embodiment of the present invention.Reference Fig. 3,
It mainly includes S310 to S350 that the method for virtual private mobile network service is triggered in the embodiment of the present invention.
S310, originating S-CSCF receive the first request message, according to the IFC of calling subscriber, trigger non-SCP AS and master
It is SCP AS.
In some embodiments, the first request message (for example, INVITE) that user terminal is sent can pass through caller P-
CSCF is sent to originating S-CSCF.That is, the first request message that the user terminal that originating S-CSCF receives is sent can
Being forwarded by caller P-CSCF.
In addition, it should be noted that non-SCP AS refers to remaining removed except SCP AS in the AS of user's signing
AS.
S320, originating S-CSCF receives the second request message that caller SCP AS is sent, if calling subscriber and called subscriber
In same VPMN group, the second request message includes the mark of calling subscriber and called subscriber in same VPMN group.
In some embodiments, when originating S-CSCF is triggered to SCP AS, caller SCP AS judge calling subscriber and by
Cry whether user is in same VPMN group.
If the number of the called subscriber of calling subscriber calls is the true number of called subscriber, caller SCP AS can lead to
It crosses and searches group's information belonging to group's information belonging to rear subscriber number and called number in the internal database of itself,
To judge whether calling subscriber and called subscriber are in same VPMN group.
If group's information belonging to rear subscriber number is identical with group's information belonging to called number, caller SCP AS
Determine that calling subscriber and called subscriber are in same VPMN group.If group's information and called number belonging to rear subscriber number
Affiliated group's information is not identical, then caller SCP AS determines that calling subscriber and called subscriber are not in same VPMN group.
If the number of the called subscriber of calling subscriber calls is the short codes that called subscriber uses under certain VPMN group,
Caller SCP AS can be by searching group's information belonging to rear subscriber number, to judge to lead in the internal database of itself
Cry whether user and called subscriber are in same VPMN group.
If there are the short codes of calling subscriber calls under group belonging to rear subscriber number, caller SCP AS determines master
User and called subscriber is made to be in same VPMN group.If calling subscriber calls are not present under group belonging to rear subscriber number
Short codes, then caller SCP AS determines that calling subscriber and called subscriber are not in same VPMN group.
Further, it if caller SCP AS determines that calling subscriber and called subscriber are in same VPMN group, leads
Make SCP AS that can set calling subscriber and called subscriber in the call request message for being sent to originating S-CSCF same
The mark of VPMN group.
Specifically: it can first increase an extension header field in the call request message for being sent to originating S-CSCF, such as
P-Group-Information.Then, calling subscriber and called subscriber are set in increase in the mark of same VPMN group
Extension header field P-Group-Information in.Using this setting means, each AS support pair inside operator is needed
Putting for extension header field is logical.
It can also be set in directly by calling subscriber and called subscriber in the mark of same VPMN group and be sent to caller S-
In the Call-Info of the call request message of CSCF.Using this setting means, it is also desirable to confirm each AS to Call-
Info header field it is supportive.
It can also be set in by calling subscriber and called subscriber in the mark of same VPMN group and be sent to originating S-CSCF
Call request message message body XML information in.Using this setting means, need calling subscriber and called subscriber same
The mark of one VPMN group meets XML format.
In addition, if AS is not present between caller SCP AS and called SCP AS, i.e. the last one triggering of Calling Side SCP AS,
First triggering SCP AS of callee side.In this case, can by calling subscriber and called subscriber same VPMN group mark
Know, is set in the Tag parameter for being sent to the From header field of the call request message of originating S-CSCF.For example, Tag can be joined
Number is arranged to the character string that identification strings merge with random string, and wherein identification strings characterize calling subscriber and are called
Mark of the user in same VPMN group.
If calling subscriber and called subscriber are not in same VPMN group, caller SCP AS is being sent to caller S-
Calling subscriber and called subscriber are not set in the call request message of CSCF in the mark of same VPMN group.
Therefore, if calling subscriber and called subscriber are in same VPMN group, then the second request that caller SCP AS is generated
Message includes the mark of calling subscriber and called subscriber in same VPMN group.If calling subscriber and called subscriber be not same
VPMN group, then the second request message that caller SCP AS is generated does not include calling subscriber and called subscriber in same VPMN collection
The mark of group.
Third request message is sent to called I-CSCF by S330, originating S-CSCF, and third request message is based on second
The request message that request message generates, if calling subscriber and called subscriber are in same VPMN group, third request message includes mark
Know.
In some embodiments, if Calling Side the last one triggering SCP AS, then originating S-CSCF receives caller SCP
After the second request message that AS is sent, the second request message is just sent to called I-CSCF.That is, if the last one touching of Calling Side
SCP AS is sent out, then third request message is identical as the second request message.In other words, the specific format of third request message with
The specific format of second request message is identical.For example, if calling subscriber and called subscriber are in the mark of same VPMN group
In the Call-Info of second request message, then calling subscriber and called subscriber also locate in the mark of same VPMN group
In the Call-Info of third request message.
If AS of the last one triggering of Calling Side is not SCP AS, then originating S-CSCF receives the of SCP AS transmission
After two request messages, it will continue to other AS of triggering calling subscriber's signing, until originating S-CSCF confirmation is completed to all AS
Triggering.Also, originating S-CSCF is after the third request message that the AS for receiving last triggering is sent, by third request message
It is sent to called I-CSCF.
Obviously, third request message is that other AS are generated based on the second request message.Wherein, if calling subscriber and called
User is in same VPMN group, then third request message equally also includes calling subscriber and called subscriber in same VPMN group
Mark.Also, the position that this mark is in third request message can be with this mark in the second request message
The position being in is identical.For example, if calling subscriber and called subscriber are in the second request message in the mark of same VPMN group
Extension header field in, then calling subscriber and called subscriber are also at the expansion of third request message in the mark of same VPMN group
It opens up in header field.Therefore, if the last one triggering of Calling Side is not SCP AS, then third request message is based on by other AS
The request message that second request message generates.
Third request message is sent to terminating S-CSCF by S340, called I-CSCF.
S350, terminating S-CSCF receive third request message, however, it is determined that third request message does not include mark, according to quilt
The IFC of user is made to trigger non-SCP AS.
In some embodiments, after terminating S-CSCF receives the third request message that called I-CSCF is sent, it is called S-
Whether CSCF judges in third request message to include the mark of calling subscriber and called subscriber in same VPMN group.
If in third request message not including the mark of calling subscriber and called subscriber in same VPMN group, then called
S-CSCF triggers non-SCP AS according to the IFC that called subscriber contracts, and does not trigger called SCP AS.
If in third request message including the mark of calling subscriber and called subscriber in same VPMN group, then called S-
CSCF triggers non-SCP AS and called SCP AS according to the IFC that called subscriber contracts, and receives not wrapping for called SCP AS transmission
Include the call request message of mark.
In some embodiments, after terminating S-CSCF triggers called SCP AS, called SCP AS can be sent to it is called
Calling subscriber and called subscriber are removed in the call request message of S-CSCF in the mark of same VPMN group.That is, by
It does not include calling subscriber and called subscriber same in the call request message that the called SCP AS for making S-CSCF receive is sent
The mark of VPMN group.Based on this, as the terminating S-CSCF AS of triggering following again, terminating S-CSCF that subsequent AS is received
In the call request message of forwarding, calling subscriber and called subscriber will not be carried in the mark of same VPMN group.
The method of triggering virtual private mobile network service provided in an embodiment of the present invention, caller SCP AS is by judging caller
Whether user and called subscriber are in same VPMN group, to determine whether the setting identification in the call request message of sending.
Also, if calling subscriber and called subscriber are in same VPMN group, and caller SCP AS is set in the call request message of sending
Calibration is known.On this basis, with the presence or absence of mark in the call request message that terminating S-CSCF is sent by identification Calling Side, come
Determine whether to trigger called SCP AS.If also, there is no mark, terminating S-CSCF in the call request message of Calling Side transmission
Called SCP AS is not triggered.Therefore, the method for triggering virtual private mobile network service provided in an embodiment of the present invention, can be avoided
Unnecessary triggering to called SCP AS, and then call proceeding time delay can be shortened.
Further, for the ease of the understanding to the embodiment of the present invention, come below with reference to a specific example to this hair
The process of the process of caller VPMN business and called VPMN business is illustrated respectively in bright embodiment.
The business AS of calling subscriber's signing is respectively SCC AS, TEL AS and SCP AS, and the priority triggered is followed successively by
SCC AS,TEL AS,SCP AS.The business AS of called subscriber's signing is respectively SCC AS, TEL AS and SCP AS, but trigger
Priority is followed successively by SCP AS, TEL AS and SCC AS.
Calling subscriber and called subscriber use calling subscriber and called subscriber in same VPMN group in same VPMN
Set-up mode of the flag of group in Tag parameter.
Fig. 4 shows the process that user's calling service in VoLTE network of VPMN business is opened in the embodiment of the present invention
Figure.The process of each AS is triggered under VoLTE network below with reference to originating S-CSCF in Fig. 4 the present invention will be described in detail embodiment.
S410, after originating S-CSCF receives the request message of P-CSCF transmission, originating S-CSCF disappears according to request is sent
The IFC of user's signing of breath, confirmation triggering rule.
S420, originating S-CSCF are transmitted to caller according to triggering rule, by the P-CSCF received the request message sent
SCC AS。
After S420-1, caller SCC AS receive the request message of originating S-CSCF transmission, specific service logic is executed,
Request message is sent after the completion to originating S-CSCF.
S430 after originating S-CSCF receives the request message of caller SCC AS transmission, is executed next according to triggering rule
The caller SCC AS received the request message sent is transmitted to caller TEL AS by the triggering of a AS.
After S430-1, caller TEL AS receive the request message of originating S-CSCF transmission, specific service logic is executed,
Request message is sent after the completion to originating S-CSCF.
S440 after originating S-CSCF receives the request message of caller TEL AS transmission, is executed next according to triggering rule
The caller TEL AS received the request message sent is transmitted to caller SCP AS by the triggering of a AS.
After S440-1, caller SCP AS receive the request message of originating S-CSCF transmission, specific service logic is executed,
And judge calling subscriber and called subscriber whether in same VPMN group.
Calling subscriber and called subscriber are being judged after same VPMN group, and caller SCP AS is set in request message
The mark of calling subscriber and called subscriber in same VPMN group.
