Abstract
The invention discloses a kind of applied to the call connection method of VPMN, system and device, the call proceeding flow passed through in the VPMN to prior art is simplified, and greatly reduces call delay.What deserves to be explained is although this process simplify call proceeding flow of the prior art, but use the call proceeding flow after simplifying to remain able to ensure the technique effect for successfully realizing call proceeding on the premise of charging is carried out to calling.
Description
Technical field
The present invention relates to communication technical field, more particularly to a kind of call proceeding side applied to VPMN
Method, system and device.
Background technology
VPMN（Virtual Private Mobile Network, VPMN）, it is commonly called as " group network ", " office
Domain net ", " corporate network " or " microgrid " etc., it is to establish a logical session private network on the net in public mobile communication.VPMN
Be customized for group customer, represent the business of group's the benefit of client, and provided for group customer a kind of high efficiency,
The INCOM intercom local area network services of low cost.Just look like to use when group customer carries out intercommunication using mobile phone
One's own mobile communication private network is equally convenient.
Specifically, VPMN can provide voice and video call to group customer internal members, and can realize it is internal into
The preferential group's business of rate such as the extension number dialing between member.When calling subscribe and called subscriber belong to a group（Exhale
Cry as on-net call）When, set according to the display mode of called subscriber, the caller identification content of called subscriber can be that caller is used
The short codes at family or the true number of calling subscribe.Summary is got up, function main VPMN have caller cornet calling,
Called cornet show and net in call meters it is preferential etc..
A typical call-connection process is as shown in Figure 1 in VPMN.Assuming that user A and user B are to belong to same group together
VPMN user, user A utilizes the long code or short codes calling party B that itself use, then corresponding call-connection process can
With including following step as shown in Figure 1：
Step 101, exchange system a receives user A calling, determines that user is according to user A signing information O-CSI
VPMN user, so as to send initial message IDP to cornet platform by signaling system；
Wherein, the true number of caller of the calling and called short codes/long code are carried in the IDP, it is described here
Long code is true number.
Step 102, cornet platform sends RRBE after IDP is received to exchange system a
（RequestReportBCSMEvent）；
Wherein, RRBE be used for notify a pairs of event related to calling of exchange system to be monitored, as monitor call whether road
The state done whether is in by failure, caller and whether is called in busy state etc..
Step 103, cornet platform then sends AC to exchange system a（ApplyCharging）；
AC is used to notify exchange system a to prepare to carry out charging to the calling.
Step 104, cornet platform sends FCI to exchange system a（FurnishChargingInformation）；
The FCI for indicating ticket caused by VPMN user is carried in FCI to identify（Such as character string 800130）, with instruction
Exchange system a caused tickets in the calling by the FCI identification records to user A（That is caller ticket）In.So, can make
The ticket is obtained after BOSS is provided to, BOSS can be identified according to the mark and be rejected the ticket.Because cornet platform can be right
The calling carries out charging, therefore above-mentioned processing mode can avoid the repetition charging to the calling.
Step 105, this step 105 may have following two implementations：
If user A is to initiate calling to user B true number, called true number is trombone by cornet platform
Code is carried on continuation（continue）Exchange system a is sent in this message；
If user A is to initiate calling to user B short codes, cornet platform is short according to the user B's included in IDP
Number, and the corresponding relation of the user B prestored short codes and user B true number, determine true number of user B
Called true number is simultaneously carried on connection by code（connect）Exchange system a is sent in this message；
Further, in step 105, after exchange system a receives continue or connect message, according to its carrying
User B true number, the signing that the attaching position register HLR belonged to user B true number inquires about user B believes
Cease T-CSI and user B positional information；
Step 106, exchange system a obtains user B true number according to the user B inquired signing information T-CSI
The cornet platform belonged to, and initial message IDP, the bearing call in the IDP are sent to the cornet platform by signaling system
Calling and called true number, i.e. user A and user B true number；
As it is assumed that user A and user B are the VPMN users for belonging to same group together, therefore in this step 106, exchange system
The cornet platform that the true number for the user B that a is determined is belonged to is still the cornet platform as shown in Figure 1, so as to hand over
The system a of changing is to send IDP to the cornet platform by signaling system.
Step 107, after cornet platform receives IDP, RRBE is sent to exchange system a；
Step 108, cornet platform sends AC to exchange system a；
Step 109, cornet platform sends connect message to exchange system a；
Include user B true number, and the GenericNumber in the connect message in the connect message
Special number 60 and user A number are carried in field（True number or short codes）.Wherein, GenericNumber words
Section in carry be user A true number or short codes be to be determined according to user B signing information.Specifically,
If the number that its caller identification is provided in the signing information of user is the true number of calling subscribe, then GenericNumber
What is carried in field is exactly user A true number；And if provided in the signing information of user based on the number of its caller identification
It is the short codes of user, then what is carried in GenericNumber fields is exactly user A short codes.
Step 110, exchange system a is after receiving by performing step 109 and the connect message of transmission, according to user B
True number, inquire about user B roaming number to the HLR of user B true number again, and according to user B roaming number
The positional information of code and user B, call proceeding request is sent to the exchange system b of user B roaming places（Such as initial address message
（Initial address message, IAM））, to ask exchange system b to meet user A to the user B callings initiated
It is continuous；
Wherein, in IAM comprising special number 60 and the user A for being shown in used in user B on user terminal
Number.Wherein, the effect of special number 60 is, instruction exchange system b by the special number 60 recorded exchange system b with
Family B caused tickets in this calling（I.e. called ticket）In.So, the ticket can be caused after BOSS is provided to,
BOSS can be identified according to the special number and be rejected the ticket.Due to cornet platform can to the calling carry out charging, therefore on
Repetition charging to the calling can be avoided by stating processing mode.In addition, exchange system b also sends the number of the user A in IAM
Shown to user terminal used in user B.
On the basis of above-mentioned steps, if follow-up call stops（Such as any one party on-hook in calling and called user）, then
Exchange system b call releases simultaneously report onhook event to cornet platform, so as to which cornet platform is directed to according to onhook event generation
The preferential ticket of this calling.
At present, above-mentioned handshaking procedure has problems in that：In order to avoid the user to having opened VPMN business（Following letter
Claim VPMN user）The repetition charging for the calling initiated, before the calling to VPMN user continues, caller VPMN user's
Multiple signaling can be carried out between exchange system and cornet platform to exchange, so as to cause the call delay of VPMN user long.Specifically
For, for non-VPMN user, typically within 6s, and for VPMN user, it is called its call proceeding time delay
The time delay that continues is then in 8s or so.
The content of the invention
The embodiment of the present invention provides a kind of call connection method and system applied to VPMN, to solve
There can be the problem of call proceeding time delay is longer using the call proceeding flow of VPMN user of the prior art.
The embodiment of the present invention also provides two kinds of exchange systems, a kind of message method and a kind of cornet platform device.
The embodiment of the present invention uses following technical scheme：
（Submit preceding supplement）
The embodiment of the present invention has the beneficial effect that：
By such scheme provided in an embodiment of the present invention, the call proceeding flow in the VPMN to prior art is realized

Embodiment
For the call proceeding flow solved using VPMN user of the prior art, to have call proceeding time delay longer
The problem of, inventor's flow that continued to existing call as shown in Figure 1 is studied.It has been investigated that in existing VPMN
Call proceeding flow has the characteristics that：
1st, compared to the calling of common cellphone user, VPMN user calls connect before more according to the signing of calling and called user letter
The step of breath is triggered, during which it is related to multiple signaling and exchanges, so as to cause the call delay of VPMN user long, customer service
Experience is poor.
2nd, the message triggered according to calling and called signing information mostly be in order to avoid the repetition charging to calling, such as
RRBE/AC/FCI etc..According to planning, the billing function of cornet platform may be weakened gradually, and the provider of ticket may change
For exchange system, i.e. billing and accounting system gathers ticket from exchange system, and eliminates the reliance on the ticket of cornet platform offer.In this background
Under, if not recycling cornet platform to generate ticket, it is contemplated that simplifying to message such as RRBE/AC/FCI.
3rd, at present, whether billing and accounting system is to be identified in the caller ticket provided by judging exchange system comprising FCI, with
And judge whether include special number in called ticket（Such as 60）To judge whether corresponding ticket belongs to produced by VPMN user
Ticket, if the judgment is Yes, then reject corresponding ticket.According to existing call proceeding flow, it is used in calling subscribe
In the case that short codes are called, and the calling number shown by the user terminal of called subscriber is also short codes, most throughout one's life
Into caller ticket in the calling number that includes be the true number of caller i.e. long code, and comprising called number then to be called short
Number；The calling number that includes be caller short codes in the called ticket of generation, and comprising called number then for it is called truly
Number.Under such circumstances, if billing and accounting system no longer gathers ticket from cornet platform, and the caller of exchange system offer is only relied on
Ticket and called ticket carry out the telephone expenses of counting user, then, it is necessary to by caller ticket and the number translated in called ticket into
Identical form（As be all converted to true number, or be all converted to short codes）Afterwards, could implement to carry out by comparing ticket
Preferential wholesale price, so as to which implementation process is comparatively laborious, and the more process resource of billing and accounting system can be expended.
Based on above-mentioned analysis, the embodiments of the invention provide a kind of call proceeding scheme applied to VPMN, by existing
There is the call proceeding flow in technology to carry out signaling optimization and reconstruct, realize and guaranteeing normally to carry out charging to calling
Under the premise of so that the call delay of VPMN user is no better than the call delay of non-VPMN user, also, is implemented using the invention
The scheme that example provides, can also avoid follow-up billing and accounting system from needing what is changed to the number in caller ticket and called ticket
Problem.
Embodiments of the invention are illustrated below in conjunction with Figure of description, it will be appreciated that implementation described herein
Example is merely to illustrate and explain the present invention, and is not intended to limit the invention.And in the case where not conflicting, the reality in this explanation
Applying the feature in example and implementation column can be combined with each other.
First, the embodiments of the invention provide a kind of call proceeding applied to VPMN as shown in Figure 2
Method, this method mainly include the following steps that：
Step 21, the first exchange system to cornet platform send the calling of VMPN Client-initiateds the true number of caller and by
Call out the numbers code；
The implementation of the step is similar with the implementation of the step 101 in the prior art shown in Fig. 1, no longer superfluous
State.
Step 22, the true number of caller and called number, generation that cornet platform is sent according to the first exchange system continue
Indicate message and sent to the first exchange system；
Optionally, the specific implementation of step 22 can be as follows：
The mark for the VPMN groups that cornet platform is belonged to according to the VPMN Subscriber Numbers prestored with VPMN Subscriber Numbers
Whether the corresponding relation of knowledge, the true number of caller and called number for judging the transmission of the first exchange system correspond to same VPMN collection
The mark of group；And when judged result is no, continue message is sent to the first exchange system；And in judged result be it is yes,
And when determining to exist the conversion to calling number or called number, include calling called true number is sent to the first exchange system
The connect message of code；It is yes in judged result, and when determining to be not present conversion to calling number or called number, to the
One exchange system sends continue message.Here continue message and connect message is described in step 22
Continue instruction message.
Optionally, when the called subscriber of the calling has opened caller identification business, can also be included in connect message
The calling number that the caller identification mode arranged with called subscriber matches.For example the caller identification mode that user is arranged is
It is required that the true number of display of calling, then the calling number to match with which is exactly the true number of caller；And if it is used for institute about
Fixed caller identification mode is requirement display of calling short codes, then the calling number to match with which is exactly caller cornet
Code.Wherein, the calling number that the caller identification mode arranged with called subscriber included in connect message matches can be with
It is that cornet platform is determined according to service profile corresponding with called number.
Step 23, when the instruction message that continues is connect message, the first exchange system wraps according in connect message
The called true number contained, determine the second exchange system of called subscriber position；And send this to the second exchange system and exhale
The the first call proceeding request cried；In addition, the first exchange system also performs the true number of caller and is called true number record
To the operation in the caller ticket of the calling；Wherein, the true number of caller is included in first call proceeding request and is called true
Real number；
It is finished after aforesaid operations, continues executing with step 24；
And when the instruction message that continues is continue message, the first exchange system determines according to the called number of the calling
Second exchange system of called subscriber position and the second call proceeding request that the calling is sent to the second exchange system；The
Two exchange systems continue after the second call proceeding request is received to the calling.In the embodiment of the present invention, first exchanges
System in the case where receiving continue message, if its also receive cornet platform transmission FCI, this calling charging by
Cornet platform is realized；And in this case, if exchange system a does not receive the FCI of cornet platform transmission, the charging of this calling
Realized by the first exchange system and the second exchange system of the calling that continues, and cornet platform is no longer given birth to for this calling
Into corresponding ticket.
It should be noted that the first exchange system is by the true number of caller and is called true number record to the master of the calling
Make the purpose in ticket be, can to include in the caller ticket that billing and accounting system subsequently gets at the first exchange system
There is the true number of caller and be called true number.
Optionally, as the master for including the caller identification mode arranged with called subscriber in the instruction message that continues and matching
When calling out the numbers yard, the calling number can be carried in the first call proceeding request and be sent to the second exchange system by the first exchange system
System.
Optionally, the caller identification mode arranged with called subscriber is included in the first call proceeding is asked to match
Calling number, and first call proceeding request, when be IAM message, the first exchange system sends this to the second exchange system
The specific implementation of IAM message can be：The caller identification mode phase that first exchange system will be arranged with called subscriber
After the calling number matched somebody with somebody is carried in the added field of the IAM message, is sent to the second exchange system and carry the calling number
IAM message.
Step 24, the second exchange system is after the first call proceeding request of the first exchange system transmission is received, to this
Calling is continued, and the true number of caller included during first call proceeding received is asked and called true number
In the called ticket that recorded the calling.
Optionally, the caller identification mode arranged with called subscriber is included in the first call proceeding is asked to match
Calling number when, the second exchange system can also be performed further：The calling number is sent to using called true number
User terminal shown.
By performing step 24, the second exchange system can record the true number of caller in called ticket and be called true
Number, so that it is true to include caller in the caller ticket that billing and accounting system is subsequently got at the second exchange system
Number and called true number.Due to billing and accounting system by performing step 23 described previously, can be caused to exchange system from first
Include the true number of caller in the caller ticket got at system and be called true number, therefore follow-up billing and accounting system is obtained
The calling caller ticket and called ticket in comprising the true number of caller and be called true number, so as to billing and accounting system without
The operation of number translated, which need to be performed, can also carry out preferential wholesale price, which simplifies the handling process of billing and accounting system, also save
Its process resource.
From the above method provided in an embodiment of the present invention, this method is the equal of in VPMN of the prior art
Call proceeding flow is simplified, so as to greatly reduce call delay.What deserves to be explained is although this process simplify existing
There is the call proceeding flow in technology, but use the call proceeding flow after simplifying to remain able to carrying out charging to calling
Under the premise of, successfully realize and calling is continued.
Corresponding to this method provided in an embodiment of the present invention, the embodiment of the present invention also provides a kind of application as shown in Figure 3
In VPMN call proceeding system, the system mainly includes cornet platform, the first exchange system and the second exchange system.Wherein,
The function of each part of the system is as follows：
Cornet platform, for sent according to the first exchange system VMPN Client-initiateds calling the true number of caller and
Called number, generation, which continues, to be indicated message and is sent to the first exchange system；
First exchange system, for sending the true number of caller of VMPN Client-initiateds calling to cornet platform and being called
Number；And when the instruction message that continues is connect message, according to the called true number included in connect message, it is determined that
Second exchange system of called subscriber position and the first call proceeding request that the calling is sent to the second exchange system；With
And by the true number of caller and true number record is called into the caller ticket of the calling；And it is in the instruction message that continues
During continue message, the second exchange system of called subscriber position is determined and to second according to the called number of the calling
Exchange system sends the second call proceeding request of the calling；
Second exchange system, after being asked in the first call proceeding for receiving the transmission of the first exchange system, to calling
Continued, and the true number of caller included during the first call proceeding is asked and called true number record to the calling
Called ticket in；And after the second call proceeding request is received, the calling is continued.
Optionally, when also including what the caller identification mode arranged with called subscriber matched in connect message
Calling number, while in the first call proceeding request when also including the calling number, the second exchange system can be also used for：By
The calling number included in one call proceeding request is sent to be shown using the user terminal for being called true number.Wherein
It should be noted that the calling number that the caller identification mode arranged with called subscriber matches be cornet platform according to quilt
Signing information corresponding to code of calling out the numbers and determine.
The application of such scheme provided in an embodiment of the present invention described further below in practice.
The concrete structure schematic diagram for being used to implement the system of such scheme in practical application is as shown in figure 4, main include handing over
Change system, cornet platform and signaling system.The concrete function of the system components is described below：
Exchange system（Mainly include MSC or SSP）, it is mainly used in after calling subscribe initiates calling, according to calling subscribe
Signing information trigger to cornet platform and send initial message IDP；And quilt is being obtained by the Signalling exchange with call platform
After being true number, the HLR belonged to called true number sends message and obtains the roaming number of called subscriber and be called
The positional information of user；And according to the positional information and roaming number of called subscriber, the exchange system to called subscriber position
System sends call proceeding request, and generation caller ticket.
Signaling system, mainly include signal switching unit, the Signalling exchange between exchange system and cornet platform is all logical
Cross the signaling system and realize.
Cornet platform, it is mainly used in preserving some relevant informations of VPMN user, for example, it is the true number of VPMN user, short
The caller identification mode that group's number that number, the true number of VPMN user and short codes are belonged to, VPMN user are arranged
And permissions data of VPMN user etc..When the called number included in the initial message IDP that exchange system reports is called short
During number, cornet platform can be according to the above-mentioned relevant information of the VPMN user of its preservation, it is determined that corresponding to the called short codes
Called true number, and judging that called subscriber is entitled to the calling carried out in VPMN according to the permissions data of called subscriber
When, the called true number determined is sent to exchange system.
It should be noted that be embodied as user open VPMN business system structure diagram it is as shown in Figure 5.System master
To include business system, exchange system and cornet platform.Based on the system as shown in Figure 5, it is open-minded that business system accepts user
The request of VPMN business and after opening the VPMN business of user, the signing information O-CSI of the VPMN user is sent to exchange system,
And instruction is sent to indicate that cornet platform stores true number of the above-mentioned relevant information of the user, the i.e. user to cornet platform
The caller identification mode that group's number that code, short codes, the true number of the user and short codes are belonged to, the user are arranged
And permissions data of the user etc..
Based on the system shown in Fig. 4, it is assumed that user A and user B has opened VPMN business, and cell where user A
User A signing information is preserved in exchange system a, the signing information without preserving user B, so as to which one typical
The call proceeding schematic flow sheet of VPMN user is as shown in fig. 6, comprise the steps：
Step 61, user A user terminal uses user A true number call user B in VPMN networks, then exchanges
After system a receives the calling, business is triggered according to the signing information O-CSI of caller, and sent out to cornet platform by signaling system
Initial message IDP is sent, the true number comprising user A and user B number in the IDP（Short codes or true number）；
Step 62, the information related to VPMN user that cornet platform stores according to itself, judges the user included in IDP
Whether A true number and user B true number correspond to same group's number（Also referred to as VPMN groups number）；If sentence
Disconnected result is yes, then performs step 63, otherwise performs step 64；
Specifically, cornet platform can first pass through the user A included in analysis IDP true number and obtain its ownership
VPMN groups number, and according to the short codes of the VPMN groups number and user B, perform from the VPMN groups number with belonging to
The operation of user B true number is searched in the corresponding relation of the short codes of the user of the group and true number, if searched
True number less than user B, then call failure notification message is sent to exchange system a, step is performed if it can find
63。
Step 63, cornet platform judges whether to need the conversion for carrying out Subscriber Number, and is judging to need to carry out user
During the conversion of number, connect message is issued to exchange system a, then performs step 65；Judging that user need not be carried out
During the conversion of number, continue message is issued to exchange system a, then performs step 65；
Wherein, the information carried in the genericnumber fields of the connect message is the incoming call with user B agreements
The calling number that display mode matches, for example it is assumed to be caller short codes, and the connect message
The information carried in destinationRoutingAddress fields is then user B true number.
Specifically, the scene that cornet platform judges to need to change Subscriber Number can include：
The caller identification mode that cornet platform is arranged according to user B, it is used when judging to need to initiate to call by user A
The short codes that true number translated is user A；Or user B of the cornet platform in IDP is judged called number is user B
Short codes, so as to need the true number that user B is converted to by the short codes being then forwarded to exchange system a in terms of realizing
Take；Etc..
And the scene that cornet platform judges that Subscriber Number need not be changed can include：
The caller identification mode that cornet platform is arranged according to user B, it is used when judging to initiate to call by user A
Short codes changed；Or the true number that user B of the cornet platform in IDP is judged called number is user B,
Without being sent to exchange system a after being changed to the true number；Etc..
Step 64, cornet platform issues continue message to exchange system a, then performs step 65；
Due to not corresponding to same group's number, i.e. user A in user A true number and user B true number
When being not belonging to same VPMN groups with user B, cornet platform need not perform the form of number for calling number and called number
Conversion, so as to which cornet platform issues continue message to exchange system a.Numbers of calling and called parties is not included in continue message.
Step 65, if what exchange system a received is connect message, according to user B true number from user B's
User B positions are inquired at HLR, and the true number of the user B in connect message is carried in IAM message, with
And after the calling number that the caller identification mode arranged with user B matches is carried in the added field of IAM message, will
IAM message is sent to the exchange system b of user B positions；Then proceed to perform step 66；
If what exchange system a was received is continue message, exchange system a is by the called subscriber by calling this
The analysis of number, the operation of call proceeding request will be sent to the exchange system of called subscriber position by performing.It is corresponding to hand over
System is changed after call proceeding request is received, calling is continued.It should be noted that exchange system a is being received
In the case of continue message, if it also receives the FCI of cornet platform transmission, the charging of this calling is real by cornet platform
It is existing；And in these cases, if exchange system a does not receive the FCI of cornet platform transmission, the charging of this calling is by exchanging
System a and the exchange system for the calling that continues are realized, and cornet platform is no longer for this calling generation ticket.
Step 66, exchange system b is after IAM message is received, and calling is continued, and by the add-word of IAM message
The calling number to match with the caller identification mode of user B agreements carried in section is sent to user B and shown.
Subsequently after the call has ended, exchange system a can record true number of user A in caller ticket of this calling
Code, the number that user A is called, user B true number；And exchange system b is then recorded in the called ticket of this calling
User A true number, user B true number and the calling number to match with the user B caller identification modes arranged.This
Sample, follow-up billing and accounting system record from exchange system a and exchange system b the caller ticket read and all in called ticket respectively
There are user A true number and user B true number, so as to which billing and accounting system is without performing the conversion behaviour to Subscriber Number form
Work can also be realized by comparing ticket to carry out preferential wholesale price.
Also, scheme provided in an embodiment of the present invention is used, is also created even if cornet platform for this calling
It is single, and billing and accounting system also obtain the ticket of cornet platform generation, follow-up billing and accounting system is also that can be put down by comparing cornet
Platform generation the ticket, exchange system a generation caller ticket and exchange system b generation called ticket and avoid repetition charging
, so the risk that repetition charging is carried out to calling is also not present.Preferably, if billing and accounting system no longer obtains the generation of cornet platform
Ticket, then also need not just perform above-mentioned comparison and operate.
Can be seen that it by the application process of scheme provided in an embodiment of the present invention in practice can realize to existing
The simplification of call proceeding flow in the VPMN of technology, so as to greatly reduce call delay.Although also, this process simplify
Call proceeding flow of the prior art, but use the call proceeding flow after simplifying to remain able to ensure to carry out to calling
The technique effect of call proceeding is successfully realized on the premise of charging.
Below by way of the explanation to different embodiments, other schemes provided in an embodiment of the present invention are specifically introduced.
