Specific embodiment
Technical solution in order to enable those skilled in the art to better understand the present invention, with reference to the accompanying drawing and specific embodiment party
Formula to the group user number of taking of the present invention turn net communication means,
Media Gateway Control Function entity, Gateway Mobile Switching Center, service control server are described in further detail.
According to an aspect of an embodiment of the present invention, the embodiment of the invention provides a kind of group user numbers of taking to turn the logical of net
Letter method.
Referring to Fig. 1, Fig. 1 is the process for the communication means that a kind of group user number of taking provided in an embodiment of the present invention turns net
Schematic diagram.
As shown in Figure 1, being called when the group user that the number of taking turns net is used as in IMS domain, and caller is the group user in the domain CS
When, this method comprises:
S1: calling invitation message that Media Gateway Control Function entity is sent in response to Gateway Mobile Switching Center and called
Corresponding identity identification information sends the name authority pointer note for carrying inquiry called number to telephone number mapping server
The inquiry request of record.
When Media Gateway Control Function entity receives the calling invitation message of Gateway Mobile Switching Center transmission and is called
When corresponding identity identification information, then inquiry request is sent to telephone number mapping server, which is to carry inquiry
The inquiry request of the name authority pointer record of called number.
Before this step, include the steps that call subscriber terminal, base station and Gateway Mobile Switching Center establish connection.Tool
Body:
When calling subscriber dials the corresponding called user terminal of called subscriber by call subscriber terminal, calling subscriber is whole
It holds to base station initiating business request message, base station is to Gateway Mobile Switching Center forwarding service request message.Gateway mobile switch
Strategy of the center based on operator, establishes the communication connection between three.
After establishing communication connection, calling subscriber sends calling invitation message, base station to base station by call subscriber terminal
Calling invitation message is forwarded to the Gateway Mobile Switching Center of caller.
It should be noted that further including judging whether calling number and called number belong to same group before S1
Step, and the step of judging specifically is completed by the Service control center of caller.Specifically:
The Gateway Mobile Switching Center of caller will exhale behind the Service control center for determining caller according to call request message
The Service control center for making request message be sent to caller.The Service control center of caller is based on call request message and obtains caller
Number and called number, and judge whether calling number and called number belong to same group.When learning calling number and called
After number belongs to same group, connection message can be sent in the gateway mobile switch of caller by the Service control center of caller
The heart.The operation such as calling invitation message is sent so that the Gateway Mobile Switching Center of caller executes.And the Service control center of caller
The corresponding ticket of call request message is identified.Meanwhile the Service control center of caller can also be mobile to the gateway of caller
Switching centre sends EEBE message (i.e. identified event), and sends AC message to the Gateway Mobile Switching Center of caller and (call
Charging message), and send FCI message to the Gateway Mobile Switching Center of caller and (it is slotting into the station message recording to be used to indicate MSC/SSP
Enter sorting mark message), so as to caller Gateway Mobile Switching Center according to AC message and FCI message trigger SSP (i.e. signaling
Exchange point), so that related content is added in this calling ticket in service switch point.Specifically, when belonging to same group, then
SSP does not converse to this according to corresponding ticket writing and carries out charging processing.
S2: Media Gateway Control Function entity receives called pair that telephone number mapping server is fed back based on inquiry request
The uniform resource identifier answered, and called call conversation control function entity is determined according to uniform resource identifier.
It is understood that after telephone number mapping server receives inquiry request, it can be to media gateway controlling function
It can the corresponding uniform resource identifier of Entity feedback called number.
Wherein, uniform resource identifier carries operator identifier and province label, and the called number carried is to route
Code beginning.
S3: Media Gateway Control Function entity generates target call according to calling invitation message and identity identification information and asks
It asks.
In a kind of technical solution in the cards, S3 is specifically included:
S3-1: Media Gateway Control Function entity obtains calling number and additional caller number in identity identification information.
Obtain the calling number CallingPartyNumber and additional caller number in identity identification information
AdditionalPartyNumber。
S3-2: Media Gateway Control Function entity modifies the domain FROM in calling invitation message, and base based on calling number
The domain PAI in additional caller number modification calling invitation message, obtains target call request.
S4: target call request is sent to called call session control function reality by Media Gateway Control Function entity
Body.
In a kind of technical solution in the cards, after S4, further comprise the steps of:
S5: Media Gateway Control Function entity is received called call conversation control function entity and is requested based on target call
The modified target call request of feedback.Wherein, the request of modified target call is by service control server according to connecing
The target call request that called call conversation control function entity is sent is received, and according to the configuration information of current caller identification
Modification target call is requested.
S6: the request of modified target call is sent to and is called corresponding called subscriber by Media Gateway Control Function entity
Terminal.
