For making the purpose, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing specific embodiments of the invention are elaborated.At this, illustrative examples of the present invention and explanation thereof are used for explanation the present invention, but not as a limitation of the invention.
The embodiment of the invention provides a kind of flow control methods, device and system, and described methods, devices and systems are not only applicable to the cdma network system, is equally applicable to the GSM network system, is elaborated below in conjunction with accompanying drawing.
Embodiment 1
Present embodiment provides a kind of calling flow control method.Calling mobile exchanging center (caller MSC) is according to the method for present embodiment, and the calling when called equally can the priority treatment superuser be done in the calling when not only can the priority treatment superuser doing caller.
Need to prove that at this mobile switching centre in the existing communication agreement (MSC) and VLR Visitor Location Register (VLR) are two logic entities, establish but close in actual use, close the MSC/VLR that establishes and to abbreviate MSC as.Alleged in embodiments of the present invention mobile switching centre is similarly the mobile switching centre that has integrated VLR.
With reference to the call flow diagram that is illustrated in figure 1 as in the present embodiment, this method comprises the steps:
Step 110, the receipt of call signaling.
The embodiment of the invention is not only applicable to mobile phone users and calls out mobile phone users, be equally applicable to the PSTN terminal use and call out mobile phone users, therefore described call signaling can be the call signaling from base station controller (BSC or RNC), also can be the call signaling from PSTN or other mobile networks.
Step 120 sends route information query request to called attaching position register (HLR).
Step 130, receive the response message (routing iinformation is looked into response message) that called HLR is returned, carry the precedence information of terminal called and the roaming number that called HLR is obtained from called mobile switching centre (called MS C, or title called end office MSC) in this response message.
The roaming number that called HLR can adopt the flow process of prior art to obtain from called MS C, for example, called HLR sends roaming number to called MS C and distributes request, after called MS C receives roaming number distribution request, distribute roaming number, be sent to called HLR by the roaming number assignment response message.
Step 140 determines whether this time of priority treatment calling according to the precedence information of calling terminal and the precedence information of terminal called.
For example, can determine comprehensive priority information according to the precedence information of calling terminal and the precedence information of terminal called, and determine whether this time of priority treatment calling according to described comprehensive priority.
Described comprehensive priority can have multiple expression mode, for example, priority higher in can the priority with the priority of calling terminal and terminal called is as comprehensive priority, in other words, can determine whether this time of priority treatment calling according to higher priority in the priority of the priority of calling terminal and terminal called.But the embodiment of the invention is not limited to this, if this comprehensive priority can map out in calling terminal and the terminal called one of at least make superuser the time precedence information, the expression mode of this comprehensive priority is all within the scope of the invention.
By as above step, caller MSC just can obtain the priority of terminal called, and the calling when called equally can the priority treatment superuser be done in the calling when so just not only can the priority treatment superuser doing caller.Superuser is done caller or when called like this, can corresponding priority treatment, comprise using being the superuser reserved resource, and processings that continue of the resource of superuser conversion domestic consumer, Flow Control etc. is not carried out in calling to superuser.
Embodiment 2
The embodiment of the invention also provides a kind of calling flow control method.Called MS C can just carry out flow control according to this method when distributing roaming number, thereby reduces failed calls taking system resource.
With reference to Fig. 2, this method comprises:
Step 210, the roaming number that receives from called attaching position register distributes request, carries the precedence information of calling terminal in this request.
The precedence information of described calling terminal can be provided to called HLR by route information query request by caller MSC, for example: if calling terminal is the terminal of mobile communications networks such as CDMA or GSM, the precedence information of calling terminal can obtain and offer called HLR from caller HLR by caller MSC when calling terminal carries out the position registration; If calling terminal is the PSTN terminal, the precedence information of calling terminal can obtain and offer called HLR by caller MSC from the call signaling that receives.
After called HLR is obtained the precedence information of calling terminal, be carried in roaming number and distribute in the request.
If called HLR also is simultaneously the caller HLR under the calling terminal, also record the precedence information of calling terminal this moment in the called HLR simultaneously, so called HLR can be directly be carried at roaming number with the precedence information of the calling terminal of self record and distributes and ask.
Whether step 220 determines the priority allocation roaming number according to the precedence information of the precedence information of calling terminal and terminal called.
For example, can determine whether the priority allocation roaming number according to higher priority in the priority of the priority of calling terminal and terminal called, but the embodiment of the invention is not limited to this.
Owing to consider that the precedence information of calling terminal and the precedence information of terminal called carry out flow control simultaneously, the calling when called again can the priority treatment superuser be done in the calling when therefore can the priority treatment superuser doing caller; And present embodiment is just to carry out flow control when assignment numbers, thereby reduces failed calls taking system resource.
Embodiment 3
Calling flow control method schematic flow sheet when Fig. 3 calls out the mobile subscriber for mobile subscriber in the cdma system of the embodiment of the invention, as shown in Figure 3, this method comprises:
Step 310, caller MSC receives the call signaling that caller BSC sends.
Step 320, caller MSC(or title originating switch MSC) send route information query request (as location request message LOCREQ) to called HLR.
Alternatively, caller MSC can carry the precedence information of calling terminal in route information query request, and described precedence information can be the identifier, parameter etc. of indication priority, but is not limited to this.This precedence information also can be sky, and for sky then gives priority to level for common, namely the calling terminal user is domestic consumer.
If calling terminal is the terminal of mobile communications networks such as CDMA or GSM, the precedence information of calling terminal can be obtained from caller HLR when calling terminal carries out the position registration by caller MSC; If calling terminal is the PSTN terminal, the precedence information of calling terminal can be obtained from the call signaling that receives by caller MSC.
If it also is simultaneously the caller HLR under the calling terminal that caller MSC finds called HLR, owing to also record the precedence information of calling terminal this moment in the called HLR simultaneously, therefore also can in route information query request, not carry the precedence information of calling terminal.
Step 330, called HLR receives route information query request, sends roaming number to called MS C and distributes request (as route request information ROUTREQ), the priority of carrying calling terminal.
Be carried at roaming number and distribute the precedence information of the calling terminal in the request from route information query request, to obtain for called HLR, perhaps when called HLR is caller HLR simultaneously, obtain from self.
Called MS C comprehensively Calling Side priority, the callee side priority comprehensive priority that obtains to call out (this comprehensive priority can be higher priority in the priority of the priority of calling terminal and terminal called, but be not limited thereto), and determine whether to distribute roaming number according to described comprehensive priority.During called MS C self overload, the called MS C low calling of refusal part comprehensive priority earlier, and be preferably the high call distribution roaming number of comprehensive priority.
For example, when called MS C self transships, roaming number when domestic consumer is called out by the domestic consumer that called MS C can refuse some in proportion distributes request, and superuser, superuser are called out domestic consumer, the roaming number when superuser is called out by domestic consumer distributes request and the priority treatment superuser is called out.Like this, when assignment numbers, just carry out flow control, thereby reduced failed calls taking system resource.
Alternatively, if called MS C has distributed roaming number, then execution in step 350.
Step 350, called MS C wherein carries roaming number and terminal called priority return roaming number assignment response message (as route requests response message routreq) to called HLR.
Step 360, called HLR is given caller MSC by route information query response message (as position request response message locreq), to return roaming number, carries terminal called priority simultaneously.
For example, when caller MSC self transships, the calling that the priority treatment superuser participates in, comprise using and be the superuser reserved resource, the processing that continues of the resource of superuser conversion domestic consumer, Flow Control is not carried out in calling to superuser, refuses the low calling of a part of comprehensive priority in proportion, thus the high calling of priority treatment comprehensive priority.
Step 380-390, caller MSC is at the calling of priority treatment, by one or more MSC of tandem exchange to call signaling (as call request message) between called MS C forwarding office, and in station to station call signaling (as call request message), carry comprehensive priority, namely transmit comprehensive priority at interoffice.
The MSC of tandem exchange, called MS C receive call request, determine whether to carry out flow control according to the priority in the message in conjunction with self-ability.Because what the MSC of tandem exchange, called MS C received is the comprehensive priority that combines calling and called priority, can carry out priority treatment to calling according to comprehensive priority, comprise using and be the superuser reserved resource, processings that continue of the resource of superuser conversion domestic consumer, Flow Control etc. is not carried out in calling to superuser.In the present embodiment, priority is the comprehensive priority that combines caller and called users.In the prior art, the priority of carrying in the call request is caller priority, can only the priority treatment caller be the situation of superuser.As long as present embodiment can have one to be the situation of superuser in the priority treatment caller and called users.
In above-mentioned steps 350, in the message (as routreq message) of called HLR transmission, also can not carry the priority of terminal called, and the priority of terminal called is added in the route information query response message (as locreq message) in step 360 by called HLR.
Fig. 4 is the call flow schematic diagram in the present embodiment, and this flow process comprises:
Step 405, whether called MS C determines the priority allocation roaming number according to calling terminal priority and terminal called priority.
For example, can be when calling flow be big, called MS C can be preferably calling (as the calling between the calling between the superuser, domestic consumer and the superuser) the distribution roaming number that the privileged trading user participates in, and the route requests of the calling between the refusal part domestic consumer, thereby reduce failed calls taking system resource as far as possible.
As another embodiment of the present invention, in the route requests response message of above-mentioned steps 406, also can not carry the priority of terminal called, and in step 407, directly be added in the position request response message by the priority of called HLR with terminal called.
Step 409, caller MSC is that the priority of terminal called is determined comprehensive priority according to the priority of calling terminal, and determines whether that according to comprehensive priority priority treatment calls out.
In this step, but the high calling of caller MSC priority treatment comprehensive priority, and according to the low calling of self-bearing capacity refusal comprehensive priority.
Follow-up flow process can same prior art, for example:
The comprehensive priority of also determining in the portability embodiment of the invention wherein, BSC calls out superuser according to priority and carries out priority treatment, comprise using being the superuser reserved resource, processings that continue of the resource of superuser conversion domestic consumer, Flow Control etc. is not carried out in calling to superuser.
As can be known above-mentioned, the calling when called also can the priority treatment superuser be done in the calling when present embodiment not only can the priority treatment superuser be done caller; And the embodiment of the invention can just be carried out flow control before roaming number distributes, thereby takies the resource of whole system less as far as possible.
Embodiment 4
Fig. 5 is the calling flow control method schematic flow sheet when PSTN (PSTN) is called out the mobile subscriber in the cdma system of the embodiment of the invention, and as shown in Figure 5, this method comprises:
Step 510, PSTN (PSTN) customer call mobile subscriber, to GMSC (gateway mobile switching center) (GMSC, claim gateway exchange or mobile network gateway exchange again, existing MSC generally has the function of GMSC) the transmission call signaling, as send IAM message, carry the priority of the calling terminal of PSTN side in this IAM message.
Step 520, GMSC among caller MSC(such as Fig. 5) send route information query request (as location request message LOCREQ) to called HLR, carry the precedence information of calling terminal in the request.
Step 530, called HLR receives route information query request, sends roaming number to called MS C and distributes request (as route request information ROUTREQ), the priority of carrying calling terminal.
Called MS C is the comprehensive priority of Calling Side priority, callee side priority acquisition calling comprehensively, and determines whether to distribute roaming number according to described comprehensive priority.During called MS C self overload, the called MS C low calling of refusal part comprehensive priority earlier, and be preferably the high call distribution roaming number of comprehensive priority.
For example, when called MS C self transships, roaming number when domestic consumer is called out by the domestic consumer that called MS C can refuse some in proportion distributes request, and superuser, superuser are called out domestic consumer, the roaming number when superuser is called out by domestic consumer distributes request and the priority treatment superuser is called out.Like this, when assignment numbers, just carry out flow control, thereby reduced failed calls taking system resource.
Step 550, called MS C wherein carries roaming number and terminal called priority return roaming number assignment response message (as route requests response message routreq) to called HLR.
Step 560, called HLR is given caller MSC by route information query response message (as position request response message locreq), to return roaming number, carries terminal called priority simultaneously.
For example, when caller MSC self transships, can refuse the low calling of a part of comprehensive priority in proportion, and the high calling of priority treatment comprehensive priority.
Step 580-590, caller MSC send call request message by one or more MSC of tandem exchange to called MS C, and carry comprehensive priority in call request messages at the calling of priority treatment, namely transmit comprehensive priority at interoffice.
The MSC of tandem exchange, called MS C receive call request, determine whether to carry out flow control according to the priority in the message in conjunction with self-ability.In the present embodiment, priority is the comprehensive priority that combines caller and called users, as long as therefore can have one to be the situation of superuser in the priority treatment caller and called users.
In above-mentioned steps 550, in the message (as routreq message) of called HLR transmission, also can not carry the priority of terminal called, and the priority of terminal called is added in the route information query response message (as locreq message) in step 560 by called HLR.
Fig. 6 is call flow schematic diagram concrete in the present embodiment, and this flow process comprises:
Step 601, the PSTN network user is to caller MSC(GMSC) send call signaling (as IAM message), carry Calling Side priority in the message.
Step 602, GMSC sends location request message (LOCREQ) to called HLR, with to called HLR inquiry route, asks called positional information, and this location request message is carried the priority of calling terminal.
Step 603, called HLR sends route request information (ROUTREQ) to called MS C, and to obtain called roaming number from called MS C, this route request information is carried the priority of calling terminal.
Step 604, whether called MS C determines the priority allocation roaming number according to calling terminal priority and terminal called priority.
Step 605, if the priority allocation roaming number, called MS C returns roaming number by route requests response message (routreq), and carries the priority of terminal called at the route requests response message.
Step 606, called HLR returns to caller GMSC to roaming number by position request response (locreq), and carries the priority of terminal called in position request response.
As another embodiment of the present invention, in the route requests response message of above-mentioned steps 605, also can not carry the priority of terminal called, and in step 606, directly be added in the position request response message by the priority of called HLR with terminal called.
Step 607, caller GMSC is that the priority of terminal called is determined comprehensive priority according to the priority of calling terminal, and determines whether that according to comprehensive priority priority treatment calls out.
In this step, but the high calling of caller GMSC priority treatment comprehensive priority, and according to the low calling of self-bearing capacity refusal comprehensive priority.
Step 608, if priority treatment should be called out, then caller GMSC analyzes the roaming number that called HLR is returned, send initial address message (IAM to the MSC of tandem exchange, Initial Address Message), to call out connection, this IAM message is carried roaming number and comprehensive priority information, so that the MSC of tandem exchange priority treatment superuser is called out.
Step 609, the MSC of tandem exchange analyzes roaming number, sends initial address message (IAM) to called MS C, and this IAM message is carried roaming number and comprehensive priority information, so that called MS C priority treatment superuser is called out.
Follow-up flow process can same prior art, for example:
Step 610, called MS C sends paging request message (Paging Request) to called BSC.
Step 611, called BSC sends page-response message (Paging Response) and gives called MS C;
Step 612, called MS C sends assignment request message (Assignment Request) to called BSC, the assignment circuit between channel and called MS C and called BSC of eating dishes without rice or wine.
Step 613, after the carrying that called BSC finishes the circuit between channel and called MS C and called BSC of eating dishes without rice or wine was set up, called BSC sent assignment to called MS C and finishes message (Assignment Complete).
Step 614, called MS C sends the complete message in address (ACM, Address Complete) to the MSC of tandem exchange.
Step 615, the MSC of tandem exchange sends the complete message in address (ACM) to caller GMSC.
Step 616, caller GMSC sends the complete message in address (ACM) to the calling terminal of PSTN network.
Step 617, after terminal called was replied, called BSC sent connection message (Connect) to called MS C.
Step 618, called MS C sends response message (ANM) to the MSC of tandem exchange.
Step 619, the MSC of tandem exchange sends response message (ANM) to caller GMSC.
Step 620, caller GMSC sends response message (ANM) to the calling terminal of PSTN network.
As can be known above-mentioned, the calling when called also can the priority treatment superuser be done in the calling when present embodiment not only can the priority treatment superuser be done caller; And the embodiment of the invention can just be carried out flow control before roaming number distributes, thereby takies the resource of whole system less as far as possible.
