Description
Technical field
The present invention relates to a kind of Signaling System Number 7 message identification processing method and device that is used for Control on Communication and routing, specifically, under the prerequisite that does not change existing telecommunications network architecture, for (for example: the telecommunications network number portability business) implementing specific transactions, by control and treatment, realize Control on Communication and routing to the Signaling System Number 7 message content.
Background technology
No.7 signalling system has been widely used at field of telecommunications such as fixed line, intelligent call, mobile communication, short message services, the Signaling System Number 7 net is the core support net of telecommunications network, the introducing of each call and most of new business, all be unable to do without the support of Signaling System Number 7 net, especially the online number portability business of public telephone.
Telephone exchange is selected the path that can reach, and the process that the calling that the calling subscriber is initiated is connected to called switch and called subscriber is called call setup, and wherein the switch path selecting to arrive called switch is called routing (Routing).
As shown in Figure 1, typical local telephone calls, user A calling party B, switch is the called address of dialing according to user A, i.e. the number of user B realization routing, the route of the X of tandem exchange is selected to be connected to by end office (EO) 1, the X of tandem exchange selects to be connected to end office (EO) 2 according to the number of user B, end office (EO) 2 connecting subscribers participating B, like this, just finished being connected of user A and user B-through path A-B.Equally, user A calling party C-is through path A-C.Therefore, called address is the necessary condition of switch to call routing, the called address of change signaling message, and promptly called number will change and call out the path that connects; The calling number of change signaling message will change charge number on the calling number that is presented on the terminal called and the charge node.
The typical services of modal change number has the business that Number Portability, Call Forwarding and employing intelligent network are realized in telephone service.The NP business is mainly showing on the communication network aspect two: 1) number is constant behind the change geographical position: the user has changed behind the geographical position, when doing called and caller, still uses original telephone number; 2) number is constant behind the change network operator: under many network operators' environment, the user when doing called and caller, still uses original telephone number after having changed the network operator.Can be divided into telephone-moving number of staying and number portable again by the service feature division.
The existing method that changes number is divided into following several, because the NP business is typically to change the application of number, for convenience of explanation, every kind of method is limitation and the deficiency that example illustrates its use with the NP business all:
1, condition data is set on switch, finishes the change of number by call control program.This method is usually used in Call Forwarding services.As shown in Figure 1, the user B of end office (EO) 2 is provided with Call Forwarding to user C, when user A calling party B, calls out through path A-B, by end office (EO) 2 called address is changed to user C again, set up path B-C, form path A-B, B-C, be connected to user C, path A-B, B-C are communicated with by the call control program of end office (EO) 2, and be free of attachment to user B, for user A, the number of user B does not change.
When this method is used as the NP business, utilize calling of switchboard Call Forwarding Unconditional function.In having applied for the former NP number terminal of the user switch of NP business, Call Forwarding is set, this NP user's of incoming call call forward to the new digit that pre-establishes (new switch), therefore to this user's of incoming call calling, is not changed as called number.
But this method need take two number resources and to the Internet resources of former terminal station, increase the call proceeding time delay, the usage charges height, and what show during the NP customer call is NP user's new digit, the number portability in the time of can not realizing doing caller.This method realizes simple, but its inadequate natural endowment has limited its extensive use, and generally is only applicable to the telephone-moving number of the staying business of short-term.
2, at Service Switching Point (Service Switching Point-SSP) trigger condition is set, realizes the secondary addressing by the Service Control Point of intelligent network.SSP sends to SCP according to trigger condition with the call information of related service, finishes the change and the call proceeding control of calling number, called address by SCP, SSP according to the instruction of SCP with call proceeding to required destination.
When realizing that NP is professional,, be divided into dual mode according to the position of SSP in network:
One of: visit the NP database of concentrating by SSP at former terminal called switch.This method only requires incoming call is just visited the NP database when the user who has applied for the NP business breathes out with the user who has applied for the NP business, and this is a kind of minimal set implementation.When user applies NP when professional, need in the new switch at former terminaling exchange, NP user place and NP database, carry out the user data setting.NP user is arrived in incoming call: in former terminaling exchange, if former terminaling exchange is SSP, then need to be provided with the calling of incoming call to this user triggered, if do not possess the SSP function at former terminaling exchange, to this NP user's of incoming call calling then by former terminaling exchange with Call Forwarding to the switch that possesses the SSP function, SSP realizes the translation of called address by Signaling System Number 7 visit NP database, finishes calling; NP user breathes out: in the new switch at NP user place, as this switch is SSP, the exhalation that then needs to be provided with this user triggers, if this switch does not possess the SSP function, adopt the access code mode with call proceeding to the switch that possesses the SSP function, SSP realizes the translation of calling number by Signaling System Number 7 visit NP database, finishes calling.
This method need take two number resources and to the Internet resources of SSP, increased the call proceeding time delay, need the support of intelligent network, need in the new switch at former terminaling exchange, NP user place and NP database, carry out the user data setting, the maintenance operation complexity, owing to build and the cost of use height, its extensive use has been subjected to certain limitation.This method is the method to realizing that number portability is recommended in People's Republic of China's communication industry standard " number portability business specification requirement (YD/T 1124/2001) ".
Two: the switch of making a start, toll switchbroad and gateway exchange all increase the SSP function and visit distributed NP database by Signaling System Number 7.This method requires the per call in incoming call local network and the local network is all visited the NP database, this is a kind of desirable maximum set implementation, its principle and mobile communication are similar, be that the per call switch of making a start is all inquired NP database (HLR in the mobile communication), determine caller and called physical number and feature, finish calling.This method is seen present huge communication network, needs transform whole local network, and investment is big, performance difficulty.
