Abstract
The invention discloses a system and method for mixing a program-controlled switch dispatching desk and a soft switch dispatching desk and relates to the next generation of network technology. The system for mixing dispatching desks comprises a program-controlled exchange, a soft switch and a gateway, wherein the program-controlled exchange and the gateway are connected through an E1 channel and communicate with each other through a private protocol based on PRI (primary rate interface) protocol; the gateway and the soft switch are connected through an IP (Internet protocol) network and communicate with each other through an expanded SIP (session initiation protocol); and the gateway performs conversion between the private protocol based on PRI protocol and the expanded SIP. The system and the method provided by the invention have the beneficial effect that seamless fusion between the soft switch and the circuit program-controlled switch is finished with a very low cost, and the functions of a dispatching system can be enriched and the steady operation of the original dispatching system can be ensured. Moreover, no modification is performed on the program-controlled exchange, the waste of the dispatching resources is avoided, the deployment cost of the dispatching system is lowered, and smooth transition from a program-controlled dispatching system to a soft switch dispatching system is realized.
Description
Technical field
The present invention relates to next generation network technology, especially a kind of circuit program control scheduling platform and soft switch dispatching desk realized mixes system and method on the same group.
Background technology
In the communications applications of every profession and trade, disposed on a large scale based on the digital SPC exchange of circuit program controlled switch technology, especially in the dispatching communication field, the intrusion of dispatching desk, toll breakdown, function such as group calling, roll-call is widely used.But along with the communication technology, the especially continuous development of IP technology, the functional requirement that some are new like functions such as video conference, instant messages, can't realize on traditional circuit program controlled switch technology.
Next generation network (NGN) technology is replacement circuit program controlled switch technology gradually, becomes the mainstream technology of communication network.Soft switch (SoftSwitch) is the core of NGN, is a kind of functional entity, for next generation network provides the calling control of the business with real-time requirement and is connected control ability.The design philosophy of soft switch is: calling separates with service detach, carrying and control.Outside the fundamental sum supplementary service that soft switch support conventional telecommunication network provides, also support the business of various IP.
Have only the soft switch of utilization to replace circuit switching, could realize such as functions such as instant message, electronic whiteboard, video conferences.But the principle that the circuit programme-controlled exchange realizes and the agreement and the soft switch difference of use are very big; Have only and the seamless fusion of original dispatching patcher; The function of comprehensive compatible original dispatching patcher; Could guarantee to seamlessly transit to the soft switch dispatching patcher, and constantly promote the function of dispatching patcher based on Circuit-switched dispatching patcher.
Summary of the invention
Technical problem to be solved by this invention provides a kind of circuit program control scheduling platform of circuit programme-controlled exchange dispatching patcher dispatching desk and the seamless fusion of soft switch dispatching patcher and soft switch dispatching desk realized and mixes system and method on the same group.
For solving the problems of the technologies described above, one of technical scheme that the present invention taked is:
A kind of programme-controlled exchange dispatching desk and soft switch dispatching desk realized mixes system on the same group; Comprise based on the stored-program control exchange of PRI agreement with based on the SoftSwitch of inner proprietary protocol, it is characterized in that said system also comprises the gateway that carries out based on the Session Initiation Protocol conversion of PRI agreement and expansion; The Session Initiation Protocol that said SoftSwitch is provided with inner proprietary protocol and expansion carries out the module of bi-directional conversion; Said stored-program control exchange is connected through the E1 passage is two-way with gateway; Said gateway is connected through IP network is two-way with SoftSwitch.
For solving the problems of the technologies described above, two of the technical scheme that the present invention taked is:
A kind of said system of utilizing realizes that circuit programme-controlled exchange dispatching desk and soft switch dispatching desk mix method on the same group, is characterized in that may further comprise the steps:
A. on said stored-program control exchange, increase dispatching desk group group number and dispatching desk group membership A and B, wherein A is the local scheduling platform, and B is the far-end dispatching desk;
During the said dispatching desk group of customer call group number under the B. said stored-program control exchange, said stored-program control exchange carries out call analysis; When the customer call purpose is said local scheduling platform A, said stored-program control exchange sends the SETUP message in the PRI agreement to the local scheduling platform; When the customer call purpose is said far-end dispatching desk B, the USR TO USR message that said stored-program control exchange sends the ALERTING message of the carrying in the PRI agreement to said gateway;
C. after said gateway is received message, judge whether message into USR TO USR according to the message id field; When being USR TO USR message, convert thereof into the OPTION message in the Session Initiation Protocol of expansion, and the private data in the USR TO USR message is encapsulated in the OPTION message of Session Initiation Protocol of expansion, send to said SoftSwitch;
D. after said SoftSwitch is received said OPTION message; At the agreement Access Layer this message translation is become the soft switch inside story; And with the private data unit package in the OPTION message of Session Initiation Protocol of expansion in said inside story, send to the calling control of said SoftSwitch;
E. the calling of said SoftSwitch control triggers professional according to Service Point Trigger; The operation layer of said SoftSwitch judges whether to mixing professional on the same group; When being mixes on the same group when professional, the operation layer of said SoftSwitch notifies the calling control of said soft switch to initiate the message related to calls of inner proprietary protocol to said stored-program control exchange, and indicates this to call out to generation and answer; The agreement Access Layer that said message related to calls is transmitted to said soft switch is controlled in the calling of said SoftSwitch, is changed by it, sends the INVITE in the Session Initiation Protocol of expanding to gateway afterwards;
F. after said gateway is received said INVITE, this message conversion is become the SETUP message that comprises in the PRI agreement for answering message elements, and it is sent to said stored-program control exchange;
G. after said stored-program control exchange is received said SETUP message, send to said local scheduling platform A and to stop bell message in the PRI agreement, send the CONNECT message in the PRI agreement to said gateway;
H. after said gateway is received said CONNECT message, convert thereof into the 200OK message in the Session Initiation Protocol of expansion, send to said soft switch.
Adopt the beneficial effect that technique scheme produced to be: in soft switch, to handle to proprietary protocol; Accomplished the seamless fusion between soft switch and the circuit programme-controlled exchange with low-down cost; Both can enrich the function of dispatching patcher, guarantee original dispatching patcher even running again.And on stored-program control exchange, need not make any change, avoid the waste of scheduling resource, reduce the lower deployment cost of dispatching patcher, realize that the program control scheduling system seamlessly transits to the soft switch dispatching patcher.
