Abstract
The invention discloses a method for realizing coexistence and mutual backup of a session initiation protocol (SIP) and an integrated service digital network (ISDN) protocol aiming at a dispatching desk in the field of communication dispatching. By the method, a set of hardware equipment can be connected with a program-controlled switch and a softswitch at the same time, and calling with the program-controlled switch and calling with the softswitch can be established at the same time, so that when communication connection with the program-controlled switch or the communication connection with the softswitch fails, the communication connection with the other switch can be maintained, and safety and reliability of using the dispatching desk are enhanced.
Description
Technical field
The invention belongs to communication scheduling field, relate in particular to a kind of not only can connect SoftSwitch but also can connect digital SPC exchange for dispatching desk, realize SIP and ISDN agreement coexists and mutually redundant method.
Background technology
Dispatching communication equipment is a kind of communication equipment that provides production scheduling or commander to control for enterprises or group user.A series of function of voice communication such as dispatching desk can realize incoming call, exhalation, group calling, meeting, intrusion, toll breakdown.This system is widely used in the professional dispatching communication fields such as electric power, coal, oil, army, track traffic, government emergency.
The current main mode of dispatching services is based on circuit-switched technology.Due to developing rapidly of IP network, the back scheduling business based on Softswitch technology is also in development.Due to the professional requirement of scheduling, soft switch can not replace circuit switching and individualism immediately, and therefore, the fusion of two kinds of technology will exist in a very long time.Dispatching desk, as most important end product in dispatching patcher, must can be good at combined circuit exchange and Softswitch technology.Summary of the invention
The object of the invention is to avoid the deficiency in above-mentioned background technology, and the one proposing realizes SIP for dispatching desk and ISDN agreement coexists and mutually redundant method
The object of the invention is to be achieved through the following technical solutions:
One realizes SIP for dispatching desk and ISDN agreement coexists and mutually redundant method, it is characterized in that: the method realizes by means of the dispatching desk being comprised of ISDN protocol adaptation module, Session Initiation Protocol adaptation module, link data processing module, call state machine module, Call Control Block, external device management module, external equipment, is specially:
The breath step of collecting mail is:
(1) from isdn interface, receive circuit calling information, enter ISDN protocol adaptation module and carry out protocol adaptation, then increase isdn call subscript, proceed to link data processing module; From network interface, receive calling network message, enter Session Initiation Protocol adaptation module and carry out protocol adaptation, then increase SIP and call out subscript, also proceed to link data processing module;
(2) link data processing module, is all forwarded to call state machine module by the ISDN information of receiving or SIP information;
(3) call state machine module is first resolved message header in message, then judges whether sip message, if sip message is called out rule parsing message body according to SIP, otherwise according to isdn call rule parsing message body; After parsing, revise the state of call state machine, and the message header after resolving and SIP message related to calls body or message header and isdn call message body are converted to BPORT message format issue Call Control Block.
(4) Call Control Block is sent the message of income into BPORT(Tone Via passage) state machine, the business that judges this message activation is the business that ISDN and SIP support, or both incompatible business; If the business of all supporting is unified realization, if incompatible business realizes respectively according to SIP trafficwise or ISDN trafficwise; After realization, revise the state of BPORT, and send and upgrade state notifying to peripheral equipment management module;
(5) peripheral equipment management module is received after state update notification, notifies corresponding external device status to upgrade;
(6) peripheral hardware is received after update notification, upgrades current state;
Photos and sending messages step is:
(1) peripheral hardware is reported to peripheral equipment management module by new element;
(2) peripheral equipment management module is converted to service request by the action of peripheral hardware, reports to Call Control Block;
(3) Call Control Block is sent the service request of receiving into BPORT state machine, and according to the state of current device, service request subscript is set, and then inspection type of service, if ISDN and SIP be the business of compatibility, unified realization, if the business that both are incompatible, realizes according to SIP call business implementation or isdn call business realizing mode respectively.After business realizing, upgrade BPORT state, more new state of notice peripheral hardware, then sends message call state machine resume module;
(4) call state machine module is sent message into call state machine, then Versatile content is encapsulated as to message header part, then according to message subscript, other content is encapsulated into message body according to SIP calling rule or isdn call rule.After encapsulation, message is sent to link data processing module;
(5) link data processing module, by the message of receiving according to message subscript, is sent to ISDN protocol adaptation module or Session Initiation Protocol adaptation module by message;
(6) ISDN protocol adaptation module is carried out adaptation by the message of receiving according to ISDN agreement, then sends to isdn interface.Session Initiation Protocol adaptation module is carried out adaptation by the message of receiving according to Session Initiation Protocol, then sends to network interface.
Wherein, peripheral equipment management module is only managed a set of external equipment, no matter is ISDN type or SIP type call, and this equipment is that ISDN and SIP share.
Wherein, link data processing module is as unique gateway of the each module in dispatching desk inside and ISDN and Session Initiation Protocol; Link data processing module is responsible for the Link State of maintenance schedule platform and stored-program control exchange and SoftSwitch simultaneously.
The present invention, compared with method before, has realized and has only used a set of hardware device to realize to be connected with SoftSwitch with stored-program control exchange simultaneously.Use this equipment can set up simultaneously with the calling of stored-program control exchange and with the calling of SoftSwitch, make after breaking down with being connected of a side, can also keep and the opposing party's communication connection, strengthened the security reliability that dispatching desk uses.
