Abstract
The invention discloses a signaling link backuping method for a soft-switch system, which comprises the steps that: A, a communication server sends a dialogue to each media gateway regularly, wherein the dialogue is monitored by a timer; B, if the timer is overtime or the dialogue is interrupted, the communication server begins to search an idle savior media gateway; C, an internal modem of the savior media gateway calls a separated media gateway by using a predefined number; D, the separated media gateway is re-started in a backup link mode, only activates a pre-designated backup access, and waits on the access in a receiving mode; and E, a call on the backup access is sent to the internal modem of the savior media gateway and a dialogue with the communication server is re-established so as to re-receive the call. By using the method disclosed by the invention, the reliability of a soft-switch system is improved; and under the condition that an IP bearer network of an original system is interrupted, the signaling interaction between the communication server and a remote branch mechanism can be maintained, so that a limited number of telephone sets on the remote branch mechanism still run normally, thereby reducing the influence as far as possible.
Description
Technical field
The present invention relates to the networking mode of voice exchange communication system, specifically is a kind of signaling link backup method between a kind of soft switchcall server central site and the remote branch.
Background technology
Communicating by letter between the communication server and the remote branch is to be bearer path with the IP link in the traditional soft switching system, when IP tunnel breaks down, not only voice channel interrupts, and also interruption together of signaling channel, will cause remote branch can not normally finish communication work.When the IP link between the remote branch and the communication server at central site breaks down, if do not carry out the backup of signaling link, remote branch will can't communicate by letter with the communication server, in case signaling can't be obtained, remote branch will work normally, and all conversations can disconnect and can't set up new connection.Therefore, the communication reliability of traditional soft switching system is difficult to satisfy the system that disaster recovery is had relatively high expectations.
Summary of the invention
The objective of the invention is to, overcome in the prior art, when the IP of the communication server and remote branch bearing link takes place to interrupt, the Signalling exchange of the communication server and remote branch will be lost, thereby have influence on this problem of operate as normal of remote branch, propose a kind of backup method of signaling link.
Technical scheme of the present invention is as follows:
A kind of signaling link backup method of soft switchcall server comprises the steps:
A. the communication server regularly sends dialogue to each media gateway, and dialogue is monitored by timer;
B. if timer expired or dialogue are interrupted, then the communication server begins to search for idle savior's media gateway;
C. the inside modem of savior's media gateway uses the media gateway that predefined number call separates;
D. the media gateway of Fen Liing is restarted with standby link mode, only activates preassigned standby access, and waits for receiving mode on this inserts;
E. the calling in the standby access sends to the inside modem of savior's media gateway, rebulids call accepted again with the dialogue of the communication server.
Beneficial effect of the present invention is, adopt the wherein a kind of mode of traditional PSTN network (or E1 link) as the backup of soft switchcall server signaling with equal effect, make soft switchcall server improve the degree of reliability of system, the influence when system is broken down reduces.The present invention also can adopt and carry out networking with original switching network or adopt original transmission link (as the E1 link) to carry out signaling link backup, the Signalling exchange problem when effectively having avoided the communication server and the media gateway IP of remote branch interrupted communication link to soft switchcall server.Saved the cost of investment of system signaling communication channel.

Fig. 1 is signaling backup principle schematic.
Embodiment
Method of the present invention can be applicable to the signaling between the media gateway on backup communication server and the remote site, the communication server monitors link condition between it and each media gateway by one " maintenance active state " dialogue, " maintenance active state " dialogue is all monitored by a timer at every turn, work as timer expired, will detect remote equipment and interrupt.If this talks with interruption, will point out the communication server that fault has taken place.The communication server uses the modem in the public telephone network to attempt connecting the media gateway of separating immediately.
For " signaling link backup " function, have following several media gateway type:
Savior's media gateway: this type of media gateway can be provided with calling to the media gateway of separating.Savior's media gateway is arranged in communication server website (being connected by LAN).Each savior's media gateway can only back up a media gateway at every turn, because it has only a modem.
The media gateway that can save: on its nominal IP link, move, but the media gateway that backs up when being configured to network failure occur.
The media gateway of being saved: the media gateway that when its nominal IP link breaks down, is effectively backed up.
Behind " maintenance active state " timer expired, it will state that nominal link breaks down and starts reserve link activation.
Activation will be carried out in the following manner:
At communication server end:
Savior's media gateway that search is idle.
The media gateway that the inside modem of savior's media gateway will use predefined number call to separate.
By media gateway one end saved:
The media gateway of separating is restarted execution after observing nominal link and breaking down.Therefore, all ongoing callings all will be lost.
The media gateway of separating will be restarted with " reserve link " pattern, and it only activates standby access (specifying in advance) and waits for receiving mode on this inserts." reserve link " pattern is a kind of operator scheme of simplification, is used to handle the signaling in the standby access.
Incoming call in the standby access will send to the inside modem of media gateway methodically.And the dialogue between the communication server rebulids, again call accepted.
Under standby mode, the media gateway periodic polling IP network of being saved.When the connection of IP network rebulids, media gateway will be switched back the normal service state to communication server signaling.When rebuilding conventional IP network signaling, all-calls all will keep can not interrupting.In addition, when the IP network is unavailable, can set up voice communication between website by community network.Inner dialing converts public number automatically to.When realizing the access control of distant-end node, also use this mechanism.
The administrative switching system present situation of mountain power supply administration in the administrative switching system basis in middle mountain power supply administration new dispatching communication building, take into full account the factor such as maturity, advance of various up-to-date exchange of speech technology, it is all very powerful to have built up an interconnection capability and systemic-function, realizes the administrative switching network that all types of user inserts.So this engineering is keeping on the reliable and stable basis of traditional programme-controlled exchange, adopting soft switch is that core technology makes up administrative switching network, promptly at new administration building configuration one cover soft switchcall server, realizes the CCF of whole network.The most of user in this building still realizes that by the user media gateway analog telephone inserts, and soft, the IP hard terminal of configuration of IP phone realizes that the VOIP user of this building and transformer station, power supply station inserts simultaneously.Aspect the network interconnection, by disposing each end office (EO) of a Tandem Gateway and middle mountain area, the PSTN network opening repeat circuit of administrative switching network of province company and operator, between mountain management unit of power supply administration in realizing and the inner constituent parts of middle mountain electrical network, with Southern Power Grid Company, Guangdong Power Grid company, between each power supply administration of Guangdong Power Grid intra-company, intercommunication between electric power inside, middle mountain and the public switched telephone network (PSTN), main business comprises Speech Communication, fax and fax etc., simultaneously, administrative switching network is as the backup means of electric power administrative switching network, for crucial effect is played in the safe operation of electrical production.
