Description
Technical field
The present invention relates to the next generation network communication field, specifically, relate to a kind of method and device of in the next generation network system, realizing the media server disaster tolerance.
Background technology
, mainly comprise in 3G network at next generation network: soft switch is a kernel call control member in the next generation network, be used to finish CCF, professional trigger mechanism is provided simultaneously, can initiates service request to application server according to professional trigger policy; Application server is the core component of intelligent network, storaging user data and service logic, and according to service logic triggering operation flow, in the Business Processing process, control media server as required media resource is provided, thereby realize various business function; Media server, in next generation network, unification provides the media resource processing capacity, accepts the control of application server, and its medium connect by IP bearer network and gateway or IP terminal interaction, have embodied the networking thought that control separates with carrying.Wherein, media server all is very important core network element, undertake the critical function that media resource is provided for miscellaneous service, characteristics by communication network itself and media server self have determined media server to need extreme high reliability, as a high support that importance is exactly the disaster tolerance ability of reliability, whether can provide and improve disaster tolerance function efficiently, directly have influence on the application of media server, business is carried out and the stability of telecommunication intelligent network.
In most of media server framework that current telecommunications adopts, what adopt all is to concentrate the mode of disposing, kernel control module and resource module all concentrate on the unified service platform, what such deployment directly brought is the risk of Single Point of Faliure, though also can realize the disaster tolerance function of part by redundancy techniques such as two-shippers, but, fundamentally can't solve the single failure risk that geography/environmental hazard brings because physical location is single.
In addition, for the part of media server of implementing distributed deployment, can support the disaster-tolerant backup function in order to make it, then must realize redundant configuration by the mode of 1+1 or n+m, can carry out disaster tolerance when taking place and handle with the guarantee disaster, but the problem that this mode has but brought equipment increase, cost investment to strengthen.Simultaneously, owing in the deployment of this pattern, have many cover media servers, so also increased the cost that administers and maintains, inconvenience very greatly.
Therefore, on the basis of existing technology, people need a kind of method of the media server disaster tolerance that can solve the problem in the above-mentioned correlation technique and the scheme of device.
Summary of the invention
The object of the present invention is to provide a kind of disaster recovery method and device of simple and effective media server, can ensure the high reliability of media server.It fundamentally can't solve the single failure risk that geography/environmental hazard brings, and need not redundant configuration simultaneously, has significantly reduced the cost that administers and maintains.
According to an aspect of the present invention, a kind of media server disaster recovery method is provided, media server comprises a plurality of media control server modules and a plurality of Media Resource Server module, it is characterized in that, method may further comprise the steps: step S102 is provided with the disaster tolerance configuration data on media server; Step S104 when a generation in sensing a plurality of media control server modules is unusual, according to the disaster tolerance configuration data, selects a media control server module as new media control server module from a plurality of Media Resource Server modules; And step S106, other Media Resource Server module in a plurality of Media Resource Server modules is re-registered new media control server module, media server is resumed work.
According to an aspect of the present invention, step S104 realizes by following steps: step S1042, use the unusual of heartbeat signal sensing media control server module, and, from a plurality of Media Resource Server modules, select all normal Media Resource Server module of work and network condition according to the disaster tolerance configuration data; And step S1044, stop the medium resource service of selected Media Resource Server module, start its media control function, as new media control server module.
In addition, step S106 is further comprising the steps of: step S1062, application server connects with media server again, recovers service operation.
Heartbeat signal according to one aspect of the invention is the control protocol or the privately owned control protocol of standard.The control protocol of this standard comprises SIP, H.248 and MGCP
According to the media server disaster recovery method of one aspect of the invention,, have only so when two-shipper all to occur just starting Disaster Tolerant Scheme when unusual if the media control server module has been disposed the backup policy of two-shipper mode.
Another aspect of the present invention provides a kind of media server disaster tolerance device, media server comprises a plurality of media control server modules and a plurality of Media Resource Server module, it is characterized in that device comprises: the disaster tolerance configuration module is used for being provided with the disaster tolerance configuration data on media server; Sensing is selected module, be used for when a generation that senses a plurality of media control server modules is unusual, according to the disaster tolerance configuration data, from a plurality of Media Resource Server modules, select a media control server module as new media control server module; And re-register module, and being used for other Media Resource Server module of a plurality of Media Resource Server modules is re-registered new media control server module, media server is resumed work.
In above-mentioned media server disaster tolerance device, media server adopts distributed deployment.
According to another aspect of the present invention, sensing selects module also to comprise: unusual sensing module is used to use the unusual of heartbeat signal sensing media control server module; And the startup module, be used for after the medium resource service that stops selected Media Resource Server module, starting its media control function.In addition, re-register module and also comprise: connect and set up module, be used to make application server to connect with media server again, recover service operation.
