Description
Technical field
The present invention relates to digital cluster communication technical field, more particularly to a kind of PDT clusters core network system and its disaster tolerance
Switching method.
Background technology
Two-node cluster hot backup is refered in particular to based on the hot standby of the two-server in high-availability system（Or High Availabitity）, because of two machine High Availabitities
At home using more, therefore two-node cluster hot backup of gaining the name, two-shipper High Availabitity is divided into by the switching mode in work：Main-standby mode
（Active-Standby modes）With double host modes（Active-Active modes）, main-standby mode is to refer to a service
Device is in the state of activation of certain business（That is Active states）, stand-by state of another server in the business（I.e.
Standby states), and double host modes are to refer to two kinds of different business activestandby state each other on two-server respectively（I.e.
Active-Standby and Standby-Active states.
At present, PDT group systems typically use two-node cluster hot backup disaster tolerance, to the execution equipment in PDT group systems（As exchanged
Machine, application server）The execution equipment of redundancy is disposed, hot standby each other two perform equipment due to needing to use identical IP,
Strange land can not be arranged on, it is impossible to realize long-distance disaster, and hot standby between the execution equipment of two pairings, disaster tolerance function does not have
Maximize.

Breath is sent to new execution network element node processing, and new execution network element is received after data, inquires about the pent meeting for performing network element
Service data is talked about, the session flow of pent execution network element is continued executing with, the data of new session flow are updated to simultaneously
In conversational services data, it is ensured that any network element that performs can take over other session services for performing network element in core net.I.e.
All execution network elements in core net are all hot standby each other, effective guarantee user service it is uninterrupted.
Preferably, the storage network element includes data-base cluster or distributed memory database.
Preferably, the execution network element includes switching centre or application server.
Preferably, node selection network element obtains each running status and service ability for performing network element, set up and tie up
Shield performs network element state table.Perform the foundation that network element state table is selected as network element node.
Preferably, it is excellent to perform network state, network element disposal ability, network element processing of the network element state table including performing network element
First level.
The disaster tolerance switching method of a kind of PDT clusters core network system of the present invention, for a kind of above-mentioned PDT clusters core
Net system, comprises the following steps：
Node selection network element monitoring each performs the running status of network element；
When some execution network element is stopped, node selects network element by the data performed in the network element session cycle being stopped
It is sent to the execution network element of another normal work；
The execution network element of the normal work is received after the data that node selection network element is sent, and inquiry stops work from storage network element
The conversational services data of the execution network element of work, continue executing with the session flow for the execution network element being stopped, new session flow
Data simultaneously be updated in conversational services data.
This method makes any network element that performs in core net to take over other session services for performing network element, i.e. core net
In all execution network elements it is all hot standby each other, effective guarantee user service it is uninterrupted.
Preferably, node selection network element obtains each running status and service ability for performing network element, set up and tie up
Shield performs network element state table.
The beneficial effects of the invention are as follows：Select network element as unified external communication interface using node, each performs net
The settable differences of the IP of member, so as to realize long-distance disaster, while all execution network elements in core net are all hot standby each other, have
Effect ensures the uninterrupted of user service.
