The infoXTM-MDSP can provide an operable, manageable and open data service management platform for mobile operators, and the mobile operators can develop various rich and diverse mobile data services through the infoXTM-MDSP.
The info XTM-MDSP mainly comprises an access module and a processing node, is in a core position in the development of data services, has an open operation service platform (comprising a service management platform, a service enabling platform and a service publishing management center), and mainly completes the unified management, unified authentication and unified charging of the data services, and the service interaction of short message service, multimedia message service, WAP service, download service, streaming media service and the like is completed through the MDSP. Therefore, if the MDSP has a service interruption, it will cause the interruption of the data service of the whole network, and thus, the MDSP is required to have a high reliability.
In the prior art, a method for improving reliability of communication systems such as MDSP and the like includes: a redundant design technique is employed. The redundancy design technology is also called redundancy design technology, and is characterized in that one set or more than one set of functional channels, working elements or components which complete the same function are added at the core part of the communication system so as to ensure that the communication system can still work normally when the core part fails, thereby reducing the failure probability of the communication system and improving the reliability of the communication system.
In a communication system in a telecommunication service network, the reliability and the cost of the system are comprehensively considered, and the redundancy design technology which is most widely applied mainly adopts a dual-machine scheme, namely, a set of components with the same function is added.
In the dual-machine scheme, a 1+1 cluster is adopted for key equipment of a medium-and-small-capacity system, that is, 1 main unit and 1 redundant unit are configured. When one main unit fails, the service is switched to the redundant unit; when the failed main unit is repaired, the service can be used as a redundant unit, and the service can be switched to the main unit.
Based on the above method, a schematic diagram of a dual-device scheme for providing reliability of a communication system is shown in fig. 1, and a processing procedure of the dual-device scheme is as follows:
all service processing units (including main service processing unit and redundant service processing unit) report their state information to the switching control unit at regular time, and the switching control unit backups the common information of all service processing units. And when the switching control unit finds that the state of the main service processing unit is abnormal according to the received state information, the switching control unit initiates a command of switching to the redundant service processing unit. Thus, the access part connects the system service from the main service processing unit to the redundant service processing unit, thereby ensuring the system to continue to operate reliably.
The above-mentioned method for improving reliability of communication systems such as MDSP in the prior art has the following disadvantages: when an unrecoverable fault occurs in a single machine (including a main service processing unit or a redundant service processing unit) and the double-machine switching fails; or, an unrecoverable failure occurs in both the two devices, which may cause the whole communication system to be broken down and all data services of the whole communication system to be interrupted.
