Description

Device and method for improving reliability of communication system and communication system

technical field

The invention relates to the communication field, in particular to a device and method for improving the reliability of the communication system and the communication system.

Background technique

infoXTM-MDSP (Mobile Data Service Piatform, Mobile Data Service Management Platform) is a platform system that realizes comprehensive management and unified access of data services on the mobile communication network. infoXTM-MDSP can provide mobile operators with an operable, manageable and open data service management platform. Mobile operators can carry out various mobile data services through infoXTM-MDSP.

infoXTM-MDSP is mainly composed of access modules and processing nodes. It plays a core role in the development of data services. It has an open operation business platform (including business management platform, business enabling platform, and business release management center), which mainly completes the data business. Unified management, unified authentication, unified authentication, unified billing, SMS service, MMS service, WAP service, download service, streaming media service and other business interactions must complete authentication, authentication, and billing functions through MDSP. Therefore, if the service of the MDSP is interrupted, the data service of the entire network will be interrupted. Therefore, the MDSP is required to have high reliability.

A method for improving the reliability of communication systems such as MDSP in the prior art is to adopt redundant design technology. Redundancy design technology, also known as redundancy design technology, is to add one or more sets of functional channels, working components or parts to the core part of the communication system to complete the same function, so as to ensure that when the core part fails, the communication system still remains It can work normally, thereby reducing the failure probability of the communication system and improving the reliability of the communication system.

In the communication system of the telecommunication business network, considering the system reliability and cost, the most widely used redundant design technology is mainly to adopt the dual-machine solution, that is, to add a set of components with the same function.

In the dual-machine solution, a 1+1 cluster is used for the key equipment of the small and medium-capacity system, that is, one active unit and one redundant unit are configured. When an active unit fails, the service is switched to the redundant unit; when the failed active unit is repaired, it can be used as a redundant unit, or the service can be switched to the active unit again.

Based on the above method, a schematic diagram of the principle of a two-machine solution that provides reliability of the communication system is shown in Figure 1. The processing process of the two-machine solution is as follows:

All business processing units (including the main business processing unit and the redundant business processing unit) regularly report their state information to the switching control unit, and the switching control unit backs up the common information of all business processing units. When the switching control unit finds that the state of the active service processing unit is abnormal according to the received state information, it initiates an instruction to switch to the redundant service processing unit. Therefore, the access part connects the system services from the main service processing unit to the redundant service processing unit, so as to ensure the continuous reliable operation of the system.

The shortcoming of the method for improving the reliability of communication systems such as MDSP in the above-mentioned prior art is: when running into stand-alone (comprising main service processing unit or redundant service processing unit) unrecoverable failure occurs, and two-machine switching fails; Or, if an unrecoverable failure occurs on both machines, the entire communication system will be paralyzed, and all data services of the entire communication system will be interrupted.

Step 61, the terminal user initiates a service request for browsing WAP pictures to the WAP gateway.

Step 62, the WAP gateway preprocesses the received service request, such as checking whether the WAP picture requested by the user terminal exists, and after confirming that the WAP picture exists, initiates an authentication and deduction request to the service access module of the MDSP.

Step 63, the service access module of the MDSP checks whether each service processing node of the system is abnormal, and sends an alarm to the network management system when it finds that the main service processing unit of the system fails and fails to switch to the redundant service processing unit.

Step 64, the service access module of the MDSP forwards the received authentication and fee deduction request to the emergency processing device.

Step 65, the log recording module of the emergency processing device records the detailed information of all authentication and fee deduction requests received, such as user ID, picture ID and other information, and outputs the recorded information to a designated directory for storage.

Step 66, the service processing module of the emergency processing device processes all the authentication and fee deduction requests received, and returns the pass response to the service access module of the MDSP for the authentication and fee deduction requests, and the service access module of the MDSP will receive the received The reply is passed to the WAP gateway.

Step 67: After receiving the above-mentioned response, the WAP gateway provides services to the user terminal normally, and the user terminal normally performs the service of browsing WAP pictures.

Step 68: After collecting the alarm information, the system administrator locates and restores the system fault.

Step 69: When the system returns to normal, the recovery processing module of the emergency processing device provides the system administrator with the log information recorded by the log recording module stored in the specified directory, and performs corresponding post-processing according to the processing instructions input by the system administrator. For example, supplementary deductions are made to users, and the actual fee is deducted at 0.20 yuan per user, so as to ensure the normal fee collection of operators.

The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed in the present invention can easily think of changes or Replacement should be covered within the protection scope of the present invention.
