Problems solved by technology

[0004] It can be seen from the above description that although the networking mode of the MSC pool can realize disaster recovery and has a certain disaster recovery capability, this method of realizing disaster recovery will have a certain impact on the surrounding network elements
For example, the BSC needs to select an MSC after receiving a service request message, which will increase the complexity of service processing on the BSC

Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0033] It can be seen from the description of the background technology that the existing methods for implementing disaster recovery are likely to affect the surrounding network elements, which will increase the processing complexity of the surrounding network elements. In order to overcome the problems in the prior art, the embodiment of the present invention provides a node capable of realizing self-disaster recovery. The node adopts a unified interface to connect with surrounding network elements, and only appears as one network element to surrounding network elements, and can Realize disaster recovery while reducing the impact on surrounding network elements.

[0034] see figure 2 As shown, the self-disaster recovery node provided by the embodimen...

Abstract

The invention provides a disaster recovery method which includes steps: after the service distribution unit receives service request message, the service distribution unit selects a normal service process unit from at least two service process units, and sends the received ervice request message to the selected service process unit for processing; wherein, the service distribution unit distributes message by the unit of user. In addition, the invention also provides a node device, which includes the service distribution unit distributing message by the unit of user and at least two service process units; wherein, the service distribution unit is used for selecting a normal service process unit from the at least two service process units after receiving service request message, and sending the received service request message to the selected service process unit; and the service process unit processes the received service request message. Without affecting surrounding networks, the method of the invention can realize the disaster recovery.

Description

technical field [0001] The invention relates to network communication technology, in particular to a method and device for realizing disaster recovery. Background technique [0002] In a traditional mobile communication network architecture, a mobile switching center (MSC, Mobile SwitchCenter) can be connected to multiple base station controllers (BSC, Base Station Control), but a BSC can only be connected to one MSC. This networking mode is relatively simple. For the service request message initiated by the user, the BSC can directly route it to the MSC connected to itself after receiving the service request message. However, the disaster recovery capability of this networking method is poor. For example, if an MSC fails and goes down, all BSCs connected to the MSC will lose their function, and all users within the coverage of these BSCs will be unable to for business correspondence. [0003] In order to solve the above problems, 3GPP R5 introduced the MSC pool (Pool) net...
