Problems solved by technology

[0005] However, resetting all the physical termination points of the media gateway will cause the interruption of the existing services carried on the media gateway, and the smooth switching of services cannot be realized, thereby reducing user satisfaction

Embodiment Construction

[0042] see figure 1 , figure 1 It is a schematic diagram of networking of a dual-homing system according to an embodiment of the present invention. In a dual-homing system, two softswitches are set, namely, a master-home softswitch and a slave-home softswitch. Between the two softswitches Status maintenance and negotiation can be performed, as well as non-real-time data backup or data backup through maintenance commands.

[0043] The two softswitches are similar entities and provide the same functions; otherwise, they will not support the dual-homing function due to inconsistent functions. Each softswitch covers and controls a certain area, such as: metropolitan area 1 and metro area 2. In this embodiment, the primary home softswitch is the primary home softswitch of metropolitan area 1, and the secondary home softswitch of metropolitan area 2; similarly, the secondary home softswitch is the primary home softswitch of metropolitan area 2 , which is the slave softswitch of m...

Abstract

The method sets up two soft exchange devices for managing different network ranges as soft exchange devices with dual homes. Then, the method builds master-slave attribution relation between soft exchange devices with dual homes and media gateway. The method includes following steps: (1) when two soft exchange devices are needed to carry out exchange, slave home soft exchange device takes over all media gateway of master home soft exchange device; (2) slave home soft exchange device controls media gateway of master home soft exchange device to reset physical end points, which are in idle condition. Realizing dual homes, the method increases smoothing rearrangement of service in switching system so as to solve resources hung up.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for maintaining services during dual-homing switching. Background technique [0002] As users have higher and higher requirements for network security and reliability and network processing capabilities, operators must introduce sufficient capacity and various diversity means into the network when designing networks, so as to provide users with sufficient It is possible to reduce the impact of failures, improve the network's priority recovery capability, dual access capability, and multiple routing capabilities. But on the other hand, if the core control or processing equipment adopts the main and backup mode, it will not only increase the cost of network construction and maintenance and management, but also cause greater waste of resources due to the idleness of the backup equipment. [0003] Therefore, under the comprehensive consideration of several factors such ...
