Embodiment Construction

[0051] The core of the present invention is to aim at the shortcomings of the existing technical solutions, adopt a 1+1 backup mode for each service single board of the gateway device, set different logic board numbers for each service single board and its backup, and set different logic board numbers for different numbered The same virtual board number is set for the business single board and its backup, and a virtual logical correspondence table is established according to the set logical board number and virtual board number, and a group of logical board numbers and The service boards running in this group. In the data forwarding routing table, the virtual board number is used to identify the address of the service single board. When a message enters the gateway device, it first looks up the virtual board number storing the user context information through the routing table, then finds the logical board number for forwarding processing through the virtual logic corresponden...

Abstract

This invention discloses a transposition method for main prepared single board of gateway device, which comprises, creating 1+1 backup for every business single board and virtual logic relevance table for the said single board and backup; when needs, modifying the host-prepare relation in the said table to complete the transposition. The invention can prevent the business data missing when transposing device, decreases effect to data transmission, and improves reliability and stability.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for realizing the switchover of active and standby single boards of gateway equipment. Background technique [0002] The third generation mobile communication system (3G), with its advanced air interface technology, comprehensive IP packet switching and control technology of the core network, has made the technology of the data communication industry and the wireless communication industry have been well integrated, making wireless communication more efficient. Satisfy the rapidly growing demand for data services (mainly IP services) well. [0003] WCDMA (Wideband Code Division Multiple Access) / CDMA2000 are third-generation mobile communication systems, which adopt a structure similar to that of the second-generation mobile communication system. From the perspective of system structure and functions, both include radio access network (RAN) and core network...
