Problems solved by technology

[0004] During the research and practice of the prior art, the inventor found the following problems in the prior art: the current rolling upgrade process needs to wait for the isolated All the original calls on the board must be released before the new version can be loaded, but how long the original calls will last is an uncertain issue. Some calls may last for a long time, resulting in the entire upgrade taking a long time to complete , making the upgrade process uncontrollable
[0006] During the research and practice of the prior art, the inventor found that the second prior art has the following problems: due to the possible Reset, therefore, may cause some calls to be dropped, causing business interruption

Abstract

The invention discloses a business link switch method and a system belonging to the communication technology field. The method of the invention comprises: applying business treatment resource of a second business treatment unit; transmitting an establishment link message to the second business treatment unit, wherein the message carries the address information of a first business node and a second business node; receiving the establishment link message by the second business treatment unit, establishing a link between the first business node and the second business node according to the address information; switching the link to the second business treatment unit when the first business node and the second business node receive a switching link indication information. The business link switch method has advantages that when an unit rollingly upgrades in the same resource pool, the efficiency of rolling upgrade is improved and the service interruption maybe caused by the rolling upgrade is avoided.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and system for service link switching. Background technique [0002] With the rapid development of telecommunication technology, many telecommunication systems need to continuously upgrade the telecommunication system or telecommunication equipment in order to expand functions and add new services, and telecommunication equipment may find problems during operation. When solving problems, it is necessary to Equipment is upgraded and replaced. However, telecommunication equipment has relatively high reliability requirements. General telecommunication equipment requires 99.999% reliability, that is, only about 5 minutes of interruption time is allowed each year. How to reduce the service interruption time when equipment is upgraded or fails has always been an important issue for telecommunication equipment. Something that manufacturers and operators are very ...
