Problems solved by technology

[0005] Under the solution of CU separation, although the previous BRAS still has two previous backups, such a backup can no longer realize the hot backup function. Since the processing of protocol messages has been moved up to the CP, the UP is only used as a simple forwarding device. , the user's information table and routing are sent from the CP to the UP, so there is no complete dual-system hot backup method under the CU separation scheme.

Abstract

The invention discloses a dual-machine hot backup method based on CU separation, comprising: the control plane CP receives the priority parameter sent by the user plane UP, wherein the UP includes a first UP and a second UP, and the priority parameter Including the priority parameter of the first UP and the priority parameter of the second UP; the CP determines the main UP and the backup according to the priority parameter of the first UP and the priority parameter of the second UP UP; the CP sends an active / standby status identifier to the UP, and the active / standby status identifier is used to indicate whether the UP is the active UP or the standby UP; the CP sends the user online report according to the UP Generate a user information table and a user routing table; the CP sends the user information table and the user routing table to the UP. The embodiment of the invention also provides a device. Adopting the embodiment of the present invention can realize a complete dual-system hot backup method under the condition of CU separation.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and equipment for dual-system hot backup based on CU separation. Background technique [0002] During broadband access, the Broadband Remote Access Server (BRAS) will pass the authentication request through the Remote Authentication Dial in User Server (Radius) protocol according to the user name and password carried in the user request message. Radius authentication, after the authentication is successful, the BRAS will assign an IP address to the user. In the actual deployment process, the active and standby BRASs will be deployed, and the synchronization of user information and routes between the active and standby BRASs will be realized. Reliable access is realized through the deployment mode of active and standby. [0003] In the actual application process, in order to improve the reliability of user access, reliable access is achieved by deploying hot backup. Ho...
