LINK FAILURE RECOVERY METHOD AND APPARATUS

摘要

Embodiments of the present invention disclose a link failure recovery method and apparatus. The method includes: first receiving, by a primary base station, failure report information sent by a user equipment, acquiring, according to the failure report information, an identifier of a DRB that needs to be reconfigured, and reconfiguring a parameter for the DRB that needs to be reconfigured; and then sending, by the primary base station, a first reconfiguration message to the user equipment, so that the user equipment reconfigures a failed DRB according to the first reconfiguration message. The present invention is applicable to the field of communications systems.

主权项

1. A link failure recovery method, comprising:
receiving, by a primary base station, failure report information sent by a user equipment, wherein the failure report information is an identifier of a failed secondary serving cell or an identifier of a failed data radio bearer (DRB), wherein the failed secondary serving cell is controlled by a secondary base station, and the failed DRB is carried on a radio link between the failed secondary serving cell and the user equipment; acquiring, by the primary base station according to the failure report information, an identifier of a DRB that needs to be reconfigured, and reconfiguring a parameter for the DRB that needs to be reconfigured; and sending, by the primary base station, a first reconfiguration message to the user equipment, wherein the first reconfiguration message comprises the identifier of the DRB that needs to be reconfigured and the parameter reconfigured for the DRB that needs to be reconfigured.
