Abstract: Disclosed are a method, apparatus and device for managing a threshold pair change. The method comprises: determining a radio link monitor reference signal In Sync indication/Out Of Sync indication monitoring threshold; and when the radio link monitor reference signal In Sync indication/Out-Of Sync indication monitoring threshold changes, respectively managing, in conjunction with the state of a current radio link failure timer and according to the change of an In Sync indication/Out-Of Sync indication threshold pair, an In Sync indication counter, an Out-Of Sync indication counter, and a timer related to a radio link failure. By means of the present application, the channel quality under a new channel quality requirement can be more accurately reflected, so that a radio link failure state can be determined more accurately according to the current channel quality requirement.

Abstract: A bearer mapping method and a device thereof, a base station and a terminal are provided, so as to solve how to unify the mapping relationship between the bitmap of the MAC CE of the duplication activation/deactivation at the network side and that at the terminal side. The method includes: indicating a mapping relationship between a bearer ID and a bitmap in an MAC CE, where the MAC CE is a control element for a duplication activation indication or deactivation indication, and the bearer ID is an ID of a bearer configured with a duplication function.

Abstract: A notification method and device for the execution of PDCP data recovery, and same is used to notify an SN to execute a PDCP data recovery process. The notification method for the execution of packet data convergence protocol (PDCP) data recovery comprises: a primary base station sending an inter-node signaling message between the primary base station and a secondary base station to the secondary base station to notify the secondary base station of the execution of a PDCP data recovery process, and the inter-node signaling message is used to instruct the secondary base station to execute a PDCP data recovery process. The method for executing packet data convergence protocol (PDCP) data recovery comprises: the secondary base station receiving the inter-node signaling message sent by the primary base station.
