Claim 0:
1. A method performed by a terminal, the method comprising:
receiving by the terminal from a base station a RRCRelease message, wherein the RRCRelease message includes a first information for a second resume procedure, and the first information for a second resume procedure includes a Signaling Radio Bearer2 (SRB2) indicator and a Data Radio Bearer (DRB) list;
determining by the terminal, based on the first information for a second resume procedure, a first radio bearer group;
receiving by the terminal from the base station a system information, wherein the system information includes a first timer value, a second timer value, a first threshold, and a second threshold, and wherein the first threshold is related to a reference signal received power and the second threshold is related to a data volume;
initiating by the terminal a resume procedure;
starting by the terminal a timer after applying a Medium Access control (MAC) cell group configuration and before resuming SRB1 of which configuration is restored from UE Inactive Access Stratum (AS) context; and
stopping by the terminal the timer in case that a RRCResume is received,
wherein MAC reset and cell selection procedure are performed when the timer expires,
wherein the first timer value is used if all conditions of a first condition group are fulfilled, and
wherein the first condition group includes the reference signal received power being greater than the first threshold and the data volume being smaller than the second threshold and a second resume procedure related information being included in the system information.
