In case of RRC-Idle,EMM-Idle, will UE and EPC keeps bearer configuration?

+4 votes

Suppose UE is attached with LTE n/w and have one default bearer and one dedicated bearer. eNodeB is releasing RRC connection due to inactivity. Now in RRC-Idle/EMM-Idle, will UE and EPC keeps bearer configuration of both dedicated and default bearer? Or will it have only default bearer configuration.

Answer is YES. In RRC-IDLE (when there is no radio connection between UE and eNodeB) and ECM-IDLE (when there is no UE associated S1-AP signalling) states, UE's NAS and MME's NAS retains bearer context. SGW and PGW both the nodes will also retain bearer context.

All bearers will be released when the ue enters RRC-IDLE, When the UE needs to establish a bearer again or the network pages the UE due to incoming data , The UE has to re establish RRC connection.
