Abstract:
The present disclosure relates to a method for reestablishing an RRC connection in an LTE system and an electronic device thereof, and the method by which a base station reestablishes an RRC connection comprises the steps of: receiving an RRC connection reestablishment request message from an electronic device; confirming whether a context of the electronic device is present in the base station; if the context of the electronic device is not present, receiving a context of the electronic device from a base station which was in the process of an RRC connection with the electronic device; and reestablishing the RRC connection on the basis of the received context.
Abstract:
An apparatus implements a method for maintaining a voice call in a communication system providing a multi-Radio Access Bearer (RAB). In the method for maintaining a voice call in an electronic device, a data call and a voice call with a wireless network are connected. When an error of the data call is detected, the connection of the data call with the wireless network is released.
Abstract:
A method of a base station (BS) of a carrier aggregation (CA) is provided. The method includes determining whether a mobile station (MS) concurrently uses a first cell associated with a first carrier frequency and a second cell associated with a second carrier frequency, and controlling a handover of the MS using a measurement configuration set corresponding to a result of the determination among a plurality of measurement configuration sets that are set for each of handover related events.
