Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a method for the reestablishment of RRC connection of an emergency call in an LTE network. ;SOLUTION: A mobile device initiates an RRC connection reestablishment procedure for an emergency call through a failure situation in an LTE network environment. The mobile device establishes RRC connection with an acceptable cell to transmit an emergency call. When the mobile device detects the failure situation such as a radio link failure, the RRC connection is disconnected consequently. The mobile device searches for available cells to reestablish the RRC connection, and can search for only the acceptable cells. The mobile device may initiate an RRC connection reestablishment procedure with an acceptable cell. The mobile device also attempts to reestablish the RRC connection with a cell which belongs to the same PLMN as the original acceptable cell. The mobile device may also enter an RRC_IDLE mode when detecting the failure situation. ;COPYRIGHT: (C)2011,JPO&INPIT
