<p>A mobile device initiates an RRC connection reestablishment procedure for an emergency call after experiencing a failure condition in an LTE network environment. The mobile device establishes an RRC connection with an acceptable cell to originate an emergency call. The mobile device detects a failure condition, such as a radio link failure, which disrupts the RRC connection. The mobile device searches for available cells that it may reestablish the RRC connection with, but can only find acceptable cells. The mobile device may initiate an RRC connection reestablishment procedure with an acceptable cell. The mobile device may also only attempt to reestablish the RRC connection with a cell that is part of a PLMN that the original acceptable cell was also a part of. The mobile device may also enter an RRC_IDLE mode upon detecting a failure condition.</p> |
