METHODS AND APPARATUS FOR ENABLING ROBUST FORWARD HANDOVER IN LONG TERM EVOLUTION (LTE) COMMUNICATION SYSTEMS

摘要

PROBLEM TO BE SOLVED: To provide methods and apparatus for enabling inter-cell connections, e.g., during a forward handover or radio link failure (RLF).;SOLUTION: A user terminal such as UE stores identity information associated with a source cell, and use this information in accessing a target or other cells subsequently to radio link failure so as to enable access to context information of the user terminal. A base station is configured to improve handover performance by associating context information with a newly assigned terminal identity. The handover performance may be enhanced by enabling connection processing in the event of inability to retrieve user terminal context from a source cell.;COPYRIGHT: (C)2014,JPO&INPIT
