Methods in a base station for handling handover, base station, computer program and computer program product

摘要

The invention relates to a method (50) in a base station (21) for handling handover of a user equipment (31) from the base station (21) to one of two or more target base stations (23, 25). The method (50) comprises the steps of: detecting (51) a physical cell identity confusion situation; initiating (52) handover preparations towards the two or more target base stations (23, 25) including conveying an information element to the two or more target base stations (23, 25); receiving (53) response messages from the two or more target base stations (23, 25), the response messages being based on the transmitted information element and thus being identical; transmitting (54) to the user equipment (31) a unique handover message, enabling the user equipment (31) to perform a handover to appropriate target base station (25). The invention also relates to base stations, computer programs and computer program products.

1. A method in a base station for handling handover of a user equipment from the base station to one of two or more target base stations, the method comprising the steps of:
detecting a physical cell identity confusion situation, initiating handover preparations towards the two or more target base stations including conveying an information element to the two or more target base stations, receiving response messages from the two or more target base stations, the response messages being based on the transmitted information element and comprising identical radio resource control connection reconfiguration messages, and thus being identical, transmitting to the user equipment a unique handover message, enabling the user equipment to perform a handover to appropriate target base station.
