METHODS, APPARATUSES, RELATED COMPUTER PROGRAM PRODUCT AND DATA STRUCTURE FOR DECIDING ON A SIGNALING SCHEME FOR HANDOVER

摘要

A first method (and related first apparatus) includes transmitting, in a handover request message, an indication of a first protocol version; a second method (and related second apparatus) includes receiving, in the handover request message, the indication, deciding, based on the received indication and a second protocol version, on a value of an information element included in a handover request acknowledgement message to be transmitted, the information element indicating usage of a first or second signaling scheme, and transmitting the handover request acknowledgement message including the information element; and in the first method receiving the handover request acknowledgement message including the information element; and a third method (and related third apparatus) including receiving the handover command message including the information element, and configuring according to one of the first and second signaling schemes indicated by the information element.

主权项

1. A method for supporting a user equipment (UE) handover, comprising: operating a communication network, including operating a target base station (BS) that supports up to a first protocol release and operating a source BS that supports up to a second protocol release;
wherein operating the target BS and operating the source BS includes:
sending, from the source BS, a handover request message to the target BS, the handover request message indicating a third protocol release used by the source BS to configure the UE;receiving, at the target BS, the handover request message from the source BS;sending, from the target BS, a handover request acknowledge message to the source BS, wherein, on a condition that the third protocol release is newer than the first protocol release, the handover request acknowledge message indicates that the UE perform a full configuration;receiving, at the source BS, the handover request acknowledge message from the target BS; andsending, from the source BS, a handover command message to the UE, wherein, on a condition that the received handover request acknowledge message indicates that the UE perform a full configuration, the handover command message indicates that the UE perform a full configuration.
