Method and apparatus to facilitate influencing handover decisions
View Patent ↗A cellular communications system end-user transceiver ( 303 ) automatically determines ( 101 ) at least one received signal strength metric as corresponds to both a presently-utilized base station ( 307 ) and at least one presently un-utilized base station ( 309 ) to provide one or more corresponding received signal strength values. This transceiver then determines ( 102 ) whether to purposefully alter this received signal strength value(s). When deciding to make the alteration, the transceiver automatically alters ( 104 ) the received signal strength value(s) to provide one or more corresponding altered signal strength values. The transceiver then transmits ( 105 ) the latter in order to influence a handover decision in favor of handing over the transceiver from the presently-utilized base station to the presently un-utilized base station.
1. A method comprising:
at an end-user transceiver of a handover-based communications system:
automatically determining a received signal strength value for a presently-utilized base station, a received signal strength value for a presently un-utilized base station, and a difference between the received signal strength value for the presently un-utilized base station and the received signal strength value for the presently-utilized base station;
determining a handover threshold being applied by the presently-utilized base station;
determining whether to purposefully increase the received signal strength value for the presently un-utilized base station based on the difference between the received signal strength value for the presently un-utilized base station and the received signal strength value for the presently-utilized base station such that it is determined to purposefully increase the received signal strength value for the presently un-utilized base station when the received signal strength value for the presently-utilized based station is sufficiently weak and the difference between the received signal strength value for the presently un-utilized base station and the received signal strength value for the presently-utilized base station is less than the handover threshold being applied by the presently-utilized base station;
upon determining to purposefully increase the received signal strength value for the presently un-utilized base station, automatically increasing the received signal strength value for the presently un-utilized base station to provide an increased signal strength value for the presently un-utilized base station such that the increased signal strength value for the presently un-utilized base station exceeds the received signal strength value for the presently-utilized based station by at least the handover threshold being applied by the presently-utilized base station; and
transmitting the increased signal strength value for the presently un-utilized base station in order to influence a handover decision in favor of handing over the handover-based communications system end-user transceiver from the presently-utilized base station to the presently un-utilized base station.
