User Equipment Triggered Handover with Long Connected-Discontinuous-Reception Cycle in Connected Mode

摘要

While operating in connected discontinuous reception (C-DRX) mode, a wireless communication device may initiate handover operations when a neighboring base station is determined by the wireless communication device to be a better serving cell than a base station operating as the current serving cell for the wireless communication device. Instead of transmitting a measurement report to the current serving cell, the wireless communication device may select one of the neighboring base stations as the new serving cell, responsive to measurements of the current serving cell and the neighboring cells performed by the wireless communication device during the on-duration of the C-DRX cycle. This enables a longer C-DRX cycle, which leads to the wireless communication device saving more power during non-real-time sensitive background data transmissions, while also avoiding higher handover failure rates and extra Radio Resource Control signaling that may need to be performed as a result of radio link failure.

主权项

1. A wireless communication device comprising:
one or more antennas configured to transmit and receive wireless communication over a wireless network; and processing hardware configured to interoperate with the one or more antennas and cause the wireless communication device to:
measure a current serving base station and one or more neighbor base stations upon the wireless communication device entering an on-duration of a connected discontinuous (C-DRX) mode of operation;select a best neighbor base station from the one or more neighbor base stations as a new serving base station responsive to measuring the current serving base station and the one or more neighbor base stations; andtrigger a handover procedure to the new serving base station to have the new serving base station initiate a handover operation.
