Method, system and devices for improving discontinous reception in wireless communication networks

摘要

A method, system and devices for optimizing the discontinuous reception by a mobile terminal of signals transmitted from its serving base extension so battery and other user equipment resources can be saved by using an extended DRX period several orders of magnitude longer with respect to what is achievable in the current standard, without the terminal losing synchronization.

1. A method for discontinuous reception by a mobile terminal of wireless signals transmitted from its serving base station in a wireless communications network, said method comprising the following steps:
a) the mobile terminal sending to its serving base station an estimation of the maximum time it can remain without synchronizing its local clock to the signal's frame of said base station and still being time aligned with said frame with a timing error less than a certain threshold, where said threshold is a design parameter; b) the mobile terminal receiving from said base station an extended discontinuous reception period, where said period is calculated based on said maximum time estimation received from the mobile terminal; and c) the mobile terminal switching off certain of its sections during the extended discontinuous reception period, keeping operative its local clock and timing functions that allow said terminal to remain time aligned with the signal's frame of said base station.
