Method of bringing a wireless telecommunication cell into DTX mode

摘要

In a method and system for automatically bringing a cell into DTX mode, a time period is introduced during which the outcome of bringing a cell into DTX mode is observed. The cell can return to a transmission mode if the outcome is non-satisfactory as determined by some criteria. Hereby an improved automated DTX method can be implemented which helps save energy in a cellular radio system.

主权项

1. An automated method of bringing a cell in a cellular radio network into DTX mode comprising:
determining coverage requirements of a geographical area covered by the cellular radio network, selecting a cell in the cellular radio network to bring into DTX mode, moving the cell into DTX mode, verifying during a non-zero time period an outcome of the moving of the cell into DTX mode, and determining if the cell is to remain in DTX mode or if the cell is to return to a transmission mode based on the outcome during the non-zero time period, wherein the cell is returned to the transmission mode when one of the following occurs:
if a predetermined number of active user equipments of the cell have not moved to another cell during the non-zero time period; orif a predetermined number of idle user equipments of the cell have not made a cell reselection during the non-zero time period; orif during the non-zero time period a neighboring cell of the cell experiences a load above a predetermined threshold.
