摘要
The present invention relates to a method and apparatus for controlling network access points in a wireless communicating system, said system comprising: one or more mobile stations, and one or more access points, each access point being arranged for operating in active mode or in inactive mode; said method comprising the steps of: transmitting, by a mobile station, a sensing signal indicating network and/or mobile station specific information associated with at least one mobile station of said system; receiving, by at least one access point or at least one control unit, said sensing signal; and controlling, by said access point or said control unit, transition from active mode to inactive mode, and vice versa, of one or more access points of said system based on said sensing signal.
說明書
This application is a continuation of International Application No. PCT/EP2013/057200, filed on Apr. 5, 2013, which is hereby incorporated by reference in its entirety.
The present invention relates to a method for controlling network access points in a wireless communicating system. Furthermore, the invention also relates to a method in a mobile station, a method in an access point or in a control unit, a mobile station device, an access point device or a control unit, a computer program, and a computer program product thereof.
A base station (eNodeB) in a 3GPP Long Term Evolution (LTE) system periodically transmits synchronization signals and relevant system information. A mobile station (user equipment, UE) shall carry out two essential steps to access the network:
A cell search procedure consisting of a series of synchronization steps upon which the UE acquires time and frequency synchronization and other crucial system parameters that are necessary to demodulate the downlink signals and channels; and
A random access procedure to declare its presence within the cell, obtain the correct uplink timing synchronization and a unique UE identity (C-RNTI).
The cell-search procedure is used in two cases: for initial synchronization, when a UE detects a cell for the first time and decodes the information needed to register to it; and for identifying new cells, upon a UE registered in the network and searches other cells for handover.
