Cell for self-configuring wireless communication network

摘要

A cell, preferably a stand-alone device, arranged for wireless communication with a plurality of other cells in a communication network, e.g. a TDMA network such as a DECT based network. The cell includes a processor performing a selection algorithm which selects a reference cell among other cells. The selection algorithm bases the selection on a wireless signal, e.g. an RF signal, received from at least two other cells. Further, the cell includes a wireless receiver for receiving a first wireless signal, e.g. an RF signal, from the reference cell with time synchronization information for the reference cell. The cell includes a wireless transmitter which transmits time synchronization information for the cell itself represented in a second wireless signal, e.g. and RF signal. The selection algorithm selects the reference cell based on transmission link quality measurements and cell path information received from a number of cell candidates. The cell preferably also itself transmits cell path information, e.g. at regular intervals. Preferably, the cell can generate a random number and transmit it in wireless form as its cell identity code. A network of such cells can be self-configured, i.e. no manual action is required. Further, it allows changes in network topology, e.g. change of position of one or more cells, since each cell can automatically adapt to a new topology and select the most reliable reference cell to synchronize to.

1. A cell unit for wireless communication with a plurality of other cell units, the cell unit comprising:
a processor configured to perform a selection algorithm configured to select a reference cell unit among the plurality of other cell units based on a wireless signal received from at least two of the other cell units, wherein the selection algorithm is configured to select the reference cell unit based on cell path information collected from the at least two of the other cell units, the cell path information for a cell unit including information regarding a path between a timing reference base station and said cell unit, and wherein the selection algorithm selects a combination of results of transmission link quality measurements performed on wireless links between the cell unit and the at least two other cell units and the collected cell path information, a wireless receiver configured to receive a first wireless signal from the reference cell unit with time synchronization information for the reference cell unit represented therein, the reference cell unit being one among the other cell units which the cell unit has selected as the one to synchronize to, and a wireless transmitter configured to transmit a second wireless signal with time synchronization information for the cell unit represented therein.
