Method of assigning a fixed subscriber unit (FSU) to communicate with a particular base station and a system including a plurality of wireless FSUs. The system includes a plurality of base stations, which are coupled to a telecommunications network. Each FSU is coupled to a subscriber communication device, and each FSU is configured to communicate wirelessly with at least a base station. The FSU measures signal strength of a set of base stations. The FSU sends a message with the measured signal strength of the set of base stations to a base station. Circuitry coupled to the base station determines at least a base station to which the FSU is to be assigned based on the message and additional information in the circuitry coupled to the base station. In response to the determining by the circuitry coupled to the base station, the base station sends to the FSU a message including the base station to which the FSU is to be assigned. |

DETAILED DESCRIPTION Embodiments of the invention are directed to a fixed subscriber unit, equipment coupled to a base station, and related methods in a telecommunications system using fixed subscriber units (FSUs).
A subscriber's equipment is able to communicate with the public switched telephone network (PSTN) by communicating through a FSU, which communicates wirelessly with equipment coupled to the PSTN.
An FSU is assigned to communicate wirelessly with a particular base station.
Embodiments of the invention are directed to more efficient assignment of an FSU to a base station from among a set of base stations and more efficient communication between an FSU and a base station.
For example, according to one embodiment of the invention, an FSU attempts to be assigned to the base station having the greatest signal strength from among various base stations coupled to the network.
Later, according to such an exemplary embodiment of the invention, equipment coupled to the base station causes the FSU to be reassigned to a different base station based on more efficient use of base station resources or other resources, or based on other considerations.
FIG.
1 illustrates a telecommunications system with a fixed subscriber unit, according to an embodiment of the invention.
FIG.
1 shows a single radio base station, radio BS 104, and single fixed subscriber unit (FSU) 107.
However, a typical system would contain multiple base stations and multiple fixed subscriber units.
An embodiment of the invention helps to assign each fixed subscriber to a base station from among the set of base stations.
Local exchange 101 is coupled to the public switched telephone network (PSTN) 100.
Local exchange 101 may be coupled to telephone equipment such as a wired telephone set 102 via wired link 110.
Local exchange 101 also allows for communication with subscriber equipment that is coupled into the system via a wireless link.
As shown, local exchange 101 is coupled to base station controller, BS Controller 103, via link 111
