Wireless communication channel management
First Claim
1. Apparatus for maintaining a record of radio signal strength for a plurality of channels in a wireless communication system, the apparatus having:
- measuring means for detecting the radio signal strength on each channel;
storage means for storing information relating to the detected signal strengths, wherein the information is stored in the storage means in the form of a value for each channel, each value being representative of the respective detected signal strength on a channel, and the storage means includes an array, with the values being stored in positions in the array such that each position in the array is assigned to a particular channel; and
processor means for identifying a first channel carrying a highest signal strength of said detected signal strengths, determining whether a signal having said highest signal strength is transmitted from a first fixed device that is accessible by setting up a synchronization bearer on said first channel, and selecting a second channel of said plurality of channels having a lowest signal strength of said detected signal strengths for communication with said first fixed device when said first fixed device is accessible.

Abstract
A method and apparatus for maintaining a record of radio signal strength for a plurality of channels in a wireless communication system is provided. A detector detects radio signal strength on each channel, and a memory stores information relating to the detected signal strengths. The information is stored in the form of a value for each channel. Each value is stored in an array and values are stored in the array such that each position in the array is assigned to a particular channel. The use of an array allows stored values to be associated with respective channels by the position that the value is held in.

8. A method of maintaining a record of radio signal strength for a plurality of channels in a wireless communication system, said method comprising the steps of:
-
detecting the radio signal strength on each channel;
storing information relating to the detected signal strengths, wherein the step of storing information is performed by storing a value for each channel that is representative of the detected signal strength on that channel, the values being stored in positions in an array such that each array position is assigned to a particular channel;
identifying a first channel carrying a highest signal strength of said detected signal strengths;
setting up a synchronization bearer on said first channel to determine whether a signal having said highest signal strength is transmitted from a fixed device which is accessible by a portable device; and
selecting a second channel of said plurality of channels having a lowest signal strength of said detected signal strengths for communication with said fixed device when said fixed device is accessible by said portable device. - View Dependent Claims (9)

10. A communication system comprising:
-
a plurality of fixed devices; and
a plurality of portable devices for communication with at least one of said plurality of fixed devices using at least one of a plurality of channels;
wherein at least a first portable device of said plurality of portable devices comprises;
a detector that measures signal strengths on said plurality of channels;
a memory that stores said signal strengths in positions of an array;
said positions being indicative of particular channels of said plurality of channels; and
a processor configured to scan said array to identify a first channel carrying a highest signal strength of said signal strengths, determine whether a signal having said highest signal strength is transmitted on said first channel from a first fixed device of said plurality of fixed devices that is accessible by said first portable device by setting up a synchronization bearer on said first channel, and select a second channel of said plurality of channels having a lowest signal strength of said signal strengths for communication with said first fixed device when said first fixed device is accessible by said first portable device. - View Dependent Claims (11, 12)
