Optimizing radio communication efficiency and methods thereof
First Claim
1. In a selective call radio operating in a communication system comprising a plurality of communication zones, a method of minimizing handovers between the selective call radio and the plurality of communication zones, comprising the steps of:
- measuring a temperature of the selective call radio receiving radiated signals from a first one of the plurality of communication zones;
measuring in the selective call radio an in-service signal power based on the radiated signals;
determining a modified signal power from the in-service signal power and an in-service signal power correction factor corresponding to the temperature; and
performing a handover by the selective call radio from the first one of the plurality of communication zones to a second one of the plurality of communication zones if the modified signal power and a handover threshold satisfy a predetermined condition.

Abstract
A selective call radio (106) operating in a communication system (100) including a plurality of radio base stations (104) operating in a corresponding plurality of communication zones (102), wherein the selective call radio is programmed to measure (206) a temperature of the selective call radio receiving radiated signals from a first one of the plurality of communication zones, measure (204) in the selective call radio an in-service signal power based on the radiated signals, determine (208) a modified signal power and an in-service signal power correction factor corresponding to the temperature, and perform a handover (212) from the first communication zone to a second one of the plurality of communication zones if the modified signal power and a handover threshold satisfy a predetermined condition.

17. A radio base station among a plurality of radio base stations of a communication system operating in a corresponding plurality of communication zones coupled to a selective call radio, wherein the radio base station comprises:
-
a transceiver; and
a processor coupled to the transceiver, wherein the processor is programmed to;
measure a temperature of the radio base station receiving radiated signals from the selective call radio in a communication zone of the radio base station;
measure an in-service signal power based on the radiated signals;
determine a modified signal power from the in-service signal power and an in-service signal power correction factor corresponding to the temperature; and
instruct the selective call radio to handover communication from the communication zone of the radio base station to a second communication zone of a corresponding second base station if the modified signal power and a handover threshold satisfy a predetermined condition. - View Dependent Claims (18, 19)
