Claim Text:
1. A method of wireless communication, comprising: determining when a remaining battery power of a user equipment (UE) is lower than a first threshold value and a second threshold value, the first threshold value differing from the second threshold value; receiving inter-radio access technology (IRAT) measurement instructions from a base station for measuring signals of neighboring base stations; comparing a serving cell signal strength with a third threshold value when the remaining battery power fails to meet the second threshold value; eliminating IRAT measurements when the remaining battery power is lower than the first threshold value; and extending a periodicity of the IRAT measurements when the remaining battery power is lower than the second threshold value and when the serving cell signal strength is larger than the third threshold value even when the IRAT measurement instructions support a shorter IRAT measurement period.
