Patent ID: 8615276

Claim:
A terminal apparatus, comprising: a communication unit which performs wireless communications compatible with a plurality of wireless communication schemes, respectively; an inspection unit which inspects a remaining amount of battery to be supplied to said communication unit; and a control unit which controls a standby operation that said communication unit is to perform on the plurality of wireless communication schemes, based on the remaining amount of battery inspected by said inspection unit, wherein said communication unit performs standby operations in the plurality of wireless communication schemes in parallel, said control unit defines degrees of priority for the plurality of wireless communication schemes, respectively, said control unit causes said communication unit to inspect whether, in a first state where the remaining amount of battery is large, a wireless communication is feasible or not in the wireless communication scheme having a low degree of priority, and when the wireless communication is not feasible, said control unit sets long the time interval of the standby operation in the wireless communication scheme having a low degree of priority, said control unit causes said communication unit to inspect whether, in a second state where the remaining amount of battery is smaller than the first state, the wireless communication is feasible or not in the wireless communication scheme having a low degree of priority, and when the wireless communication is not feasible, said control unit stops the standby operation in the wireless communication scheme having a low degree of priority, and in a third state where the remaining amount of battery is smaller than the second state, said control unit stops the standby operation in the wireless communication scheme having a low degree of priority, regardless of whether the wireless communication is feasible or not in the wireless communication scheme having a low degree of priority, and a time interval in the standby operation in the wireless communication scheme having a high degree of priority is adjusted according to whether the wireless communication is feasible or not in the wireless communication scheme having a high degree of priority.
