Abstract:
1. A communication apparatus which communicates with a plurality of networks, said apparatus comprising: a setting unit that adjusts and sets, in accordance with a communication condition of each of the plurality of networks, a communication hold period in which the communication apparatus does not communicate with any one of the plurality of networks; a notification unit that notifies each of the plurality of networks of the communication hold period set by said setting unit; and a stop unit that stops communication with the plurality of networks on the basis of the setting of the communication hold period, wherein said setting unit sets the communication hold period of each network so as to overlap portions of the communication hold periods of the plurality of networks without any overlap of communication participation times of the plurality of networks, and wherein, during the communication hold period in which the communication apparatus does not communicate with any one of the plurality of networks, the communication apparatus enters a power saving mode, and wherein the communication hold period is defined in accordance with a communication hold period start time for defining a timing to start the communication hold period, a communication hold period cycle for defining a period of the communication hold period, and a communication hold period length for defining a length of the communication hold period, and said setting unit sets the communication hold period of each network so as to set the communication hold period length shorter than the communication hold period cycle, set the networks excluding at most one network in the communication hold period at any timing of the communication hold period cycle, and set a period in which the communication hold periods of all the networks are overlapped longer than a predetermined period.
