INFORMATION-PROVIDING DEVICE AND INFORMATION-PROVIDING METHOD, WIRELESS COMMUNICATION DEVICE AND WIRELESS COMMUNICATION METHOD, COMPUTER PROGRAM, AND WIRELESS COMMUNICATION SYSTEM

摘要

To reduce power consumption for communication operation wherein a client terminal at the time of offline searches a base station or access point. A server uses a communication information predicting algorithm to predict a location or time whereby the server becomes an offline state over a movement route of a client terminal, and a location or time whereby the server returns to an online state, and informs to the client terminal. The client terminal suspends a communication function when reaching the informed offline predicted location or time. The client terminal at the time of offline determines that the current location or time has reached an online return predicted location or time using location recognition or point-in-time recognition, and restores the communication function.
