摘要:
A positioning time interval control device for controlling a time interval for measuring a position includes an obtaining unit configured to obtain a movement state and a movement speed of a mobile terminal, and a positioning time interval setting unit configured to set the time interval for measuring the position of the mobile terminal and a time interval for outputting position information derived from the measurement based on the movement state and the movement speed of the mobile terminal obtained by the obtaining unit. The positioning time interval setting unit changes the time intervals when the movement state and/or the movement speed of the mobile terminal is changed. At the time interval set by the positioning time interval setting unit, the mobile terminal obtains the position information of the mobile terminal and outputs the position information.

A positioning apparatus for performing a positioning operation based on distance to an access point includes an access point detection unit configured to detect an access point, a memory unit configured to store the access point detected by the access point detection unit for each of channels, a channel setup unit configured to set a channel to be scanned based on the access points in the memory unit, and a positioning operation unit configured to perform positioning based on the distance to the access point detected by the access point detection unit. The access point detection unit detects the access point based on the channel set by the channel setup unit.
摘要:
A mobile terminal receives information adapted to the current location of the mobile terminal via a mobile communication network from an information service providing communication apparatus that sends information adapted to current locations of mobile terminals to mobile terminals. The mobile terminal, repeats identifying the location of the mobile terminal, and calculates a linear movement distance of the mobile terminal between a past location of the mobile terminal and the current location of the mobile terminal. The mobile terminal transmits a signal indicating the current location if the linear movement distance is greater than a threshold, but does not transmit the signal indicating the current location if the linear movement distance is less than the threshold.
