WIRELESS MOBILE TERMINAL DEVICE
First Claim
1. A wireless mobile terminal device capable of using two or more wireless communication systems, comprising:
- a position data detector that detects position data representing a position of the wireless mobile terminal device;
a wireless communication system type data detector that detects wireless communication system type data representing a wireless communication system being used by the wireless mobile terminal device or relation data related to the wireless communication system type data;
a memory that accumulates the position data detected by the position data detector and the wireless communication system type data or the relation data detected by the wireless communication system type data detector in association with each other;
a memory controller that autonomously and sequentially stores the position data and the wireless communication system type data or the relation data into the memory; and
a wireless communication system type data retriever that selects, upon receipt of current position data representing a current position of the wireless mobile terminal device, wireless communication system type data of the current position of the wireless mobile terminal device or relation data related to the wireless communication system type data of the current position through adaptive retrieval of a plurality of pieces of the position data and a plurality of pieces of the wireless communication system type data or the relation data in association with each other, which are autonomously and sequentially stored by the memory controller and which are accumulated in the memory.
