Title:
MOBILE GRASPING SYSTEM
Document Type and Number:
Japanese Patent JP2005295182
Kind Code:
A
Abstract:

To provide a mobile command system which can be grasped accurately for the position of a mobile to a target position.

A base station communication device 21 transmits a retransmission request signal 66 including information for changing response timing dt to a polling signal 64. Thus, the responding timing dt of the position signal 65 transmitted from each mobile station communication device 22 can be shifted. The collision of the position signal 65 can be prevented. Thus, a normal position signal 65 can be received, and the position of the mobile 61 can be grasped accurately. A command signal can be transmitted to the mobile of the desired positional relationship to the target position by grasping accurately the position of the mobile.
