IPC: H04B7/26
Filed: 1988-08-24
Abstract: PURPOSE:To reduce the trouble such as the collection of a traffic and the sensitivity reduction by comparing the receiving level of a position informing signal from a stored and registered fixed radio equipment and the receiving level of a position informing signal from other fixed radio equipment and changing a fixed radio equipment to be registered in a communication control unit based on the comparison result. CONSTITUTION:For example, a mobile radio equipment 3a counts the number of a position informing signals from other fixed radio equipment 42 received by a receiving level larger than a position informing signal from a position registered fixed radio equipment 41. When the counted value is larger than a prescribed value and the device is in a radio zone 51 of the position registered fixed radio equipment 41, other fixed radio equipment 42 is the shortest and the position registration is updated. For such a reason, the position registration is executed to the radio zone of the fixed radio equipment always at the shortest distance. Thus, the number of moving radio devices 3a-3e registered for a radio zone is not collected to the special one, the collection of the traffic is eased and the call loss can be reduced.

Title: Track transit signal detecting system in optical head access
Inventor: NAKAMURA HIROBUMI
IPC: G11B7/085
Filed: 1986-09-09
Abstract: PURPOSE:To detect and decide the number of track transits, to shorten an access time and to process at high speed by converting an analog signal detected by an optical detection part due to the track transits into a digital signal and counting the number of track transits.
