Title:
AUTOMATIC ZONE SWITCHING METHOD FOR MOBILE STATION
Document Type and Number:
Japanese Patent JP3441278
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To attain the automatic switching between the zones of different user codes and also to quickly acquire even the carrier of an adjacent zone.
SOLUTION: In a digital multichannel access system, one of combination information 1-4 on desired user codes to undergo the automatic zone switching between different user codes is designated, and a subscriber number including plural designated user codes is extracted out of the subscriber number identification information 1-2 including all subscriber numbers. Thus the subscriber number identification information 1-7 on zone switching units are listed. Then the automatic zone switching is carried out between the different user codes, and the control carriers of adjacent zones are extracted based on the receiving input voltage obtained based on the carrier research result and arranged in the order of higher voltage levels in the preferred carrier information 1-9. This information undergoes the carrier research in a fixed frequency, so that the zone switchable carrier can be quickly acquired.
