发明名称 SIGNAL SYSTEM FOR MULTI-ACCESS
摘要 PURPOSE:To allow a mobile station to find out an access channel in a short time by allowing each radio base station to send the same access channel information simultaneously when the service area is overlapped. CONSTITUTION:The sending timing is set equally to access channel signals A1, A2 of a radio zone 2-1 by radio zones 2-1, 2-2, 2-3. Moreover, the access channel signal A3 of the radio zone 3-2 has the same sent timing in the radio zones 2-1, 2-2, 2-3, 2-4. Then access channel signals A1, A2, A3 are received simultaneously for the mobile station at a location where the service area of the zones 2-1, 2-2, 2-3, 2-4 are overlapped. Thus, the access channel of the mobile station is decided by having only to check the radio wave of the access channels A1, A2 and A3.
