Abstract
A method for monitoring with discontinuous BCCH carriers in GSM, in which a mobile station can monitor a neighboring base station in each frame, or one in each frame. i.e. once in 4.615 ms, even where the base stations do not transmit continuously on a beacon carrier. Control information is intermittently transmitted from one or more base stations to one or more mobile stations. Traffic information is transmitted between the base station and the mobile station. The base station using n (n less than 8) time slots of a TDMA frame. The base station is monitored by the mobile station within a predetermined time slot of the TDMA frame during which the base station transmits additional information that is neither control information nor traffic information. The monitoring by the mobile station during the predetermined time slot (TS) is synchronized with the monitoring of further provided mobile stations.
