Patent ID: 8892096

Claim:
A method, in a mobile station, for finding base stations in a radio communication network (N), the method comprising the steps of: scanning a set of frequencies assigned for transmission by base stations in active transmission intervals (TI) of a transmission cycle (TC), said set of frequencies being associated with a pre-determined discontinuous transmission scheme specifying a relationship between starting times of the active transmission intervals of the frequencies in the set, said scanning being performed during a scanning cycle (SC) corresponding to the transmission cycle (TC), and determining the frequencies at which the base stations transmit, wherein the start of each scanning is made at a point in time that is specified for the corresponding frequency by the discontinuous transmission scheme and the scanning of one frequency involves ending scanning of this frequency at the end of a time range (TR) of pre-determined length corresponding to the length of the active transmission interval (TI) if no signal is detected within this time range.
