Abstract

See full text

The invention concerns a mobile station and a method of controlling cell idle-mode re-selection measurements in a mobile station in a mobile communication system comprising base stations where a base station defines a cell, and a mobile station for communicating with at least one base station, in which method when the mobile station is in idle mode, the mobile station monitors paging messages coming from the base station informing the mobile station of possible transmissions to come, the paging messages arrive at certain intervals, the interval defining a discontinous reception period (DRX period), and further in idle mode the mobile station (MS) performs cell re-selection measurements on certain channels. The number of cell re-selection measurements (Proposal) is proportional to the length of the DRX period, whereby during a longer DRX period a higher number of cell re-selection measurements is performed than during a shorter DRX period.
