Method and apparatus for selecting carriers

An apparatus for selecting carriers to be measured by a subscriber unit served by a cellular communication system and having a number of receivers operable to measure carriers in a frequency band, the method comprising the steps of:

• Means for dynamically determining a frequency of measurements updates when measuring carriers in the frequency band;
• wherein the frequency of measurements updates is indicative of the amount of time required by the subscriber unit to measure the carriers and wherein the amount of time required to measure the carriers is dependent on how many receivers a subscriber unit have;
• and
• Means for dynamically selecting a subset of carriers in the frequency band to be measured by the subscriber unit based on the frequency of measurement updates which is dependent on the frequency of measurement updates, which in turn is based on the number of receivers in a subscriber unit.
