1. A method of scheduling received signal measurements in a user equipment (UE) in a communication system, the received signal including broadcast information and being organized in successive frames, comprising the steps of:

  • evaluating a received signal strength indicator (RSSI) at only time instants outside of a broadcast information reception time, wherein during the broadcast information reception time the UE receives unacknowledged multimedia information, and the evaluating step is performed by the UE based on whether the UE is receiving unacknowledged multimedia information, independent of control by the communication system during a period in which the UE is unknown to the communication system, and during the period during which the UE is receiving unacknowledged multimedia information from the communication system;

    based on the evaluated RSSI, carrying out a cell re-selection procedure;

    changing a reception frequency to a frequency of a new cell, including checking a list of neighbor cells for the new cell and searching for a physical channel in the new cell at only time instants outside of the broadcast information reception time based on whether the UE is receiving unacknowledged multimedia information;

    if the physical channel in the new cell is found, reading a broadcast channel of the new cell and including the new cell in the list of neighbor cells; and

    if the physical channel is not found at only time instants outside the broadcast information reception time, interrupting the receiving of unacknowledged multimedia information and searching for the physical channel in the new cell at further time instants not only outside of the broadcast information reception time.
