Techniques for scheduling measurements for cells in multiple (e.g., GSM
and W-CDMA) wireless communication systems are described. GSM neighbor
cells are categorized based on a number of states. The states are
prioritized in a manner to achieve good performance. The GSM neighbor
cells are thus assigned different priorities depending on their states.
W-CDMA neighbor cells are prioritized relative to the states for GSM
cells. All W-CDMA neighbor cells can be assigned the same state, given
the same priority, and considered as "one" W-CDMA cell in the scheduling.
A cell in the GSM or W-CDMA system is selected based on the priorities of
the neighbor cells, and the selected cell is scheduled for measurement in
the next available frame. The highest-ranking GSM or W-CDMA cell for each
idle frame is thus granted use of that idle frame for measurement.
