Abstract: Technologies for optimizing frequency allocations in mobile communication systems can include a probabilistic model that can consider interference quality, coverage quality, frequency hop set length, service type, environment, and mobile radio speed. A frame erasure rate (FER) objective for call quality may be used as a key performance metric as FER performance can be closely related to voice quality. Mobile allocation list (MAL) length selection during the optimization can attempt to optimize the MAL length at the sector level. Choosing a MAL length per cell can provide an additional degree of freedom during the optimization process. The model can consider signal quality of neighbor cells in handover areas. The model can trade off co-channel and adjacent channel interference. Co-channel interference can be reduced at the expense of adjacent channel interference.
