  • Method of allocating a new frequency plan in a communication system
    Patent number: 5490137
    Abstract: A new frequency plan is allocated in a communication system by first comparing (30) the channels in the old frequency plan with the channels in the new frequency plan to identify any problem channels that may exist (31). The system then attempts to clear any problem channels by reassigning (14) mobile stations, that may be currently assigned to those problem channels, to channels common to the old and new frequency plans, first non-problem channels. The new frequency plan is then implemented (15) by activating any new channels that are not active under the old frequency plan and deactivating any old channels that are not a part of the new frequency plan and are not currently assigned. Any remaining mobile stations still assigned to problem channels are then reassigned (17) within the new frequency plan and the problem channels are then de-allocated.
