Abstract
Utilizing a sequential local search optimization algorithm, a determination is made of the cell/transceiver retunes needed to implement, given a current frequency plan, a better frequency plan for a certain cellular communications system. Each of the individual cell/transceiver retunes is evaluated to determine if it meets certain save criteria, and if so, is saved as an intermediate frequency plan in a sequence of saved intermediate frequency plans necessary to migrate from the current frequency plan to the determined near-optimal frequency plan. A sequential implementation of these intermediate frequency plan revisions is then made to gradually reach, in a known and controlled manner, the better frequency plan.
Claims23
A method for determining a gradual frequency plan revision process, comprising the steps of:
- executing a sequential optimization algorithm to compute a best sequence of individual retunes needed to be made in order to implement, given a current frequency plan, a better frequency plan for a certain cellular communications system;
- manipulating the best sequence of individual retunes to determine an ordered plurality of plural retunes, each plural retune comprising several of the individual retunes and effectuating an intermediate frequency plan revision;
- and
- sequentially implementing these intermediate frequency plan revisions to gradually reach the better frequency plan.
A method for determining a gradual frequency plan revision process, comprising the steps of:
- executing a sequential optimization algorithm to iteratively compute a sequence of frequency assignment vectors for moving a cellular communications system from a current frequency plan to a better frequency plan;
- evaluating for each iteratively computed frequency assignment vector whether certain vector store criteria are met;
- if so, storing that iteratively computed frequency assignment vector as one intermediate frequency assignment vector within a sequence of a plurality of stored intermediate frequency assignment vectors;
- and
- sequentially implementing the stored sequence of intermediate frequency assignment vectors as a sequence of frequency plan retunes within the cellular communications system to gradually reach the better frequency plan.
