Hybrid channel allocation in a cellular network
First Claim
1. A method for channel allocation in a mobile communication network, comprising:
- providing an estimate of respective traffic density in each of a plurality of cells in the network;
allocating to each of the plurality of the cells a first respective set of static channels for use in communicating with mobile units, the first respective set comprising a respective number of the channels that is chosen based on the estimate of the traffic density so that a probability for all the static channels in the first respective set to be in use simultaneously for communicating with the mobile units is no less than a predetermined threshold probability; and
allocating to each of the plurality of the cells, depending on the static channels allocated to the cells, a second respective set of dynamic channels.

Abstract
A method for channel allocation in a mobile communication network, based on an estimate of respective traffic density in each of a plurality of cells in the network, includes allocating to each of the plurality of the cells a first respective set of static channels for use in communicating with mobile units. The first respective set includes a respective number of the channels that is chosen based on the estimate of the traffic density so that a probability for all the static channels in the first respective set to be in use simultaneously for communicating with the mobile units is no less than a predetermined threshold probability. A second respective set of dynamic channels is allocated to each of the plurality of the cells, depending on the static channels allocated to the cells.

- 13. Apparatus for channel allocation in a mobile communication network that includes a plurality of cells, the apparatus comprising a computer, which is adapted to allocate to each of the cells a first respective set of static channels for use in communicating with mobile units, the first respective set comprising a respective number of the channels that is chosen, based on an estimate of respective traffic density in each of the cells, so that a probability for all the static channels in the first respective set to be in use simultaneously for communicating with the mobile units is no less than a predetermined threshold probability, the computer being further adapted to allocate to each of the plurality of the cells, depending on the static channels allocated to the cells, a second respective set of dynamic channels.
- 25. A computer software product for performing channel allocation in a mobile communication network that includes a plurality of cells, the product comprising a computer-readable medium in which program instructions are stored, which instructions, when read by a computer, cause the computer to allocate to each of the cells a first respective set of static channels for use in communicating with mobile units, the first respective set comprising a respective number of the channels that is chosen, based on an estimate of respective traffic density in each of the cells, so that a probability for all the static channels in the first respective set to be in use simultaneously for communicating with the mobile units is no less than a predetermined threshold probability, the instructions further causing the computer to allocate to each of the plurality of the cells, depending on the static channels allocated to the cells, a second respective set of dynamic channels.
