Cellular network resource control method and apparatus
First Claim
1. A method of providing mobile user terminals with access to a cellular radio access network, the method comprising:
- defining logical cells each comprising a set of sub-areas, each sub-area containing a radio transceiver for communicating with user terminals, and the sub-areas of a logical cell sharing one or more sets of downlink common control channels; and
for each logical cell, dynamically allocating one or more sub-areas to each user terminal within that logical cell, the sub-areas allocated to each user terminal transmitting and/or receiving the same dedicated information to/from the user terminal.

Abstract
A cellular radio access network comprising a plurality of radio transceivers geographically spaced so that neighbouring transceivers provide overlapping radio coverage for mobile user terminals, and a radio transceiver controller geographically spaced from and coupled to said plurality of radio transceivers, the controller being arranged to control each radio transceiver so that neighbouring transceivers can be configured to communicate with user terminals using either the same or different radio channels, whereby the effective cell sizes of the radio access network can be dynamically increased or decreased depending upon the demands placed on the available radio resources.
