Claim:
A method of intercell handover of a call between a mobile station and a fixed network of an FDMA and/or TDMA cellular radiocommunication system, for handing over the call from the base station of a current cell to the base station of a neighboring cell, the method comprising the following steps: a) determination, by the mobile station, of a first indication relative to the quality of the radio link between the mobile station and the base station of the current cell; b) scan, by the mobile station of the broadcast control channel of at least one neighboring cell and corresponding determination of a second indication relative to the quality of the radio link between the mobile station and the base station of said neighboring cell; c) transmission to the fixed network, by the mobile station, of the first and second indications; d) a first comparison, by the fixed network, of the first and second indications in order to deduce therefrom, where necessary, at least one neighboring cell that is eligible for the intercell handover; e) allocation, by the fixed network, for the call in the eligible cell, of a traffic channel, at least in the uplink direction, set up at the same frequency and/or the same time slot as a traffic channel in the uplink direction which is allocated to the call in the current cell; f) determination, by the fixed network, of a third indication relative to the quality of the radio link between the mobile station and the base station of the current cell; g) determination, by the fixed network, of a fourth indication relative to the quality of the radio link between the mobile station and the base station of the eligible cell; h) a second comparison, by the fixed network, of the third and fourth indications in order to deduce therefrom, where necessary, an order of intercell handover.
