Abstract:
1. A method for managing radio resources in a mobile communication network, said resources being allocated to a plurality of communication channels each associated with a set of requested quality of service parameters, said method comprising the use of a resource preemption procedure following the acceptance of a new request for a communication channel associated with a set of requested quality of service parameters and following the detection of a lack of resources necessary to support said new request, the resource preemption procedure being designed to modulate allocation of resources to previously active communication channels as a function of a priority level associated with each of them, so as to set up an order relation between the different communication channels, wherein said preemption procedure comprises the following steps: a) identifying active communication channels on the network that might be preempted and among them, selecting the lowest priority communication channel according to predefined selection criteria; b) evaluating the gain in radio resources obtained by at least partial reconfiguration of the selected communication channel, said selected communication channel and said associated gain being memorized in a reconfiguration list; c) checking if the gain achieved by all communication channels included in the list is sufficient to support said new request; and d) repeating steps a to c:
