Preemption Method for Management of Radio Resources in a Mobile Communication Network

摘要

The invention relates to management of radio resources allocated to communication channels each associated with requested QoS parameters in a mobile communication network, consisting of the following if there is a lack of resources when accepting a new channel request:a—identify (30, 35) channels that might be preempted and among them, select (40) the lowest priority channel using an associated priority level;b—evaluate (50, 55) the gain in resources obtained by at least partially reconfiguring it, said channel and said gain being memorised;c—check (70) if the gain achieved by memorised channels is sufficient to support said new request, d—repeat steps a to c: until the gain obtained is sufficient, in which case memorised channels are reconfigured and the new request is accepted (80), oruntil all channels that could be preempted have been evaluated without obtaining sufficient gain, in which case the new request is refused (90).
