Process for pre-emption of resources from a mobile communications network, with a view to establishing a service according to a maximum associated pre-emption rate

摘要

A mobile communications network comprises a core network (CN) connected to a radio access network (UTRAN). This network is constructed in such a way as to associate to each RAB, with a view to its establishment, a maximum rate for the pre-emption of resources from the network. Accordingly, when its radio access network (UTRAN) receives an RAB assignment request (associated to a requested rate and a maximum pre-emption rate) but there are insufficient resources available to allow the establishment of this RAB at the requested rate, it pre-empts resources from the network, which have previously been allocated to at least one other RAB, in order to perform the establishment of the RAB at a rate less than or equal to the maximum pre-emption rate associated to it.
