Abstract: A cellular telecommunication system comprises a radio access part comprising a plurality of base stations that can be offset by wireless connection, as well as a core network part comprising quality-of-service policy control equipment connected via a first connection to a gateway via which radio bearers are set up. Proxy equipment: intercepts, on said first connection, each session establishment or session update message; when the intercepted message does not concern a radio bearer involving a base station offset by wireless connection, propagates the message to its destination. Otherwise the proxy equipment: determines a remaining bandwidth via said wireless connection; when the remaining bandwidth covers a bandwidth requirement expressed in the intercepted message, propagates the message to its destination; and otherwise modifies the message by indicating a bandwidth requirement of no more than the remaining bandwidth.
