Title: A PROXY DEVICE IN A CELLULAR TELECOMMUNICATION SYSTEM
Abstract:
A cellular telecommunication system includes a radio access portion comprising a plurality of base stations (111) able to be offset by wireless link (303), as well as a core network portion comprising a device for controlling quality of service policies (124) connected via a first link (158) to a gateway (125) by which radio bearers are established. A proxy device (300) intercepts, on said first link (158), each session establishment message or session update message; and when the intercepted message does not concern a radio bearer involving a base station offset by wireless link, propagates the message to its recipient. Otherwise, the proxy device (300) determines a remaining bandwidth via said wireless link and, when the remaining bandwidth covers a bandwidth need expressed in the intercepted message, propagates the message to its recipient; and otherwise, modifies the message by indicating a bandwidth need that is less than or equal to the remaining bandwidth.
