Problems solved by technology

[0061] The main disadvantage of the prior art lies in the fact that although great efforts have been made to optimize the allocation of radio resources according to the previously presented techniques to optimize the allocation of radio resources through the compression of the TRAU frames for speech and the exchange of signaling streams, due to They are still very expensive to implement satellite-type radio links that are generally too large
[0062] Broadband satellite systems such as DVB-RCS, in fact, have the disadvantage that they are basically designed for the transmission of Internet data and are therefore not well developed for specialized applications such as speech with real-time constraints. good optimization

Embodiment Construction

[0175] 1. General principles

[0176] The invention itself is based on a method which is a completely new and inventive method of optimizing the allocation of radio resources. Its general principle is based on the analysis (and extensions and improvements thereof) of the signaling channel of the GSM signal, from which analysis the radio channel to be allocated is determined.

[0177] Note, however, that this differs significantly from prior art techniques where radio resources are systematically allocated once the radio transmission system detects the need for data transmission via satellite.

[0178] Referring to Figure 4, in a preferred embodiment, the general configuration implementing the present invention comprises three main entities:

[0179] - cellular network 42 of GSM type;

[0180] - Radio link 40 with dynamic allocation of dynamic and shared resources of DAMA type;

[0181] - An Internet network 41 operating according to the Internet IP protocol.

Abstract

The invention concerns a method for optimizing allocation of transmission resources in a mobile radio communication cellular network, the cellular network comprising at least one base station, BTS (421), controlled by a base station controller, BSC (422), and a connecting network connecting the BTS's with the BSC. The method consists in setting up, maintaining and terminating a communication channel between mobile terminals located in the cellular network, the setting up, maintenance and termination of the data communication channel using exchanges of signalling messages, the connecting network including at least one radio link (401) with shared resources between the base station(s) (412) and the base station controller (422). According to the invention, such a method includes the following phases: a first phase of analyzing the content of all or part of the signalling messages, the analyzing phase including a step of searching for and detecting in the content of the signalling messages data indicating a traffic activity; a second phase of allocating or not allocating a resource channel in said radio link (401) based on the data indicating a traffic activity.

Description

technical field [0001] The field of the invention is that of communication networks. Precisely, the invention relates to cellular networks such as in particular, but not exclusively, GSM ("Global System for Mobile Communications") or UMTS ("Universal Mobile Telecommunications Service"), in which communication with e.g. satellite-type radio transmission is implemented infrastructure links. [0002] The invention is particularly, but not exclusively, applicable to radio systems which allow a set of base stations (called "BTS" in the case of GSM and Node B in the case of UMTS) to be connected via satellite to This is made possible by the linking of a central device called a hub that distributes the data needed for transmission between the base stations and their base station controllers (BSC in GSM and RNC in the case of UMTS). Radio resources via satellite. [0003] In general, the invention can be applied in any cellular network comprising radio links with shared resources t...
