Title
(EN) IMPROVED SESSION SETUP IN AN ENERGY-EFFICIENT CELLULAR WIRELESS TELECOMMUNICATIONS SYSTEM
(FR) ÉTABLISSEMENT DE SESSION AMÉLIORÉ DANS UN SYSTÈME DE TÉLÉCOMMUNICATIONS CELLULAIRES SANS FIL ÉCONOME EN ÉNERGIE
Abstract
(EN)
The present invention provides a random access procedure for establishment of a data connection between a terminal and a SA-cell in an energy-efficient network, such as e.g. a BCG2 network, wherein the total session setup time is shortened. An information request message (IRM) transmission from the mobile terminal is used for selecting the SA-cell that will serve the mobile terminal (i.e. set-up a data session with this SA-cell) and is simultaneously used for performing a 'contention-free-like' random-access procedure towards all candidate SA-cells. In this way performing a RACHSA procedure after selecting a SA cell becomes unnecessary, the random access time is shortened and the uplink resources (at the selected SA-cell) and the uplink transmissions from the terminal are more effectively used.
(FR)
La présente invention concerne une procédure d'accès aléatoire utilisée pour établir une connexion de données entre un terminal et une cellule SA dans un réseau économe en énergie (un réseau BCG2, par exemple), dans laquelle le temps total d'établissement de session est raccourci. La transmission d'un message de demande d'informations (IRM) depuis le terminal mobile est utilisée pour sélectionner la cellule SA qui doit desservir le terminal mobile (établissement d'une session de données avec cette cellule SA, par ex.) et également pour exécuter une procédure d'accès aléatoire du type à résolution de conflits pour la totalité des candidates cellules SA. Une fois la cellule SA sélectionnée, il est donc inutile d'exécuter une procédure RACHSA, le temps d'accès aléatoire est raccourci et l'utilisation des ressources en liaison montante (à la cellule SA sélectionnée) et des transmissions en liaison montante, depuis le terminal, est plus efficace.
