Method for improving the handing over a connection from one sgsn to another sgsn

Procede permettant d'ameliorer le transfert d'une communication d'un premier sgsn a un autre sgsn

Abstract

The present invention relates to a method for improving the handing over of a connection from one SGSN (I) to another, i.e. when an MS (Mobile Station) moves from one SGSN service area to another, and for the purpose of not interrupting the packet transmission and possible layer 3 procedures, and for optimizing the network utilization without adding complexity to SGSN, it is according to the invention suggested that at inter SGSN routing update, the old SGSN (I) is given the role as a temporary anchor whereas the other (new) SGSN (II) is temporarily working as a serving SGSN.
L'invention concerne un procédé permettant d'améliorer le transfert d'une communication d'un premier SGSN (I) à un autre SGSN, notamment lorsqu'une station mobile (MS) passe d'une zone de service SGSN à une autre zone de service. Afin d'éviter l'interruption du paquet envoyé et des éventuelles procédures couche 3 et d'optimiser l'utilisation du réseau sans pour autant rendre le SGSN plus complexe, l'ancien SGSN (I) reçoit, lors de l'actualisation d'acheminement inter nodal, la fonction de point d'ancrage temporaire, tandis que l'autre (le nouveau) SGSN( II) fonctionne temporairement comme SGSN de desserte.
