CA 2318480

The invention relates to a method for reconfiguring a cellular radio network connection (170) comprising a network part (128) having a connection (170) to a mobile station (150) through at least one radio bearer. According to the invention, a first party of the connection (170), i.e. the network part (128) or the mobile station (150), sends a second party of the connection (170), i.e. the mobile station (150) or the network part (128), a reconfiguration request message (BEARER_RECONF_REQ) concerning at least one radio bearer. The second party of the connection (170) possibly replies to this by sending the first party of the connection (170) a reply message (BEARER_COMPL/BEARER_FAIL) to the radio bearer reconfiguration request message (BEARER_RECONF_REQ). The radio bearer reconfiguration request message (BEARER_RECONF_REQ) comprises at least one radio bearer identifier (BID) and, for example, bearer quality of service (BEARER QOS) of the radio bearer in question. The possible reply message (BEARER_COMPL/BEARER_FAIL) comprises at least one radio bearer identifier (BID) and possibly also bearer quality of service (BEARER QOS) assigned to the radio bearer in question, or a cause (CAUSE) for a failed reconfiguration of the radio bearer in question.

L'invention concerne un procédé de reconfiguration d'une connexion (170) de réseau radiocellulaire comportant un élément réseau (128) en connexion (170) avec une station mobile (150) via au moins une porteuse radio. Selon l'invention, un premier interlocuteur de la connexion (170), à savoir l'élément réseau (128) ou la station mobile (150), envoie à un second interlocuteur de la connexion (170), à savoir la station mobile (150) ou l'élément réseau (128), un message de demande de reconfiguration (BEARER_RECONF_REQ) concernant au moins une porteuse radio. Le second interlocuteur de la connexion (170) répond éventuellement à ce message en envoyant au premier interlocuteur de la connexion (170) un message de réponse (BEARER_COMPL/BEARER_FAIL) au message de demande de reconfiguration (BEARER_RECONF_REQ) de la porteuse radio. Ce message de demande de reconfiguration (BEARER_RECONF_REQ) de la porteuse radio comporte au moins un identificateur de la porteuse radio (BID) et, par exemple, une qualité de service (BEARER QOS) de la porteuse radio en question. L'éventuel message de réponse (BEARER_COMPL/BEARER_FAIL) comporte au moins un identificateur de la porteuse radio (BID) et, éventuellement, aussi une qualité de service de la porteuse (BEARER QOS) attribuée à la porteuse radio en question, ou une cause (CAUSE) de l'échec d'une reconfiguration de la porteuse radio en question.
