A method in a mobile communication system, comprising a mobile station and a base transceiver station, which are both arranged to use radio link protocol (RLP) and link protocol (L2R) in non-transparent data transmission. At least a first and a second frame of fixed lengths are defined for the radio link protocol for data transmission, the frames being of different lengths. The link protocol is arranged to transmit status information defining data transmission. In non-transparent data transmission between the mobile station and the base transceiver station, remapping during the data transmission between said frames is arranged to be initiated. The initiation of the remapping is arranged to be indicated to the link protocol layer (L2R). Current status information on the link protocol (L2R) is arranged to be transmitted in the radio link protocol (RLP) frame transmitted first after said remapping.

Cette invention concerne un procédé pour système de communication mobile comprenant une station mobile et une station émettrice-réceptrice de base, conçues toutes deux pour utiliser un protocole de liaison radio (RLP) et un protocole de liaison (L2R) pour la transmission non transparente de données. Pour la transmission de données, ont définit au moins une première et une seconde trame de longueurs fixes, mais différentes, pour le protocole de liaison radio. Le protocole de liaison est conçu pour transmettre des informations sur l'état qui définissent la transmission de données. Pour la transmission non transparente de données entre la station mobile et la station émettrice-réceptrice de base, un remappage intervient entre les trames pendant la transmission de données. On fait en sorte que le lancement du remappage soit indiqué à la couche de protocole de liaison (L2R). L'information sur l'état actuel du protocole de liaison (L2R) est communiquée dans la trame (RLP) de protocole de liaison radio transmise après ledit premier remappage.
