The invention relates to implementation of multiple simultaneous calls for a mobile station in a mobile communication system. A common traffic channel (TCH) is allocated to several simultaneous calls (applications 1-n) of the mobile station (MS), so that the calls share the capacity of the common channel. Logical links are established for each call inside a common radio link protocol or link access control protocol, which is established over the common traffic channel between the mobile station (MS) and an interworking function (IWF). The common traffic channel (TCH) is allocated when the first call or calls are set up, and the capacity of the traffic channel is adjusted dynamically during the calls. The capacity of the common traffic channel is increased or the allocatd capacity is reallocated when a new call is added to the traffic channel. Correspondingly, the capacity is decreased or the allocated capacity is reallocated when a call is cleared from the common traffic channel. The common traffic channel is released after the last call has been cleared.
La présente invention concerne la mise en oeuvre d'appels simultanés multiples pour une station mobile dans une système de communication mobile. Un canal de trafic commun (TCH) est attribué à plusieurs appels simultanés (applications n-1) de la station mobile (MS) telle sorte que ces appels partagent la capacité du canal commun. Des liaisons logiques sont établies pour chaque appel à l'intérieur d'un protocole commun de liaison radio ou d'un protocole de commande d'accès à la liaison établi sur le canal de trafic commun entre la station mobile (MS) et une fonction d'interfonctionnement (IWF). Le canal de trafic commun (TCH) est attribué lorsque le premier ou les premiers appels sont mis en oeuvre, la capacité de ce canal étant réglée dynamiquement pendant les appels. La capacité dudit canal augmente, ou bien la capacité affectée est réaffectée lorsqu'un nouvel appel vient s'ajouter au canal. De même, la capacité est réduite ou bien la capacité affectée est réaffectée lorsqu'un appel est effacée du canal de trafic commun. Ce canal est libéré une fois le dernier appel effacé.
