Method and apparatus for delivering voice/data services within a piconet operating over a limited range or over a WLAN (1803) communicating with 3GPP devices by reformatting data into IP format before delivering to the WLAN (1803). The service is Short Message Service (SMS) (102). Upon receipt of the SMS message, relevant routing information is retrieved. A PDGW (1805) address for the SMS message is identified and sent to the PDGW address which identifies the WLAN use equipment (UE) (1801) for receiving the SMS and reformats the SMS message into IP format for delivery to the UE. A protocol architecture is provided for SMS delivery over WLANs, in particular, for UMTS/CDMA based SMS over WLAN (1803) through two alternative mechanisms: SMS tunneling and SMS proxy, for protocols for the delivery of SMS across the WLAN (1803).

L'invention porte sur un procédé et un appareil de fourniture de services vocaux/données via des picoréseaux sur des distances limitées, ou via un RLSF communiquant avec des dispositifs 3GPP en reformatant les données en format IP avant de les transmettre au RLSF. Le service est un service de messages courts (SMS). Lors de la réception d'un message SMS, on retrouves les informations pertinentes. L'adresse PDGW du message SMS une fois identifiée est transmise à l'adresse PDGW qui identifie l'équipement utilisateur (UE) du RLSF devant recevoir le SMS et reformate le message SMS en format IP (texte ou encapsulation) pour le transmettre à l'UE. L'architecture du protocole de transmission de SMS par RLSFs, à base SUTM/AMCR, utilise deux mécanismes de rechange, la tunnellisation de SMS et le mandataire de SMS, comme protocoles de transmission d'un SMS via un RLSF. L'invention perfectionne les 802.11 standards dans les contextes SUTM et AMCR 2000, ainsi que d'autres scénarios.
