Abstract

Method and apparatus delivering voice/data services within a piconet operating over a limited range or over a WLAN communicating with 3GPP devices by reformatting data into IP format before delivering to the WLAN. The service is short message service (SMS). Upon receipt of an SMS message, relevant routing information is retrieved. A PDGW address for the SMS message is identified and is sent to the PDGW address which identifies the WLAN user equipment (UE) for receiving the SMS and reformats the SMS message into IP format (text or encapsulation) for delivery to the UE. A protocol architecture is provided for SMS delivery over WLANs, in particular, for UMTS/CDMA based SMS over WLAN through two alternative mechanisms, i.e., SMS tunneling and SMS proxy, for protocols for the delivery of SMS across the WLAN. The invention enhances standard 802.11 in the context of UMTS and CDMA 2000; as well as other scenarios.
