Abstract
The present invention relates to a system and method for wireless telecommunication in a packet-based network comprising a Software Radio Port (SRP) which functions as a radio base station and a VoIP gateway to interconnect the wireless network with the VoIP packet network. Together with a Network Server Platform (NSP) and VoIP call-server, the SRP combines mobile call processing signaling with the VoIP call signaling to establish calls between the mobile and VoIP device or between mobiles. The SRP establishes the voice path to the mobile station over the air and the RTP media path to a party over a packet network for a call. These two paths are interconnected at the SRP so that an end-to-end voice path is established.

12. A method of providing a path between a Voice over IP (VoIP) device in a network and a mobile station, comprising:
-
tuning the mobile station to a digital traffic channel (DTC) to establish a voice path wirelessly via a Software Radio Port (SRP); engaging a VoIP call-server to set up a VoIP call; generating a ringback tone to the mobile station; establishing a Real-Time Transport Protocol (RTP) media path for exchange of RTP data packets via said Software Radio Port (SRP); and interconnecting the voice path and the RTP media path over a packet network via said Software Radio Port (SRP). - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A method of providing a path between a Voice over IP (VoIP) device in a packet network and a mobile station, comprising:
-
processing a call connection request at a VoIP call-server; initiating mobile call set-up at a Network Server Platform (NSP); tuning the mobile station to a digital traffic channel (DTC) to establish a first path wirelessly via a Software Radio Port (SRP); establishing a Real-Time Transport Protocol (RTP) media path for exchange of RTP data packets via the SRP; and interconnecting the first path and the RTP media path over the packet network via the SRP.
