Enhanced unlicensed mobile access network architecture

摘要

An Unlicensed Mobile Access (UMA) network architecture. In a specific embodiment, the network architecture includes a mobile station and an access point in communication with the mobile station. A UMA Controller (UNC) communicates with the access point. A Service GateWay (SGW) communicates with the UMA controller. The SGW includes functionality to route user-plane packets in the UMA. In a more specific embodiment, the functionality includes UNC user-plane functionality offloaded from the UNC to the SGW; Serving GPRS Support Node (SGSN) user-plane functionality; access-authentication functionality sufficient to enable the SGW to enable the SGW to bypass a legacy SGSN control plane; and/or Radio Network Controller (RNC) user-plane functionality sufficient to enable communications between the SGW and the RNC.

主权项

1. A system comprising:
an unlicensed mobile access (UMA) controller (UNC); a security gateway (SGW) in communication with the UNC, wherein the SGW includes functionality to route user-plane packets in the UMA, and wherein the functionality includes UNC user-plane functionality offloaded from the UNC to the SGW; a processor; and a machine-readable storage medium coupled to the processor, the machine-readable storage medium including:
one or more instructions for performing a gateway function between a client and the UMA controller;one or more instructions for performing a function associated with a servicing general packet radio services support node (SGSN); andone or more instructions for performing a function associated with the UMA controller; wherein the SGSN user-plane functionality is adapted to enable the SGW to route internet protocol (IP) services and associated data within the UMA without passing the IP services and associated data through a legacy SGSN module.
