International Classification:

H04W 4/00

US Classification:

370329

Abstract:

In one embodiment, a first access request is received from a mobile device. The access request may be received through a first access medium for a virtual access point name (APN). A session is created with a service using a first real access point name (APN) for the mobile device. A second access request is received through a second type of access medium. The request may be received through a second virtual APN. A session is determined that is active for the mobile device through the first access medium and the second access request is assigned the first real APN even though the request is received through a second access medium. The continuity of the connection may then be maintained because the first real APN is still being used. In this case, a handoff of the connection from the first access network to the second access network is performed while the connection to the service is maintained through the first real APN.

International Classification:

H04Q 7/00

US Classification:

370328

Abstract:

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.

H04L 12/713

Abstract:

A networking system may include a first network such as a private cloud network and a second network such as a public cloud network. The first network may include a switch coupled to a computing resource. To facilitate a robust and flexible inter-network connection, the networking system may include network connector circuitry having a connector endpoint at the first network and a network connector coupling the connector endpoint to a network element at the second network. A controller for the first network may provide control signals and configuration data to the network connector circuitry to form the connection to the second network and may configure the switch to forward external network traffic to and from the connector endpoint via a switch port directly coupled to the connector endpoint.
