Abstract: Network operators are striving to find ways to provide stable video services amid a rapid increase in video data traffic. In order to provide stable video services with constrained network resources, network operators attempted to reduce video file sizes and to cache videos for future use. However, network operators failed to exploit user information and to leverage benefits of distributing these functionalities across the network. This disclosure provides systems and methods for efficiently delivering video and managing video caches by exploiting user information and by distributing video delivery functionalities across the network.

Abstract: Network operators are striving to find ways to provide stable video services amid a rapid increase in video traffic. In order to provide stable video services with constrained network resources, network operators attempted to reduce video file sizes using a content adaptation engine (CAE). However, network operators failed to efficiently readdress video flows to CAEs. This disclosure provides systems and methods for efficiently readdressing video flows to CAEs.

Abstract: Systems and methods are disclosed for receiving a request at a packet gateway to allocate a new bearer for a mobile device on a wireless telecommunications network; identifying, at the packet gateway, existing bearers that have a quality of service (QoS) that can be reduced without dropping the existing bearers; reducing, at the packet gateway, the QoS of the existing bearers; reclaiming resources at the packet gateway that were previously in use by the existing bearers; and allocating the new bearer for the mobile device using the reclaimed resources at the packet gateway without causing any of the existing bearers to be disconnected, wherein the existing bearers have a lower priority than the new bearer, and wherein the existing bearers have previously been designated as capable of being preempted.

Abstract: An example method includes receiving a packet for a flow associated with a subscriber; determining if a home agent element has a context for the flow by communicating a handover query to a network element; assigning an Internet protocol (IP) address for the subscriber in response to the home agent element not having the context for the flow; and creating a session for the subscriber, where the session is created using inter-process communication between the home agent element and the network element.

Abstract: A method includes a network originating a QoS reservation message and communicating the network-originated QoS message through a radio access network (RAN) from an access gateway (AGW) to an access terminal (AT). The network-originated reservation message does not cause any network resource reservation by itself, but causes the AT to initiate a network resource reservation according to one or more parameters in the network-originated QoS reservation message. Accordingly, an existing network infrastructure supporting AT-originated QoS reservation may support network-originated QoS reservation (or proxied QoS) without any updates to an access-network infrastructure, such as the RAN. The method includes, in response to the network-initiated QoS reservation message, communicating a reservation confirmation through the RAN from the AT to the AGW. The reservation confirmation whether that the QoS reservation was successful.

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.

Abstract: In one embodiment, a load balancer receives a message from a tunnel termination gateway (TTG) associated with a mobile device. The load balancer may receive messages from a plurality of TTGs. A gateway node in a plurality of gateway nodes in which to send the message is determined. The load balancer then assigns a NSAPI for use by the gateway node. For example, the NSAPI may be associated with a tunnel that is generated between the TTG and GGSN. The load balancer ensures that the assigned NSAPI is not currently in use at the gateway node. Thus, no overlapping of NSAPIs may occur even though the load balancer is processing messages from multiple TTGs for multiple gateway nodes.
