Methods, systems and devices for network congestion control exploit the inherent burstiness of network traffic, using a wave-based characterization of network traffic and corresponding multiplexing methods and approaches.

A digital data communications network that supports efficient, scalable routing of data and use of network resources by combining a recursive division of the network into hierarchical sub-networks with repeating parameterized general purpose link communication protocols and an addressing methodology that reflects the physical structure of the underlying network hardware. The sub-division of the network enhances security by reducing the amount of the network visible to an attack and by insulating the network hardware itself from attack. The fixed bandwidth range at each sub-network level allows quality of service to be assured and controlled. The routing of data is aided by a topological addressing scheme that allows data packets to be forwarded towards their destination based on only local knowledge of the network structure, with automatic support for mobility and multicasting. The repeating structures in the network greatly simplify network management and reduce the effort to engineer new network capabilities.

A method, system and computer readable medium for providing support for CUPS PFCP Session at UE Level for Serving Gateway are presented. In one embodiment, a method includes providing a Packet Forwarding Control Protocol (PFCP) session at a User Equipment (UE) level for a Serving Gateway (SGW); anchoring, by the SGW, the UE session; handling, by the SGW, buffering of Idle UE and UE Active-to-Idle transitions; using, by the SGW, a same PFCP session for all Packet Data Networks (PDNs); and using, by the SGW, a same Buffering Action Rule (BAR) for all PDNs.

This application discloses example application instance address translation methods. One example method includes receiving, by a control plane device from a mobile edge cloud control device, an address of a target application instance of an application service accessed by a terminal. The control plane device can then send the address of the target application instance to a first user plane device. The control plane device can then instruct the first user plane device to set, as the address of the target application instance, a destination address of an uplink packet that is of the terminal and is associated with the application service.

A method for advertising a route, applied to a layer 3 network in an open systems interconnection OSI model. The network includes a control plane network element and a user plane network element that are connected to each other, and the method includes: receiving, by the user plane network element, a packet whose source IP address is a first IP address; determining, by the user plane network element, that the first IP address is not authenticated; sending, by the user plane network element, an authentication request that includes the first IP address to the control plane network element; receiving, by the user plane network element, a first session from the control plane network element; and advertising, by the user plane network element, first routing information based on the first session, where a destination address of the first routing information is the first IP address.

Cloud delivered access may be provided. A network device may provide a client device with a pre-authentication virtual network and a pre-authentication address. Next, a policy may be received in response to the client device authenticating. The client device may then be moved to a post-authentication virtual network based on the policy. A post-authentication address may then be obtained for the client device in response to moving the client device to a post-authentication virtual network. Traffic for the client device may then be translated to the post-authentication address.

Systems and methods are disclosed that enable predictive device mobility session management in a wireless network. A wireless communications network is able to maintain IP session continuity as a wireless device roams among wireless access points of the communications network by ensuring that the wireless device maintains communications with its home wireless access gateway.

A neutral home network (NHN) may support home-routed traffic between a user equipment (UE) and a network of a mobile network operator (MNO) associated with the UE. The NHN may transmit an access point name (APN) that indicates a public land mobile network (PLMN) identifier (ID) to the UE. If the NHN supports home-routed traffic, the NHN may transmit an APN that indicates an MNO PLMN ID. If the NHN does not support home-routed traffic, the NHN may transmit an APN that indicates an NHN PLMN ID. From the APN, the UE may determine whether the NHN supports home-routed traffic. If the NHN supports home-routed traffic, the UE may transmit a packet data network (PDN) connectivity request to the NHN. If the NHN does not support home-routed traffic, the UE may establish a tunnel to the MNO network through Internet access provided by the NHN.

Systems and methods for providing a handoff between technologies are disclosed. An intra-technology handoff occurs where the same integrated chassis handles the session for the different access technologies. In an intra-technology handoff, the same IP address and the session can be maintained through the handoff. The mobile node can undergo a handoff without issuing a registration request in some embodiments. An inter-technology handoff occurs from one integrated chassis to another integrated chassis. The integrated chassis can preserve session and context information in a session manager and in a handoff from one access technology to another the same session manager can be chosen with the session and context information remaining intact even though the access technology has changed. The integrated chassis can provide an access technology handoff where the core network does not notice any change and applications running on or delivered to the mobile node are not effected.
