  • Patent number: 10070357
    Abstract: Techniques described herein may enable Evolved Packet Core (EPC) devices (e.g., Mobility Management Entities (MMEs), Serving Gateways (SGWs), or Packet Data Network Gateways (PGWs)) to transfer a connection with a User Equipment (UE) from one EPC device to another EPC device without a break in service for the UE. The transfer may occur in response to an EPC device being overloaded, an EPC device being added or removed from a logical group of EPC devices, or in response one EPC device becoming more appropriate for the UE than another EPC device (e.g., due to a change in the geographic location of the UE). EPC devices may be implemented as virtual network functions, and the transfer of the UE may occur while the UE is in an active mode or an idle mode.

  • Patent number: 10057013
    Abstract: A two-stage signaling concept for a datastream to be transmitted from a transmitter to a receiver is proposed. At the transmitter side, a plurality of frame headers are generated, each frame header including data transmission parameters for payload data. A super-frame header for a super-frame is generated. The super-frame includes a plurality of frames, each frame including one of the frame headers and payload data. The super-frame header indicates a set of super-frame-constant frame header transmission parameters for the frame headers of the plurality of frames of the super-frame. A receiver evaluates the super-frame header of to obtain the super-frame-constant frame header transmission parameters, which are then used to evaluate the plurality of frame headers PLH to retrieve the data transmission parameters. The proposed concept provides added flexibility, less signaling overhead, and/or an option of improved receiver performance at low SNR levels.

  • Patent number: 9979595
    Abstract: Subscriber management and network service integration for an access network is described in which a centralized controller provides seamless end-to-end service from a network to access nodes. For example, a method includes dynamically establishing a control channel between the centralized controller and an access node, and establishing a transport label switched path (LSP) transport network packets between the access node and the network node. The access node sends, via the control channel, an endpoint indication message that indicates that an endpoint that has joined the network at the access node. The access node receives a pseudo wire request message via the control channel to install forwarding state for creating a pseudo wire for providing one or more network services to the endpoint. The access node receives a direct switch message via the control channel to configure the access node to map traffic received from the endpoint to the pseudo wire.
