  • Publication number: 20160119157
    Abstract: A method is executed by a multimedia broadcast multicast services gateway (MBMS-GW) to offload data plane traffic, where the data plane traffic is enhanced MBMS (e MBMS) downlink traffic for a data plane interface Internet Protocol (IP) multicast transport between the MBMS-GW and an enhanced node B (e Node B). The method includes allocating an IP multicast address and a common tunnel endpoint identifier (C-TEID) for an MBMS session between node B (e Node B) and a broadcast multicast service center (BM-SC). The method also includes configuring the at least one network element to match an IP address and a user datagram protocol (UDP) port of incoming data plane traffic, to modify the IP address and UDP port to the IP multicast address and associated UDP port, and to push a general packed radio service (GPRS) tunneling protocol (GTP) user data (GTP-U) header including the C-TEID onto the data plane traffic.

  • Publication number: 20160072850
    Abstract: The present disclosure relates to methods and devices, of activating lawful interception. According to the present disclosure, a gateway comprises a controller for controlling, using a flow control protocol, the flow of packets through a switch controlled by the gateway. The switch receives (S11), from the controller, a lawful interception activation request, comprising a target identity; activates (S12), in response to said request, lawful interception on a target identified by the target identity; duplicates (S13), in the switch, packets targeting the target; encapsulates (S14) the duplicated packets with an additional header; and forwards (S15) duplicates from the switch directly to the lawful interception service provider entity (1) for further distribution to a Lawful interception Agency.

  • Publication number: 20160011648
    Abstract: The embodiments herein relate to a method in a first network unit (101) for handling states in a network (100). The first network unit (101) is adapted to supervise power in the network (100). The first network unit (101) receives a work-load report from one or more of a plurality of second network units (105). The second network units (105) consume power. When the second network units (105) are awake and the workload is below a threshold, the first network unit (101) transmits a sleep request to at least one of the second network units (105) to change from awake to sleep. When the plurality of second network units (105) are asleep and the workload has reached or is above the threshold, the first network unit (101) transmits a wakeup request to at least one of the second network units (105) to change from sleep to awake.

  • Patent number: 9231874
    Abstract: The embodiments herein relate to a method in a network node (110) for handling TCP traffic in a packet switched network (100). The network node (110) receives TCP traffic from a mobile node (101). The TCP traffic comprises an original window size. The network node (110) replaces the original window size with an optimized window size when the network node (110) comprises information about dropped TCP traffic and when the original window size is larger than the optimized window size. The network node (110) sends the TCP traffic comprising the optimized window size to a correspondent node (105) in the packet switched network (100) indicating an amount of TCP traffic receivable by the mobile node (101).
