  • Patent number: 9961045
    Abstract: The present disclosure a service path changing method and apparatus, including: determining, by an MME, that a UE needs to be handed over from a first AG to a second AG; and instructing, by the MME, the UE to notify, according to bearer information used to perform service transmission between the second AG and the UE and assigned by the second AG, a service peer end that an IP address of the UE is changed from a first IP address assigned by the first AG to a second IP address assigned by the second AG.

  • Patent number: 9954715
    Abstract: The present invention provides a preamble that is inserted into an OFDMA frame and has a common sequence for all the base stations participating in a transmission. The subscriber station performs fine synchronization using the common sequence on the common preamble, and the resulting peaks will provide the locations of candidate base stations. The base station specific search is then performed in the vicinities of those peaks by using base station specific pseudo-noise sequences. With this two stage cell search, the searching window is drastically reduced. The preamble is matched to known values by a respective receiver to decode the signals and permit multiple signals to be transferred from the transmitter to the receiver. The preamble may comprise two parts, Preamble-I and Preamble-2, which may be used in different systems, including multioutput, multi-input (MIMO) systems.

  • Patent number: 9929768
    Abstract: A reconfigurable TDD-FDD multiplexer operates in a TDD mode and a FDD mode. The TDD-FDD multiplexer includes an interdigital quadruplexer in series with a one-pole three-throw RF switch. The interdigital quadruplexer includes of two V-band filters, connectable to a transmitter and a receiver, respectively, for TDD mode duplexing, and two E-band filters, connectable to a transmitter and a receiver, respectively, for FDD mode duplexing. The E-band filters include an E-band transmitting filter that passes an E-band transmitting frequency band, and an E-band receiving filter that passes for an E-band receiving frequency band offset from the E-band transmitting frequency band. Switching between the V-band receiving filter and V-band transmitting filter enables TDD duplexing functionality at V-band frequencies. Switching to the two E-band filters enables FDD duplexing functionality at E-band frequencies.

  • Patent number: 9929897
    Abstract: The problem of being unable to run microBFD using an IPv6 address over any member links of a layer 2 LAG when the LAG is DOWN (and its IPv6 address becomes or is TENTATIVE), is solved by running DAD for the address configured for the microBFD once the individual link is in DISTRIBUTING or STANDBY state and triggering (or starting) microBFD once the DAD for that address completes successfully. Further, member links of the LAG may be permitted to continue running microBFD even if the LAG interface is DOWN and even if some other member links (but not all member links) of the LAG are DOWN.

  • Patent number: 9820292
    Abstract: Embodiments herein relate to a method performed by a network node for enabling the network node to communicate with a set of one or more wireless communication devices (WCDs) and to a method performed by a WCD for communicating with the network node. The network node selects a subframe for carrying data to at least one of the WCDs included in the set of one or more WCDs. The network node determines whether an activity indicator specific to the set of one or more WCDs should be transmitted to the set of one or more WCDs; and, in response to determining that the activity indicator specific to the set of WCDs should be transmitted, the network node transmits the activity indicator in the selected subframe and/or in one or more subframes that precede the selected subframe data. The network node further transmits the data to the at least one of the WCDs included in the set of one or more WCDs in the selected subframe.
