  • Patent number: 10193650
    Abstract: Methods and apparatus for allocating scrambling codes to cells of a wireless network. In an example method, current scrambling code allocation information for a plurality of cells and network configuration information for a radio access network are received (310). A reallocation of scrambling codes to the plurality of cells is computed (320), based on the current scrambling code allocation information and the network configuration information, using a metaheuristic algorithm. A change in scrambling code for at least one of the plurality of cells is then triggered (330), based on the computed reallocation. In some embodiments, the metaheuristic algorithm is based on an objective function that comprises a summation of interference metrics for each of the plurality of cells, wherein the interference metrics depend on scrambling code allocations to the plurality of cells. In some embodiments, a simulated annealing metaheuristic is used.

  • Patent number: 10182465
    Abstract: A control node (140; 150) of a cellular network establishes one or more control plane sessions with a gateway node (160). On the basis of these one or more control plane sessions with the gateway node (160), the control node (140; 150) also establishes one or more control plane sessions with one or more radio access network nodes (112, 114; 122, 24) to control multicast transmissions by the one or more radio access network nodes (112, 14; 122, 124). Further, the control node (140; 150) detects a connection failure to the gateway node (160). When detecting the connection failure, the control node (140; 150) starts a first timer. Further, also the gateway node (160) detects the connection failure. When detecting the connection failure, the gateway node (160) starts a second timer. The second timer is configured with a longer duration than the first timer.

  • Patent number: 10165487
    Abstract: This disclosure relates to a system and method for offloading selected data to an alternate communication network. The offloading provides another route for selected packet traffic that can relieve the burden on a mobile operator's network, such as the backhaul and core networks. As the proliferation of data rich content and increasingly more capable mobile devices has continued, the amount of data communicated over mobile operator's networks has exponentially increased. Upgrading the existing network that was designed for voice calls is not desirable or practical for many mobile operators. This disclosure provides systems and methods for offloading data to the Internet or another IP network to relieve congestion on the mobile operator's network.

  • Patent number: 10141974
    Abstract: A frequency-hopped spread-spectrum multiple-access (FHSS-MA) wideband transceiver may support frequency-division multiple-access (FDMA) functionality by including a plurality of digital chains corresponding to FHSS-MA physical channels, individually and dynamically compensated for in-phase/quadrature imbalance in the transmit and/or receive portion. A FHSS-MA transceiver supporting FDMA functionality may coordinate FH sequence selection among FHSS physical channels to minimize inter-channel interference while also supporting legacy FHSS-enabled devices (e.g., Bluetooth®). The FHSS-MA transceiver may be incorporated into a wireless bridge device to facilitate low-latency communications over wireless local-area networks (WLANs), wireless wide-area networks (WWANs) or broadcast, with multiple FHSS-enabled devices that may be paired with the wireless bridge device using FHSS-MA channels. The wireless bridge device may enable a FHSS-enabled device to re-pair with a personal device.

  • Patent number: 10098066
    Abstract: The embodiments of the disclosure include methods and apparatus that provide back-off procedures for avoiding device/network resource depletion in bad network conditions. A device user may selectively enable an auxiliary back-off procedure that extends the time between network service requests. For example, the auxiliary back-off procedure may be used if the device determines an attach request is unsuccessful when a reject message is received from the network and the reject message indicates a reject cause for which the device has no defined back-off to follow. The auxiliary back-off procedure may be also be used if the device determines that a service request is unsuccessful when the service request is ignored, i.e. no response is received from the network, or, when a service request reject is received from the network and the reject message indicates a reject cause for which the device has no defined back-off to follow.

  • Patent number: 10070463
    Abstract: A wireless telecommunications method, a computer program product and network nodes are disclosed. The wireless telecommunications network node method comprises on a failure to establish a connection after initiating a RACH procedure, repeatedly transmitting a RACH preamble signature using a defined set of resource blocks of an uplink channel. In this way, when a conventional RACH procedure fails to establish a connection with the network, a modified RACH procedure is instead initiated. This modified RACH procedure transmits a RACH preamble signature repeatedly using a repeating set of resource blocks which are repeatedly allocated from the uplink channel. This enables the RACH preamble signature to be repeatedly transmitted so that the energy from these repeated transmissions may be combined by the network in order to detect the presence of the RACH preamble signature transmitted by network nodes in a poor coverage area such as, for example, an MTC device located in a basement.

  • Patent number: 10057409
    Abstract: Methods and systems for monitoring communication of mobile communication terminals, such as cellular phones. An off-air monitoring system reconstructs both directions of a call conducted between two mobile terminals by receiving only downlink channels. The off-air monitoring system receives multiple downlink transmissions transmitted by base stations in a wireless communication network. The system uses the received downlink transmissions to reconstruct the bidirectional call content of calls conducted between wireless terminals. In order to reconstruct the bidirectional content of a given call, the system identifies and correlates the two downlink transmissions of that call from among the multiple received downlink transmissions.
