  • Patent number: 9338674
    Abstract: A system for optimizing communications on a radio network by altering transitions between different link states that includes several modules. The activity, environment, and load module monitor monitors the link layer based on spectral-load metrics and radio-link metrics. The state transition control module determines when user equipment transitions between different states based on the type of user equipment, user equipment battery life, whether the user equipment is connected to an alternating current outlet, a spectral cost, and a backhaul cost. The channel state influencer module uses any of direct messages, ping messages, and keep-alive messages to influence the link state. The policy and preference handler enables or disables transitions based on the bearer technology type, the type of user equipment, the user's subscription plan, and the load level on the network.

  • Patent number: 9325465
    Abstract: A method and base station (600) of a first cell (602), for—controlling inter-cell interference in a cellular network when Discontinuous Reception, DRX, is applied for User Equipments, UEs. The base station selects a DRX scheme with active periods that are separated in time from active periods of a DRX scheme used for UEs in DRX mode in a neighboring second cell (806). The selected DRX scheme is then used for a first UE (604) in DRX mode in the first cell to avoid interference between transmissions of signals in the active periods to the first UE in the first cell and transmissions of signals in active periods to the UEs in the neighboring second cell.

  • Patent number: 9319851
    Abstract: A method of supporting group communication over LTE MBMS is provided. A UE first establishes a unicast Evolved Packet Service (EPS) bearer in an LTE network for group communication. The UE belongs to a communication group having a communication group ID. The UE receives access information from the network for monitoring downlink (DL) multicast traffic of the DL group communication based on a multicast decision. The UE is then ready for monitoring a multicast Multimedia Broadcast Multicast Service (MBMS) bearer for receiving the DL multicast traffic. The multicast MBMS bearer is associated with a Temporary Mobile Group Identifier (TMGI), and wherein the TMGI is associated with the communication group ID. The UE de-multiplexes DL traffic received either from the multicast MBMS bearer or from the unicast EPS bearer into a single group communication application.

    Abstract: A coexistence system including a first transceiver module and a second transceiver module. The first transceiver module generates an uplink indication signal and, subsequent to a first predetermined period after having transmitted the uplink indication signal, transmits first signals from a first network device to a second network device during an uplink period. The uplink indication signal indicates the first signals are to be transmitted subsequent to the first predetermined period. The first signals and the second signals respectively conform to first and second wireless communication standards. The second transceiver module, based on the uplink indication signal, transmits: the second signals during a portion of the uplink period unused by the first transceiver module; or a signal indicating a second predetermined period. The second predetermined period indicates to the second network device not to transmit the second signals to the second transceiver module during the second predetermined period.

  • Patent number: 9219597
    Abstract: A method is described for the transmission of data among devices (D1, D2, . . . Di, . . . Dn) connected to a communication channel (1) through sequences containing at least two symbols, one dominant (“0”) and one recessive (“1”). According to this transmission method, one (DTSG) of the devices connected to the communication channel (1) has the function of time slot generator and it transmits on the communication channel (1) with a transmission frequency (f) a sequence of symbols, each defining a time slot in a sequence of time slots. The sequence of symbols comprises at least a series of recessive symbols (“1”). When one of the devices (Di) has to transmit on the communication channel (1), it generates a sequence of symbols, synchronized with the sequence of time slots generated by the time slot generator device (DTSG) and comprising at least one dominant symbol (“0”).
