  • Patent number: 9794840
    Abstract: Systems and methods are described for determining candidates for handover of wireless devices in a wireless network. A first access node in communication with one or more wireless devices may receive signal information for second access nodes from the wireless devices. A communication link between the first access node and each second access node may be used to transmit second access node network characteristics to the first access node. The first access node may store information about second access nodes in a neighbor relation table. If a removal condition is satisfied, one or more second access nodes may be removed from the first access node neighbor relation table and may be blacklisted. Blacklisted second access nodes may be monitored for improvements in signal information or network characteristics. Improved second access nodes may be removed from the blacklist based on a comparison with threshold values for signal information and network characteristics.

  • Patent number: 9787777
    Abstract: Methods and apparatus for wireless communications in regional networks, e.g., ad hoc peer to peer networks, are described. Wireless communications devices transmit and monitor for presence indicator signals broadcast from other peer communications devices in its local vicinity. A wireless communications device maintains a list of discovered devices in its vicinity. A first wireless communications device transmits a paging signal directly over an airlink to a second communications device, which is on its list and to which it desires to send data units, e.g., user data in a peer to peer traffic segment. In response to a received paging response signal from the second device, the first device transmits data units, intended for the second device, to a third device, which acts as an intermediary node. The power level for the data unit signal is controlled to be lower than the power level used for the paging signal. FIG.

An SHDC device provides physical layer seamless hand-off and obtain diversity signal-to-noise ratio (SNR) gain. When additional antennas are available for standby or other reasons, it may be beneficial for a number of satellite antennas to collectively utilize additional SHDC devices to achieve higher diversity SNR gains under normal operational considerations. The asymptotic SNR gains are those obtained when receiver antenna noise dominates transponder and sky noises. According to exemplary embodiment of the present invention, N satellite antennas may collectively utilize N?1 SHDC devices. For example, 3 satellite antennas may collectively utilize 2 SHDC devices.

  • Patent number: 9743132
    Abstract: A redirection device for remote streaming media reroutes media content sent to the receiving device, typically located in the home of the subscriber, to the subscriber's mobile device such as a laptop or smartphone. Remote media streaming provides media recipients with capabilities for out-of-home (OOH) viewing for remotely rendering media content from a subscriber based receiving device to a personal electronic device. The remote streaming redirects media that has already been received by the subscription based receiving device, such that the redirection device forwards a rendering signal including the requested content to the rendering device based on the reported location. The redirected media stream therefore emanates from the redirection device as an independent transmission of content already received by the receiving device, and not as a separate transmission of media content from the content provider.

A Measurement Request field corresponding to a beacon request contains a measurement duration value and channel number for which the request applies. The beacon request permits a scan mode. In Active Scan mode, the measuring station (STA) transmits a probe request with a broadcast SSID. In Passive Scan mode, the measuring STA passively receives on the specified channel and return a beacon report containing one information element for each STA from which it detects a beacon or probe response. In Beacon Table mode, the measuring STA returns a beacon report containing the current contents of its beacon table without performing additional measurements.

  • Patent number: 9660789
    Abstract: A method performed by a central network node includes instructing one of a first network node and a second network node to transmit to a first wireless device. The central network node receives a first Channel Quality Indicator, CQI, and a third CQI sent by the first wireless device. The first CQI has been computed by the first wireless device based on a first unique signal transmitted by the first network node. The third CQI has been computed by the first wireless device based on a second unique signal transmitted by the second network node. The central network node identifies the one of the first and the second network nodes having a better channel quality, based on the received first CQI and the third CQI. The central network node sends a first message to the identified network node, instructing it to transmit to the first wireless device.

  • Patent number: 9629048
    Abstract: The present invention relates to a method for processing information between mobile communication systems in order to prevent the degradation of user-experienced performance when different types of mobile communication networks are used. The method for processing information at user equipment (UE) to improve user-experienced performance of a mobile communication system includes performing a data communication through a first network and receiving, from a policy server, a routing policy including a validity condition which is information about a condition of designating a UE status for handover. The method further includes, in the handover, if a searched second network satisfies the validity condition, performing the data communication through the second network. Accordingly, a network for data transmission can be selected using a routing policy created in consideration of a UE status or a network status, thereby enhancing user-experienced performance.

  • Patent number: 9615310
    Abstract: A mobile communication system includes a CSG cell which is accessible by a CSG member, a hybrid cell which is the CSG cell where a non-CSG member is also allowed access at the same time, and a mobile terminal which is subscribed as the CSG member and connected to the CSG cell or the hybrid cell as the CSG member. Even in a case in which a subscription time period has expired, the mobile communication system enables the mobile terminal to continue the connection. When the subscription time period for the CSG member expires, in case of the mobile terminal's connection to the CSG cell, the CSG cell initiates a handover, in case of the mobile terminal's connection to the hybrid cell, the hybrid cell changes treatment for the mobile terminal from treating the mobile terminal as the CSG member to treating the mobile terminal as the non-CSG member.
