  • Patent number: 9668210
    Abstract: A multiple access slotted wireless communication system comprising a plurality of terminals and a multi-access receiver is described. The multi-access receiver can decode multiple transmissions in each slot of a frame from terminals in its field of view. Each terminal has an active state for transmitting and an inactive state. After receiving acknowledgement of a successful transmission by the terminal, the terminal enters the inactive state for at least a transmission delay time. This may be the remaining time that the terminal is in the field of view of the multi-access receiver. This may be achieved by the terminal using a probability of transmission to determine whether or not to transmit in the next frame. The terminal may also be configured to select the slot in a frame, and this may be based upon information such as which slots were acknowledged. The receiver may use compression to transmit acknowledgement messages.

  • Patent number: 9655115
    Abstract: In order to solve a problem of an accumulation on the transmission side, a delay on the reception side, and the like at the time of transmission in a communication system such as a wireless LAN system, each communication station in a network transmits a beacon in which information with respect to the network is written and sets a state in which a reception operation is performed during periods of time before and after the transmission of the beacon signal when performing access control not to make communication timing of a packet collide with that of another station by detecting a signal transmitted from another station.

  • Patent number: 9642093
    Abstract: A method for operating a plurality of stations in a cooperative station network, wherein each of the stations transmits signals and receives signals from other stations, includes determining a path loss between at least two of the stations. A carrier sense range for signals of a first station of the stations is determined based on the path loss and received power of signals from the other stations. A load on a dedicated signal exchange channel is determined based on the determined carrier sense range. A maximum output power for the first station is determined based on the determined load. The first station is operated by adjusting the output power of the first station to be, at least on average below the determined maximum output power for the first station.

  • Patent number: 9635581
    Abstract: Local breakout mechanisms can be performed by a femto access point (FAP) to facilitate efficient utilization of backhaul and/or macro networks. In particular, a slave Gateway GPRS Support Node (GGSN) can be integrated within the FAP to directly route the incoming traffic from a user equipment (UE) at the FAP. In one example, Internet bound traffic can be directly routed to the Internet, without employing macro network resources. Further, the system can avoid hairpinning by routing traffic between the UE and a home Local Area Network (LAN) by a anchoring a call or a session in the slave GGSN and facilitate integration of UEs with home applications by employing a UE Digital Home Agent. In addition, the FAP can perform UE-to-UE CS media breakout to facilitate communication between UEs attached to the FAP, without routing the traffic through the core macro network.

  • Patent number: 9609505
    Abstract: The present invention discloses a method for processing USSD service. In this method, when an application server determines that a mobile terminal on a VoLTE network supports USSD operations over IMS, the application server sends an invite message to the mobile terminal, where the invite message includes an identifier of a USSD service; receives an invite response from the mobile terminal, where the invite response carries reply information entered by a subscriber and the identifier of the USSD service; generates, according to the reply information, a message that requests to execute the USSD service, where the message that requests to execute the USSD service carries the identifier of the USSD service; and sends, to a subscriber data server, the message that requests to execute the USSD service, so that the subscriber data server processes the USSD service.

  • Patent number: 9602399
    Abstract: A mesh network, operating as a virtual Ethernet switch, includes multiple nodes operating as Mesh Network Gateway Interfaces (mesh NGIs) enabled for communication with one or more shared access networks. Selectively coupling the multiple NGIs to the same shared access network provides redundancy and load balancing aimed at improving the reliability and performance of the network. A first architecture is based on a gateway group, including a plurality of NGIs enabled to communicate with a single shared access network via a designated broadcast server elected from among the NGIs. A second architecture is based on a plurality of (physical) NGIs enabled to communicate with a single shared access network via one or more designated nodes in the shared access network. The designated nodes, or Mesh Servers (MSs), operate as virtual NGIs, and traffic entering or exiting the mesh flows through one of the MSs, thus improving packet broadcast efficiency.

  • Patent number: 9544727
    Abstract: When a wireless communication device (WCD) is served by a first base station and not by a distant second base station, the WCD may initially be receiving strong pilot strength from the first base station and weak pilot strength from the second base station. Due to the WCD moving into a position where the first base station coverage is obstructed, however, the WCD may detect a quick drop in first base station pilot strength without a corresponding proportional increase in the second base station pilot strength, to the point that the second base station pilot signal is sufficiently stronger than first base station pilot signal that the WCD hands over to the second base station. In response to detecting that scenario, the WCD may report that the location of coverage of the second base station is an uncertain representation of the WCD's location, to help ensure reliable location-based service.

  • Patent number: 9544843
    Abstract: Improved non-cellular (e.g., Wi-Fi) link integration with a cellular (e.g., LTE) network is described. The improved link integration can relate to utilizing an eNodeB device (e.g., residing in a radio access network portion of a cellular network) as an anchor point rather than a packet data network gateway device (e.g., residing in a core network portion of the cellular network) utilized by other approaches. The improved link integration can maintain full compliance with or support for other approaches, and can reduce signaling overhead, simplify quality-of-service management, and/or provide a more rapid reaction to changes of access, particularly in cases where the eNodeB device and a non-cellular access point device are co-located.

  • Patent number: 9531464
    Abstract: A method for assisting the adaptation of a signal from a first node to a second node is provided. The first node communicates with the second node in a wireless communication system over a radio link. The second node has a codebook comprising a set of possible information alternatives for assisting the adaptation of a signal received from the first node. The second node may select an information alternative from the codebook and send it to the first node to assist the first node in adapting the signal. The first node is configured with a number of subsets, each comprising a part of the possible information alternatives. The first node requests that the second node restrict the selection of information alternatives to one of the subsets, and in response, receives an information alternative from the second node that is selected from among the subsets configured according to the configuration request.

  • Patent number: 9531723
    Abstract: A packet processor provides for rule matching of packets in a network architecture. The packet processor includes a lookup cluster complex having a number of lookup engines and respective on-chip memory units. The on-chip memory stores rules for matching against packet data. Each of the lookup engines receives a key request associated with a packet and determines a subset of the rules to match against the packet data. Based on a prefetch status, a selection of the subset of rules are retrieved for rule matching. As a result of the rule matching, the lookup engine returns a response message indicating whether a match is found.
