Abstract: A system and method that routes special number calls from communications devices, including VoIP communications devices, to an answering point that is selected based on a parameter. A peering network effects parameter-based routing of calls to a pre-assigned answering point, wherein the voice path and the signaling paths are set up simultaneously. A gateway in the peering network is connected to the service provider switch and receives special number calls. The gateway queries a pre-provisioned parameter server that determines call routing information for the particular communications device. The gateway then selects another gateway, or, optionally, a selective router access provider network, based on the routing information and delivers the call thereto. The other gateway or selective router access provider network is connected to a router in the destination network and delivers the call and the call parameters to the router.

Abstract: Techniques are disclosed for signaling a pattern of cyclic shifts and orthogonal cover codes for use by a wireless device in multi-layer transmissions. In one example method, a signal includes B bits for identifying a reference signal is received, wherein each of several available reference signals is defined by a cyclic shift and an orthogonal cover code. The B bits are used to identify the cyclic shift and orthogonal cover code according to pre-determined tables that map each value of the B bits to a pattern of cyclic shift and orthogonal cover code combinations for a multi-layer transmission scheme. The patterns for the multi-layer transmission scheme include first and second patterns based on the same cyclic shifts, but where some, but not all, of the cyclic shifts in the first pattern are associated with the same corresponding orthogonal cover codes in the second pattern.

Abstract: Failover controllers help maintain user-perceived continuous connectivity for users of a geographically dispersed flat network when part of that network becomes unavailable, even though flat network packets are not WAN-routable. One such controller has local and remote flat network ports, at least one WAN port, and failover capability to WAN(s) utilizing encapsulation when the flat network is partially or fully unavailable. The failover procedure uses a packet origin table built automatically from incoming packets and from double-tunneled ARP requests. A monitor indicates whether the flat network is fully available (up) or not fully available (down).

Abstract: An SS7-based call protocol conversion gateway that translates between circuit-switched SS7 protocols and session initiation protocol (SIP) oriented protocol, allowing an E911 call initiated over a switched network to be routed by a VoIP network. The SS7-based call protocol conversion gateway provides a PSAP with MSAG quality (street address) information about a VoIP dual mode phone user without the need for a wireless carrier to invest in building out an entire VoIP core. Thus, wireless carriers may continue signaling the way they are today, i.e., using the J-STD-036 standard for CDMA and GSM in North America, yet see benefits of a VoIP network core, i.e., provision of MSAG quality location data to a PSAP.

Abstract: Methods for contention-based transmission with contention-free feedback for reduced latency in LTE Advanced networks and an enhanced PUCCH are generally disclosed herein. User equipment (UE) may transmit a contention sequence on a physical uplink control channel (PUCCH) to an enhanced-Node B (eNB) and may concurrently transmit data requesting uplink resources on a physical uplink shared channel (PUSCH) to the eNB. The contention sequence is transmitted on the PUCCH in accordance with a format that is assigned by the eNB. The contention sequence is either randomly selected by the UE or assigned by the eNB. When the contention sequence and data are not successfully received by the eNB, the UE may fall back to a more conventional random access channel (RACH) procedure for uplink resource allocation.
