Abstract: Techniques to support emergency voice-over-Internet Protocol (VoIP) calls are described. The techniques may be used for various 3GPP and 3GPP2 networks, various location architectures, and various types of User Equipment (UE). A UE communicates with a visited network to send a request to establish an emergency VoIP call. The UE interacts with a location server instructed by the visited network to obtain a first position estimate for the UE. The UE performs call setup via the visited network to establish the emergency VoIP call with a PSAP, which may be selected based on the first position estimate. The UE may thereafter perform positioning with the location server to obtain an updated position estimate for the UE, e.g., if requested by the PSAP.

Abstract: A method is disclosed for the collection of performance metrics by establishing service operations administration and maintenance (OAM) sessions between an actuator and a plurality of reflectors in a communication network. Test packets from an actuator simultaneously reach a plurality of reflectors along a test path. Each single test packet results into a plurality of test results, one per reflector, with quasi-synchronous performance metrics to sectionalize a network and more efficiently isolate fault or performance problems without the need for additional test packets to isolate the issue. Another method is disclosed wherein an actuator generates and transmits a plurality of simultaneous test packets, one per NID device, resulting into a plurality of test results, one per reflector, with quasi-synchronous performance metrics to sectionalize a network and more efficiently isolate fault or performance problems without the need for additional test packets to isolate the issue.

Abstract: Networked devices are arranged to play content such as audio and video content in synchronization. A synching device receives a packet from an initiating device over a network. The packet may include an identifier of content to play, such as a URI, and an indication of when to play the content. A local clock time to play the content is determined based on a time of a local clock of the first device and the indication of when to play the content. The synching device obtains from a server the content based on the received identifier, and plays the content in synchronization with the initiating device based on a time on the local clock and the local clock time to play the content. In some embodiments, the synching device also adjusts a clock speed of the local clock reference to control rate of playback of the content.

Abstract: Capacity enhancement of a direct communication link using a variable redundancy delivery network. An estimated information rate between a source node and a terminal node may be partitioned into a first information rate provided via the direct communication link and a second information rate to be provided via the variable redundancy delivery network. One or more parameters of the variable redundancy delivery network may be calculated to provide the second information rate based on a non-uniform probability density of messages requested by the terminal node. Capacity and reliability of storage media devices in the variable redundancy delivery network may be traded off to provide the second information rate. The variable redundancy delivery network may implement various coding schemes and per-message coding rates that may be determined based on the non-uniform probability distribution of the source message library.

Abstract: A method and system for dynamically reconfiguring an air interface that defines a continuum of frames each divided into a sequence of transmission time intervals (TTIs). The air interface is initially configured according to a first radio access technology (RAT). The base station then detects that at least a threshold extent of wireless client devices (WCDs) served by the base station on the air interface support operation according to a second RAT. And in response, the base station reconfigures the air interface so that certain TTIs per frame instead operate on a second RAT, with the remaining TTIs per frame still operating on the first RAT. The base station then serves WCDs that support the second RAT in the TTIs now configured according to the second RAT, while continuing to serve other WCDs according to the first RAT in the remaining TTIs configured according to the first RAT.

Abstract: The invention provides a packet loss detection system that in near-real time detects packet loss and reports the identities of the lost packets. The identities of the lost packets are based on a set of packet-specific information that includes five-tuple flow information of the packet and other unique packet identifiers. A set of meters are placed at various vantage points in the network, each meter generates digests summarizing all the traffic passing through itself. The digests are exported to a collector/analyzer, which decodes the digests and performs an analysis to detect packet losses and to determine the lost packets' identities. The collector compares between the traffic digests generated by all the meters surrounding the segment. Mismatches among the digests indicate packet losses. The collector restores the identifiers of the lost packets by further decoding the mismatches between the digests.
