  • Patent number: 9370037
    Abstract: A first device associated with an evolved packet core network receives a first update request from a second device associated with the evolved packet core network. The first update request is associated with a communication session previously provided between the first device and the second device, and the first update request is generated based on a voice/video request. The first device generates an update answer in response to the first update request, where the update answer includes a code requesting that the communication session be restored between the first device and the second device. The first device receives, based on the code, a second update request from the second device, where the second update request includes session information associated with the communication session. The first device restores, based on the session information, the communication session between the first device and the second device to create a restored communication session.

  • Patent number: 9369322
    Abstract: A method of decoding a received SC-FDMA symbol in a receiver in a OFDM communication system is described. The method comprises calculating an approximate constellation energy {circumflex over (K)} from channel matrices Hi for all subcarriers i, a noise covariance matrix S, and a data signal power matrix C associated with the OFDM symbol, an approximate constellation energy {circumflex over (K)}. The approximate constellation energy {circumflex over (K)} is calculated according to: Q i = H i H ? S - 1 ? H i ; Q ^ = 1 N sc ? ? i = 0 N sc - 1 ? Q i ; K ^ = diag ? ( ( Q ^ + C - 1 ) - 1 ? Q ^ ) The method further comprises decoding the received symbol using at least the associated approximate constellation energy {circumflex over (K)}. Also, a receiver, an apparatus, an OFDM communication system and a computer program product for such decoding are described.

  • Patent number: 9363044
    Abstract: An arrangement is described for adapting outer loop precoder phase combiner in a radio communication system having coordinated multipoint transmission. In the arrangement ACK/NACK-message received as a response to a transmitted data packet is used for adapting the phase. When a NACK-message is received the phase may be adapted or it may be further determined if the error was due to error in channel code or due to destructive inter-point signal combining. If the error was due to destructive combining the phase is adjusted.

  • Patent number: 9350734
    Abstract: A gateway may respond to a data-connection request, relating to a request to establish a packet data connection for a requesting wireless communication device (WCD), based on a request rate determined from the number of other data-connection requests that the gateway has received during a particular period of time. If the request rate is below a first threshold, the gateway may initiate an authentication process to authenticate the requesting WCD and either accept or reject the data-connection request based on whether the authentication process is successful or unsuccessful. If the request rate is greater than the first threshold and less than a second threshold, the gateway may accept the data-connection request without initiating the authentication process. If the request rate is greater than the second threshold, the gateway may reject the data-connection request without initiating the authentication process.

  • Patent number: 9331925
    Abstract: In one embodiment, methods are described to measure bandwidth limits through multiple test sites. A testing quantity of network packets is generated, the network packets are sent through a service provider network to a plurality of receivers at a testing transmission rate that exceeds an upstream transmission rate limit of the service provider network, a report indicating a received number of packets is received from each of the plurality of receivers, and an upstream transmission rate limit of the service provider network is determined based on the testing transmission and the reports. By using multiple test sites, potential bottlenecks at any one test site are reduced. A similar method can be used to calculate a downstream transmission rate limit. Once measured, the bandwidth limits may be used to adjust quality of service on an edge router or compared against a known service level agreement of the service provider network.

  • Patent number: 9306733
    Abstract: A method of synchronizing a time division duplex (TDD) multi-line, multi-carrier data communication system is provided. Synchronization is established using unique pseudo-random bit sequences (PRBS) from a common generator polynomial having different seed values. Due to low correlation of PRBS generated with different seed values, a remote unit can only synchronize to its intended signal effectively mitigating far-end and near-end crosstalk impact of large bandwidth very high speed digital subscriber lines (VDSL).

  • Patent number: 9300589
    Abstract: In response to a detected loss of previously transmitted information by an apparatus communicating with a remote device (e.g., using TCP), the rate of transmission of information is increased by the apparatus in response to attributing the detected loss of previously transmitted information as not being caused by congestion. This attribution of the packet loss is typically determined based on roundtrip delays between sent information and received corresponding acknowledgments, which may be used directly or indirectly, such as by estimating network queuing delays based on the measured roundtrip delays.

  • Patent number: 9301300
    Abstract: The present invention is a method and system adapted to facilitate, between a mobile station (MS) and network, an indication of support for reduced time transmission interval (RTTI). The MS can provide a base station system (BSS) with an indication of its multislot capability within an access burst sent at the start of a contention based access. In another aspect, the MS can indicate support for a new Immediate Assignment message as the conventional Immediate Assignment message can only assign single timeslots. The present invention enables the Radio Access Network (RAN) to assign RTTI and more than one timeslot for GPRS/EDGE temporary block flows (TBFs) during an Access Grant Channel (AGCH) assignment. The method of the present invention can be implemented in a computer program product or distributed software adapted to be loaded into at least one or a plurality of memory locations and executed by at least one or a plurality of respective computer processors.
