| 20100027443 | ESTABLISHING COMMUNICATION PATHWAYS BETWEEN INFRASTRUCTURE DEVICES IN A GROUP COMMUNICATION SYSTEM IMPLEMENTED OVER A WIDE AREA NETWORK - A method and apparatus is provided for establishing communication pathways between infrastructure devices in a wide area communication network prior to transmission of a group message packet by a source wireless communication device (WCD). In one implementation, the infrastructure devices (IDs) can include a home ID of the source WCD, a first ID and a second ID. A home steward module (HSM) of the source WCD generates a distribution list (DL) for communications from the source WCD to a first communication group (CG), and communicates it to an envoy packet duplicator module (EPDM) located at the first ID. The first CG includes, for example, a first destination WCD. A first network socket of the EPDM is communicated from the HSM to a second envoy module (located at the second ID) for the first destination WCD. The HSM maps a second network socket for the second envoy module to an identifier of the first destination WCD, and communicates this mapping to the EPDM. A first communication connection can then be established between the first network socket and the second network socket. | 02-04-2010 |
| 20100027453 | COMMUNICATING A GROUP MESSAGE PACKET OVER A WIDE AREA NETWORK - A method and apparatus is provided for communicating a group message packet among wireless communication devices (WCDs) over a wide area communication network that includes a first infrastructure device (ID), a second ID and a third ID. A first communication connection is established between an envoy packet duplicator module (EPDM) that is in communication range of a source wireless communication device (WCD) and a first envoy module implemented at the first ID that is in communication range of a first destination WCD. The EPDM is implemented at the third ID. The source WCD communicates a group message packet from the source WCD to a third envoy module implemented at the third ID, which forwards the group message packet to the EPDM. The EPDM generates a first copy of the group message packet destined for the first destination WCD, and communicates the first copy of the group message packet to the first envoy module. | 02-04-2010 |

| 20100082829 | SYSTEM AND METHOD FOR PEER-TO-PEER WIDE AREA NETWORK COMMUNICATION - A method of operating a peer to facilitate fast group communication between subscribers in a peer-to-peer wide area network is disclosed. In the peer-to-peer wide area network, each of the subscribers are affiliated to a talkgroup, and further registered to at least one peer within the peer-to-peer wide area network. In operation, the peer exchanges messages with other peers to determine that one or more peers listed in a talkgroup topology is still active. When the peer receives a media for a talkgroup from a subscriber affiliated to the talkgroup, the peer duplicates the media for the talkgroup, and unicasts the duplicate media to the one or more peers that are listed as active in the talkgroup topology to enable the one or more peers to deliver the media to the respectively registered subscribers affiliated to the talkgroup. | 04-01-2010 |

| 20110075771 | METHOD AND APPARATUS FOR MITIGATION OF INTERFERENCE - A method of reducing error in transmissions received in a receiver is provided. A transmission containing a synchronization signal is inputted through a first filter to a synchronization correlator, to generate a timing error of the synchronization signal. An amount of delay of the synchronization signal sufficient to reduce the timing error is determined. The transmission is delayed by the amount of delay by being passed through at least a second, variable filter whose delay is determined using a stochastic gradient algorithm. The synchronization correlator may also generate a deviation error of the synchronization signal and determine an amount of deviation correction sufficient to reduce the deviation error as well as generating a frequency error of the synchronization signal and determining an amount of frequency correction sufficient to reduce the frequency error. | 03-31-2011 |
| 20110075774 | METHOD AND APPARATUS FOR MITIGATION OF INTERFERENCE - A signal is provided to each of nominal, higher and lower primary filters in a receiver. The nominal, higher and lower primary filters have different center frequencies and a bandwidth B1 and bandwidths B2, respectively and a bandwidth offset B0, with B2=B1+B0. Signal recovery is performed on the output of each primary filter to obtain recovered signals and error values each associated with one of the primary filters. Each error value is provided to a secondary and tertiary filter, to generate a signal criterion, and whose output is measured to generate a quality metric, respectively, associated with each recovered signal. The recovered signal associated with the nominal primary filter and any other recovered signal having an associated signal criterion below a threshold value is selected and the selected recovered signal which has the lowest associated quality metric is chosen. | 03-31-2011 |
