Patent number: 8483701Abstract: Systems and methods for controlling congestion in a cellular communication system (20) are provided. A method includes measuring an inter-arrival time for a plurality of communication packets in at least one user equipment within the communication cell and calculating an average value for the measured inter-arrival times (102). The method further includes determining the average value over each of a plurality of time periods and identifying a congestion condition when the determined average value exceeds a predetermined value over the plurality of time periods (104, 106).Type: GrantFiled: July 16, 2010Date of Patent: July 9, 2013Assignee: Pine Valley Investments, Inc.Inventors: Peter Monnes, Thomas Andrew Hengeveld, Melvin Kevin Stubbings

Patent number: 8422447Abstract: Systems (200) and methods for providing voice communications over a cellular network (204, 212). A call setup message is communicated from a first communication device (FCD) to a second communication device (SCD) on a first communications channel (FCC) in a cellular network (CN) at a first data transfer rate (FDTR). In response to the call setup message, a stimulator packet is communicated to the CN on FCC at FDTR. The stimulator packet includes data of an amount that equals or exceeds a threshold value. In response to the stimulator packet, FCD (202, 214) and CN transition from a first channel mode to a second different channel mode. In the second channel mode, data is transmitted on a second communications channel (SCC) in CN at a second data transfer rate (SDTR) different than FDTR.Type: GrantFiled: August 27, 2010Date of Patent: April 16, 2013Assignee: Harris CorporationInventors: Peter Monnes, Thomas Andrew Hengeveld, Micael Martell

Patent number: 8274933Abstract: A wireless communication network is provided that includes a plurality of communication cells each defined by at least one communication coverage area and a plurality of access points each corresponding to a different one of the plurality of communication cells. Each access point is configured to communicate on a first frequency with at least one of (i) a subscriber in the at least one communication coverage area in a first communication cell and (ii) a subscriber in a second communication cell. Each access point is further configured to communicate on a second frequency with an access point in a third communication cell.Type: GrantFiled: February 8, 2011Date of Patent: September 25, 2012Assignee: Pine Valley Investments, Inc.Inventors: Gregory Newell Henderson, Thomas Andrew Hengeveld, Daniel Wayne Ericson, Dennis Michael Martinez, Reid Henry Johnson

Patent number: 8169983Abstract: A transcoder architecture and method for transcoding in land mobile radio (LMR) systems are provided. The LMR system includes a first communication site configured to communicate using a first LMR communication protocol and a second communication site configured to communicate using a second LMR communication protocol. The LMR system further includes a transcoder configured to receive LMR content from the first communication site communicated using the first LMR communication protocol and digitally convert the LMR content to the second LMR communication protocol to be communicated to the second communication site.Type: GrantFiled: August 7, 2006Date of Patent: May 1, 2012Assignee: Pine Valley Investments, Inc.Inventors: William Oscar Janky, Thomas Andrew Hengeveld, Dennis Michael Martinez

Patent number: 7917748Abstract: A method for distributing group secrets (e.g., group ID and password combinations) for use in communication systems such as trunked radio communication systems. A user group record containing one or more group secrets is encrypted at an administrator using a user secret (e.g., a user ID and password combination) known to the administrator and to a communication device. The encrypted user group record is then distributed to the communication device where it is decrypted using the user secret.Type: GrantFiled: October 25, 2002Date of Patent: March 29, 2011Assignee: Pine Valley Investments, Inc.Inventors: Thomas Andrew Hengeveld, Dennis Michael Martinez

Patent number: 7599496Abstract: A method for distributing encryption keys for use in communication systems such as trunked radio communication systems. Group traffic keys are encrypted at a key administrator and passed to a distribution facility for storage and distribution. The distribution facility passes the encrypted group traffic key to communication devices where the group traffic keys are decrypted and used to encrypt/decrypt traffic.Type: GrantFiled: August 27, 2002Date of Patent: October 6, 2009Assignee: Pine Valley Investments, Inc.Inventors: Thomas Andrew Hengeveld, Dennis Michael Martinez
