  • Patent number: 8576800
    Abstract: A system and method for providing connectivity between mobile devices and access points of a network without redundant solicitation of communication by the mobile device at each access point is described. The method involves receiving a data packet at a first access point in a control group; transmitting the data packet from the first access point to the mobile device; determining if the mobile device acknowledges receipt of the data packet; responsive to determining that the mobile device failed to acknowledge receipt of the data packet, forwarding the data packet to a second access point; and transmitting the data packet from the second access point to the mobile device.

  • Patent number: 6778509
    Abstract: An approach for minimizing response times in transporting traffic over a packet radio communication system is disclosed. A terminal transmits a packet resource request message that specifies user terminal information using a contention channel according to a prescribed protocol. A gateway station receives the packet resource request message and transmits an assignment message that specifies a channel assignment based upon the user terminal information, wherein the terminal is configured to transmit the packets over a channel is based on the channel assignment. This approach has particular applicability to a satellite communication system.

  • Patent number: 6650895
    Abstract: A system and a methodology to improve the end-user quality of service both in terms of response time and reliability for the transport of in-call DTMF signals in wireless systems, particularly in geostationary mobile satellite systems. The methodology encompasses several techniques to provide acceptable end-to-end quality of service for DTMF. A technique is applicable for transport of DTMF in the wireless subscriber to network direction, where DTMF digits are carried in the form of an out-band message. The central part of the technique is to allow multiple key presses in the same message, thereby increasing efficiency and throughput in long-delay environment. Another technique utilizes the vocoder's functionality to carry DTMF in-band, thereby reducing system complexity.
