    Abstract: The Packet Control Function (PCF) has limited knowledge about the nature of the packet data arriving on a bearer path connected via the Packet Data Serving Node (PDSN), and cannot make an intelligent decision on its own as to how best to handle the packet data. Thus, the PDSN provides bearer-specific information by classifying the priority of received packet data; encapsulating the packet data within the payload of a Generic Routing Encapsulation (GRE) frame; and for high priority packet data i) setting a protocol type field in the header of the GRE frame indicating said packet includes an attribute field; and ii) adding an attribute field to the payload of the GRE packet which provides an indication of said high priority data. Furthermore, the PCF can send an A-11 request to the PDSN indicating the features that the PCF is requesting the PDSN enable. For example, for a short data indication, the PCF would request the PDSN enable adding the attribute field to the GRE frame when an Short Data Burst (SDB) is suitable.

    Abstract: A method and system for achieving a link budget improvement in a diverse OFDM radio system by addressing the timing misalignment issue that can occur due to the differences in propagation time in signals between mobile stations and Radio Access Nodes. Timing misalignment is shared or split between the primary path to a primary Radio Access Node and a diverse path to a diverse Radio Access Node. The relative timing offsets between mobile stations are adjusted, the mobile stations are grouped into zones using a variety of different grouping techniques, and the transmission for each mobile station is scheduled, using one or more of a variety of scheduling techniques.

    Abstract: A method, apparatus, and computer instructions for managing push-to-talk communications. Different types of PTT calls with a variety of protocol configurations are supported with the use of PTT Type and Protocol Type fields in a call set up control message. When a push-to-media indicator in a call set up request message is detected in a radio access network in a communications system, the packet is directed to a push-to-media gateway in a packet data network in the communications system. The push-to-media packet is processed using the push-to-media gateway to manage the push-to-media call. This directing of the packet reduces the latency in managing a push-to-media call.

    Abstract: A dual microphone communication device comprising a first microphone module, a second microphone module and a mixer circuit is provided. The first microphone module amplifies a near-end audio signal to produce a first audio signal. The second microphone module receives and amplifies the near-end audio signal by a fixed gain and a constant phase difference to produce a second audio signal. The mixer circuit subtracts the second audio signal from the first audio signal to produce a third audio signal so that interference resulting from echoes is significantly reduced while keeping, or enhance the near end voice level.

    Abstract: A method and system for coordinated interference suppression in a communication system. The communication system implements at least a first radio access technology via a first base station and a second radio access technology via a second base station. The first and second radio access technologies differ from one another. Information relating to an interference signal received at the first base station via the first radio access technology is received at the second base station from a first device associated with the first base station. At a second device associated with the second base station, an interfering user equipment accessing the second base station via the second radio access technology is identified. The identification is based on the information received from the first device associated with the first base station. Interference caused by the identified interfering user equipment is suppressed by the second base station.

    Abstract: The invention provides methods and systems for extending RSVP signaling to wireless networks. RSVP messages may be intercepted by an RSVP daemon, adjusted as necessary to accommodate the wireless network, and then forwarded on as RSVP messages either on a traffic channel or as a short data burst. Alternatively, the RSVP messages may be encapsulated in layer 3 messages. Alternatively, RSVP messages may be intercepted by another component, such as a PDSN, which then coordinates the establishment of the requested wireless connection.
