    • 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.

    • 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.
    • 一种用于管理即按即说通信的方法,装置和计算机指令。 在呼叫建立控制消息中使用PTT类型和协议类型字段来支持具有各种协议配置的不同类型的PTT呼叫。 当在通信系统中的无线电接入网络中检测到呼叫建立请求消息中的按压媒体指示符时,该分组被定向到通信系统中的分组数据网络中的按压媒体网关。 使用推送到媒体网关处理推送到媒体的数据包来管理推送媒体呼叫。 分组的这种引导减少了管理推送媒体呼叫的延迟。

    • 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.
