    • A method and system for maintaining a connection between two hosts in a multi-hop network comprising at least one network node disposed between the two hosts and a network element, e.g., a NAT, designed to release the connection after a period of inactivity. The method includes determining a first node in which a keep-alive message will terminate after crossing a network element designed to release the connection after a period of inactivity, and sending a keep-alive data packet configured to terminate in the first node after crossing the network element designed to release the connection. The keep-alive packet configured to terminate in the first node after crossing the network element designed to release the connection may be sent within a time period less than the time period of inactivity after which the network element would release the connection. The method allows for a connection to be kept open without waking up a client device and/or without activating air interface procedures.
    • 一种用于维护多跳网络中的两个主机之间的连接的方法和系统,包括设置在两个主机之间的至少一个网络节点和被设计为在不活动时段之后释放连接的网络元件(例如,NAT)。 该方法包括:确定第一节点,其中保持活动消息将在经过设计为在不活动时段之后释放连接的网络元件之后终止,以及发送保持活动数据分组,其被配置为在跨越所述第一节点之后终止于第一节点 网元设计用于释放连接。 配置成在穿过被设计为释放连接的网络元件之后终止于第一节点的保持活动分组可以在小于网络元件将释放连接的不活动时间段的时间段内发送。 该方法允许连接保持打开而不唤醒客户端设备和/或不激活空中接口程序。

    • The present invention relates to an arrangement and a method for flow control of data packets in a communications system supporting communication of packet data. The arrangement comprises classifying means (1) for, by means of a number of parameters defining a number of data packet subflows, whereby each received packet belongs to one of the subflows. For each received data packet, an individual packet holding time is given by the size of the data packet and by the (desired) bandwidth of the subflow to which the packet belongs. It further comprises first queueing means (2) comprising one subflow queue (SFQ) for each subflow, such that received data packets are placed in the appropriate subflow queue, and one or more second queueing means (3), each comprising a circular timeslot array register, wherein for each timeslot a timeslot queue (TSQ) is provided. Data packets from the subflow queues are placed in the appropriate time slot queues in relation to a current time slot queue, the packets in which, if any, currently being output, such that the data packet holding times can be observed.
    • 本发明涉及支持分组数据通信的通信系统中的数据分组的流量控制的装置和方法。 该装置包括分类装置(1),用于通过定义多个数据分组子流的多个参数,由此每个接收分组属于其中一个子流。 对于每个接收的数据分组,单个分组保持时间由数据分组的大小和分组所属的子流的(期望的)带宽给出。 它还包括第一排队装置(2),其包括用于每个子流的一个子流队列(SFQ),使得接收的数据分组被放置在适当的子流队列中,以及一个或多个第二排队装置(3),每个包括圆形时隙阵列 寄存器,其中对于每个时隙,提供时隙队列(TSQ)。 来自子流队列的数据分组被放置在与当前时隙队列相关的适当的时隙队列中,即当前正在输出的分组(如果有的话),使得可以观察到数据分组保持时间。
