    • The present invention relates to a method and an arrangement to maintain a TCP connection (230) between two hosts (140, 250) in a multi-hop network (110,120). If the connection (230) is inactive (no IP packets sent or received) during a certain period of time, it may happen that the connection (230) is released by certain intermediate network entities such as a Network Address Translation NAT function (130). The current invention overcomes this problem by sending keep-alive packets (210) from one of the hosts (250) towards the other (140) at regular intervals. Said packets (210) prevent the NAT (130) from releasing the connection (230). In order to not disturb the other host (140) e.g. a mobile terminal in a sleeping mode, the keep-alive packets (210) are adapted in such way that they are sent far enough to reach the NAT (130) but not all way to the other host (140).
    • 本发明涉及一种在多跳网络(110,120)中维护两个主机(140,250)之间的TCP连接(230)的方法和装置。 如果连接(230)在一段时间内不起作用(没有IP分组被发送或接收),则可能发生连接(230)由诸如网络地址转换NAT功能(130)的某些中间网络实体释放, 。 本发明通过以规则的间隔向另一个(140)发送保持活动分组(210)来克服这个问题。 所述分组(210)防止NAT(130)释放连接(230)。 为了不打扰另一主机(140),例如 在休眠模式下的移动终端,保持活动分组(210)被调整成使得它们被发送得足够远以到达NAT(130)但不是全部到达另一个主机(140)。

    • A method is provided for verifying an engine torque estimation and includes estimating the engine torque based on the amount of fuel injected into the engine, where the engine torque is obtained from a fuel injection table, estimating a first vehicle weight value by a calculation based on acceleration of the vehicle and the estimated engine torque, estimating an auxiliary brake torque by using an auxiliary brake table, estimating a second vehicle weight value by a calculation based on the estimated auxiliary brake torque, and comparing the first vehicle weight value with the second vehicle weight value.

    • A method for controlling a cruise control operable to maintain a set speed of a vehicle according to a plurality of goal droop curves is provided. The goal droop curves include: an isochronous droop curve; a top droop curve; and a bottom droop curve. The method includes performing command according to the droop curves; registering that the vehicle soon will enter an uphill slope; estimating in a vehicle position before entering the uphill slope if a downshift in a transmission of the vehicle will occur when traveling the uphill slope during a coming time period (testimation); if the downshift is estimated to occur then performing a fuel saving action during the time period in order to avoid the downshift. The fuel saving action is one of an adaptation of transmission downshifting limits or to during the time period performing command according to a second isochronous curve.

    • The described messaging arrangement for delivering communication messages to recipients in a communication system comprises a number of messaging servers (201-204), a common message store (205) and a dispatcher (206). The messaging servers (201-204) are able to receive a message destined to a recipient, to store the message in the common message store and to inform the dispatcher of the received message that has been stored in the common message store. The dispatcher is then arranged to decide which messaging server to invoke for delivery of the message to the recipient. This decision could be made based on delivery preferences of the recipient. Thereafter, the dispatcher invokes the messaging server that has been decided to deliver the message, and the decided messaging server retrieves and delivers the message to the recipient. If necessary, the decided messaging server adapts the message to a message type handled by the decided messaging server. By this solution, a recipient could receive the message in any preferred message type, regardless of originating message type. Also, this arrangement makes it easier for an operator to integrate new messaging technologies handling new message types in the system.
    • 用于向通信系统中的接收者传递通信消息的描述的消息传送装置包括多个消息收发服务器(201-204),公共消息存储(205)和调度器(206)。 消息传送服务器(201-204)能够接收去往接收者的消息,将消息存储在公共消息存储器中,并且向调度员通知已经存储在公共消息存储器中的接收消息。 然后,调度器被安排成决定哪个消息服务器被调用以将消息传递给接收者。 该决定可以基于接收者的递送偏好来进行。 此后,调度器调用已经决定传递消息的消息传送服务器,并且所确定的消息收发服务器检索并将消息传递给接收者。 如果需要,所确定的消息传送服务器将消息适配到由所决定的消息传送服务器处理的消息类型。 通过该解决方案,收件人可以以任何优先消息类型接收消息,而不管始发消息类型。 此外,这种安排使得操作者更容易将处理新的消息类型的新消息传递技术整合到系统中。
