Methods executed in a server in a communication network are provided. The server handles messages for at least one client and/or application. The method includes identifying deterioration in a connectivity or reachability between the server and the at least one client and/or application; and transmitting a re-establishment message to the at least one client and/or application. The message makes or enables the at least one client and/or application reestablish the connectivity or reachability. Related devices are also provided herein.

A method and a vehicle transmission for selecting a starting gear in a vehicle are provided, the method including steps of measuring a starting gear selection parameter, and selecting a starting gear for the next coming vehicle take-off in dependence of the measured starting gear selection parameter, wherein the starting gear selection parameter is the number of vehicle take offs per time unit. Additionally the parameter can be acceleration in movement of an accelerator pedal being depressed by a driver, accelerator pedal position and clutch wear. Benefits are increased clutch endurance for a vehicle that during at least a period has to perform frequent take-offs and at the same time enhancing take-off comfort for a vehicle that during at least a period goes long-distance.

An engine driven vehicle includes at least one engine, and control devices that are arranged to control a transmission that is driven by the engine. The control devices are arranged to receive at least two sets of data, each set comprising at least one of a first signal that comprises information about the gradient of the surface on which the vehicle is being driven sent from a first sensor, and at least one second signal that comprises information about the vehicle's speed sent from a second sensor, and at least one third signal that comprises information about the vehicle's acceleration. The invention is characterized in that the control devices are also arranged to calculate at least one of two different resistance to travel constants k1 and k2, in response to the first, second and third signals, and to control the transmission in response to at least one of the constants k1 and k2.

A method and Domain Name System (DNS) server for establishing a communication session in an Internet Protocol (IP)-based communication network. The DNS server receives a query containing a DNS name of a destination terminal as a search key, and determines whether an IP address for the DNS name is registered with the DNS server. If so, the DNS server returns the registered IP address to the sender of the query. If not, the DNS server sends a wake-up message to the destination terminal which, in response, establishes an IP data session with the communication network. The DNS server then receives an IP address for the destination terminal from an access server or from a Dynamic Host Control Protocol (DHCP) server, and returns the received IP address to the sender of the query.

The invention relates to a low latency transport of an Internet message over a connection from an Internet message-sending node to an Internet Message-receiving node. Said Internet Message-sending node determines the size of the Internet message (40) and compares the size of with a pre-determined single-packet threshold (42). Thereafter, the Internet Message-sending node performs a TCP Internet message-transport (44) over said connection if the size of the Internet message is larger than said single-packet threshold, and a single-packet (UDP) Internet message-transport (45, 46) if the size of the Internet message is smaller than said single-packet threshold

Vehicle (A) with an internal combustion engine (1), an automated transmission (2) coupled to the engine, and electronic control elements (3) which control the supply of fuel to the engine combustion chambers and recirculation of exhaust from the engine exhaust side (7) to its intake side (6). The control elements are disposed to compute, while the vehicle is moving, future driving resistance and the time until a future shifting between gears and to control valve elements (9) which regulate exhaust return flow during this time to optimize fuel consumption and emissions, when the gearshifting takes place.

The present invention relates to a system, a Midcom Agent, a method for re-establishing context and a computer program product for performing the steps of said method. In a multi-domain, multi-access IP network there is a need for a method to re-establish context associated with a flow when the end-to-end path changes. The path change is typically due to mobility, but can also be caused by access re-selection (which can be performed for a stationary mobile node as well). Therefore, a method is provided in which the context is moved from one middlebox to at least one selected middlebox via a Midcom Agent. An advantage with the present invention is that it facilitates the transfer of context information from a set of middleboxes to another set of middleboxes. Each set may contain diverse types of such middleboxes.
摘要:
Method and arrangement for providing a vehicle having an internal combustion engine and a drivetrain coupled to the internal combustion engine. A control unit is utilized for automatic gear selection, based on a function of the current rotational speed of an input shaft to the gearbox, and in which the control unit is designed to assume a first operating mode having a first working speed range with a first lower limit for downshifting to a gear with a higher transmission ratio.
