Abstract: A method for transferring state information pertaining to a plurality of SIP conversations from a first SIP server to a second SIP server, said first SIP server and said second SIP server being operatively connected to one or more SIP gateways, the method comprising at a controlling node: monitoring said first SIP server until ongoing transactions are terminated; after termination of said ongoing transactions, obtaining dialog state information pertaining to conversations managed by said first SIP server from said first SIP server; and storing said obtained dialog state information at said second SIP server.

Abstract: An apparatus (CEG) for interconnecting a user agent to a cluster of servers, the apparatus comprising a first protocol agent configured to exchange first messages with said user agent according to a SIP protocol, wherein said apparatus has the role of a User Agent Server; a second protocol agent configured to exchange second messages with a selected server from among said cluster of servers according to the SIP protocol, wherein said apparatus has the role of a User Agent Client; interconnection means for relaying messages from among said first messages and said second messages between said first protocol agent and said second protocol agent; wherein said second protocol agent is further configured to terminate elasticity control messages received from said cluster of servers.

Abstract: A method, in a wireless telecommunications network, for scheduling a push data transmission from the network to a user equipment (UE) device, including providing a push notification including a predefined parameter representing a delay period for the notification, determining a projected time for establishment of an active communications channel of a network interface of the UE, on the basis of the determination, linking transmission of the notification with transmission of data using the established active communications channel or transmitting the notification instantaneously.

Abstract: The invention concerns a method for transferring data from a sensor over a computer network, wherein the method comprises the steps of receiving from the sensor a signal representing a physical quantity, encoding the signal, converting the signal into a message, and transmitting the message over the computer network, wherein the conversion of the signal into the message comprises the step of generating the message by combining a first message header with a message body, wherein the first message header comprises the encoded signal and the message body comprises application data. The invention further concerns a device and computer program product therefore.
