摘要:
In a communication system (SYS) in which a packet data transfer is performed between the network side (NS) and the subscriber terminal side (SS) a physical connection (LC) is maintained during the data packet transfer. An active period detector (AP-DET) detects an active period of data packet generation by evaluating the inter-arrival time (TDIFF) between successively arriving data packets (DP). If the inter-arrival time (TDIFF) falls within a predetermined range a physical connection maintaining device (LC-MAIN) maintains the physical connection (LC) even if a transmitter queue (TR-QUE) temporarily becomes empty. Therefore, within the active period (AP) the transmitter (NS-TR; SS-TR) indicates a non-empty queue. The invention finds particular application in the GPRS/(E)GPRS/GSM environment.

For improving feed-based automatic distribution of content to a mobile terminal via a mobile network, a network component (150) comprises a network-side agent (160). The network-side agent (160) manages the feed-based automatic transmission of content to the mobile terminal and is configured to periodically generate a feed request to a feed server, to receive a requested feed from the feed server in response to the feed request, and to transmit the received feed to the mobile terminal. The network component (150) may also comprise a cache memory (164) for storing copies of feeds and contents and a proxy for processing feed requests and content requests received from the mobile terminal (110).

A mobile ambient network (MAN) negotiator 106 is provided for negotiating with ambient access networks (AANs) 102 on behalf of a MAN 104 to select a particular AAN to handle a wireless communication session for the MAN. The MAN is, e.g., either a user terminal (UT) or a private area network (PAN). The negotiations performed by the MAN negotiator on behalf of the MAN include establishing a secure, trusted relationship between the MAN and the AAN, as well as negotiating costs, billing arrangements and the like. The MAN negotiator communicates with the MAN via a dedicated wireless communication channel but preferably communicates with the AANs via non-wireless, i.e. fixed, connections.
摘要:
A method is described for registering a node of an underlying network at an overlay network, characterized in that the node of the underlying network registers at a registration node which initiates a propagation of registration information towards the overlay network.
摘要:
Delays associated with real-time, interactive communications are reduced. A communications device A engages in a real-time, interactive communication with a communication device B. User A provides digital content to be transmitted to device B. A real-time, interactive connection is established between A and B which takes a certain delay time. That delay time is compensated for so that user B receives A's digital content and can respond to it faster than B could without the delay time compensation. This faster response by the B to A's communication enhances the interactive, real time, conversational feel of their communication.
