Abstract: The present invention relates to a first node and a second node in a mobile telecommunication network. The network comprises a first node, a second node and a third node, wherein the first node is connectable to the second node and the second node is connectable to the first node and to the third node and the third node is connectable to the second node. A system function is realized by the execution of a master-process implemented in the first node and a slave-process implemented in the third node, wherein the execution of the master-process realizes a control function associated with the system function. The master-process of the first node is adapted to temporarily delegate the responsibility to realize the control function to a master-proxy-process implemented in the second node and the master-proxy-process implemented in the second node is adapted to take over the responsibility to realize the control function from the master-process of the first node.

Abstract: A method is described for associating a data packet (DP) with a packet bearer (PB) in a user equipment (UE1) of a communication network. The data packet is sent in a data flow from an application function of the user equipment, the packet bearer (PB) is established with the user equipment to transmit the data packet (DP) over the communication network towards a further entity, and the user equipment is adapted to establish different packet bearers. The method comprises the steps of identifying the flow with the data packet in a control entity of the communication network, determining the packet bearer for association with said flow from the different packet bearers in a policy function of the control entity, determining a routing level identification of the further entity, instructing the user equipment to install a packet filter based on the routing level identification, wherein the packet filter associates data packets comprising the routing level identification of the further entity with the determined packet bearer, providing the routing level identification to the application function, including the routing level identification into the data packet, and forwarding the data packet (DP) on the determined packet bearer (PB). A corresponding network, control entity, monitoring entity and computer program are also described.

Abstract: In the present invention, the implementation of a protocol that embeds packe ts is made sensitive to the type of data being embedde, so that adjustable parameters can be set automatically at the layer providin g the parameters being adjusted in accordance with the packets being embedded. Thus it is taken into account that the data in packets being received from a higher layer in order to be encapsulated or segmented and sent further (either directly into the link or on to lower layer), may be classified into different categories with respect to the adjustable parameters, where the parameters can automatically be adjusted fo r an individual packet in accordance with the category into which is classified.

Abstract: A method of processing a data unit of a first protocol layer (L3) for transmission in a data unit based communication system is described, comprising the steps of passing to a second protocol layer (L2) a given data unit of said first protocol layer (L3) that is to be transmitted, said second protocol layer (L2) lying below said first protocol layer (L3), determining a numeric value of a numerically quantifiable parameter associated with said given data unit of said first protocol layer (L3), embedding said given data unit of said first protocol layer (L3) into one or more data units of said second protocol layer (L2), performing transmission control for said one or more data units of said second protocol layer (L2) that embed said given data unit of said first protocol layer (L3), where said embedding and/or said transmission control is performed in accordance with said numeric value of said numerically quantifiable parameter.

Abstract: A method of controlling the flow of an amount of data from a sending peer to a receiving peer of a predetermined communication protocol is described. The method comprises dividing the amount of data into a plurality of data segments, where the data segments are ordered in a sequence. The segments are sent to the receiving peer in the order of said sequence. The receiving peer acknowledges the correct receipt of a data segment and identifies the last correctly received data segment of the sequence that was received in the proper order of the sequence. The sending peer is arranged such that if it receives a threshold number of duplicate acknowledgements, it performs a retransmission. The threshold number that trigger a retransmission is an adaptive parameter determined based on the size of a receive window, the size of the receive window representing a number of data segments which can be stored in a buffer space at the receiving peer.

Abstract: A method and an apparatus for transmitting error-tolerant data is disclosed employing the ARQ technique, wherein the retransmission of erroneous data is performed up to the point where the remaining amount of errors is acceptable (for instance because the erorrs will not be perceived by the recipient of the information, which can be a person or a higher level protocol with additional error correction capabilities). The number of data blocks (RLC) detected as erroneous is employed to define a reliability measure (RM) and a request for retransmission of the erroneous data blocks is performed until a desired reliability threshold (RT) is reached. An additional threshold with a higher value than the first one can be employed to request for optional retransmission when the reliability measure (RM) is between the first and the second threshold. The retransmission will be performed only if further conditions such as channel availability are met.
