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: An arrangement, system, and method for switching data packet flows in a communication system. A flow processing core classifies packet flows and defines processing flow sequences applicable to the packet flows. A distributing arrangement directs the packet flows to appropriate functional units or processors according to each packet flow's applicable processing flow sequence. The current position of each packet flow in its respective processing flow sequence is indicated. Packet flow sequence information may be determined so that reclassification of already classified packets is avoided.

Abstract: A wireless communication network manages communication resources based on the types of packet data being carried by the network for each mobile station. Packet data for each use is matched to packet matching filters in defined flow type profiles. Each flow type profile corresponds to an expected application behavior and includes one or more resource control parameters having values set with regard to that expected behavior. An application activity profile is generated for each mobile station based on deriving resource control parameters using parameter values corresponding to the active flows for each mobile station. The network determines each mobile station's active flows based on matching that mobile station's packet data types to one or more of the defined flow type profiles. Thus, the network manages communication resources individually and/or jointly for its users based on the type of packet data traffic passing through the network for each of those users.

Abstract: An method for PDSN (Packet Data Serving Node) initial assignment and re-selection in a wireless communication system is provided. The method is implemented in PCF (Packet Control Function) within a third-generation (3G) CDMA Radio Access Network (RAN). The methodology reduces the number of point-to-point (PPP) re-establishments, when a Mobile Station (MS) roams to a different packet zone/PCF. The method generates a table of PDSN identification numbers cross-referenced to the PDSN Internet protocol (IP) addresses, residing with each PCF. A PDSN Id number is selected from the table using the MS IMSI (International Mobile Station Identifier) as a key to perform the selection. The present invention methodology addresses the issue of forward and backward compatibility, scalability, reliability, and load sharing in the PDSN selection.
