An end user local network and a packet data communication network are interconnected by an arrangement including a packet data network backbone, at least one packet data node with a serving functionality for handling packet data communication, and a gateway functionality for providing communication with external network(s). At least one virtual distributed node provides a gateway functionality and includes an interworking node device including a converting device for converting between a local network and user communication protocol including a user level data packet format (ULC) and an internal packet data communication protocol using an internal packet data format (ICP). The virtual distributed node includes a management functionality (MA) for managing the interworking node device. The management functionality is executed in a packet data node, and the packet data network backbone is used for communication.

Arrangement and method relating to packet data communication and a packet data communication system

In a cellular communication system, a processing arrangement and method supporting packet data communication. The processing arrangement includes a plurality of base station processors (BPs) and a plurality of managing processors (MPs). Each BP communicates with a plurality of base stations and mobile subscriber stations. The MPs manage the mobile subscriber stations, and each MP contains mobile subscriber station information for a number of mobile subscriber stations. The MPs provide information regarding their processing load status to the BPs by adding the information to packet data transmissions. The BPs use the information to assign each mobile subscriber station that is registered with the arrangement to one of the MPs.

Arrangement, a system and a method relating to a packet data communication

An arrangement, a system and a method distribute messages in a communication system supporting communication of packet data. The arrangement includes a number of processors communicating with each other. Each processor is connected to all other processors via at least two physically separate networks. For each processor, information holding devices are provided for keeping information about all communication paths to all other processors. For obtaining information, first messages are sent from each processor to all other processors using all of the at least two networks.
