<p>The invention relates to a method for packet data transmission between fixed network elements, such as a mobile exchange (MSC), a base station controller (BSC) and base stations (BTS), in a mobile communication system, and to fixed network elements of a mobile communication system applying such a method. A node-to-node packet data transmission in a digital mobile communication network is carried out by using network elements as packet nodes and by utilizing existing signalling protocols (LAPD, MTP) between them for transmitting data packets. Only a processing (36, 37, 64) of incoming and outgoing data packets is introduced into the network elements. The normal signalling messages of a mobile communication network used for packet data transmission are only provided with a new identifier indicating that the message contains packet data, so that the packet data messages can be forwarded to said packet data processing, instead of normal signalling message handling.</p> |
