PCT No. PCT/FI95/00024 Sec. 371 Date Jul. 16, 1996 Sec. 102(e) Date Jul. 16, 1996 PCT Filed Jan. 20, 1995 PCT Pub. No. WO95/20283 PCT Pub. Date Jul. 27, 1995For packet data transmission between fixed network elements, such as a mobile exchange, a base station controller and base stations, in a mobile communication system, 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 between them for transmitting data packets. Only a processing 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 the packet data processing, instead of normal signalling message handling. |
