Method for transmitting data packets according to a packet data service in a cellular mobile radio network provided for voice and data transmission

Abstract

In order to transmit data packets for a packet data service in a cellular mobile radio network, in each case one channel (TCH) in the radio transmission system (BSS) of the mobile radio network is reserved and linked to a transmission channel (NUC), which leads to a separate service network node (GSN), to form a continuous data channel. Data packets and signalling information are transmitted jointly via the data channel in a single data protocol between the mobile subscriber station (MS) and the service network node (GSN). In this way, signalling information and data packets are transmitted in only one protocol, to be precise the data protocol. By using only the data protocol for the joint transmission of the data packets and signalling information, there is a reduction in the signalling load and the channel seizure duration in the mobile radio network in comparison with the solution with two separate protocols for signalling and data.
