Abstract

The basic idea is to enable a user interacting without influencing the active IP (Internet Protocol) services on signaling level over GPRS (General Packet Radio Service) signaling level. This enables the user to send GPRS signals via the mobile network press button like DTMF (Dual Tone Multiple Frequency) over the GPRS layer. For an active GPRS session it may be used to request more or less bandwidth for the active session.By pressing a function button on the mobile handset, the user enables the sending of a GPRS signal for the UE (User Equipment) towards the mobile network. First, it is necessary to differentiate between active already existing GPRS sessions with existing PDP (Packet Data Protocol) context and inactive GPRS sessions. Before an activated GPRS session, GPRS signals use the GPRS signaling bearer. During active GPRS sessions, the GPRS signal uses the information from the active GPRS sessions and again the signals are sent over GPRS signaling layer. The messages to be sent across the air interface uses the frame stealing mode of transmission. While being sent across the air interface, the messages should contain the following information:

This enables the user to send GPRS signals via the mobile network press button like DTMF (Dual Tone Multiple Frequency) over the GPRS layer.

Before an activated GPRS session, GPRS signals use the GPRS signaling bearer. During active GPRS sessions, the GPRS signal uses the information from the active GPRS sessions and again the signals are sent over GPRS signaling layer.

The messages to be sent across the air interface uses the frame stealing mode of transmission.

While being sent across the air interface, the messages should contain the following information:

a) START GPRS-SIG: Containing the digit value (0-9,A,B,C,D,*,#) or predefined service related function keys;

b) START GPRS_SIG ACKNOWLEDGE: Containing the digit value (0-9,A,B,C,D,*,#) or predefined service related function keys. The digit value are corresponding to the DTMF tone that the network applies towards the remote user;

c) STOP GPRS-SIG: No further info;

d) STOP GPRS-SIG...
