Abstract

DC60 (12/11/42) Methods and systems for sending short data messages in a TDMA communication system in controlled stations.The selected TDMA frames are assigned to a message frame and one or more data channels from each frame of the message. Data can be encrypted and sent multiple times at higher power levels. From the control station To the transmitter / receiver Through good data channels in each text frame, a well-formatted TDMA frame is also a slow co-control channel frame, where alphanumeric text and short numbers can also be transmitted over a controlled channel that The broadcast power of a digital radio communication connection or another communication channel consisting of one or more channels from adjacent frames in the TDMA communication point, an increase in the transmission power is used in combination. With repeating Repeat to add The tolerance of the effective signal without the hassle of moving units. Extreme delay Or interference between channels where there is a need for greater signal tolerance. And when there is a need for longer messages or for voice messages, the message itself may be stored and the mobile unit will be notified of the message, method and system for sending short-data messages in the TDMA communication system in the station with the The selected TDMA frame control is assigned to a text frame and one or more data channels from each frame of the message are assigned to the sender / receiver.The data can be encoded and sent multiple times at high power levels. up From the control station To the transmitter / receiver Through good data channels in each text frame, a well-formatted TDMA frame is also a slow co-control channel frame, where alphanumeric text and short numbers can also be transmitted over a controlled channel that The broadcast power of a digital radio communication connection or another communication channel consisting of one or more channels from adjacent frames in the TDMA communication point, an increase in the transmission power is used in combination. With repeating Repeat to add The tolerance of the effective signal without the hassle of moving units, large delays. Or interference between channels where there is a need for greater signal tolerance. And when there is a need for longer messages or for voice messages, the message body may be stored and the mobile unit will be notified of the message.

Claims (1)

1. A method for sending short message service (SMS) data messages over a TDMA communication channel with a set of frames. Where each set of frames will include a number of frames. Where the subset of the frame One of these is the frame of the control channel to carry information of the control channel. Control the tolerance of the first signal where the methods include: - Encrypting the aforementioned SMS messages to create an encrypted message; And - Sending the said encrypted message through the channel.
