1. An apparatus for receiving text messages in a network, said apparatus comprising:
- means for selecting a coding data set from a local coding data memory for decoding a received text message and, when the apparatus moves into a different network for communication, for selecting a coding data set from the local coding data memory as an initial default coding data set for the network, said initial default alphabet being the same for each different network;
means to receive and demodulate the received text message;
means to detect a type of the received text message;
means responsive to the received text message type to determine a coding data set which has been used to encode the received text message;
means for decoding the received text message with the determined coding data set; and
means for displaying the decoded message,wherein the means for selecting the coding data set from a local coding memory changes the initial default coding data set for the different network to the determined coding data set for subsequent use in the different network.

Abstract
A receiver for text messages in a network includes a means to receive and demodulate a signal. A message type detector determines whether or not the message is a text message. If it is, a header decoder looks at the header of the text message for encoding information. An alphabet selector then selects an appropriate decoding alphabet from an alphabet memory to be used by a message decoder prior to display the text message on a display.

4. A method for receiving text messages in a network, said method comprising the steps of:
-
detecting a movement into a different network for communication; selecting an initial default coding data set when the movement into the different network is detected, said initial default coding data set being the same for each different network; receiving and demodulating a message; detecting a type of the message received; determining a coding data set used to encode the received message; selecting the determined coding data set from a local coding data memory; decoding the message received; displaying the decoded message; and changing the initial default coding data set to said determined coding data set for subsequent use in the detected different network. - View Dependent Claims (5, 6)
