Patent ID: 7450664

Claim:
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.
