1.5.2.2 Implementing input of Terminal data to SIM (direction TE to ME)
Case 1
Data will be packed to 7-bit.
Maximum text length: 160 characters
Example: "AB" ® 0x41,0x21
Case 2
Data will be saved without any conversion.
Maximum text length: 280 characters
Example: "4142" ® 0x41,0x42
Problems:
• "8f" ® Error (invalid GSM character)
Case 3
Two bytes are needed. No conversion.
Maximum text length: 280 characters
Example: "0041" ® 0x00,0x41
Problems:
• "41" ® Error (there are two bytes needed)
Case 4
Two bytes are needed. Two bytes will be converted to 1 byte GSM and 7-bit packed.
Maximum text length: 640 characters
Example: "00410042" ® 0x41,0x21
Problems:
• "41" ® Error (there are two bytes needed)
• "4142" ® Error (invalid character)
• "0000" ® Error (not an UCS2 character)
• "007B" ® 0x1B,0x28 (the saved data are two bytes long, not 1 byte like in all other cases.
This effects the maximum input length of a string)
Case 5
Two bytes are needed. Two bytes will be converted to 1 byte GSM.
Maximum text length: 560 characters
Example: "00410042" ® 0x41,0x42
Problems:
• "41" ® Error (there are two bytes needed)
• "4142" ® Error (invalid character)
• "0000" ® Error (not an UCS2 character)
• "007B" ® 0x1B,0x28 (the saved data are two bytes long, not 1 byte like in all other cases.
This effects the maximum input length of a string).
