Section: 16.4 List of RADIUS attributes
Content: The following tables describe the actual content of the RADIUS messages exchanged between the GGSN/P-GW and the AAA server. Other RADIUS attributes may be used as defined in RADIUS RFC(s). Unless otherwise stated, when the encoding scheme of an attribute is specified as UTF-8 encoding, this shall be interpreted as UTF-8 hexadecimal encoding. NOTE: Any digit is converted into UTF-8 character. For example, digit 5 is converted to UTF-8 character ‘5’, which in hexadecimal representation has a value 0x35. Similarly, a hexadecimal digit F is converted to either UTF-8 character ‘F’, which in hexadecimal representation has a value 0x46, or to UTF-8 character ‘f’, which in hexadecimal representation has a value 0x66.
