C.2 GPRS Support Nodes

This clause defines a naming convention for GSNs.

It shall be possible to refer to a GSN by a logical name which shall then be translated into a physical IP address. This clause proposes a GSN naming convention which would make it possible for an internal GPRS DNS server to make the translation.

An example of how a logical name of an SGSN could appear is:
sgsnXXXX.mncYYY.mccZZZ.gprs

X, shall be Hex coded digits, Y andZz shall be encoded as single digits (in the range 0-9).

If there are less than 4 significant digits in XXXX one or more "0" digit(s) is/are inserted at the left side to fill the 4 digits coding. If there are only 2 significant digits in YYY, a "0" digit is inserted at the left side to fill the 3 digit coding.

As an example, the logical name for SGSN 1B34, MCC 167 and MNC 92 will be coded in the DNS server as:
sgsn1B34. mnc092.mcc167.gprs
