11.3.2.10.1 SGSN LAC,RAC,MCC,MNC Representation
The lac, rac and mcc are represented as single long number in the response, but the actually
represent a hierarchy of codes. The logic to derive different codes from a single long number( of
8 bytes) is given below:
Byte Pos
8
Byte Pos
7
Byte Pos
6
Byte Pos
5
Byte Pos
4
Byte Pos
3
Byte Pos
2
Byte Pos
1
Method to derive rac, lac, mcc, mnc from a number in racList
Byte Position 1 – rac
Byte Position 3 and 2 together – lac
Byte Position 5 and 4 together – mnc
Byte Position 7 and 6 together – mcc
Byte Position 8 – unused
Method to derive lac, mcc, mnc from a number in lacList
Byte Position 2 & 1 – lac
Byte Position 4 and 3 together – mnc
Byte Position 6 and 5 together – mcc
Byte Position 8 and 7 – unused
Method to derive mcc, mnc from a number in mnclist
Byte Position 2 & 1 – mnc
Byte Position 4 and 3 together – mcc
Byte Position 8 to 5 – unused
Example:
A number 1090720953797377 in racList actually means the following codes
Mobile Country Code: 992
Mobile Network Code: 323
Location Area Code : 11
Routing Area Code : 1
