The technology used for positioning a tracked mobile subscriber (eg. Assisted GPS).

Derivation:

Positioning Data IE (TS 49.031). The positioning technology can be derived by converting bits the five most significant bits (bits 8-4) into an integer. It needs to be noted that more than one positioning method may be recorded in the Positioning Data IE (TS 49.031). In order to identify the positioning technology actually used bits 3-1 which code the usage of the positioning technology need to be analysed.
