3GPP-User-Location-Info AVP

The 3GPP-User-Location-Info AVP (type 22) is defined in section 16.4.7.2, Coding 3GPP Vendor-Specific RADIUS attributes within the 3GPP TS29.061, Interworking between the Public Land Mobile Network (PLMN) specification. This AVP supports packet based services and Packet Data Networks (PDN).

3GPP-User-Location-Info contains the location type, for example a cell global identifier (CGI), and actual location data for the specified cell.

The SBC supports this attribute. It occurs in AAA messages received by the P-CSCF.

The AVP consists of four fields:

• The 1-octet 3GPP-type field contains the value 22.
• The 1-octet 3GPP-length field contains the attribute length in octets.
• The 1-octet Geographic Location Type field identifies the equipment type whose location is being provided.
• The variable length Geographic Location field contains the geographic coordinates of the equipment specified in the Geographic Location Type field.

This AVP contains the location type, for example a cell global identifier (CGI), and the actual location data for the specified cell.

  0 = CGI
  1 = SAI
  2 = RAI
128 = TAI
129 = ECGI
130 = TAI and ECGI
135 = NCGI
136 = 5GS TAI
137 - 5GS TAI and NCGI

Other values are reserved for future use.
