3GPP-User-Location-Info Attribute

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

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

This attribute is supported by this implementation. It occurs in AAR and RAR 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 3GPP-User-Location-Info Attribute (sub-attribute number 22) is defined in section 16.4.7.2, Coding 3GPP Vendor-Specific RADIUS attributes, of 3GPP TS29.061, Interworking between the Public Land Mobile Network (PLMN) supporting packet based services and Packet Data Networks (PDN). 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

Other values are reserved for future use.

The variable length Geographic Location field contains the geographic coordinates of the equipment specified in the Geographic Location Type field.
