This feature enables the SaMOG Gateway to receive the last known LTE location of the subscriber in the 3GPP-User-Location-Info AVP from the Diameter-based AAA server over the STa interface. This information is then used by SaMOG in the Create Session Request (CSR) messages over the S2a interface. The 3GPP-User-Location-Info AVP is received by SaMOG when the aaa-custom23 dictionary is available.
With the 3GPP-User-Location-Info AVP, SaMOG can then:
Use the PLMN values (MCC/MNC) in the Serving-Network IE in the CSR messages.
Populate the User-Location-Information (ULI) IE in the CSR messages.
The aaa-custom23 dictionary is customer specific. For more information, contact your Cisco account representative.
