Retrieve User ID data from NASREQ AAA response

[javiermtorres]

erGW-AAA version

3.6 and 4.0

Erlang/OTP version

OTP 23

Description

• Motivation
  During authentication in a NASREQ dialogue, core user ID information (IMEI, MSISDN, IMEI) is sometimes available to the Diameter server that a NAS uses. This information can be included in the AAA response and handled by the NAS.
• Proposal
  If available, the following information will be sent:
  • IMSI: 3GPP-IMSI, from diameter_3gpp_base
  • MSISDN: Calling-Station-Id, from diameter_rfc4005_nasreq
  • IMEI: 3GPP-IMEISV, from diameter_3gpp_base

Current behavior

The 3GPP AVPs are not currently present in the AAA response, although Calling-Sttion-Id is.

Expected behavior

If available to the Diameter server, these AVPs will be present in the AAA response.

Config

No optional configuration is needed.
