Supported X-Header Information
Out of all the configurable X-header information, some information requires SMF to send the corresponding values to the UPF. The following table lists the information that is sent from the SMF to the UPF for X-header insertion.
| Xheader Field | Description | Present in Session Establishment | Modified in Session Modification |
|---|---|---|---|
| String Constant | Inserts the configured string in xheader | — | — |
| Charging ID | Per Flow or Bearer Charging Id | Yes | — |
| IMEI | IMEI for the call | Yes | — |
| IMSI | IMSI for the call | Yes | — |
| Rat-Type | RAT type for the UE session | Yes | Yes |
| s-mcc-mnc | MCC or MNC of the SGW or AMF | Yes | — |
| Sgsn-address | AMF or SGW address | Yes | Yes |
| ULI | User Location Info | Yes | Yes |
| GGSN-Address | N4 or or S5 endpoint of SMF | Yes | Yes |
| Radius-station-ID | MSISDN of the UE | — | — |
| Sn-rulebase | Rulebase for a call | Yes | Yes |
| Subscriber-ip-address | IP address allocated to UE | — | — |
| Msisdn-no-cc | Obtained from MSISDN | Yes | No |
The subscriber-specific fields—IMSI, MSIDN, and IMEI—are encoded in the "User ID" standard IE. For more details, see 3GPP 29.244, Section 8.2.101.
Rest of the fields are sent in the "Subscriber Parameters" proprietary AVP. Some fields, such as the "Rulebase" and "UE IP address", are sent as a part of the created PDRs.
