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