CauseFor
RecordClosing

Yes

Yes

V1/V2: Byte length 1

ASN.1:Integer

Reason why the CDR is closed. The valid values for this field are:

• 0 indicates user logged out, lost service, NAS request, callback, or host request.
• 1 indicates partial CDR volume threshold exceeded.
• 2 indicates partial CDR time threshold exceeded.
• 7 indicates user’s session was lost, session timeout, port error, NAS error, NAS reboot, port unneeded, port preempted, port suspended, service unavailable, user error, or idle timeout.
• 16 indicates Acct-Input/Output-Gigawords counter value has incremented. User has transferred over 232 bytes.
• 20 indicates a management action caused session termination.

ChargingType

Yes

Yes

V1/V2: Byte length 1

ASN.1:Integer

Always 8 (normal postpaid record).

Connection
Type

No

Yes

Integer

Identifies the type of connection.

• 0 indicates direct
• 7 indicates GGSN

ChargeableUid
Type

No

Yes

V1/V2: Byte length 1

ASN.1:
Integer

Field specifies the used type of ChargeableUid (Charging Type identifier).

Charging Type identifiers are initially assigned as follows:

• 00—reserved
• 01—IMSI (example: 1231231231244…)
• 02—NAI (example: foo@bar.com)
• 03—E.164 (a MSISDN - example: +358405627015)
• 04—TMPID (as described in 3GPP TS33.234 Temporary Identity Generation example)

The choice of the identifier (IMSI, NAI, or MSISDN) is determined by the value set for ChargeableUserIdInResponse in the simauth.aut file. If more than one value is set, the identifier returned by the NAS is used. Usually, the identifier returned by the NAS is the first in the list of multiple identifiers specified for ChargeableUserIdInResponse in the simauth.aut file.

For more information, see ChargeableUserIdIn Response in Table 189.

Also see ChargeableUid Length and ChargeableUid in this table.

DomainIndex

Yes

Yes

V1/V2: Byte length 1

ASN.1:
Integer

Location where the domain part starts in the Username and domain field.

V2: Valid only if the Charging Type Identifier value is 2 (NAI).

ChargeableUid

No

Yes

V1/V2: Integer length 1

ASN.1:
UTF8String

Replaces User Name field in Version 1.

GSMA-specified chargeable user with ChargeableUid
Type and with ChargeableUid
Length. The content string interpretation is based on the ChargeableUidType. (It is the value of the IMSI, NAI, or MSISDN.)

The choice of the identifier (IMSI, NAI, or MSISDN) is determined by the value set for ChargeableUserIdInResponse in the simauth.aut file. If more than one value is set, the identifier returned by the NAS is used. Usually, the identifier returned by the NAS is the first in the list of multiple identifiers specified for ChargeableUserIdInResponse in the simauth.aut file.

If the NAS fails to return a CUID, the value set for DefaultCUIDType in the cdracct.acc file is used.

For more information, see ChargeableUserIdIn Response in Table 189.

Also see ChargeableUidLength and ChargeableUidType in this table.

LocationInfo

Yes

Yes

V1/V2: Text length 64

ASN.1:
String

Location-Information attribute:

• The ISO 3166 country code is mandatory.
• The location identifies the network (“what” is code 3).

  • A1—State, region, province, or prefecture
  • A2—County, parish, gun (Korean county), or district
  • A3—City or township
  • NAM—Name (residence, business or office occupant)
• Additional location information fields may be defined according to bilateral agreements between operators. The contents are copied directly from the GSMA Vendor-Specific Location-Info attribute received from NAS. Strings may be truncated.

V2 and ASN.1: Format changed from WISPr to IR.61. Source is WISPr vendor specific attribute: Location-Info.

OperatorName

No

Yes

V1/V2: Text length 128

ASN.1:
String

Formatted ASCII string that has two parts separated with a colon:

• GSM:TADIG—Prefix string is “GSM” and the following code is a GSMA assigned TADIG code presented in capital ASCII letters.
• REALM:realm—Prefix string is “REALM” and the following code is any valid domain name string that has been acquired from any valid registrar or registry.

The contents are copied directly from GSMA Vendor-Specific Visited-Operator-ID attribute received from NAS. Truncation can be done at the end of the string. The contents are copied directly from GSMA Vendor-Specific Operator- Name attribute received from NAS. Possible truncation can be done at the end of the string.

If both Visited-Operator-ID and Operator-ID are present in the Access-Response, the Visited-Operator-ID is used.

ExtChargingId
