# Field Reference for CDRs in P-GW

This chapter provides a reference for CDR fields supported by the system for use in PGW-CDRs.

A complete list and descriptions of supported CDR fields is provided in the Field Descriptions for CDRs in P-GW chapter of this reference.

IMPORTANT:

For more information on custom dictionaries, contact your Cisco account representative.

The category column in all tables use keys described in the following table.
Table 1. Dictionary Table Key

M | Mandatory | A field that must be present in the CDR.
C | Conditional | A field that must be present in a CDR if certain conditions are met.
OM | Operator Provisionable: Mandatory | A field that an operator has provisioned and must be included in the CDR for all conditions.
OC | Operator Provisionable: Conditional | A field that an operator has provisioned that must included in the CDR if certain conditions are met.

CDR Fields Supported in PGW-CDRs

The table in this section lists the PGW-CDR fields present in the available GTPP dictionaries.

custom24, custom40, and custom42 Dictionaries

PGW-CDR fields are based on 3GPP TS 32.298 V8.5.0.

Field | Category | Description
--- | --- | ---
Record Type | M | P-GW IP CAN bearer record
Served IMSI | M | IMSI of the served party (if Anonymous Access Indicator is FALSE or not supplied)
P-GW Address | M | The control plane IP address of the P-GW used.
Charging ID | M | IP CAN bearer identifier used to identify this IP CAN bearer in different records created by PCNs
Serving Node Address | M | List of serving node control plane IP addresses (e.g. SGSN, MME, etc.) used during this record.
Access Point Name Network Identifier | OM | The logical name of the connected access point to the external packet data network (network identifier part of APN).
PDP/PDN Type | OM | Indicates PDP type (IP, PPP, or IHOSS:OSP) or PDN type (IPv4, IPv6, or IPv4v6).
Served PDP/PDN Address | OC | IP address allocated for the PDP context / PDN connection (IPv4 or IPv6), if available.
Dynamic Address Flag | OC | Indicates whether served PDP/PDN address is dynamic, which is allocated during IP CAN bearer activation, initial attach (E-UTRAN or over S2x) and UE requested PDN connectivity. This field is missing if address is static.
Record Opening Time | M | Timestamp when IP CAN bearer is activated in this S-GW or record opening time on subsequent partial records.
Duration | M | Duration of this record in the S-GW.
Cause for Record Closing | M | The reason for the release of record from this P-GW.
Diagnostics | OM | A more detailed technical reason (as defined in TS 32.250) for the release of the connection.
Record Sequence Number | C | Partial record sequence number, only present in case of partial records.
Node ID | OM | Name of the recording entity.
Local Record Sequence Number | OM | Consecutive record number created by this node. The number is allocated sequentially including all CDR types.
APN Selection Mode | OM | An index indicating how the APN was selected.
Served MSISDN | OM | The primary MSISDN of the subscriber.
Charging Characteristics | M | The Charging Characteristics applied to the IP CAN bearer.
Charging Characteristics Selection Mode | OM | Information about how Charging Characteristics were selected.
Serving Node PLMN Identifier | OM | Serving node PLMN Identifier (MCC and MNC) used during this record, if available.
Served IMEISV | OC | IMEISV of the ME, if available.
RAT Type | OC | Indicates the Radio Access Technology (RAT) type currently used by the Mobile Station, when available.
MS Time Zone | OC | Indicates the offset between universal time and local time in steps of 15 minutes where the MS currently resides.
User Location Information | OM | Contains the User Location Information of the MS as defined in TS 29.060 for GPRS case, and in TS 29.274 for EPC case, if available.
List of Service Data | OM | List of changes in charging conditions for all service data flows within this IP CAN bearer categorized per rating group or per combination of the rating group and service id.
Data Service Volume Block | OM | Service data container associated with a service condition change on a service data flow (categorized per rating group or per combination of the rating group and service id) within this IP CAN bearer.
Serving node Type | M | List of serving node types in control plane. The serving node types listed here map to the serving node addresses listed in the field “Serving node Address” in sequence.
Served MNNAI | OC | Mobile Node Identifier in NAI format (based on IMSI), if available.
P-GW PLMN Identifier | OC | PLMN identifier (MCC MNC) of the P-GW.
Start Time | OC | The time when User IP-CAN session starts, available in the CDR for the first bearer in an IP-CAN session.
Stop Time | OC | The time when User IP-CAN session is terminated, available in the CDR for the last bearer in an IP-CAN session.
PDN Connection Id | OM | PDN connection (IP-CAN session) identifier to identify different records belonging to same PDN connection.

Notes:

- In the case of custom40 GTPP dictionary, the following two values are also supported for the PGW-CDR field “Charging Characteristics Selection Mode” in addition to the standard values as in the custom24 GTPP dictionary.
  - AAASupplied (6)
  - GWOverride (7)
- custom42 dictionary: This customer-specific file format contains PGW-CDRs that are encoded in ASCII format.
- For custom42 dictionary, Record Sequence Number is 12 byte ASCII value and last 2 bytes will always be zero.
- In the case of custom42 dictionary, PGW-CDR is closed as the final record of a subscriber session for the following events:
  - Detach Request received from UE
  - Delete bearer context request received from S-GW.
  - Manual subscriber clearing
  - Abnormal Releases such as path failures
