SGW-CDR Field Reference Tables

 

This chapter provides reference tables for the CDR fields reported as part of S-GW CDRs (SGW-CDRs) generated by the system.

A complete list of supported CDR fields is provided in the SGW-CDR Field Descriptions chapter of this reference guide.

The specific CDRs reported in SGW-CDRs and their encoding are user-selectable via GTPP dictionaries. The use of GTPP dictionaries is configurable using the gtpp dictionary command in the Context Configuration Mode of the system’s Command Line Interface (CLI).

This section provides information on the fields reported in SGW-CDRs for the GTPP dictionaries.

Important: For more information on custom dictionaries, contact your local service representative.

The category column in all tables use keys described in the following table.

Dictionary Table Key

Abbreviation	Meaning	Description
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.
O	Operator Provisionable: Mandatory	A field that an operator has provisioned and must be included in the CDR for all conditions.
O	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 SGW-CDRs

The tables in this section list the SGW-CDR fields present in the available GTPP dictionaries.

custom6, custom11, and custom24 Dictionaries

For custom6 and custom24 dictionaries, CDR fields are based on 3GPP TS 32.298 v8.7.0 and 3GPP TS 32.251 v8.8.0.

For the custom11 dictionary, CDR fields are based on 3GPP TS 32.298 v8.5.0 and 3GPP TS 32.251 v8.6.0.

Field	Category	Description
Record Type	M	S-GW IP CAN bearer record
Served IMSI	M	IMSI of the served party (if Anonymous Access Indicator is FALSE or not supplied)
S-GW Address used	M	The control plane IP address of the S-GW used.
Charging ID	M	IP CAN bearer identifier used to identify this IP CAN bearer in different records created by PCNs
PDN Connection Id	O	The PDN connection (IP-CAN session) identifier to identify different records belonging to same PDN connection.
Serving Node Address	M	List of serving node control plane IP addresses (e.g. SGSN, MME, etc.) used during this record.
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.
S-GW Change	O	Present if this is the first record after S-GW change.
PGW PLMN Identifier	O	PLMN identifier (MCC MNC) of the PGW used.
Access Point Name Network Identifier	O	The logical name of the connected access point to the external packet data network (network identifier part of APN).
PDP/PDN Type	O	Indicates PDN type (i.e IPv4, IPv6 or IPv4v6).
Served PDP/PDN Address	O	IP address allocated for the PDP context / PDN connection, i.e. IPv4 or IPv6, if available.
Dynamic Address Flag	O	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.
List of Traffic Data Volumes	O	A list of changes in charging conditions for this QCI/ARP pair, each change is time stamped. Charging conditions are used to categorize traffic volumes, such as per tariff period. Initial and subsequently changed QoS and corresponding data values are also listed. Refer to the List of Data Traffic Volumes table in this chapter.
Record Opening Time	M	Time stamp when IP CAN bearer is activated in this S-GW or record opening time on subsequent partial records.
MS Time Zone	O	Contains the MS Time Zone the MS is currently located as defined in TS 29.060 [203], if available.
Duration	M	Duration of this record in the S-GW.
Cause for Record Closing	M	The reason for the release of record from this S-GW.
Diagnostics	O	A more detailed reason for the release of the connection.
Record Sequence Number	C	Partial record sequence number, only present in case of partial records.
Node ID	O	Name of the recording entity.
Record Extensions	O	A set of network operator/manufacturer specific extensions to the record. Conditioned upon the existence of an extension.
Local Record Sequence Number	O	Consecutive record number created by this node. The number is allocated sequentially including all CDR types.
APN Selection Mode	O	An index indicating how the APN was selected.
Served MSISDN	O	The primary MSISDN of the subscriber.
User Location Information	O	Contains the User Location Information of the MS as defined in TS 29.060 [203] for GPRS case, and in TS 29.274 [210] for EPC case, if available.
Charging Characteristics	M	The Charging Characteristics applied to the IP CAN bearer.
Charging Characteristics Selection Mode	O	Information about how Charging Characteristics were selected.
IMS Signalling Context	O	Included if the IM-CN Subsystem Signalling Flag is set. IP CAN bearer is used for IMS signalling.
P-GW Address used.	O	The P-GW IP Address for the Control Plane.
Serving Node PLMN Identifier	O	Serving node PLMN Identifier (MCC and MNC) used during this record, if available.
Served IMEISV	O	IMEISV of the ME, if available
RAT Type	O	Indicates the Radio Access Technology (RAT) type currently used by the Mobile Station, when available. This RAT type is defined in TS 29.060 [204] for GTP case, in TS 29.274 [210] for eGTP case and in TS 29.275 [211] for PMIP case.
Start Time	O	The time when User IP-CAN session starts, available in the CDR for the first bearer in an IP-CAN session.
Stop Time	O	The time when User IP-CAN session is terminated, available in the CDR for the last bearer in an IP-CAN session .

Notes:

•	custom11 and custom24 dictionaries: All IP addresses are encoded in binary format.

•	custom6 dictionary: All IP addresses are in ASCII format.

List of Traffic Data Volumes

Traffic Data Volume	Category	Description
Change Of Charging Condition	M	Each traffic volume container contains details related to a charging condition as described in the following subsections. A new container is usually created for a QoS change and for tariff changes.
Data Volume GPRS Uplink	M	The Data Volume GPRS Uplink field is a part of the ChangeOfCharCondition element in the List of Traffic Volumes. It includes the number of octets received in the uplink direction during the timeframe specified by the container. For each new container, the counter is reset and does not accumulate. The data counted already includes the IP PDP bearer protocols i.e. IP or PPP.
Data volume GPRS Downlink	M	The Data Volume GPRS Downlink field is a part of the ChangeOfCharCondition element in the List of Traffic Volumes. It includes the number of octets transmitted in the downlink direction during the timeframe specified by the container. For each new container, the counter is reset and does not accumulate. The data counted already includes the IP PDP bearer protocols i.e. IP or PPP.
Change Condition	M	The Change Condition field is part of the ChangeOfCharCondition element in the List of Traffic Volumes. It defines the reason for closing the container.
Change time	M	The Change Time field is part of the ChangeOfCharCondition element in the List of Traffic Volumes. It provides the local time when a change condition (e.g. record closure) occurred and the container was closed.
User Location Information	O	This field contains the User Location Information as described in TS 29.274 for eGTP case (e.g. CGI, SAI, RAI TAI and ECGI). The field is provided by the SGSN/MME and transferred to the S-GW/P-GW during the IP-CAN bearer activation/modification. User Location Information contains the location (e.g. CGI/SAI, ECGI/TAI or RAI) where the UE is located and used during the transfer of the data volume captured by the container (applicable only to the SGW-CDR). This is included in the Traffic data container only if previous container's change condition is "user location change". Note the user location information in SGW-CDR main level contains the location where the UE was when CDR was opened.
EPC Qos Requested	O	In case of IP-CAN bearer specific container this contains authorized QoS for the IP-CAN bearer. First container for each QCI/ARP pair includes this field. In following containers this field is present if previous change condition is "QoS change". This field is applicable only in SGW-CDR.
