SGSN and Mobility Management Charging Detail Record Field Reference Tables

 

 

The SGSN provides CDRs that are compliant to the definitions in 3GPP TS32.298. When necessary and required, modifications to the standardized behavior can be implemented in different dictionaries which can be selected in the configuration file. This provides the flexibility to adapt to a customer's needs, e.g. to a legacy post-processing billing interface, while keeping the standard behavior for other needs.

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).

The SGSN provides CDRs that are compliant to the specifications identified in this chapter. When necessary and required, modifications to the standardized behavior can be implemented in different dictionaries which can be selected in the configuration file. This provides the flexibility to adapt to a customer's needs, e.g. to a legacy post-processing billing interface, while keeping the standard behavior for other needs.

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.

S-CDR fields for TS 32.215 v 4.5.0 (R4).

 

Field	Category	Description
Record Type	M	SGSN PDP context record.
Served IMSI	M	IMSI of the served party.
Served IMEI	OC	IMEI of the ME, if available.
Served MSISDN	OM	The primary MSISDN of the subscriber.
SGSN Address	OM	The IP address of the current SGSN.
Charging ID	M	PDP context identifier used to identify this PDP context in different records created by GSNs.
GGSN Address Used	M	The control plane IP address of the GGSN currently used. The GGSN address is always the same for an activated PDP context.
APN Selection Mode	OM	An index indicating how the APN was selected.
PDP Type	OM	PDP type, i.e. IP, PPP, or IHOSS:OSP.
Served PDP Address	OC	PDP address, i.e. IPv4 or IPv6 address. This parameter shall be present except when both the PDP type is PPP and dynamic PDP address assignment is used.
Charging Characteristics	M	The Charging Characteristics applied to the PDP content.
Charging Characteristics Selection Mode	OM	Holds information about how Charging Characteristics were selected.
Dynamic Address Flag	OC	The presence of this field indicates that the Served PDP Address was dynamically assigned during context activation.
MS Network Capability	OM	The Mobile Station Network Capability.
Node ID	M	Name of the recording entity.
Access Point Name Network Identifier	M	The logical name of the connected access point to the external packet data network (network identifier part of APN).
Access Point Name Operator Identifier	M	The Operator Identifier part of the APN.
System Type	OC	Indicates the type of air interface used, e.g. UTRAN. This field ispresent when either the UTRAN or GERAN air-interface is used. It isomitted when the service is provided by a GSM air interface.
Record Opening Time	M	Time stamp when PDP context is activated in this GGSN or record opening time on subsequent partial records.
Duration	M	Duration of this record in the GGSN.
Cause for Record Closing	M	The reason for the release of record from this SGSN.
List of Traffic Data Volumes	M	A list of changes in charging conditions for this PDP context, each 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.
Routing Area Code (RAC)	OM	Contains the RA code of the area where the MS is located when the (partial) record is opened.
Location Area Code	OM	Contains the Location Area Code of the area where the MS is located when the (partial) record is opened.
Cell Identifier	OM	Contains the CI (GSM) or the SAC (WCDMA) of the cell where the MS is located when the S-CDR is opened. The first partial or single S-CDR reports the current cell identifier at PDP context activation. For any subsequent partial S-CDRs, the accuracy of the reported cell identifier is limited to the cell identifier for the last RA update reported by the MS.
SGSN Change	C	Indicate that this is the first record after an inter-SGSN routing area update in new SGSN and an intra-SGSN inter-system change.
Record Sequence Number	C	Partial record sequence number, only present in case of partial records.
Local Record Sequence Number	M	Consecutive record number created by this node. The number is allocated sequentially including all CDR types.

 

Notes:

 

•	The indefinite length ASN encoding is used. i.e no length part which indicates the total length of CDR.

•	All IP addresses are in binary format.

•	All bools are encoded as 0x01 (In ASN STD 3GPP they are encoded as 0xff).

•	RNCUnsent Volume field is not present.

•	The QOS length should limited to max of 12 bytes irrespective of what was requested/negotiated.

•	ISRAU 'cause for record closure' is the SGSN Change.

•	IMEISV shall be sent if available else IMEI shall be sent.

•	System Type field is present in S-CDR only if access type is UTRAN.

•	In the case of intra-sgsn-inter-system change (2G<->3G handover within same box), the cause for record closure is ‘SGSN Change’.

•	The fields should be sent in same order as per the table.
