Notes:

  • The subfields included in other fields are marked Mandatory even if the main field is optional. For example, the list of service containers is optional, but if there is at least one container, then all subfields for the container that are marked as Mandatory will be included.

  • The field "Served PDP PDN Address Extension"(servedPDPPDNAddressExt) is not part of the 3GPP 32.298 v8.5.0 specification. This field will be available in the CDR only when the CLI command gtpp attribute served-pdp-pdn-address-extension is configured in the GTPP Server Group Configuration Mode. This field is disabled by default. For more information on this command, refer to the Command Line Interface Reference.

  • Record Extensions (recordExtensions) is a customer-specific field. This field will be available in the CDR only when the CLI command gtpp trigger direct-tunnel is configured in the GTPP Server Group Configuration Mode. This field is disabled by default. For more information on this command, refer to the Command Line Interface Reference.

  • In releases prior to 14.0, the CGISAIChange service condition is present in LOSDV of GGSN CDR even if ULI Change trigger is disabled. In 14.0 and later releases, if the ULI Change trigger is disabled and if the ULI is changed, the CGISAIChange service condition is not present in LOSDV of GGSN CDR.

  • Rulebase change triggered from any external interface e.g. OCS/PCRF, will generate CDR with closure reason "Management Intervention". This change is applicable to all standard dictionaries except for custom42 GTPP dictionary as it is customized to suppress interim CDR.

  • In releases prior to 16, if there was a LOSDV bucket created between the packet arrival time and service-idle-out expiry time, no data counts were reported. So, a zero-volume LOSDV was generated for service idle timeout scenario. In 16 and later releases, if there are no data counts available for a service flow, the LOSDV for service idle timeout will not be created. The service-idle timeout will be started only when the next data packet arrives.

    This behavior change is applicable to eG-CDRs and PGW-CDRs for all GTPP dictionaries except custom5 and custom40 dictionaries.

Charging ID

5

M

This field is a charging identifier, which can be used together with the GGSN address to identify all records produced in the GGSN involved in a single PDP context. The Charging ID is generated by the GGSN at PDP context activation and is transferred to the context requesting SGSN. At an inter-SGSN routing area update the charging ID is transferred to the new SGSN as part of each active PDP context.

The possible values for the charging ID, which are defined in TS 29.060 are 1-4,294,967,295 and those values are encapsulated in following scheme in the CDR-field:

1 - 127 850101-85017F

128 – 32,767 85020080 -85027FFF

32,768 – 8,388,607 8503008000 -85037FFFFF

8,388,608 – 2,147,483,647 850400800000 -85047FFFFFF

  • Base Time Interval identifies the length of the base time interval, for controlling the reporting of time based usage, in seconds

Sequence

Variable length

96

Notes:

  • LOTV related changes:

    • A new IE is included for LOTV container i.e. User location information.

    • The list of traffic data volumes now supports RAI and CGI/SAI changes, i.e. whenever RAI and/or CGI/SAI changes are detected; it will result in a "List of Traffic Data Volumes" container being added to the CDR, if location reporting is required and a report of CGI/SAI change is received.

  • LOSDV related changes:

    • Time Quota mechanism: Contains two further subfields and is included if envelope reporting is required:

      • Time Quota Type identifies the mechanism by which time-based usage should be reported — as defined in TS 32.299.

      • Base Time Interval identifies the length of the base time interval, for controlling the reporting of time-based usage, in seconds.

    • User location information will be included in the LOSDV container in the R7 eG-CDRs.

    • The "Service Change Condition" cause changes are as follows:

      • Time limit eG-CDRs where the corresponding service change condition now has been changed to "Time Limit". Earlier there was no specific service change condition and instead "Time Exhausted" was used.

      • Volume limit eG-CDRs where the corresponding service change condition now has been changed to "Volume Limit". Earlier there was no specific service change condition and instead "Volume Exhausted" was used.

      • eG-CDRs that are generated as a result of MS-TimeZone change will have service change condition as "Record closure".

    • custom19 dictionary has Rel. 7 related changes.

  • The field "Served PDP PDN Address Extension"(servedPDPPDNAddressExt) is not part of the 3GPP 32.298 v8.5.0 specification. This field will be available in the CDR only when the CLI command gtpp attribute served-pdp-pdn-address-extension is configured in the GTPP Server Group Configuration Mode. This field is disabled by default. For more information on this command, refer to the Command Line Interface Reference.

  • Record Extensions (recordExtensions) is a customer-specific field. This field will be available in the CDR only when the CLI command gtpp trigger direct-tunnel is configured in the GTPP Server Group Configuration Mode. This field is disabled by default. For more information on this command, refer to the Command Line Interface Reference.

  • In releases prior to 14.0, the CGISAIChange service condition is present in LOSDV of GGSN CDR even if ULI Change trigger is disabled. In 14.0 and later releases, if the ULI Change trigger is disabled and if the ULI is changed, the CGISAIChange service condition is not present in LOSDV of GGSN CDR.

  • Rulebase change triggered from any external interface e.g. OCS/PCRF, will generate CDR with closure reason "Management Intervention". This change is applicable to all standard dictionaries except for custom42 GTPP dictionary as it is customized to suppress interim CDR.

  • In releases prior to 16, if there was a LOSDV bucket created between the packet arrival time and service-idle-out expiry time, no data counts were reported. So, a zero-volume LOSDV was generated for service idle timeout scenario. In 16 and later releases, if there are no data counts available for a service flow, the LOSDV for service idle timeout will not be created. The service-idle timeout will be started only when the next data packet arrives.

    This behavior change is applicable to eG-CDRs and PGW-CDRs for all GTPP dictionaries except custom5 and custom40 dictionaries.
