Account-Location

1073

Unsigned32

Ericsson

Represents the logical identity of an account location in an Ericsson Diameter-based credit control system. It is used to identify where an account is logically located within the network infrastructure.

If the location is unknown to the serving element, this AVP must be excluded from the request.

The Account-Location AVP is categorized as:

Static: The value does not change dynamically during the session.

Cached: The value is stored and reused for future requests.

Other-Party-Id

1075

Grouped

Ericsson

Identifies an additional party involved in a session without being charged for it. This AVP complements the Subscription-Id by providing additional details about the other party in the session.

This could represent:

• Calling party

• Called party

• Redirecting party

• Sender or receiver (depending on the service)

The AVP structure is defined as follows:

Other-Party-Id-Type (Mandatory, Enumerated): Defines the type of the other party (e.g., calling party, called party, sender, receiver).

Other-Party-Id-Data (Mandatory, UTF8String): Contains the actual identifier of the other party (e.g., phone number, username).

Other-Party-Id-Nature (Optional, Enumerated): Defines the nature of the identifier (e.g., international, national, local).

The Other-Party-Id AVP is categorized as:

• Static: Its value does not change dynamically during the session.

• Cached: The value can be stored and reused.

The serving element is not allowed to use the additional AVPs (*[AVP]), as they are reserved for internal service use.

Other-Party-Id-Data

1077

UTF8String

Ericsson

Contains the E.164 number (or other identifier) of the other party involved in a session.

This AVP is used in conjunction with:

Other-Party-Id-Type AVP (1076) – Defines the type of the other party (e.g., calling party, called party, sender, receiver).

Other-Party-Id-Nature AVP (1078) – Defines the nature of the identifier (e.g., international, national, local).

Other-Party-Id-Nature

1076

Enumerated

Ericsson

Specifies the nature of the address stored in the Other-Party-Id-Data AVP (1077). It defines whether the other party's number is an international number, national number, or unknown.

Used in conjunction with:

Other-Party-Id-Data (1077) – Contains the actual identifier (e.g., E.164 phone number).

Other-Party-Id-Type (1075) – Defines what type of party is being identified (e.g., calling party, called party).

If omitted, the default value is INTERNATIONAL (1) when the Other-Party-Id-Type AVP is set to END_USER_E164 (0).

Enumerated Values:

0: UNKNOWN: Address nature is unknown.

1: INTERNATIONAL (Default): The number is an E.164 international number (default value if AVP is omitted).

2: NATIONAL: The number is a national (significant) number, meaning it is formatted for use within a specific country.

Other-Party-Id-Type

1078

Enumerated

Ericsson

Used to define the format/type of identifier carried within the Other-Party-Id (1075). Specifies how the identifier should be interpreted (e.g., E.164 number, IMSI, SIP URI, NAI).

Used alongside:

Other-Party-Id-Data (1077) – Holds the actual identifier (e.g., phone number, IMSI, SIP URI).

Other-Party-Id-Nature (1076) – Defines the nature of the address (e.g., international, national).

Only END_USER_E164 (0) is supported in the SCAPv2 service context.

Enumerated Values:

0: END_USER_E164: The identifier is in E.164 phone number format (e.g., "+15551234567"). Other-Party-Id-Nature AVP (1076) must be used to specify whether it's an international or national number.

1: END_USER_IMSI: The identifier is an International Mobile Subscriber Identity (IMSI) used for mobile network subscriber identification.

2: END_USER_SIP_URI: The identifier is a SIP URI (Session Initiation Protocol Uniform Resource Identifier), used in VoIP/IMS communications (e.g., "sip:user@example.com").

3: END_USER_NAI: The identifier is a Network Access Identifier (NAI), typically used in authentication and roaming scenarios.

Result-Code-Extension

N/A

Unsigned32

Ericsson

Used to extend the standard Diameter Result-Code AVP. It provides additional error codes or customized result information beyond the standard Result-Code AVP (268).

Service-Provider-Id

1081

UTF8String

Ericsson

Used to identify a service provider in Diameter-based credit control and charging applications. The identifier format is operator-specific, meaning its structure and interpretation depend on the specific Ericsson system implementation.

The AVP is in this service context defined as ‘static’ and ‘cached’, meaning the value is predefined and stored in the system for quick access.

Subscription-Id-Location

1074

UTF8String

Ericsson

Defines the geographical location of a user identified by the Subscription-Id AVP. The value is encoded as a UTF8String and follows the E.164 numbering plan (ITU-T E.164 standard).

The AVP is in this service context defined as ‘static’ and ‘cached’, meaning the location is predefined and stored for efficient retrieval.

Used in Ericsson DAAC/SCAPv2-based systems, particularly when Mobile Number Portability (MNP) functions are required for terminating traffic.

The Subscription-Id-Location includes the following components:

Country Code (CC): Mandatory

National Destination Code (NDC): Recommended

Local Subscriber Number (LSP): Optional

Traffic-Case

1082

Unsigned32

Ericsson

Specifies the type of traffic scenario for which a charged event is being processed in an Ericsson-based Diameter Credit-Control system.

Used to classify different types of charging scenarios.

The AVP is in this service context defined as ‘static’ and ‘cached’ – meaning its value is predefined and does not change dynamically.

Values:

0 – 19: Reserved for future use

20: Originating Service Charging (For events where the user is the caller/sender)

21: Terminating Service Charging (For events where the user is the receiver)

22 – MAXRANGE: Reserved for future use (MAXRANGE represents the maximum defined unit range)
