Selective Updates for Login Devices

For login devices identified by an Diameter Session Initiation Protocol Uniform Resource Identifier (SIP URI), a Network Access Identifier (NAI), or a PrivateId, you must configure selective updates to map the device identifier string sent in the Diameter Subscription-Id AVP > Subscription-Id-Type to LoginId or AccessId in MtxDiamSubscriberMsg.

MtxDiamSubscriberMsg Fields lists the MtxDiamSubscriberMsg fields populated by the Subscription-Id-Type AVP values.

Table 1. MtxDiamSubscriberMsg Fields
MtxDiamSubscriberMsg Field	Subscription-Id-Type
`SipUri`	2 — END_USER_SIP_URI
`Nai`	3 — END_USER_NAI
`PrivateId`	4 — END_USER_PRIVATE

The Charging Server uses the LoginId and AccessId fields for login device identification. You must use selective updates to copy values from the MtxDiamSubscriberMsg subscription ID type fields (SipUri, Nai, PrivateId) to the MtxDiamSubscriberMsg LoginId and AccessId fields. If values for both are present, the answer to the following engine configuration question determines which value is used for device identification: What field should be used to locate the login device if both the LoginId and AccessId are present?.

The default field is LoginId.

The selective update must be on the Charging Server's input interface.

In the following example, the selective update looks in MtxDiamSubscriberMsg for SipUri and Nai and, if found, copies the field values to the LoginId and AccessId fields respectively.
