Behavior Change
Previous Behavior: CHF used to reject the charging data request from SMF due to the invalid format of the subscriberIdentifier included in the request message.
New Behavior: 3GPP TS 32.291 specification introduces a new subscriberIdentifier type in Release 15.4.0. The compliance profile configuration for the nchf-convergedcharging service now supports the 15.4.0 specification version. That means, the CHF server is configured to use the 15.4.0 3GPP specification compliance version to avoid rejection of the charging data request.
