Last updated on FEBRUARY 26, 2019

Information in this document applies to any platform.


Two (or more) Balance Types can be configured in a Balance Type Cascade and can therefore be used to charge a service.

It is possible that the first Balance Type in the cascade expires during the charging session. In that case, it is expected that

  • The confirmed reservations (already committed) and the ongoing reservation (the last granted) stay valid.

  • Any new reservation goes to the next Balance Type in the cascade (if any) : no more reservation can be made on the - now expired - Balance Type.

  • The costs bared by a Balance Type before it expired during the session remain on the expired Balance Type.

  • The costs bared by the next - non expired - Balance Type in the cascade to continue the session goes on that next Balance Type.

  • A "mid-session expiry EDR" (CDR_TYPE=3 with the tag STATUS=UNRESERVED_BALANCE_EXPIRED) is created when a Balance Type expires in the middle of a session and when createEdrForReservedExpiredBuckets is enabled.

Various types of symptoms may happen depending on the specific scenario, for example :
