Resolution
In the Call Session Control Platform (CSCP) system, no independent process cleans expired registrations. Expired registrations delete from the database because of these two different scenarios:
- The subscriber is removed from the CSCP database.
- The registrar, one of the functions of the SE, removes all of the expired registrations when a subscriber sends in a registration.
This allows the system to retain expired registrations for an active subscriber that does not currently use the ready link service. The reasons for this include:
The subscriber intentionally turns off the push-to-talk (PTT) service.
The subscriber improperly de-registers and is not currently in a coverage area.
The trend for this actually differs with the type of service provided.
For example, pre-paid or part-time services more often have expired registrations in the database because they are considered active but the services can be unused for a period of time.
