Release default bearer without releasing dedicated bearer?

Question

Is it possible to release default bearer without releasing dedicated bearer? Please suggest?

Answer 1

It is not possible.

Whenever a default bearer is released, corresponding dedicated bearers are also removed.

Answer 2

You cannot establish Dedicated Bearer(s) without Default Bearer, although you can have few Default ones without single Dedicated one.

Answer 3

The default bearer provides the UE with IP connectivity and the same IP address (es) are to be used by dedicated bearer(s).

So release of default bearer triggers release of all associated dedicated bearer(s) else UE may be without IP.
