1  ScopeWord‑p. 6

The present document is meant to function as guidance in the work of other 3GPP work groups or work items. Such work may include conclusion on how to achieve detailed Stage 1 service requirements or suggestion of a set of recommended RAB parameters giving satisfactory user-to-user quality for a circuit switched multimedia service using 3G-324M.
