Figure 5.4/1: Sequencing of services<br />

If the reason "resource unavailable (short term problem)" is indicated in the MAP-U-ABORT indication<br />

primitive, the MAP service-user may decide to attempt a new MAP dialogue establishment immediately.<br />

Sequencing of user specific service-primitives is done by the MAP service-user and based on rules<br />

applicable for each MAP service-user instance.<br />

A MAP-NOTICE indication primitive may be received at any time during the active period of a MAP<br />

dialogue.
