5.5 QUERY_SPACE_LINK_SESSION_PROFILE OPERATION<br />

5.5.1 PURPOSE<br />

The QUERY_SPACE_LINK_SESSION_PROFILE (QSLSP) operation is used by UM to<br />

request a copy of previously installed <strong>Space</strong> <strong>Link</strong> Session Profile resident at CM for a given<br />

<strong>Service</strong> Agreement.<br />

5.5.2 PROCEDURE<br />

The procedure for the QSLSP operation is a two-phase operation procedure, which follows<br />

the two-phase operation procedure pattern specified in 3.1.<br />

The QSLSP operation involves the exchange of QUERY_SPACE_LINK_SESSION_-<br />

PROFILE messages. The QSLSP messages are: Query<strong>Space</strong><strong>Link</strong>SessionProfileInvocation<br />

(QSLSP-I), Query<strong>Space</strong><strong>Link</strong>SessionProfileSuccessfulReturn (QSLSP-SR), and<br />

Query<strong>Space</strong><strong>Link</strong>SessionProfileFailedReturn (QSLSP-FR).<br />

The message sequence diagram for the QUERY_SPACE_LINK_SESSION_PROFILE<br />

operation conforms to the stereotyped sequence diagram for the two-phase operation<br />

procedure pattern defined in 3.4.1.3, with the following argument list:<br />

twoPhaseOperationProcedurePatternSequence {UM, CM, QSLSP-I,<br />

QSLSP-SR, QSLSP-FR}<br />

The activity diagram for the QUERY_SPACE_LINK_SESSION_PROFILE operation<br />

conforms to the stereotyped activity diagram for the two-phase operation procedure pattern<br />

defined in 3.4.1.4, with the following argument list:<br />

twoPhaseOperationProcedurePatternActivity {UM, CM, QSLSP-I,<br />

QSLSP-SR, QSLSP-FR,<br />

qslspRoutineTimeout,<br />

qslspUrgentTimeout}<br />
