Table 4-15: Data Set Composition and Relationship Requirements for All
ServicePackageInvocation Messages
CSPD-1

CSPD-4
CSPD-5
CSPD-6
A ServicePackageInvocation message shall contain one and only one of the following:
a) a SpaceLinkSession data set; or
b) a RetrievalTsInstanceRequest data set.
[syntactic validation]
A SpaceLinkSession data set shall contain:
a) one or more ServiceScenario data sets;
b) one ServiceScenarioReference data set; and
c) zero or more SlsTsProfileRespecification data sets.
[syntactic validation]
The primeScenarioRef parameter shall contain the value of the scenarioId parameter of one
of the ServiceScenario data sets.
[service management validation]
If the Service Package contains a SpaceLinkSession data set:
a) the total number of ServiceScenario data sets shall not exceed
maxServiceScenariosPerServicePackage of the Service Agreement;
b) the minimally compliant time span of the Service Package shall not exceed
maxServicePackageTemporalSpan, where the minimally compliant time span of the
Service Package is the greater of:
1) the largest minimumSessionDuration value for all SpaceLinkServiceRequest
data sets within all ServiceScenario data sets within the Service Package; and
2) the difference between the latest allowable start time for all
SpaceLinkServiceRequest data sets within all ServiceScenario data sets
within the Service Package and the earliest allowable stop time for all
SpaceLinkServiceRequest data sets within all ServiceScenario data sets
within the Service Package, where
i) the latest allowable start time for a SpaceLinkServiceRequest data set is equal to
the spaceLinkSessionStartTime plus spaceLinkSessionStartTimeLag;
and
ii) the earliest allowable stop time for a SpaceLinkServiceRequest data set is equal
to the spaceLinkSessionStartTime plus
spaceLinkSessionStartTimeLead plus minimumSessionDuration.
[service management validation]
The total number of transfer service instances enabled in the ServicePackageInvocation shall
not exceed the maxTransferServicesPerServicePackage.
[service management validation]
Each ServiceScenario data set shall contain:
a) one or more SpaceLinkServiceRequest data sets;
b) one or more TrajectoryReference data sets.
