DRAFT RECOMMENDED STANDARD FOR SPACE LINK EXTENSION SERVICE MANAGEMENT ANTC-5 ANTC-6 ANTC-7 ANTC-8 If the SLE Complex has locally defined ANT-I requirements in addition to those specified in this Recommended Standard that could cause a ANT-I to be denied, CM shall validate that the ANT-I conforms to all such local requirements. [service management validation] CM shall validate that the sleSmCreatorName associated with the ANT-I is the same as the sleSmCreatorName of the Service Package associated with the servicePackageId referenced by the servicePackageRef in the ANT-I. [service management validation] CM shall validate that the new Trajectory Prediction start and stop times are consistent with all affected Service Scenarios in the Service Package. If any of the affected Service Scenarios are not consistent with the new Trajectory Prediction start and stop times, CM shall reject the ANT-I and respond to UM with a ANT-FR. NOTES: 1 The affected Service Scenarios are defined as those that have a trajectoryRef parameter that matches the existingTrajectoryRef parameter of the ANT-I (for the Service Package identified by the servicePackageRef parameter of the ANT-I). 2 Consistency of trajectory start (T1) and stop time (T2) is determined by comparing against the scheduledSpaceLinkSessionStartTime (S1) and scheduledSpaceLinkSessionStopTime (S2) parameters of the affected Service Scenario and validating that T1 = S2 3 In addition to checking the consistency of the new trajectory start and stop times, CM may perform additional validation if further CM-internal conditions need to be met (such as internal cable limitations for antenna pointing, Doppler dynamic limitations, etc.). [service management validation] CM shall validate that the required resources are available to fulfill the Service Package with the new Trajectory Prediction data. If the required resources are not available, CM shall cease processing the ANT-I and respond to UM with a ANT-FR message containing a AntDenial data set. [service management validation] ANTC-9 If CM is unable to validate and perform the ANT operation prior to expiration of minServiceDefinitionLeadTime, CM may terminate the operation and issue an ANT-FR. [service management validation] ANTC-9A CM shall validate that the scheduledServicePackageStopTime for the referenced Service Package has not already passed. [service management validation] ANTC-9B CM shall validate that the Service Package referenced by the servicePackageRef parameter of the ANT-I: a) has been established; b) has not been deleted; and c) has not been cancelled. [service management validation] ANTC-10 If the ANT-I is valid, CM shall update all affected Service Scenarios in the Service Package to reference the new Trajectory Prediction and send an ANT-SR message to UM. [Perform operation] ANTC-11 CM shall conform to all ANT-SR, ANT-FR and ANT-AR Data Set Composition and Relationship Requirements when creating and transmitting a ANT-SR, ANT-FR and ANT-AR, as specified in table 4-69, table 4-70, and table 4-71, respectively.

DRAFT RECOMMENDED STANDARD FOR SPACE LINK EXTENSION SERVICE MANAGEMENT 4.7.4 ApplyNewTrajectoryInvocation (ANT-I) MESSAGE (UM CM) 4.7.4.1 General The ApplyNewTrajectoryInvocation (ANT-I) message conforms to the data set composition and relationship requirements for, and inherits the parameters of, the stereotype, as specified in 3.3.4.3.2. Figure 4-21 shows the message structure of the ANT-I as a class diagram. Figure 4-21: ANT-I Message Structure, Presented in a Class Diagram 4.7.4.2 Parameters The ServicePackageReference data set is defined in table 4-18. The TrajectoryPredictionInformation data set is shown in table 4-67. Table 4-67: TrajectoryPredictionInformation Data Set Name Definition/Description Data Type Units Applicable Service Agreement Parameter existingTrajectoryRef Contains the value of a String256 n/a n/a trajectoryId that identifies the Trajectory Prediction currently referenced by one or more Service Scenarios in the Service Package. newTrajectoryRef Contains value of a trajectoryId that identifies the Trajectory Prediction that is to replace the existingTrajectoryRef for one or more Service Scenarios in the Service Package.
