Space Link Extension - Service Management - CCSDS

DRAFT RECOMMENDED STANDARD FOR SPACE LINK EXTENSION SERVICE MANAGEMENT
2.2.3.4 DELETE_SERVICE_PACKAGE
UM invokes the DELETE_SERVICE_PACKAGE operation to remove an existing Service
Package from CM. Upon successful completion of this operation CM will no longer carry
the Service Package in its operational schedule; i.e., the resources needed to provide the
services will be released.
2.2.3.5 QUERY_SERVICE_PACKAGE
UM invokes the QUERY_SERVICE_PACKAGE operation to obtain the contents of an
existing Service Package. With the potential exception of the prime scenario designation, the
contents of the returned Service Package are identical to that provided in the last successful
return message for either a CSP or RSP operation (i.e., CSP-SR and RSP-SR). The return
information will also reflect an updated prime scenario designation as a result of successful
SELECT_ALTERNATE_SCENARIO operations, if any, applied to the Service Package since
the CSP or RSP.
2.2.3.6 SELECT_ALTERNATE_SCENARIO
UM may invoke the SELECT_ALTERNATE_SCENARIO operation for service provision in
accordance with an alternate scenario of an existing Service Package. Since, as a condition of
accepting either a CSP-I or RSP-I, CM commits to providing sufficient resources to
support all of the alternate scenarios in the Service Package, an alternate scenario can be
invoked on a much shorter time scale and with a much higher probability of success than if
UM were to invoke a CSP or RSP operation.
2.2.3.7 APPLY_NEW_TRAJECTORY
UM invokes an APPLY_NEW_TRAJECTORY operation for an existing Service Package to
indicate that Doppler compensation and antenna pointing are to be in reference to the new
trajectory. CM re-evaluates all of the scenarios of the existing Service Package that UM
indicates are to be in reference to the new trajectory to ensure that it (CM) can continue to
provide the agreed-upon support. If it can continue to provide the services, CM returns the
updated Service Package information, indicating the new, updated trajectory references. If it
cannot, CM returns the appropriate error information, but does not update the Service
Package to utilize the updated trajectory information; i.e., the Service Package is retained as
is prior to the ANT-I.
2.2.3.8 APPLY_NEW_SPACE_LINK_EVENTS_PROFILE
UM invokes an APPLY_NEW_SPACE_LINK_EVENTS_PROFILE operation for an existing
Service Package to indicate that an events profile, currently referenced by one or more
service packages, is to be superseded by a different events profile, which must already be
