Space Link Extension - Service Management - CCSDS

DRAFT RECOMMENDED STANDARD FOR SPACE LINK EXTENSION SERVICE MANAGEMENT
The interactions between Utilization Management (UM) and Complex Management (CM)
are the domain of SLE-SM. The SLE transfer service interactions between the users in the
MDOS and the SLE Complex are the subject of the SLE transfer CCSDS Recommended
Standards. Communications across the space link are the subject of CCSDS Recommended
Standards for RF, modulation, coding, and data links. Neither the interactions between UM
and users, nor those between CM and the resources that actually provide the SLE transfer
and TT&C services, nor internal management of CM or UM, are covered by this
Recommended Standard.
2.1.2 THE PURPOSE OF SLE SERVICE MANAGEMENT
The purpose of SLE-SM is to standardize and automate, as far as practicable, those
interactions between users and providers of space link and SLE services that are required to
set the values of the parameters of space link and SLE transfer services. In addition, SLE-SM
provides the means to configure the resources needed by the user and provider to execute
those services. In essence, SLE-SM provides a standard way for the user and provider:
a) to set the values of the parameters involved in space link and SLE services;
b) to specify the services needed to execute space link and SLE services;
c) to configure ground stations for the establishment of space links;
d) to configure ground stations for processing of forward and return space link data;
e) to arrange timely provision of transfer services;
f) to disseminate Trajectory Predictions.
CM presents the services performed within the SLE Complex in a standard way to the user,
as defined in detail in the later sections of this document.
The roles of UM and CM, and the SLE-SM services that are set up between them, are
outlined in the following subsections.
2.1.3 SLE UTILIZATION MANAGEMENT
SLE Utilization Management is the function within the MDOS that coordinates the requests
by users for space link and SLE services from the SLE Complex.
Utilization Management role:
a) Requests periods of provision of space link services and space link extension transfer
services;
b) Provides configuration information for RF, modulation, space link service, and space
link extension transfer service;
