DRAFT RECOMMENDED STANDARD FOR SPACE LINK EXTENSION SERVICE MANAGEMENT<br />

The interactions between Utilization <strong>Management</strong> (UM) and Complex <strong>Management</strong> (CM)<br />

are the domain of SLE-SM. The SLE transfer service interactions between the users in the<br />

MDOS and the SLE Complex are the subject of the SLE transfer <strong>CCSDS</strong> Recommended<br />

Standards. Communications across the space link are the subject of <strong>CCSDS</strong> Recommended<br />

Standards for RF, modulation, coding, and data links. Neither the interactions between UM<br />

and users, nor those between CM and the resources that actually provide the SLE transfer<br />

and TT&C services, nor internal management of CM or UM, are covered by this<br />

Recommended Standard.<br />

2.1.2 THE PURPOSE OF SLE SERVICE MANAGEMENT<br />

The purpose of SLE-SM is to standardize and automate, as far as practicable, those<br />

interactions between users and providers of space link and SLE services that are required to<br />

set the values of the parameters of space link and SLE transfer services. In addition, SLE-SM<br />

provides the means to configure the resources needed by the user and provider to execute<br />

those services. In essence, SLE-SM provides a standard way for the user and provider:<br />

a) to set the values of the parameters involved in space link and SLE services;<br />

b) to specify the services needed to execute space link and SLE services;<br />

c) to configure ground stations for the establishment of space links;<br />

d) to configure ground stations for processing of forward and return space link data;<br />

e) to arrange timely provision of transfer services;<br />

f) to disseminate Trajectory Predictions.<br />

CM presents the services performed within the SLE Complex in a standard way to the user,<br />

as defined in detail in the later sections of this document.<br />

The roles of UM and CM, and the SLE-SM services that are set up between them, are<br />

outlined in the following subsections.<br />

2.1.3 SLE UTILIZATION MANAGEMENT<br />

SLE Utilization <strong>Management</strong> is the function within the MDOS that coordinates the requests<br />

by users for space link and SLE services from the SLE Complex.<br />

Utilization <strong>Management</strong> role:<br />

a) Requests periods of provision of space link services and space link extension transfer<br />

services;<br />

b) Provides configuration information for RF, modulation, space link service, and space<br />

link extension transfer service;<br />
