Definition of Integrated MSS System

An integrated MSS system is a system employing a satellite component and ground component where the ground component is complementary to the satellite component and operates as and is an integral part of the MSS system. In such systems the ground component is controlled by the satellite resource and network management system. Further, the ground component uses the same portions of MSS frequency band as the associated operational mobile-satellite system.

Key Elements of Integrated MSS Systems

• Integrated MSS Systems employ an integrated MSS and ground infrastructure to deliver end user services.

• The ground component operates as an integral part of the MSS system, and can only be operated in conjunction with, and integral to, its associated MSS system and network.

• The combined MSS/ground system provides an integrated service offering.

• The ground component is controlled by the satellite resource and network management systems.

• The ground component uses the same portions of the frequency bands that are coordinated for its associated MSS system.

Integrated MSS Systems Regulatory Matters

Administrations may consider granting an Integrated System the same status as its MSS component if:

• The Integrated System ground component can only be operated in conjunction with, and integral to, its associated MSS system and network and within the geographical coverage area of the MSS system.

• The ground component is controlled by the satellite resource and network management systems.

• The combined space/ground system can provide an integrated service offering to end users using common handset capable of communicating with either the satellite or the terrestrial transmission path.

• Administrations should review their regulations to ensure the existing types of authorization are suitable for Integrated System.

Protection of other Services and Systems

Administrations should ensure by adopting necessary technical measures in their telecommunication regulatory frameworks that Integrated MSS Systems presented for their approval are designed and operated in a manner that prevents harmful interference to other services operating according to the ITU Radio Regulations for which the host MSS system would be required to protect.

Administrations should apply general service level requirements as a starting point for allowing Integrated MSS Systems in their administrations.

Administrations should ensure that MSS operator developed system level/operational level parameters, based on particular system characteristics, but that may be different from service level protection parameters.

Follow good practices, relevant ITU-R or other criteria (e.g., additional measures adopted by some administrations) to ensure that the introduction of terrestrial operations within Integrated MSS Systems do not cause harmful interference to other services, including, MSS, RNSS, GMDSS and AMS(R)S services.
