Issues for the integration of satellite and terrestrial cellular networks for mobile communications
Abstract
Satellite and terrestrial cellular systems naturally complement each other for land mobile communications, even though the present systems have been developed independently. The main advantages of the integrated system are a faster wide area coverage, a better management of traffic overload, an extension to geographical areas not covered by the terrestrial network and, in perspective, the provision of only one integrated system for all mobile communications (Land/Aeronautical/Maritime). To achieve these goals, as far as possible the same protocols of the terrestrial network should be used also for the satellite network. This paper discusses the main issues arising from the requirements of the integrated system, illustrates some preliminary results and presents possible improvements for the technical solutions.
... The first approach considers the satellite system as an extension of the GSM network and satellite beams as GSM cells, not only from the architectural viewpoint but also from the operative one: this means that traffic channels, disregarding cellular or satellite, are allocated according to level and quality of the received signal. It has been already shown [4] that this choice leads to a poor network efficiency. ...
This paper aims to depict some basic concepts related to the definition of an integrated system for mobile communications, consisting of a satellite network and a terrestrial cellular network. In particular three aspects are discussed: (1) architecture definition for the satellite network; (2) assignment strategy of the satellite channels; and (3) definition of 'internetworking procedures' between cellular and satellite network, according to the selected architecture and the satellite channel assignment strategy.

Satellite communications were also in focus with the proposals for providing messaging and low bandwidth data services to remote communities or defence forces [28] [29] [97] [156] . Research was being carried out into the creation of efficient protocols for data transfer over radio links. ...

After a survey on the historical reasons for the current
configuration of incompatible terrestrial and satellite mobile networks,
the paper compares the classical traffic channel assignment in cellular
networks with a more enhanced strategy, suitable to an integrated
configuration that exploits the concept of sharing, peculiar to
satellite resources. The impact on network management and planning is
pointed out and the results of a simulation model allow a quantitative
assessment. The paper also illustrates how the corresponding procedures
respect the terrestrial cellular network protocols
A network architecture, featuring a number of mobile packet radio
subnetworks interconnected through a broadband backbone network
infrastructure, is introduced. A number of issues related to this
architecture are identified and briefly discussed. Specifically, the
authors discuss the issues of subnetwork formation, stand-alone and
interconnected operation, narrowband-to-broadband internetworking, media
independence of gateways, and the issue of handling inter-network
mobility of nodes. They attempt to show that consideration of these
issues leads to a concept of integrated, mixed-media communications.
They also present a number of research directions (and projects)
resulting from the `interconnected narrowband networks' approach
In an integrated cellular/satellite system for mobile
communications a satellite subsystem cooperates with a terrestrial
cellular network for providing user services. The paper addresses the
problems related of the reuse of the procedures of the GSM cellular
standard in an integrated system. Allowing at most changes only at the
mobile terminal and/or in the satellite network. The results of the
study show that most of the GSM procedures can be reused in an
integrated system (in a few cases with limited protocol variations) but
some others would require modifications to the cellular network. The
results of this study shall also be useful for the suitable definition
of the protocols of an integrated satellite/terrestrial system for the
next generation of mobile and personal communication services
