With recent technology advancements mobility support is one of the major needed parameters by any wireless or mobile networks. Continuous mobile movement from one cell to another or from one network to another requires continuous mobility support. Previously, tunneling protocols employment was the technique to support UE's inter or intra network mobility. More specifically, GRE, GTP, MIPv6 or PMIPv6 were employed for mobility support. In tunneling encapsulation of one protocol over another protocol is performed to deliver IP packet during inter network or intra network handover. In terms of usage scenario of each tunneling protocol, tunnel establishment, data transfer and tunnel release, an overview and comparison of tunneling protocols is presented in this paper. 3GPP and WLAN interworking, and GAN based usage scenarios and supported tunneling mechanisms has been discussed. Some insights regarding security, multiplexing, multiprotocol and packet sequencing support are also provided for each tunneling protocol.

“…We foresee that a LTE-like network will be deployed for the next generation of civil security networks. This paper carries on the attempt in [1] to optimize the handover procedure in a hybrid satellite and terrestrial LTE architecture. A LTE network solution that meets the civil security requirements has been designed by adding a satellite component to the common terrestrial architecture as in [2].…”

Long Term Evolution tends to become the next generation of civil security networks. In order to meet the safety user requirements, preference is given to an integrated satellite and terrestrial architecture. It provides a widespread connectivity built on the large satellite coverage. In this paper, we focus our works on the real behavior of TCP protocols, implemented in on-the-shelf devices, during a handover within the hybrid architecture. We aim to improve an optimized handover procedure by taking into account the real implementations that differ from simulation tools and RFCs. In order to highlight and solve the problematic behaviors of TCP protocol due to a S1 handover with an SGW and MME relocation, a test is set up with Linux virtual machines for TCP application linked to a NS3 LTE network simulatior.

“…To evaluate PPDR use cases over a convergent satellite-terrestrial architecture and to support the 3GPP and the European standardization efforts, practical realizations of 4G testbeds [6][7][8] and 5G testbeds 9,10 have been promoted. These testbeds are pioneering new concepts, and they provide a platform to evaluate SATCOM-enabled PPDR use cases.…”

Summary A secure and flexible communication infrastructure for the use of broadband and IP‐based services is becoming more and more important in the context of Public Protection and Disaster Relief (PPDR). Government agencies and emergency responders need to be able to react quickly to emergencies across the globe. In particular, satellite‐based 5G mobile networks can support government agencies during their critical tasks. To support the standardization committees and the industry, it is required to evaluate new architectures for such networks by utilizing testbeds and field trials. In this article, we propose and investigate architectures for mobile PPDR networks with satellite backhaul to ensure Communication on‐the‐Move. The flexibility within the architectures comes with the distribution of the core network nodes at the edge of the network applying the Core‐Edge Split concept. The presented results show that already existing interfaces of the Evolved Packet Core 3GPP standard allow satellite‐based 5G networks tailored to the needs of government authorities.
