Box 300463, D-53184 Bonn, Germany ROLAND SCHMITZ T-Nova Technology Centre, D-64307 Darmstadt, Germany Keywords: UMTS, MAP Security, Multimedia domain, SIP, IPSec, IKE, Key Management Abstract: This contribution gives a survey of the present standardisation activities by 3GPP (3'd Generation Partnership Project1) in the area of security for signalling in the core network of third generation mobile systems. We give an overview of the protocols that need to be secured, present the basic principles behind the overall security architecture and describe the key management and format of secured messages, as far as they have already been finalised. In particular, we address core network security aspects of the 3GPP multimedia domain. 1 3GPP was formed by regional standards organisations from Europe, Asia and North America to produce specifications for a third generation mobile system named UMTS which is designed to evolve from GSM core network. There is a competing effort known as 3GPP2 with partners from North America and Asia. The original version of this chapter was revised: The copyright line was incorrect. This has been corrected.

University of Oulu, Degree Programme in Wireless Communications Engineering. Master’s Thesis, 63 p. ABSTRACT The global communication network is going through major transformation from conventional to more versatile and diversified network approaches. With the advent of virtualization and cloud technology, information technology (IT) is merging with telecommunications to alter the conventional approaches of traditional proprietary networking techniques. From radio to network and applications, the existing infrastructure lacks several features that we wished to be part of 5th Generation Mobile Networks (5G). Having a support for large number of applications, Internet of Things (IoT) will bring a major evolution by creating a comfortable, flexible and an automated environment for end users. A network having the capability to support radio protocols on top of basic networking protocols, when blended with a platform which can generate IoT use cases, can make the expectations of 5G a reality. Low Power Wide Area Network (LPWAN) technologies can be utilized with other emerging and suitable technologies for IoT applications. To implement a network where all the technologies can be deployed virtually to serve their applications within a single cloud, Network Functions Virtualization (NFV) and Software Defined Network (SDN) is introduced to implement such a networking possibility for upcoming technologies.

Some specific proposals are made that are intended to promote a consistent approach. 1/7 MEC(18)000003r1 1 Introduction There was some discussion at the last face-to-face meeting in Chandler (MEC#12) about the best approach for defining MEC acronyms in the specification documents. This document describes some alternative approaches that could be adopted and makes some specific proposals that are intended to promote a consistent approach across all the Phase 2 specifications and to reduce the burden on anyone making a change to the documents. The MEC-specific and non-MEC specific acronyms are treated separately in clauses 2 and 3. A summary of all the acronyms from all the currently active specifications is shown in the Annex. The changes in Revision r1 reflect the decisions agreed during MEC#88-Tech. 2 MEC-specific acronyms The most problematic definitions are those that MEC is defining for its own use. Some MEC acronyms are defined identically in multiple Phase 1 documents and this is potentially causing inconsistency and could cause maintenance problems if the same approach is used in Phase 2. Hence the first proposal is that all MEC-specific acronyms are only defined in one place.

  • View on 5G Architecture
    5G PPP Architecture Working Group View on 5G Architecture Version 3.0, June 2019 Date: 2019-06-19 Version: 3.0 Dissemination level: Public Consultation Abstract The 5G Architecture Working Group as part of the 5G PPP Initiative is looking at capturing novel trends and key technological enablers for the realization of the 5G architecture. It also targets at presenting in a harmonized way the architectural concepts developed in various projects and initiatives (not limited to 5G PPP projects only) so as to provide a consolidated view on the technical directions for the architecture design in the 5G era. The first version of the white paper was released in July 2016, which captured novel trends and key technological enablers for the realization of the 5G architecture vision along with harmonized architectural concepts from 5G PPP Phase 1 projects and initiatives. Capitalizing on the architectural vision and framework set by the first version of the white paper, the Version 2.0 of the white paper was released in January 2018 and presented the latest findings and analyses of 5G PPP Phase I projects along with the concept evaluations. The work has continued with the 5G PPP Phase II and Phase III projects with special focus on understanding the requirements from vertical industries involved in the projects and then driving the required enhancements of the 5G Architecture able to meet their requirements. The results of the Working Group are now captured in this Version 3.0, which presents the consolidated European view on the architecture design.
