Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical
activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the
work. In the field of information technology, ISO and IEC have established a joint technical committee,
ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the national bodies
casting a vote.
In exceptional circumstances, when the joint technical committee has collected data of a different kind
from that which is normally published as an International Standard (“state of the art”, for example), it
may decide to publish a Technical Report. A Technical Report is entirely informative in nature and shall
be subject to review every five years in the same manner as an International Standard.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO/IEC TR 29181-4 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 6, Telecommunications and information exchange between systems.
ISO/IEC TR 29181 consists of the following parts, under the general title Information technology —
Future Network — Problem statement and requirements:
— Part 1: Overall aspects
— Part 2: Naming and addressing

Introduction
This part of ISO/IEC TR 29181 (Future Network: Problem Statement and Requirements) describes the
problems of the current network and the requirements for Future Network in the mobility perspective.
The general description on the problem statement and requirements for Future Network is given in
ISO/IEC TR 29181-1. In addition, ISO/IEC TR 29181-4 establishes the problem statement and requirements
for Future Network from the viewpoint of architecture and functionality for mobility support.
In general, the mobility issues can be classified into link-layer, network-layer, and transport/application
layer mobility management. It is noted that the link-layer mobility issues have been addressed and well
defined in the relevant SDOs, such as 3GPPs, IEEE 802, etc. The transport/application layer mobility
issues are also associated with the particular transport/application protocols used by mobile nodes.
On the other hand, the network layer mobility control issues are quite dependent on the network
architecture. Accordingly, this part of ISO/IEC TR 29181 will focus on the mobility issues of Future
Network in the network-layer perspective.
This part of ISO/IEC TR 29181 may be applicable to the overall design of Future Network architecture.

5.1 Mobile environment in FN
With an explosive growth of the number of subscribers of 3G/4G cellular systems and also other wireless
data systems such as WiFi and WiMAX, the mobile networks now become the key driver toward the
Future Network (FN). The number of people who surf the network on their phones has doubled since
2006. In near future, there will likely be more mobile and wireless users than wired ones. In addition,
a variety of new types of wireless access networks like ad hoc networks and sensor networks are
emerging, and they will be the major access means to FN.
Figure 1 illustrates the network environment, in which the users or things in FN will benefit from a
variety of access ways to the network anytime, anywhere, and through any interfaces. In particular,
it is expected that ‘mobile’ users/things, rather ‘fixed’ ones, will become more dominant in FN. In this
context, a crucial requirement for FN is to provide seamless services for the mobile users/things through
the mobile-oriented FN.
Figure 1 — Network environment in FN
With a recent trend of network convergence, it is expected that the all kinds of networks will be evolved
or revolved toward a unified network, i.e. ‘mobile-oriented convergence network’ as shown in Figure 2,
including computer or telecommunication networks.

Historically, the computer networks (i. e., Internet) and the telecommunication networks have been
evolved until now, with quite different design philosophy and business purposes. From the perspec
