Mobile communication systems are becoming more and more complex to design (by researchers), operate (by the operators) and used by the people in the street. Mobile users now wish to be always connected, irrespective of time and place, and have access to a range of new services to help him/her in everyday life, all at the lowest possible cost. Currently no one knows how to evaluate whether a system is efficient or not in such provision. The reason for this is the huge number of parameters involved which collectively influence system efficiency. So far the practice has been to use a subset of such parameters to define localised efficiency -- but this does not provide overall efficiency and it will not lead to low cost or optimum use of scare spectrum. There are three important criteria which need to be considered and designed together to achieve a highly efficient mobile system. These are: quality of offered service, capacity and the cost of the system. Each of these criteria are influenced by a large number of parameters individually, where each have different weightings. Optimum design needs to find a fine balance between the three different criteria and yet currently there is no technique available which enables them to be optimised together to provide the required low cost solution. What makes this difficult is that a mobile system is dynamic by nature in terms of: range of mobility of users, wide range of operational environments, wide range of services with different bit rates and expected qualities, etc. This all points to requirements for a system with a certain degree of adaptability so that the system can self-organise and adapt itself to changing conditions. Currently systems are designed and operated on more or less fixed technique and parameters. These include the design of air-interface, media access control, handover algorithms, cell sizes and fixed frequency band allocation which all lead to wastage of resources and expensive solutions. The mobile systems of the future, addressed herein, are continuously adaptable and reconfigurable and respond automatically to the conditions of environments and user demands. It is only by engaging with these factors that efficiency can be maximised and the required low cost new services can be delivered to users. The challenge of the research described herein is how to collectively design such very complex networks so that users, service providers and network operators will all consider it efficient and cost effective to participate in the mobile vision of the future.

移动的通信系统的设计（由研究人员）、操作（由运营商）和由街上的人们使用正变得越来越复杂。移动的用户现在希望随时随地保持连接，并能够以尽可能低的成本获得一系列新服务，以帮助他/她在日常生活中发挥作用。目前，没有人知道如何评价一个制度是否有效，在这种规定。其原因是涉及大量参数，这些参数共同影响系统效率。到目前为止，实践一直是使用这些参数的子集来定义局部效率-但这并不提供整体效率，也不会导致低成本或最佳使用稀缺频谱。为了实现高效的移动的系统，需要考虑和设计三个重要的标准。这些因素是：所提供服务的质量、能力和系统的成本。这些标准中的每一个都受到大量参数的单独影响，其中每一个都有不同的权重。最佳设计需要在这三个不同的标准之间找到一个很好的平衡，但目前还没有技术可以使它们一起优化，以提供所需的低成本解决方案。使这一点变得困难的是，移动的系统在以下方面本质上是动态的：用户的移动性范围、操作环境的宽范围、具有不同比特率和期望质量的宽范围的服务等。这都指向对具有一定程度的适应性的系统的要求，使得系统可以自组织并使其自身适应变化的条件。目前，系统的设计和操作或多或少是固定的技术和参数。这些问题包括空中接口设计、媒体接入控制、切换算法、小区大小和固定频带分配，这些问题都导致资源浪费和昂贵的解决方案。本文所述的未来的移动的系统是连续可适应和可重新配置的，并且自动响应环境条件和用户需求。只有充分考虑这些因素，才能最大限度地提高效率，并向用户提供所需的低成本新服务。这里描述的研究的挑战是如何共同设计这样的非常复杂的网络，使得用户、服务提供商和网络运营商都将认为参与未来的移动的愿景是高效和成本有效的。
