5.BT research for Linux-based mobile devices
5.1 Previous CTAA research activity
The convergent terminals and applications (CTAA) research
theme,within BT’s Research and Venturing organisation,
investigates emerging trends in the entire device ecosystem
— including components,hardware and software issues for
future mobile devices,as enablers for future service
offerings.Previous activities within the CTAA research theme
have involved the development of proof of concept (PoC)
demonstrators for innovative service concepts using mobile
devices running Symbian or Windows OSs.Application/
service development on mobile devices requires access to
software development kits (SDKs) which are usually
obtained by subscribing to appropriate developer programs,
e.g.Symbian Developer Program,Microsoft Developer
Network,etc,related to the device OS.
5.2 Enablers for Linux-based mobile device
research
New challenges are presented when pursuing similar
research activities for Linux-based mobile devices.There is
no such thing as a single standard Linux OS (let alone one for
mobile devices),only a large number of different Linux
distributions.Many ODM/OEMs appear to have chosen
commercially available embedded Linux distributions for
their mobile handset products.Some ODMs/OEMs have
used their own Linux distributions developed in-house.A
number of different commercially available application
framework SDKs can be chosen in conjunction with a
number of different (embedded) Linux distributions,leading
to a confusingly rich set of possible configurations.
Such research activity naturally requires the availability
of a number of mobile phone devices (or failing that a
developer’s reference design implementation) running an
embedded Linux distribution.To investigate FMC service
scenarios dual-mode (GSM and Wi-Fi equipped) mobile
devices are a must.The mobile device OS needs to have
some basic initial capabilities,for example to be able to
make GSM phone calls,have driver support for a Wi-Fi
interface and support a basic set of applications.
Additionally the mobile device needs to be ‘open’ rather
than ‘locked-down’,
so that new applications can be
programmed and loaded on to the device.This may require
special co-operation from a device manufacturer or mobile
phone chipset manufacturer.An off-the-shelf,Linux-based,
mobile device is likely to be locked down for reasons of
device stability or even legality.Software requirements
include an SDK from the mobile device manufacturer which
includes cross-compilation tools,debuggers,etc,plus a
means to load new applications on to the device.
Furthermore,the SDK should include reusable component
libraries which support application development,e.g.GUI,
multimedia capabilities,SIP stack,codecs.

5.1过去的CTAA研究活动
BT研究及投资机构就收敛终端和应用程序的课题进行了研究,他们调查了整个设备系统发展的新趋势,包括未来移动设备的组成、硬件和软件,为未来的服务提供作准备.CTAA研究之前的活动包括POC应用的进展.通过塞班和微软操作系统运行的移动设备,他们为这一创新性服务概念作出了展示.移动设备服务的应用程序和服务的发展需要软件工具开发包（SDKs）,这一开发包通常要通过签署相应的开发者计划得到.比如,有关于操作系统的塞班开发者计划,微软开发者支持网站等.
5.2基于Linux移动设备的研究的前提
当研究人员为基于Linux的移动设备进行类似的研究时,他们遇到了新的挑战.根本没有单独标准的Linux操作系统这一说法（更别提为移动设备了）,只有一大堆不同发行版本的Linux系统.许多原始设备制造商（ODM/OEMs）似乎已经为他们的移动手持产品选择了可嵌入式的Linux发行版.其中一些还使用了他们自己开发的Linux发行版本.由于有一大堆不同的Linux发行版,与之对应的使得许许多多不同的应用程序开发包面世,导致各种不同的配置产生.这样一来,他们的研究活动就需要许多移动电话设备来运行嵌入的Linux开发版本（或者宣告开发者参考设计的失败）.要研究FMC服务的双模式（GSM和Wi-Fi模式）方案,移动设备时不可缺少的.移动设备操作系统需要具备几倍的功能,比如能够进行GSM通话,有驱动程序支持Wi-Fi界面和支持一套基本的应用程序.除此之外,移动设备还需要是开放的而不是固定不变的.
