P800/P802 White Paper, January 2003 61 Area Information Area Information, commonly known as SMS Cell Broadcast, is a method of sending text messages to mobile phones within a certain part of the network. For example, traffic news can be sent to users in a single cell or a group of cells. It is not widely deployed by network operators. Information is organised into numbered channels. The user selects the required channels in the P800 Control Panel, Messaging Accounts, CBS tab. The requested text messages are received and placed in the ‘Area info’ mailbox. Cell Information may be switched on and off in the Control Panel. When enabled and supported by the network, the ID of the current cell (or group of cells) will be displayed underneath the network operator name in the FC phone display. This is often the telephone area code or postal code of the current location.
P800/P802 White Paper, January 2003 62 Document Viewer The P800 Viewer application enables the user to manage and view a wide range of document formats. A set of plug-ins is included for common document types and more can be loaded from the Multimedia for P800 CD-ROM. Viewer will list the documents that it finds on Internal and Memory Stick storage. Documents can be opened from the list. Viewer is also automatically started when opening an e-mail attachment, in which case the user can also choose to save the document. Exact options whilst viewing a document depend on the document type. For example, when viewing a Microsoft Word document, draft (text only), Normal (text, tables, graphics) and Page (whole page on the screen) views are available. Text can be copied from the document and pasted into, for example, a Jotter note or an e-mail. Viewer supports a subset of functionality in each case, for example Word headers and footers will not be displayed. Documents can be exchanged using Memory Stick, infrared, Bluetooth wireless technology, MMS and e- mail. When viewing a PDF document, it can be fitted to the width of the screen or to the window. It is also possible to zoom in and out.

P800/P802 White Paper, January 2003 64 Browser, M-Services and MeT The P800 features an integrated browser capable of browsing WAP, Web (HTML) and cHTML content from a common User Interface (UI). M-Services M-Services is a set of feature guidelines published by the GSM Association with the support of leading mobile network operators and handset manufacturers. These include easy start-up for the user, better user experiences, easy download of contents, and simple charging models. Technically, the guidelines cover existing standards including WAP, MMS, EMS, SIM-AT and SyncML. Requirements are also made in the areas of UI, MIME descriptors, media formats and codecs. For developers and operators, this means that a standardised yet rich set of services can be deployed simply. Users will be able to enjoy a new world of consistently available and advanced mobile internet services such as: • Pictures • Wallpapers • Screensavers • Audio / Ring signals • Games The P800’s large colour touch-screen, dedicated browser access button and large amount of memory exceed the requirements of M-Services. The UI meets many of the recommendations. Since the P800 has a proper filing system for storage of media, download content is typically stored to file such that it is available to many applications including the P800’s personalisation settings. The P800 supports both WAP Provisioning and the established Ericsson/Nokia OTA provisioning standards – see Personalisation and Customisation section for more details. MeT – Mobile electronic Transactions With the introduction of WAP it has become possible to access mobile Internet services and undertake mobile e-commerce transactions. One of the key elements is the ability for any phone to operate with any service in this mobile e-commerce environment. This is why Sony Ericsson, Motorola, Nokia, Panasonic, NEC, Siemens and others have teamed together to create a common industry framework for mobile commerce - the Mobile electronic Transactions (MeT) initiative. Members come from handset manufacturers, financial institutes, mobile operators, security specialists and technology /solutions vendors. The MeT initiative co-operates with MasterCard International’s Global Mobile Commerce Forum. MeT has the aim of establishing a framework for secure mobile transactions, ensuring a consistent user experience independent of device, service and network. It is a global initiative to ensure that interoperable mobile transaction solutions are developed around the world - enabling consumers to access goods and services seamlessly wherever they may be. MeT builds upon existing industry standards such as WAP, WTLS, WIM and WPKI.
P800/P802 White Paper, January 2003 65 MeT covers the following core functions: Initiation Providing the Personal Trusted Device (PTD) with key pairs for authentication and signing. Registration Providing the PTD with certificates associated with its keys. Secure Connection Establish an encrypted link with the server in order to keep information private. User Authentication Prove the identity of an individual or an application. Digital Signatures Authorise a contract by means of a user signing text (see example below) The P800 fulfils the compliance requirements for MeT version 1.0, (February 2001), according to the following MeT specifications: • Met Core Specification • MeT PTD Security Requirements • MeT CUE Consistent User Experience More information on MeT may be found at http://www.mobiletransaction.org/ MeT Example Whilst shopping around for a new television set, the user finds a good price from a store and decides to order immediately. The store requests a ‘signed text’ confirmation from the customer: As with many online transactions, the user enters all the details and must then press OK to confirm the transaction. The user is requested to sign the transaction using a suitable certificate. The certificate has a related signature PIN. The user enters the PIN to confirm the transaction.
P800/P802 White Paper, January 2003 66 P800 Browser Content Types Supported The P800 browser, called “Internet,” supports all of the following content types within a single browser, directly or via a gateway/proxy. World Wide Web (WWW) - HTML The WWW is the most popular method of publishing information on the internet and on company intranets. Content is organised using the Hypertext Markup Language (HTML). The P800 browser can read HTML pages and therefore gives access to a vast amount of existing material. Of course, much of the content on the WWW is aimed at large screens and will therefore require scrolling on the P800. However some websites, and more frequently those of interest to the mobile user, have ‘low graphics’ or ‘mobile friendly’ options which are better suited to small screens. HTML 3.2 is supported, minus some features that are applicable to large screen devices such as PCs. The main points to note are that the P800 browser does not support Frames or Javascript Wireless Application Protocol (WAP) - WML WAP uses Wireless Markup Language (WML), which is like HTML but specially optimised for mobile devices. The P800 browser is compliant with WML 1.3 and therefore gives access to a world of existing WAP content. The large touch screen and multiple WAP accounts make it easy to access and surf WAP pages Wireless Application Protocol (WAP) 2.0 – xHTML Extensible Hypertext Markup Language, xHTML, is a combination of HTML 4.0 and XML, managed by the World Wide Web Consortium. xHTML Basic provides a common subset of features to enable the design of pages that will work on small handheld devices, yet rich enough for content authoring. In WAP 2.0, xHTML Basic is extended with additional markups to create xHTML Mobile Profile. This is the core markup language for WAP 2.0. WAP 2.0 introduces many new facilities including colour graphics, animation, large file downloading and improved menu handling. The P800 browser supports xHTML Mobile Profile. cHTML Compact HTML is a version of HTML optimised for small handheld devices. It is widely used in Japan. The P800 browser will display cHTML content where it is available on the internet or from mobile operators over GSM/GPRS.
P800/P802 White Paper, January 2003 67 Browser UI The browser is always close at hand, having a dedicated hardware button. It may also be reached from the application picker and the application launcher. The browser is used in FO mode. The touch screen makes navigation very quick and simple – just tap a bookmark or a link to navigate. The Jog Dial can also be used to scroll the page. To work with an object on a page, such as an image, tap and hold it. A menu will be displayed listing available options such as Save, Copy, Send As. To open a new URL, click Internet and select Open Page. Local HTML content can be browsed, for example from the Memory Stick: file:///d:/Media%20files/document/menu/menu.htm Bookmarks and other information is presented in a simple list view. Just tap the text of a bookmark to view the page. Tap the icon to view the bookmark details. As in the R380, WAP Accounts may be stored in a bookmark, ensuring that the correct WAP/internet service provider is used to access the required page. Pages may be saved to local storage. They are kept in the bookmarks list and may be opened offline. WAP Push messages are received within the browser and presented in the list view. The user may organise bookmarks into user-defined folders, for example creating a folder of sports bookmarks and a folder of transport bookmarks. It is also possible to view a list of all signed documents (see MeT example above) and access incoming WAP Push messages.
P800/P802 White Paper, January 2003 68 Browser Security World Wide Web The P800 supports the TLS/SSL to provide a secure encrypted link between the browser and the website. This method is commonly used for secure transactions on the WWW. An icon in the display indicates when a secure connection is in use. WAP Security When using certain WAP services the user may want a secure connection between the phone and the WAP gateway, for example when using banking services. An icon in the display indicates when a secure connection is used. The P800 is based on the WAP 2.0 specifications where security functionality is specified with a technology called Wireless Transport Layer Security (WTLS) and WAP TLS Profile.. The WAP protocols that handle the connection, its transport and its security are structured in protocol layers. The security is handled by the WTLS layer operating above the transport protocol layer. There are 3 WTLS classes that define the levels of security for a WTLS connection: • WTLS class 1 involves encryption with no authentication. • WTLS class 2 involves encryption with server authentication. • WTLS class 3 involves encryption with both server and client authentication Server authentication Requires a server certificate stored at the server side and a root certificate stored at the client side. Client authentication Requires a client certificate stored at the client side and a trusted certificate stored at the server side. A Wireless Identity Module (WIM) can contain both trusted and client certificates, private keys and algorithms needed for WTLS handshaking, encryption/decryption and signature generation. The WIM module can be placed on a SIM card and will then be referred to as a SWIM card. Certificates To use secure connections, the user needs to have certificates saved in the phone. User certificates can be downloaded. There are two types of certificates: Certificate authority A certificate used to verify that a WAP site is genuine. If the phone has a stored certificate of a certain type, it means the user can trust all WAP gateways which present a certificate that can be verified by the trusted certificate. Certificates can be preinstalled in the phone, pre-installed in the SWIM, or downloaded from the trusted supplier’s WAP page. User certificate A personal certificate that verifies the user’s identity. A bank that the user has a contract with may issue this kind of certificate. User certificates can be pre-installed in the SWIM card. The P800 is loaded with WTLS/X509 certificates from Baltimore, CTE Cybertrust, Entrust, GlobalSign and VeriSign.
P800/P802 White Paper, January 2003 69 WIM Locks (PIN Codes) There are two types of WAP security locks (PIN codes) for the WIM on SIM. The locks protect the subscription from unauthorized use when browsing. The locks should typically be supplied from the supplier of the SWIM. Access lock An access lock protects the data in the WIM. The user is asked to enter the PIN code the first time the SWIM card is accessed when establishing a connection. Signature lock A signature lock is used for confirming transactions - like a digital signature. Push Services These are useful for sending updated WAP site contents or WAP links to mobile users. Examples of services that can be implemented using push services: • Notifications about new E-Mails, voice mails, etc. Instant messaging and chat • News, sport results, weather forecasts, financial information (stock quotes etc.) • Personal Information Manager (PIM) - delivery of contacts, meeting requests etc. • Interactive games, e.g. play poker with a friend There are two different forms of Push services, Service Indication and Service Loading. Reception of push messages and automatic load of URL (see below) may be turned on and off in the P800 user preference settings. Service Indication (SI) A Service Indication message contains a short text message and a URL. In the P800, these types of messages are typically stored in the WAP messages inbox which is integrated with the bookmark list in the browser application. When the user opens a message, both the text message and the URL will be displayed. The user have the options to postpone the message, load the URL or to delete the message. Service Loading (SL) A Service Loading message contains a URL. When such a message is sent to the P800, the URL will automatically be loaded into the browser application if the user is currently browsing the same site; otherwise it will be treated as a Service Indication message. Opera Browser Opera Software produces a fast standards-compliant browser for multiple platforms including UIQ. The Opera browser supports frames, javascript, plug-ins and much more whilst having a very compact code size. Opera has developed a technology called Small Screen Rendering which reformats full websites to fit the small screens of mobile devices without the need for scrolling. This technology resides in the browser and does not depend on any additional server capability in the network. Opera has demonstrated this technology on the P800 and is currently porting it to UIQ.

P800/P802 White Paper, January 2003 70 Symbian OS Operating System Symbian is the company that developed the Symbian OS technology. Symbian OS is the operating system for Wireless Information Devices, and can be found in a wide range of PDA, ‘communicator’ and ‘smartphone’ designs. The Symbian OS technology delivers application and communication capabilities in a small package - it has a robust system kernel, powerful object- oriented middleware, industry-standard communication protocol suites, and an optimised implementation of Suns Java TM language. Symbian OS is the largest-selling operating system for smartphones and communicators. The P800 is based on Symbian OS v7.0 and the established UIQ UI. Sony Ericsson and Symbian have been actively working with software developers for some time, and a range of UIQ-based applications have already been publicly demonstrated. Sony Ericsson is also an active participant in developer events such as the Symbian Developer Conference and Java One. Third party applications may make use of the communications, display and storage facilities of the P800. Such applications may therefore be much more powerful than browser-based applications, enabling games to be faster and more exciting, for example. Applications from other PDA OSs and from the PC world may be expected to be ported across to the P800. Applications already available for Symbian OS (for example, on Psion products) may be ported by the supplier to run on the P800. The P800 supports Java-based applications. Java technology is platform-independent, portable, modular and secure. Java applications are easy to develop, deploy and maintain. Because it supports both PersonalJava TM and J2ME CLDC/MIDP (see next page), the P800 is ready to run many applications written for handheld computers and mobile phones. The P800 has 12 Mbyte user data space in which settings, user data and third party applications are stored. (9Mbyte on the P802). Applications are easily downloaded directly to the P800 using the browser, or may be installed from a connected PC. Key consumer applications for the consumer include games, instant messaging, chat, information and entertainment. Corporate applications may be deployed, extending information access to the P800. Open Environment Applications may be written in both C++ and Java. Supported Java environments are PersonalJavaTM and J2ME CLDC/MIDP, both of which are optimised for quick start-up time. C++ C++ is the most comprehensive and flexible programming environment, which enables rich applications to developed. C++ applications will run faster than those written in Java.
