White Paper T630/T628

Direct Links

There are direct links in the menu system for easy download of e.g. pictures and melodies from WAP sites.

Sending bookmarks

WAP 2.0 enables the sending of bookmarks via infrared as well as via SMS.

Push services

Businesses and service providers can “push” con- tent or service indications to work groups and/or customers. Examples of pushed content would be mail alerts, messaging, news, stock quotes, con- tacts, meeting requests, etc.

Provide settings

Using SMS messages, configuration settings can be sent over the air, OTA, so that the user does not need to configure the WAP access settings manu- ally. WAP settings may also be customized by the operator.

Support of XHTML

The WAP browser supports the markup languages of WAP 2.0. It supports WAP 1.2.1 + XHTML Mobile Profile 1.0 + WCSS (XHTML-MP), XHTML Basic, a subset of XHTML-MP, IHTML, WAP Cas- cading Style Sheets (WCSS), WML version 1.3 and WMLScript. The subsets of the WAP standard XHTML are supported by all major WAP browsers. WAP pages authored in XHTML and WCSS can be displayed in standard PC browsers such as IE and Netscape. WAP pages authored in WML can be displayed in WAP browsers only. It is preferable, therefore, that developers use XHTML and CSS to develop content as these are pure WAP standards. WML and WMLScript are for backwards compati- bility.

All of the basic XHTML and IHTML features are supported, including text, images, links, check- boxes, radio buttons, text areas, headings, hori- zontal rules and lists. For IHTML also blink and marquee, but not tables.

Adapt to phone type

The User Agent Profile function allows WAP con- tent to be automatically optimized for the T630/ T628, ensuring the intended user experience.

Several bearer types

The T630/T628 accesses the WAP over a standard GSM Data connection as well as over a GPRS con- nection (network-dependent services.)

Bandwidth efficiency

Unlike traditional Internet services, WAP services are relayed to wireless devices as binary encoded data, maximizing bandwidth efficiency. A GPRS connection further increases efficiency.

Easy create for WAP

Creating a WAP service is no harder than creating an Internet/intranet service, as WML and WMLS- cript are based on well-known Internet languages such as HTML and JavaScript.

Support for cookies

T630/T628 has support for cookies (client based), an application used by WAP sites to store site-spe- cific information in the browser between visits to the site. Cookies give the site owner a possibility to see when a person has visited their site. They also save the user from having to enter the same infor- mation (e.g. the password or user ID) more than once. Cookies are often used by e-commerce sites (shopping carts and wish lists).

Style sheets

T630/T628 supports style sheets offering content developers more control over the way their WAP pages are displayed.

Using standard tools

Service creators can use standard tools such as ASP (Active Server Page) or CGI (Common Gate- way Interface) to generate content dynamically.

Services can be created once and then made accessible on a broad range of wireless networks.

Maintain customer base

Existing services can be adapted to WAP. The nec- essary binary encoding is handled by a WAP Gate- way, allowing HTML-based services to be viewed on the WAP browser of the T630/T628. An XHTML page can be viewed in both the WAP browser and in any standard Web (HTML) browser.
