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. For further information visit http://www.opera.com/
