subscription from unauthorised use when browsing. The locks should typically be supplied from the supplier
of the SWIM.

Signature lock

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 are:
•
Notifications about new E-Mails, voice mails etc
•
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 P900 user preference
settings.
Service Indication (SI)
A Service Indication message contains a short text message and a URL. In the P900, 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 has 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 P900, 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.
SWIM, or downloaded from the trusted supplier's WAP page.
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.
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.
A signature lock is used for confirming transactions - like a digital signature.
