White Paper T310/T312
20 January 2003
Manual configuration is done using the menu
system in the phone. This is described in the User’s
guide.
Over-the-air provisioning
of WAP settings
To simplify the configuration of WAP settings in the
T310/T312, all settings can be sent to the phone as
an SMS message. This makes it easy for an
operator, a service provider or a company to
distribute settings for Internet/intranet, and WAP,
without the user having to configure the phone
manually. This also makes it easy to upgrade
services, as no manual configuration is required.
• The OTA configuration message is distributed
via SMS point-to-point.
• The setup information is a binary encoded XML
message (WBXML). To receive information
about OTA specifications, please contact your
local Sony Ericsson representative for con-
sumer products. A configurator that utilizes OTA
provisioning can be tested on www.SonyErics-
son.com.
• The user is alerted about new settings when the
ongoing browsing session ends. Settings are
not changed during an ongoing browsing ses-
sion.
• User interaction is limited to receiving and
accepting/rejecting the configuration message,
and selecting which WAP profile to allocate the
settings to.
• Security can be handled using a keyword identi-
fier displayed on the screen as a shared secret
between the SMS sender and recipient. It is
important that the user can verify that the con-
figuration message is authentic.
Push services
Examples of WAP services that can be pushed
include:
• Notification of new e-mail, voice mail, etc.
• News, sports results, weather forecasts, finan-
cial information (stock quotes etc.).
• Personal Information Manager (PIM) - delivery
of contacts, meeting requests etc.
• Smart card e-cash.
• Interactive games.
In the T310/T312, the user selects whether to allow
push messages or not. There are two different
forms of Push services:
Service Indication (SI)
An SI service sends to the browser a text message
with a URL of a WAP page. If the user decides to
load the URL, normal WAP browsing commences.
When an SI is received by the T310/T312, the user
can load it immediately, postpone it or delete it.
Received SIs are stored in the Push Inbox and can
be viewed and loaded at a later time. The Push
Inbox displays a list containing the first part of each
received message. The list is sorted by action
attribute (high/medium/low) or reception time of the
message.
Service Loading (SL)
An SL service sends and displays a WAP page if
accepted by the user. If the SL is not accepted, it is
loaded and stored in the cache for later use. The
user can start the browser and load the page from
the cache manually.
