Over The Air provisioning of
WAP settings
To simplify configuring WAP setting in a number of
phones, all settings can be sent as an SMS mes-
sage to each phone. This makes it easy for an
operator, a service provider or a company to dis-
tribute settings for Internet/Intranet, and WAP,
without having to configure each phone manually.
This also makes it easy to upgrade the services
provided to the users, without the need for users
to perform any manual configuration.
• The OTA configuration message is distributed
via SMS point-to-point.
• The setup information is a binary encoded
XML message. To receive information about
OTA specifications, please contact your local
Sony Ericsson representative for consumer
products.
• The user is not alerted about new settings
until the ongoing browsing session ends. Fur-
thermore, settings are not charged during an
ongoing browsing session.
• The necessary user interaction is limited to
receiving and accepting/rejecting the configu-
ration message, and selecting which WAP
profile to allocate the settings to.
• Security can be handled using a keyword
identifier displayed on the screen as a shared
secret between the SMS sender and the
receiver. It is important that the user has a
way to verify that the configuration message
is authentic.
Configuration of WAP
settings
To perform the WAP configuration of a single
phone it is suggested to use the functions and
information provided on the Sony Ericsson home-
page at http://www.SonyEricsson.com/.
A manual configuration is made using the menu
system in the phone. This is described in the
User’s Guide.
