To simplify the provisioning of WAP settings to a number of phones, all settings can be sent as
an SMS message to each phone. This makes it easy for an operator, a Service Provider, or a
company to distribute settings for Internet/Intranet, and WAP, without having to manually conÞ-
gure each phone. This also makes it easy to upgrade the services provided to the users, without
the need for users to perform any manual conÞguration.
¥ The OTA conÞguration message is distributed via SMS point-to-point, not Cell Broadcast.
¥ The setup information is a binary encoded message. To receive information about OTA spe-
ciÞcations, please contact your local Ericsson representative for consumer products.
¥ The needed user interaction is limited to receiving and accepting/rejecting the conÞguration
message, and selecting which WAP proÞle to allocate the settings to.
¥ Security can be handled using a keyword identiÞer 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 conÞguration message is authentic.

There are two bearer types, i.e. two ways to access WAP services from the phone, GSM Data or
SMS. Which access type should be used is determined by, for example, the ISP. Typical diffe-
rencies which distinguish the bearer types are listed below.
