are analogous to and must interoperate with the server and
client device roles that GOEP defines.
 Usage Scenarios
 An example scenario would be the exchange of a contact or
appointment between two mobile phones, or a mobile phone and a
PC.

ALERT NOTIFICATION PROFILE
[ANP]
 The Alert Notification Profile (ANP) enables a client device to
receive different types of alerts and event information, as well as
information on the count of new alerts and unread items, which
exist in the server device.
 Usage Scenarios
 The Alert Notification profile allows a device like a watch to obtain
information from a cell phone about incoming calls, missed calls and
SMS/MMS messages.The information may include the caller ID for
an incoming call or the sender's ID for email/SMS/MMS but not the
message.This profile also enables the client device to get
information about the number of unread messages on the server
device.

connect and interact with a Heart Rate Sensor for use in fitness
applications.
 Usage Scenarios
 The Heart Rate Profile allows heart rate information to be sent from
one sensor (heart rate monitor) to another device, such as at a
doctor's office. A nurse or doctor could take a patient's heart rater
and have that information automatically uploaded to the patients
file.

PROXIMITY PROFILE [PXP]
 The Proximity profile (PXP) enables proximity monitoring
between two devices.
 Usage Scenarios
The Proximity profile defines the behavior when a device moves away
from a paired device so that the connection is dropped or the path loss
increases above a preset level, causing an immediate alert.This alert can
be used to notify the user that the devices have become separated. As a
consequence of this alert, a device may take further action, for example
to lock one of the devices so that it is no longer usable.
