Handoff a call from
Voice over Mobile to
Voice over Wi-Fi
- A
BlackBerry Mobile Voice System user has a
BlackBerry device
that is configured to use
Wi-Fi as
the default network and to use the mobile network when the
Wi-Fi network is
unavailable.
- In an area with no
Wi-Fi coverage, the user
makes a
Voice over Mobile call on a
BlackBerry
device.
- The user moves into an area
with
Wi-Fi coverage. One of the
following actions occurs:
- If the template setting
for Network handoff is set to Automatic handoff with user notification, the
BlackBerry
device automatically sends the request to move the
Voice over Mobile call to the
Wi-Fi network. The
user can cancel this action.
- If the template setting
for Network handoff is set to Automatic handoff with user prompt, the
BlackBerry
device prompts the user to confirm the request to move the
Voice over Mobile call to the
Wi-Fi network. If the
user confirms the request, the device moves the
Voice over Mobile call to the
Wi-Fi network.
- The device starts a call
move request. The device compresses and encrypts the request, and sends it to
the
BlackBerry Enterprise Server
over the
Wi-Fi network.
- The
BlackBerry Enterprise Server decrypts and decompresses the request and sends it to
the
MVS BlackBerry Enterprise Server
Connector.
- The
MVS BlackBerry Enterprise Server
Connector sends the request to the
MVS Session
Manager.
- The
MVS Session
Manager establishes a
Wi-Fi call with the
device.
- The device answers the
Wi-Fi call on behalf of
the user.
- The
MVS Session
Manager instructs the
PBX to change the RTP connection from the mobile network to the
Wi-Fi network.
- The PBX switches the mobile
call with the
Wi-Fi call.
- The
MVS Session
Manager disconnects the mobile call, and notifies the device
that the mobile call was moved. The user receives a notification that the
Voice over Mobile call was moved to the
Wi-Fi network.
- The user continues the call
on the device.
