Introducing Device Mobility
Introducing Device Mobility
Cisco CallManager uses IP subnets and device pools that contain location
information to determine a device home location. By linking IP subnets to
locations, the system can determine whether a device is at its home location or a
remote location and register the device accordingly.
To support device mobility, modifications to the device pool structure separate the
user information from the location and mobility information. The device pool now
contains the information that pertains to the device itself and to device mobility.
An added common profile allows you to configure all the user-related
information. You must associate each device with the common profile for user
based information.
In addition to the device pool and common profile, device mobility uses device
mobility groups, physical locations, and device mobility information to determine
device identity and roaming properties and configuration.
This section describes these topics in more detail:
• Device Pool and Common Profile
• Device Mobility Design

pertain to the user.
The Device Pool window contains these parameters:
