Introduction
This Part describes the architecture, services and protocols for
managing mobility in a CDPD Network.
One of the unique attributes of the CDPD Network is that Mobile
End Systems (M-ESs) change their subnetwork point of attachment
(SNPA) at will, and thus traditional forms of network connectivity
and routing may not be used because their location (and therefore
the route to reach them) may not be deduced from their network
address.
Mobility management is concerned with the maintenance of a
location information database and routing of Network Protocol Data
Units (NPDUs) based on this information. A closely related function
is that of radio resource management, which is concerned with the
discovery, selection and use of the most optimal radio channel
available to the M-ES.
