Description / Abstract: 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.
