Chapter 19 Cisco CallManager Device Mobility

Introducing Device Mobility

Device Mobility Design

To design an efficient device mobility structure, you must first determine how to divide the network into hierarchical groupings with distinct device mobility properties and make the proper associations among the groupings. This is done using device mobility groups, physical locations, device pools, and subnet-based device mobility information.

Device Mobility Groups

Device mobility groups represent the highest level geographic entities in your network. Depending upon the network size and scope, your device mobility groups could represent countries, regions, states or provinces, cities, or other entities. For example, an enterprise with a worldwide network might choose device mobility groups that represent individual countries, whereas an enterprise with a national or regional network might define device mobility groups that represent states, provinces, or cities.

Movement of a device from one device mobility group to another represents the highest level movement that Cisco CallManager recognizes.

Physical Location

Physical location represents the next division below that of device mobility group. Physical locations provide a means of distinguishing the parameters that relate to a specific geographical location from other parameters. For example, a Music on Hold (MOH) server may serve a specific office or campus within the enterprise. When a device roams to another office or campus and reregisters with

Cisco CallManager, having the device served by the MOH server at the roaming location represents best practice. By defining the physical location according to availability of services such as MOH, you can assure efficient and cost-effective reassignment of services as devices move from one physical location to another. Depending upon the network structure and allocation of services, you can define physical locations based upon city, enterprise campus, or building.
