IP Connection
Management
The IP Connection Management package provides services to accommodate
automatic IP connection selection, application-assisted roaming logic, contention
management for IP connections, IP connection monitoring and logging, settings
management for IP connections, UI dialogs related to IP connections and managing
PDP contexts.
- Bearer
Management
The Bearer Management collection offers logic for
selection and re-selection (roaming) of an IP connection, functional implementation
of Mobility API, Contention management and error management related to IP
connection.

Level Roaming
Application-level roaming (ALR) enables your application to roam
to use the best available data connection while operational.

a connection with destination networks
Destination networks, also known as Service Network Access Points
(SNAPs) avoid the connectivity problems that are related to the access point
being fixed for the duration of the data connection. With the availability
of WLAN and other data bearers, the number of access points has grown considerably.
With WLAN, the availability of an access point can change frequently. A
fixed access point in selection often leads to a poor access point choice.
Because the network environment is now more dynamic, you can have either a
safe but slow connection, or a fast but unreliable connection. In practice
this means that the application is either stuck with using GPRS or the user
must continuously change the settings to point to the WLAN access point that
happens to be available. A fixed access point leads to non-optimal usage
of available connections, especially with applications that use long-lasting
data connections.
