Session API
***********
Connection management algorithm basics
======================================
When a session is created, a sorted list of services is added to the
session. The services are filtered and stable sorted according
following rules:
- AllowedBearers (filter and sort)
- RoamingPolicy (filter and sort)
A stable sorting algorithms maintains the relative order.
If a service is removed or added all sessions are updated according
the above rules.
There are three triggers which lead to evaluate the connect
algorithm:
- Session.Connect()
- PeriodicConnect
- Offline
Connect algorithm:
Session.Connect() Offline
PeriodicConnect |
| Yes +------+-------+ No
+------+StayConnected?+------ Do nothing
| +--------------+
Session.Change() ------+
|
+------+-------+
+-----+EmergencyCall?+-----+
Yes| +--------------+ |No
| |
Connect to +--------------+
first available +---+AvoidHandover?+---+
Service | +--------------+ |
Yes| |No
+----------------+ |
+---+In service_list +---+ |
Yes| |and online? | |No |
| +----------------+ | |
| | |
Take that one Take first in
the service list
There are two triggers which lead to evaluate the disconnect
algorithm
- Session.Disconnect()
- IdleTimeout
Disconnect algorithm:
Session.Disconnect()
IdleTimeout
|
+--- Session.Change()
|
+-----------------+ Yes
|service not used +-------------+
|by other session?| |
+------.----------+ |
|No |
| |
Service.Disconnect() Do nothing
