1.7.7 Lease mode scenario
In the example below there are a total of four forward bearers and
three return bearers a beam. One forward and one return bearer is
used by public users. The remaining bearers in the beam are used
by two separate lease groups. The FleetBroadband Terminals
belonging to the separate lease groups have exclusive use of their
bearers and do not share capacity with members of other lease
groups or with the public users.
Lease Mode allows organisations to procure satellite capacity
in a cost effi cient fashion. Within the lease group the capacity is
shared and managed using the standard BGAN radio resource
mechanisms but the lease capacity is available to the lease group
members alone. It is as if the lease group members have access
to a separate BGAN network exclusively for their use.
If leased capacity becomes too congested to admit new
connections in a beam but capacity is still available to the public
users then lease group members will be admitted to the public
bearers. Conversely, public users will not be permitted to use the
lease capacity if public bearers are heavily congested.
