Home NSP). Through the NAP’s base station, which is identified by a NAP-ID, the subscriber’s
WiMAX Device can access the Internet through a network service provider (NSP). Access can be
through another network service provider (Visited-Network Service Provider or V-NSP) or his own
network service provider (Home NSP), depending on his service agreement.
In the following scenario, the subscriber’s WiMAX Device cannot reach a base station owned by his
Home NSP (base station with NAP-ID = 1). The WiMAX Device uses ND&S and is able to access
another base station with NAP-ID = 2. This base station is associated with another service provider
(V-NSP with NSP-ID = 20). The subscriber’s service agreement specifies to route traffic from the
other service provider to the Home NSP, so the Home NSP authenticates and authorizes the
connection.

The channel plan settings specify the allowed frequency range to search for a NAP. The channel plan
is necessary to speed up the network discovery process.
