Home NSP). Through the NAPs base station, which is identified by a NAP-ID, the subscribers
BM2022 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 subscribers BM2022 cannot reach a base station owned by his Home
NSP (base station with NAP-ID = 1). The BM2022 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 subscribers service agreement specifies to route traffic from the other service
provider to the Home NSP, so the Home NSP authenticates and authorizes the connection.
Figure 23 ND&S Scenario
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.
