Chapter 6 WiMAX 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. Figure 30 ND&S Scenario NAP-ID = 2 V-NSP NSP-ID = 20 Home NSP NAP-ID = 1 The channel plan settings specify the allowed frequency range to search for a NAP.
