Table C1 illustrates the organization of ANDSF database for discovering WiMAX and WiFi networks. The ANDSF database provides the coverage mapping information for WiMAX and WiFi networks based on 3GPP cell identifiers. In this example the UE_Location can be specified either in terms of 3GPP parameters (PLMN + Cell Identifier) or in terms of geo spatial co-ordinates.

Table C1: ANDSF Database Organization for PLMN = PLMN_3GPP

UE_Location – 3GPP (CellId) – Other (Geopriv)	AccessType = WiMAX	AccessType = WiFi
Locn_1 Cell_Id = Cell_1	NSP-ID= NSP_1: -NAP_ID = NAP_1 -NAP_ID = NAP_2 NSP-ID = NSP_2 -NAP_ID = NAP_2 -NAP_ID = NAP_3	SSID = WiFi1, BSSID = BS1 SSID = WiFi2, BSSID = BS2
Locn_2 Cell_Id = Cell_2	NSP-ID = NSP_2 – NAP_ID = NAP_3	N/A
Locn_3 Cell_Id = Cell_3	N/A	SSID = WiFi1, BSSID = BS3 SSID = WiFi4, BSSID = BS4
…..	…….	…….
Locn_n Cell_Id = Cell_n	NSP-ID = NSP_1 NAP_ID = NAP_2	SSID = WiFi6, BSSID = BS5

For WiMAX network the database provides information about WiMAX NSP and NAP that provide coverage in respective 3GPP cells. Thus for example in 3GPP Cell_1, WiMAX Service provider NSP_1 provides service to WiMAX radio access providers NAP_1 and NAP-2. Similarly WiMAX Service Provider NSP_2 provides service to Network access providers NAP-2 and NAP_3 as well. Similarly in 3GPP Cell_2 WiMAX Network Service Provider NSP_2 provides service to network Access Provider NAP_3. Further it can be seen that no WiMAX coverage is available in 3GPP cell Cell_3.
