3 21-05-0820-00-0000 TGu Example #1: What WLANs supoort my subscriptions ? STA: provides list of subscriptions 80-2.21-IS: provides list of {SSPN, SSID, ESSID} where SSPN’s includes roaming partners Assumptions: SSPN:TYPE_IE_SERVICE_PROVIDER_IDENTIFIER SSID:TYPE_IE_POA_ADDRESS ESSID:TYPE_IE_ACCESS_NETWORK_IDENTIFIER PREFIX mihbasic: SELECT ?sspn ?ssid ?essid WHERE { ?network mihbasic:network-type "19". ?network mihbasic:roaming-partner ?roaming_partner. ?roaming_partner mihbasic:operator-name "my subscriptions". ?network mihbasic:access-network-identifier ?essid. ?network mihbasic:service-provider-identifier ?sspn. ?network mihbasic:poa ?poa. ?poa mihbasic:poa-address ?poa_address. ?poa_address mihbasic:address ?ssid } SPQRQL Query

5 21-05-0820-00-0000 TGu Example #2: Is emergency service supported on this WLAN ? STA: provides ESSID(s) Assumptions: SPARQL can create yes/no query using ASK PREFIX mihbasic: ASK { ?network mihbasic:network-type "19". ?network mihbasic:access-network-identifier "this essid". ?network mihbasic:poa ?poa. ?poa mihbasic:poa-capabilities ?poa_capabilities. ?poa_capabilities mihbasic:poa-emergency-service “1”. } SPQRQL Query

6 21-05-0820-00-0000 Query Response (Example #2) true

7 21-05-0820-00-0000 TGu Example #3: What interworking services are supported on this WLAN ? STA: provides ESSID(s) 802.21-IS: provides list of {SSPN, SSID, ESSID, interworking services} Assumptions: Interworking services: TYPE_IE_SERVICE_TYPE Example: Emergency Service, Location Service, etc. TYPE_IE_SERVICE_TYPE has already been defined in Basic Schema PREFIX mihbasic: SELECT ?sspn ?ssid ?service_name ?service_value WHERE { ?network mihbasic:network-type "19". ?network mihbasic:access-network-identifier "this essid". ?network mihbasic:service-provider-identifier ?sspn. ?network mihbasic:poa ?poa. ?poa mihbasic:poa-address ?poa_address. ?poa_address mihbasic:address ?ssid. ?network mihbasic:service-type ?service_type ?service_type ?service_name ?service_value} SPQRQL Query

9 21-05-0820-00-0000 TGu Example #4: Is VoIP services provided on this WLAN ? STA: provides ESSID(s) Assumption: VoIP bit is in TYPE_IE_SERVICE_TYPE SPARQL can create yes/no query using ASK PREFIX mihbasic: ASK { ?network mihbasic:network-type "19". ?network mihbasic:access-network-identifier "this essid". ?network mihbasic:service-type ?service_type. ?service_type mihbasic:voip-service “1”. } SPQRQL Query

10 21-05-0820-00-0000 Query Response (Example #4) true

11 21-05-0820-00-0000 TGu Example #5: I’m traveling to Melbourne, what hotspots are located there ? STA: provides location (latitude, longitude), search radius 802.21-IS: provides list of {SSPN, SSID, ESSID} which support VoIP This could potentially generate a lengthly query response Assumptions: If radius is small the list would be small, SPARQL can adjust the distance If use LIMIT option of SPARQL, it can adjust the number of the contents PREFIX mihbasic: PREFIX xsd: SELECT ?sspn ?ssid ?essid WHERE {?network mihbasic:network-type "19". ?network mihbasic:access-network-identifier ?essid. ?network mihbasic:service-provider-identifier ?sspn. ?network mihbasoc:poa ?poa. ?poa mihbasic:poa-address ?poa_address. ?poa_address mihbasic:address ?ssid. ?poa mihbasic:poa-location ?poa_location. ?poa_location mihbasic:geospatial-location-information ?geo_location_info. ?geo_location_info mihbasic:latitude ?latitude.
