1 IEEE MEDIA INDEPENDENT HANDOVER DCN: Title: SPARQL Query/Response based on TGu examples Date Submitted: November,15th, 2006 Presented at IEEE session #17 in Dallas, Texas. Authors or Source(s): Kenichi Taniuchi, Yoshihiro Ohba, Subir Das Abstract: This document shows how Information Service examples that are cited in TGu presentation can be supported by using SPARQL and XML/RDF Schema

3 TGu Example #1: What WLANs supoort my subscriptions ? STA: provides list of subscriptions 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

4 Query Response (Example #1) operator essid1 operator essid2 ………

5 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 Query Response (Example #2) true

7 TGu Example #3: What interworking services are supported on this WLAN ? STA: provides ESSID(s) 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

8 Query Response (Example #3) operator mihbasic:service-type1 1 ………

9 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 Query Response (Example #4) true

11 TGu Example #5: I’m traveling to Melbourne, what hotspots are located there ? STA: provides location (latitude, longitude), search radius 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. FILTER ((xsd:unsignedLong(?latitude) < 4dcc9fc8 ) && (xsd:unsignedLong(?latitude) > 4dcb9fc8 ) ). ?geo_location_info mihbasic:longitude ?longitude. FILTER ((xsd:unsignedLong(?longitude) < f65ed7031 ) && (xsd:unsignedLong(?longitude) > f65ec7031 ) ). } LIMIT 5 SPQRQL Query

12 Query Response (Example #5) operator essid1 operator essid2 ………
