6、 in a Next Generation Network (NGN) Environment 1 1 Introduction This Technical Report (TR) describes the support of Location Based Commercial Services in the IP environment of a Next Generation Network (NGN). Location Based Commercial Services acquire geographical location information about one or
7、more targets and provide services, based on that location information, to the user invoking the service. Examples of Location Based Commercial Services include Directory Assistance, Information Services (e.g., weather), Navigation Services, Friends and Family Finder Services, and Vehicle Tracking Se
8、rvices. The Location Based Commercial Services may or may not support call center agents. This TR: Provides an example set of Location Based Commercial Services, Describes the NGN/IP architecture that supports such services, Provides end to end information flows based on existing ATIS, Open Mobile A
9、lliance (OMA), and IETF Geographical Location/Privacy (GEOPRIV) standards, and Concludes that such services can be supported by existing standards. The end-to-end information flows and the analysis focus on authorization (i.e., for the Location Based Commercial Service to obtain and use the location
10、 information) and privacy (i.e., the ability of the user to control the release and use of private location information.) 2 Normative References 1 ATIS-1000009 ATIS-1000009.2006, IP Network-to-Network Interface (NNI) Standard for VoIP12 ATIS-1000018 ATIS-1000018, NGN Architecture February 200713 RFC

22、troller TR Technical Report VoIP Voice over IP 4 Description of Location Based Commercial Services Location Based Commercial Services are Commercial Services that make use of a target location of interest to the user invoking the service. The location may or may not be the current (or even future) p
23、hysical location of the user. When the information identifying the location of interest (the “target Location Information,” or “TLI”) reflects the current physical location of the user, it is obtained by a Location Server and is delivered to the Location Based Commercial Service. In this case, the T
24、LI may be generated from one or more technologies, such as Assisted Global Positioning System (A-GPS), cell-ID, Enhanced Observed Time Difference (EOTD), and may be relatively fixed (as TLI for a wireline subscriber) or may vary over time (as TLI associated with a WIFI or Bluetooth.) When the TLI do
25、es not reflect the current physical location of the user, it may be obtained by a Location Server or by the Location Based Commercial Service itself. Location Based Commercial Services include (but are not limited to) the following categories: Operator Services (e.g., Directory Assistance DA) Inform
26、ation Services (operator assisted and automated) Navigation Services Finder Services ATIS-1000043 4 Vehicle Tracking Services Social Networking Services. 4.1 Location Based Operator Services Location Based Operator Services are the subset of Operator Services that make use of TLI. Operator Services
27、include the services defined in the NGN Operator Services Standard ATIS-1000036, Intercept, Busy Line Verification, Coin Services, and Handling of Restricted Lines. Most Operator Services do not make use of the target location. Examples of Operator Services that may process TLI include DA and Enhanc
28、ed Directory Assistance (EDA). 4.2 Location Based Information Services Location Based Information Services are the subset of Information Services that make use of TLI. Information Services in an NGN consist of a broad range of services that provide content to a user in response to a user request. Th
29、e content may be provided in any format, such as graphic, text, video, and voice. The content may be delivered in a number of ways (e.g., voice may be delivered as a .wav file or may be streamed via a voice connection.) Example Information Services that could benefit from TLI include weather and oth
30、er proximity-based searches (e.g., searching for a nearby gas station). 4.3 Navigation Services Navigation are services that provide maps and directions to users based on the TLI. By their nature, navigation services are location-based. 4.4 Finder Services Finder Services are services that provide t
31、he location of a target (e.g., child, pet) to the user. By their nature, finder services are location-based. 4.5 Vehicle Tracking Services Finder Services are services that provide the location of the vehicle being tracked to an authorized tracker for that vehicle. By their nature, navigation servic
32、es are location-based. 4.6 Social Networking Services Social Networking Services are services that rely on the correlation of the locations of multiple users. These services help users answer questions such as: Which users who have registered as friends of mine (or as people with interests similar t
33、o mine) are nearby? Which customers who have registered with my store are currently inside the store? ATIS-1000043 5 By their nature, social networking services are location-based. 5 NGN/IP Architecture In this TR, the network architecture that provides the context for Location Based Services is tak
34、en from the ATIS Technical Report on NGN Architecture ATIS-1000018 with the assumption that the Location Based Commercial Service is provided from a Voice over IP (VoIP) network. With its focus on the Location Based Commercial Services AS, this standard does not address the Access SBC, Charging Func
35、tion, or Home Subscriber Server (HSS). Therefore, the effective functional architecture for is as shown in Figure 1.

39、ession Control Function The LBCS may have multiple of any of the AS, MS or database (db) components, i.e., any of these functions may be distributed across multiple physical elements. The LBCS may be hosted by or resident within a VoIP Provider network different from the one serving the caller. Alth
40、ough call origination and completion may occur from/to VoIP or PSTN endpoints, location information is not assumed to be delivered into the PSTN. Location information may be delivered from one VoIP service provider network to another. As for the details of the service logic for providing particular
41、Location Based Commercial Services, discussion of the dbs is out of scope of this Technical Report. Note that the service logic may allow for one or more methods of obtaining permission to use the location information. Some examples of methods are: 1. The service may be subscribed to by the target p
42、arty (e.g., a vehicle tracking service agrees to allow the service to obtain the location of a vehicle whenever the service is legitimately invoked.) 2. The service may obtain permission from the target party on a per-incident basis (e.g., by invoking a navigation service, the invoking party grants
43、permission for the service to obtain the target location.) TLI may be requested (pulled) as needed from the Location Server or the service may involve the periodic transmission (push) of current TLI from the Location Server. Typically, the information will be pulled from or pushed to an Application
44、Server (AS) or a Media Server (MS). The service description may allow or disallow the AS or MS that obtains TLI from the Location server to store the TLI. If storing TLI is allowed, the service may or may not allow the TLI to be pulled or pushed to another network entity or to an end user. Some serv
45、ices (e.g., vehicle tracking) require the ability to share the TLI with a third party. Note that the target location may not be associated with either end of a call (and that there may not be any call associated with the service.) 5.1 Terminology The following terms are used in this document. Civic
46、Location The civic location is comprised of the street address corresponding to a physical location. Geodetic Location The geodetic location is comprised of geospatial coordinates corresponding to a physical location. Location Server - The location server is the functional entity that handles locati
47、on requests and responds with location (civic or geodetic) information associated with a target. For a mobile network using Open Mobile Alliance (OMA) Location Service in SIP/IP core network (LOCSIP), the Location Server corresponds to the Location Server and Location Resource List Server (L-RLS). A
48、TIS-1000043 7 Location Quality of Service (QOS) Information The QOS information includes the required, desired, or achieved level of quality of Location Information in terms of minimum horizontal and vertical accuracy, maximum response time, and maximum age. Target The person or entity whose locatio
49、n is communicated to one or more Recipients. Note that the Target may or may not be the calling or called party of a call. Recipient The entity that receives the location of one or more targets. Target Location Information The geodetic or civic location information that identifies the physical location of the target. This information may also include other information related to the location, such as usage rules. User The person or
