The Location Service (LS) defined in the present
37、document leverages the Zonal Presence service described in SCF 084.07.01 i.1 and in SCF 152.07.01 i.2. The Location Service is accessible through the API defined in the Open Mobile Alliance (OMA) specification “RESTful Network API for Zonal Presence“ 5. ETSI ETSI GS MEC 013 V1.1.1 (2017-07) 8 In add
38、ition to referencing the OMA API 5, the present document contains application instructions on how to apply the OMA API 5 in the MEC environment, and application instructions on how the Anonymous Customer Reference (ACR) defined in 6 can be applied to fulfil the ETSI MEC requirement Location-04 on ad

40、o provide the location related information to the Mobile edge platform or authorized applications. With location related information, the Mobile edge platform or applications perform the active device location tracking, location-based service recommendation, etc. see ETSI GS MEC 002 2. The Location
41、Service is registered and discovered over the Mp1 reference point defined in ETSI GS MEC 003 3. The Location Service supports the location retrieval mechanism, i.e. the location is reported only once for each location information request. The Location Service supports the location subscribe mechanis
42、m, i.e. the location is able to be reported multiple times for each location request, periodically or based on specific events, such as location change. The Location Service supports the anonymous location report, i.e. without the related UE ID information, e.g. for the statistics collection. The Lo
43、cation Service supports the following location information: the location information of specific UEs currently served by the radio node(s) associated with the Mobile edge host; the location information of all UEs currently served by the radio node(s) associated with the Mobile edge host; the locatio
44、n information of a certain category of UEs currently served by the radio node(s) associated with the Mobile edge host; a list of UEs in a particular location area; the specific UEs which move in or out of a particular location area; information about the location of all radio nodes currently associa
45、ted with the Mobile edge host. The Location Service supports both geolocation, such as a geographical coordinates, and logical location, such as a Cell ID. 5.2 Relation with OMA API for Zonal Presence The Zonal Presence service utilizes the concept of “zone“, defined in OMA API 5. According to the d
46、efinition therein, a zone lends itself to be used to group all the radio nodes that are associated to a Mobile edge host, or a subset of them, according to the desired deployment. The OMA Zonal Presence API provides means to an application to retrieve information about a zone, the access points asso
47、ciated to the zones and the users that are connected to the access points. In addition, the OMA Zonal Presence API, allows authorized application to subscribe to a notification mechanism, reporting about user activities within a zone. In the present document, clauses 6 and 7 define how the OMA Zonal
48、 Presence API is used to provide the Mobile edge Location Service. ETSI ETSI GS MEC 013 V1.1.1 (2017-07) 9 5.3 Sequence diagrams 5.3.1 Introduction Clauses 5.3.2 to 5.3.7 describe how the Service Consumers interact with the Location Service over LS API to obtain location information of a UE, a group
49、 of UEs or the radio nodes currently associated with the Mobile edge host. The sequence diagrams that are relevant for the Location Service are presented. The Service Consumers communicate with the Location Service over the LS API. Both the Mobile edge application and Mobile edge platform can be Service Consumers. Location information can be provided by both Mobile edge platform and Mobile edge application. The Location Service API supports both queries and sub
