Introduction The objective of this feasibility study is to outline the technical requirements, scope of work required, and perform a gap analysis to determine whether existing 3GPP specifications can s
23、upport LCS requirements for 3GPP WLAN interworking. If it is determined that providing for this service is feasible, then this feasibility study will continue forward to encompass future work. ETSI ETSI TR 122 935 V13.0.0 (2016-01)53GPP TR 22.935 version 13.0.0 Release 131 Scope The 3GPP has develop
24、ed and continues to develop Location Services (LCS) requirements and standards for GSM and UMTS. To further the advancement of LCS within the 3GPP, LCS requirements and standards may be extended for 3GPP WLAN interworking to support the same location-based services that have been deployed today for
25、GSM and UMTS. LCS with 3GPP WLAN Interworking system is considered to enlarge the area of location services. The purpose of the feasibility study is to study a generic interworking functionality for LCS between 3GPP system and WLAN systems (e.g. IEEE 802.11 family, HIPERLAN/2, ). Specifically, the f
26、easibility study aims to: - Study the LCS requirements for 3GPP WLAN Interworking scenarios. - Study the different possible LCS architectures for interworking. Also, the feasibility study will: - Assess the service requirements for support of LCS over I-WLAN - Define the MMI aspects, i.e., the minim
27、um set of functions to support LCS when the choice of access system by the user and/or terminal for when both access systems is available. - Assess the charging requirements and architecture impacts. In particular, consider whether or not WLAN charging for LCS should be integrated with the architect
28、ure for UMTS charging for LCS. - Assess the security requirements, given the prerequisite that a) the security level of the UMTS platform itself is not impacted, b) the security level provided to users in the WLAN mode is comparable to the one of UMTS. 2 References The following documents contain pr

Change of Area means that the network is required to report the location or the occurrence
38、of the event of the requested subscriber in triggered fashion immediately after the network (MSC/SGSN) processes the mobility event for the new location of the subscriber. Usually new location is noticed after the Location Update, Handover, RAU, Registration or RANAP Location Report, e.g. when the S
39、AI changes. Codeword: access code, which is used by a Requestor or LCS Client in order to gain acceptance of a location request for a Target UE. The codeword is part of the privacy information that may be registered by a Target UE user. Current Location: after a location attempt has successfully del
40、ivered a location estimate and its associated time stamp, the location estimate and time stamp are referred to as the current location at that point in time. Deferred location request: a location request where the location response (responses) is (are) required after specific event has occurred. Eve
41、nt may or may not occur immediately. In addition event may occur many times. Immediate location request: a location request where a single location response only is required immediately. Initial Location: in the context of an originating emergency call the location estimate and the associated time s
42、tamp at the commencement of the call set-up is referred to as initial location. ETSI ETSI TR 122 935 V13.0.0 (2016-01)73GPP TR 22.935 version 13.0.0 Release 13Last Known Location: The current location estimate and its associated time stamp for Target UE stored in the LCS Server is referred to as the
43、 last known location and until replaced by a later location estimate and a new time stamp is referred to as the last known location. LCS Client: a software and/or hardware entity that interacts with a LCS Server for the purpose of obtaining location information for one or more Mobile Stations. LCS C
44、lients subscribe to LCS in order to obtain location information. LCS Clients may or may not interact with human users. The LCS Client is responsible for formatting and presenting data and managing the user interface (dialogue). The LCS Client is identified by a unique international identification, e
45、.g. E.164. NOTE: The LCS Client may reside inside or outside the PLMN. LCS Client Access barring list: an optional list of MSISDNs per LCS Client where the LCS Client is not allowed to locate any MSISDN therein. LCS Client Subscription Profile: a collection of subscription attributes of LCS related
46、parameters that have been agreed for a contractual period of time between the LCS client and the service provider. LCS Feature: the capability of a PLMN to support LCS Client/server interactions for locating Target UEs. LCS Server: a software and/or hardware entity offering LCS capabilities. The LCS
47、 Server accepts requests, services requests, and sends back responses to the received requests. The LCS server consists of LCS components which are distributed to one or more PLMN and/or service provider. Service Identifier: A service provided by an LCS Client is identified by a Service Identifier.
48、One LCS client may have one or more services. The combination of the LCS client Identifier and the Service Identifier constitute a unique identification of a service. Location Estimate: the geographic location of a UE and/or a valid Mobile Equipment (ME), expressed in latitude and longitude data. Th
49、e Location Estimate shall be represented in a well-defined universal format. Translation from this universal format to another geographic location system may be supported, although the details are considered outside the scope of the primitive services. PLMN Access barring list: an optional list of MSISDN per PLMN where any LCS Client is not allowed to locate any MSISDN therein except for certain exceptional cases. Privacy Class: list of LCS Clients defined within a privacy exception class to which permission may be granted t
