22、 certain subscribers within a regionally restricted area or areas. The motivation for this concept is to create means for network operators to build new service and tariff packages, which take into account subscriber groups and their needs. The localised service area is both an optional network feat
23、ure and an optional UE feature. Usage and implementation of the different SoLSA service features may vary according to operators service packages. This feature is not intended to replace the existing method of cell selection, cell indication and handover. “Support of Localised service area (SoLSA)”

Cells being part of different localised service are
28、as may have overlapping coverage areas. The cells constituting a localised service area may not necessarily provide continuous coverage. Figure 1: Localised Service Area Subscribed to LSA: Set of LSAs, which the user has subscribed to. Valid LSA: A LSA ,whichthe user has subscribed to and his UE can
29、 receive service. Current LSA: The LSA where a UE is receiving service. LSA Priority: Priority of subscribers LSAs. When the user has several valid LSAs, the current LSA shall be selected by prioritising LSAs in case of overlapping LSAs. Figure 2: Localised Service Areas LSA only access: LSA user is

35、ation of the subscriber. 4.1 Defining subscriber information for localised service area A subscriber can have up to 20 LSAs per PLMN. It shall be possible to assign localised service areas to subscribers. Subscriber may have service, which contains several LSAs potentially belonging to different PLM
36、Ns. There shall be means to allocate LSA priority to each subscriber independently by operator. Localised service areas for subscriber(s) may overlap, i.e. one cell may be part of several LSAs belonging to that subscriber. As an example, within a hierarchical cell structure, cells in different layer
37、s can constitute different localised service areas. A localised service area could be defined so that it is possible to establish flexible sized areas, which are applicable to - a very small localised service area (“home area“ covering one or several cells dedicated e.g. to a residential subscriber
38、or a company); or - a large area covering a part of the city (one or several location areas); or - a combination of these. Thus it is possible to use the various radio network configurations. The definition of location areas and the definition of localised service areas may be independent of each ot
39、her. 4.2 Service Features Following service features are building blocks for SoLSA based services. It is up to the operator to decide which service features are required for a specific service. - Localised service area indication. - Localised service area support in idle mode (camping). - Localised
40、service area support in active mode (handover). - LSA only access. - Exclusive access. - Preferential access. 4.2.1 Localised service area indication It shall be possible to assign a subscriber defined identifier by the operator to each LSA (alphanumeric text up to 10 characters), which can be provi
41、ded to the user in idle and active mode. As a UE manufacturer option the user may assign an icon or another form of indication to each LSA. It shall be possible to indicate a change of localised service area during idle and active mode. The indication is a network option (activated/deactivated by th
42、e network). ETSI ETSI TS 142 043 V14.0.0 (2017-04)93GPP TS 42.043 version 14.0.0 Release 144.2.2 Localised service area support in idle mode (camping) The PLMN shall determine, which cells, belonging to the LSA, are to be favoured by the UE when camping. When camping on a cell in idle mode, the subs
43、cribers mobile station shall use the information provided by the PLMN in selecting cells belonging to his localised service area. The mobile station shall have the ability to reselect a cell in a different LSA with higher priority. This favouring shall not degrade the overall service quality. There
44、should be no extra delay in cell selection procedure. 4.2.3 Localised service area support in active mode (handover) The PLMN shall determine, which cells, belonging to the LSA, are to be favoured during active mode. The cells belonging to users LSAs shall be favoured at call setup and when handover
45、s are carried out. This favouring shall not degrade the overall service quality. 4.2.4 Exclusive access For a cell belonging to one or more service areas and where only one or more specific subscribers shall have allowed access, other subscribers mobile stations shall be prevented from using the cel
46、l to obtain any service, other than TS12 (Emergency Calls). NOTE: This does not prevent other subscribers mobile stations from camping on the cell to perform Location Updating. Handovers into cells belonging to localised service areas where only specific subscribers shall have allowed access, shall
47、be possible to be prevented for other subscribers, if required by a SoLSA application. 4.2.5 LSA only access With access allowed only within one or more localised service areas, it shall be possible to prevent receiving and/or originating basic services from non-LSA cells. SMS and Supplementary serv
48、ice operations are allowed in all areas. It shall be possible to prevent handovers to cells not belonging to allowed localised service areas, if required by a SoLSA application. 4.2.6 Preferential access It shall be possible to allocate resources at call setup and during the active mode to LSA users
49、, if required by a SoLSA application. NOTE: An example of a requirement: the last traffic channel is not allocated to non-LSA user or in case of congestion an ongoing call of a non-LSA user is released and replaced with a call of a LSA user. 5 Impact on other services 5.1 General SoLSA is not limited to specific services and there are no modifications necessary for existing services. In particular there shall be no impact to Emergency Call (TS12). LSA should be able to support all tele, bearer and supplementary services .There is no interaction to supplement
