This
21、information is stored in a function named location register. 2.1.1 Home Location Register (HLR) The Home Location Register (HLR)is the location register to which a mobile subscriber is assigned for record purposes such as subscriber information. 2.1.2 Visitor Location Register (VLR) The Visitor Loca
22、tion Register (VLR) is the location register, other than the HLR, used by an MSC to retrieve information for, e.g. handling of calls to or from a roaming mobile station currently located in its area. 2.2 Authentication Centre (AuC) The Authentication Centre (AuC) is an entity which stores data for e
23、ach mobile subscriber to allow the International Mobile Subscriber Identity (IMSI) to be authenticated and to allow communication over the radio path between the mobile station and the network to be ciphered. The AuC transmits the data needed for authentication and ciphering via the HLR to the VLR a
24、nd MSC which need to authenticate a mobile station. The procedures used for authentication and ciphering are described more fully in TS GSM 03.20. 2.3 Equipment Identity Register (ER) The Equipment Identity Register (EIR) in the GSM system is the logical entity which is responsible for storing in th
25、e network the International Mobile Equipment Identities (IMEls), used in the GSM system. The equipment is classified as “white listed“, “grey listed“, “black listed“ or it may be unknown as specified in GSM 02.16 and GSM 09.02.

26、arch 1996 2.4 Mobile-services Switching Centre (MSC) The Mobile-services Switching Centre (MSC) constitutes the interface between the radio system and the fixed networks. The MSC performs all necessary functions in order to handle the calls to and from the mobile stations. In order to obtain radio c
27、overage of a given geographical area a number of base stations are normally required; .e. each MSC would thus have to interface several base stations. In addition several MSCs may be required to cover a country. 2.5 Public Land Mobile Network (PLMN) A Public Land Mobile Network (PLMN) is established
28、 and operated by an administration or Recognized Private Operating Agency (RPOA) for the specific purpose of providing land mobile telecommunications service services to the public. A PLMN may be regarded as an extension of a network (e.g. ISDN); it is a collection of MSCs areas within a common numb
29、ering plan (e.g. same National Destination Code) and a common routing plan. The MSCs are the functional interfaces between the fixed networks and a PLMN for call Set-up. Functionally the PLMNs may be regarded as independent telecommunications entities even though different PLMNs may be interconnecte
30、d through the ISDNIPSTN and PDNs for forwarding of calls or network information. A similar type of interconnection may exist for the interaction between the MSCs of one PLMN. 2.6 cell The cell is an area of radio coverage identified by a Base station identification as defined in TS GSM 03.03. 2.7 Ba
31、se Station Controller (BSC) area The Base Station Controller (BSC) area is an area of radio coverage consisting of one or more cells controlled by one BSC. The boundaries of a BSC area and a location area are independent; a location area may span the boundary between BSC area and a BSC area may span
32、 the boundary between location areas. 2.8 Location Area (LA) The Location Area (LA) is defined as an area in which a mobile station may move freely without updating the location register. A location area may include one or several cells. 2.9 MSC area The MSC area is the pari of the network covered b
33、y an MSC. An MSC area may consist of one or several location areas. An MSC area may also consist of one or several BSC areas. ETSI GSM*03.02 %b II 3400855 0096733 698 = Page 11 GSM 03.02 version 5.0.0: March 1996 2.10 VLR area The VLR area is the part of the network controlled by a VLR. A VLR area m
34、ay consist of one or several MSC areas. 2.1 1 Zones for Regional Subscription A PLMN operator may define a number of regional subscription areas, each of which is a subset of the service area for an unrestricted mobile subscriber. A regional subscription area may be contained within the service area
35、 of a single PLMN, or may lie within the service areas of two or more PLMNs. Each regional subscription area consists of one or more zones; each zone is contained within the service area of a PLMN. The definition of a mobile subscribers regional subscription area is stored within the HLR per Nationa
36、l Destination Code) (NDC) of a PLMN and is transferred to the VLRs of that PLMN. The VLR evaluates this information to extract the restricted or accessible MSC areas and location areas to which the mobile subscriber is allowed to roam. The VLR informs the HLR if an entire MSC area is restricted. Zon
37、es for Regional Subscription and their handling are defined in GSM 03.03, GSM 03.08 and GSM 09.02. 2.12 Service area The service area is defined as an area in which a mobile subscriber can be reached by another (mobile or fixed) subscriber without the subscribers knowledge of the actual location of
38、the mobile station within the area. A service area may consist of several PLMNs. One service area may consist of one country, be a pari of a country or include several countries. The location registration system associated with each service area must thus contain a list of all mobile stations locate
39、d within that service area. 2.13 Group call area The group call area is a predefined area composed of one or a number of cells to which a particular Voice Group Call Service (VGCS) or Voice Broadcast Service (VBS) call is distributed. The composition of a group call area is predefined in the network
40、. The group call area may include cells of more than one MSC area and cells of more than one PLMN. 2.14 Group Call Register (GCR) The Group Call Register (GCR) is a register holding information about VGCS or VBS calls, the voice group or broadcast call attributes, respectively. Voice group or broadc
41、ast call attributes are defined for a specific voice group or broadcast call reference and include the data required to configure the conference bridge for a VGCS or VBS call and other call related attributes.

42、he entities of the mobile system To provide the mobile service as it is defined, it is necessary to introduce some specific functions. These functional entities can be implemented in different equipments or gathered. in any case, exchanges of data occur between these entities. 3.1 The Home Location
43、Register (HLR) This functional entity is a data base in charge of the management of mobile subscribers. A PLMN may contain one or several HLRs: it depends on the number of mobile subscribers, on the capacity of the equipment and on the organisation of the network. Two kinds of information are stored
44、 there: - the subscription information; - some location information enabling the charging and routing of calls towards the MSC where the MS is located (e.g. the MS Roaming Number, the VLR address, the MSC address, the Local MS Identity). Two types of number are attached to each mobile subscription a
45、nd are stored in the HLR: - the International Mobile Station Identity (IMSI); - one or more Mobile Station International ISDN number) (MSISDN). The IMSI or the MSISDN may be used as a key to access the information in the database for a mobile subscription. The data base contains other information su
46、ch as: - teleservices and bearer services subscription information; - service restrictions (e.9. roaming limitation); - a list of all the group IDS a service subscriber is entitled to use to establish voice group or broadcast calls: - supplementary services; the HLR contains the parameters attached
47、to these services. NOTE: Supplementary services parameters need not all be stored in the HLR. However, it seems safer to store all subscription parameters in the HLR even when some are stored in a subscriber card. The organisation of the subscriber data is outlined in TS GSM 03.08. - ETSI: GSM*03.02

When a Mobile Station (MS) enters a new location area it starts a registration
49、procedure. The MSC in charge of that area notices this registration and transfers to the Visitor Location Register the identity of the location area where the MS is situated. If this MS is no yet registered, the VLR and the HLR exchange information to allow the proper handling of calls involving the MS. A VLR may be in charge of one or several MSC areas. The VLR contains also the information needed to handle the calls Set-up or received by the MSs registered in its data base (for some supplementary services the VLR may have to obtain additional information from th
