`
`Definitions and abbreviations
`
`In addition to the abbreviations given in the remainder ofthis clause others are listed in GSM 01 .04.
`
`2.1
`
`Location register
`
`To enable communication to 21 mo bile station the network must know where this mo bile station is located. This
`
`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 Location 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.
`
`2.1.3
`
`Serving GPRS Support Node (SGSN) $(GPRS)$
`
`The location register function in the SGSN stores subscription information and location information for each subscriber
`registered in the SGSN.
`
`The SGSN is needed only in a PLMN which supports GPRS.
`
`2.1.4
`
`Gateway GPRS Support Node (GGSN) $(GPRS)$
`
`The location register function in the GGSN stores subscription information and routeing information (needed to tunnel
`packet data traffic destined for a GPRS MS to the SGSN where the MS is registered) for each subscriber for which the
`GGSN has at least one PDP context active.
`
`The GGSN is needed only in a PLMN which supports GPRS.
`
`2.2
`
`Authentication Centre (AuC)
`
`The Authentication Centre (AuC) is an entity which stores data for each 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, MSC and SGSN which need to authenticate a mobile station.
`
`ZTE Corporation and ZTE (USA) Inc.
`
`Exhibit 1005.02-00008
`
`

`
`GSM 03.02 version 6.1.0 Release 1997
`
`TS 100 522 V6.1.0 (1998-07)
`
`The procedures used for authentication and ciphering are described n1ore fully in GSM 03.20.
`
`2.3
`
`Equipment Identity Register (EIR)
`
`The Equipment identity Register (ElR) in the GSM system is the logical entity which is responsible for storing in the
`network the international Mobile Equipment Identities (IMEIS), used iI1 the GSM system.
`
`The equipment is classified as "white listed", "grey listed", "black listed" or it may be unknown as specified in
`GSM 02.l6 and GSM 09.02.
`
`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 coverage of a given geographical area a number of base stations are normally required; i.e. each
`MSC would thus have to interface several base stations. in addition several MSCs may be required to cover a country.
`
`2.5
`
`Border Gateway (BG) $(GPRS)$
`
`The Border Gateway (BG) is a gateway between a PLMN supporting GPRS and an external inter—PLMN backbone
`network used to interconnect with other PLM.\ls also supporting GPRS. The role ofthe BC} is to provide the appropriate
`level of security to protect the PLMN and its subscribers.
`
`The BG is only needed in PLMNs supporting GPRS.
`
`2.6
`
`Public Land Mobile Network (PLMN)
`
`A Public Land Mobile Network (PLMN) is established 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 PLlV[N may be regarded as an extension of a network (e.g. ISDN); it is a collection of MSCs areas within a
`common numbering 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 PLlV|Ns may be regarded as independent telecommunications entities even though different PLMNs
`may be interconnected through the ISDN/PSTN 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.
`
`2.7
`
`Cell
`
`The cell is an area of radio coverage identified by a Base station identification as defined in GSM 03.03.
`
`2.8
`
`Base 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 the boundary between location areas.
`
`2.9
`
`Location Area (LA)
`
`The Location Area (LA) is defined as an area in which a mobile station may move freely without updating the VLR. A
`location area may include one or several cells.

`
`2.10
`
`Routing Area (RA) $(GPRS)$
`
`The Routing Area (RA) is defined as an area in which a mobile station, in certain operation modes, may move freely
`without updating the SGSN. A routing area may include one or several cells. A RA is always contained within a location
`area.
`
`2.11
`
`MSC area
`
`The MSC area is the part of the network covered by 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.
`
`2.12
`
`GPRS Support Nodes (GSN) $(GPRS)$
`
`The GPRS support nodes, Gateway GSN (GGSN) and Serving GSN (SGSN) constitutes the interface between the radio
`system and the fixed networks for packet switched services. The GSN performs all necessary functions in order to
`handle the packet transmission to and from the mobile stations.
`
`2.13
`
`VLR area
`
`The VLR area is the part of the network controlled by a VLR. A VLR area may consist of one or several MSC areas.
`
`2.14
`
`SGSN area $(GPRS)$
`
`The SGSN area is the part of the network served by an SGSN. An SGSN area may consist of one or several roL1ting
`areas. An SGSN area may also consist ofone or several BSC areas. There need not be a one to one relationship between
`SGSN area and MSCKVLR area.

`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 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 ofa PLMN.
`
`The definition ofa mobile subscriber's regional subscription area is stored within the HLR per National Destination
`Code(s) (NDC) of a PLMN and is transferred to the VLRS and/or SGSNs of that PLMN. The VLR and/or SGSN
`evaluates this information to extract the restricted or accessible MSC and/or SGNS areas and location areas to which the
`mobile subscriber is allowed to roam. The VLR ancL«'or SGNS informs the HLR if an entire MSC and/or SGNS area is
`restricted.
`
`Zones for Regional Subscription and their handling are defined in GSM 03.03, GSM 03.08 and GSM 09.02.

`
`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 subscriber's knowledge of the actual location of the mobile station within the area. A service area
`may consist of several PLMNs. One service area may consist of one country, be a part 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 located within that service area.
`
`2.17
`
`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

`
`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 broadcast 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.

`
`The 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. ln any case, exchanges of data occur between these
`entities.
`
`3.1
`
`The Home Location 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 ofmobile subscribers, on the capacity of the equipment and on the organisation
`of the network. The following kinds of information are stored there:
`
`-
`
`-
`
`the subscription information;
`
`some location information enabling the charging and routing of calls towards the MSC where the MS is
`registered(e. g. the MS Roaming Number, the VLR Number, the MSC Number, the Local MS Identity).
`
`and, if GPRS is supported, also S(GPRS)$:
`
`-
`
`location information enabling the charging and routing of messages in the SGS.\I where the MS is currently
`registered (e.g. the SGSN Number).
`
`Different types of identity are attached to each mobile subscription and are stored in the HLR. If GPRS is not supported
`the following identities are stored:
`
`-
`
`-
`
`the International Mobile Station Identity (IMSI);
`
`one or more Mobile Station International ISDN number(s) (MSISDN);
`
`while, ifGPRS is supported, the following identities are stored $(GPRS)$:
`
`-
`
`—
`
`-
`
`the International Mobile Station Identity (IMSI);
`
`one or more Mobile Station International ISDN number(s) (MSISDN);
`
`zero or more Packet Data Protocol (PDP) address(es).
`
`There is always at least one identity, apart lrom the lMSl, attached to each mobile subscription and stored in the HLR.
`
`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 such as:
`
`-
`
`-
`
`-
`
`teleservices and bearer services subscription information;
`
`service restrictions (e.g. roaming limitation)_;- a list of all the group lDs a service subscriber is entitled to use to
`establish voice group or broadcast calls;
`
`supplementary services; the HLR contains the parameters attached to these services;

`

`
`GSM 03.02 version 6.1.0 Release 1997
`
`TS 100 522 V6.1.0 (1998-07)
`
`and, if GPRS is supported, also S[GPRS)$:
`
`-
`
`information about if a GGSN is allowed to dynamically allocate PDP addresses for a subscriber.
`
`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 GSM 03.08.
`
`3.2
`
`The Visitor Location Register (VLR)
`
`A mobile station roaming in an MSC area is controlled by the Visitor Location Register in charge of this area. When a
`Mobile Station (MS) enters a new location area it starts a registration 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 registere
