It provides communication possibilities for mobile users. For communications between mobile and fixed users, interworling with a fixed network is necessary. A GMR-2 PSMN is a PSMN which is in accordance with the GMR-2 Specifications. A GMR-2 PSMN may provide service in the frequency band in the GMR-2 Specifications. As a rule, a GMR-2 PSMN is not limited by the borders of a country. Depending on national regulations there may be more than one GMR-2 PSMN per country. A relationship exists between each subscriber and his home GMR-2 PSMN (HPSMN). If communications are handled over another GMR-2 PSMN, this PSMN is referred to as the visited GMR-2 PSMN (VPSMN). If communications are handled over a GSM PLMN, this PLMN is referred to as the visited GSM PLMN (VPLMN). The HPSMN may be either a GMR-2 PSMN or a GSM PLMN. GMR-2 PSMN Area (GPA) The GMR-2 PSMN Area (GPA) is the geographical area in which a GMR-2 PSMN provides communication services according to the GMR-2 specifications to mobile users. Several Gateways may share a PSMN ID or may have unique PSMNs. In the GPA, the mobile user can set up calls to a user of a terminating network. The terminating network may be a fixed network, the same or different GMR-2 PSMN, a GSM PLMN or other types of PLMN. Terminating network users can also set up calls to the GMR-2 PSMN. A GPA may span a large geographic region, such as several countries. A GPA may span a complete country or may have a region of coverage within a country. Multiple GPAs may cover mutually exclusive regions of service coverage or they may overlap. GMR-2 Service Area A GMR-2 Service Area is defined as a geographic region of coverage of permanent signalling resources. The signalling resources are useable by a MES from a signal strength perspective. An MES can camp on a Gateway when it is in the Service Area of the Gateway. Roaming - General requirements A MES with a valid IMSI may roam and access service in the area authorized by the entitlement of the subscription. If a communication has been established, the MES will in principle not suffer an interruption within the GMR-2 PSMN area (provided the entitlement of the subscription allows it). Exceptions are possible if no network resources or radio coverage are available locally. However, if the MES leaves the GMR-2 PSMN area, an established communication may terminate. If the user then wants to continue, another network providing service has to be selected and a new communication has to be established (see clause 5). 4.1 Roaming Roaming is a service whereby an MES of a given PSMN is able to obtain service from any other PSMN. The availability of Roaming is subject to inter-PSMN agreements. 2 Copyright Telecommunications Industry Association Provided by IHS under license with EIALicensee=IHS Employees/1111111001, User=Wing, Bernie Not for Resale, 03/29/2007 23:50:13 MDTNo reproduction or networking permitted without license from IHS -,-,- TINEIA IS-781.02.01 1 5 Provisions for providing continuity of service 5.1 Location registration GMR-2 PSMNs shall provide a location registration function with the main purpose of providing continuity of service to mobile stations over the entire subscriber area. The location registration function shall be such as to allow: - Fixed subscribers to call a MES by only using the directory number of the MES irrespective of where the MES is located in the GMR-2 system area at the time of the call. - Mobile Earth Stations to access the system irrespective of the location of the MES. Mobile Earth Stations to identify when a change in location area has talten place in order to initiate automatic location updating procedures. - The system architecture enabling implementation of the above requirements is defined in Specification GMR-2 03.002 3. The technical realisation of location registration is defined in Specification GMR-2 03.012 4. Specification GMR 03.012 4 also gives the conditions when a location updating has to talte place. 5.2 Network selection 5.2.1 General The MES shall support both manual and automatic network selection mechanisms (modes). The MES shall select the last mode used, as the default mode, at every switch-on. NOTE: By defaulting to the last mode used, e.g. manual network selection, the undesired automatic selection of an adjacent PSMN instead of the desired HPSMN in border areas, can be avoided at switch-on. The user shall be given the opportunity to change mode at any time. Except as defined below, the MMI shall be at the discretion of the MES manufacturer. The MES shall contain display functions in accordance with GSM 02.07 2, by which Available PLMNs and the Selected PLMN can be indicated. 5.2.2 Procedures 5.2.2.1 Gen era I In the following procedures the MES selects and attempts registration on PSMNs. In this specification, the term 'PSMN Selection' defines an MES based procedure, whereby candidate PSMNs are chosen, one at a time, for attempted registration. If registration on a PSMN is successful, the MES shall indicate this PSMN (the 'registered PSMN') and be capable of malting and receiving calls on it. The identity of the registered PSMN shall be stored on the SIM. However, if registration is unsuccessful, the MES shall ensure that there is no registered PSMN stored in the SIM. If a registration is unsuccessful because the IMSI is unknown in the home network, or the MES is illegal, then the MES shall not allow any further registration attempts on any network, until the MES is next powered-up or a SIM is inserted.

To avoid unnecessary registration attempts, lists of forbidden PSMNs and LAS are maintained in the Mobile Earth Station, see 5.2.2.4 and GMR-2 03.022 5. Registration attempts shall not be made by MESS without a SIM inserted. An MES/ME which has not successfully registered shall nevertheless be able to malte emergency call attempts on an available PSMN, without the need for the user to select a PSMN. An available PSMN is determined by radio characteristics (GMR-2 03.022 5/05.008 7 refers). 5.2.2.2 At switch-on or recovery from lack of coverage If the MES is within coverage (at switch-on) or returns to coverage of the PSMN on which it is already registered (as indicated by the registered PSMN stored in the SIM), the MES shall perform a location update to a new location area if necessary. If there is no registered PSMN stored in the SIM, or if this PSMN is unavailable, or the attempted registration fails, the MES shall follow one of the following two procedures depending on its network selection mode, automatic or manual: A) Automatic network selection mode The MES shall select and attempt registration on other PSMNs, if available and allowable and the location area is not in the list of “forbidden LSs fo
