5、OTE ETSI has constituted stable and consistent documents which give specifications for the implementation of the European Cellular Telecommunications System. Historically, these documents have been identified as “GSM recommendations“. * Some of these recommendations may subsequently become Interim E
6、uropean Telecommunications Standards (I-ETSs) or European Telecommunications Standards (ETSs), whilst some continue with the status of ETSI-GSM Technical Specifications. These ETSI-GSM Technical Specifications are for editorial reasons still referred to as GSM recommendations in some current GSM doc
7、uments. The numbering and version control system is the same for ETSI-GSM Technical Specifications as for “GSM recommendations“. 3404583 0074037 945 GSM 11.31 - version 3.2.1 - Page 2 o. SCOPE The scope of this report is to give guidelines concernlng the specification of the Home Location Register (
8、HLR). in the case of discrepancy between this report and the approved core GSM recommendations the later shall prevail. Each functlon is specified as either mandatory or optional. The different functions provided by the HLR are ide iified with an indication of the rei; 3nt recommendations where t. i
9、efinitlve specifications can be und. The purpose of this re-rt is to give an overview or the HLR functions needed to imciement the GSM system, in order to help both the Administrations/OperatOrs in the procurement of their equipments and the manufacturers tendering the HLR. A list of the contents wh
10、ich may be found in a national specification for such equipment is given as an appendix to this report. GSM, but are left to the discretion of the operators. Note that some items in this list are not specified by 1. I“ The HLR, as described in this and all other GSM recommendatlons, is not a physica
11、l entity and need not be implemented as such, it is, rather, a set of functions which are required to manage the mobile nature of subscribers belonging to the HLR. The HLR provides a known, fixed location to provide the variable routing information, subscription state, supplementary service activati
12、on state and other information about an inherently mobile subscriber. Functionally the HLR will always point to a VLR and the VLR will point to the MS location area, though in actual implementation it would be possible to implement some VLR functions in a physical entity looking more like a HLR e.g.
13、 storing TMSI, location area identification and other VLR functions relating to home subscribers. HLR functions may be incorporated into a single physical entity or distributed or combined with other PLMN entities such as a MSC. 2. DEFINITIONS The term Home Location Register (HLR) is defined in Reco
14、mmendation GSM 01.04 and a more full description can be found in Recommendations GSM 03.02 and 09.02. 3404583 0074018 881 H GSM 11.31 - version 3.2.1 - Page 3 3. ARCHITECTURE The network architecture is defined in Recommendatlon GSM 03.02 where it is shown how the HLR is related to other functional
15、entities of the PLMN. order to meet various national needs and allow flexibility for future development of PLMNs. In particular the HLR is shown both as a stand-alone entity with interfaces in the PLMN, incorporated into a MSC. Several configurations are presented in and as Irrespective of national
16、solutions the requirements specified below as mandatory are required in order to allow full connectivity of PLMNs nationally and internationally. 4- INTERFACE The HLR must support signalling to and from MSCs, and VLRs (both. of the home and other PLMNs). Depending on the capabilities of exchanges in
17、 public switched networks, the HLR may support signalling to these networks in order to accommodate the interrogation procedure of Secommendatlon GSM 03.04. Normally, these interfaces will require Signalling System no 7 MAP. The signalling used to provide information transfer between a HLR and OMC i
18、s a national matter. However, international standards are emerging which will facilitate the transfer of such information between HLRs and different OMC implementations, using standard protocols. These standards will be embodied in the Telecommunication Management Network (TMN) concept - this is des
19、cribed in Recommendation GSM 12.00. Also, Recommendations GSM 12.01 and 12.14 define information transfer principles with other O-or data The HLR must store subscriber data for home MSs. Recommendation GSM 03.08 gives the full description. The HLR should also be able to store data corresponding to o

21、ures to be used after outage of the HLR itself or after outage of a VLR. 7.
