Omre\u017eje CN sestavljajo naslednje komponente<\/p>\n<p><strong>Preklopni center za mobilne storitve (MSC)<\/strong>: predstavlja vmesnik med radijskim sistemom in fiksnim omre\u017ejem. Izvaja vse potrebne funkcije za upravljanje storitev s preklapljanjem vezij v mobilne postaje in iz njih (3GPP, 2015, str. 26). MSC je obi\u010dajno sestavljen iz dveh sistemov: stre\u017enika MSC, ki je odgovoren za signalizacijo, in medijskega prehoda (MGW), ki upravlja uporabni\u0161ki promet.<\/p>\n<p><strong>Doma\u010di naro\u010dni\u0161ki stre\u017enik (HSS)<\/strong> je glavna zbirka podatkov za dolo\u010denega uporabnika. Je entiteta, ki vsebuje informacije, povezane z naro\u010dnino, za podporo omre\u017enim entitetam, ki dejansko obdelujejo klice\/seje (3GPP, 2015, str. 22). HSS hrani: informacije o identifikaciji, o\u0161tevil\u010denju in naslavljanju uporabnika, varnostne informacije uporabnika, informacije o lokaciji uporabnika in informacije o profilu uporabnika. Funkcijo HSS opravljata dve omre\u017eni komponenti: register doma\u010de lokacije (HLR) in center za avtentikacijo (AuC).<\/p>\n<p><strong>Register doma\u010de lokacije (HLR)<\/strong> je osrednja zbirka podatkov, ki vsebuje podatke o vsakem naro\u010dniku mobilnega telefona, ki je poobla\u0161\u010den za uporabo osrednjega omre\u017eja GSM. Vsak uporabnik je lahko povezan le z enim HLR.<\/p>\n<p><strong>Center za preverjanje pristnosti (AuC)<\/strong> je povezan z dolo\u010denim HLR in hrani identifikacijski klju\u010d za vsakega naro\u010dnika, registriranega pri povezanem HLR. Klju\u010d se uporablja za generiranje varnostnih podatkov, ki se nato uporabljajo za medsebojno avtentikacijo med naro\u010dnikom in omre\u017ejem, za\u0161\u010dito celovitosti in zaupnosti komunikacij (3GPP, 2015, str. 23).<\/p>\n<p><strong>Register lokacij obiskovalcev (VLR)<\/strong> je zbirka podatkov o naro\u010dnikih, ki so se gibali na obmo\u010dju pristojnosti dr\u017eave \u010dlanice, ki ji slu\u017ei. Ko mobilna postaja (MS) vstopi na novo lokacijsko obmo\u010dje, za\u010dne postopek registracije. MSC, pristojen za to obmo\u010dje, opazi to registracijo in v register lokacij obiskovalcev prenese identiteto lokacijskega obmo\u010dja, na katerem se nahaja mobilna postaja (MS). \u010ce ta MS \u0161e ni registrirana v VLR, VLR in HLR izmenjata informacije, da omogo\u010dita pravilno obravnavo klicev CS, ki vklju\u010dujejo MS. V praksi ve\u010dina prodajalcev zaradi u\u010dinkovitosti VLR integrira neposredno v V-MSC (3GPP, 2015, str. 25).<\/p>\n<p><strong>Vrata za kratka sporo\u010dila (SMSC)<\/strong> deluje kot vmesnik med storitvenim centrom za kratka sporo\u010dila in mobilnim omre\u017ejem ter omogo\u010da, da se kratka sporo\u010dila iz storitvenega centra dostavijo mobilnim postajam (3GPP, 2015, str. 26).<\/p>\n<p><strong>To\u010dka za prenos signala (STP)<\/strong> je odgovoren za prenos sporo\u010dil SS7 med drugimi vozli\u0161\u010di SS7 in deluje podobno kot usmerjevalnik v omre\u017eju IP (Dryburgh, Hewet, 2005).<\/p>","protected":false},"excerpt":{"rendered":"<p>SS7 SMS Klicna lokacija GSM Osrednje omre\u017eje GSM (CN) (ali omre\u017eni stikalni podsistem NSS) je sestavni del sistema GSM, ki izvaja preklapljanje klicev in upravljanje mobilnosti za mobilne telefone.
