NB-IoT: inoshanda sei? Chikamu 3: SCEF - hwindo rimwe chete rekuwana kune opareta masevhisi

Muchinyorwa "NB-IoT: inoshanda sei? Chikamu 2", tichitaura nezve magadzirirwo epacket core yeNB-IoT network, takataura nezve kutaridzika kweiyo itsva SCEF node. Tinotsanangura muchikamu chechitatu kuti chii uye nei ichidiwa?

Paunenge uchigadzira sevhisi yeM2M, vanogadzira maapplication vanotarisana nemibvunzo inotevera:

• nzira yekuziva michina;
• ndeipi yekuongorora uye yekusimbisa algorithm yekushandisa;
• iyo yekufambisa protocol yekusarudza yekudyidzana nemidziyo;
• nzira yekuendesa data nenzira yakavimbika kumidziyo;
• kuronga uye kumisikidza mitemo yekuchinjana data navo;
• maitiro ekutarisa uye kuwana ruzivo nezve mamiriro avo online;
• maitiro ekuendesa data panguva imwe chete kuboka remidziyo yako;
• maitiro ekutumira data panguva imwe chete kubva kune imwe mudziyo kune akati wandei vatengi;
• nzira yekuwana kuwana kwakabatana kune mamwe opareta masevhisi ekugadzirisa mudziyo wako.

Kuti uzvigadzirise, zvinodikanwa kugadzira proprietary tekinoroji "inorema" mhinduro, izvo zvinotungamira kune yakawedzera mutengo wevashandi uye nguva-yeku-musika masevhisi. Apa ndipo panouya iyo itsva SCEF node kuzonunura.

Sezvinotsanangurwa ne3GPP, SCEF (sevhisi kugona kuratidzwa basa) chinhu chitsva chose cheiyo 3GPP architecture ine basa rekufumura zvakachengeteka masevhisi uye kugona kunopihwa ne3GPP network interfaces kuburikidza nemaAPI.

Nemashoko akareruka, SCEF murevereri pakati penetiweki nesevha yekushandisa (AS), hwindo rimwe chete rekuwana kune opareta masevhisi ekutonga yako M2M mudziyo muNB-IoT network kuburikidza neinonzwisisika, yakamisikidzwa API interface.

SCEF inovanza kuomarara kwetiweki yemushandisi, ichibvumira vanogadzira maapplication kuti vatore kure yakaoma, mudziyo-chaiyo nzira dzekudyidzana nemidziyo.

Nekushandura network protocol kuita yakajairika API yevagadziri vekushandisa, iyo SCEF API inofambisa kugadzirwa kwemasevhisi matsva uye kuderedza nguva-kumusika. Iyo node nyowani inosanganisirawo mabasa ekuzivisa / kutendesa nharembozha, kutsanangura mirairo yekutsinhana kwedata pakati pechishandiso neAS, kubvisa kudiwa kwevanovandudza maapplication kuti vaite mabasa aya parutivi rwavo, vachichinjisa mabasa aya kumapfudzi emushandisi.

SCEF inovhara iyo inopindirana inodiwa kuti isimbiswe uye mvumo yemasevha ekushandisa, kuchengetedza UE kufamba, kuendesa data uye kukonzeresa mudziyo, kuwana mamwe masevhisi uye opareta network kugona.

Kutarisa AS kune imwechete T8 interface, API (HTTP/JSON) yakamisikidzwa ne3GPP. Zvose zvinopindirana, kunze kweT8, zvinoshanda zvichienderana neDIAMETER protocol (Fig. 1).

T6a - interface pakati peSCEF neMME. Inoshandiswa kuMobility / Session manejimendi maitiro, kutapurirana kwete-IP data, kupihwa kwekutarisa zviitiko uye kugamuchira mishumo pazviri.

S6t - interface pakati peSCEF neHSS. Inodiwa kuti munyoreri abvumidzwe, mvumo yemasevha ekushandisa, kuwana musanganiswa wekunze ID uye IMSI/MSISDN, kupa zviitiko zvekutarisa uye kugamuchira mishumo pazviri.

S6m/T4 - inopindirana kubva kuSCEF kuenda kuHSS uye SMS-C (3GPP inotsanangura iyo MTC-IWF node, iyo inoshandiswa kugadzira mudziyo uye kutumira maSMS muNB-IoT network. SCEF, saka kuitira kurerutsa dunhu, isu hatizozvifunga zvakasiyana). Inoshandiswa kuwana ruzivo rwenzira yekutumira SMS uye kushamwaridzana neSMS centre.

T8 - API interface yeSCEF yekudyidzana nemaseva ekushandisa. Yese mirairo yekudzora uye traffic inofambiswa kuburikidza neiyi interface.

*muchokwadi kune mamwe mainterface; chete iwo akanyanya kukosha akanyorwa pano. Rondedzero yakazara inopiwa mu 3GPP 23.682 (4.3.2 Rondedzero yeReference Points).

Pazasi pane akakosha mabasa uye masevhisi eSCEF:

• kubatanidza iyo SIM kadhi identifier (IMSI) kune yekunze ID;
• kutapurirana kweasiri-IP traffic (Isiri-IP Data Delivery, NIDD);
• mashandiro eboka uchishandisa ekunze boka ID;
• tsigiro yekufambiswa kwedata mode nekusimbisa;
• kubhafa kweMO (Mobile Originated) uye MT (Mobile Terminated) data;
• kutendeseka uye mvumo yemidziyo uye maseva ekushandisa;
• kushandiswa panguva imwe chete yedata kubva kune imwe UE nemaAS akati wandei;
• tsigiro yeakakosha eEU mamiriro ekutarisa mabasa (MONTE - Monitoring Zviitiko);
• device triggering;
• inopa isiri-IP data roaming.

Nheyo yekutanga yekudyidzana pakati peAS neSCEF yakavakirwa pane inonzi chirongwa. kuzvinyoresa. Kana zvichidikanwa kuti uwane mukana kune chero sevhisi yeSCEF yeUE chaiyo, sevha yekushandisa inoda kugadzira kunyoreswa nekutumira murairo kune chaiyo API yebasa rakakumbirwa uye kugamuchira yakasarudzika identifier mukupindura. Mushure mezvo zvese zvimwe zviito uye kutaurirana neEU mukati meiyo sevhisi sevhisi zvichaitika uchishandisa iyi identifier.

External ID: Universal mudziyo identifier

Imwe yeshanduko dzakanyanya kukosha muchirongwa chekudyidzana pakati peAS nemidziyo paunenge uchishanda kuburikidza neSCEF kutaridzika kwechiziviso chepasirese. Ikozvino, pachinzvimbo chenhamba dzerunhare (MSISDN) kana IP kero, sezvazvaive mune yekare 2G/3G/LTE network, chinongedzo chemudziyo weseva yekushandisa chinova "ID yekunze". Inotsanangurwa neyakajairwa mufomati inozivikanwa kune vanogadzira application " @ "

Vagadziri havachadi kushandisa algorithms yekusimbisa mudziyo; network inotora zvachose basa iri. ID yekunze yakasungirirwa kuIMSI, uye mugadziri anogona kuve nechokwadi chekuti kana awana chaiyo yekunze ID, inodyidzana neimwe SIM kadhi. Paunenge uchishandisa SIM chip, iwe unowana yakasarudzika mamiriro apo iyo yekunze ID inozivisa yakasarudzika mudziyo!

Zvakare, akati wandei ekunze maID anogona kubatanidzwa kune imwe IMSI - inotonyanya kunakidza mamiriro anomuka apo iyo yekunze ID inozivisa yakasarudzika application ine basa rakati pane chimwe chinhu.

Mucherechedzo weboka unoonekwawo - ID yeboka rekunze, iyo inosanganisira seti yemunhu ekunze maID. Ikozvino, nechikumbiro chimwe kuSCEF, AS inogona kutanga mashandiro eboka - kutumira data kana kutonga mirairo kumidziyo yakawanda yakabatana muboka rimwe chete rine musoro.

Nekuda kwekuti kune vanogadzira AS shanduko kuenda kune itsva mudziyo identifier haigone kuitika ipapo, SCEF yakasiya mukana weAS kutaurirana neEU kuburikidza nenhamba yakajairwa - MSISDN.

Kufambiswa kweiyo isiri-IP traffic (Isiri-IP Data Delivery, NIDD)

MuNB-IoT, sechikamu chekugadzirisa kwemaitiro ekufambisa mashoma e data, kuwedzera kune yatovepo mhando dzePDN, dzakadai se IPv4, IPv6 uye IPv4v6, imwe mhando yakaonekwa - isiri-IP. Muchiitiko ichi, mudziyo (UE) hauna kupihwa IP kero uye data inotamiswa pasina kushandisa IP protocol. Traffic yekubatanidza kwakadaro inogona kufambiswa nenzira mbiri: yekare - MME -> SGW -> PGW uyezve kuburikidza nePtP tunnel kuenda AS (Fig. 2) kana kushandisa SCEF (Fig. 3).

Iyo yekirasi nzira haipe chero yakakosha mabhenefiti pamusoro peIP traffic, kunze kwekudzikisa saizi yemapaketi anofambiswa nekuda kwekushaikwa kweIP misoro. Iko kushandiswa kweSCEF kunovhura akati wandei mikana mitsva uye inorerutsa zvakanyanya maitiro ekudyidzana nemidziyo.

Kana uchitumira data kuburikidza neSCEF, maviri akakosha mabhenefiti anoonekwa pamusoro pekirasi IP traffic:


Kuendeswa kweMT traffic kune mudziyo kuburikidza nekunze ID

Kuti utumire meseji kune yekare IP mudziyo, iyo AS inofanirwa kuziva yayo IP kero. Pano pane dambudziko rinomuka: sezvo chigadziri chinowanzogamuchira "grey" IP kero pakunyoresa, inotaurirana nevhavha yekushandisa, iyo iri paInternet, kuburikidza node yeNAT, apo kero yegrey inoshandurirwa muchena. Iko kusanganiswa kwegrey uye chena IP kero inogara kwenguva shoma, zvichienderana neNAT marongero. Paavhareji, yeTCP kana UDP - isingasviki maminetsi mashanu. Ndiko kuti, kana pasina kuchinjana kwemashoko nemudziyo uyu mukati memaminitsi e5, kushamwaridzana kuchaparara uye chigadziro hachichakwanisi kuwanikwa kune kero chena iyo sangano neAS yakatangwa. Pane zvakawanda zvinogadzirisa:

1. Shandisa kurova kwemwoyo. Kana chinongedzo changotangwa, mudziyo unofanirwa kuchinjana mapaketi neAS maminetsi ega ega, zvichidzivirira kuvharwa kweNAT. Asi hapagoni kuva nekutaura kwekushanda kwesimba chero kupi zvako pano.

2. Nguva dzose, kana zvichidiwa, tarisa kuwanikwa kwepakeji yemudziyo pa AS - tumira meseji kune uplink.

3. Gadzira yakavanzika APN (VRF), apo sevha yekushandisa uye zvishandiso zvichange zviri pane imwechete subnet, uye ipa static IP kero kumidziyo. Ichashanda, asi inenge isingagoneki kana isu tichitaura nezve ngarava yezviuru, makumi ezviuru zvemidziyo.

4. Chekupedzisira, sarudzo yakanyatsokodzera: shandisa IPv6, haidi NAT, sezvo IPv6 kero inowanikwa zvakananga kubva kuInternet. Nekudaro, kunyangwe mune iyi kesi, kana mudziyo ukanyoreswa zvakare, uchagamuchira itsva IPv6 kero uye hauchasvikike uchishandisa yapfuura.

Nekudaro, zvinodikanwa kutumira imwe yekutanga pakiti ine chiziviso chemudziyo kune server kuitira kuti utaure iyo itsva IP kero yechishandiso. Wobva wamirira pakiti yekusimbisa kubva kuAS, iyo inokanganisawo kushanda kwesimba.

Idzi nzira dzinoshanda zvakanaka kune 2G / 3G / LTE zvishandiso, apo chigadziro chacho hachina zvidikanwi zvekuzvimiririra uye, semugumisiro, hapana zvipingamupinyi pane airtime uye traffic. Idzi nzira hadzina kukodzera kuNB-IoT nekuda kwekushandisa kwavo simba zvakanyanya.

SCEF inogadzirisa dambudziko iri: sezvo chiziviso chega chega cheAS chiri ID yekunze, iyo AS inongoda kutumira pakiti yedata kuSCEF kune chaiyo ID yekunze, uye SCEF inotarisira zvimwe. Kana mudziyo uri muPSM kana eDRX magetsi ekuchengetedza modhi, data inozovharwa uye kuendeswa kana mudziyo wawanikwa. Kana chishandiso chiripo chetraffic, iyo data ichaendeswa nekukurumidza. Zvimwe chetezvo kune zvikwata zvevatungamiri.

Chero nguva, iyo AS inogona kuyeuka meseji yakavharwa kuEU kana kuitsiva neimwe nyowani.

Iyo buffering michina inogona zvakare kushandiswa kana uchitumira MO data kubva kuUE kuenda kuAS. Kana SCEF ikatadza kuendesa data kuAS nekukasira, semuenzaniso kana basa rekugadzirisa richienderera mberi pamaseva eAS, mapaketi aya anozovharwa uye anovimbiswa kuendeswa nekukurumidza kana AS yavepo.

Sezvakataurwa pamusoro apa, kuwana kune imwe sevhisi uye UE yeAS (uye NIDD ibasa) inodzorwa nemitemo nemitemo kudivi reSCEF, iyo inobvumira mukana wakasiyana wekushandisa panguva imwe chete yedata kubva kune imwe UE nemaAS akati wandei. Avo. kana akati wandei AS akanyoresa kune imwe UE, ipapo mushure mekugamuchira data kubva kuEU, SCEF inotumira kune vese vakanyoresa AS. Izvi zvakanyatsokodzera zviitiko apo mugadziri weboka rezvishandiso zvehunyanzvi anogovera data pakati pevatengi vakati wandei. Semuenzaniso, nekugadzira network yezviteshi zvemamiriro ekunze zvinomhanya paNB-IoT, unogona kutengesa data kubva kwavari kune akawanda masevhisi panguva imwe chete.

Iyo yakavimbiswa meseji nzira

Reliable Data Service inzira yekuvimbiswa kutumirwa kweMO neMT mameseji pasina kushandiswa kwehunyanzvi algorithms padanho reprotocol, senge, semuenzaniso, kubata maoko muTCP. Inoshanda nekusanganisira mureza wakasarudzika muchikamu chesevhisi chemeseji painotsinhana pakati peUE neSCEF. Kunyangwe kana kusaita iyi meshini kana yekufambisa traffic inosarudzwa neAS.

Kana iyo meshini ikamiswa, iyo UE inosanganisira yakakosha mureza muchikamu chepamusoro chepaketi kana ichida kuvimbiswa kuburitswa kweMO traffic. Pakugashira pakiti yakadaro, SCEF inopindura kuEU nemvumo. Kana iyo UE ikasagashira pakiti yekubvuma, packet yakananga kuSCEF inozotumirwa zvakare. Chinhu chimwe chete chinoitika kune MT traffic.

Kutarisisa mudziyo (kutarisa zviitiko - MONTE)

Sezvambotaurwa pamusoro, mashandiro eSCEF, pakati pezvimwe zvinhu, anosanganisira mabasa ekutarisa mamiriro eEU, inonzi. device monitoring. Uye kana zviziviso zvitsva uye nzira dzekufambisa data dziri optimizations (kunyangwe yakakomba) yemaitiro aripo, saka MONTE ibasa idzva zvachose risingawanikwe mu2G/3G/LTE network. MONTE inobvumira AS kuti itarise ma parameter echishandiso senge mamiriro ekubatanidza, kuwanikwa kwekutaurirana, nzvimbo, mamiriro ekutenderera, nezvimwe. Tichazotaura pamusoro peumwe neumwe zvakadzama gare gare.

Kana zvichidikanwa kumisa chero chiitiko chekutarisa chemudziyo kana boka remidziyo, iyo AS inonyoresa kune inoenderana sevhisi nekutumira inoenderana API MONTE kuraira kuSCEF, iyo inosanganisira ma paramita akadai seyekunze Id kana yekunze ID yeboka, AS identifier, yekutarisa. mhando, nhamba yemishumo, iyo AS inoda kugamuchira. Kana iyo AS inobvumirwa kuita chikumbiro, SCEF, zvichienderana nerudzi, ichapa chiitiko kune HSS kana MME (Fig. 4). Kana chiitiko chikaitika, iyo MME kana HSS inoburitsa chirevo kuSCEF, iyo inotumira kune AS.

Kupa zviitiko zvese, kunze kwe "Nhamba yeUE iripo munzvimbo yenzvimbo", inoitika kuburikidza neHSS. Zviitiko zviviri "Shanduko yeIMSI-IMEI Association" uye "Roaming Status" inoteverwa zvakananga paHSS, zvimwe zvichapihwa neHSS paMME.
Zviitiko zvinogona kuva imwe-nguva kana nguva nenguva, uye zvinotemerwa nerudzi rwavo.

Kutumira mushumo pamusoro pechiitiko (kurondedzera) kunoitwa nenode inotarisa chiitiko chacho zvakananga kuSCEF (Fig. 5).

Nhau inokosha: Zviitiko zvekuona zvinogona kuiswa kune ese ari maviri asiri-IP zvishandiso zvakabatana kuburikidza neSCEF uye IP zvishandiso zvinotumira data nenzira yechinyakare kuburikidza neMME-SGW-PGW.

Ngatitarisei zvakanyanya pane chimwe nechimwe chezviitiko zvekutarisa:

Kurasikirwa kwekubatana - inozivisa iyo AS kuti iyo UE haichawanikwi kune chero data traffic kana kusaina. Chiitiko ichi chinoitika kana "mobile accessability timer" yeEU yapera paMME. Muchikumbiro cherudzi urwu rwekutarisa, iyo AS inogona kuratidza kukosha kwayo kwe "Maximum Detection Time" - kana panguva ino iyo UE isingaratidze chero chiitiko, iyo AS ichaziviswa kuti iyo UE haisipo, zvichiratidza chikonzero. Chiitiko ichi chinoitikawo kana iyo UE yakabviswa nechisimba netiweki chero chikonzero.

* Kuita kuti network izive kuti mudziyo uchiri kuwanikwa, nguva nenguva inotanga maitiro ekuvandudza - Yekutevera Nzvimbo Yekuvandudza (TAU). Kuwanda kwemaitiro aya kunoiswa netiweki uchishandisa timer T3412 kana (T3412_extended munyaya yePSM), kukosha kwayo kunopfuudzwa kune mudziyo panguva yeAttach maitiro kana inotevera TAU. Nharembozha inosvika nguva inowanzoita maminetsi akati wandei kureba kupfuura T3412. Kana iyo UE isati yaita TAU isati yapera ye "Mobile accessability timer", network inoiona senge isingachasvikike.

UE kusvika -Inoratidza kana iyo UE inowanikwa kune DL traffic kana SMS. Izvi zvinoitika kana iyo UE yave kuwanikwa yepeji (yeUE mueDRX modhi) kana iyo UE ikapinda ECM-CONNECTED modhi (yeUE muPSM kana eDRX modhi), i.e. inoita TAU kana kutumira uplink packet.

Mharidzo yenzvimbo -Iyi mhando yezviitiko zvekutarisa inobvumira iyo AS kubvunza nzvimbo yeEU. Ingave nzvimbo yazvino (Nzvimbo Yazvino) kana yekupedzisira inozivikanwa nzvimbo (Inotemerwa nesero ID kubva iyo mudziyo wakagadzira TAU kana kutumira traffic nguva yekupedzisira) inogona kukumbirwa, iyo yakakosha kune zvishandiso muPSM kana eDRX magetsi ekuchengetedza maitiro. Ye "Nzvimbo Yazvino", iyo AS inogona kukumbira mhinduro dzinodzokororwa, neMME ichizivisa iyo AS pese painochinja nzvimbo yemuchina.

Shanduko yeIMSI-IMEI Association - Kana chiitiko ichi chaitwa, SCEF inotanga kutarisa shanduko mukusanganiswa kweIMSI (SIM kadhi identifier) ​​uye IMEI (mudziyo wemudziyo). Kana chiitiko chikaitika, inozivisa AS. Inogona kushandiswa kusungira otomatiki ID yekunze kumudziyo panguva yakarongwa yekutsiva basa kana kushanda sechiratidzo chekubiwa kwemudziyo.

Roaming Status - iyi mhando yekutarisisa inoshandiswa neAS kuona kuti iyo UE iri munetwork yepamba here kana kuti munetiweki yemumwe munhu anotenderera. Sarudzo, iyo PLMN (Public Land Mobile Network) yeanoshanda iyo mudziyo wakanyoreswa inogona kutapurirwa.

Kukundikana kwekutaurirana -Iyi mhando yekutarisa inozivisa iyo AS nezve kutadza kutaurirana nemudziyo, zvichibva pane zvikonzero zvekurasikirwa kwekubatanidza (kuburitsa chikonzero kodhi) yakagamuchirwa kubva kune redhiyo yekuwana network (S1-AP protocol). Ichi chiitiko chinogona kubatsira kuona kuti nei kutaurirana kwakundikana - nekuda kwematambudziko padandemutande, semuenzaniso, kana iyo eNodeb yakawandisa (Radio zviwanikwa hazviwanikwe) kana nekuda kwekutadza kwechishandiso pachayo (Radio Connection neUE Yakarasika).

Kuwanikwa mushure meDDN Kukundikana - chiitiko ichi chinozivisa AS kuti mudziyo wave kuwanikwa mushure mekutadza kutaurirana. Inogona kushandiswa kana paine kudikanwa kwekuendesa data kune mudziyo, asi kuedza kwekare hakuna kubudirira nekuti iyo UE haina kupindura kune chiziviso kubva kunetiweki (paging) uye iyo data haina kuendeswa. Kana rudzi urwu rwekutarisa rwakumbirwa kuUE, ipapo pakarepo kana chigadziri chichiita kutaurirana kunouya, kuita TAU kana kutumira data kune uplink, iyo AS ichaziviswa kuti chigadzirwa chave chiripo. Sezvo iyo DDN (downlink data notification) maitiro achishanda pakati peMME neS/P-GW, rudzi urwu rwekutarisa runongowanikwa kumidziyo yeIP chete.

PDN Yekubatanidza Status - inozivisa AS kana chimiro chemudziyo chachinja (PDN yekubatanidza mamiriro) - yekubatanidza (PDN activation) kana kubviswa (PDN kudzima). Izvi zvinogona kushandiswa neAS kutanga kutaurirana neEU, kana zvinopesana, kuti unzwisise kuti kutaurirana hakuchagoneke. Iyi mhando yekutarisa inowanikwa kune IP uye isiri-IP zvishandiso.

Nhamba yeEU iripo munzvimbo yenzvimbo -Iyi mhando yekutarisisa inoshandiswa neAS kuona huwandu hweUE mune imwe nzvimbo yenzvimbo.

Device triggering)

Mune 2G/3G network, nzira yekunyoresa munetiweki yaive nhanho mbiri: yekutanga, mudziyo wakanyoreswa neSGSN (attach process), zvino, kana zvichidikanwa, yakamisa mamiriro ePDP - kubatana negedhi repaketi (GGSN) kutumira data. Mune 3G network, aya maviri maitiro akaitika sequentially, i.e. mudziyo hauna kumirira nguva payaida kuendesa data, asi yakabatidzwa PDP nekukurumidza mushure mekunge maitiro ekubatanidza apera. MuLTE, maitiro maviri aya akasanganiswa kuita imwe, kureva, pakusungirirwa, chishandiso chakabva chakumbira activation yePDN yekubatanidza (inofanana nePDP mu2G/3G) kuburikidza neNodeB kuenda kuMME-SGW-PGW.

NB-IoT inotsanangura nzira yekubatanidza se "batanidza pasina PDN", kureva kuti, iyo UE inonamatira pasina kumisikidza PDN yekubatanidza. Muchiitiko ichi, haisi kuwanikwa kuendesa traffic, uye inogona kungogamuchira kana kutumira SMS. Kuti utumire murairo kumudziyo wakadaro kuti uite PDN uye ubatanidze kune AS, "Device triggering" kushanda kwakagadzirwa.

Paunenge uchigamuchira murairo wekubatanidza UE yakadaro kubva kuAS, SCEF inotanga kutumira yekudzora SMS kune mudziyo kuburikidza neSMS centre. Paunenge uchigamuchira SMS, mudziyo unomutsa PDN uye unobatana neAS kuti ugamuchire mimwe mirairo kana kutumira data.

Panogona kunge paine nguva dzekuti kunyoreswa kwemudziyo wako kunopera paSCEF. Ehe, kunyoreswa kwacho kune hupenyu hwayo, hwakaiswa nemushandisi kana kubvumirana neAS.
