【正文】 TDD。+=urn%3Aurn7%。高通文檔對(duì)SIM卡要求的描述如下： The UICC card needs to have an ISIM application along with the proper credentials for IMS registration. The credentials include: From the USIM Mobile Subscriber Integrated Services Digital Network Number (MSISDN) – Generally the phone number of the device From the ISIM IMS Private Identity (IMPI) IMS Public Identity (IMPU) Domain – Domain of the home network Security Key – Subscriber key for security authentication OP – Operator algorithm configuration value AuthScheme parameters – Algorithms for security authentication3. 網(wǎng)絡(luò) 要注冊到支持VoLTE的LTE網(wǎng)絡(luò)，并且數(shù)據(jù)網(wǎng)絡(luò)開關(guān)要打開，Default APN要設(shè)置好，Default APN 和 IMS APN的IP地址類型要設(shè)置好（如：IPV4V6）。VoLTE Log分析與主要SIP消息 高通在IMS產(chǎn)品介紹會(huì)上明確說明將VoLTE代碼封裝在Modem里，故VoLTE的Log主要是在Modem里；在Main Log 和 Radio Log里的信息量較少或壓根沒有輸出；Net Log里是SIP消息相關(guān)的，主要是看SIP消息的流程、配置有沒有問題。 省公司HSS簽約數(shù)據(jù)要求如表81所示。+=urn:gsma:imei:865407010000000。+=urn:gsma:imei:865407010000000Route: sip::5060。transport=udpStatus: 200 OK說明：[MS NW] 手機(jī)語音呼叫用戶0123456789[NW MS] 網(wǎng)絡(luò)回復(fù)100 Trying，開始尋呼[NW MS] 網(wǎng)絡(luò)回復(fù)180 Ringing，找到被叫，響鈴振鈴[MS NW] 手機(jī)用PRACK回復(fù)100rel，通知網(wǎng)絡(luò)已收到振鈴消息[NW MS] 網(wǎng)絡(luò)回復(fù)200 OK (PRACK)[NW MS] 網(wǎng)絡(luò)回復(fù)200 OK (INVITE)，被叫應(yīng)答[MS NW] 主叫回復(fù)ACK，呼叫建立……………………. ……………………. 通話中 ……………………. …………………….[MS NW] 主叫發(fā)BYE掛機(jī)[NW MS] 網(wǎng)絡(luò)回復(fù)200 OK，掛斷電話空口消息如下：DLRRC CONNECTION RECONFIGURATIONULRRC CONNECTION RECONFIGURATION COMPLETEULESM: ACTIVATE DEDICATED EPS BEARER CONTEXT ACCEPT//專用承載建立DLRRC CONNECTION RECONFIGURATIONULRRC CONNECTION RECONFIGURATION COMPLETEULESM: DEACTIVATE EPS BEARER CONTEXT ACCEPT//恢復(fù)默認(rèn)承載具體的SIP消息：INVITE sip:0123456789。branch=z9hG4bK3624637363MaxForwards: 70From: 18406630020 sip:001010123456789。user=phone。tag=1111111111CallID: 561128295_185090136CSeq: 561128295 INVITEAllow: INVITE, ACK, CANCEL, BYE, PRACK, UPDATERecordRoute: sip::5060。tag=561128308i: 561128295_185090136CSeq: 561128297 BYEv: SIP/:5060。branch=z9hG4bKf3b6a856a57d467e9437f54d214995ea21dbba51MaxForwards: 69CallID: c64488da3d6644409c0b6324e3cd911cCSeq: 9001 INVITETo: sip:001010123456789From: sip:0123456789。transport=udp,SIP/:60115。audio。transport=udp,SIP/:60115。branch=z9hG4bK2663585505From: sip:001010123456789。2. 空中接口消息 《VoLTE終端測試規(guī)范——（報(bào)批稿）.pdf》 本標(biāo)準(zhǔn)規(guī)定了中國移動(dòng)VoLTE終端通信功能和性能測試方法以及相關(guān)測試用例，包括IMS基本過程、補(bǔ)充業(yè)務(wù)、短消息能力、移動(dòng)性以及性能測試，供中國移動(dòng)內(nèi)部和廠商共同使用；適用于中國移動(dòng)VoLTE終端，是中國移動(dòng)通信集團(tuán)公司及省公司內(nèi)部進(jìn)行的VoLTE終端功能和性能測試時(shí)的技術(shù)依據(jù)。video。tag=1111111111UserAgent: AnritsuVirtualUA/4596ContentLength: 0Privacy: nonePAssertedIdentity: sip:0123456789RecordRoute: sip:。branch=z9hG4bKf3b6a856a57d467e9437f54d214995ea21dbba51CallID: c64488da3d6644409c0b6324e3cd911cCSeq: 9001 INVITETo: sip:001010123456789。branch=z9hG4bKf3b6a856a57d467e9437f54d214995ea21dbba51CallID: c64488da3d6644409c0b6324e3cd911cCSeq: 9001 INVITETo: sip:001010123456789From: sip:0123456789。user=phone3. 被叫流程SIP消息：Request:INVITE sip:001010123456789:5060Status:100 TryingStatus:SIP/ 180 RingingStatus:SIP/ 200 OKRequest: BYE sip:001010123456789:5060Status: SIP/ 200 OK說明：[NW MS] 網(wǎng)絡(luò)尋呼sip:001010123456789[MS NW] 手機(jī)回復(fù)100 Trying[MS NW] 手機(jī)回復(fù)180 Ringing，振鈴[MS NW] 手機(jī)回復(fù)200 OK，應(yīng)答，被叫建立……………………. ……………………. 通話中 ……………………. …………………….[NW MS] 網(wǎng)絡(luò)發(fā)BYE掛機(jī)[MS NW] 手機(jī)回復(fù)200 OK，掛斷電話空口消息如下：DLRRC CONNECTION RECONFIGURATIONULRRC CONNECTION RECONFIGURATION COMPLETEULESM: ACTIVATE DEDICATED EPS BEARER CONTEXT ACCEPT//專用承載建立DLRRC CONNECTION RECONFIGURATIONULRRC CONNECTION RECONFIGURATION COMPLETEULESM: DEACTIVATE EPS BEARER CONTEXT ACCEPT//恢復(fù)默認(rèn)承載具體的SIP消息：INVITE sip:001010123456789:5060 SIP/Via: SIP/:60124。transport=udp SIP/t: sip:0123456789。branch=z9hG4bK3624637363From: 18406630020 sip:001010123456789。user=phonePRACK sip:0123456789:55379。+=urn%3Aurn7%。phonecontext=. 。+=urn%3Aurn7%。 這里只列出IMS注冊、主叫、被叫、eSRVCC、PS上收發(fā)SMS，退注冊的SIP消息和空中接口消息，其他的SIP消息請(qǐng)閱讀《41融合通信接口規(guī)范（終端平臺(tái)接口分冊）（技術(shù)參考版）.pdf》、《41融合通信接口規(guī)范（終端平臺(tái)接口分冊）（技術(shù)參考版）》(兩個(gè)文檔內(nèi)容一樣，word格式易于搜索)，其他的空中接口消息請(qǐng)閱讀《VoLTE終端測試規(guī)范——（報(bào)批稿）.pdf》。 所有碼號(hào)由網(wǎng)絡(luò)配置，通過終端配置服務(wù)下發(fā)到終端。檢查點(diǎn)：1.
