htc 10手機訊號設定問題

因為小弟拿的是htc10所以來這邊發問

請問各位大大知不知道
輸入*#*#4636#*#*後進入手機測試
進入以下畫面

htc 10手機訊號設定問題

htc 10手機訊號設定問題
然後該選擇哪個選項
才可以將行動網路固定在4G
又可以讓人家打的進來

我所在的環境訊號很不穩定
明明收得到4G
但一直跳成3G或H
如果我把選項調成 LTE only
訊號的確只會收到4G
但是別人根本打不進來
只會快速的嘟嘟嘟然後掛斷

所以想請問一下專業的大大可以幫個忙 謝謝


補充:那請問平常選哪一個會比較好?

這問題就是4G訊號太弱不穩定才會一直跳。
目前鎖4G only就是無法打電話,
除非雙方都有開通VoLTE。
4G是IP網路,3G是電路交換網路,所以不能互通,
要靠CSFB(Circuit Switched Fallback)切換系統,
因此打電話會切到2/3G,結束會再跳回4G。


我也常這樣鎖,之前中華網路太差一直跳,
一方面想一直留在4G,一方面上班不想接電話,
檔各銀行與壽險行銷電話很有用,
有人打來會有來電通知,重要再切回自動打回去。

Network Mode用這個APP可以快速進入網路工模
要在4G狀態 別人能打進來 目前只能用VOLTE

缺點是雙方手機都要開通VOLTE

不然只能用LINE之類的通訊軟體了
本身使用亞太VOLTE卡
撥打跟接電話,與一般3G通話一樣
並沒有什麼一定要VOLTE才能互通
謝謝luck1177大大解說的這麼詳細

我來下載試看看 這樣比較方便一點~
抱歉 小弟是台哥大的 台哥大的限制是要都開通才能

其他業者我就不清楚了

LTE的技術規範就是這樣說的

VoLTE tutorial-Voice Over LTE basics and types
This VoLTE tutorial covers VoLTE (Voice Over LTE) basics, types of VoLTE which include VoLTE using IMS(VOIP) and VoLTE using CSFB(SRVCC).

LTE is all IP based network and mainly designed for internet/data applications. Hence to support voice over LTE there are two options. The first is using VOIP(voice vover IP) with the help of IMS(IP Multimedia system) and the the second one is using legacy 2G/3G Circuit Switched Fall Back(CSFB) with the concept called SRVCC. We will see below how these works.

VoLTE using IMS(VOIP)

As shown in the figure above in LTE called EUTRAN comprised of more than one eNodeB. eNodeB in LTE has functionalities of RNC and NodeB of 3G. MME,S-GW,HSS and P-GW will form EPC(Evolved Packet Core). eNodeBs and EPC form EPS(Evolved Packet System). LTE supports voice call using VOIP using IMS. If it is VOIP to VOIP call, it will remain within LTE network and supported using VOIP protocols. But if it is VOIP to CS call for GSM/WCDMA network, IMS with the help of application servers and legacy MSC transfers the PS call to legacy networks (2G-GERAN/3G-UTRAN). If it is VOIP to PSTN call, IMS directs through PSTN interface to respective exchanges.

VoLTE using 2G/3G CSFB(using SRVCC)

When UE moves from LTE network to say legacy networks(GSM/WCDMA), based on measurement report submitted by UE handover is performed and tranfer of Voice over IP call to legacy voice call is performed . This to happens UE should support SRVCC. SRVCC stands for Single Radio Voice Call Continuity. It means UE will be connected with sigle radio at a time and hence one single RAT(either LTE or GSM or WCDMA). Hence battery life becomes longer here with SRVCC capable UE.

4G只有在VoLTE的技術下才能通話,不然通話都必須轉至3G或2G。
