物聯網架構及議題

物聯網面臨的議題

大量的連線終端需求,需有大量IP 位址的配發。

基地台連線數有數量的限制,每一細胞最大1500個終端,未來需升版提供更多的終端容量。

NB IOT窄頻物聯裝置的需求,因此3GPP R12新增Cat 0、 R13

(2016/3/11)新增Cat M0、CatM1規範,可以提供較低頻寬、低成本的物聯裝置。

相較於H2H服務(Human-to-Human),M2M物聯網服務需要考量以下議題:

產品封裝考慮:

目前手機上的SIM卡為可移除式,但由於物聯網裝置通常處於密封狀態以適用於較嚴酷的環境,例如智慧型儀器(水電錶)或戶外感測裝置(攝影機、浮標),因此不可移除式SIM卡的設計對於物聯網裝置有其必要性。

連線成本及速度考慮:

由於物聯網裝置內的SIM卡更換不易,必需預載SIM卡於裝置中。當物聯網裝置生產國與銷售國家不同時,需要避免國際漫遊造成昂貴的連線成本或犧牲連線速度。

推展IoT服務在SIM的議題

在A國製造通訊模組、在B國組裝、到C國銷售、最後終端用戶在D國使用;在製造、配送、銷售、使用的環節中,都需要有連網能力來進行測試,物流管理以及加值服務的提供。

然而如果出廠時已經選定了一家電信公司且無法更換SIM卡,那麼在整個價值鏈的某一段裡,一定會發生昂貴的國際漫遊費用或過長時延。

IoT跨國應用的議題

朝向IPv6

啟用NAT

行動數據用戶的成長、IPv4位址的短缺,Y2011年啟用NAT

(Network Address Translation)技術,解決行動網路IP位址不足。

朝向All IPv6,除網路業者提供IPv4/IPv6環境外,視物聯網的成長需求、內容業者提供IPv6環境而定。

商用網路升級IPv6 目前IPv4以NAT技術尚可符合新增用戶連線IP位址需求,但面臨未來物聯網需求:

近程

業者新增設備同時提供IPv4/IPv6雙協定(Dual Stack),目前台灣大哥大網路已100% ready IPv4/IPv6 雙協定(Dual Stack)。

中程

市場聯網裝置、內容提供業者需求啟用IPv6,同時配發IPv4&IPv6位址,新創服務配發IPv6,減緩過渡期NAT的投資。

長程

內容服務業者與終端廠商逐步提供IPv6後,未來以IPv6為主的網路。

LTE推動IPv6可能遭遇問題

19

移動數據通信技術採用3GPP相關協議為主,在嚴格的規範下提升了設備的相容性與互通性,若手機規格/應用技術/網路架構其中有ㄧ未完全支援就有可能產生問題

3GPP針對IPv6規範的發展相對緩慢

4G在漫遊時處理因各業者支援不一

尚有許多搭配的系統需要配合IPv6修改,例如通信監察、緊

急服務(110,119,定位等)的處理
