主頁（http://www.130131.com）：摩托羅拉系統(tǒng)和愛立信聯(lián)手發(fā)展下一代PTT通信

　　摩托羅拉系統(tǒng)和愛立信近日宣布，他們將通過LTE寬帶網絡整合、拓展傳統(tǒng)的無線通信方式，以便發(fā)展下一代PTT通信來滿足公共安全領域的市場需求。

　　愛立信、摩托羅拉系統(tǒng)和澳電信公司（Telstra）將以澳大利亞為試點來做下一代移動寬帶PTT通信的概念嘗試和推動；并將在全球各標準論壇上進行合作，以便形成完備的行業(yè)解決方案來滿足公共安全客戶的需求。

　　該合作集眾長于一身，屬于強強聯(lián)合——愛立信擁有便捷高效的網絡基礎設施；摩托羅拉系統(tǒng)在為公共安全提供任務關鍵通信上具有豐富的經驗；而Telstra擁有龐大的網絡資源和定義及部署下一代通信標準和性能的專業(yè)經驗。

　　下一代PTT通信是新興的、基于LTE的公共安全機構解決方案的重要組成部分。該技術將對由地面移動無線通信(LMR)網絡提供的關鍵業(yè)務性能進行補充，并且通過各種移動終端讓網絡覆蓋更多用戶。

　　當今公共安全環(huán)境的發(fā)展動態(tài)告訴我們，不斷引入的海量數(shù)據源需要結合傳統(tǒng)語音通信方能幫助公共安全機構做出更好和更快的決策。而這種綜合信息的提供，將有利于公共安全機構按照社會安全和工作效率最大化的原則來運用處理各種資源。

　　一方面，現(xiàn)今的LMR系統(tǒng)將繼續(xù)發(fā)揮重大作用；與此同時，下一代PTT與現(xiàn)有的TETRA和P25系統(tǒng)的交互操作，可以為公共安全機構在緊急情況下提供更為卓越的性能和服務。

　　摩托羅拉系統(tǒng)公司產品和服務部執(zhí)行副總裁Bruce Brda表示，摩托羅拉系統(tǒng)的參與將推進所需的標準和技術，以拓展維護公共安全的關鍵任務LMR網絡。“這個工程是我們打造智能公共安全的愿景的一部分，下一代移動智能——通過技術的調諧和融合——使公共安全機構在維護公共安全方面取得更為理想的效果。讓更多的公共安全維護者互聯(lián)互通可以幫助一線人員增加現(xiàn)場感知能力，提高工作效率。”

　　Telstra執(zhí)行董事MikeWright認為：“Telstra在定義和發(fā)展下一代PTT等服務的標準方面發(fā)揮著重要作用，未來該技術將為一線工作人員提供一個支持更多多媒體通信的平臺。”他還進一步表示：“通過Telstra LANES®（先進的LTE應急服務網絡）提供領先的LTE公共安全網絡性能是我們的主要目標和愿景。通過LANES®我們可以為任務關鍵通信用戶提供讓語音擴展到更多人員的優(yōu)秀解決方案。”

　　愛立信4G/5G 營業(yè)部的負責人Per Narvinger談到：“我們很高興與摩托羅拉系統(tǒng)公司一起合作，并樂意支持Telstra在澳大利亞市場上對下一代PTT通信業(yè)務的切入和嘗試。愛立信一直支持LTE作為公共安全機構通信的最好發(fā)展路徑，而此次合作是在該方向上的邁出的又一重要步伐。”

　　此次合作將為公共安全用戶提供基于標準的重要細節(jié)包括：

　　通過最小化時延以優(yōu)化PTT網絡延遲，提供優(yōu)質語音通信。

　　通過集成傳統(tǒng)的無線通信和寬帶網絡，實現(xiàn)靈活的群呼組呼管理。

　　通過LTE設備(如智能手機、平板電腦和臺式電腦)實現(xiàn)優(yōu)先呼叫。

　　隨著LTE網絡在澳大利亞的日益普及，公共安全機構將得益于下一代PTT業(yè)務提供的更多成員的接入和更廣的LTE網絡覆蓋范圍。Telstra計劃在2017年6月底將其LTE網絡在澳大利亞的普及率擴大至99%。

　　Next-Generation Push-to-TalkCommunications with Ericsson and Motorola Solutions

　　MotorolaSolutions (NYSE:MSI) and Ericsson (NASDAQ: ERIC) today （24 February,2016）announced that they will develop next-generationpush-to-talk communications for the public safety market, creating a way fortraditional radio communications to integrate and extend via LTE broadbandnetworks.

　　Ericssonand Motorola Solutions together with Telstra, will do a concept trial ofnext-generation mobile broadband push-to-talk communications in Australia andcollaborate in standards forums globally to develop an industry solution thatwill meet the requirements of public safety users.

　　Thepartnership brings together Ericsson’s flexible and efficient networkinfrastructure, Motorola Solutions’ depth of experience in providingmission-critical communications for public safety, and Telstra’s vast networkresources and expertise in defining and deploying next-generationcommunications standards and capabilities.

　　Next-generationpush-to-talk is an important component of emerging LTE-based public safetyagency solutions. This technology will complement the mission-criticalcapabilities provided by the Land Mobile Radio (LMR) networks that agenciesdepend on today and extend those networks to a greater number of users carryingsmart phones and other devices.

　　Thechanging dynamics of today’s public safety environment has seen theintroduction of a growing number of data sources that need to be combined withtraditional voice communications to help public safety agencies make better andfaster decisions. Delivering this combined information will help agencies tomanage their resources in a way that maximises community safety and workforceproductivity.

　　Whiletoday’s LMR systems will continue to play an important role for years to come,the interoperability of next-generation push-to-talk with existing TETRA andP25 systems will provide agencies with greater capacity in times of emergency.

　　BruceBrda, executive vice president Products and Services with Motorola Solutionssaid his company’s involvement would advance both the standards andtechnologies needed to extend the reach of public safety’s mission critical LMRnetworks.

　　“Thisproject is part of our vision for smart public safety, Next-Generation MobileIntelligence, that is helping agencies deliver better community safety outcomesthrough a dynamic mix of technologies. Connecting a greater number of publicsafety officials will help to increase situational awareness and efficiencyamong first responders in the field.”

　　MikeWright, Telstra Networks Group Managing Director said “Telstra plays a leadingrole in developing and defining the standards for new services includingnext-generation push to talk. In the future this technology will provide aplatform to deliver greater multi-media communications to front lineresponders.”

　　“Providinga leading LTE public safety capability is a key objective for Telstra with itsTelstra LANES® (LTE Advanced Network for Emergency Services) advanced networksolution. A mission-critical push to talk capability is part of our vision forpublic safety communications via LANES® and delivers our mission-criticalcustomers a compelling solution to extend voice to more of their staff.”

　　PerNarvinger Head of 4G/5G RAN, Ericsson’s said, “We are pleased to be workingwith our partner Motorola Solutions and to support Telstra’s early trials andintroduction of next-generation push-to-talk to the Australian market. Ericssonhas long supported LTE as the best path forward for public safety agencycommunications and this is another important step in this direction.”

　　Thecollaboration will provide standards-based features important to public safetyusers including:

　　Optimisedpush-to-talk latency to deliver voice communications with minimal delays.

　　Flexibletalk group management integrated across both radio and broadband networks.

　　Callpreemption for LTE devices such as smart phones, tablets and desk topcomputers.

　　Publicsafety agencies will benefit from providing more staff with access tonext-generation push-to-talk and greater coverage as LTE networks are extendedacross Australia. Telstra plans to reach coverage across 99 percent ofAustralia via its LTE networks by the end of June 2017。
