主页（http://www.pttcn.net）：摩托罗拉系统和爱立信联手发展下一代PTT通信

　　摩托罗拉系统和爱立信近日宣布，他们将通过LTE宽带网络整合、拓展传统的无线通信方式，以便发展下一代PTT通信来满足公共安全领域的市场需求。

　　爱立信、摩托罗拉系统和澳电信公司（Telstra）将以澳大利亚为试点来做下一代移动宽带PTT通信的概念尝试和推动；并将在全球各标准论坛上进行合作，以便形成完备的行业解决方案来满足公共安全客户的需求。

　　该合作集众长于一身，属于强强联合——爱立信拥有便捷高效的网络基础设施；摩托罗拉系统在为公共安全提供任务关键通信上具有丰富的经验；而Telstra拥有庞大的网络资源和定义及部署下一代通信标准和性能的专业经验。

　　下一代PTT通信是新兴的、基于LTE的公共安全机构解决方案的重要组成部分。该技术将对由地面移动无线通信(LMR)网络提供的关键业务性能进行补充，并且通过各种移动终端让网络覆盖更多用户。

　　当今公共安全环境的发展动态告诉我们，不断引入的海量数据源需要结合传统语音通信方能帮助公共安全机构做出更好和更快的决策。而这种综合信息的提供，将有利于公共安全机构按照社会安全和工作效率最大化的原则来运用处理各种资源。

　　一方面，现今的LMR系统将继续发挥重大作用；与此同时，下一代PTT与现有的TETRA和P25系统的交互操作，可以为公共安全机构在紧急情况下提供更为卓越的性能和服务。

　　摩托罗拉系统公司产品和服务部执行副总裁Bruce Brda表示，摩托罗拉系统的参与将推进所需的标准和技术，以拓展维护公共安全的关键任务LMR网络。“这个工程是我们打造智能公共安全的愿景的一部分，下一代移动智能——通过技术的调谐和融合——使公共安全机构在维护公共安全方面取得更为理想的效果。让更多的公共安全维护者互联互通可以帮助一线人员增加现场感知能力，提高工作效率。”

　　Telstra执行董事MikeWright认为：“Telstra在定义和发展下一代PTT等服务的标准方面发挥着重要作用，未来该技术将为一线工作人员提供一个支持更多多媒体通信的平台。”他还进一步表示：“通过Telstra LANES®（先进的LTE应急服务网络）提供领先的LTE公共安全网络性能是我们的主要目标和愿景。通过LANES®我们可以为任务关键通信用户提供让语音扩展到更多人员的优秀解决方案。”

　　爱立信4G/5G 营业部的负责人Per Narvinger谈到：“我们很高兴与摩托罗拉系统公司一起合作，并乐意支持Telstra在澳大利亚市场上对下一代PTT通信业务的切入和尝试。爱立信一直支持LTE作为公共安全机构通信的最好发展路径，而此次合作是在该方向上的迈出的又一重要步伐。”

　　此次合作将为公共安全用户提供基于标准的重要细节包括：

　　通过最小化时延以优化PTT网络延迟，提供优质语音通信。

　　通过集成传统的无线通信和宽带网络，实现灵活的群呼组呼管理。

　　通过LTE设备(如智能手机、平板电脑和台式电脑)实现优先呼叫。

　　随着LTE网络在澳大利亚的日益普及，公共安全机构将得益于下一代PTT业务提供的更多成员的接入和更广的LTE网络覆盖范围。Telstra计划在2017年6月底将其LTE网络在澳大利亚的普及率扩大至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。
