摩托罗拉体系和爱立信近日宣告，他们将经由进程LTE宽带收集整合、拓展传统的无线通讯体式样式，以便生长下一代PTT通讯来知足群众安稳范畴的市场需求。

爱立信、摩托罗拉体系和澳电信公司（Telstra）将以澳大利亚为试点来做下一代挪动宽带PTT通讯的意见实验和推动；并将在环球各类型论坛上举行协作，以便构成完整的行业处理设想来知足群众安稳客户的需求。

该协作集众善于一身，属于强强联合——爱立信具有轻易高效的收集基础设施；摩托罗拉体系在为群众安稳供应义务症结通讯上具有雄厚的履历；而Telstra具有严重的收集资本和界说及布置下一代通讯类型和机能的专业履历。

下一代PTT通讯是新兴的、基于LTE的群众安稳机构处理设想的重要构成部分。该手艺将对由地面挪动无线通讯(LMR)收集供应的症结营业机能举行增补，而且经由进程种种挪动终端让收集掩饰更多用户。

当今群众安稳状态的生长动态照顾我们，赓续引入的海量数据源须要连系传统语音通讯方能资助群众安稳机构做出更好和更快的决议想象。而这类综合信息的供应，将有利于群众安稳机构遵循社会安稳和事变效能最大化的准绳来应用措置惩罚种种资本。

一方面，当今的LMR体系将继承施展严重作用；与此同时，下一代PTT与现有的TETRA和P25体系的交互安排，能够为群众安稳机构在紧急状态下供应更加卓着的机能和效能。

摩托罗拉体系公司产物和效能部实行副总裁Bruce Brda走漏显现，摩托罗拉体系的介入将推动所需的类型和手艺，以拓展珍重群众安稳的症结义务LMR收集。“这个工程是我们打造智能群众安稳的愿景的一部分，下一代挪动智能——经由进程手艺的调谐和融会——使群众安稳机构在珍重群众安稳方面获得更加志向的结果。让更多的群众安稳珍重者互联互通能够也许资助一线职员增添现场感知才能，提高事变效能。”

Telstra实行董事MikeWright以为：“Telstra在界说和生长下一代PTT等效能的类型方面施展着重要作用，将来该手艺将为一线事变职员供应一个支撑更多多媒体通讯的平台。”他还进一步走漏显现：“经由进程Telstra LANES®（先进的LTE应急效能收集）供应争先的LTE群众安稳收集机能是我们的重要目的和愿景。经由进程LANES®我们能够为义务症结通讯用户供应让语音扩展到更多职员的优异处理设想。”

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体系公司一同协作，并宁愿支撑Telstra在澳大利亚市场上对下一代PTT通讯营业的切入和实验。爱立信一向支撑LTE作为群众安稳机构通讯的最好生长蹊径，而此次协作是在该方向上的迈出的又一重要步伐。”

此次协作将为群众安稳用户供应基于类型的重要细节网罗：

• 经由进程最小化时延以优化PTT收集耽搁，供应优异语音通讯。

• 经由进程集成传统的无线通讯和宽带收集，完成天真的群呼组呼治理。

• 经由进程LTE装备(如智能手机、平板电脑和台式电脑)完成优先招呼。

跟着LTE收集在澳大利亚的日趋提高，群众安稳机构将得益于下一代PTT营业供应的更多成员的接入和更广的LTE收集掩饰局限。Telstra想象在2017年6月尾将其LTE收集在澳大利亚的提高率扩展至99%。

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。
