With the advancement of technology, IPLOOK has taken the private network solution to new heights by offering a powerful combination of Evolved Packet Core (EPC), IP Multimedia Subsystem (IMS), and Mission-Critical Push-to-Talk (MCPTT) capabilities.

MCPTT被定义为一种运行在LTE网络上的全IP应用层服务，它使了用基于IMS域的实现方案，综合了大带宽、低延迟、易于大规模建网等众多优点，相比于现有的技术具有相当的优势。 MCPTT服务提供的是一种增强型的PTT服务，适用于执行关键任务的场景，支持鉴权、组附属、组管理、组呼、单呼、优先级呼叫、发言权控制、位置上报等功能。 MCPTT系统介绍. MCPTT系统由终端域、承载域、SIP核心域以及MCPTT应用域组成，如下图所示。 终端通过Relay中继接入到EPS …

2017年1月9日 · 2）MCPTT（Mission Critical Push To Talk）：目标是实现PTT端到端业务，主要规范集群服务器和终端应用层方面，利用LTE提供的GCSE和ProSe能力，在应用层设计呼叫控制过程，实现完善的语音集群功能。

end network architecture of a typical PS-LTE deployment. It depicts three primary domains: LTE Radio Access Network (RAN), LTE Core Network (CN), and the IP Multimedia Subsystem (IMS), which includes application servers f.

At its most basic, an MCPTX implementation involves the deployment of an Application Server (AS), which interfaces with the operator’s Evolved Packet Core (EPC) and is responsible for providing MCPTX functionality in conjunction with an MCPTX client application installed on end-user equipment.

2019年7月24日 · This paper analyzes the impact of the evolution of mobile broadband networks from 4G architectures towards 5G on Mission Critical Push-to-Talk (MCPTT) key performance indicators (KPIs).

Samsung’s experience in the deployment of next-generation Public Safety LTE networks (PS-LTE) and Mission Critical Push-to-X (MCPTX) services demonstrates that it is entirely possible to serve both sides of the equation, delivering on the core pillars of public safety communications while making available cutting-edge services and features that ...

The Mission Critical Services (MCX) is being designed to interoperate with legacy LMR networks for integrated MCPTT voice, MCVideo and MCData capabilities.

The purpose of the present test is to verify UE behaviour at LTE level when MCPTT services are enabled. Limited handling of MCPTT behaviour is provided only for the purpose of make the test handling possible. Detailed testing of the MCPTT services is specified in TS 36.579-2 [60].

Open5GS is a C-language Open Source implementation for 5G Core and EPC, i.e. the core network of LTE/NR network (Release-17)
