[摘要] 除了5G性能目标和基本功能要求包括在该规范中外,还定义了不同场景下(如城区宏蜂窝、偏远地区宏蜂窝、室内热点)及应用(如远程控制、监测、智能交通系统、触觉交互等)的5G网络性能指标。

  a&s智慧城市讯:3GPP SA WG1近日宣布完成了3GPP首个5G规范标准:《第五代移动通信系统的业务需求》。除了5G性能目标和基本功能要求包括在该规范中外,还定义了不同场景下(如城区宏蜂窝、偏远地区宏蜂窝、室内热点)及应用(如远程控制、监测、智能交通系统、触觉交互等)的5G网络性能指标。

  5G性能目标和基本功能的要求:

  1、5G应支持固定、移动、无线和卫星接入技术;

  2、5G应是一个可扩展的、可定制的网络,可以根据需求为多类服务及垂直市场定制(例如:网络分层、网络功能虚拟化);

  3、5G应面向从低数据物联网业务及高比特率多媒体业务提供高的资源利用效率;

  4、能源效率和电池的功率优化;

  5、5G应为第三方ISP以及ICP开放能力,比如可使得他们管理网片切片,并在移动通信运营商的业务托管环境中部署各种应用;

  6、5G应能支持通过中继UE(用户终端)把远端UE连接至5G网络,并应能保持直接连接和间接连接的连续性。

  并且,3GPP首个5G标准《5G业务需求》还定义了不同场景下(如城区宏蜂窝、偏远地区宏蜂窝、室内热点)及应用(如远程控制、监测、智能交通系统、触觉交互等)的5G网络性能指标。

  附“5G”业务需求全文:

  In Jeju South Korea, SA WG1 has completed its first normative specification on “Service requirements for the5G system” (TS22.261), which will now be submitted for approval at the Plenary meeting of the Service and System Aspects Technical Specification Group (TSG SA#75), 8-10 March 2017.

  The specification contains requirements on performance targets and basic capabilities - characterized by:

  Support for fixed, mobile, wireless and satellite access technologies

  A scalable and customizable network that CAN be tailored to requirements from multiple services and vertical markets (e.g., network slicing, Network Function Virtualization)

  Resource efficiency for services ranging from low data IoT services to high bitrate multimedia services

  Energy efficiency and battery power optimization

  Network capability exposure to allow 3rd party Internet Service Providers and Internet Content Providers to e.g. manage network slices, and deploy applications in the operator’s Service Hosting Environment

  Indirect connectivity from a Remote UE via a Relay UE to the network, and service continuity between indirect connections and direct connections.

  3GPP TS22.261 defines performance targets for different scenarios (e.g. urban macro, rural macro, indoor hotspot) and applications (e.g. remote control, monitoring, intelligent transport systems, and tactile interaction), for example:

  User experienced data rates vary, from 1 Gbps downlink and 500 Mpbs uplink for indoor hotspot environments to 50 Mbps downlink and 25 Mbps uplink for rural macro environments.

  Latency targets, an important performance indicator for 5G, are as low as 0,5 ms for tactile interaction.

  Capacity targets can be as high as 15 Tbps/km2 with 250 000 users/km2 for indoor hotspots such as office environments.

  The service requirements in the specification will now be used as inputs for the 5G normative work in other3GPP working groups.

  Release 15 specifications for the first phase of 5G will be ready in June 2018.
