标准2025此项规范有助于实现频谱共享，提高服务质量。ETSI可重构无线电系统技术委员会（ETSI TC RRS）宣布许可共享访问（LSA）规范已经制定完成。
此项规范有助于实现LSA被许可方和现存频谱被许可方之间的频谱共享协调，从而确保服务质量（QoS）。
最近制定的ETSI TS 103 379规范公布了在2300MHz-24MHz频段内执行许可共享访问的信息元素和协议。该文件定义了名为LSA1协议的应用协议，用于探讨LSA控制器和LSA存储库之间的关系，以及该协议传达的信息内容。
这个新规范的推出标志着ETSI TC RRS系列规范的制定完成，该系列规范为LSA存储库和LSA控制器的互操作性开辟了道路，从而支持初始目标频段（2300MHz-24MHz）中的LSA部署。根据未来的监管要求，并不排除LSA部署会在其他频段扩展。顾及未来要求和其他功能正是发布新版LSA规范的目的。
ETSI TC RRS主席马尔库斯.慕克（Markus Mueck）表示，“ETSI的LSA活动是欧盟委员会、欧洲邮电管理委员会（CEPT）和欧洲电信标准协会之间高效协作的完美实例。欧盟委员会M/512框架委托书有效解决了法规和标准方面的挑战，为欧洲的许可共享访问技术提供了现存的一揽子方案。此外，ETSI的规范大大影响了其他地区的相关活动，如美国联邦通信委员会（FCC）关于3550MHz-3700MHz频段内公民宽带无线服务的报告。基于频谱共享的许可共享访问有望成为监管机构工具箱中的关键组成，从而解决未来5G频谱需求。”
在LSA体系结构中，LSA存储库包含频谱资源可用性的信息，而这些信息依取决于现有用户所使用的频谱权限，并根据每个国家的具体监管制度而定。LSA控制器安置在网络运营商的域中，以确保网路配置遵从LSA存储库发射的指令。因此，LSA1协议提供了一种可靠灵活的手段，确保控制器和存储库之间的信息同步，包括更改任何限制之后，仍能确保LSA控制器遵从LSA存储库的指令。
ETSI的工作响应了欧盟委员会关于可重构无线电(RRS)的M/512委托书，并紧跟欧洲邮电管理委员会(CEPT)工作，特别是关于“许可共享访问”的嵌入式通信信道205报告。此项工作完成并补充了ETSI的现有规范。
现有规范包括：
ETSI TR 103 113：系统参考文件（SRdoc），许可共享访问管理体制下，2300MHz-2400MHz频段内的移动宽带业务
ETSI TS 103 154：许可共享访问下，2300MHz – 2400MHz频段内的移动宽带系统的运行系统要求
ETSI TS 103 235：在2300MHz – 2400MHz频段内，许可共享访问操作的系统架构和高级程序
此外，为解决地区高品质无线网络的不同技术可能，共享临时访问频谱，ETSI可重构无线电系统技术委员会已经开展了新工作，技术报告预计将在今年完成。

ETSI releases specifications for Licensed Shared Access
Enabling spectrum sharing and improved Quality of Service
The ETSI Technical Committee for Reconfigurable Radio Systems (TC RRS) has announced the completion of the specification for the support of Licensed Shared Access (LSA).
This provides a means to enable spectrum sharing coordination between LSA licensees and existing spectrum licensees, thereby ensuring Quality of Service (QoS).
The recently completed specification, ETSI TS 103 379 addresses information elements and protocols for the operation of Licensed Shared Access in the 2 300 MHz – 2 400 MHz band. The document defines the application protocol, also known as LSA1 protocol, on the interface between the LSA Controller and the LSA Repository, and the content of the information conveyed by this protocol.
With this new specification, ETSI TC RRS completes a set of specifications that opens the way for interoperable implementation of LSA Repositories and LSA Controllers to support LSA deployments in the initial target band (2 300 MHz – 2 400 MHz). Extensions to other bands are not precluded, in response to future regulatory requirements. It is the intention to take such future requirements as well as additional features into consideration when starting a new release of the LSA specifications.
“ETSI’s LSA activities are a perfect example of the efficient interaction between the European Commission, CEPT and ETSI. Within the EC mandate M/512 framework, the regulation and standards challenges were efficiently addressed, leading to a ready-to-use package for Licensed Shared Access technology in Europe. Furthermore, ETSI’s specifications have substantially influenced related activities in other regions, such as the Federal Communications Commission’s (FCC) Report and Order on the Citizens Broadband Radio Service in the 3 550 – 3 700 MHz band,” says Markus Mueck, chairman of ETSI TC RRS. “Licensed Shared Access based spectrum sharing is expected to be a key element in the tool box of regulatory administrations in order to address future 5G spectrum needs.” he adds.
In the LSA architecture, the LSA repository contains information on spectrum resource availability, which is dependent on existing current holder of spectrum rights of use required usage and in accordance with each country’s specific regulatory regime. The LSA Controller resides in the network operator’s domain to ensure that the network configuration complies with the instructions received from the LSA Repository. The LSA1 protocol thus provides a reliable and flexible means to ensure that the information is synchronized between controller and repository, including confirmation of compliance by the LSA Controller after any change of restrictions.
The ETSI work was initiated in response to the European Commission’s Mandate M/512 on RRS, and closely followed related CEPT work, particularly the ECC Report 205 on “Licensed Shared Access”. It completes and complements existing ETSI specifications including:
ETSI TR 103 113: System Reference document (SRdoc); Mobile broadband services in the 2 300 MHz – 2 400 MHz frequency band under Licensed Shared Access regime
ETSI TS 103 154: System requirements for operation of Mobile Broadband Systems in the 2 300 MHz – 2 400 MHz band under Licensed Shared Access (LSA)
ETSI TS 103 235: System architecture and high level procedures for operation of Licensed Shared Access (LSA) in the 2 300 MHz – 2 400 MHz band
In addition, ETSI TC RRS has started new work to address the different technical possibilities for local high-quality wireless networks to access spectrum temporarily on a shared basis. A Technical Report will be finalized during this year.
