ETSI TS 103 379定义了LSA控制器（LC）和LSA之间的LSA1接口上的应用协议 存储库（LR）[i.2]（LSA1协议），以及LSA频谱资源可用性信息的内容 （LSRAI）通过本协议传达。它基于ETSI TS 103 154[i.1]和 ETSI TS 103 235[i.2]中定义的系统架构和高级程序。本文件支持移动宽带服务在2 300 MHz-2 400 MHz频段下的运行 许可共享接入（LSA），旨在实现这些地区的移动/固定通信网络（MFCN）接入 CEPT国家，可预见进入该波段，但由于现有条件的限制，无法在没有限制的情况下提供 使用，如ETSI TR 103 113[i.3]所述。不排除应用于其他波段，这取决于未来 监管决定。

ETSI TS 103 379 defines the application protocol on the LSA1 interface, between LSA Controller (LC) and LSA Repository (LR) [i.2] (LSA1 protocol), and the content of the LSA Spectrum Resource Availability Information (LSRAI) conveyed by this protocol. It is based on the System Requirements defined in ETSI TS 103 154 [i.1] and the System Architecture and High Level Procedures defined in ETSI TS 103 235 [i.2].The present document supports the operation of mobile broadband service in the 2 300 MHz - 2 400 MHz band under Licensed Shared Access (LSA), aimed at enabling access for mobile/fixed communication networks (MFCNs) in those CEPT countries where access to the band is foreseen but cannot be provided without restrictions due to Incumbent usage, as documented in ETSI TR 103 113 [i.3]. Application to other bands is not precluded and depends on future regulatory decisions.
