ETSI ETSI TS 103 235 V1.1.1 (2015-10)6 1 Scope The present document specifies the system architecture for operation of mobile broadband service in the 2 300 MHz - 2 400 MHz band under Licensed Shared Access (LSA) i.2 and i.3, aimed at enabling access for mobile/fixed com
23、munication 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.1. Application to other bands is not precluded and depends on future regulatory decisions. The documented sy
24、stem architecture includes definition of the logical elements, reference points and functions supported by the architecture, and the definition of the procedures and procedure flows. The present document has been developed following, and in accordance with, the System Requirements for LSA as documen

40、2 Logical Elements LSA Repository (LR): The LR supports the entry and storage of information describing Incumbents usage and protection requirements 1. It is able to convey the related availability information to authorized LSA Controllers, and is also able to receive and store acknowledgement infor
41、mation received from the LSA Controllers. The LR also provides means for the NRA to monitor the operation of the LSA System 1, and to provide the LSA System with information on the Sharing Framework and the LSA Licensees. The LR ensures that the LSA system operates in conformance with the Sharing Fr
42、amework i.2 and the licensing regime, and may in addition realize any non-regulatory details of the Sharing Arrangement 1. LSA Controller (LC): The LC is located within the LSA Licensees domain, and enables the LSA Licensee 1 to obtain LSA spectrum resource availability information from the LR, and
43、to provide acknowledgment information to the LR. The LC interacts with the Licensees MFCN in order to support the mapping of availability information into appropriate radio transmitter configurations, and receive the respective confirmations from the MFCN. 4.3 Reference Points LSA1: Reference point
44、between LR and LC. LSA2: Reference point for Administration/NRA interaction with the LR. Some of the functionality associated with this reference point is described in annex B. LSA3: Reference point for Incumbent interaction with the LR. Some of the functionality associated with this reference point
45、 is described in annex B. 4.4 High Level Functions 4.4.0 Introduction This clause lists and describes the high level functions performed by the LSA System. The high level functions cover the aspects of LSA System operation in line with requirements of ETSI TS 103 154 1. 4.4.1 Information Entry Funct
46、ion Allows the entry and storage of information that is needed for the operation of the LSA System, including the following: Sharing Framework information (set of sharing rules or sharing conditions for the band, information on spectrum that can be made available for shared use and the corresponding
47、 technical and operational conditions for its use, identification of incumbents). ETSI ETSI TS 103 235 V1.1.1 (2015-10)9 LSA License information (Licensee identity and related information). Sharing Arrangement information for each Incumbent and Licensee (set of practical details for sharing an LSA s
48、pectrum resource, whereby LSA spectrum resource may be used by Incumbent or LSA Licensee). Incumbents LSA spectrum resource usage and protection requirements. The function also supports the verification of inputs (consistency with Sharing Framework/Arrangement). 4.4.2 Information Processing Function
49、 This function supports the derivation of LSA spectrum resource availability information for each Licensee, to be provided to the Information Exchange function for forwarding to the respective Information Mapping function of the LSA Licensee. The LSA spectrum resource availability information is derived based on the data collected by the Information Entry Function. The function further supports the processing of Licensee acknowledgment information. The above functionality also includes support for multiple Incumbents and multipl
