1 Scope
The present document defines the application protocol on the eLSA interface, between eLSA Controller (eLC) and
1
eLSA Repository (eLR) (eLSA protocol) [i.3], and the content of the eLSA Spectrum Resource Availability
1
Information (eLSRAI) conveyed by this protocol. It is based on the System Requirements defined in ETSI
TS 103 652-1 [i.2] and the System Architecture and High-Level Procedures defined in ETSI TS 103 652-2 [i.3].
The present document supports the operation of MFCNs operated by vertical sector players under the evolved Licensed
Shared Access (eLSA) system, aimed at enabling the automatic provision of local spectrum access rights to vertical
sector players through:
• licenses acquired in advanced from the NRA and provided by the eLSA procedures; and/or
• licenses/leases acquired and provided by the eLSA procedures.
The operation of eLSA is frequency agnostic. The application of eLSA to concrete frequency bands depends on national
regulatory decisions.

3 Definition of terms, symbols and abbreviations
3.1 Terms
For the purposes of the present document, the following terms apply:
allowance zone: geographical area within which an eLSA Licensee can operate radio transmitters on its assigned
spectrum resource
NOTE 1: An allowance zone is defined using specific measurement quantities and thresholds, e.g. a maximum field
strength level expressed in dBµ V/m/MHz, along the border of its geographical area.
NOTE 2: An allowance zone is normally applicable for a defined frequency range and time period.
detached operation mode: operation mode where a VSP operates a MFCN without a permanent network connection
NOTE: The point of detachment between the VSP and the eLSA system can be located at the eLSA and/or the
1
eLSA interface.
4
eLSA spectrum resource availability information: information provided to a Licensee, which conveys the eLSA
spectrum resource that may be used by the Licensee, and the respective operational conditions or restrictions
eLSRAI context: set of zones and their parameters that are to be maintained by the nodes (eLC a
