33、 This clause describes the general WSD GLDBs architecture as well as the reference model of the logical entity, the GLDB, involved in the scope. The architecture shows the relationship of logical entities and the logical interface as detailed in the following clauses. The reference model shows the a
34、bstract architecture of components of logical entities and the logical interface. ETSI ETSI TS 103 143 V1.1.1 (2015-01)74.2 Architecture Figure 4.1 shows the instance of the G-G logical interface. The interface is used for the information exchange between GLDBs for enabling the operation of White Sp
35、ace Devices (WSDs) for the protection of the incumbent service. Figure 4.1: Architecture 4.3 Reference model of GLDB Figure 4.2 shows an architectural view of a GLDB emphasizing the separation of GLDB into Database function, Geo-location function and G-G Interface function. A function can access the
36、 services provided by another function via a corresponding Service Access Point (SAP). A GLDB exchanges information with another GLDB by accessing communication services via the Com-SAP. The DB-SAP is used by the G-G Interface function to access the services provided by the Database function such as
37、 registration of CRS and provision of incumbent information. The GL-SAP is used by the G-G Interface function to access the services provided by the Geo-location function such as the calculation of location specific EIRP that a WSD in a CRS can use in a frequency band. The Com-SAP is used by the G-G
38、 Interface function to access communication services provided by communication function for the information exchange with another G-G interface function. Note that the G-G interface function inside the GLDB uses the services provided at the above three SAPs to realize the logical interface between d

42、 of reference model for the information exchange between GLDBs using the G-G logical interface 5 Reference Points 5.1 Reference point: Logical interface between GLDBs Figure 5.1: Reference point for information exchange between GLDBs Figure 5.1 shows the reference point between GLDBs which is the G-
43、G logical interface between the GLDBs for enabling the operation of White Space Devices (WSDs) for the protection of the incumbent service. Specifically, the reference point enables one GLDB to interface with other GLDBs in order to guaranty that the operations of CRS managed by one GLDB satisfy the
44、 protection requirements of incumbents such as the Terrestrial Broadcasting Service registered in different GLDBs as specified by respective regulations. 5.2 Reference point requirements The following requirements do not mandate that GLDB implements any specific calculation methods. The reference po
45、int shall support information exchange between GLDB A and GLDB B to allow GLDB A to discover its affecting/neighbouring GLDB B. The reference point shall support information exchange between GLDB A and GLDB B to allow GLDB A to obtain necessary information to determine the available spectrum for a C
46、RS managed by GLDB A while satisfying the protection requirements of incumbents registered in GLDB B under the regulatory domain of GLDB B. The reference point shall support information exchange between GLDB A and GLDB B to allow GLDB A to provide information about a CRS under its management to GLDB
47、 B to allow GLDB B to calculate the interference to incumbents registered in GLDB B. ETSI ETSI TS 103 143 V1.1.1 (2015-01)9 The reference point shall support information exchange between GLDB A and GLDB B to allow GLDB A to obtain information about the CRSs that are managed by GLDB B that affect the
48、 interference to incumbents registered in GLDB A. Those CRSs may create interference below the interference reference field strength at a given location probability of the incumbents that are registered in GLDB A. However, they may still contribute adversely when considering aggregate/cumulative int
49、erference (see also section A11.1.1.4 of ECC report 186 i.2). 6 High Level Procedures: Overview of information exchange between different GLDBs related Architecture 6.1 Basic Procedures 6.1.1 Incumbents information sharing procedure Subject to regulatory agreements, a GLDB can send the information related to its registered incumbents to other GLDBs. This procedure populates the incumbents information among GLDBs so that each GLDB can determine the available channels of CRSs independently of other GLDBs and protect the incumbents registered in different
