08.523GPPBase Station Controller - Base Tranceiver Station (BSC-BTS) Interface - Interface PrinciplesTS
The use and general aspects of the A-bis interface are given in Technical Specification 3GPP TS 08.51.
The present document gives the principle basis for the rest of the specifications specifying the interface between the Base Station Controller, BSC, and the Base Transceiver Station, BTS, with its transceivers, TRX. These components together form the Base Station System, BSS. (The interface between MSC and the BSS is specified in Technical Specifications 3GPP TS 08.01 – 08.20).
The intention with this interface is to get a unified way of connecting remotely located BTSs/TRXs to a BSC allowing for the interconnection of BSCs and BTSs/TRXs from different manufacturers.
In order to keep the BTS as simple as possible, BTS contains only those functions which have to recide close to the radio interface.
The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
- References are either specific (identified by date of publication, edition number, version number, etc.) or non‑specific.
- For a specific reference, subsequent revisions do not apply.
- For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.
