3 Interface specification objectives

08.513GPPBase Station Controller - Base Tranceiver Station (BSC-BTS) Interface General AspectsTS

The BSC to BTS interface specifications should allow the following:

(I) Connection of various manufacturers BTS/TRX to the same BSC, according to the location of the transcoder.

(II) The use of several manufacturers BSC to the same type of BTS/TRX, according to the location of the transcoder.

(III) The use of the same BTS/TRX in any PLMN, according to the location of the transcoder.

(IV) The use of the same BSC in any PLMN.

(V) Separate evolution of BSC and BTS/TRX technology.

(VI) Separate evolution of O & M facilities.

(VII) Sub-multiplexing of speech channels on a 64 kbit circuit.

(VIII) Evolution towards lower speech coding rates.

(IX) Location of transcoders either in BSC or in BTS.

(X) Support of all services defined in the 02 series of 3GPP Technical Specifications.

(XI) A stepwise expansion of capacity in a BTS.

(XII) Different physical solution of the various equipment in the BTS.

(XIII) Support of a single TRX forming a BTS.

(XIV) Support of a set of TRX’S forming a BTS.

(XV) Support of a BTS as one entity.
