Introduction

3GPP52.021Network Management (NM) procedures and messages on the A-bis interfaceRelease 17TS

(Background)

The use and general aspects of the A‑bis interface are given in specification 3GPP TS 48.051. The split of telecommunications functions and management procedures between BSC and BTS are defined in specification 3GPP TS 48.052. Specification 3GPP TS 48.056 defines Layer 2 of the signalling messages.

The general aspects of NM are defined in specification GSM 12.00. Qx interface and protocol stack are defined in specification GSM 12.01. GSM 12.06 provides the functional requirements supported by the present document. The NM procedures and messages to support these operations over the A‑bis interface are specified here. Specification GSM 12.20 provides the information model as seen on the OMC-BSC interface. Interworking between this model and the NM messages and procedures provided here is specified in GSM 12.22.
