System Functions
This chapter discusses the functions of the ZXG10 OB06 (V1.0), including
RF, baseband processing, signaling processing, O&M, and ultra-distance
coverage.
Overview
The OB06 receives the management and controls from BSC. It works with
the BSC to manage radio resources and radio network, control the
establishment, connection and disconnection of the radio connections
between MS and OB06, control the access, handover and paging of MS,
provide voice coding, transcoding and rate adaptation functions, provide
the adaptation and interconnection functions of GPRS services, and
implement the operation and maintenance functions of the BSS.
OB06 has the following four major functions to implement the above
service functions:
1. RF function: Implementing the radio connections between the MS and
BTS.
2. Baseband processing function: Providing voice coding, transcoding and
rate adaptation functions, including the processing of the GPRS part.
3. Based on the BSC instructions, controlling the establishment,
connection and disconnection of the radio connections between MS and
BTS, and controlling the access, handover and paging of MS, including
the processing of the GPRS part.
4. Operation and maintenance (O&M) function: Providing an O&M agent
for the BSC, managing radio resources and radio network and
implementing the O&M functions for OB06 subsystems.
Major RF Functions
The RF function of the OB06 meets the requirements of the GSM 05.05
protocol, featuring the advantages of high sensitivity, flexible configuration
and easy O&M, as briefed below.
