1.1.2、GSM/UMTS Radio Access Network

Abstract This chapter briefly introduces the GSM/UMTS radio access network. A mobile telecommunication system consists of a Radio Access Network (RAN), a Core Network (CN), and User Equipment (UE), as shown in Figure1. ZXSDR BS8900A GU360, serving as a base station (BTS/Node B), can be deployed in a GSM/UMTS radio access network, which supports both GSM and UMTS technologies. BTS/Node B and BSC/RNC constitute a Base Station Subsystem (BSS). ZXSDR BS8900A GU360 can also work with a Remote Radio Unit (RRU). Figure1 GSM/UMTS Radio Access Network

Core Network A Core Network (CN) comprises physical entities that provide network features and telecommunications services. It manages local information of subscribers, controls network and service functions, and transfers signalling and subscriber information.

Radio Access Network Different types of radio access networks can be deployed, depending on the supported technologies. •

A GSM radio access network consists of Base Station Controller (BSC) and Base Transceiver Station (BTS). It is between Mobile Station (MS) and the Core Network (CN).

•

A UMTS radio access network consists of Radio Network Controller (RNC) and base station (Node B). It is between User Equipment (UE) and the CN. RNC, Node B, and UE are terms used in UMTS equivalent to BSC, BTS, and MS used in GSM.

Radio Network Controller/Base Station Controller A RNC/BSC, connecting to the CN and Node B/BTS, manages radio links and optimizes radio resources. One RNC/BSC can manage multiple Node Bs/BTSs.

Base Station A base station (Node B/BTS), provides radio resources, and transmits and receives radio signals. It consists of BaseBand Unit (BBU) and Radio Frequency Unit (RFU), which implement different functions. •

BBU: This unit implements the processing of baseband signals, including encoding/decoding, multiplexing/demultiplexing, spreading/despreading, and channel mapping.

•

RFU: This unit receives and transmits radio signals. A Remote RF Unit (RRU) refers to an RFU mounted near an antenna, which is far away from the base station or BBU.

Interfaces 3GPP specifies the following open interfaces for the GSM/UMTS radio access network. •

Iu interface: This interface connects an RNC to the CN.

•

Iur interface: This interface connects two RNCs. It allows data transfer during soft handover of a UE between RNCs.

•

Iub interface: This interface connects a Node B and an RNC.

•

Uu interface: This interface connects a UE and a Node B.

Ventilation in BC8910A A heat exchanger is used to transfer the heat outside of the BC8910A cabinet. A rectifier implements the horizontal ventilation in the cabinet from front to rear. The BBU and transmission equipment in the BC8910A cabinet implements the horizontal ventilation from left and right.

Ventilation in PC8910A The fans are used to dissipate the heat in PC8910A.
