1 Overview In general, GSM/EDGE/UMTS system consists of Core Network (CN), Radio Network Subsystem (GERAN/UTRAN) and Mobile Station/User Equipment (MS/UE). GERAN/UTRAN includes 2 network elements, base station and BSC/RNC. The conventional 2G/3G BTS connects to BSC/RNC or MS/UE via Abis/Iub or Um/Uu interface respectively. Figure 1 shows a conventional GSM/EDGE/UMTS network system.

In the Fig 1, GPRS/EDGE and UTRAN are 2 separated radio networks. When ZTE 2G/3G dual-mode base station BS8800 is introduced, the 2G/3G radio networks will be converged into one and this will decrease the network construction cost greatly.

2 Highlight Features ZXSDR BS8800 GU360 (hereafter BS8800) is one of multi-carrier, multi-mode indoor macro base station in ZXSDR BTS series. By applying advanced MicroTCA platform and SDR technology, BS8800 can directly support GPRS/ EDGE/ Enhanced EDGE/ UMTS/ HSPA and HSPA+ simultaneously.

Its main advantage is that can be configured to a GERAN BTS, or a UTRAN Node B, or a G/W dual-mode BTS by software reconfiguration only and no required to add any hardware.

It develops a new solution for GSM/UMTS integrated network and network evolution. It decreases the mobile network construction and operation cost.

BS8800 can be applied in dense urban, urban, suburban, rural area, highway or indoor environment and can fully meet operators’ requirements in different stages and scenarios.

It has the following characteristics:

2.1 Smooth Evolution BS8800 software and hardware support full-feature EDGE and UMTS/HSPA and satisfy operators’ future needs for data service. In the future evolution to EDGE+ and HSPA+, only software upgrade is needed.

The MicroTCA architecture supports maximal 10Gbps data throughput and 20MHz radio frequency. It enables BS8800 to be also capable for LTE application.

2.2 Easy Installation BS8800 has small dimension: 1200mm * 600mm * 450mm (H*W*D).

Front wiring design enables against wall installation and conveniently maintenance.

2.3 Evolution to IP RAN BS8800 is developed based on the ZTE unified MicroTCA platform. GE/FE interfaces are provided. Smooth evolution and upgrade to IP RAN can be conveniently achieved.

2.4 Smooth Expansion Each BS8800 Radio Unit (RU) has the capability to support 6 GSM carriers or 4 UMTS carriers (max. 6 RUs can be installed for a full configuration). If GSM and UMTS are



configured at the same time, each radio unit supports 4 GSM carriers plus 1 UMTS carrier as an example.

2.5 Green Power Doherty, DPD and MCPA technologies are applied in ZTE power amplifier development for the improved PA efficiency.

With S666 GSM or S222 UMTS configuration, BS8800 power consumption is less than 900W – only half of conventional macro base station.

2.6 Rich Interfaces BS8800 provides E1/T1, E3/T3, STM-1 and GE interfaces for Abis/Iub connection and supports various transmission networking such as SDH network, IP networking or splitting transmission.

Between BS8800 RF units and baseband the 12 pair of 1.25G CPRI interfaces provided.

2.7 Flexible Dual-mode Networking BS8800 architecture makes it very flexible to meet GSM/UMTS inter-working requirements in different scenarios. BS8800 supports GSM900+GSM1800 hybrid networking and zero TCO from 2G to 3G evolution. It can be configured only to support GSM in the initial stage; UMTS 2100M can be supported by adding RU modules. In this way, GSM/UMTS co-existence can be realized perfectly. Also GSM900+UMTS900 can be supported with correspond software configuration.

• Network upgrade from GSM900 to GSM900+GSM1800

BS8800 supports 6 RU modules. By adding 3 RU-1800, GSM900+GSM1800 can be supported and the capacity is GSM900 S666 plus GSM1800 S666 in one cabinet.

• Network upgrade from GSM900 to GSM900+UMTS2100

In network evolution, based on the existing GSM900 network, UMTS2100 network can be constructed by adding 3 RU60-2100 modules and corresponding baseband resource. This is the most economic 2G to 3G evolution step in which main control module, transmission module and power are shared.

• Network upgrade from GSM900/1800 to GSM900/1800+UMTS900/1800

In BS8800, RU is designed to support UMTS, GSM with different software configuration. So in the network evolution, GSM900 can first evolve to support GSM900+UMTS900, and later complete UMTS900 with only software reconfiguration. The GSM1800 system has the same feature to support dual-mode in 1800 spectrum.

Software versions existing in the base station can be activated directly by the software or through software test.

• Alarm Management

The alarm management system monitors the running states of the base stations; displays dynamically the rack structure of the foreground module; collects abnormal information of the boards, links, database and server in real time. These functions make it convenient for operation and maintenance personnel to analyze, make judgment, and implement maintenance and repair.

Information collected by the alarm management system includes notification, alarm and alarm recovery.

The alarm management system synchronizes alarms, reports historical alarms and current alarms, and sets and queries alarm shielding.

• Configuration Management

Configuration management implements equipment configuration and radio configuration.

• Log Management

NetNumen M31 system provides the log management function. Any operation performed by an operator is recorded automatically in some modes by the system. Thus, the operation maintenance personnel can query historical operation records in some special cases (such as abnormal system operations). Log records are saved in the NM database server.
