PDSN

At the radio side, BTS communicates with AT over Um air interface. At the network side, BTS communicates with BSC over Abis interface. In the forward direction, BTS first receives data from BSC over Abis interface. It implements CDMA coding and data modulation by converting baseband signals into RF signals followed by power amplification and subsequent transmission over RFE and antennas.



f

BSS Networking

In the reverse direction, BTS receives weak radio signals from AT via the antenna feeder and RFE. It performs low noise amplification, down-conversion, CDMA signal decoding and demodulation, and sends the signals to BSC over Abis interface.

BSC has overall control of BSS and establishes connection with BTS over Abis interface and the Mobile Switching Center Emulation (MSCe), Media Gateway (MGW), Packet Data Service Node (PDSN), Broadcast Serving Node (BSN) and Dispatching Server Subsystem (DSS) connection over A/Ap interface. Netnumen™ M3 (ZXC10 BSSB) OMM (Operation and Maintenance Module) manages NEs and provides a standard interface to connect with upper-level NMC. It can be connected to the upper-level NMS via the standard CORBA, SNMP, FTP, or Telnet interface. BSS, MSCe, MGW and Public Switched Telephone Network (PSTN) work together to implement voice service and Short Messaging Service (SMS) function in the traditional circuit domain. BSS, PDSN work with Internet to implement data service in the packet domain that leads to implementation of other data services. Addition of several core network function entities enables delivery of EV-DO multicast services. BSS and DSS work together to implement digital trunking communication services. BSS and BSN work together to implement broadcasting service.

BSS supports multiple networking modes, includes:

Star Networking In star networking, BSC connects with each BTS directly through E1 link, satellite link or built-in Synchronous Digital Hierarchy (SDH) link, and each BTS represents a terminal device. Simplicity of this mode enables easy maintenance and engineering. Since signal transmission takes place with fewer intermediate links, transmission reliability is higher. Star networking commonly applies to more populated areas. Figure 3 illustrates BSS star networking.

Chain Networking In chain networking, several BTS interconnect to form a chain, and interface with BSC through BTS located at chain ends. In this mode, signal transmission takes place through intermediate nodes, resulting in low transmission reliability. This mode is suitable for less populated areas. Employing this networking mode reduces investment on transmission equipments. Chain networking is also applicable for sites with multiple BTS. Figure 4 illustrates BSS chain networking.

FIGURE 4 BSS CHAIN NETWORKING MODE

14



Ring Networking In ring networking mode, several BTS connect with BSC in series to form a ring. Figure 5 illustrates BSS ring networking.

FIGURE 5 BSS RING NETWORKING MODE

Hybrid Networking Hybrid networking is the combination of network topologies (star, chain and ring) implemented between BTS and BSC. Figure 6 illustrates BSS hybrid networking mode with star, chain and ring networking modes.

NetNumen™ M3 (ZXC10 BSSB) provides an alarm management tool for the maintenance personnel to monitor NEs (Network Elements) in the entire network, collect abnormal messages generated during NE running, and display these messages in forms like texts, graphics, sounds and light. In this way, the user can obtain the real-time information about the exceptional cases and handle them in time to ensure normal and reliable running of the BSS system.

Alarm Levels Based on the alarm severity, the alarm information can be classified into four Levels: 1, 2, 3 and 4, representing critical alarms, major alarms, minor alarms and warnings respectively.

Level 1 alarm is critical alarms and requires immediate handling. Level 2 alarm is major alarms that can affects system functionality and requires on time handling. Level 3 alarm is minor alarms and reminds the maintenance personnel to remove the possible faults. Level 4 alarm is warning alarms, which keeps the maintenance personnel aware of equipment running state.
