BSSB Position in a Network Figure 1 describes the BSS position in a typical network. The BSS location is between Access Terminal (AT) and Core Network (CN), and constitutes the Access Network (AN) that processes radio signals, terminates radio protocols and connects MS with the core network.


1


FIGURE 1 - BSS POSITION IN THE NETWORK

The BSS comprises Base Station Controller (BSC) and Base Transceiver System (BTS). BSS establishes communication with AT over the Um interface and communicates with the core network through the corresponding A interface. V5 interfaces BSC and local exchange (not shown in the figure above). 1. The BTS lies between MS and BSC, and is responsible for bridging the gap between AT and core network. i. On the radio side, BTS communicates with AT over CDMA air

interface. ii. On the network side, BTS communicates with BSC over Abis

interface. iii. 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. iv. In the reverse direction, BTS receives weak radio signals from AT

over 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. 2. 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) and Dispatching Server Subsystem (DSS) connection over A interface. ZXCOMC or OMC for BSS O&M lies on the BSC side. OMC manages NEs

Operation and Maintenance System This chapter explains: ZXC10 BSSB OMC structure and functions. BSS implements system O&M functions through OMC. OMC software follows client/server architecture. The application server receives requests from clients, implements service and database processing, and sends requests to BSS. It then processes and returns results to the client, realizing O&M functions. The server manages all service functions in a centralized manner, and handles processing, which the client cannot realize.

System Architecture OMC provides network management at each level like Provincial Operation & Maintenance Center (POMC), Local Operations and Maintenance Center (LOMC), and Operation and Maintenance Module (OMM).

OMM Architecture Each OMM manages NE including sub-devices. As Figure 11 illustrates, the standard configuration consists of two OMM servers, two maintenance consoles and one alarm box.

As Figure 11 illustrates, if NE does not offer 1x EV-DO function, addition of session server to the architecture becomes necessary.

POMC/LOMC Architecture As Figure 12 illustrates, POMS architecture is similar to LOMC. The difference lies in POMC interconnection with LOMC and OMM. LOMC enables only centralized management of multiple OMMs. The hardware comprises server, work station and communication equipment. The server implements disk array configuration. The communication equipment comprises router and interface converter to communicate with lower level OMM. OMM implements the corresponding communication equipment configuration.

Reliability Design This chapter explains: ZXC10 BSSB system hardware and software design reliability.

System Design Reliability Electromagnetic compatibility ZXC10 BSSB complies with international Electromagnetic compatibility (EMC) standards associated with communication products.

System maintenance design Simple internal cable routing inside the cabinet enables easy cable removal when replacing faulty boards. Such situations require removing only cables related to a particular faulty board. When replacing boards, directly unplug, plug and replace boards. Indicator flash helps identify normal system operational status.

Monitoring and handling system faults The system automatically detects, diagnoses software and hardware faults, reports and generates corresponding alarms. It records and outputs faults, and simultaneously collects environment information, and helps identify problems and reports them in real time.


39


Hardware Design Reliability Simplified design A simple system design and reasonable function layout reduces the number of board types. The board design involves minimum complications while ensuring full functionality.

Component design Stringent quality controls on components ensure component reliability. Use of universal components belonging to a standard manufacturer ensures ease of component replacement and reliable functioning. According to design requirements, component de-rating further improves component reliability. For power components that are part of power converter and AC/DC power module, load power under normal operations is less than 70% of rated output power. For used IC components, serving frequency rate is less than the maximum permissible frequency. Components like FPGA, EPLD, SDRAM and RS-422 drive require de-rating. To reduce instant current impact, all ICs have a decoupling capacitor at the input power end. The capacitor dielectric strength is usually greater than 30% of working voltage.

Redundancy design Some boards follow 1+1 hot backup mode and N+1 hot backup. Power section follows mutual backup.

Thermal Design BSC and BTS follow forced air cooling to keep working temperature within reasonable range in the rack. Larger power consumption by high power amplifier necessitates use of exclusive air ducts.

Protection Design Working ground of internal grounding cable is separate from protection. Internal grounding with external ground connection requires uniform grounding of rack exterior while maintaining overall grounding resistance less than or equal to 5 ohm.

Interference Resistance Design Rack power inlet port configuration with power cable filter enables resistance to interference and radiation.

Design Test For all board designs, tests under normal operations ensure reliability. Lower level board configuration tests with corresponding I2C and RS-485 interfaces ensure proper board design.

Software Design Reliability Software development conforms to Capability Maturity Model (CMM) specifications. Stringent technical analysis and reviews improve performance.

Demand Analysis Stage Demand information collection, careful analysis and review of demand description ensures description completeness and accuracy.

When the system informs users of operation completion in a closed server environment, all configuration data from the last operational state remain in the next booting. OMC detects the discrepancy arising out of foreground equipment. It completes data synchronization in manual or automatic mode. In normal operational status, different data and states in the client, server and equipment make detection and recovery possible. Input data is subject to consistency examination. In addition, data protection function is available. Login and operation security protection is available. Regular operational data backup is available in addition to key system software configuration files. These measures ensure data reconstruction of the latest backup point after complete system collapse.

Test Stage Tests are an essential instrument to improve software quality. Independent development stages of software modules involve application of strict emulated verification in the unit test. The integration test plan follows module development completion. System test begins on successful integration test completion. System test comprises system performance test, service function test, interface protocol consistency test, system capacity test and system large load test. On attaining system test maturity, access network test starts. On-site trial test follows the successful completion of access network test. Application of test data improves design.

Maintenance Stage The software patch function upgrades the designated functional modules on-line instead of interfering with normal software operations.

Level 1 (MTP1) MTP1 defines the physical, electrical function features and link access methods of data link signaling.

Level 2 (MTP2) MTP2 defines the function and program of transferring signaling messages over data link. Level 2, along with MTP1 ensures that transfer of signaling messages takes place reliably over two signaling points.

Level 3 (MTP3) MTP3 helps transmit messages to the proper signaling link or UP. In the face of barrier or congestion, this level can complete the recombination of network signaling to ensure reliable transfer of signaling messages.

Level 4 Level 4 is an application layer that consists of a variety of UPs. In the example, A1 level signaling occurs prior to SCCP level expansion. In order to expand SS7 transport function and maintaining consistency between SS7 and OSI reference model, addition of MTP3 to SCCP and TC modules suit applications of SS7 to IN, NMS, Public Land Mobile Network and N-ISDN supplementary services. Signaling transmission model formed by MTP and SCCP is similar to the bottom three OSI layers. MTP1 performs the OSI physical layer function and MTP2 performs the OSI data link layer function. MTP3 and SCCP perform the OSI network layer function together. Compared with IOS2.1 version, IOS4.X standard defines more A1 signaling interface contents: Support for packet data call. Support for preferred terrestrial circuit.

E1/T1

Pulse Code Modulation (PCM) is a voice code modulation where analog voice conversion takes place at 64 Kb/s or 56 Kb/s using analog/data conversion and PCM code. In China and Europe the code rule where PCM transmits each received voice channel at 64 Kb/s over E1 trunk lines. In the American μ code rule PCM transmits received voice channels at 56 Kb/s over T1 trunk lines.

A1p Interface 2G BSS uses A1 and A2 interfaces to connect with 3G CS core network. ADM transmission uses both A1 and A2 interfaces. 3G BSS uses A1p and A2p interfaces to connect with 3G CS core network. IP transmission uses both A1p and A2p interfaces. A1p interface functions as the signaling interface connecting MSC and 3G BSC. Figure 19 illustrates the A1p protocol stack structure.

SCTP SCTP provides a reliable message transport in IP networks. An association is a SCTP connection between two endpoints. A logical aggregation of streams constitutes one SCTP association. A stream is a


47


unidirectional logical channel between two endpoints. Bi-directional communication requires two streams, one for each direction. SCTP specifies the user stream attaching each user message originating from the user application. A stream identifier exists for each stream within an association. Each SCTP stream is an independent flow of user messages flowing from one node to another. This stream independent characteristic provides a mechanism to avoid and/or manage blocking between streams.

SUA SUA supports signaling messages between the MSCe and BS. BSAP uses one SUA signaling connection for the transfer of layer 3 (A1p) messages per MS. SUA uses both connectionless (Class 0) and connection-oriented (Class 2) procedures to support BSAP. The procedures in this specification identify whether connection-oriented or connectionless procedures can use each layer 3 (A1p) procedure. The use of SUA is within the standards defined in the equivalent subset of SCCP functions.

A2p Interface The A2p interface functions as the voice bearer service interface connecting MGW and 3G BSC. Figure 20 illustrates the A2p protocol stack structure.

The protocol stack options for transport of user traffic over A2p available to operators and manufacturers include EVRC or SMV, PCM (G.711), 13K, DTMF.

A3 Interface The mobile station uses A3 interface for soft handoff (Base Station Controller [BSC] interconnection) of signaling and service information between BSSs in the service channel state.

A3 interfaces are of two types: A3 signaling interface and A3 service interface. Figure 21 illustrates the protocol stack structure of A3 signaling interface.

A3 Signal TCP IP AAL5 ATM Physical Layer

Physical Layer The ZXC10 BSSB equipment uses E1/T1 trunk cables or Ethernet.

ATM Asynchronous Transfer Mode (ATM) is a data transfer mode that combines packet transfer with circuit transfer features. This mode breaks down the digital information into data blocks of 48 bits each. Each data block adds header data (cell header in ATM terminology) at the beginning of data blocks. They form the cell with 53 bits. This feature is similar to packet transfer. Cells from different message sources queue in the receiving buffer. According to the “first in and first out” principle, they are output to the transmission line. This feature is similar to packet transfer. The difference lies in the fact that ATM cell has fixed length and that data packet length is variable. Because of ATM fixed cell length, time-division multiplexing mode employs use of similar circuit transfer. The ATM cell placed in circuit transmission evolves to ATM transmission mode. Different from circuit transfer mode, ATM cells do not have fixed time slot numbers.

AAL5 ATM Adaptation Layer (ATM Adaptation Layer) provides adaptation function to various ATM transmission services, and makes the service suitable for ATM transfer. AAL uses five different protocols: AAL1, AAL2, AAL3, AAL4 and AAL5. AAL5 uses A3 interface; AAL2 uses A7 interface. AAL5 transmits larger data packets; AAL2 enables voice service transmission at variable transfer rates.

IP IP is the TCP/IP network layer protocol. IP packets contain destination and transmitting end IP addresses.


49


TCP TCP is the TCP/IP transport layer protocol that provides connectionoriented and flow control services to packet data ensuring reliable packet transmission. TCP packets contain the destination application TCP port number and transmitting end application TCP port number.

V5 Interface V5 physical layer consists of 2.048 Mb/s links. V5.1 consists of one 2.048 Mb/s links whereas V5.2 consists of 1~16 2.048 Mb/s links. One link consists of 64 Kb/s time slots that include B and C channels. B channel (Bearer channel) carries B channel data and ISDN BRA or PRA signaling information or PSTN call information. C channel carries D channel data and ISDN BRA and PRA signaling information or PSTN signaling information.


59


V5 data link layer transmission capability for layer 3 data transfer, messaging, ISDN-D channel signaling includes LAPV5-EF (Encapsulation Function sub-layer), LAPV5-DL (Data link sub-layer), AN frame relay sublayer, mapping function sub-layer. LAPV5-EF provides common encapsulation and disassembly of LAPV5DL and LAPD frames. LAPV5-DL transfers layer 3 messages between LE and subscribers by means of 5 protocols. AN frame relay sub-layer provides frame multiplexing and demultiplexing of ISDN user ports in-sync with LAPV5-EF sub-layer. Encapsulation takes place from AN to LE, while de-encapsulation takes place from AN to user. Two communication protocols that V5.1 interface uses are PSTN protocol module and control protocol module. Whereas V5.2 interface uses PSTN protocol module, control protocol module, link control protocol module, BCC protocol module, protection protocol module. Figure 34 illustrates the V5 interface protocol stack structure.

FIGURE 34 - V5 INTERFACE PROTOCOL STACK STRUCTURE

PSTN protocol provides protocols relating to specific calls. It transmits analog line status information such as off-hook and online over V5 interface. Control protocol consists of common control port and user control port. Common control port provides V5 interface operations such as interface start, interface provisioning, block/unblock specific user port. User port control involves controlling all user port types such as ISDN port, PSTN port etc. Blocking/unblocking, activation/de-activation of user ports is possible. Link control protocol provides link status management, confirming link availability at both ends, and blocking/unblocking links.

60



BCC protocol provides a channel for LE to request AN establish and release connections between designated AN user port and V5.2 interface. In short it controls allocation and release of B channel.

Um Interface ZXC10 BSS supports 1x Um interface and 1x EV-DO Um interface at the same time. The BCMCS technology makes the most of the available bandwidth and enables broadcast service transmission similar to TV programs through mobile telecommunications network.

1x Um Interface The Base Station Subsystem (BSS) Um interface complies with IS-2000 protocol standards. The Um interface layers consist of physical layer, MAC and LAC sublayer, and higher layers. Figure 35 illustrates the protocol reference model.

FIGURE 35 - REFERENCE MODEL OF STANDARD 1X UM INTERFACE PROTOCOLS

The following section describes the structure and functional features of MAC and LAC sublayers.

Physical Layer The Physical layer provides the requisite physical channels for establishing radio communication links with the upper Um interface layers.


61


MAC Sublayer According to IS-2000 protocol architecture, the MAC sublayer mainly includes multiplexing and demultiplexing sublayers, and Radio Link Protocol (RLP) implementation: Common Channel Multiplexing Sublayer: Completes multiplexing and demultiplexing of common signaling channels and completes TS-based transmission and reception according to message length and transmitted TS. Dedicated Channel Multiplexing Sublayer: Completes multiplexing & demultiplexing of the dedicated channel (traffic channel). It multiplexes the signaling fragments from SAR sublayer of LAC layer, voice data from Vocoder, and circuit data or packet data from RLP into a physical channel frame. It reverse demultiplexes a specific physical channel frame into signaling fragments, voice data, circuit data and packet data, and transmits them to the corresponding upper-layer protocol stacks for processing. RLP implementation: Different protocol stacks provide different upperlayer protocol stack requirements, to achieve reliable or real-time data transmission mechanism between the base station and MS.

LAC Sublayer According to IS-2000 protocol architecture, LAC sublayer functionally completes acknowledged re-transmission mechanism, segmentation and reassembly mechanisms of protocol signaling. Figure 35 illustrates the functions and structure of the forward channel LAC sublayer. F-SYNC channel achieves the functions of utility sublayer and SAR sublayer. F-BCCH channel achieves the functions of utility sublayer and SAR sublayer. For other forward common control channels, it achieves Automatic Repeat Request (ARQ) sublayer functions, addressing sublayer, utility sublayer and SAR sublayer. For forward dedicated signaling channels, it achieves (F-DCCH and F-FCH), ARQ sublayer function, utility sublayer and SAR sublayer. Figure 35 illustrates the reverse channel LAC sublayer functional structure. For reverse common control channel, the LAC sublayer achieves authentication sublayer functions, ARQ sublayer, addressing sublayer, utility sublayer and SAR sublayer. The authentication sublayer presents the LAC PDU authentication field on the reverse common signaling channel to initiate MS authentication procedure. The ARQ sublayer achieves signal delivery acknowledgement mechanisms between the base station and MS. It assures reliable signal transmission and reception and implements duplicate signal detection.

62



The utility sublayer presents the fields regarding message type and radio environment report in the forward and reverse LAC PDUs. The upper layers can identify the message and decide on access handoff initiation. The utility sublayer also maintains padding BIT and message length in PDUs. The SAR sublayer achieves segmentation and reassembly functions. In the forward direction, it segments a message to multiplex the message into one physical channel frame. In the reverse direction, it reassembles multiple message segments into a complete message sequence.

Application Layer The application layer provides multiple applications like Default Signal. Application for transmitting air interface message, and Default Packet & Circuit Applications for transmitting data. In addition, the layer provides a platform for Mobility Management (MM), Radio Resource Management (RRM), and Connection Management (CM) for managing user applications.

1x EV-DO Um Interface 1x EV-DO air interface complies with IS-856 protocol standards. It consists of seven layers: application layer, stream layer, session layer, connection layer, security layer, MAC layer and physical layer. Each layer defines one or more protocols to implement functions. Figure 36 illustrates the entire protocol reference model.

The following describes the functional features and structure of application layer, stream layer, session layer, connection layer, security layer, MAC layer and physical layer.

Application Layer The application layer provides multiple applications like Default Signal Application for transmitting air interface message and Default Packet Application for transmitting data. The Default Signal Application defines two protocols: Signaling Network Protocol (SNP) and Signaling Link Protocol (SLP). The protocols on all layers exchange messages through SNP. The SLP achieves message segmentation and reassembly, best-effort delivery, reliable delivery, and duplicate packet detection. Default Packet Application offers a byte stream for transmitting packet data between the terminal and network. It consists of three protocols: Flow Control Protocol provides flow control function for data stream. Radio Link Protocol provides byte stream re-transmission, packet check and so on. It also provides a relatively reliable data link. Location Update Protocol provides location update program and corresponding messages for mobile management of packet application.

64



Stream Layer The stream layer provides a multiplex/de-multiplex mechanism for upper layer applications. 1x EV-DO has a provision for at most four streams. Stream 0 is for signaling and others for transmitting subscriber data.

Session Layer The session layer includes a series of protocols for negotiation between the terminal and network. In the 1x EV-DO system, a session refers to a state jointly maintained between AT and AN. It includes address UATI allocated to the terminal, the protocol set determined by the terminal and for air interface communication network, protocol configurations in the protocol set, and current terminal location. The session layer defines three protocols: Session Management Protocol manages activation of other protocols in this layer to ensure session validity, and to manage session shutdown. Address Management Protocol manages the terminal address (UATI) allocation. Session Configuration Protocol provides the session flow negotiation. In 1x EV-DO, SCP negotiates the protocol for terminal-network communication and setting of protocol parameters.

Connection Layer The connection layer controls the air link state. In 1x EV-DO systems, an open connection between AN and AT indicates that AT involves RPC, RTC and FTC (FTC is the time division shared by all subscribers with open connections in the sector) assignment. The connection layer defines multiple protocols in the connection layer. Figure 37 illustrates the mutual relationships between protocols.

Overhead Messages Protocol

Among protocols, Packet Consolidation Protocol functionally encapsulates/de-encapsulates the transmitted/received data packets. Others are control protocols and described in the following section: Air Link Management Protocol is the general control point responsible for connection state jump and control of activation operation of other protocols. Initialization State Protocol defines the operation networks receive section. Idle State Protocol defines the operation after the terminal obtains network address but without establishing connection. Connected State Protocol defines the operation after opening the terminal. Route Update Protocol is responsible for maintaining radio link between the terminal and network, and tracing terminal location. Overhead Message Protocol is responsible for controlling the sending of broadcast messages in the channel.

Security Layer The security layer offers the following functions: Key exchange: Provides a procedure for the terminal and network to exchange security keys for authentication and encryption. Authentication: Provides a set of programs for the terminal and the network to authenticate air traffic. Encryption: Provides a set of programs for the terminal and the network to encrypt air traffic.

66



The security layer includes four protocols: Key Exchange Protocol, Authentication Protocol, Encryption Protocol, and Security Protocol. The first three define the above three functions respectively, and the last one provides common variables for Authentication Protocol and Encryption Protocol.

MAC Layer The MAC layer defines the rules for managing the control channel, access channel, and forward/reverse traffic channel. It includes four protocols with the following functions: Control Channel MAC Protocol: Constructs control channel MAC layer packet from one or multiple security layer packets. It controls the rules for packet scheduling & transmission in the control channel and terminal capture of control channel and reception of control channel packets. Access Channel MAC Protocol: The terminal sends timing and power features in the access channel. Forward Traffic Channel Protocol: Contains the rules regarding FTC rate control through DRC and supports fixed rate and variable rate FTC. Reverse Traffic Channel Protocol: Determines how the terminal assists the network in capturing RTC and how the terminal and network selects RTC rate.

Physical Layer The physical layer provides multiple features such as structure, frequency, power output, modulation/demodulation, and coding/decoding of forward/reverse channels.

BCMCS Um Interface The BCMCS air interface is critical for HRPD to deliver broadcast and multicast services. Figure 38 illustrates the BCMCS air interface protocol stack structure.

Link Layer The link layer supports multiple protocols: High level Data Link Control (HDLC), Point-to-Point Protocol (PPP), PPPmux and PPPmultilink. HDLC: Is a bit-oriented data link layer protocol. The bit-oriented feature involves taking a bit (not character) as a basic transmission unit and controlling information. The data frame format is similar to control frame format, and has good transmission transparency and high efficiency. PPP is a link layer protocol with a simple link design that transmits data packets between peer units. PPPmux completes transmission of multiple PPP encapsulation packets (or subframe) by single PPP frame and reduces PPP cost of each packet. It applies to voice and data transmission over low speed links. PPPmultilink is a link type protocol applicable to point-to-point links when a link exceeds certain flow or during initiation of other links.

IP IP is a TCP/IP network layer protocol. IP packets contain destination IP address and transmitting end IP address.

TCP/UDP/cUDP TCP is the TCP/IP transport layer protocol. TCP provides connectionoriented and flow control services to packet data ensuring reliable packet transmission. TCP packets contain destination application TCP port number and transmitting end application TCP port number. UDP is a connectionless protocol. cUDP is a compressed user Datagram protocol.

Abis Traffic/Abis Signal Application layer contains two parts: control signaling part and service signaling part. The signaling part carries out converse control channel signaling of Um interface. The service part completes service management and service transmission.
