NodeB LMT User Guide Chapter 12 Managing NodeB Clock Chapter 12 Managing NodeB Clock 12.1 About This Chapter This chapter presents knowledge of the NodeB clock and means of maintaining the clock. 12.2 Overview of NodeB Clock 12.2.1 Principle of Clock The NodeB clock module is mounted on the NMPT to provide timing signals for the NodeB. Under normal conditions, the NodeB clock works in the phase-lock mode. It keeps precision by tracing the assigned high-precision reference clock source. There are three reference clock sources for the NodeB: z Iub interface clock z GPS clock z External clock Only one clock synchronization mode is available at the same time. When the NodeB clock synchronization source is faulty, the NodeB works in free-run mode. This enables the NodeB clock to run for another 90 days. 12.2.2 Center Frequency DA Value The center frequency value is also called center DA value. When the NodeB is in normal operation, the master clock frequency is about 10 MHz, which is output from the Oven Controlled Crystal Oscillator (OCXO) in the NMPT. Fine tuning on the main clock frequency can be realized by adjusting voltage on the OCXO. The quantized value of the voltage corresponding to the exact 10 MHz is referred to as the center frequency DA. 12.2.3 Current Frequency DA Value The current frequency DA value is also referred to as current DA value. z When the NodeB clock works in the free-run mode, the current DA value is the same as the center DA value. Huawei Technologies Proprietary 12-1
NodeB LMT User Guide Chapter 12 Managing NodeB Clock z When the NodeB is using a reference clock source, the current DA value of the NodeB clock synchronizes with the frequency of the clock source. Namely, the current DA value is adjusted according to the frequency difference of the clock source during the software phase-locking. z If the external clock source stays locked for seven consecutive days, it shows that the clock source is stable. In that case, the clock module shall overwrite the center DA value with the current DA value. Upon resetting the NMPT or the NodeB, the current DA value shall be overwritten with the center DA value. 12.2.4 Initial DA Value The initial DA value is the center frequency DA value preset in the NMPT before its delivery. When the NodeB is started for the first time, this value is written into the configuration file as the center frequency DA value. Therefore, the initial DA value can be regarded as the center frequency DA value preset before the NodeB delivery. 12.3 Querying Clock Status 12.3.1 Overview of Querying Clock Status You can query the following clock status: z Current clock status z History clock status 12.3.2 Introduction to Clock Status I. Current Clock Status The current clock status may include: z Configured clock source z Configured clock source status z Configured work mode z Current work mode z Clock status z Center DA z Current DA z Original DA II. History Clock Status The history clock status may include: z Time Huawei Technologies Proprietary 12-2

For the DBS3800, you can query the current clock status only when the MBBU or HBBI works well.  Note: You can query the current NodeB clock status by the MML command of DSP CURRCLK. 12.3.4 Querying History Clock Record I. Introduction You may query the history clock record to know the change in current frequency DA value. The history clock record stores details about changes of the clock DA value. II. Prerequisite None. Huawei Technologies Proprietary 12-4
NodeB LMT User Guide Chapter 12 Managing NodeB Clock III. Procedure You can query the history clock status by the MML command of LST CLKRECORD. 12.4 Managing NodeB Clock Source 12.4.1 Overview Managing the clock source refers to z Setting NodeB clock work mode z Setting NodeB clock source z Testing NodeB clock source quality 12.4.2 Introduction to NodeB Clock Source The NodeB needs to lock to an external clock to calibrate its master clock frequency. Then the external clock is the clock source. There are three clock sources available for the NodeB, including z Iub interface clock source: It is the default setting by the system. The NodeB extracts clock signals from the Iub interface between NodeB and RNC as its reference clock source. z External clock source: The NodeB locks to a 2.048 MHz external clock as its reference clock source. The clock source can be a BITS clock or a clock at the synchronous interface of the SDH equipment. z GPS clock source: The NodeB uses the clock signals generated from the GPS receive card built in the NMPT as its reference clock source. 12.4.3 Setting NodeB Clock Work Mode I. Introduction Caution: z This operation causes faults easily. z Do Not execute this command without Huawei technical support. The NodeB clock work modes include lock mode and free mode. z The clock work mode can be set to "lock" only when there is an external reference clock source. Huawei Technologies Proprietary 12-5
NodeB LMT User Guide Chapter 12 Managing NodeB Clock z When the clock work mode is "free", the NodeB clock works in the free-run mode and the clock source does not work. z If the clock source is faulty and needs calibrating, set the work mode into the free mode and then calibrate the frequency value to the center frequency DA value. This action is usually performed together with actions in subsection 12.5.4 "Setting NodeB Clock Current Frequency ". z You need to set the NodeB clock work mode before setting the current frequency value. II. Prerequisite Be sure to set the clock work mode one minute after the NodeB initialization. III. Procedure You can modify the NodeB clock work mode by the MML of MOD CLKMODE only. 12.4.4 Setting NodeB Clock Source I. Introduction The NodeB needs to lock to an external clock to calibrate its master clock frequency. Then the external clock is the clock source. You must select a proper clock source for the NodeB before it starts running. The system automatically locks to the clock source after setting the clock source. There is no need for other manual settings. II. Prerequisites Be cautious about the following items before you set the clock source: z To use the Iub interface clock or GPS clock, make sure the clock source is available. z To use the GPS clock, make sure there is a GPS card on the NMPT. If there is a GPS card, execute the MML command of DSP GPS to check whether the GPS clock source is available. You can set the clock source only when the GPS clock source is available. z To use the Iub interface clock, set the Iub interface and the Iub interface board from which the NodeB extracts clock signals. And then check the settings by the MML commands of DSP IUBCLK, ADD IUBCLK and RMV IUBCLK. III. Procedure You can set the reference clock source by the MML command of MOD CLKSRC.

NodeB LMT User Guide Chapter 13 Managing NodeB Cells Chapter 13 Managing NodeB Cells 13.1 About This Chapter This chapter describes knowledge of the NodeB cell and means of managing the cell. 13.2 Overview 13.2.1 Local Cell and Logical Cell A local cell is an integration of physical resources (hardware and software resources) of a cell in NodeB. The local cell relates to the implementation of a device. Local cells are configured on and managed by the NodeB. A logical cell is a standard logical model of cell radio resources controlled by an RNC. It is independent from the implementation of the NodeB local cell. Logical cells are configured on and managed by the RNC. One logical cell corresponds to one local cell. 13.2.2 Cell Radius and Handover Radius Definitions of cell radius and handover radius are as follows: z Cell Radius: refers to the access radius of a cell, that is, radius of the coverage area. A UE in the coverage area of a cell can access the cell in theory. z Handover Radius: refers to the radius where a UE is handed over from the source cell to the target cell. The inner handover radius is defined to avoid resources waste by preventing frequent handover of the UE between the margins of the two cells. The UE is handed over only when the UE oversteps the inner handover radius. Relations between the cell radius and the handover radius are as follows: z The cell radius refers to the cell outer handover radius. It is greater than the cell inner handover radius. The area between the two radiuses is the handover area of the cell. z There is overlap between the access radiuses of two cells. This prevents call drops during the UE handover and ensures cell breathing. z There is no overlap between the inner handover radiuses of two cells. This ensures an area for handover. Huawei Technologies Proprietary 13-1
NodeB LMT User Guide Chapter 13 Managing NodeB Cells z There shall be an overlapped area between the inner handover radius of the source cell and the access radius of the target cell. Handover is not available in this area to reduce the handover area between two cells and avoid frequency handover. 13.2.3 Cell Status There are the following categories of cell status. I. Local Cell Status The local cell status consists of z Local Cell Unavailable-All Resource fault z Local Cell Unavailable-RF and Baseband Interface Resource fault z Local Cell Unavailable-RF and Baseband Resource fault z Local Cell Unavailable-RF Resource fault z Local Cell Unavailable-Baseband and Baseband Interface Resource fault z Local Cell Unavailable-Baseband Interface Resource fault z Local Cell Unavailable-Baseband Resource fault z Local Cell Available-NCP fault z Local Cell Available II. Cell Operation Status z Enable: The logical cell has been set up and ready for use. z Disable: The logical cell is not available. III. Cell Administration Status z Unblocked: The cell is not blocked. It works normally. You can block a cell in this state. z Shutting down: It is a transitional state before the RNC delivers a block response. The RNC delivers a block response only after a period or after the cell is idle. z Blocked: The cell has been blocked. You can unblock a cell in this state. 13.2.4 Blocking Cell There are three modes to block a cell: z High: blocking now z Normal: blocking by schedule z Low: blocking when resources are idle High is of the highest priority at the risk of partial service loss. Huawei Technologies Proprietary 13-2
NodeB LMT User Guide Chapter 13 Managing NodeB Cells If you select Normal, you may specify a period (1 to 3600 s). During this period, the cell no longer carries new services. After this period, the system blocks the cell even if it is carrying service. Low is of the lowest priority. In this mode, the system blocks the cell only when the cell does not carry service. 13.3 Querying Cell Configuration 13.3.1 Overview of Cell Configuration Query Querying cell configuration includes: z Querying cell configuration z Querying cell status 13.3.2 Introduction to Cell Configuration and Cell Status I. Cell Configuration The local cell configuration consists of z Local cell ID z Logical cell ID z Site ID z Sector ID z Local cell radius z Local cell inner handover radius The logical cell configuration consists of z Local cell ID z Logical cell ID z Uplink frequency (0.2 MHz) z Downlink frequency (0.2 MHz) z Cell max transmit power (0.1 dBm) z Cell primary scramble code z Cell transmit diversity indicator z Configuration of various channels II.
