1.1 Introduction to RND Radio Network Dimensioning (RND) is a software program used by network planners to plan the GSM and UMTS networks at the early construction stage. The RND covers the following functions:

z Network dimensioning by using different design types for different application scenarios z Independent calculation of each module, or the inheriting of calculation results among

modules z Network dimensioning in multiple cities and multiple networking scenarios

simultaneously z Importing/exporting parameters and calculation results, and importing the parameters

and calculation results into the RNP output template.

Currently the RND supports both GSM networks and UMTS networks, and applies to stand-alone systems only.

1.2 RND Application Scenarios The RND is used to estimate the network scale and required resources during the network planning stage. Based on different requirements on network specifications by different operators, the RND adopts different design types. Table 1-1 lists the mapping between network requirements and design types.

Table 1-1 RND application scenarios

Scenario Design Type

Coverage dimensioning at the early network construction stage when operators have no specific or low requirements on capacity

CE/Iub, and carrier dimensioning; the base station configurations are determined by the traffic model and network planning.

Channel elements, Iub, and carrier configuration

Network dimensioning based on U-Net coverage prediction function. The procedure is as follows: First calculate the cell radius based on the link budget function of the RND, forecast the coverage and adjust the site distance in the U-Net, and then estimate the network scale by inputting the adjusted cell radius in the dimensioning modules of the RND.

Scenario Design Type

Verifying the network dimensioning of the RND through U-Net simulation function. The procedure is as follows: Simulate the traffic parameters obtained from RND dimensioning through the Monte-Carlo simulation of the U-Net, then input the number of sites and carrier configurations in the RND, and configure the CE and the Iub interface.

1.3 RND System Structure The RND system consists of three layers: user interface layer, service layer, and data access layer. See Figure 1-1 for the detailed structure.

Figure 1-1 RND software structure

The following sections describe the user interface layer, service layer, and data access layer in detail.


User Manual


Issue 02 (2008-12-11)

1.3.1 User Interface Layer The user interface layer provides user interfaces and interfaces for various operations. The user interface layer reads data through the data access layer and invokes the service processing interfaces of the service layer. In this way a whole set of RND functions are realized. The user interface module in this layer presents the actual effects of various controls and provides interfaces for user operations.

1.3.2 Service Layer The service layer processes the RND services. This layer reads data through the data access layer and serves as a realization interface for user interface layer.

It consists of project management module and dimensioning control module. The functions of each module are as follows:

z The project management module manages RND projects. z The dimensioning control module controls concrete project dimensioning for

dimensioning algorithms. This module consists of multi-system dimensioning module and basic dimensioning function module. The multi-system dimensioning module involves GSM dimensioning module and

UMTS dimensioning module. The basic dimensioning function module provides a set of functions for multi-system

dimensioning algorithms.

1.3.3 Data Access Layer The data access layer provides the basis of accessing data for user interface layer and service layer. The data access module of this layer covers the following functions:

User Manual


Issue 02 (2008-12-11)

calculate the maximum coverage radius of TCHs or pilot channels by using the maximum path loss and the traffic model. This module covers two parts:

The continuous coverage services include the Circuit Switching (CS) services and Packet Switching (PS) services of R99, High Speed Downlink Packet Access (HSDPA) services, High Speed Uplink Packet Access (HSUPA) services, and Multimedia Broadcast Multicast Service (MBMS).

z Pilot link budget This part can calculate the coverage radius of the pilot channel, that is, the cell radius when the transmit power of the pilot channel is available.

The link budget module does not need to inherit the calculation results of other modules, and outputs the cell radius.

1.5.2 Cell Edge Throughput & Power Dimensioning This module can estimate the following items:

z HSDPA cell edge throughput The maximum data rate of the HSDPA for specific terminals at the cell edge is calculated on the basis of the cell radius.

This module inherits the number of subscribers per cell outputted by the capacity dimensioning module, or users enter the number of subscribers in this module. The module outputs the number of cells.

1.5.8 Number of Sites Dimensioning Based on Strategy The number of sites that can meet the capacity and coverage requirements, the actual number of subscribers per site, the actual number of subscribers per cell and the cell radius is calculated on the basis of the outputs of the preceding-discussed modules. These outputs involve the number of sites, cells, and maximum number of carriers supported by a single cell. The procedure is as follows:

1. Calculate the number of single-carrier cells by using the number of sites based on U-Net coverage prediction or entered by the user.

2. Calculate the number of multi-carrier cells based on the maximum number of carriers supported by a single cell.

3. Calculate the number of subscribers per site, the number of subscribers per cell, the number of sites, and the cell radius based on the number of multi-carrier cells, and the number of cells outputted by the number of cells dimensioning based on capacity module or entered by the user.

SPM for 900MHz The default value of SPM model is converted from the Cost231-Hata model. Therefore, the SPM model applies to the same scope as the Cost231-Hata model. The working band class is 900 MHz.

SPM for 2GHz The default value of SPM model is converted from the Cost231-Hata model.. Therefore, the SPM model applies to the same scope as the Cost231-Hata model. The working band class is 2GHz.

Asset for 900MHz

The Asset model is similar to the SPM model. The difference lies in the units: The Asset model adopts kilometer as its distance unit whereas the SPM uses meter.

Asset for 2GHz The Asset model is similar to the SPM model. The difference lies in the units: The Asset model adopts kilometer as its distance unit whereas the SPM uses meter.
