Problems solved by technology

[0006] When faced with the problem of how to realize long-term expansion planning during the network operation phase, the pre-planning method in Part 1, although phased planning has been carried out in the pre-planning phase, the business forecast it relies on may not match the actual network development ; At the same time, the input information of the capacity estimation method is limited, and the calculation formula of uplink interference and downlink power is generally used to evaluate the performance of the network. The input information includes service rate, signal-to-noise ratio, adjacent cell interference factor, downlink transmit power, and orthogona

[0043] In the first embodiment of the present invention, a method for WCDMA network expansion planning, such as figure 1 shown, including the following specific steps:

[0044] Step S101, classify the cells according to the relevant parameters of the cells. The relevant parameters of the cells include: area type (such as: dense urban area, general urban area, suburb, rural area, road, etc.), cell transmission power, indoor and outdoor stations, and similarities and differences between HSDPA and R99 frequency strategy. Specifically, the cells are classified according to the different values ​​of the above four cell-related parameters, and as long as one of the parameters is different, it is a new type of cell.

[0045] Step S102, collect the current business volume and resource consumption of the same type of cells in the live network, and establish the relationship between resource consumption and business volume based on this, and so on, and establish resource consumption fo...

[0057] In the second embodiment of the present invention, a device for WCDMA network expansion planning, such as figure 2 shown, including the following components:

[0058] The cell type classification module 10 is used to classify cells according to cell-related parameters. And the same frequency strategy between HSDPA and R99.

[0059] Association relationship establishing module 20, used to collect the current business volume and resource consumption of the same type of cells in the live network, and establish the relationship between resource consumption and business volume accordingly, and so on, for different types of cells Respectively establish an association relationship between resource consumption and business volume.

[0060] Specifically, the relationship establishment module 20 uses the collected current traffic volume of each cell of the same type as an independent variable, and takes the collected current network resource consumption as a dependent variable...

Abstract

The invention discloses expansion planning method and device for a WCDMA (wideband code division multiple access) network. The method includes: collecting current service volume of the same class of cells in a current network and resource consumption of the current network and correspondingly establishing association relationship between the resource consumption and the service volume; calculating expected resource consumption of the same class of cells corresponding to expected service volume according to the association relationship; comparing the expected resource consumption of the same class of cells to a set resource consumption threshold so as to determine whether to expand the current network or not. Compared with the prior art, the method and device determine the association relationship between the resource consumption and the service volume by the current network, so that coincidence of the planning method with the current network is guaranteed. Inputting of network state parameters required by preplanning is not needed, so that labor of network expansion planning is reduced. The expansion planning method is simple and effective in process, simple to operate, easy to implement and widely applicable.

Description

technical field [0001] The invention relates to the technical field of wireless network communication planning, in particular to a method and device for WCDMA (Wideband Code Division Multiple Access, wideband code division multiple access) network expansion planning. Background technique [0002] For WCDMA commercial networks, as the number of users and business volume continue to increase, it is necessary to determine the way of expansion and the equipment to be added according to the expected capacity, growth demand, and consumption of existing network resources. The resources to be monitored for capacity expansion include: power, codeword, uplink interference, CE (Channel Element, channel processing unit) and transmission, etc. The corresponding expansion means include increasing power amplifier, carrier frequency, CE and transmission resources, etc. [0003] The current wireless network planning and network optimization only involves the following: [0004] Contents of ...
