Problems solved by technology

When the carrier frequency is deleted, the carrier with the most interference in the network is not considered to be deleted. Therefore, it is impossible to use the opportunity of deleting the carrier to reduce the network co-channel interference as much as possible.
In addition, when the carrier frequency of the cell is deleted, whether there are users on the deleted carrier is not considered

Embodiment Construction

[0019] In order to make the purpose, technical means and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0020] During the initial planning of the network, the main carrier of each cell can be planned to have different frequencies, but it cannot be avoided that the secondary carrier of the cell has the same frequency as the main carrier or secondary carrier of the neighboring cell. Therefore, every time a cell adds a carrier, users accessing this carrier may cause co-frequency interference to neighboring cells, and if the added carrier has the same frequency as the main carrier of a neighboring cell, the interference to neighboring cells will be the greatest.

[0021] Based on this, the basic idea of ​​the present invention is: when the cell carrier changes, calculate the amount of interference that the added or reduced carrier may bring to neighboring cells, so as to s...

Abstract

The invention provides a dynamic carrier management method, which comprises the following steps of: for any cell managed by a radio network controller (RNC), correspondingly storing NPriNb, NSecNb and NPotentialNb for each carrier i of the cell by using the RNC, wherein NPriNb is the number of primary carriers at the same frequency with the carrier i in all neighbor cells of the cell, NSecNb is the number of established secondary carriers at the same frequency with the carrier i in all the neighbor cells of the cell, and NPotentialNb is the number of unestablished secondary carriers at the same frequency with the carrier i in all the neighbor cells of the cell; and in the addition and deletion of the carriers of the cell, calculating the interference of corresponding carriers in a network according to the NPriNb, the NSecNb and the NPotentialNb, selecting a carrier with the lowest interference for addition, and selecting a carrier with the highest interference for deletion, thereby minimizing the interference in the neighbor cells in the addition and deletion of the carriers.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a dynamic carrier management method. Background technique [0002] In the TD-SCDMA system, in order to increase the capacity of the network system, each cell can be configured with multiple carriers. When the cell is initially established, all configured carriers can be established, or only the main carrier can be established when the cell is initially established, and the secondary carrier of the cell can be gradually increased when the traffic volume of the cell reaches the threshold. This method of dynamically adding carriers according to traffic volume can save power resources for equipment, improve carrier utilization in the system, and reduce interference in mobile communication systems on the premise of ensuring network system capacity. [0003] After the radio network cell is established, the radio network controller (RNC) notifies the NodeB to add / delete the carrier of...
