Problems solved by technology

[0019] The disadvantage of this solution is: because the current load conditions of the central cell and inter-frequency neighboring cells are not taken into account, and options such as "reselection start threshold" and "reselection bias" are not configured in combination with the current load conditions and the reselection results Reselection parameters, so that which cell the user terminal camps on is only related to the signal quality of the cell, so that it cannot automatically select a cell with a lighter load
[0030] The disadvantage of the above scheme 2 is that only the current load conditions of the central cell and inter-frequency adjacent cells are considered, but the selection and reselection parameters such as "reselection start threshold" and "reselection bias" are not automatically adjusted according to the selection and reselection results
Therefore, it is impossible to optimize the configuration methods of reselection parameters such as "reselection start threshold" and "reselection bias".

Embodiment Construction

[0044] The method for optimizing the network of the present invention will be described below with reference to the accompanying drawings.

[0045] figure 1 It is a flowchart of a method for optimizing a network according to an embodiment of the present invention.

[0046] Such as figure 1 As shown, the network optimization method of the present invention comprises the following steps:

[0047]Step 1: Within a specified range and within a specified time (statistical time), the radio network controller measures "the number of times selection and reselection parameters are updated due to changes in cell load". The measured parameters include: when the load of the cell becomes lower than, higher than or equal to the predetermined load, the number of times to update the "reselection start threshold"; When loaded, the number of times to update the "reselection bias".

[0048] Step 2: Optimize the network configuration according to the measurement results.

[0049] In the measu...

Abstract

This invention provides a method for optimizing the performance of network including: measuring the times of re-refreshing the re-selected parameters due to the change of load in a local area in the appointed sphere and time and optimizing the network configuration based on the measurement result, so that users can stay at the local areas with rather light load to avoid congestion resulted in great number of users concentrating on one or several areas.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for optimizing network performance. Background technique [0002] In a wireless mobile communication system, after the user terminal is powered on, it will start a cell selection and reselection process, so that the user can always camp on a suitable cell (Suitable Cell). The initial cell selection process is called "cell selection", and the subsequent process for the user terminal to select a suitable cell with better radio link quality is called "cell reselection". [0003] After a user terminal camps in a certain cell, once it initiates a call or requests a service, it will occupy the radio resources of the cell. Therefore, under the condition that the link quality requirement is met, the user terminal should camp on a cell with a relatively light load as much as possible. [0004] Taking the inter-frequency cell reselection under the non-hierarchical cell stru...
