Embodiment 1

[0101] An embodiment of the present invention provides a handover optimization method, the method includes: continuously acquiring at least one interference indication corresponding to M detection cycles, and determining whether the number of acquired interference indications is greater than or equal to a first preset threshold, and if If the number of interference indications in the serving cell is greater than or equal to the first preset threshold, the detection threshold of the serving cell is gradually increased to the target value, so that the UE under the serving cell can be transferred from the serving cell in time according to the adjusted detection threshold. The cell is handed over to the target cell. This solves the problem that when the serving cell is in a state of strong interference, the UE under the serving cell can be switched out in time to ensure the call quality of the UE and improve the communication stability of the serving cell.

Embodiment 2

[0122] Such as image 3 What is shown is another handover optimization method provided by the embodiment of the present invention, the method includes:

[0123] S301, counting the number of handover failures generated during the handover of UEs in the serving cell from the serving cell to the target cell;

[0124] S302. Determine the number of handover failures based on interference from the number of handover failures;

[0125] S303. Determine whether the determined number of interference-based handover failures is greater than or equal to a fourth preset threshold;

[0126] S304. If the number of interference-based handover failures is greater than or equal to the fourth preset threshold, obtain at least one received signal power value, and determine a maximum received signal power value among the at least one received signal power value as an adjustment value;

[0127] S305. Adjust the detection threshold of the serving cell to an adjusted value.

[0128] During the hand...

Embodiment 3

[0138] In the first embodiment, the handover optimization of the UE is realized based on the interference detection of the cell, and in the second embodiment, the handover optimization of the UE is realized based on the interference detection of the UE. Figure 4 Shown is a flow chart of a handover optimization method in an embodiment of the present invention, the method includes:

[0139] S401. Obtain a detection report reported by the UE;

[0140] Specifically, the UE determines the link communication quality with the serving cell based on a block error rate (English: Block Error Ratio, BLER for short) detection mechanism.

[0141] When the UE establishes a service bearer, the base station will configure the Total Cyclical Redundancy Check (Total Cyclical Redundancy Check, Total CRC) and the error cyclic redundancy check threshold Bad for each service of the UE through the measurement control message. CRC, pending trigger threshold Pending after trigger.

[0142] The UE wi...

Abstract

An embodiment of the present invention provides a handover optimization method and device, the method comprising: continuously acquiring at least one interference indication corresponding to M detection cycles, and determining whether the number of acquired interference indications is greater than or equal to a first preset threshold, If the number of interference indications obtained is greater than or equal to the first preset threshold, the detection threshold value of the serving cell is gradually increased to the target value, so that the UE under the serving cell can be detected in time according to the adjusted detection threshold value. Handover from serving cell to target cell. This solves the problem that when the serving cell is in a state of strong interference, the UE under the serving cell can be switched out in time, ensuring the call quality of the UE and improving the communication stability of the serving cell.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for handover optimization. Background technique [0002] In a wireless communication system, in order to cover the entire geographical area, according to the deployment of macro base stations, it is usually necessary to plan and design the area reasonably and meticulously, so that mobile terminals can be provided with better coverage in the entire geographical area. The macro network can cover most areas and provide services for user equipment (English: User Equipment, referred to as: UE) in the planned area through reasonable planning through artificial network planning. Even so, there will still be In areas that cannot be covered, it will not be possible to provide services for UEs or provide services that meet requirements in such areas, which seriously affects UE perception. [0003] In addition, since the area where UE services occur tod...
