Embodiment 1

[0043] See figure 1 As shown, the method for reducing the call drop rate in the implementation of the ANR process provided by this embodiment includes:

[0044] Step 101: Receive a report sent by the terminal; the report can be a serving cell measurement report sent by the terminal; it can also be other reports, as long as relevant information for identifying the serving cell can be obtained according to the report, such as the physical cell identifier PCI; In the following process, only the measurement report is taken as an example for illustration;

[0045] Step 102: discovering an unknown serving cell according to the report sent by the terminal, specifically according to the PCI (Physical Cell Identity) of the serving cell to distinguish whether it is an unknown serving cell;

[0046] Step 103: Select a terminal whose signal strength is within a preset signal strength range from the online terminals in the unknown serving cell as the target terminal to execute the ANR pro...

Embodiment 2

[0064] This embodiment also provides a device for reducing the call drop rate during the ANR process, which can be set in a base station or other control entity, and can also exist as a separate entity. Please refer to figure 2 shown, which includes:

[0065] The receiving module 1 is used to receive the report reported by the terminal; the report can be the serving cell measurement report sent by the terminal; it can also be other reports, as long as relevant information for identifying the serving cell can be obtained according to the report, such as the physical cell identity PCI That’s it; in the following process, only the measurement report is taken as an example for illustration;

[0066] The discovery module 2 is used to discover an unknown serving cell according to the report sent by the terminal; it can judge whether the serving cell is an unknown cell according to the PCI contained in the measurement report sent by the terminal, that is, whether it is an unconfigur...

Embodiment 3

[0083] In this embodiment, several specific application examples are taken as examples to further illustrate the present invention.

Abstract

The invention discloses a method, a device and a base station for reducing call drop rate in a process of executing an ANR. The method for reducing the call drop rate in the process of executing ANR comprises steps of discovering an unknown service cell according to a report transmitted from a terminal and choosing a terminal with signal strength within a preset signal strength range from online terminals in the unknown service cell. As a result, the method, the device and the base station can guarantee that quality of a terminal signal for executing the ANR flow satisfies a requirement for executing the ANR flow, improves terminal online robustness in the process of executing the related ANR related operation, can dramatically reduce an occurrence rate that an RLF scene is produced because UE signal quality is poor during the process of executing the ANR, and can reduce the call drop rate. Furthermore, a fact that a terminal with good signal quality is chosen to execute the ANR related operation can reduce error probabilities of uplink demodulation and downlink demodulation due to poor signal quality, guarantees normal completion of the flow having timeliness, further reduces the call drop rate and improves the user experience.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and base station for reducing the call drop rate in the process of implementing ANR (Automatic NeighborRelation, automatic neighbor relationship). Background technique [0002] With the deepening of LTE (Long Term Evolution, Long Term Evolution) commercial use, there are more or less scenarios in the LTE network where the relationship between adjacent cells is not configured, missing or mismatched, and LTE network optimization is becoming more important. In order to make the network as optimal as possible Excellent, but without increasing the cost of manpower operation and maintenance, the ANR function is launched in the field of LTE technology, and it will be frequently deployed and applied with the deepening of LTE commercial use. The principle of ANR function is: through UE (User Equipment, user terminal) behavior collection The network information is reporte...
