Problems solved by technology
However, the accuracy of the industrial parameter data and the update timeliness after the change of the antenna feeder have all become unfavorable factors that affect the accuracy of the planned wireless communication neighbor cell; and the CSFB neighbor cell cannot fully meet the requirements of the eSRVCC neighbor cell. It is found that due to unreasonable or incomplete eSRVCC neighbor cell configuration, the voice quality after handover is poor or frequent handover, or even eSRVCC handover failure occurs

Embodiments of the present invention provide a method and device for configuring adjacent cells suitable for eSRVCC handover, by screening GSM network wireless communication cells that need to be eSRVCC handover within the current configuration range, and extracting from the multi-dimensional data suitable for eSRVCC handover The correlation factor of the eSRVCC handover of the GSM network wireless communication cell determines the correlation coefficient of the GSM network wireless communication cell suitable for eSRVCC handover; screens out the GSM network wireless communication cell suitable for eSRVCC handover according to the correlation coefficient, and performs eSRVCC handover The GSM network wireless communication cell performs adjacent cell configuration suitable for eSRVCC handover. The present invention accurately acquires neighboring cells with high eSRVCC switching adaptability and high switching success rate through multi-dimensional data, and improves the voice communication continuity and communication quality of the neighboring cells configured with eSRVCC switching.
Description
technical field [0001] The invention relates to the field of wireless service transmission, in particular to a method and device for configuring adjacent cells suitable for eSRVCC handover. Background technique [0002] eSRVCC (Enhanced Single Radio Voice Call Continuity, enhanced single radio voice call continuity) is an essential part of the current VOLTE (Voice Over Internet Protocol, voice transmission over the Internet) business. eSRVCC needs to configure the neighbor relationship between LTE network cells and GSM network cells, that is, 4G-2G neighbor cells can support services. Although the eSRVCC neighbor cell and the CSFB (Circuit Switched Fallback, circuit domain fallback) neighbor cell are set separately in the LTE system, the current eSRVCC neighbor cell generally inherits the existing neighbor cell between the LTE network cell and the GSM network cell. CSFB neighbors. [0003] Although both the eSRVCC neighbor cell and the CSFB neighbor cell are used for the U...
