A method and device for enabling esrvcc function

Abstract

The invention provides a method and device for starting an eSRVCC function, relates to the technical field of wireless communication, and can analyze the necessity of starting the eSRVCC function of acell according to mobile communication core network interface signaling data, thereby saving the function cost. The method comprises the following steps: obtaining user signaling record information,wherein the user signaling record information comprises a cell identifier, a user identifier, a network type and time; Determining the minimum interval time of the user terminal falling back to the second network type cell from the first network type cell according to the user signaling record information; If the minimum interval time after the user terminal falls back to a second network type cell from a first network type cell is smaller than a first preset threshold value, adding 1 to the counting times of the second network type cell; And if the counting frequency of the second network type cell exceeds a second preset threshold value within a preset time period, starting an eSRVCC function in the second network type cell.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a method and device for enabling an eSRVCC function. Background technique [0002] High definition call (Voice over LTE, VoLTE) is the final solution of the fourth generation communication technology (4th generation, 4G) network voice service. During the 4G network construction period, the 4G network failed to achieve full coverage, and weak coverage or even no coverage was inevitable. In the coverage area, in order to ensure the continuity of VoLTE voice calls, operators need to enable the enhanced single radio voice call continuity (Enhanced Single Radio Voice Call Continuity, eSRVCC) function. The user terminal can be switched from the 4G network to the third generation communication technology (3th generation, 3G) network or the second generation communication technology (2th generation, 2G) network. The eSRVCC function fee of the network is a la...

Problems solved by technology

[0003] Taking switching to a 3G network as an example, some operators currently have two methods for enabling the eSRVCC function in 3G cells: one is to enable the entire network without distinguishing between different cells. Obviously, this method is too expensive to invest

The other is to evaluate the 4G network coverage of the 3G cell coverage area based on the 4G measurement report (Measurement Report, MR) data. For 3G cells with poor 4G network coverage, enable it, and for 3G cells with good 4G network coverage, do not enable it. The method requires a large amount of MR data, and some operators have not collected data in some areas, so it is difficult to fully implement, and the coverage area of ​​3G cells cannot be accurately delineated (delineated by latitude and longitude) with the weak coverage area of ​​MR data, so the accuracy is not high.
