Method, device and equipment for realizing VoLTE service and computer storage medium

The invention discloses a method, a device and equipment for realizing a VoLTE (Voice over Long Term Evolution) service and a computer storage medium. The method comprises the following steps: determining the maximum number W of users who open an IMS PDN contract in unit time length according to the instruction processing capability of network equipment and the instruction processing capability ofa business operation support system BOSS interface; opening an IMS PDN subscription for Z users in the unit duration, wherein Z is smaller than or equal to W, W and Z are positive integers respectively, the Z users are users who do not open the VoLTE service respectively, and terminals of the Z users are terminals supporting the VoLTE service respectively; and after IMS PDN subscription is openedfor the Z users, opening VoLTE services for the Z users. According to the method provided by the embodiment of the invention, network congestion caused by simultaneously opening VoLTE services for alarge number of users can b
