Call switching method, network platform and terminal

Abstract

The invention discloses a call switching method, a network platform and a terminal. The call switching method comprises the steps that the network platform monitors a call charge balance or a credit line balance of a calling party and calculates the remaining conversation time of the calling party according to the call charge balance or the credit line balance; when the remaining conversation time of the calling party is smaller than preset switching time, conversation between the calling party and a called party is switched from a CS domain to a PS domain. According to the call switching method, the network platform and the terminal, the mobile phone call charge balance or the credit line balance of the user can be detected; when the call charge balance or the credit line balance of the user is insufficient, the system automatically switches the conversation of the user from the CS domain to the PS domain, in this way, the situation that the user cannot converse continuously due to arrearage or credit line balance insufficiency is avoided, and meanwhile seamless switching can be achieved; the traffic usage conditions of the user can be detected in real time after the user enters voice conversation in the PS domain; furthermore, when package traffic is used out, conversation in the PS domain is interrupted in real time, and therefore the user is prevented from having excessive charges.
