Browsing the web, downloading various materials, performing voice services, etc., but due to the bandwidth limitation of GSM or LTE, when the downloaded data is too large, it will cause network congestion, and downloading data through GSM or LTE consumes a lot of bandwidth. services, which will cause high costs, and make the access network resources such as GSM or LTE unreasonable; or, the mobile phone used by the user is using the Wi-Fi network. At this time, the user wants to perform voice services, but, Wi-Fi is generally not used for voice services.
