Problems solved by technology

Since VoWiFi cannot provide accurate location information of WLAN users, it has not been practically applied
[0004] In addition, in the application where WLAN users access and connect to mobile networks (for example, 4G / 5G networks), only authenticating users cannot guarantee the security of the network.

Abstract

The invention relates to a communication device and system and a computer readable storage medium, and relates to the technical field of communication. The method disclosed by the invention comprises the following steps: in response to registration of a terminal to a core network of a mobile network through an access network of a wireless local area network (WLAN), acquiring a device identifier and an access line identifier of an access point (AP) currently accessed by the terminal; authenticating the AP according to the device identifier and the access line identifier to determine whether a terminal connected to the AP is allowed to register to a core network of the mobile network; completing the registration of the terminal under the condition that the authentication of the AP is passed; in response to a WiFi-based voice VoWiFi call initiated by the terminal, receiving a network positioning message sent by a network element of a core network, the network positioning message comprising a device identifier; inquiring the position information of the AP corresponding to the stored equipment identifier; and sending the inquired position information of the AP to a network element of a core network to complete calling.

Description

technical field [0001] The present disclosure relates to the technical field of communication, and in particular, to a communication device, system and computer-readable storage medium. Background technique [0002] 4G LTE voice service VoLTE (Voice over LTE, LTE-based voice), in areas with poor LTE coverage, there will be problems such as inability to connect or call drops; in order to make up for the lack of VoLTE coverage, a WLAN (WirelessLocal Area Network, Wireless LAN) access VoWiFi (Voice over WiFi, voice over WiFi) solution. [0003] However, as a basic telecommunication service, the voice service must provide real-time and accurate user location traceability. Since VoWiFi cannot provide accurate location information of WLAN users, it has not been practically applied. [0004] In addition, in applications where WLAN users access and connect to mobile networks (for example, 4G / 5G networks), only authentication of users cannot guarantee network security.
