[0023] The embodiments of the present disclosure provide a communication method, a terminal, and a communication system.

[0024] In a first aspect, an embodiment of the present disclosure proposes a communication method, including: determining that a terminal is in a first call state, the first call state being used to indicate a state in which the terminal is conducting a voice call based on a wireless network WiFi; monitoring the signal quality of the WiFi; and, in response to the signal quality of the WiFi being lower than a quality threshold, performing call processing on the terminal.

[0025] In the above embodiment, by monitoring the WiFi signal quality, the signal quality of the voice call based on the wireless network WiFi can be obtained, and then corresponding call processing can be performed based on the WiFi signal quality of the current call of the terminal, avoiding the user from making a call in the first call state in an environment where the WiFi signal quality is lower than the quality threshold, thereby improving the user experience.

[0026] In combination with some embodiments of the first aspect, in some embodiments, performing call processing on the terminal includes: interrupting the first call state.

[0027] In the above embodiment, when the signal quality of WiFi is lower than the quality threshold, the terminal is interrupted in the first call state to avoid the user from continuing to maintain the first call state in this situation, thereby improving the user experience.

The conditions for terminating the first call state also include the failure to meet the conditions for switching to the second call state, allowing the call to be terminated even when switching to the second call state is not possible. This provides options other than call termination, such as switching to the second call state when the conditions for switching to the second call state are met, thereby improving the user experience.

[0037] In combination with some embodiments of the second aspect, in some embodiments, the processing module performs call processing on the terminal, including: determining that a condition for switching to the second call state is met, and switching to the second call state to conduct the call.

[0038] In combination with some embodiments of the second aspect, in some embodiments, after the processing module processes the call on the terminal, it also includes: updating the current WiFi signal quality to a WiFi signal quality that is lower than the quality threshold, and updating the current call status of the terminal to an interrupted call status.

[0075] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0082] VoWiFi refers to a technology that enables voice calls over wireless networks (Wireless Fidelity, WiFi). This technology solves the problem of devices being unable to send text messages, make phone calls, or perform other services when there's no base station signal or a weak cell signal.

[0083] In some embodiments, users can register with the IP Multimedia Subsystem (IMS) through a WiFi hotspot to conduct communication services, such as calls and text messages.

[0084] It should be understood that when registering for IMS services through a WiFi hotspot, the WiFi signal strength can affect the quality of the call service. For example, a weak WiFi signal can cause a voice call to be silent or intermittent. In this case, continuing to use VoWiFi as a call will severely impact the user experience.

[0085] Based on this, an embodiment of the present disclosure proposes a communication method, which enables the terminal to perform corresponding communication processing when the WiFi signal quality is not high to avoid the user continuing to maintain a call based on VoWiFi when the WiFi signal quality is not high.

[0086] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the embodiment of the present disclosure relates to a communication method, and the method includes:

[0106] In some embodiments, the second call state is used to indicate a state in which the terminal 101 is conducting a voice call based on a mobile network.

[0107] In some embodiments, terms such as "certain", "preset", "preset", "setting", "indicated", "a certain", "any", and "first" can be interchangeable. "Specific A", "preset A", "preset A", "setting A", "indicated A", "a certain A", "any A", and "first A" can be interpreted as A pre-specified in a protocol, etc., or as A obtained through setting, configuration, or indication, etc., or as specific A, a certain A, any A, or first A, etc., but not limited to this.

[0108] In step S2104, the terminal 101 updates the quality of the current WiFi signal and the current call status.

[0116] In some embodiments, the terminal 101 sends the first information to the network device 102 when the terminal 101 is in the first call state and the signal quality of the WiFi is greater than or equal to the quality threshold.

[0117] In some embodiments, after the terminal 101 performs call processing and is in the second call state, the first message is sent.

[0118] In some embodiments, after the terminal 101 performs call processing and is in the second call state, it sends the first information to the network device 102.

[0119] In some embodiments, network device 102 receives first information.

[0120] In some embodiments, the network device 102 receives the first information sent when the terminal 101 is in the first call state and the signal quality of the WiFi is greater than or equal to the quality threshold.

[0121] In some embodiments, the network device 102 receives the first information sent by the terminal 101 after the terminal 101 processes the call and is in the second call state.
