The mobile terminal may include more or fewer components than shown, or may combine certain components, or arrange the components differently.
[0095] The following is a detailed introduction to the various components of the mobile terminal in conjunction with Figure 1:
[0096] The RF unit 101 can be used to send and receive information or receive signals during calls. Specifically, it receives downlink information from the base station and transmits it to the processor 110 for processing. It also transmits uplink data to the base station. Typically, the RF unit 101 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier, a duplexer, and / or other components.

The image frames processed by the GPU 1041 may be stored in the memory 109 (or other storage medium) or transmitted via the RF unit 101 or the WiFi module 102. The microphone 1042 may receive sound (audio data) in operating modes such as a phone call mode, a recording mode, and a voice recognition mode, and may process such sound into audio data. In the phone call mode, the processed audio (voice) data may be converted into a format that can be transmitted to a mobile communication base station via the RF unit 101. The microphone 1042 may implement various types of noise cancellation (or suppression) algorithms to eliminate (or suppress) noise or interference generated during the reception and transmission of audio signals.
[0100] The mobile terminal 100 also includes at least one sensor 105, such as a light sensor, a motion sensor, and other sensors.

The touch panel 1071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch direction and detects the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device and converts it into touch point coordinates, which are then sent to the processor 110. It can also receive and execute commands sent by the processor 110. And / or, the touch panel 1071 can be implemented using various types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 1071, the user input unit 107 may further include other input devices 1072.

[0252] In existing protocols, conditional handover is only applicable once, meaning that all conditional handover configurations are released after the terminal device completes the conditional handover.

Optionally, the current serving cell receives the response message and sends early data forwarding signaling feedback to the third network device to perform early data forwarding.
[0267] Optionally, when there is at least one other candidate cell (including a third network device) that meets the conditions for switching the measurement configuration, the terminal device can also send a measurement report (indication information) to the current serving cell (i.e., the second network device), thereby enabling the second network device to perform early data forwarding according to the indication information.
[0268] Optionally, the terminal device continuously evaluates whether there are candidate cells that meet the conditions to execute conditional configuration.
