Abstract: This application provides a method and an apparatus for verifying a personal identification number PIN code. When a first SIM card is inserted into a powered-on terminal device or the terminal device into which the first SIM card is inserted is powered on, whether a mapping relationship includes a PIN code to which a first ICCID of the first SIM card is mapped is queried; the PIN code is sent to the first SIM card if the mapping relationship includes the PIN code to which the first ICCID is mapped; and a verification result of the PIN code from the first SIM card is received.

Abstract: This application discloses methods and apparatuses for radio frequency channel sharing. An example method includes sending, by a terminal, first user equipment (UE) capability information to a network side device after receiving UE capability enquiry signaling that is sent by the network side device for a first subscriber identity module (SIM) card. The example method further includes sending, by the terminal, second UE capability information to the network side device after receiving UE capability enquiry signaling that is sent by the network side device for a second SIM card, wherein radio frequency capability information in the first UE capability information is the same as radio frequency capability information in the second UE capability information.

The first SIM card interface is configured to communicate with a first SIM card, and the second SIM card interface is configured to communicate with a second SIM card. The terminal is configured to, when the terminal is in a first communication connection, receive a paging request for establishing a second communication connection, and when the paging request carries a first identifier indicating a second service, respond to the paging request to establish the second communication connection.

Abstract: A terminal first connects to a 5th generation (5G) standalone (SA) network and initiates a call to another terminal by using a Voice over New Radio (VoNR) technology. When the terminal fails to call the other terminal, the terminal disconnects from the 5G SA network, connects to a Long-Term Evolution (LTE) network, and then automatically initiates a call to the other terminal by using a Voice over LTE (VoLTE) technology.

Abstract: A terminal device comprising a transceiver, a memory, and a processor is provided. The terminal device may send in a network, an IMS registration request to a network device in the network, and may start an IMS timer corresponding to the network. If the terminal device does not receive a registration accept message from the network device when the IMS timer expires, the terminal device deactivates the network. The network may be one of a first network and a second network, the network device may be one of a first network device and a second network device, and each of the first network and the second network corresponds to an IMS timer with a different duration. In this way, different waiting durations may be provided for IMS registration processes in different networks, to improve user communication experience.

Abstract: A terminal supporting dual-receive single-transmit dual-card dual-standby single-pass includes a first subscriber identity module (SIM) card interface and a second SIM card interface. The first SIM card interface is configured to communicate with a first SIM card, and the second SIM card interface is configured to communicate with a second SIM card.

When the terminal receives the paging request for the second communications connection, if the terminal has a to-be-sent voice packet of the first communications connection, the terminal delays responding to the paging request for setting up the second communications connection, or if the terminal has no to-be-sent voice packet of the first communications connection, the terminal responds to the paging request for setting up the second communications connection.

Abstract: This application provides a communication method and a terminal device. The terminal device includes a radio frequency transmit channel, a first SIM card interface, and a second SIM card interface. A method performed by the terminal device can include, when the terminal device needs to perform a first voice service, disconnecting the terminal device from the 5G network, and connecting the terminal device to a first LTE network by using the first SIM card. The method can also include performing the first voice service through the first LTE network, and receiving a first connection request from a second LTE network, where the first connection request is used to request the terminal device to perform a second voice service, and the second voice service is related to the second SIM card. Furthermore, the method can include responding to the first connection request by occupying the radio frequency transmit channel in a time division manner in a process of performing the first voice service.

Abstract: Embodiments of the present invention provide a method for improving voice call quality. The method is applied to a terminal, and the terminal includes a buffer module. When the buffer module includes voice data, the method includes: determining that the voice data buffered by the buffer module is in an accumulated state; and cutting off an SID frame in the voice data. To be specific, when the SID frame is detected and the voice data buffered by the buffer module is in the accumulated state, the SID frame in the voice data is cut off. The SID frame does not include semantic data. In this way, an amount of to-be-sent voice data is reduced, a packet loss and a sending delay are reduced, voice call quality is improved, and user experience is improved.

Abstract: Embodiments of this application provide a power consumption control method and an apparatus, relate to the field of communications technologies, and are used to reduce power consumption of user equipment and ensure communication performance of the user equipment.
