A voice service processing method includes: sending, by a terminal device, a first message to a network device of a first network, where the first message requests a circuit switched fallback (CSFB) voice service; receiving, by the terminal device, a second message sent by the network device of the first network, where the second message instructs the terminal device to perform a network redirection; if the second message carries no frequency information, determining, by the terminal device, a redirection frequency, where the redirection frequency is a frequency supported by a second network; and sending, by the terminal device based on the redirection frequency, a connection request to a network device of the second network, to perform a circuit switched (CS) voice service.

Voice service processing method and terminal device

This application relates to the field of communications technologies, and provides a cell handover method and an apparatus in a high-speed movement scenario, to resolve problems of a relatively high service drop rate and a relatively high re-establishment rate of a terminal device in the high-speed movement scenario. The method includes: enabling a high-speed railway function of a terminal device; obtaining path information; determining a first target cell based on the path information; and reporting a first measurement report when a measurement value of a source cell meets a second threshold, where the first measurement report is used to trigger a network side device to control the terminal device to hand over from the source cell to the first target cell, and the source cell is a cell on which the terminal device camps, the second threshold is greater than a first threshold, and the first threshold is a threshold that is indicated by the network side device and that is used to trigger the terminal device to report a measurement report.

Cell handover method and apparatus in high-speed movement scenario

A cell selection method includes: when a terminal camps on a first network that does not support a voice service, and voice service needs to be initiated or received, falling back, by the terminal in a circuit switched fallback (CSFB) manner, to a second network that supports the voice service when the terminal fails to establish the voice service with the second network, saving, by the terminal, a location identifier of the first network and a location identifier of the second network to a blacklist. The blacklist is used by the terminal to choose to camp on a cell of the second network when performing CSFB subsequently.

The present invention provides a voice service processing method and a terminal device. The method includes: sending, by a terminal device, a first message to a network device of a first network, where the first message is used to request a circuit switched fallback CSFB voice service; receiving, by the terminal device, a second message sent by the network device of the first network, where the second message is used to instruct the terminal device to perform network redirection; if the second message carries no frequency information, determining, by the terminal device, a redirection frequency, where the redirection frequency is a frequency supported by a second network; and sending, by the terminal device based on the redirection frequency, a connection request to a network device of the second network, to perform a CS voice service.

A method related to the field of mobile communications technologies and for processing radio frequency resources includes detecting, by a terminal, a service mode of a first service that uses a primary subscriber identification module (SIM) card, where the service mode includes a real-time service mode and a non-real-time service mode, and reducing, by the terminal, a proportion of radio frequency (RF) resources occupied by a secondary SIM card when the service mode of the first service is the real-time service mode, where the primary SIM card is a card for performing the real-time service mode, and the secondary SIM card is a card, other than the primary SIM card, in a multi-SIM multi-standby terminal.

Method for processing radio frequency resources and terminal

Embodiments of the present disclosure include methods for keeping in a CSFB network and an example user terminal, wherein when a first call of a 4G user fails to be set up, the user terminal keeps in a target network accessed by circuit switched fallback (CSFB). In this way, when the 4G user receives a call request message for the second time, the user terminal does not need to perform CSFB, thereby increasing a call setup success rate. One example method includes obtaining, by a user terminal, a first call request message. The user terminal performs CSFB according to the first call request message to access a target network. The user terminal determines whether a call setup message is received. If no call setup message is received, the user terminal camps on the target network.

Method for keeping in circuit switched fallback CSFB network and user terminal

Embodiments of the present invention provide a call prompt method. A first interface that shows that a first terminal is in a call with a second terminal is displayed on the first terminal. If a third terminal initiates a call to the first terminal at this moment, a second interface indicating the call initiated by the third terminal is displayed on the first terminal, and a sound is output, where the sound includes a call voice and a prompt tone of the initiated call. If the call initiated by the third terminal to the first terminal is rejected, the call voice is output on the first terminal and the prompt tone stops to be output. Additionally or alternatively, if the third terminal stops initiating the call, the first interface is displayed on the first terminal, and the call voice between the first terminal and the terminal continues to be output.
