A voice call control method includes: measuring a target cell during a voice call; reporting a measurement result when the measurement result satisfies a measurement report optimization condition in which it is included to improve a measurement report condition for the terminal to make a handover to an anchor cell with a current network type; receiving a report response of the measurement result, and making a handover to the target cell to perform a voice call based on the report response of the measurement result. As such, a probability of occurrence of silence or disconnection during a voice call can be reduced.

Voice call control method, voice call control device, and storage medium

A method for sending a measurement report, includes: after receiving an enable signal of a second network, a first modem starting up a timer and sending a startup signal to a second modem; when the timer expires, the first modem sending a tracking area update (TAU) request to a network side device; the first modem receiving a measurement configuration sent by the network-side device, and instructing the second modem after startup to measure the second network according to the measurement configuration to obtain a measurement report; and reporting the measurement report to the network-side device.

Method, apparatus, terminal and storage medium for measurement report

A method and an apparatus for processing a paging message can be applied to a terminal device supporting a plurality of Subscriber Identification Module (SIM) cards. The method includes: a target paging message corresponding to a SIM card of a current paging cycle from a network side is received; it is determined whether the target paging message belongs to a spam message paging a slave SIM card, wherein the slave SIM card is any one of the plurality of SIM cards that does not provide a data service; and the target paging message is discarded when the target paging message belongs to the spam message paging the slave SIM card.

Method and apparatus for processing paging message

The present disclosure provides a method and a device for retransmitting a short message, and a storage medium. The method includes: after transmitting a short message, determining whether the short message can be successfully retransmitted based on a cause value of an error message in response to receiving the error message transmitted back from a network side; and determining whether to retransmit the short message based on a result of determining whether the short message can be successfully retransmitted.

Method and device for retransmitting short message, and storage medium

A method, device and medium for determining a coding format are provided. The method includes: receiving one or more data packets forwarded by a call center during a VoLTE communication, in which the one or more data packets carry a first coding format; detecting whether the first coding format is same with a negotiated second coding format; and modifying the coding format used during the VoLTE communication from the second coding format to the first coding format, if the first coding format is not same with the negotiated second coding format.

Method, device and medium for determining coding format

A method for accessing a base station is provided. The method includes: identifying, by a terminal device, a target base station providing a maximum received signal strength from at least one base station; receiving a system message sent by the target base station, the system message including an access parameter associated with the target base station; if a value of the access parameter satisfies a preset condition, accessing the target base station; and if the value of the access parameter does not satisfy the preset condition, maintaining access to a base station currently accessed by the terminal device.

Method and apparatus for accessing base station
