摘要： Aspects of the disclosure provide a network switching method, device, and storage medium. In an exemplary method, a terminal may determine whether a target wireless access network is capable of establishing a connection with an IP Multimedia Subsystem (IMS) network. If the target wireless access network is capable of establishing the connection with the IMS network, then a wireless access network corresponding to the terminal can be switched to the target wireless access network.

摘要： The present disclosure relates to a wireless communication device and a method for switching an antenna of a wireless communication device that includes a first antenna in an operation state and a second antenna in a standby state. The method includes detecting a first performance parameter of the first antenna, the first performance parameter including at least one of a strength of a received signal at the first antenna and a sensitivity of the first antenna; and when the first performance parameter of the first antenna is lower than a preset threshold, switching the second antenna to the operation state, and switching the first antenna to the standby state. The technical solution can improve a communication quality of the wireless communication device by enabling a standby antenna when performance of an antenna in the operation state has been degraded.

摘要： The present disclosure relates to methods and devices for identifying short messages received by mobile terminals as being from pseudo base stations, wherein, the method comprises: obtaining feature information of the short message when the mobile terminal receives the short message, wherein the feature information includes content information; judging whether the short message is suspected to be an annoying short message based on the feature information; obtaining, when it is judged that the short message is suspected to be an annoying short message, an operation time of when the mobile terminal performed a cell reselection operation with a location area update, wherein the operation time is closest in time to when the mobile terminal received the short message; determining whether the short message is an annoying short message from a pseudo base station based on the operation time. In the technical feature, information security of user terminals may be enhanced.

摘要： A method, apparatus and computer-readable medium are provided for voice call in mobile communication technologies. The method may include: displaying at least one contact when an instruction for viewing contact information is received, the at least one contact including a plurality of pieces of contact information and a plurality of pieces of network service status, the network service status indicating whether corresponding contact terminal currently supports IMS based voice service; determining, when a selection instruction for selecting target contact information is received, call parameter range supported by a target contact terminal based on target network service status; and transmitting a request for voice call to a core network equipment.

摘要： A method for a device to perform cell reselection, includes: when the device resides in a current serving cell, determining whether a neighboring cell meets a cell reselection condition; if the neighboring cell meets the cell reselection condition, obtaining cell reselection information corresponding to the neighboring cell; determining whether the cell reselection information matches any one of one or more historical ping-pong reselection records; if the cell reselection information matches a first historical ping-pong reselection record of the one or more historical ping-pong reselection records, determining whether a time difference between a current cell reselection time and a historical cell reselection time corresponding to the first historical ping-pong reselection record is greater than a preset time difference; and if the time difference is greater than the preset time difference, reselecting the neighboring cell as a current serving cell.
