Abstract: An electrical connector with HDMI 2.1 specification, including an insulating body, multiple terminals, and a metallic shell partially enclosing the insulating body and the terminals, is provided. The terminals include ten terminals located in an upper row and nine terminals located in a lower row. The ten terminals are sequentially a first terminal Data2+, a third terminal Data2?, a fifth terminal Data Shield, a seventh terminal Data0+, a ninth terminal Data0?, a eleventh terminal Data3 Shield, a thirteenth terminal CEC, a fifteenth terminal SCL, a seventeenth terminal DDC/CEC Ground, and a nineteenth terminal Hot Plug Detec1 along an arrangement direction. The nine terminals are sequentially a second terminal Data2 Shield, a fourth terminal Data1+, a sixth terminal Data1?, an eighth terminal Data0 Shield, a tenth terminal Data3+, a twelfth terminal Data3?, a fourteenth terminal Utility, a sixteenth terminal SDA, and an eighteenth terminal +5V Power along the arrangement direction.

Abstract: A network standard switching method includes obtaining a network standard switching instruction including a target priority. The network standard switching instruction instructs a terminal device to be handed over to a target network whose standard is a target standard, and a priority of the target network is greater than a priority of a network in which the terminal device is currently located. The method further includes releasing a network link between the terminal device and a currently accessed first base station, intercepting and caching to-be-sent application-layer data of the terminal device, discarding a paging message in a packet switched (PS) domain received from a first-priority network to the terminal device, and handing over to the target network.
