Description

Terminal, network registration method thereof and computer readable storage medium Technical Field The present application relates to the field of terminal technologies, and in particular, to a terminal and a network registration method thereof, and a computer readable storage medium. Background In the prior art, some 5G dual card terminals employ design logic in which the 5G capability follows the data card, i.e., the 5G capability of the terminal is only bound to the SIM card currently set by the user as the "data card" (or "master card"). While the other SIM card, which is a "non-data card" (or "secondary card"), has its 5G capability disabled by default on the terminal side, even though the SIM card itself supports 5G. When the user switches the data card from the card 1 to the card 2, the following flow is triggered that the card 2 initiates a TAU (TrackingAreaUpdate ) request to the network side, and indicates "the wireless capability of the terminal has been updated" to the network side through a flag bit in the request, the network side shall initiate UE capability query signaling to the terminal immediately after receiving the TAU request, and then the terminal sends its 5G capability parameter to the network side, and the network side completes the 5G network registration after receiving, thereby enabling the card 2 to use the 5G service. However, due to the influence of factors such as policy implementation, signaling optimization or load consideration, the network side cannot initiate UE capability query signaling immediately after receiving the TAU request, which causes that the network side cannot learn the 5G capability parameters of the card 2, so that a subsequent 5G network registration procedure cannot be initiated for the card 2, the card 2 cannot successfully register with the 5G network, and can only register with the 4G network, and finally, the user cannot enjoy the 5G high-speed data service, and the user experience is affected. Accordingly, improvements in the art are needed. The above information is presented as background information only to aid in the understanding of the application and is not intended to determine or acknowledge whether any of the foregoing is useful as prior art with respect to the application. Disclosure of Invention The application provides a terminal, a network registration method thereof and a computer readable storage medium, which are used for solving the problem that the terminal cannot register a 5G network because the network does not initiate UE capability inquiry when a data card is switched in the prior art. In order to achieve the above object, the present application provides the following technical solutions: In a first aspect, an embodiment of the present application provides a terminal network registration method, where the terminal includes a first SIM card and a second SIM card, one of the first SIM card and the second SIM card is configured as a data card, the other is configured as a non-data card, and a 5G capability of the terminal is only bound to the data card, the terminal network registration method includes: When the first SIM card is switched from the non-data card to the data card, monitoring whether a network side initiates UE capability inquiry signaling to the terminal; If not, the first SIM card initiates a re-registration request to the network side so as to drive the network side to send UE capability query signaling to the first SIM card, the first SIM card reports a 5G capability parameter after receiving the UE capability query signaling, and the network side completes 5G network registration according to the 5G capability parameter. Optionally, the monitoring whether the network side initiates the UE capability query signaling to the terminal includes: judging whether the first SIM card initiates a tracking area update request to the network side, and whether the tracking area update request indicates that the current UE wireless capability is updated or not; If yes, detecting whether the network side returns the UE capability query signaling within the preset time after the tracking area update request is initiated, and if not, judging that the network side does not initiate the UE capability query signaling to the terminal. Optionally, the first SIM card initiates a re-registration request to the network side, including: detecting whether the terminal currently has data or voice service in progress; if yes, initiating the registration request after the service is ended; if not, the registration request is immediately initiated. Optionally, the detecting whether the terminal currently has data or voice service in progress includes: Detecting whether the current uplink and downlink data rate exceeds a preset rate threshold and the duration exceeds a preset duration threshold, if yes, judging that the current data service is in progress; and detecting whether an active call state exists currently, and if so, judging that
