Description

This application claims priority to Chinese Patent Application No. 202311044447.4, filed with the China National Intellectual Property Administration on August 17, 2023 and entitled "COMMUNICATION METHOD, ELECTRONIC DEVICE, AND READABLE STORAGE MEDIUM", which is incorporated herein by reference in its entirety. TECHNICAL FIELD This application relates to the field of communication technologies, and specifically, to a communication method, an electronic device, and a computer-readable storage medium. BACKGROUND To reduce power consumption, a discontinuous reception (discontinuous reception, DRX) technology is introduced in a communication system. A DRX cycle including a sleep period and an active period is configured for user equipment (user equipment, UE), so that the UE monitors a physical downlink control channel (physical downlink control channel, PDCCH) in the active period to receive downlink data, but does not receive downlink data in the sleep period. Specifically, a network device may set, based on the foregoing DRX technology, a default DRX cycle corresponding to a network standard to which the network device belongs. The UE may report a required specific DRX cycle to a network device of a network standard of the UE based on a service scenario. For example, the UE may report a short customized DRX cycle to the network device based on a low-delay service scenario, to shorten a time interval of receiving service data and reduce a service delay. Refer to a schematic diagram of a paging scenario shown in FIG. 1. After UE 100 reports a customized DRX cycle in a current network standard (for example, a 4G network), the UE 100 and a network device of the current network standard may use the customized DRX cycle as a paging cycle. For example, a base station 200 of the current network standard sends a paging message based on the customized DRX cycle, and the UE 100 receives a paging message based on the customized DRX cycle. However, after the UE 100 is migrated to a target network standard (for example, a 5G network), because a DRX cycle at which a network device (for example, a base station 300) of the target network standard sends a paging message does not match a DRX cycle at which the UE 100 receives a paging message, paging fails and consequently, a call missing phenomenon may occur. SUMMARY This application provides a communication method, an electronic device, and a computer-readable medium. This can avoid a call missing phenomenon caused because a DRX cycle of user equipment does not match a DRX cycle of a target network standard, to improve a call experience of a user. According to a first aspect, this application provides a communication method, including: User equipment assesses a first network standard via a first network device, where the user equipment and the first network device perform paging based on a first paging cycle; the user equipment receives a first instruction for handover from the first network standard to a second network standard; and the user equipment sends a paging cycle change instruction, where the paging cycle change instruction is used for causing a paging cycle of the user equipment to be the same as a paging cycle of a second network device corresponding to the user equipment after the user equipment accesses the second network standard. The first paging cycle may be a customized DRX cycle shorter than a default DRX cycle of the first network standard, the first network standard may be a current network standard of the user equipment, and the second network standard may be a target network standard of the user equipment. The user equipment may report a required customized DRX cycle to the first network standard based on a requirement of a low-delay service, and further, the user equipment may use a shorter customized DRX cycle as a paging cycle for paging with the first network device in the first network standard. It may be understood that the customized DRX cycle reported by the user equipment to the first network standard takes effect only in the first network standard, in other words, only in the first network standard, the user equipment uses the customized DRX cycle as a paging cycle for receiving a paging message. If the user equipment accesses another network standard and does not report the customized DRX cycle in the another network standard, the user equipment is to use a default DRX cycle of the another network standard as a paging cycle for receiving a paging message. However, for the first network standard with a function of synchronizing a DRX cycle, when determining that the user equipment is to be handed over to the another network standard, the first network standard may synchronize the customized DRX cycle reported by the user equipment in the first network standard to the another network standard, to cause the another network standard to use the customized DRX cycle as a paging cycle for sending a paging message. Based on the foregoing situation,
