Description

Communication link management method, electronic device, readable storage medium, and chip Technical Field The present application relates to the field of communications technologies, and in particular, to a method for managing a communication link, an electronic device, a readable storage medium, and a chip. Background Various application programs are usually installed in the electronic device, and the application programs generally need to interact with the network side device in the running process, wherein the application programs comprise application data sent to the network side device. Currently, when an electronic device sends application data to a network side device, the application data is generally encapsulated into a plurality of internet protocol (internet protocol, IP) messages on an application processor (application processor, AP) side, and then the encapsulated IP messages are sequentially sent to a communication chip (communication processor, CP) for sending. It should be noted that, in the above process, when the IP packet reaches the CP, if the CP and the radio access network (radio access network, RAN) device do not establish a communication link, the CP needs to wait for the communication link to be established before the CP can start sending the IP packet, which results in a slower sending speed of the IP packet. It can be appreciated that in a scenario with severe delay requirements, the slow sending speed of the IP packet may result in poor user experience. For example, in the scenario of ticketing, redbook, stock trading, or entering an application front page, it may result in a user failing to ticket/redbook/stock trading, or the application front page opening slower. Disclosure of Invention The application provides a communication link management method, electronic equipment, a readable storage medium, a chip method and a device, which are used for solving the problem of low IP message sending speed in the prior art. In order to achieve the above purpose, the application adopts the following technical scheme: In a first aspect, an embodiment of the present application provides a method for managing a communication link, where the method is applied to an electronic device, where the electronic device includes an application processor AP and a communication processor CP, and the electronic device does not have a well established communication link, and the method includes, in response to a first event, the AP sending a network preheating command to the CP before sending an IP packet to the CP, where the IP packet is a first packet predicted to be sent by the AP, and the CP establishes a communication link with a radio access network device according to the network preheating command. By the method provided by the embodiment of the application, the CP starts to establish the communication link in advance before the first IP message reaches the CP from the AP, so that the CP can quickly send the IP message through the communication link after the first IP message reaches the CP, the waiting time of the IP message on the CP side is shortened or avoided, the sending speed of the first IP message can be improved, and the sending time delay of the first IP message is reduced. It can be understood that under the scenes of purchasing, ticket-taking, red-taking, stock trading, opening application front page and the like, the electronic equipment can be quickly communicated with the network side equipment based on the method, the possibility of success of the ticket-taking/red-taking and the stock trading is improved, the speed of opening the application front page is improved, and better user experience is achieved. In some embodiments, the method further comprises the AP sending an IP message to the CP after sending the network pre-heat command to the CP, the CP sending the IP message over the communication link. It can be seen that in this embodiment, the generation of the IP packet and the packet relocation from the AP to the CP are performed in parallel with the network preheating process. Compared with the serial process of message generation and relocation and network preheating, the parallel processing mode reduces the waiting time of the IP message after reaching the CP, and can rapidly send out the arrived IP message. In some embodiments, the network warm-up command includes at least one of first time information, an amount of uplink data, and a link type. It can be appreciated that the CP can perform network warm-up more accurately according to the first time information, the uplink data amount, and the link type. In some embodiments, the first time information is a start time of a predicted upcoming network task, or the first time information is a predicted time for the IP message to reach the CP, or the first time information is a time for the CP to start network warm-up. In this embodiment, according to the first time information, the CP may more accurately control the start t
