Description

Communication method and apparatus, computer program product, and readable storage medium Technical Field The present invention relates to the field of wireless communication technology, and in particular, to a communication method and apparatus, a computer program product, and a readable storage medium. Background Discontinuous coverage techniques are an effective way to increase network coverage efficiency. For example, in a satellite communication system, the coverage area of a satellite may be made up of a plurality of wave positions, and the coverage area of a wave position may have a diameter of several tens of kilometers. For each wave position, coverage and service may be provided by one beam (beam). In view of the limited power at the satellite side, antenna configuration, etc., satellites typically cannot provide a large number of beams simultaneously to cover each wave position. Typically, the satellite side needs to implement beam coverage for each wave position by means of time division multiplexing (Time Division Multiplexing, TDM), which in turn results in that the time for each cell in the satellite coverage area to be covered by a beam is discontinuous. In a discontinuous coverage scenario, how to reduce the delay of a terminal device accessing a network is a problem to be solved. Disclosure of Invention The invention at least aims to provide a communication method which can reduce the time delay of terminal equipment accessing to a network. In a first aspect, the invention provides a communication method comprising the steps of sending a random access request message, and carrying out data transmission based on a second discontinuous transmission duration, wherein the second discontinuous transmission duration comprises at least one of a second discontinuous reception duration for data transmission and a second discontinuous transmission duration for data reception, and the second discontinuous transmission duration is different from a preconfigured first discontinuous transmission duration. The terminal device determines a second discontinuous transmission duration, the second discontinuous transmission duration being different from the preconfigured first discontinuous transmission duration. By using a second discontinuous transmission duration longer than the preconfigured first discontinuous transmission duration, the terminal device can perform data transmission within the longer discontinuous transmission duration, and further can complete a random access process within one discontinuous transmission period, so that the time delay of the terminal device accessing the network can be reduced. Optionally, the first discontinuous transmission time comprises at least one of a first discontinuous transmission time and a first discontinuous reception time, wherein the first discontinuous transmission time comprises a preconfigured discontinuous transmission time in which a random access response message is located, the random access response message is responsive to the random access request message, the first discontinuous reception time comprises a preconfigured discontinuous reception time at least partially overlapped with the first discontinuous transmission time in a time domain, or a first preconfigured discontinuous reception time located after the first discontinuous transmission time in a time domain. Optionally, the second discontinuous transmission duration is determined based on the first discontinuous transmission duration and a first time length, and the first time length is carried by first indication information. The network device may indicate the first duration through the first indication information. The terminal equipment determines a first duration based on the first indication information, and further obtains a second discontinuous transmission duration based on the first discontinuous transmission duration and the first duration. Optionally, the second discontinuous transmission duration is a discontinuous transmission duration formed by extending the first discontinuous transmission duration by the first duration. The terminal device may directly extend the first discontinuous transmission duration by a first duration to obtain a second discontinuous transmission duration. Optionally, the first indication information is further used for indicating a first time domain starting position, the second discontinuous transmission duration time includes the first discontinuous transmission duration time and an extended time window, the time domain starting position of the extended time window is the first time domain starting position, and the duration of the extended time window is the first duration. The network device indicates a first duration and a first time domain starting position through the first indication information. The terminal device may determine an extended time window based on the first indication information. The terminal device may perform discontinuou
