Embodiment Construction
[0183] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.
[0184] figure 1 It is a schematic flowchart of a random access control method shown according to an exemplary embodiment. The random access control method shown in this embodiment may be applicable to user equipment, such as mobile phones, tablet computers, and the like. like figure 1 As shown, the random access control method in this embodiment may include the following steps.

The present disclosure relates to a random access control method, including: determining whether a random access response from the base station is received; if the random access response from the base station is not received, determining whether the first count value is equal to a first preset value ; If the first count value is not equal to the first preset value, determine whether the time window for monitoring and receiving the random access response corresponding to the preset time window is over; if it is over, the preamble transmission opportunity in the next preset time window will be sent to The base station sends the preamble, and the first count value is increased; if it is not finished, the preamble is sent to the base station at the next preamble transmission opportunity, and the first count value is increased; the above steps are repeated until the first count value is equal to the first preset value, or After receiving the random access response from the base station, stop sending the preamble to the base station. According to the embodiments of the present disclosure, it can avoid resource consumption of the user equipment and the base station caused by continuously resending the preamble to the base station when the user equipment determines that the random access to the base station fails.
Description
technical field [0001] The present disclosure relates to the technical field of terminals, and in particular to a random access control method, a random access control device, electronic equipment, and a computer-readable storage medium. Background technique [0002] In an LTE (Long Term Evolution, that is, 4G) system, a base station broadcasts a message to cover an area where the base station is located through a beam. The user equipment initiates random access to the base station, and only needs to send a beam in one direction once to be received by the base station. In this case, if the user equipment fails in random access, the counting value referenced for re-initiating random access may be counted according to the existing counting manner. [0003] However, in the NR (New radio, new air interface, that is, 5G) system, the base station covers the area where the base station is located by means of beam scanning, that is, the base station only sends a narrow beam in a ce...
