1. An access control method, applied to a terminal, comprising:
receiving network side access association information sent by a network side, wherein the network side access association information comprises first information, and the first information indicates a bandwidth of an initial bandwidth part of a target cell, or a bandwidth of a default bandwidth part, or a bandwidth of a first activated bandwidth part; and
when the terminal does not support the bandwidth of the initial bandwidth part, or the bandwidth of the default bandwidth part, or the bandwidth of the first activated bandwidth part, performing access control processing on the target cell according to the network side access association information; wherein
the network side access association information further comprises access assistance information, and the access assistance information comprises at least one of:
second information, indicating whether a cell allows access by the terminal that does not support the bandwidth of the initial bandwidth part, or the bandwidth of the default bandwidth part, or the bandwidth of the first activated bandwidth part;
third information, indicating whether the cell supports flexible scheduling limitation;
fourth information, indicating a minimum bandwidth supported by the cell; or
fifth information, indicating that when the terminal does not support the bandwidth of the initial bandwidth part of the cell, or the bandwidth of the default bandwidth part, or the bandwidth of the first activated bandwidth part, forbidding access to the cell; wherein
the performing access control processing on the target cell according to the network side access association information comprises:
when the second information or the third information indicates “no”, forbidding access to the target cell; or
when the terminal does not support a minimum bandwidth indicated by the fourth information, forbidding access to the target cell; or
when the second information or the third information indicates “no”, or the terminal does not support the minimum bandwidth part indicated by the fourth information, sending the terminal side access association information; or
when a first preset condition is met, sending the terminal side access association information, wherein that the first preset condition is met comprises that: the second information or the third information indicates “no” and the enabling indication sent by the network side is allowing; or the terminal does not support the minimum bandwidth part indicated by the fourth information and the enabling indication sent by the network side is allowing; or
when the second information or the third information indicates “no”, or the terminal does not support the minimum bandwidth part indicated by the fourth information, sending terminal side access association information; receiving access indication information determined by the network side based on the terminal side access association information; and when the access indication information indicates rejecting access by the terminal, forbidding access to the target cell; or
when a second preset condition is met, sending terminal side access association information; receiving access indication information determined by the network side based on the terminal side access association information; and when the access indication information indicates rejecting access by the terminal, forbidding access to the target cell, and wherein
the second preset condition being met comprises that: the second information or the third information indicates “no” and the enabling indication sent by the network side is allowing; or the terminal does not support the minimum bandwidth part indicated by the fourth information and the enabling indication sent by the network side is allowing.
