An operation control method, applied to a mobile communications terminal comprising: receiving logical channel prioritization, LCP, restriction configuration signaling sent by a network-side device, wherein the LCP restriction configuration signaling carries LCP restriction rules; and performing a management operation on a target LCP restriction rule in the LCP restriction rules, wherein the management operation is a deactivate operation or an activate operation; wherein after the receiving the logical channel prioritization, LCP, restriction configuration signaling sent by the network-side device and before the performing the management operation on the target LCP restriction rule in the LCP restriction rules, the method further comprises: receiving operation control information sent by the network-side device, wherein the operation control information is used by the mobile communications terminal to determine the target LCP restriction rule and the management operation; or, wherein before the performing the management operation on the target LCP restriction rule in the LCP restriction rules, the method further comprises: receiving operation control information sent by the network-side device, wherein the operation control information is used by the mobile communications terminal to determine the target LCP restriction rule and the management operation; wherein the operation control information is carried in the LCP restriction configuration signaling; wherein the operation control information comprises a trigger condition for performing the management operation on the target LCP restriction rule; and the performing the management operation on a target LCP restriction rule in the LCP restriction rules comprises: when the trigger condition holds true, performing the management operation on the target LCP restriction rule in the LCP restriction rules. receiving logical channel prioritization, LCP, restriction configuration signaling sent by a network-side device, wherein the LCP restriction configuration signaling carries LCP restriction rules;
