A method for rejecting auxiliary information about user equipment, comprising: a network side configured to decide how to optimize a wireless parameter of the user equipment according to the auxiliary information receiving the auxiliary information reported by the user equipment, transmitting rejection reason information to the user equipment when it is determined not to reconfigure the wireless parameter; wherein the rejection reason information comprises: the network side being heavily loaded; or the network side being overloaded; or a current wireless parameter configuration of the user equipment being matched with the auxiliary information reported by the user equipment and there being no need of reconfiguring the wireless parameter of the user equipment; or the current wireless parameter configuration having reached an adjustable limit, and failing to meet requirements of the auxiliary information reported by the user equipment; wherein the user equipment considers that the network side access network element rejects the auxiliary information of the user equipment when the user equipment receives the rejection reason information transmitted by the network side within a first preset time length after transmitting the auxiliary information, and confirms whether to continue to transmit the auxiliary information after considering that the network side rejects the auxiliary information as follows:the user equipment limits a transmission frequency of the auxiliary information when the rejection reason is the network side being heavily loaded or the network side being overloaded; and when the rejection reason is that there is no need of reconfiguring a wireless parameter since a current wireless parameter configuration of the user equipment is matched with the auxiliary information reported by the user equipment, or when the rejection reason is that the current wireless parameter configuration has reached an adjustable limit but still fails to meet requirements of the auxiliary information reported by the user equipment, the user equipment does not transmit a newly triggered auxiliary information when a new auxiliary information is triggered by the user equipment and the newly triggered auxiliary information is the same as the auxiliary information. a network side configured to decide how to optimize a wireless parameter of the user equipment according to the auxiliary information receiving the auxiliary information reported by the user equipment, transmitting rejection reason information to the user equipment when it is determined not to reconfigure the wireless parameter; wherein the rejection reason information comprises: the network side being heavily loaded; or the network side being overloaded; or a current wireless parameter configuration of the user equipment being matched with the auxiliary information reported by the user equipment and there being no need of reconfiguring the wireless parameter of the user equipment; or the current wireless parameter configuration having reached an adjustable limit, and failing to meet requirements of the auxiliary information reported by the user equipment; wherein the user equipment considers that the network side access network element rejects the auxiliary information of the user equipment when the user equipment receives the rejection reason information transmitted by the network side within a first preset time length after transmitting the auxiliary information, and confirms whether to continue to transmit the auxiliary information after considering that the network side rejects the auxiliary information as follows:the user equipment limits a transmission frequency of the auxiliary information when the rejection reason is the network side being heavily loaded or the network side being overloaded; and when the rejection reason is that there is no need of reconfiguring a wireless parameter since a current wireless parameter configuration of the user equipment is matched with the auxiliary information reported by the user equipment, or when the rejection reason is that the current wireless parameter configuration has reached an adjustable limit but still fails to meet requirements of the auxiliary information reported by the user equipment, the user equipment does not transmit a newly triggered auxiliary information when a new auxiliary information is triggered by the user equipment and the newly triggered auxiliary information is the same as the auxiliary information.
