The radio resource configuration method includes that: a user equipment (UE) receives a message of a radio resource configuration from a first signaling radio bearer (SRB) of a first radio access technology (RAT), where the message carries information of a first configuration, and the first configuration is a configuration of a radio resource of the first RAT; and when the UE fails to configure the radio resource of the first RAT according to the information of the first configuration, the UE sends a response message of the radio resource configuration to indicate that the radio resource configuration of the first RAT fails. ## Claims ### Claim 1 A method comprising: sending, by a first network element using a first radio access technology (RAT) between the first network element and a user equipment (UE), and via a first signaling radio bearer (SRB) of the of the first RAT, a radio resource configuration to the UE for configuring a resource of the first RAT;

and wherein processing, by the second network element, the message comprises: decoding, by the second network element, the report information; and performing, by the second network element, a radio resource management decision according to the report information. ### Claim 7 (depends on 4) The method of claim 4, wherein the report information is coded by using ASN.1 corresponding to the second RAT, and is carried in a container of the message and wherein processing, by the second network element, the message comprises: forwarding, by the second network element, the container to the first network element; and after the first network element decodes the report information in the container, performing, by the first network element, a radio resource management decision according to the report information. ### Claim 8 (depends on 6) The method of claim 6, wherein a result of the radio resource management decision is to release the first network element and in response to determining that the result of the radio resource management decision is to release the first network element, the method further comprises: notifying, by the second network element and through the second SRB, the UE to release the resource of the first RAT. ### Claim 9 (depends on 6) The method of claim 6, wherein a result of the radio resource management decision is to switch the first network element and in response to determining that the result of the radio resource management decision is to switch the first network element, the method further comprises: receiving, by the second network element, reconfiguration information of a radio resource reconfiguration of a third RAT sent by a third network element after the first network element is switched; and sending, by the second network element, the reconfiguration information to the UE through the second SRB. ### Claim 10 (depends on 6) The method of claim 6, wherein a result of the radio resource management decision is to reconfigure the resource of the first RAT by the second network element and in response to determining that the result of the radio resource management decision is to reconfigure the resource of the first RAT by the second network element, the method further comprises: receiving, by the second network element, reconfiguration information of a radio resource reconfiguration of the first RAT from the first network element;
