A method for overriding low priority and/or Extended Access Bar, EAB, comprising: sending, by an Open Mobile Alliance, OMA, Device Management, DM, server, a low priority overriding indicator and/or an EAB overriding indicator to dual-priority User Equipment, UE; storing, by the dual-priority UE, the low priority overriding indicator and/or the EAB overriding indicator in a Universal Subscriber Identity Module, USIM, card; and determining, by the dual-priority UE, whether to override low priority and/or EAB according to the low priority overriding indicator and/or the EAB overriding indicator; characterized in that, determining, by the dual-priority UE, whether to override low priority and/or EAB according to the low priority overriding indicator and/or the EAB overriding indicator comprises that: if the dual-priority UE determines that the low priority overriding indicator and/or the EAB overriding indicator are/is in the USIM card, and the low priority overriding indicator and/or the EAB overriding indicator indicate/indicates permission to override the low priority and/or the EAB, then the dual-priority UE overrides the low priority and/or the EAB, and initiates a normal priority request to a 3rd Generation Partnership Project, 3GPP, network side; or else, the dual-priority UE does not override the low priority and/or the EAB, and fails to initiate a normal priority request to the 3GPP network side. sending, by an Open Mobile Alliance, OMA, Device Management, DM, server, a low priority overriding indicator and/or an EAB overriding indicator to dual-priority User Equipment, UE; storing, by the dual-priority UE, the low priority overriding indicator and/or the EAB overriding indicator in a Universal Subscriber Identity Module, USIM, card; and determining, by the dual-priority UE, whether to override low priority and/or EAB according to the low priority overriding indicator and/or the EAB overriding indicator; characterized in that, determining, by the dual-priority UE, whether to override low priority and/or EAB according to the low priority overriding indicator and/or the EAB overriding indicator comprises that: if the dual-priority UE determines that the low priority overriding indicator and/or the EAB overriding indicator are/is in the USIM card, and the low priority overriding indicator and/or the EAB overriding indicator indicate/indicates permission to override the low priority and/or the EAB, then the dual-priority UE overrides the low priority and/or the EAB, and initiates a normal priority request to a 3rd Generation Partnership Project, 3GPP, network side; or else, the dual-priority UE does not override the low priority and/or the EAB, and fails to initiate a normal priority request to the 3GPP network side. if the dual-priority UE determines that the low priority overriding indicator and/or the EAB overriding indicator are/is in the USIM card, and the low priority overriding indicator and/or the EAB overriding indicator indicate/indicates permission to override the low priority and/or the EAB, then the dual-priority UE overrides the low priority and/or the EAB, and initiates a normal priority request to a 3rd Generation Partnership Project, 3GPP, network side; or else, the dual-priority UE does not override the low priority and/or the EAB, and fails to initiate a normal priority request to the 3GPP network side.
