1. A method for determining a target, comprising:
- acquiring, by a mobility management network element, access control information of a user equipment (UE);
sending, by the mobility management network element, the access control information of the UE to an access network element, wherein the access control information is for determination of a target radio access technology (RAT), and comprises an identity of a public land mobile network (PLMN) and at least one of a RAT allowed by the PLMN and a RAT not allowed by the PLMN; and
sending, by the mobility management network element to a home location register (HLR) or to a home subscriber server (HSS), a location update request message comprising a PLMN list and indication information, wherein the indication information requests subscription data corresponding to the identity of the PLMN, wherein before acquiring the access control information, the method comprises;
receiving, by the mobility management network element, subscription data from the HLR or from the HSS; and
wherein acquiring the access control information comprises acquiring, by the mobility management network element, the access control information according to the received subscription data.
