1. A method for determining a target, comprising:
- receiving, by an access network element, access control information of a user equipment (UE) that is sent by a mobility management network element, wherein the access control information comprises an identity of a public land mobile network (PLMN) and a radio access technology (RAT), wherein the access control information further comprises either information that the RAT is allowed by the PLMN or information that the RAT is not allowed by the PLMN, and wherein the PLMN is comprised in a PLMN list, and the PLMN list is one or a combination of the following PLMN lists;
a list of PLMNs supported by the mobility management network element or a subset of the PLMN list,a list of PLMNs equivalent to a PLMN supported by the mobility management network element or a subset of the PLMN list,a list of PLMNs equivalent to the PLMN serving the UE or a subset of the PLMN list;
a list of PLMNs that have a roaming or a cooperation agreement with a PLMN supported by the mobility management network element or a subset of the PLMN list;
a list of PLMNs that have a roaming or cooperation agreement with the PLMN serving the UE or a subset of the PLMN list,a list of PLMNs that belong to a same operator as a PLMN supported by the mobility management network element or a subset of the PLMN list, anda list of PLMNs that belong to a same operator as the PLMN serving the UE or a subset of the PLMN list; and
determining, by the access network element, a target RAT for the UE according to the access control information.

Abstract
Embodiments of the present invention disclose a method, a network element, and a system for determining a target RAT. The method includes: receiving, by an access network element, access control information of a UE that is sent by a mobility management network element, where the access control information includes an identity of a PLMN and a radio access technology RAT allowed and/or a RAT not allowed by the PLMN; and determining, by the access network element, a target RAT for the UE according to the access control information.

1. A method for determining a target, comprising:
-
receiving, by an access network element, access control information of a user equipment (UE) that is sent by a mobility management network element, wherein the access control information comprises an identity of a public land mobile network (PLMN) and a radio access technology (RAT), wherein the access control information further comprises either information that the RAT is allowed by the PLMN or information that the RAT is not allowed by the PLMN, and wherein the PLMN is comprised in a PLMN list, and the PLMN list is one or a combination of the following PLMN lists; a list of PLMNs supported by the mobility management network element or a subset of the PLMN list, a list of PLMNs equivalent to a PLMN supported by the mobility management network element or a subset of the PLMN list, a list of PLMNs equivalent to the PLMN serving the UE or a subset of the PLMN list;
a list of PLMNs that have a roaming or a cooperation agreement with a PLMN supported by the mobility management network element or a subset of the PLMN list;
a list of PLMNs that have a roaming or cooperation agreement with the PLMN serving the UE or a subset of the PLMN list,a list of PLMNs that belong to a same operator as a PLMN supported by the mobility management network element or a subset of the PLMN list, and a list of PLMNs that belong to a same operator as the PLMN serving the UE or a subset of the PLMN list; and determining, by the access network element, a target RAT for the UE according to the access control information. - View Dependent Claims (2, 3, 4, 5)

6. An access network element, comprising:
-
a receiver, configured to receive access control information of a user equipment (UE) that is sent by a mobility management network element, wherein the access control information comprises an identity of a public land mobile network (PLMN) and a radio access technology (RAT), wherein the access control information further comprises either information that-the RAT is allowed by the PLMN or information that the RAT is not allowed by the PLMN, and wherein the PLMN is comprised in a PLMN list, and the PLMN list is one or a combination of the following PLMN lists; a list of PLMNs supported by the mobility management network element or a subset of the PLMN list, a list of PLMNs equivalent to a PLMN supported by the mobility management network element or a subset of the PLMN list, a list of PLMNs equivalent to the PLMN serving the UE or a subset of the PLMN list;
a list of PLMNs that have a roaming or a cooperation agreement with a PLMN supported by the mobility management network element or a subset of the PLMN list;
a list of PLMNs that have a roaming or cooperation agreement with the PLMN serving the UE or a subset of the PLMN list,a list of PLMNs that belong to a same operator as a PLMN supported by the mobility management network element or a subset of the PLMN list, and a list of PLMNs that belong to a same operator as the PLMN serving the UE or a subset of the PLMN list; a memory storing a program; and a processor, configured to execute the program, the program comprising instructions for determining a target RAT for the UE according to the access control information. - View Dependent Claims (7, 8, 9, 10)

11. A mobility management network element, comprising:
-
a receiver, configured to acquire access control information of a user equipment (UE); and a transmitter, configured to send the access control information of the UE to an access network element, so that the access network element can determine a target radio access technology (RAT) for the UE according to the access control information, wherein the access control information comprises an identity of a public land mobile network (PLMN) and a RAT, wherein the access control information further comprises either information that the RAT is allowed by the PLMN or information that the RAT is not allowed by the PLMN, and wherein the PLMN is comprised in a PLMN list, and the PLMN list is one or a combination of the following PLMN lists; a list of PLMNs supported by the mobility management network element or a subset of the PLMN list, a list of PLMNs equivalent to a PLMN supported by the mobility management network element or a subset of the PLMN list, a list of PLMNs equivalent to the PLMN serving the UE or a subset of the PLMN list;
a list of PLMNs that have a roaming or a cooperation agreement with a PLMN supported by the mobility management network element or a subset of the PLMN list;
a list of PLMNs that have a roaming or cooperation agreement with the PLMN serving the UE or a subset of the PLMN list,a list of PLMNs that belong to a same operator as a PLMN supported by the mobility management network element or a subset of the PLMN list, and a list of PLMNs that belong to a same operator as the PLMN serving the UE or a subset of the PLMN list. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
