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.
Claims18
A method, comprising:
- receiving, by an access network element from a mobility management network element, access control information of a user equipment (UE) in a handover restriction list, wherein the access control information comprises:
- a list of public land mobile networks (PLMNs) including identities of the PLMNs;
- and
- information corresponding to one or more PLMNs in the list of PLMNs, wherein the information corresponding to the one or more PLMNs indicates at least one radio access type (RAT) allowed or not allowed for the UE to use to access a PLMN of the one or more PLMNs;
- and
- determining, by the access network element according to the access control information, a target PLMN from the list of PLMNs and a target RAT for the UE to access the target PLMN using the target RAT, wherein the target RAT is allowed for the UE to use to access the target PLMN.
An apparatus comprising:
- a transceiver;
- a non-transitory memory storage comprising instructions;
- and
- one or more processors in communication with the transceiver and the memory storage, wherein the one or more processors execute the instructions to:
- control the transceiver to receive, from a mobility management network element, access control information of a user equipment (UE) in a handover restriction list, wherein the access control information comprises:
- a list of public land mobile networks (PLMNs) including identities of the PLMNs;
- and
- information corresponding to one or more PLMNs in the list of PLMNs, wherein the information corresponding to the one or more PLMNs indicates at least one radio access type (RAT) allowed or not allowed for the UE to use to access a PLMN of the one or more PLMNs;
- and
- determine, according to the access control information, a target PLMN from the list of PLMNs and a target RAT for the UE to access the target PLMN using the target RAT, wherein the target RAT is allowed for the UE to use to access the target PLMN.
A non-transitory computer-readable medium storing computer instructions, that when executed by one or more processors, cause the one or more processors to perform the steps of:
- receiving, from a mobility management network element, access control information of a user equipment (UE) in a handover restriction list, wherein the access control information comprises:
- a list of public land mobile networks (PLMNs) including identities of the PLMNs;
- and
- information corresponding to one or more PLMNs in the list of PLMNs, wherein the information corresponding to the one or more PLMNs indicates at least one radio access type (RAT) allowed or not allowed for the UE to use to access a PLMN of the one or more PLMNs;
- and
- determining, according to the access control information, a target PLMN from the list of PLMNs and a target RAT for the UE to access the target PLMN using the target RAT, wherein the target RAT is allowed for the UE to use to access the target PLMN.
