Abstract:
Provided are a method and apparatus for selecting a Public Land Mobile Network (PLMN). A method for providing a PLMN list in a Mobility Management Entity (MME) may include: receiving a request from a user equipment (UE); determining whether the UE prefers Voice over Long Term Evolution (VoLTE) according to the request; and sending, when the UE prefers VoLTE, a variant equivalent PLMN list that contains, for each PLMN, information indicating whether VoLTE is supported by the PLMN or a VoLTE-support PLMN list that contains only PLMNs supporting VoLTE. Hence, the UE having a preference for VoLTE may select an equivalent PLMN supporting VoLTE in an effective manner.
