Abstract
Some example embodiments disclose methods for selecting registered public land mobile network (RPLMN) radio access technology (RAT) modes in wireless communication devices. The method as disclosed herein includes determining location information of the wireless communication device; validating the location information; deriving a RPLMN from the validated location information when the validating is successful; storing a RPLMN access technology (AccTech) based on the derived RPLMN; and selecting a RAT mode using the stored RPLMN AccTech.
Claims18
A method performed by a wireless communication device for selecting a radio access technology (RAT) mode, the method comprising:
- determining location information of the wireless communication device;
- identifying a public land mobile network (PLMN) based on the location information;
- obtaining a subscriber identity module (SIM) preferred list from a SIM based on a current operating mode;
- when the identified PLMN is present in the obtained SIM preferred list, identifying one or more first access technology (AccTech) recorded in the SIM preferred list corresponding to the identified PLMN;
- when the identified PLMN is absent in the SIM preferred list, identifying one or more second AccTech supported by the current operating mode;
- and
- determining the RAT mode based on the one or more first AccTech or the one or more second AccTech.
A wireless communication device for selecting a radio access technology (RAT) mode, the wireless communication device comprising:
- a memory;
- and
- at least one processor configured to
- determine location information of the wireless communication device,
- identify a public land mobile network (PLMN) based on the location information,
- obtain a subscriber identity module (SIM) preferred list from a SIM based on a current operating mode,
- when the identified PLMN is present in the obtained SIM preferred list, identifying one or more first access technology (AccTech) recorded in the SIM preferred list corresponding to the identified PLMN,
- when the identified PLMN is absent in the SIM preferred list, identifying one or more second AccTech supported by the current operating mode, and
- determining the RAT mode based on the one or more first AccTech or the one or more second AccTech.
