Cell Selection - PLMN Selection
i) PLMN from IMSI (Home PLMN)
ii) Last Registered PLMN(Recorded in EF_LOCI)
iii) PLMNs listed in EF_EHPLMN(Equivalent HPLMN)
iv) PLMNs listed in EF_HPLMNwAct(Home PLMN with Access Technology)
v) PLMNs listed in EF_PLMNwAct(PLMN with Access Technology, User Controlled PLMN selector with Access Technology)
vi) PLMNs listed in EF_OPLMNwAct(Operator Controlled PLMN with Access Technology)
The question is which of these PLMNs has highest priority for cell selection ? The answer is described in 3GPP 23.122 184.108.40.206.1.
