For a specific mobile terminal, it is necessary to maintain multiple PLMN lists of different types, and select the logged in network according to the corresponding PLMN priority. The article originates from the fallen fish- https://www.duoluodeyu.com/2297.html
Common PLMN classifications
RPLMN：Registered PLMN， The PLMN successfully logged in last time is stored in the terminal memory (it was decided at the TSG TP-21st meeting of 3GPP in 2003 to delete this parameter from the USIM card and save it in the terminal memory); The article originates from the fallen fish- https://www.duoluodeyu.com/2297.html
EPLMN：Equivalent PLMN， Equivalent PLMN, which is in the same position as the PLMN currently selected by the terminal; The article originates from the fallen fish- https://www.duoluodeyu.com/2297.html
EHPLMN：Equivalent Home PLMN， Equivalent home PLMNN, the home PLMN in the same position as the PLMN currently selected by the terminal; The article originates from the fallen fish- https://www.duoluodeyu.com/2297.html
HPLMN：Home PLMN， The MCC and MNC contained in the user's home PLMN and USIM card IMSI are consistent with the MCC and MNC on the HPLMN. For a user, there is only one PLMN to which he belongs; The article originates from the fallen fish- https://www.duoluodeyu.com/2297.html
UPLMN：User Controlled PLMN， The PLMN controlled by the user is stored in the USIM/SIM card; The article originates from the fallen fish- https://www.duoluodeyu.com/2297.html
OPLMN：Operator Controlled PLMN， PLMN controlled by the operator, stored in the USIM/SIM card; The article originates from the fallen fish- https://www.duoluodeyu.com/2297.html
VPLMN：Visited PLMN， Access PLMN. PLMN accessed for end users. The article originates from the fallen fish- https://www.duoluodeyu.com/2297.html
FPLMN：Forbidden PLMN， Disable PLMN; It is a PLMN whose access is prohibited. Generally, after the terminal attempts to access a PLMN and is denied, it will add it to this list. The article originates from the fallen fish- https://www.duoluodeyu.com/2297.html
