How UE selects PLMN in LTE Network

Hello,

If a UE fails to register most recent RPLMN or EPLMN, the UE attempts to select another PLMN. In automatic network selection mode, the UE selects a PLMN in the following preferential order:

EHPLMN with the highest priority if the EHPLMN list is present, or the HPLMN if the EHPLMN list is not present.
Each PLMN/radio technology combination in the User Controlled PLMN Selectoion with Access Technology data file in the USIM, in priority order.
Each PLMN/RAT combination in the Operator Controlled PLMN Selection with Access Technology data file in the USIM, in priority order.
Other high-quality PLMN/RAT combinations, in a random order. If the reference signal received power (RSRP) value of a cell in the PLMN/radio technology combination is greater than or equal to –110 dBm, the combination is considered a high quality PLMN/radio technology combination.
Other PLMN/radio technology combinations in order of decreasing signal quality.
When the UE finds a suitable cell in a PLMN following above procedure, the UE attempts to register on the PLMN. If the registration is successful, the UE camps on the suitable cell; otherwise, the UE tries the next PLMN. If the registration on none of the PLMNs is successful, the UE enters the Limited service state. If no PLMN is available, the UE could not obtain any services.

Thanks
