What is EPLMN (Equivalent PLMN)?

The Equivalent PLMN (E-PLMN) list permits a network to offer the UE with a list of PLMN identities. The E-PLMN can be signaled to the UE as segment of the GPRS attach procedures. The Equivalent PLMN List is only appropriate when the operating mode is set to Active Cell. The E-PLMN list is indicated as a single variable length GPIB command that determines the complete list.
