Element Manager: Provides a package of end-user functions for management of a set of closely related types of network elements. These functions can be divided into two main categories.
Element Management Functions:
Set of functions for management of network elements on an individual basis. These are basically the same functions as supported by the corresponding local terminals.
Elementary File (EF):

Elementary procedure (EP):
The RANAP, RNSAP, NBAP, S1AP, X2AP, PCAP, HNBAP, LPPa, RNA, RUA, RETAP and TMAAP protocols consist of elementary procedures (EPs).
An EP consists of an initiating message and possibly a response message.
Three kinds of EP are used:
Class 1: Elementary Procedures with response (success or failure).
Class 2: Elementary Procedures without response.
Class 3: Elementary Procedures with possibility of multiple responses (RANAP only).
For Class 1 EPs, the types of responses can be as follows:
A signalling message explicitly indicates that the elementary procedure has been successfully completed with the receipt of the response.
A signalling message explicitly indicates that the EP failed.
Class 2 EPs are considered always successful.
Class 3 EPs have one or several response messages reporting both successful and unsuccessful outcome of the requests, and temporary status information about the requests. This type of EP only terminates through response(s) or EP timer expiry.
An End-User is an entity (typically a user), associated with one or multiple subscriptions through identities (e.g. IMSIs, MSISDNs, IMPIs, IMPUs and application-specific identities). In the 3GPP system an End-User is characterised by an End-User Identity.

This list is stored on the USIM and is known as the EHPLMN list. The EHPLMN list may also contain the HPLMN code derived from the IMSI. If the HPLMN code derived from the IMSI is not present in the EHPLMN list then it shall be treated as a Visited PLMN for PLMN selection purposes.
