1 Scope
The present document specifies the E-UTRAN radio network layer signalling protocol for the M3 interface. The M3
Application Protocol (M3AP) supports the functions of M3 interface by signalling procedures defined in this document.
M3AP is developed in accordance to the general principles stated in TS 36.401 [2] and TS 36.300 [3].

3 Definitions, symbols and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in TR 21.905 [1] and the following apply. A
term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905 [1].
Elementary Procedure: M3AP consists of Elementary Procedures (EPs). An Elementary Procedure is a unit of
interaction between MCEs and the EPC. These Elementary Procedures are defined separately and are intended to be
used to build up complete sequences in a flexible manner. If the independence between some EPs is restricted, it is
described under the relevant EP description. Unless otherwise stated by the restrictions, the EPs may be invoked
independently of each other as stand alone procedures, which can be active in parallel. The usage of several M3AP EPs
together or together with EPs from other interfaces is specified in stage 2 specifications (e.g. TS 23.246 [6] and TS
36.300 [3]).
An EP consists of an initiating message and possibly a response message. Two kinds of EPs are used:
- Class 1: Elementary Procedures with response (success and/or failure).
- Class 2: Elementary Procedures without response.
For Class 1 EPs, the types of responses can be as follows:
Successful:
