ETSI ETSI TS 136 442 V14.0.0 (2017-04)53GPP TS 36.442 version 14.0.0 Release 141 Scope The present document specifies the standards for signalling transport to be used across M2 and M3 interfaces. M2 interface is a logical interface between the eNB and the MCE. M3 inte
21、rface is a logical interface between the MCE and the MME. The present document describes how the M2-AP signalling messages are transported over M2, and how the M3-AP signalling messages are transported over M3. 2 References The following documents contain provisions which, through reference in this
22、text, constitute provisions of the present document. - References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific. - For a specific reference, subsequent revisions do not apply. - For a non-specific reference, the latest version applies.
23、In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document. 1 3GPP TR 21.905: “Vocabulary for 3GPP Specifications“. 2 IETF RFC 2460 (1998-12): “Internet Protoc

It is also considered as a reference point. 3.2 Abbreviations For the purposes of the present document, the abbreviations given in TR 21.905 1 and the following apply. An ab
