1.16 to consider the regulatory and operational provisions for Maritime
Mobile Service Identities (MMSIs) for equipment other than shipborne
mobile equipment, taking into account Resolutions** 344 (Rev.WRC‑03)**
and **353 (WRC‑03)**

Introduction

Agenda item 1.16 considers the expansion of MMSIs to Search and Rescue
(SAR) aircraft and Aids to Navigation. This agenda item is comprised of
two issues:

1\) Management of the MMSIs numbering resource (Resolution 344
(Rev.WRC-03)); and

2\) MMSIs for equipment other than shipborne mobile equipment
(Resolution 353 (WRC‑03)).

With regard to Issue B, the CPM Report sets out two Methods and
associated revised regulatory provisions to satisfy this agenda item.

Taking the above into consideration, APT members support Method B in the
CPM Report and propose modifications to Article 19 of the Radio
Regulations as shown below.

Proposed texts are the same as the text in the CPM Report (5/1.16/4.2)

ARTICLE 19

Identification of stations

Section II -- Allocation of international series and assignment of call
signs

**MOD** ASP/41A16/303

**19.30** 2) As the need arises, ship stations and ship earth stations
to which the provisions of Chapter **IX** apply, and coast stations or
coast earth stations, or other non-shipborne stations capable of
commu­nicating with such ship stations, shall have assigned to them
maritime mobile service identities in accordance with Section VI of this
Article.

**Reasons:** Modified Recommendation ITU-R M.585-3 extends the
assignment of MMSIs to aircraft stations and aids to navigation.

**MOD** ASP/41A16/304

Section VI -- Maritime mobile service identities

**MOD** ASP/41A16/305

**19.99** § 39 When a station^5^ operating in the maritime mobile
service or the maritime mobile‑satellite service is required to use
maritime mobile service identities, the responsible administration shall
assign the identity to the station in accordance with the provisions
described in Recommendation ITU-R M.585-4; in so doing, it should take
into account any other relevant ITU‑R and ITU‑T Recommendations. In
accordance with No. **20.16**, administrations shall notify the Bureau
immediately when assigning maritime mobile service identities.

**Reasons:** Provision is modified to establish the incorporation by
reference of Recommendation ITU-R M.585-4.

**MOD** ASP/41A16/306

**19.100** § 40 1) Maritime mobile service identities are formed of a
series of nine digits which are transmitted over the radio path in order
to uniquely identify ship stations, ship earth stations, coast stations,
coast earth stations group calls, and other non-shipborne stations
operating in the maritime mobile service or the maritime
mobile-satellite service.

**Reasons:** Consequential change of the extension of the assignments of
MMSIs.

**MOD** ASP/41A16/307

**19.102** 3) The types of maritime mobile service identities shall be
as described in Recommendation ITU-R M.585-4.

**Reasons:** Provision indicates that the assignments of MMSIs are based
on Recommendation ITU‑R M.585.

**SUP** ASP/41A16/308

**19.103** to **19.107**

**Reasons:** Consequential change of the incorporation by reference of
Recommendation ITU-R M.585-4.

**MOD** ASP/41A16/309

**19.108A** § 41 The maritime identification digits M~1~I~2~D~3~ are an
integral part of the maritime mobile service identity and denote the
geographical area of the administration responsible for the station so
identified.     (WRC-07)

**Reasons:** Consequential change of the suppression of Nos. 19.102 to
19.106.

**MOD** ASP/41A16/310

***19.110*** C **--** Maritime mobile service identities

**Reasons:** Consequential change of the extension of the assignments of
MMSIs.

**MOD** ASP/41A16/311

**19.111** § 43 1) Administrations shall follow the provisions contained
in Recommendation ITU‑R M.585-4 concerning the assignment and use of
maritime mobile service identities.

**Reasons:** Consequential change of the incorporation by reference of
Recommendation ITU-R M.585-4.

**MOD** ASP/41A16/312

**19.112** 2) Administrations should: **Reasons:** Consequential change
of the incorporation by reference of Recommendation ITU-R M.585-4.
Provision is reflected in No. 19.111.

**(MOD)** ASP/41A16/313

**19.113** *a)* make optimum use of the possibilities of forming
identities from the single MID allocated to them;

**Reasons:** This is an editorial modification.

**(MOD)** ASP/41A16/314

**19.114** *b)* take particular care in assigning ship station
identities with six significant digits (i.e. having three-trailing-zero
identities), which should be assigned only to ship stations which can
reasonably be expected to require such an identity for automatic access
on a worldwide basis to public switched networks, in particular
for mobile-satellite systems accepted for use in the GMDSS on or before
1 February 2002, as long as those systems maintain the MMSI as part of
their numbering scheme.     (WRC-07)

**Reasons:** This is an editorial modification.

**SUP** ASP/41A16/315

**19.115** to **19.126**

**Reasons:** Similar contents of these provisions are described in
Recommendation ITU-R M.585-4.
