.sp 1P
.RT
.PP
In order to permit land mobile stations to roam, there is a need to transfer 
information, e.g.\ the mobile station roaming number between Public 
Land Mobile Networks\ (PLMNs). This transfer of information can be accomplished 
by the use of Transaction Capabilities\ (TC) and the SCCP of Signalling 
System\ No.\ 7.
.PP
When a land mobile station roams to a foreign PLMN, it registers with  a 
Visited Location Register
\ (VLR) within that PLMN. The only
information available to the VLR to address the mobile's Home Location
Register\ (HLR) is its International Mobile Station Identity\ (IMSI).
.PP
The purpose of this Recommendation therefore is to define the
structure of the mobile global title used in SCCP addressing to the public 
land mobile service, and to establish the relationship between the mobile 
global 
title and the international mobile station identity as defined in
Recommendation\ E.212.
.RT
.sp 2P
.LP
\fB2\fR 	\fBConsiderations\fR 
.sp 1P
.RT
.PP
The considerations which form the basis of the Mobile Global
Title\ (MGT) for the 
land mobile service
are as follows:
.RT
.PP
2.1
The MGT shall be derived from the 
international mobile
station identity
in a simplified manner.
.sp 9p
.RT
.PP
2.2
There could be a number of PLMNs in a country.
.PP
2.3
The MGT shall permit the identification of the country as well as the PLMN 
in which the 
mobile station
is registered.
.PP
2.4
The MGT should, as an option, permit the identification of the
home location register
\ (HLR) of the mobile station.
.PP
2.5
The length of the MGT should be minimized.
.PP
2.6
The MGT should enable the fixed network exchanges to utilize
existing routing information in order to identify the PLMN.
.PP
2.7
Recommendations E.163, E.164, E.165, E.212 and E.213 are
applicable.

3.1
	\fIStructure of the mobile global title\fR 
.sp 9p
.RT
.PP
The 
mobile global title
is of variable length and composed of decimal digits arranged in two specific 
parts. These specific parts are the E.164 and the E.212 part. 
.PP
The E.164 part is used to identify the country and the PLMN, or PLMN
and HLR, where the mobile station is registered. To accomplish this, the
E.164\ part comprises a Country Code\ (CC), as defined in Recommendation\ 
E.163, and a Network Code\ (NC) which can be the National Destination Code\ 
(NDC), as defined in Recommendation\ E.164, or the NDC and some additional 
E.164 
digits. The NC would identify the PLMN or HLR within the PLMN. The number of
E.164 digits required for identification may vary from network to network, 
and must be established by bilateral agreement. 
.PP
The E.212 part is used to identify the mobile station or mobile
station and HLR and is composed of the mobile station identification number 
as defined in Recommendation\ E.212.

Within the MGT the CC is derived directly from the MCC and the NC is derived

some initial digits of the MSIN. The MSIN is mapped directly into the MGT, 
up to its maximum length.

3.3
	\fILength of mobile global title\fR

.PP
The Mobile global title will be of variable length but with a
maximum of 15\ digits. Therefore, if necessary, the least significant digits 
of the MSIN will be omitted in order to conform with the maximum length 
of the 
MGT.

	\fIAnalysis of the mobile global title\fR

In order to permit fixed network nodes to utilize existing
resources, digit analysis in the originating country will conform to
Recommendation\ E.164. See also Recommendation\ E.165.

Further analysis beyond this requirement shall be by bilateral
agreement.

The analysis of the E.212 part of the mobile global title in the
destination fixed network is a national matter.

Within the numbering scheme, two digits Z\d1\uZ\d2\uhave been
allocated (see \(sc\(sc\ 4.3.1 and 4.4.1) to on\(hyboard identification. 
The purpose of these digits is to provide means for identifying different 
ship earth stations on the same ship, and different instruments, e.g.\ 
telephone instrument and a 
facsimile machine, connected to the same ship earth station.
.PP
Also, the present length of the \fIINMARSAT mobile international number\fR 
 | s limited 
to 12\ digits. After 1996 it will be possible to increase the number length 
to 15\ digits (see Recommendation\ E.165). 
.PP
It is considered that the above aspects can be met by careful
selection of the significance and values of Z\d1\uZ\d2\u.
.RT
.sp 1P
.LP
C.2
	\fIProposed structure\fR 
.sp 9p
.RT
.PP
As outlined earlier, it is necessary for Z\d1\uZ\d2\uto achieve two identification 
roles, i.e.\ station and instrument. It is considered that this can be 
accomplished by allocating Z\d1\uto multi\(hyship earth station 
identification and Z\d2\uto multi\(hyinstrument identification.
.PP
This structure would permit the uniform allocation of numbers to be
achieved and would allow the growth of ship earth stations to be independent
of the growth of instruments on any one ship earth station.
.PP
Further, in order to allow the future expansion of the numbering
length, it is proposed that Z\d1\ushould \fInever\fR be equal to\ 0 (zero) 
and the eighth digit of a 12\(hydigit ship earth station number should 
always be equal 
to\ 0 (zero) as long as these two number lengths coexist for the same value 
of T\ digit. 
.RT
.LP
	i.e.:
	T\ MID\ XXXZ\d1\uZ\d2\u	(9 digits with Z\d1\u\(!= 0)
.LP
	T\ MID\ XXX0XXZ\d1\uZ\d2\u	(12 digits)
.PP
The above approach would then allow the unambiguous identification of 9\(hydigit 
and 12\(hydigit ship earth station numbers on the same T\ digit. 
.PP
\fINote\fR \ \(em\ The above constraint on the eighth digit is not required 
in the future when only 12\ digit numbers exist in the INMARSAT system. 
.RT
.sp 1P

C.3
	\fIAllocation\fR 
.sp 9p
.RT
.PP
Therefore, from the above, a ship with one ship earth station and one instrument 
Z\d1\uZ\d2\uwould equal\ 10. If another instrument were added, 
then Z\d1\uZ\d2\uwould equal\ 11 for this instrument.
.PP
If a ship had two earth stations of the same standard and one
instrument attached to each, then the values of Z\d1\uZ\d2\uwould be\ 10 
for one station, and\ 20 for the second station. If a second instrument 
were added to 
the second station, then the value of Z\d1\uZ\d2\uwould be\ 21 for this
instrument.
.PP
Should it be necessary to allocate more than ten instruments per ship earth 
station, then another value of Z\d1\uwould be allocated to the earth 
station, e.g.\ for the tenth instrument Z\d1\uZ\d2\uwould be equal to\ 
19 and for the eleventh instrument 20 would be allocated or the next free 
value\ Z\d1\u.

each will have its own unique \fIINMARSAT mobile number\fR . 
.PP
Identification of different terminal equipment connected to a ship earth 
station is not possible in the INMARSAT Standard\(hyA system. However, 
provisions can be made for calls to specific service terminations on the 
ship, e.g.\ a facsimile equipment. If signals for providing such information 
are 
available within the signalling systems used between the switching centre of
call origin (i.e.\ the local national switching centre) and the coast earth
station, they should be automatically inserted by that switching centre. In
this case the numbering sequence would be as defined above, irrespective 
of the service termination on the ship. If some part of the connection 
does not have this capability, the required termination may be indicated 
by the following 
numbering sequence:
.LP

	International prefix
.LP

and Y\ =\ 2 is allocated to packet mode data transmission services using 
the protocol of 
Recommendation\ X.25. Of these, only Y\ =\ 1 will be available for selection by
telephone subscribers.
.PP
As other service termination requirements are identified by INMARSAT, the 
CCITT will make additional allocations. It should be noted that the 
digits\ 8Y cannot be used for discrimination between several terminals of the
same kind connected to a ship earth station. It should be further noted that
the digits\ 8Y should not be selected for ordinary telephone calls.

It is also possible to select specific services associated with
the call by use of other prefixes than 00, e.g.\ 34 (person\(hyto\(hyperson 
call), 35 (collect call), 36 (credit card call) and 37 (time and charges 
requested at 
end of call). The selection sequence will then be:

4.2.3
The ship earth station will permit the choice of a coast earth
station identity through which the call is to be routed. Convenient land\(hyline 
routings (e.g.\ use of the coast earth station nearest the destination 
country) could be encouraged by tariff considerations. 
.PP
4.2.4
In INMARSAT systems the shipboard user may also select a specified RPOA 
for routing the call, when a choice between several RPOAs is available 
at the coast earth station. This selection is provided by information which 
may 
not be part of the selection sequence. (For further study.)
.PP
4.2.5
In INMARSAT Standard\(hyB systems the user may chose among several
service options. If some service characteristics are user selectable, it 
should be possible to make the selection from the user terminal. Standardization

Some Administrations may wish to operate a system whereby
shipboard users insert after the operator prefix a country code (I\d1\u, 
I\d2\u, \d3\u). The insertion of the country code will allow the call to 
be routed to a relevant operator. If an Administration operating such a 
system receives an 
operator prefix without the optional digits, then the call must still be
connected to an appropriate operator. Similarly, if an Administration not
operating such a system receives an operator prefix followed by optional
digits, then the optional digits should be ignored and the call connected to
the operator denoted by the prefix alone.
