Management Guidelines and Procedures

1.0 PURPOSE AND SCOPE

This document contains the guidelines and procedures for the assignment and use of International Mobile Subscriber Identities (IMSIs) in the United States with consideration given

to other North American Numbering Plan (NANP) countries In certain circumstances! theseguidelines ma" also appl" to Territories of the United States

## The IMSI was created and formatted to provide the uni$ue internationalidentification of mobile terminals and mobile users and to enable these terminals andusers to roam among public networ%s which offer public mobilit" services

#& These assignment guidelines pertain! in one section or another! to all segments of the IMSI The IMSI Administrator (IMSI'A) participates in the management of allsegments of the IMSI! but directl" administers onl" the ome Networ% Identit" (NI)segment NIs are assignable to operators of public networ%s offering public mobilit"services with international roaming capabilities The NI uni$uel" identifies the home

networ% of a public mobilit" service subscriber and contains the Mobile ountr" ode(M) and the Mobile Networ% ode (MN) The remaining segment of the IMSI! theMobile Station Identification Number (MSIN)! is directl" administered b" the networ% operator to which the NI is assigned

#* These guidelines were developed b" the consensus of representatives of entitieswithin the telecommunications sector of the United States This consensus was achievedduring meetings of the IMSI Management +orum (IM+)! the open industr" forumchartered to manage and oversee the administration of IMSIs (See the document IMSI Management Guidelines and Procedures appended to this document as a non'integralAppendi,)

#- These guidelines appl" throughout the United States! e,cluding those UnitedStates Territories assigned their own uni$ue Ms! and do not supersede the regulations! procedures or re$uirements of the + or an" other appropriate legal or regulator"authorit"

#. These guidelines are based on the content of International TelecommunicationsUnion / Telecommunications0 (ITU'T) 1ecommendation 2&! The International Identification Plan For Mobile Terminals and Mobile Users This 1ecommendation wasrevised in #334 The content of this document is in conformance with that iteration of the1ecommendation

$Management Guidelines and Procedures

*. The IMSI format in the United States is a fi,ed #.'digit length '' the ma,imumallowable b" 1ecommendation 2& 2ach IMSI contains an M! an MN! and anMSIN The M and MN combine to form the US'defined NI! which is the segmentof the IMSI directl" administered b" the IMSI'A MSINs are administered directl" b" thenetwor% operator to which the NI is assigned

*; The function of the M is to identif" the domiciliar" countr" of a mobileterminal5user @ through ?*#;@

* The function of the MN is to identif" the home networ%! within the countr"associated with the M! of the visiting mobile terminal5user The visited networ% usesthe M'MN combination to identif" and $uer" the home networ% of the visitingmobile terminal5user that is re$uesting service

MNs in the United States are three digits in length and in the format ===! where =

e$uals an" of the decimal digits >'3 The *'digit ma,imum is necessar" so that! whencombined with the *'digit M! the visited networ% need not anal"6e more than ; digitsto determine the home networ% of the visiting mobile terminal5user! another 1ecommendation 2& re$uirement This format provides a mathematical potential of one thousand MNs (>>>'333) for each M onse$uentl"! a mathematical potentialof seven thousand public networ%s can be served b" the seven Ms allocated to theUnited States

MSINs in the United States are nine digits in length and in the format =========!

where = e$uals an" of the decimal digits >'3 1ecommendation 2& limits IMSI lengthto a fifteen'digit ma,imum Since the United States IMSI format includes a si,'digitNI! a nine'digit MSIN is the ma,imum allowable The nine'digit format provides one billion MSINs per MN or networ%! if no other function than mobile terminal5user identification is embedded in the MSIN

"Management Guidelines and Procedures

*3 The NI contains the M followed b" the MN and is a fi,ed ;'digit length inthe United States The NI is re$uired in a countr" with multiple allocated Ms because anal"sis of both the M and the MN is re$uired to uni$uel" identif" the homenetwor% since MNs will be duplicated within the multiple Ms allocated to the

countr" The NI is not specified in 1ecommendation 2& It has been created anddefined in the United States to address the lac% of MN uni$ueness inherent in a multipleM environment

*#> Test NIs are available for use b" the industr" The test NIs are intended for use b" industr" entities to perform internal testing These NIs do not identif" an" particular networ% Test NIs are not for e,clusive use b" an" industr" entit" and itshould be e,pected that the same NIs ma" be in use b" other entities simultaneousl"

*## All current NI assignments (including test NIs) are available at the IMSI'A

website wwwimsiadmincom

4.0 ASSUMPTIONS AND CONSTRAINTS

These guidelines are based on the following assumptions and constraints8

-# These guidelines and procedures should provide the greatest latitude to those providing public mobilit" services! while permitting the effective and efficientmanagement of a finite resource

-& Although the $uantit" of IMSIs available within the seven Ms currentl"allocated to the United States is substantial! the demand for NIs ma"! at some time in

the future! e,ceed the capacit" of the seven Ms initiall" assigned to the United StatesPlanning for M e,haust and obtaining additional M resources are discussed inSection ##

-* The guidelines and procedures for IMSI assignment in the United States! as setforth in this document! remain in effect until there is either industr" consensus or regulator" polic" direction to change them

&Management Guidelines and Procedures

-- These guidelines do not describe the method b" which IMSIs are transmittedacross and processed b" public networ%s Networ% interwor%ing arrangements arecontained in other standards! documents! or business agreements

-. There are authori6ed NI application and maintenance fees 2ach applicationmust have an accompan"ing NI application fee pa"ment or the application will bereturned The NI application fee funds the NI Administration function Additionall"!each NI assignee will be separatel" assessed an annual NI maintenance fee

5.0 ASSIGNMENT PRINCIPLES

The assignment principles defined below allow public networ% operators the greatest possiblelatitude in providing public mobilit" service and the users of these services the widest possibleroaming capabilities

.# NIs are to be assigned and used onl" b" public networ%s offering publicmobilit" services (Section #&)

.& Upon application! the IMSI'A will assign one NI for each valid networ% operator Nothing shall preclude a networ% operator! however! from aggregating multipleor merged networ%s5licenses within a single NI

.* The ;'digit NI! as part of the #.'digit IMSI! is to be assigned so as to uni$uel"identif" the home networ% of the terminal5user

.- MSINs are assigned b" networ% operators to their subscribed mobile

terminals5users An IMSI is uni$ue to a single mobile terminal5user! but a mobileterminal5user ma" have multiple IMSIs

.. IMSIs and NIs shall be assigned to permit the most effective and efficient use of a finite resource in order to ma,imi6e the e,isting allocated resource inventor" and todefer! as long as practical! the need to re$uest additional M resources

.; IMSIs are a public resource The assignment of an" portion of an IMSI (ie! NI!MSIN) does not impl" ownership of the resource b" either the entit" to which it isassigned or b" the entit" performing the administrative function

. Should an assignee transfer control of the M1S license or a portion of its

serving area under an e,isting license! then the use of the assigned NI is transferable tothe new license owner

.4 The IMSI'A will8

9 Assign NIs in a fair! timel"! and impartial manner to an" applicant that meets thecriteria for assignment (Section ;)
