Example missing

[edit]

At the least, this article needs an example of a number. --DKEdwards 23:57, 16 November 2006 (UTC)[reply]

The example looks wrong to me: 880 is not India, but Bangladesh and 18 is the operator code of Robi mobile. I changed the example, which before said 880 is India and 18 is Trivandrum.--134.21.208.185 (talk) 11:05, 10 January 2017 (UTC)[reply]

Poor language

[edit]

The language in this article is poor. For example, 'The MSISDN phone starting from the country code.' is not a sentence. --213.78.152.15 23:22, 15 February 2007 (UTC)[reply]

Poor Language

[edit]

The languge that artical is poor. For Example,""The MSISDN phone strting from countary code after that NPA(National planning Area) & after that SN(Subscriber number) 380 561234567, 12 Fec 2013(UTC) — Preceding unsigned comment added by Rahul.sharma9197 (talk • contribs)


Difference IMSI-MSISDN

[edit]

It would be interesting if someone could clarify the difference between IMSI and MSISDN. 82.182.97.112 18:53, 8 April 2007 (UTC)[reply]

IMSI vs MSISDN

[edit]

IMSI - International Mobile Subscriber Identity

MSISDN - Mobile Directory Number

Both are two different numbers. One is used to identify a subscriber by operator. Other is used to route the call. A subscriber becomes customer of an operator by buying the SIM card of the operator. At this point the subscriber is allocated an IMSI and an MSISDN. IMSI is used to identify a subscriber by the operator. But MSISDN is the number which is used for dialing. So when you call your friend/a mobile, you call the MSISDN number of the mobile, not the IMSI.

For Eg: Consider 2 subscriber's A & B. And assume the values given below;

IMSI (A) : 987123111111111

IMSI (B) : 987124111111111

MSISDN (A) : 9448012121

MSISDN (B) : 9448121212

So when A would like to call B, A dials the MSISDN number of B, i.e, 9448121212. And same is true for vice-versa.

Now coming to need of IMSI, when a mobile is switched on, it needs to identify and authenticate the subscriber with the network. Only then the mobile will be able to use the network services. So to identify the user in this scenario, the IMSI of the subscriber is used. In fact the IMSI is burned in the SIM card, which will be used while authenticating with network. MSISDN will not be stored in the SIM.

A couple of important things were left out of that description. There are three identities IMEI, IMSI and MSISDN. The IMEI is the mobile phone's identity which is burned into the phone. The IMSI is the identity of the SIM card. And MSISDN is the phone number. You can change the phone number of the phone without changing its IMSI (the sim card). You can keep the same phone number (MSISDN), change phones (the IMEI) and just move the SIM card (IMSI). By separating the three identities, it makes it easy for subscribers to easily upgrade phones without having to change phone numbers or accounting information.

Thank you for these good clarifications. Related to this and the points made above about the language of the article, I made a change, the article says: "Simply put, it is the telephone number of the SIM card in a mobile/cellular phone" - "of" points to a situation where the phone number would be somehow a part of the SIM card. It is not, as is noted in the comments. Thus, I changed it to "to", implying that the MSISDN points to a SIM card, instead of being an entity of the SIM card. The MSISDN is in a master table accessed by all operators when calls related to that number are routed from and to the recipient. It is lying next to the current IMSI associated with that number ...the IMSI (SIM card) can change as numbers are rotated within or between operators. 192.100.120.41 (talk) 07:20, 25 August 2011 (UTC)[reply]

Requested move

[edit]
The following discussion is an archived discussion of the proposal. Please do not modify it. Subsequent comments should be made in a new section on the talk page. No further edits should be made to this section.

The result of the proposal was Move. Apparently, the confusion is present both in real world and among editors; it's best to leave it at abbreviated title and elaborate on variety of interpretations in the article.

Mobile Station Integrated Services Digital Network → MSISDN — Since the interpretation of the abbreviation isn't unique, it would be best to keep the abbreviation as the name of the page —Buzztr 21:51, 20 September 2007 (UTC)[reply]

Survey

[edit]
Feel free to state your position on the renaming proposal by beginning a new line in this section with *'''Support''' or *'''Oppose''', then sign your comment with ~~~~. Since polling is not a substitute for discussion, please explain your reasons, taking into account Wikipedia's naming conventions.
  • Support

None of the organizations 3GPP, ITU, OMA or GSMA uses the interpretation of the abbreviation that this page title suggests. Since there is no single interpretation, IMHO it would be best to use the abbreviation MSISDN as name for the page although the Wikipedia Naming Conventions prefer spelled-out phrases to abbreviations. However, if no consensus can be reached on this, the second best name would be Mobile Subscriber Integrated Services Digital Network Number which is the full printout of the abbreviation today used by the most organizations.

Discussion

[edit]
Any additional comments:
  • Comment. Make MSISDN a dab page, or modify the article, if moved, to open with the various names including:
    • Mobile Service Integrated Services Digital Network
    • Mobile Station Integrated Services Digital Network
    • Mobile Subscriber ISDN Number
    • Mobile Station International Subscriber Directory Number
    • Mobile Station ISDN Number
    Vegaswikian 19:49, 24 September 2007 (UTC)[reply]
  • Comment. I am a little ambivalent to add all various names since some of them has no support of any standardization body that I know of. Adding a name in the Wikipedia, could encourage the use of it although we have no reference to its correctness. I would be happy to support the addition of all names that we can find a standardization organization that actively use it. At this time, that would limit the names to:
    • Mobile Subscriber ISDN Number
    • Mobile Station International ISDN Number
    • Mobile Subscriber International ISDN Number

If anyone know of any other names (with reference), it would be greatly appreciated.

MSISDN structure

[edit]

The structure of the MSISDN is standardized as part of ETSI specification 3GPP CN TS 23.003 "Numbering, addressing and identification" as "MS international ISDN number" http://www.arib.or.jp/IMT-2000/V650Mar08/5_Appendix/R99/23/23003-3f0.pdf Refer to Figure 2.

Question..

[edit]

1. What happens when a single MSISDN (93700802602) is mapped to two or more IMSI (SIM identifier) ? If a subscriber calls this MSISDN (93700802602) will the call go to both the IMSI's ? 

                                                                                                                                 Kumar.saurabh90 (talk) 09:41, 28 December 2011 (UTC)[reply]
