The MSISDN and international mobile subscriber identity (IMSI) are two important numbers used for identifying a mobile subscriber. The IMSI is stored in the SIM (the card inserted into the mobile phone), and uniquely identifies the mobile station, its home wireless network, and the home country of the home wireless network.
For telecom operator-provided cards, only the Group MSISDN number is known to multi-SIM subscribers. Member-SIM MSISDN is transparent to the subscriber. Messages sent to member SIM are delivered to the Group MSISDN. Multi-SIM allows switching among (up to) 12 stored numbers from the phone's main menu.
The primary MSISDN is the number used for making and receiving voice calls and SMS, but it is possible for a SIM to have other secondary MSISDNs associated with it for fax and data calls. Each MSISDN is also a unique key to the HLR record. The HLR data is stored for as long as a subscriber remains with the mobile phone operator.
The international mobile subscriber identity (IMSI; / ˈ ɪ m z iː /) is a number that uniquely identifies every user of a cellular network. [1] It is stored as a 64-bit field and is sent by the mobile device to the network.
The mobile identification number (MIN) or mobile subscription identification number (MSIN) refers to the 10-digit unique number that a wireless carrier uses to identify a mobile phone, which is the last part of the international mobile subscriber identity (IMSI).
The international call prefix or "+" is not counted as it encodes a value in a separate byte (TON/NPI - type of number / numbering plan identification). If the MSISDN is longer than 20 digits then additional digits are encoded into extension blocks (EF EXT1) each having a BCD-encoded field of 11 bytes. [6]
The VMSC will request the information needed for it to deliver the Short Message to its recipient by sending a Send_Info_for_MT_SMS message to the VLR. The VLR will then instigate a page request, or subscriber search, for the destination subscribers Mobile Subscriber ISDN Number (MSISDN), and return the result to the VMSC. Since a typical ...
The MAP SRI message contains the MSISDN number and with this MSISDN the HLR will obtain the IMSI. Because of past location updates, the HLR already knows the VLR that currently serves the subscriber. The HLR will send to the VLR a MAP PRN (Provide Roaming Number) message to obtain the MSRN of the roaming cell phone. Like that the HLR will be ...
