name: MSISDN
full_form: Mobile Subscriber Integrated Services Digital Network Number
context: An Additional MSISDN (A-MSISDN) is an MSISDN (see clause 3.3) that is assigned to a user with PS subscription in addition to the already assigned MSISDN(s). The structure of an A-MSISDN should follow the structure of an MSISDN number as defined in clause 3.3. The A-MSISDN shall be able to be used for TS11 (telephony) in the CS domain and shall be uniquely assigned per IMSI.
description: The Mobile Subscriber Integrated Services Digital Network Number (MSISDN) is a unique identifier assigned to a mobile subscriber, enabling them to receive and make calls, as well as access various services within the telecommunication network. An Additional MSISDN (A-MSISDN) is an extra MSISDN assigned to a user with a packet-switched (PS) subscription, in addition to their existing MSISDN(s), allowing for unique identification and service accessibility.
explanation: MSISDN is classified as an Identifier because it serves as a distinct code identifying mobile subscribers within the network, facilitating telecommunication services such as telephony in the circuit-switched (CS) domain. The assignment of A-MSISDN further emphasizes its role in uniquely identifying users and enabling service access.
