  • registration refers to a process where a device registers into a communication network. Registration involves that the device selects a communication network for use, and may comprise that the device indicates to the communication network an identity of the device, an identification of its subscription to the communication network, and data allowing the communication network to contact the device for communication purposes. This data may be a network address or a geographical position such as a location area, a roaming area, or a tracking area.
  • Such a device may be a mobile phone, a tablet, an Internet of Things (loT) device or a computer with a wireless network card.
  • Such device may be also referred as a user equipment.

It can be a telephone type of device, for example a telephone or a SIP phone, cellular telephone, a mobile station, cordless phone, or a personal digital assistant type of device like laptop, notebook, notepad equipped with a wireless data connection.

  • Subscriber Identity associated with a subscription belonging to a subscriber using the UE.

  • shared device refers to a device that has no permanently allocated user, i.e. the user of the device may change over time.
  • a shared device could be in use by a particular user/subscriber, or be unallocated, so free for seizure.
  • Such a shared device would be available for use among subscribers/users of a communication network.
  • Shared devices may be grouped into a pool, such that if a user/subscriber needs such a device, he/she may simply pick any device from the pool for use, and returns it to the pool after the usage has ended.
  • Such pool of shared devices may also comprise devices of different capabilities, such that a user/subscriber could pick a device that matches its current needs.
  • the shared device may be a beamer in a meeting room and the current presenter in the meeting room could seize the beamer for his presentation.
  • Another example could be a rental car, where the communication unit within the car is taken into use by the tenant during the rental period, and the use ends when the car is returned.
  • Yet another example may be the power meter at home, that is taken into use by a chosen energy provider. When the energy provider is changed, the power meter would be released and taken over by the next chosen energy provider.

  • An eSIM is a physical SIM which is permanently placed (embedded) in a device.
  • An eSIM is integral to the device, i.e. an eSIM cannot be removed and neither re-programmed or moved.
  • 'reprogrammable' SIM This refers to a physical SIM hardware that can be programed with different subscription profiles. So a soft-SIM may also refer to an image of a subscription that is moved into the physical SIM hardware after reception.
  • a soft-SIM on a target device may be held in the generic memory or in a reprogrammable SIM. So, the term soft-SIM may refer to the actual SIM related functions (e.g. specific software or algorithms) and data (related to a particular subscription in the communication network) without being related to any specific hardware or implementation.

If the subscriber is a human being, he/she can at the same time also be the user of a device accessing the communication network. However, the subscriber may also be a parent and the user may be the child of the parent. In this case the user and the subscriber are different roles.

  • authentication may refer to an act of confirming the authenticity of an entity. This might involve confirming the identity of an entity, so ensuring that an entity actually is what it claims to be. Authentication involves verifying the validity of identifications.
  • IKE RFID (RFC2409) and IKEv2 (RFC4306) are examples of key management protocols also used to authenticate a remote peer.
  • the term "authorization” may refer to the process of granting access rights to data, resources, or an entity.
  • the peer In a first step the peer is authenticated, so it is confirmed that the peer is what it claims to be. In a second step it can then be verified whether the peer is allowed to access certain data, resources, or an entity.
  • Authorization can be based on data administered in a node by the operator of the communication network.
  • Equipment identity or device identity refers to an identifier being unique in the sense that the same identifier will not exist a second time. Even an equipment of the same type would show a different identifier.
  • the identifier itself may consist of numbers and/or letters.
  • the identifier may be sub-structured and the different substructures can be separated for example by hyphens, dots, or spaces. It may be constructed of a serial number combined with a product and manufacturer identifier.
