name: CCIF
full_form: Connectivity Credentials Issuing Function
context: CCIF is responsible for the generation of credentials required for initial network connectivity as described in clause 5.1.3.3.2.1. This function is required where unauthenticated connectivity may not be available to deployed M2MEs. This function could be provided by a central organisation or the M2MES. CCIF supports the following functions: - Issuing initial network access credentials, e.g. preliminary IMSI numbers and preliminary keys, for each M2ME. NOTE 1: For examples of preliminary credentials see annex B. NOTE 2: Alternatives such as PCID and synthetic credentials could be possible. - Helping the M2MES to configure the M2ME with the above credentials. Modes of such configuration may include: - CCIF generates credentials and sends to M2MES to embed during manufacture time; or - M2MES generates and embeds them and sends them to CCIF afterwards; or - M2MES generates and embeds them and they are communicated to CCIF via the M2M subscriber
description: The Connectivity Credentials Issuing Function (CCIF) is a network function responsible for generating credentials required for initial network connectivity, such as preliminary IMSI numbers and keys. It supports issuing these credentials to Machine-Type Communications (M2MEs) and helps configure the M2ME with these credentials.
explanation: The context explicitly describes CCIF's role in managing network access credentials and configuring M2MEs, which aligns with the responsibilities of a Network Function within the telecommunications infrastructure.
