Section: 6.38.2.3 Operation without 5G core network connectivity
Content: The 5G system shall allow PIN Elements to communicate when there is no connectivity between a PIN Element with Gateway Capability and a 5G network. For a Public Safety PIN licensed spectrum may be used for PIN direct communications otherwise unlicensed spectrum shall be used. When a CPN has lost connectivity with the 5G network, the 5G system shall provide an operator-controlled mechanism to enable: - in the default configuration, or under certain conditions configured by the operator, the PRAS radio interface shall be deactivated; and - under certain other conditions configured by the operator, the CPN shall continue existing intra-CPN communication, as long as no interaction with the 5G network is needed (e.g. refreshing security keys). NOTE 1: The requirement above relates to intra-CPN operations and is subject to operator policy and control, under certain situations. NOTE 2: Setting up new intra-CPN or intra-PIN communication sessions without connection to the 5G network is only possible with non-3GPP provided credentials.
