Section: 6.2.3 Service continuity requirements
Content: The 5G system shall enable packet loss to be minimized during inter- and/or intra- access technology changes for some or all connections associated with a UE. The 5G system shall minimize interruption time during inter- and/or intra- access technology mobility for some or all connections associated with a UE. NOTE: The interruption time includes all delays which have impact on service continuity. For applications that require the same IP address during the lifetime of the session, the 5G system shall enable maintaining the IP address assigned to a UE when moving across different cells and access technologies for connections associated with a UE. The 5G system shall enable minimizing impact to the user experience (e.g. minimization of interruption time) when changing the IP address and IP anchoring point for some or all connections associated with a UE. The 5G system shall support service continuity for a remote UE, when the remote UE changes from a direct network connection to an indirect network connection and vice-versa. The 5G system shall support service continuity for a remote UE, when the remote UE changes from one relay UE to another and both relay UEs use 3GPP access to the 5G core network. Satellite access related service continuity requirements are covered in clause 6.46.3.
