Abstract: A method of managing an Evolved Packet System (EPS) fallback procedure in a 5GS network. The method comprises making available to the Access Mobility Function (AMF), a configuration parameter per Public Land Mobile Network (PLMN) indicating if early or late PCRF/PCF interaction with the IMS is used. Then, upon receipt by the network of a 5GS network registration request from a UE, the home PLMN of the UE is identified as is the configuration parameter for that PLMN. The identified parameter is then used to determine for the UE whether or not EPS fallback is available to the UE, and an indication of the determination is sent to the UE.

Abstract: A communication device comprises a container environment with a plurality of containers each having one or more applications and each being connectable to a network slice, and a container manager configured to control communication between the applications and the network slices, wherein the container manager prohibits communication between a first application in a first container and a second application in a second container.

Abstract: When a user equipment is roaming in a visited network, mid-call handover from VoWiFi to VoLTE is controlled by policies enforced in the user equipment and the home network. An inter-operator policy and a subscription policy are stored in the home network and a user equipment policy is stored in the user equipment. The roaming user equipment registers in a visited network. Later, when mid-call handover to VoLTE on the visited network is desired, and also permitted by its user equipment policy, the user equipment sends a request containing a call-specific identifier which the responsible network entity in the home network compares with the registered handover parameter having regard to the inter-operator and subscription policies. If compliance with the policies is found, then the mid-call handover is proceeded with.
