Abstract: Various communication systems may benefit from appropriate restriction on use. For example, certain wireless communication systems may benefit from radio-access-technology-specific access restrictions. A method can include registering a user equipment with a network element. The registering can include identifying user equipment capabilities. The method can also include receiving a response from the network element indicating restriction on use of at least one radio access technology.

Abstract: Systems, methods, apparatuses, and computer program products for dynamic subscription handling are provided. One method includes receiving, by a control node in a network, a request in which a user equipment requests to register with the network or requests to obtain a specific service for a certain access point name. The method may then include determining whether the user equipment is authorized to obtain services from the network or authorized to use the access point name. When it is determined that the user equipment is not authorized to obtain services from the network or not authorized to use the access point name, the method includes re-directing the user equipment to a subscription server, sending a response to the user equipment indicating that the request is rejected with re-direction, and triggering establishment of a packet data connectivity session for the user equipment.

Abstract: Various communication systems may benefit from improved voice call support. For example, it may be helpful for a user equipment in a first radio access technology that may not support voice calls to initiate a voice call with a second radio access technology. A method includes initiating a voice call between a user equipment to an entity in a second radio access technology cell. The user equipment is located in a first radio access technology cell. The method also includes registering the user equipment with the second radio access technology cell. In addition, the method includes conducting the voice call with the entity via the second radio access technology cell.

Abstract: Methods and apparatus, including computer program products, are provided for controlling emergency calling. In some example embodiments, there may be provided a method that includes receiving, at a user equipment, an indication for controlling whether the user equipment makes an emergency call over a fifth generation radio access technology or over another radio access technology as a fallback; and making, by the user equipment, the emergency call based on the received indication. Related systems, methods, and articles of manufacture are also described.

Abstract: Systems, methods, apparatuses, and computer program products for providing IMS level awareness of high latency device are provided. One method, when a UE attaches to EPC, receiving, at a network node, an indication that the UE is a high latency device. The method may also include assigning, to the UE, an IP address selected from a special IP address range that is designated specifically for high latency devices. When the UE performs IMS registration, the method may include determining that the UE is a high latency UE based on the UE's IP address provided with the IMS registration request and assigned during the EPC attach procedure.

Abstract: There are provided measures for enabling/realizing an inactive communication mode, namely an inactive mode for the operation of terminal equipment and network equipment in a communication system. Such measures exemplarily comprise operation in a connected mode, in which a data plane connection and a control plane connection are established between a terminal equipment and a network equipment, transition from the connected mode to an inactive mode upon data plane inactivity, and operation in the inactive mode, in which the data plane connection is released and the control plane connection is maintained between the terminal equipment and the network equipment.

Abstract: Determination of status of network nodes may be useful in various communication systems. For example, functional status exchange between network nodes, failure detection, and system functionality recovery may be applied in mobile and/or data communication networks. A method can include detecting, by a device, status of an application layer of a node. The method can also include informing, in a message, at least one other node of the status of the application layer of the node.

Abstract: Systems, methods, apparatuses, and computer program products for interworking between bearer-less networks and bearer-based networks are provided. One method includes receiving, by a network entity in a bearer-less network, a context request to obtain user equipment context information for a user equipment moving from the bearer-less network to a bearer-based network. The method may further include providing a context response comprising the context information to a network entity in the bearer-based network, the context information used to establish bearers for the user equipment to obtain internet protocol (IP) based services.
