The method comprises receiving, from the wireless device and/or from a second core network node of the first network, control signalling indicating that the wireless device requires that a tunnel between the wireless device and the second network and via a gateway of the first network is maintained. The method comprises controlling a radio access network node and/or the gateway based on the control signalling and a capability of the first core network node of the first network to maintain the tunnel.

Methods for enhancing service continuity between a wireless device and a second network, related core network nodes, and related wireless devices

A method of managing a paging message for a user Equipment (UE) in a wireless communication network includes transmitting the paging message to the UE in the wireless communication network, receiving a wait indication from the UE, and delaying a retransmission of the paging message to the UE responsive to receiving a wait indication from the UE. A method of operating a UE in a wireless communication network includes receiving a paging message from a network node, and, responsive to receiving the paging message, transmitting a wait indication to the network node indicating a delay in transmission of a response to the paging message.

Systems, methods, and computer program products for providing a wait indication for a delayed paging operation

A method of operating a wireless communication device () includes transmitting (), to a first communication network (-), a request () for one or more communication gaps () in a communication along a data connection () associated with a first identity () of the wireless communication device () and monitoring (), in accordance with a timing of the one or more communication gaps (), for one or more paging signals () from a second communication network (-), the one or more paging signals () being associated with a second identity () of the wireless communication device ().

Communication gaps for paging of multi-subscriber identity wireless communication devices

A method of operating a node of a communications network is provided. The node is configured to support at least one data link. The at least one data link is between the communications network and a UE. The method includes providing registration data to an exposure node of the communications network. The registration data is for a reporting service on DSI of the at least one data link. The method also includes, upon receiving a subscription request for a subscription to the reporting service, establishing the subscription to the reporting service between the node and an external application node. The external application node is associated with the subscription request. The method furthermore includes providing the DSI in accordance with the subscription to the external application node.

Reporting service for dynamic status information on a data link

An infrastructure equipment that transmits a radio network identifier to a communications device for identifying the communications device when allocating communications resources of the wireless access interface for transmitting downlink data to the communications device. After the communications device has entered an inactive connected state, the infrastructure equipment transmits control signals including the radio network identifier for allocating communications resources of the wireless access interface for the communications device to receive downlink data, determine whether the communications device is still within a radio coverage area of the infrastructure equipment, and if the communications device has left the coverage area, transmit an indication to the one or more other infrastructure equipment via the inter-connecting interface to trigger a process for transmitting downlink data to the communications device from the one or more other infrastructure equipment.

Infrastructure equipment for determining whether a communications device is within a radio coverage area

Schemes for supporting device-to-device, D2D, communications between terminal devices in a wireless telecommunication system. A network entity, e.g. a base station, establishes a set pool of radio resources to be reserved for use for D2D communications and communicates an indication of these resources to terminal devices. On an ongoing basis the network entity monitors the extent to which the set of radio resources reserved for D2D communications is being used, for example based on feedback received from terminal devices or its own measurements. If it is determined the set of radio resources reserved for D2D communications is being under-utilized or over-utilized, the network entity may establish an updated set of radio resources to be used for D2D communications, and communicate this to the terminal devices. Thus a mechanism is provided for dynamically adjusting the size of a set of resources available for D2D communications in response to changing resource utilization.
