The embodiments herein relate to a method performed by a mobility node for handling a UE which has moved from an old to a new location. The mobility node retrieves UE context from a database. The mobility node determines whether there is a change of mobility node and first gateway at the new location. When there is a change of the first gateway, the mobility node initiates setup of a tunnel between a second gateway and a new first gateway. When there is a change of the mobility node, the mobility node provides a subscriber server with UE context for a new mobility node at the new location. The mobility node transmits updated UE context to the database.

A new network function is constituted and arranged in response to a request.

A base station device transmits a shared network identifier that is commonly used. Upon receipt of the shared network identifier, the communication device issues a connection request using own connection destination information. A server acquires and supplies a unique network identifier corresponding to the connection destination information associated with the connection request. The network configuration apparatus constitutes and arranges a network function on the basis of the unique network identifier that has been supplied.

A method performed by an E2 node is provided. The method includes transmitting an E2 setup request message to a radio access network (RAN) intelligent controller (RIC), and receiving an E2 setup response message from the RIC, wherein the E2 setup request message includes an information element (IE) related to an RIC service update request message, and wherein the E2 setup response message includes an IE related to an RIC service update acknowledgement message.

The present disclosure aims to provide a core node capable of appropriately allocating a radio resource of a RAN Slice allocated for a specific service to a radio terminal that uses this specific service. A core node according to the present disclosure includes: a determination unit configured to determine a radio resource to be allocated in accordance with a service provided for a radio terminal; and a communication unit configured to transmit resource identification information indicating the radio resource determined in the determination unit to a base station that manages a plurality of radio resources for each RAN Slice associated with a service.

Embodiments described herein relate to methods and apparatuses for controlling a mode of operation of a wireless device. A method in a base station comprises receiving, from a core network node, a first indication of a level of pending signalling or user plane data to be transmitted to the wireless device; and based on the first indication, controlling the mode of operation of the wireless device.

An apparatus for interfacing with a circuit switched network may be configured to detect when a data carrier signal from a circuit switched network is offline. While the data carrier signal from the circuit switched network is offline, the apparatus may send, to a network element coupled with the circuit switched network via the apparatus, control packets indicating that the data carrier signal is offline. The apparatus may further maintain an active data carrier signal between the apparatus and the network device by sending, to the network element, protocol idle frames. The apparatus may buffer, at the apparatus, packets sent from the network element to the circuit switched network. Once the data carrier signal is restored, the apparatus may send, to the circuit switched network, control packets indicating that the data carrier signal is online and the packet buffered at the apparatus while the data carrier signal is offline.

Disclosed are various embodiments that provide distributed user plane functions for radio-based networks. In one embodiment, data is received from a client device connected to a radio access network of a radio-based network. The data is forwarded to a user plane component of a user plane function. The user plane component is implemented in a computing device of the radio access network. The data is processed by the user plane component. The data that has been processed is then routed to a data network.

Embodiments herein relate to a method performed by a RAN node (12), for managing communication on a first network slice in a communications network (1). The communications network (1) comprises partitioned sets of functionalities. A first set of functionalities belongs to the first network slice. The first set of functionalities is at least 5 partly separated from another set of functionalities out of a total set of functionalities in the communications network (1). The RAN node (12) receives, from a CN node (16), information regarding requested resources for a first network slice identified by a network slice identifier. The RAN node (12) determines that the received information does not correspond to a Service Level Agreement (SLA) for the first network slice.
