A method (100) for managing resource usage across domains in a communication network is disclosed. The communication network comprises a radio access domain, a core domain and a transport domain providing connectivity between the radio access domain and the core domain. The method comprises receiving from the core domain an indication of load status of gateway nodes in the core domain (110), receiving from the transport domain an indication of load status of transport resources in the transport domain (120), normalising across the core and transport domain a cost of using resources in each domain (130), calculating, on the basis of the normalised costs, optimal chains of resources in the core and transport domains for providing a service from different radio access nodes to different possible Access Point Names (APNs) (140), and sending to the core and transport domains information about the calculated optimal resource chains (150). Also disclosed are methods for managing resource usage in a core domain, a transport domain and a radio access domain of a communication network, together with cross domain, core domain, transport domain and radio access domain control elements.

One aspect provides a method performed by a radio access network node in a telecommunications network. The method comprises: responsive to detection of a trigger event associated with a wireless device having a connection to the telecommunications network via the radio access network node or seeking to establish a connection to the telecommunications network via the radio access network node, transmitting, directly to a user plane core network node, a message initiating establishment of a user-plane tunnel for the connection between the radio access network node and the user plane core network node. The message comprises one or more of: an indication of an identifier of the wireless device; and an indication of an identifier of a session for the wireless device, and further comprises an indication of a downlink tunnel endpoint identifier of the radio access network node.

An approach to automatically provision a data service name (APN or DNN) when an endpoint device connects to a mobile network is described. A methodology includes receiving from an endpoint device a first request to connect to a mobile network, the first request including an identifier of the endpoint device and a default data service name, responsive to detecting the default data service name, determining, from the identifier of the endpoint device, a group to which the endpoint device belongs along with a corresponding group identifier for the group, querying a repository with the group identifier, and receiving, in response, an assigned data service name that is associated with the group identifier, providing the assigned data service name to the endpoint device, and receiving from the endpoint device a second request to connect to the mobile network, the second request including the assigned data service name.

Systems and methods for redirecting Radio Resource Control (RRC) messages in a wireless system that uses Central Unit (CU)/Distributed Unit (DU) splitting and either network sharing or network slicing are disclosed. In some embodiments, a method performed by a shared Distributed Unit (DU) comprises receiving a RRC message from a User Equipment (UE) and sending a first DU-to-Central Unit (CU) message to a first CU, where the first DU-to-CU message comprises the RRC message. The method further comprises either obtaining an indication that the first CU is a wrong CU for the RRC message or determining that the first CU is a wrong CU for the RRC message. The method further comprises sending another DU-to-CU message to a second CU, where the other DU-to-CU message comprises the RRC message or a RRC message related to the RRC message.

A disclosure of the present specification provides a method for selecting, by a user equipment (UE) located outside a coverage of a base station, a neighboring UE with which the UE will perform device-to-device (D2D) communication. According to the method, it is possible to quickly find out whether a neighboring UE is located within the coverage of a base station and is capable of operating as a relay, through a DMRS and a detection signal received from the neighboring UE.

A Long Term Evolution (LTE) network connects wireless communication devices to an Internet. In the LTE network, a Packet Data Network Gateway (P-GW) exchanges user communications between the wireless communication devices and the Internet. The P-GW determines a number of additional wireless communication devices the P-GW can serve and transfers the number to a Mobility Management Entity (MME). The MME allocates a new wireless communication device to the P-GW based on the number of additional wireless communication devices reported by the P-GW. The MME may redirect one of the wireless communication devices to the P-GW based on the number.

A location management device function is provided in an access network, and a base station identifies and authenticates a terminal device permitted to perform base station loopback communication on the basis of identification information on the terminal device received from the terminal device. With this configuration, provided is a communication control method and the like for the base station device that has lost connectivity to a core network, to permit only specific terminals to perform base station loopback communication.

A method is disclosed for handling cloud computing resources in a wireless communication network comprising a first and a second access subnetwork providing wireless access to wireless communication devices residing in a first and a second geographic area, respectively, and a first and a second cloud computing resource connected to the first and the second access subnetwork, respectively. The method comprises obtaining mobility information over a time period for the wireless communication devices of when, during the time period, each of the devices has wireless access to the communication network via the first access subnetwork and when they have wireless access to the communication network via the second access subnetwork. The method also comprises selecting which of the first or second cloud computing resource that is to serve each of the devices based on the obtained mobility information, and sending an instruction to each of the devices to connect to a server that is connected to the selected cloud computing resource for that wireless communication device.

The present invention relates to a 5G or pre-5G communication system for supporting higher data transmission rate compared to a beyond 4G communication system such as LTE. A method for using resources by an electronic device in a wireless mobile communication system can comprise the steps of: setting dedicated wireless access configuration for each service; detecting a first service request; and, on the basis of the setting, transmitting and receiving a signal using a dedicated wireless access configuration corresponding to the first service. The present invention is not limited to the embodiment and can pertain to other embodiments.

Embodiments describing methods performed by a system comprising Network functions including at least a Session Management Function and a User Plane Function for performing a UPF re-anchoring for an application triggered at a User Equipment over an established Packet Data Unit (PDU) Session, where when the system receives the initial trigger for a service triggered by the application (e.g., a DNS request or an application level request), a determination is made by the system based on the information related to the application that re-anchoring of the UPF for that application into a local UPF closer to the UE is required. When re-anchoring of the UPF is successful, the initial trigger is discarded, and the UE is instructed to establish a new PDU session over the local UPF for that application.
