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.

Aspects of the present disclosure describe receiving, from at least one cell of a zone of multiple cells, a zone-specific signal related to the zone of multiple cells, wherein the zone of multiple cells operate using synchronized timing, acquiring, based on the zone-specific signal, a timing synchronization with a cell of the zone of multiple cells, and communicating with the cell based on the timing synchronization.

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.

A method, apparatus, and system are provided for slice and/or subscriber identification module (SIM) device locking/un-locking. In one embodiment, a method implemented in a user equipment, UE, having one or more subscriber identification module, SIM, is provided. The method includes activating one or more subscriber identification module, SIM for a UE. The method includes, as a result of activating, initiating a request to register the UE with a network, and receiving allowed Network Slice Selection Assistance Information, NSSAI. The method includes associating received one or more single-NSSAI, S-NSSAI, indicated by the allowed NSSAI to one of the one or more SIM in the UE according to a policy. The method includes using one of the one or more S-NSSAI associated to one of the activated SIM to establish a Packet Data Unit, PDU, session

Embodiments of the present disclosure provide a data transmission method, terminal, and base station, relate to the communications field, and can improve data packet transmission efficiency. The data transmission method includes: receiving, by a terminal in an idle state, a first resource sent from a base station, where the first resource is used by the terminal to send an uplink application layer data packet to the base station; and sending, by the terminal, on the first resource, the uplink application layer data packet to the base station. The data transmission method is applied to the data transmission system.
