According to one embodiment of the present disclosure, the method by means of which a mobility management entity (MME) determines the communication mode of a terminal in a communication system includes the steps of: receiving, from the terminal, an access request including information on the position of the terminal; transmitting a message to a home subscriber server (HSS) on the basis of the received access request; receiving, from the HSS, specific position information for setting a first mode; comparing the information on the position of the terminal with the specific position information; and determining the communication mode of the terminal according to the result of the comparison. According to the present disclosure, the frequent transmission of small amounts of data can be supported in an efficient manner.

There is provided a solution for balancing application content processing in a mobile communication network. According to an aspect, a method comprises: determining to handover content processing of application data of a terminal device from a first network element to a second network element, wherein one of the first network element and the second network element is configured to perform multi-access edge computing and the other one of the first network element and the second network element is an application server in a core network or beyond the core network from a perspective of the multi-access edge computing; and transmitting at least one handover message to handover the content processing of the application data from the first network element to the second network element.

A network node, a wireless device and methods performed thereby for use in a Random Access, RA, procedure with wireless devices in a cell of the network node are provided. The method includes receiving, from at least two wireless devices, a RA message comprising an RA preamble; transmitting an RA Response, RAR, to the at least two wireless devices, the RAR comprising a TC-RNTI and an RA preamble identifier identifying the received RA preamble; and receiving, from each of said at least two wireless devices, a connection request message comprising a respective S-TMSI. The method includes for a wireless device previously connected to the network node in the same cell, transmitting a connection setup message addressed to a C-RNTI previously assigned to the wireless device; and for a wireless device not previously connected to the network node in the same cell, transmitting, a connection setup message addressed to the TC-RNTI.

A radio access network (RAN) node (11) is configured to send, to another RAN node (12), first control information regarding at least one of one or more bandwidth parts (BWPs) configured in a system bandwidth. It is thus, for example, possible to contribute to inter-radio access network (RAN) node (e.g., inter-gNB) signaling enhanced to handle bandwidth parts.

This application relates to the communications field, and provides a cell handover method and apparatus. The method is applied to a communications system. The system includes at least a source wireless gateway, a target wireless gateway, and a forwarding device. Both the source wireless gateway and the target wireless gateway are connected to the forwarding device by using a first interface, and the forwarding device is connected to an application server by using the first interface. The method includes: determining, by the source wireless gateway, the target wireless gateway for a terminal based on a measurement report, and sending, by the source wireless gateway, a handover instruction message to the terminal when receiving a handover request acknowledgment message sent by the target wireless gateway.

A network node, a wireless device and methods for use in a Random Access, RA, procedure with wireless devices in a cell of the network node. The method of the network node comprises receiving, from at least two wireless devices, a RA message having an RA preamble; transmitting an RA Response, RAR, to the wireless devices, the RAR having a TC-RNTI and an RA preamble identifier identifying the received RA preamble; and receiving, from each of wireless the devices, a connection request message having a respective S-TMSI. For a wireless device previously connected to the network node in the same cell, a connection setup message addressed to a C-RNTI previously assigned to the wireless device is transmitted. For a wireless device not previously connected to the network node in the same cell, a connection setup message addressed to the TC-RNTI is transmitted.

The disclosure relates to a communication technique for convergence of a fifth-generation (5G) or pre-5G communication system for supporting a higher data transmission rate beyond a fourth-generation (4G) communication system, such as Long-Term Evolution (LTE), with an IoT technology, and a system therefor. The disclosure may be applied to an intelligent service (for example, smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security and safety-related service, etc.) on the basis of a 5G communication technology and an IoT-related technology. A method and an apparatus is provided for applying two-step random access when 3rd generation partnership project (3GPP) 5G new radio (NR) technology is used in an unlicensed band.
