Wireless communications for paging are described. A wireless device may use a subset of beams, among a plurality of beams, to communicate with a base station during a connected state. After a connection release, at least one beam of the subset of beams may be used for paging associated with the wireless device.

The present disclosure relates to a communication method and system for converging a 5.sup.th-Generation (5G) communication system for supporting higher data rates beyond a 4.sup.th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. According to the disclosure, it is possible to efficiently support data forwarding during conditional handover and dual stack protocol handover.

The present disclosure pertains to a base station (BS) apparatus configured to provide communication for one or more user equipment (UEs). Some embodiments of this apparatus may include: a BS networking device configured to access actual wireless data pertaining to actual UEs and to access simulated wireless data pertaining to simulated UEs; an interface controller communicably interposed between the BS networking device and the UEs, the interface controller being configured to control the access to the actual wireless data and the simulated wireless data; and a bridging device configured to convert between a wireless protocol used by the UEs and a wired protocol used by the BS networking device.

A target RAN node (3) receives, from a core network (5), a message requesting a handover of a radio terminal (1) from a bearer-based network to a bearer-less network. This handover request message includes flow information related to at least one session to be established in the bearer-less network in order to transfer at least one packet flow of the radio terminal (1). The target RAN node (3) transmits, to the core network (5), a handover acknowledge response message containing a transparent container that includes a radio resource configuration information derived from the flow information and is to be forwarded to a source RAN node associated (2) through the core network (5). It is thus, for example, possible to appropriately configuring an AS layer of a target RAT in an inter-RAT handover.

In a communication system constituting a first core network and a second core network, a location management device deployed in a first core network initiates a switching procedure between the core networks. In the switching procedure, the second core network is selected by MME selection of a base station device, allowing a terminal device to connect to the second core network. This configuration provides a communication control method and the like for enabling a terminal device to switch between core networks in a communication system in which multiple core networks are overlaid.

A method and system for providing a fallback solution in a multi-tenant communication system is provided. A cloud-based call processing service receives a voice call initiation request from a first mobile device located at a first communication system. The voice call initiation request includes a request to complete a voice call with a second mobile device located at a second communication system. Resources are allocated at the first communication system and the second communication system. The cloud-based call processing service establishes a call between the first mobile device and the second mobile device. At some point the first communication system determines that it should fallback to single site operation. In fallback mode, call processing functionality is performed at the first communication system for the first mobile device.

To provide a communication procedure for data transmission and/or reception suitable to a CIoT terminal. In a communication control method by a terminal apparatus according to the present invention, a first data transmission and/or reception method is a method for transmitting and/or receiving user data by use of a Signalling Radio Bearer (SRB), a second data transmission and/or reception method is a method for transmitting and/or receiving user data by use of a Data Radio Bearer (DRB), and the communication control method includes a step of changing the user data transmission and/or reception method from the first data transmission and/or reception method into the second data transmission and/or reception method, and a step of transmitting and/or receiving the user data to/from a core network by the second data transmission and/or reception method.

An ‘open control network’ is described, wherein the control plane functions within the Radio Access Network (such as eNodeB and gNodeB) and Core Network (such as MME, AMF and SMF) provide an interface towards the operator and 3.sup.rd party control applications. Applications are allowed to securely register to signaling protocols within the control plane, specifically to the RAN or the Core Network control functions to view, intercept and intervene certain types of control messages or procedures. Innovative applications can be developed to view and modify control plane behavior utilizing both traditional methods as well as upcoming Machine Learning and Artificial Intelligence algorithms to provide services that are not part of standard operator offerings. An even more flexible control plane infrastructure is described by allowing operator services and/or non-operator services to subscribe to certain control functions/messages to manage in real-time certain user-group's behavior or enforce slice-specific behavior according to slice requirements.

A system and method for vehicle communication, including a computing device communicatively coupled with a roadside computing device disposed along a road, wherein the computing device is disposed remote from the road. The roadside computing device to communicate with a vehicle computing system of a vehicle on the road.

The present disclosure relates to a method of controlling a timeout event for a data packet transmission in a wireless communications network, and a node performing the method. In an aspect, a method of controlling a timeout event for a data packet transmission in a wireless communications network is provided, wherein a data packet retransmission timer initially is set to a timeout value indicating the maximum allowed round-trip time (RTT) for the data packet transmission and a timeout event occurs upon the retransmission timer expiring. The method includes observing the RTT for the data packet transmission over a connection in the network, increasing, upon the retransmission timer expiring before a measured value is available for the observed RTT, the timeout value for the retransmission timer, and determining whether a currently set timeout value for the retransmission timer is to be decreased or not.
