A wireless communication network serves a User Equipment (UE) and exports UE capability data. A UE Capability Management Function (UCMF) receives the UE capability data and transfers the UE capability data to a Network Exposure Function (NEF). The NEF transfers the UE capability data to another wireless communication network. The UCMF receives additional UE capability data. The NEF receives a UE capability request for the UE from the other wireless communication network. In response, the NEF transfers the UE capability request for the UE to the UCMF. The UCMF transfers additional UE capability data to the NEF. The NEF transfers the additional UE capability data to the other wireless communication network.

The embodiment of the present disclosure provides a method for reporting and configuring MDT measurement, apparatus and electronic device using the same and medium. The method may be performed by a first access network node and includes: obtaining first MDT configuration information; performing MDT measurement according to the first MDT configuration information to obtain a first MDT measurement report; transmitting the first MDT measurement report to a first node, so that the first node combines a second MDT measurement report associated with the first MDT measurement report obtained by the first node with the first MDT measurement report; and/or receiving a third MDT measurement report transmitted by a second access network node, combining the third MDT measurement report and the first MDT measurement report, and transmitting the combined measurement report to a second node. The solution provided in the embodiment of the present disclosure provides an implementation method of reporting MDT measurement when performing MDT measurement at multiple nodes.

In order to prevent deterioration of QoE of a user in intersystem handover, an apparatus according to the present invention includes: an information obtaining unit configured to obtain network slice related information related to a network slice used by a terminal apparatus in a first radio communication system; and a first communication processing unit configured to transmit, to a second network node of a second radio communication system, a message for intersystem handover of the terminal apparatus from the first radio communication system to the second radio communication system, the message including the network slice related information.

A communications method and apparatus, the method including receiving, by a policy control network element, from a first session management network element, a policy request message, sending, by the policy control network element, to the first session management network element, according to the policy request message, policy information, where the policy information comprises a data network access identifier (DNAI), and establishing, by the first session management network element, according to the DNAI, a first user plane network element for a first protocol data unit (PDU) session for a terminal device.

The present disclosure relates generally to communications, and more particularly to communication methods and related devices and nodes for control plane traffic management. Among other things, the disclosure presents a method performed by a central unit (CU) of a network node for coordination of control plane traffic management during a communication device reconfiguration in a telecommunications network. The method may, e.g., comprise receiving information from a distributed unit (DU) of the network node alerting the CU to reset a packet data convergence protocol (PDCP) sequence number of control plane traffic signaled from the communication device as a consequence of an event in the telecommunications network; and responsive to receiving the information, resetting the PDCP sequence number of the control plane traffic signaled from the communication device.

The described technology is generally directed towards contextual network function selection and transfer. Techniques disclosed herein can be implemented at core network access management functions (AMFs). An AMF can obtain user equipment context information via a gNodeB (gNB). Rather than causing a local default session management function (SMF) and user plane management function (UPF) to process user equipment communications, the AMF can use a mapping function to identify, based on the user equipment context information, a proximal SMF and corresponding UPF which have a nearer proximity to the user equipment. The AMF can facilitate selection of the proximal SMF and UPF for the user equipment, and the AMF can transfer the user equipment context information to a proximal AMF that is better situated to serve the proximal SMF and UPF. By facilitating transfer to the proximal SMF and UPF, communication latency experienced by the user equipment can be reduced.

The embodiments of the present disclosure provide methods and apparatuses for control of Quality of Service (QoS). A method applied in a base station for control of QoS includes: receiving a Core Network (CN) flow identifier and information on a corresponding QoS parameter of a Packet Data Network (PDN) connection as transmitted from a CN control network element and creating a mapping relation between the CN flow identifier and the corresponding QoS parameter; and utilizing, after determining based on the received information on the QoS parameter of the PDN connection that a radio bearer satisfying a requirement of the QoS parameter exists between a user terminal and the base station, the existing radio bearer satisfying the requirement of the QoS parameter, creating a mapping relation between the existing radio bearer and the CN flow identifier of the PDN connection and transmitting information on the mapping relation to the user terminal.

A communication method includes a first IAB node receives a first message from a CU of an IAB donor, where the first message indicates the first IAB node to be handed over from a first parent node to a second parent node, and the first message includes a first IP address of the first IAB node. The first IAB node determines first transport network layer association information between the first IAB node and the CU of the IAB donor based on the first IP address. The first IAB node updates control plane context information of an F1 interface by using the first transport network layer association information, where the F1 interface is an interface between the first IAB node and CU of the IAB donor. An IAB node communicates with a CU of an IAB donor by using a first IP address as soon as possible after handover is completed.
