Methods supporting a Quality of Service (QoS) update during a Handover (HO) procedure are disclosed herein. More specifically, methods performed by a Radio Access Network (RAN) node and a Core Network (CN) node for supporting a QoS update during an HO are provided. The methods disclosed herein can facilitate flexible New Generation (NG)-RAN (NG-RAN) deployment with a mixture of NG-RAN nodes capable or incapable of supporting additional parameters in an HO procedure. The methods also make it possible to provide smooth NG-RAN software updates between different software releases.

A method for communicating between base stations of two different wireless communication networks may include (1) transmitting a setup request message from a first base station of a first wireless communication network to a second base station of a second wireless communication network, the setup request message including a first user equipment (UE) device context format of the first wireless communication network and a second UE device context format of the second wireless communication network; (2) receiving, at the first base station, a setup response from the second base station, the setup response including a union of the first UE device context format and the second UE device context format; and (3) at the first base station, communicating with the second base station according to the union of the first UE device context format and the second UE device context format.

A control plane function entity for session management is operative to enable 5G to 4G to 3G mobility for a user equipment (UE). Initially, the entity may communicate one or more messages in a procedure for a handover of a session of the UE from a Fifth Generation System (5GS) to an Evolved Packet System (EPS). The entity may identify whether one or more indications indicate a need to provide 2G and/or 3G parameters. Based on identifying the one or more indications, the entity may communicate one or more messages in a bearer modification procedure with a bearer Quality of Service (QoS) update. In some implementations, the control plane function entity may identify the need to provide the 2G and/or the 3G parameters when the session is originally established in 5GS or when QoS parameters of a QoS Flow of the session are modified while the UE was in 5GS.

The end-to-end experience of a wireless customer depends on at least data throughput, data loss, and latency, as well as other characteristics. The user’s quality of experience (QoE) can be determined based on applications and measurements taken at the application layer of the user’s user equipment (UE) and information at the session level at the UE initiated and configured by an operator at the start of the session. The QoE is an application layer measurement configured by the operator and reported inside the application layer. When a UE is performing an inter-system handover, the QoE measurement configuration of the current session cannot be transferred from the source network to the target network.

A method is performed in a first infrastructure equipment for a handover of a wireless device from the first infrastructure equipment as a source to a second infrastructure equipment as a target. The method comprises maintaining a mapping between a plurality of packet bearers and a data radio bearer for the wireless device, each of the plurality of packet bearers being configured to provide a specified quality of service, determining that the wireless device should handover from the first infrastructure equipment to the second infrastructure equipment, determining that the second infrastructure equipment does not support the mapping of the plurality of packet bearers to the data radio bearer, and providing an indication of a mapping of the plurality of packet bearers for the second infrastructure equipment after handover to one of a core network equipment and the second infrastructure equipment.

This application provides a communication method and apparatus, and relates to the field of communication technologies, to ensure service continuity of an MBS of a terminal device in a cell handover process. The method includes: A first access network device configures, as a second radio bearer that is used to carry a unicast service, a first radio bearer that is currently used to carry an MBS between the first access network device and a terminal device. The first access network device sends the MBS to the terminal device in a unicast mode through the second radio bearer.

The disclosure relates to a method and apparatus for monitoring and changing information about quality of service (QoS) allowed to be supported to a user equipment (UE) in a mobile communication system, and an operating method of a target base station (BS) in the mobile communication system includes receiving, from a source BS, alternative quality of service (QoS) profile (AQP) information, determining whether information matching QoS information allowed to be supported for a UE to be served is included in the AQP information, and when the information matching the QoS information allowed to be supported for the UE to be served is included in the AQP information, transmitting the matching information to an access and mobility management function (AMF).

A first base station receives a second base station addition request indicating, for each packet flow of packet flows of a wireless device, whether each packet flow is for at least one vehicle-to-everything (V2X) service, and a quality-of-service indicator of each packet flow. The first base station sends an indication of an acceptance or rejection of each packet flow of the packet flows.

Facilitating management of network resource allocation based on device effective isotropic radiated power in advanced networks (e.g., 4G, 5G, and beyond) is provided herein. Operations of a method can comprise receiving, by a system comprising a processor, a first indication of a baseband output power of a mobile device and a second indication of a minimum peak effective isotropic radiated power of the mobile device. Further, the method can comprise scheduling, by the system, uplink physical resource blocks based on the first indication and the second indication, wherein the scheduling is performed during initial access. The method can also include communicating the device EIRP between network nodes during handover such that a target network device obtains the device EIRP from a source network device.

An enterprise private network includes a simplified Third Generation Partnership Project (3GPP) core architecture for interworking between an Evolved Packet System (EPS) and a Fifth Generation (5G) system (5GS). The architecture includes an Evolved Packet Core (EPC) control plane (CP) (EPC CP) unit and a 5G core (5GC) CP (5GC CP) unit. The 5GC CP unit receives, from the EPC CP unit via an N26 interface, a message indicating a forward relocation request responsive to an indication of a handover of a Packet Data Network (PDN) connection at a user plane node from the EPS to the 5GS. The 5GC CP node establishes a Protocol Data Unit (PDU) session corresponding to the PDN connection based on PDN connection information in the message, which includes establishing a Quality of Service (QoS) Flow corresponding to an EPS bearer, and manages the PDU session at the user plane node.
