The first communication path is for communicating the first traffic type between the IAB donor CU network node and an IAB network node. The method further comprises transmitting the first mapping to the IAB network node.

A service data flow transmission method, a communication apparatus, and a communication system. The method includes: a user plane network element receives characteristic information of a service data flow and QoS information of the service data flow, where the characteristic information of the service data flow indicates traffic characteristic information corresponding to different time slices of the service data flow in a time period, and the QoS information indicates QCIs corresponding to the different time slices; determines, based on the characteristic information of the service data flow, a first time slice corresponding to a data packet of the service data flow; and sends the data packet to an access network device based on the first time slice corresponding to the data packet of the service data flow and a QCI corresponding to the first time slice.

A communication method and apparatus. The method may be applied to a 4G system, a 5G system, and/or a future communication system such as a 6G system. The method includes: a splitting protocol layer entity of a terminal device configures a first sequence number SN of a splitting protocol layer in a first splitting protocol layer data packet, and configures a second SN of the splitting protocol layer in a second splitting protocol layer data packet. The splitting protocol layer entity of the terminal device sends the first splitting protocol layer data packet to a first protocol layer entity corresponding to a first access network device, and sends the second splitting protocol layer data packet to a first protocol layer entity corresponding to a second access network device.

A 5th generation (5G) or pre-5G communication system for supporting a higher data transmission rate after a 4th generation (4G) communication system such as long-term evolution (LTE). A method may be performed by an intelligent controller may, and include obtaining first information related to user equipment (UE) identity of an open (O)-RAN from an E2 node, obtaining second information related to the UE identity from a network exposure function (NEF) of a 5th generation (5G) core network (5GC), generating an A1 policy message through comparison based on the first information and the second information, and transmitting the A1 policy message to a near-real time (RT) radio access network (RAN) intelligent controller (RIC) via an A1 interface, the first information may include a general public subscription identifier (GPSI), an access and mobility management function (AMF) UE NGAP ID related to the 5GC and a globally unique AMF ID (GUAMI) related to the 5GC, and the second information may include an AMF UE NGAP ID related to the 5GC and a GUAMI related to the 5GC.

A method of and an application server and user equipment for providing at least one of chat and Voice over Internet Protocol, chat/VoIP, services to the mobile user equipment in a mobile telecommunications network. The mobile user equipment comprises a chat/VoIP client for accessing a chat/VoIP service application interfacing the mobile telecommunications network. The chat/VoIP service application interfaces a plurality of proprietary chat/VoIP clients for accessing a plurality of proprietary chat/VoIP communication environments operated by a plurality of chat/VoIP service providers, for providing chat/VoIP services to the chat/VoIP client of the mobile user equipment. The chat/VoIP client and the chat/VoIP service application may be arranged such that privileged use of the mobile telecommunications network is enabled, providing a session between the user equipment and a communication environment with a predetermined or agreed Quality of Service.

A method for the transmission of data from a data transmitter to a server by means of a cellular network using frequency sub-bands. A modem selects at least one sub-band from among the frequency sub-bands of the frequency plane, the transmitter obtains at least one frequency sub-band selected, the transmitter obtains information representing the quality of service of the connection between the transmitter and the server, the transmitter checks whether the information representing the quality is superior to or equal to a predetermined quality level, the transmitter notifies the modem of a prohibition of selection of at least one previously selected frequency sub-band if the information representing the quality of service of the connection between the transmitter and the server is inferior to the predetermined quality level.

Various embodiments provide a resource allocation method and an apparatus. In those embodiments, a terminal device obtains a first parameter indicating a maximum service data volume to be provided by an access network device for a first service in a first time length; and determines, based on the maximum service data volume, a resource of a media access control protocol data unit MAC PDU, the resource being occupied by buffered data of the first service. In those embodiments, the terminal device determines, based on the maximum service data volume of the first service, the resource of the MAC PDU. Compared with a conventional method, the maximum service data volume of the first service is considered. This helps improve reasonableness of allocating the resource of the MAC PDU to the data of the first service.
