The present application relates to a method and apparatus for selecting user plane function. One embodiment of the subject disclosure provides a method for selecting User Plane Function (UPF), comprising: getting, by a Session Management Function (SMF), application information in a Protocol Data Unit (PDU) session during a PDU Session Establishment procedure or during Domain Name System (DNS) Query processing; and selecting, by the SMF, the UPF based on the application information.

This application discloses a route information storage method. The method is applied to a wireless mesh network, the wireless mesh network includes a first node, a second node, and at least two stations STAs, the first node is an upper-level node of the second node, the at least two STAs include a first STA and a second STA, and the first STA and the second STA are connected to the second node. In the method, the first node receives a routing request for access requested by the first STA, and if it is determined that a first route entry corresponding to the second STA already exists, the first node no longer generates a new route entry for the first STA, but reuses the first route entry.

This application discloses a service processing method for a proximity service, a device, and a system, and relates to the field of wireless communication technologies, to resolve a problem such as inappropriate charging caused because a network side does not perform, in proximity service (ProSe) communication, service supervision or service management on a data packet transmitted by remote user equipment (UE) via relay UE. In this application, a first network element (for example, an access and mobility management function AMF network element or a session management function SMF network element) may obtain, based on relay information that is received from the remote UE and that includes a relay service code or first indication information indicating that the remote UE is to transmit a service in relay mode, policy configuration information for detecting or monitoring service data forwarded by the relay UE.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus of a central or management entity of an integrated access and backhaul (IAB) network may receive a report indicating one or more of a failure associated with a communication link associated with an IAB node included in the IAB network or a quality of service (QoS) associated with the communication link. The apparatus may modify a topography of the IAB network or routing within the IAB network when the report indicates the failure associated with the communication link. The apparatus may verify a QoS associated with the IAB network when the report indicates the QoS associated with the communication link. Numerous other aspects are described.

Advances in wireless technologies have resulted in the ability of a wireless communication system to support wireless communications of different standards, e.g., 5G, LTE, and Wi-Fi. Different Wireless standards have aspects which are very different from each other. Described in the present disclosure are embodiments of architecture with hardware and software split to allow implementation of different wireless standards along a configurable signal process path. The configurable signal process path comprises software configurable operators that may be configured in a desired level of granularity to load desirable software to process signals of various standards on the same hardware. Embodiments of the disclosed architecture with hybrid hardware and software implementation may improve system operation efficiency and lower system complexity to serve communications across multiple wireless standards.

A method of communication between nodes in a telecommunications network. Each node maintains a copy of a shared digital ledger, is identified by a respective identification code and implements a software application configured to manage the transmission of data packets and maintain the shared digital ledger. The method includes: memorizing a list of identification codes, each code identifying a respective node included in a subset of nodes of the network, identifying a receiver node to transmit the data packet, generating a data packet to be delivered to a recipient node, transmitting to the first node of the minimum sequence of nodes the data packet, issuing a request to the network nodes to record the data packet transmission in the distributed ledger, and when a data packet is received, the method requires that each receiver node, other than the recipient node of the data packet, repeats at least some steps.

A method of provisioning UE Route Selection Policy (URSP) rules received from a non-subscribed Stand-alone Non-public Network (SNPN) registered using credentials from a credentials holder (CH) is provided. After a UE register to the non-subscribed SNPN using credentials from the CH, the UE may establish a PDU session for accessing services n the SNPN. Prior to establishing the PDU session, the UE checks the corresponding URSP rules that can be used in the SNPN. If the UE is signaled with URSP rules by the registered non-subscribed. SNPN, UE should store the URSP rules and then apply those URSP rules for PDU session establishment when the UE access the services in the non-subscribed SNPN.

A data transmission method, apparatus, device, and a computer-readable storage medium are provided. The data transmission method of the present disclosure includes receiving data sent by a User Equipment UE, determining a Session Management Function SMF, and forwarding the data to the SMF, wherein after the SMF receives the data, the SMF forwards the data to a User Plane Function UPF.
