A method for UE route selection policy (URSP) rule matching regarding S-NSSAI and PDU session type is proposed. When an application is executed, a UE finds an RSD of a matching URSP rule, and the association of the application with an existing PDU session should have some exceptions. In one example, regarding S-NSSAI, if there's only a single allowed S-NSSAI or the UE is aware of the default S-NSSAI, the UE can associate the PDU session with the application where the existing PDU session is established with an S-NSSAI provided by the UE, but the RSD doesn't include any S-NSSAI. In another example, regarding PDU session type, the PDU session type IPv4v6 in the RSD can match with PDU session type IPv4 or IPv6 of the PDU session, which was established when the UE requested IPv4v6 during the PDU session establishment.

Embodiments herein relate to a method performed by a network node in a telecommunication network providing a multicast transmission to a group of devices residing in a cell of the telecommunication network. The network node monitors a congestion level for communication, and, if the congestion level reaches a first threshold, the network node orders for at least one device in a RRC connected mode to be released from the RRC connected mode to an RRC idle mode or an RRC inactive mode, thereby disabling a capability of the at least one device to provide one or more re-transmission requests while keeping an ability of the at least one device to further receive the multicast transmission.

An operation control module executes, in accordance with a predetermined rule, operation control corresponding to a degree of operation of a leader base station system included in one of base station system groups, with respect to a follower base station system included in the base station system group. The operation control module executes, in accordance with occurrence of a predetermined event, operation control different from the operation control performed in accordance with the predetermined rule, for the follower base station system which is included in one of the base station system groups, and in which a degree of similarity of a transition of the degree of operation with respect to the leader base station system is smaller than a predetermined magnitude.

Described are examples for repurposing mobility management with virtual radio in software radio access networks. A virtual mobile network includes a first server configured to host a first mobile network distributed unit (DU) for providing a first virtual cell to a plurality of user devices via a radio unit. The virtual mobile network also includes a second server configured to host a second mobile network distributed unit providing a second virtual cell via the same radio unit. A radio access network (RAN) intelligent controller (RIC) is configured to control the first DU and the second DU to hand over the plurality of user devices from the first virtual cell to the second virtual cell. The first server may then be shut down for maintenance or updates without dropping service to the user devices.

This application provides a communication method, apparatus, and system, to enhance quality of service of a service. The method includes: A terminal device determines first service information, where the first service information is used to describe a feature of a service of the terminal device; and the terminal device sends the first service information to a core network, where the first service information is used by the core network to determine a policy corresponding to the service. In this solution, the terminal device may provide the first service information for the core network, so that the core network can determine the policy for the terminal device based on the first service information. In this way, transmission quality of a data packet of a service of the terminal device is controlled.
