The NS-BRI comprises i) first maximum bit rate information (MBRI) specifying a first maximum bit rate for the network slice and the user equipment, and / or ii) first guaranteed bit rate information (GBRI) specifying a first aggregate guaranteed bit rate for the network slice and the user equipment.

Systems and methods for wireless communication are disclosed herein. In one embodiment, the systems and methods are configured to receive, by a mobility management function (AMF) from a network function (NF), slice information including at least one of a quality of service (QoS) profile of a slice or a service area of the slice. The AMF can determine that a wireless communication device is authorized to access the slice based on the service area of the slice. The AMF can send, to a radio access network, the QoS profile including a slice-specific aggregate maximum bit rate (AMBR) specific to the slice.

A method of rate limiting per radio access technology or across radio access technologies is provided that includes receiving a request related to a session management (SM) policy association for protocol data unit (PDU) session establishment / modification for a user equipment (UE) associated with a network slice. The method includes receiving information indicating a remaining maximum bit rate associated with a group of one or more PDU sessions associated with the network slice. The remaining maximum bit rate has a value that is specific to a radio access technology (RAT) type of a radio access network (RAN) to which the UE is connected or a value that is common across at least two RAT types including the RAT type of the RAN. And the method includes making a policy decision to accept or reject the establishment / modification of the SM policy association based on whether the value of the remaining maximum bit rate is higher than a value of a granted maximum bit rate for the PDU session.

A method for splitting data traffic from a UE in an O-RAN where UL data is transmitted from the UE to a MeNB.DU and to a SgNB.DU according to an UL AMBR for the UE where if the UL data packet split between the MeNB.DU and SgNB.DU violates a UL AMBR associated with either DU, the UL data packets are buffered at the DU and a message is transmitted to the other DU to determine if it can accept the buffered data packets such that the DU will analyze its UL AMBR and will accept the data packets or a portion thereof, if its UL AMBR is not violated. Also, a method where MeNB DU and SgNB.DU negotiate with each other to decide suitable values of UL AMBR via their respective air-interfaces.

In some implementations, a network device may receive, from a server, video traffic associated with an application, wherein the application is associated with a video content provider.

The embodiment of the application provides a communication method and device, and relates to the technical field of communication. In the communication method, after a terminal device switches an access network element, it is determined that the execution state of a first event of the switched access network element is different from that of the access network element before the switching, and first information is sent to a policy control network element. Since the first information indicates that the execution state of the first event of the access network element has changed, the policy control network element determines the state of the execution of the first event according to the first information, wherein the first event is to limit the transmission rate of the terminal device in a slice according to the maximum bit rate, and the execution state of the first event includes executing the first event or not executing the first event. Thus, a mechanism for controlling the maximum bit rate of the terminal device in the slice is provided.
