Abstract: Embodiments of the present disclosure provide a data packet transmission method and a virtual network group. The solution is as follows: when receiving a first data packet sent by a first UE, a first UPF forwards the first data packet to a first group communication UPF according to a first forwarding rule issued by a first SMF; the first group communication UPF sends the first data packet to a second group communication UPF by using a first communication tunnel according to a destination address in the received first data packet; the second group communication UPF forwards the received first data packet to a second UPF according to a second forwarding rule issued by a second SMF; and the second UPF sends the received first data packet to a second UE. According to the technical solution provided by the embodiments of the present disclosure, multiple SMFs are deployed in virtual networks, so that cross-SMF communication is realized.

Abstract: The present disclosure relates to a method, device, and system for limiting a data rate of a network slice user, and a storage medium. The method for limiting the data rate of the network slice user includes: performing, by a policy control function network element, a unified rate limit on a guaranteed bit rate (GBR) data stream and a non-guaranteed bit rate (non-GBR) data stream of the network slice user in case where a user equipment initiates a slice data session establishment request or a slice data session modification request.

Abstract: Provided in the embodiments of the present application is a relay transmission method. The method includes: establishing a first protocol data unit session connection between a relay and a network; establishing a second protocol data unit session connection between a first relay and a user equipment; and according to a multi-path transmission control protocol connection between the user equipment and a non-third generation partnership project interworking function entity, making the user equipment connect to the network via both the first relay and a second relay when performing signal transmission with the network.

Abstract: This disclosure provides a network resource pre-allocation method, device, system, and medium, wherein the method includes: an NWDAF acquiring historical record information of a user accessing a service, and generating user service preference prediction and suggestion information according to the historical record information; and the NWDAF sending the user service preference prediction and suggestion information to a network function (NF) so that the NF pre-allocates a network resource according to the user service preference prediction and suggestion information.

Abstract: A system and method provides seamless switchover of a user device (UE) between a mobile data network and a wireless network while providing policy and charging control (PCC) of the data session in the mobile data network. A mobile core network component is made ASF aware to process user data traffic related to an auto switching function (ASF) server from a UE client located on the UE using a special access point name (APN). The mobile core network component then uses a dedicated deep packet inspection (ASF DPI) for all data transfers to the special APN. The core network component is then able to process the UE data traffic seamlessly as the traffic is toggled between the ASF tunnel the WiFi tunnel. By monitoring the data traffic on the ASF tunnel, the core component (GGSN/PGW) is able to provide PCC for the data session.
