[0164] 5G network is on the way of development, and the current focus is to support MBS. The MBS work item is developed on the existing 5G framework to support multicast and broadcast services. The downlink data transmission process of MBS in the 5G network can participate in the process shown in FIG. 1B. The MB-UPF network element is the anchor point of the MBS session, responsible for receiving broadcast / multicast data streams from the AS or MB-STF. The MB-UPF network element and the AS / MB-STF network element can transfer data streams based on multicast or unicast. The MB-UPF network element can distribute data streams to NR in two ways. The two ways include 5GC shared transmission and 5GC independent transmission. When NR supports MBS, the MB-UPF network element can use 5GC shared transmission to distribute broadcast / multicast data streams; when NR does not support MBS, the MB-UPF network element can use 5GC independent transmission to distribute multicast data streams.

[0165] 5GC shared transmission is that the MB-UPF network element and the NR network element directly establish a shared transmission channel, and then the NR transmits data streams to terminal devices through the Precision Time Protocol (PTP) and the Point-To-Multipoint (PTM). PTP transmission is similar to unicast transmission, and data can only be received by a single terminal; while PTM allows all terminals to receive the same data, which greatly saves air interface resources. PTP and PTM can be dynamically switched according to the number of terminals under the current NR, so that the 5G MBS system is more reliable and efficient than the Evolved Multimedia Broadcast Multicast Services (eMBMS) in technology.

[0166] 5GC independent transmission is that the MB-UPF network element sends data to the UPF network element in the core network device, and the UPF network element forwards the data to the NR. The MB-UPF network element and the UPF network element can transfer data based on multicast or unicast; the UPF network element can also send data to each NR according to user granularity in unicast mode, as shown in FIG. 1B, the UPF network element establishes PDU session A between NG-RAN2 and UE3, and transmits MBS data through PDU session A. The UPF network element establishes PDU session B between NG-RAN3 and UE4, and transmits MBS data through PDU session B.

[0521] The following is an exemplary introduction to the above method.

[0522] In this example, a CDN model is proposed to broadcast, multicast and unicast services through the CDN model, and NTN is combined with MBS to ensure that high-popularity content or resources can be broadcast / multicasted to improve the response efficiency of content or resources in the case of frequent request services.

[0523] As shown in FIG. 6, the UE can construct a CDN model through NTN and terrestrial cellular network to transmit MBS content or resources. The CDN model can include multiple edge networks, which include UPF, multiple access network devices and ground stations in the edge network. Among them, the ground station can communicate with the satellite. The UE can send a request to the edge network where it is located to obtain the requested MBS resource or content. The edge network queries locally, and if it is queried to feedback to the UE, if it is not queried locally, it can request other edge networks or core network. The UE can communicate with the edge network through the terrestrial cellular network when the quality of the terrestrial cellular network is good. The UE can communicate with the edge network through NTN when the quality of the terrestrial cellular network is poor in the offset area.

[0524] Among them, the CDN network can not only include a series of distributed cache servers, but also can serve as an intelligent content distribution network. The CDN model dynamically decides how to deliver content to the UE fastest according to real-time Internet traffic and various routing algorithms. Among them, edge computing and edge network are the key technologies of CDN, which can perform data processing at the edge of the network instead of in a central node or cloud, so as to make the calculation closer to the source of data, further reduce the delay and optimize the performance.

[0525] The 5G network features include 3GPP access and non-3GPP access, such as satellite. In addition, they have the advantage of supporting low latency by building edge clouds close to users to provide services. Therefore, the 5G edge cloud can support real-time services and reduce the amount of communication through the network. It helps to reduce the cost of network delivery. The traditional content delivery method has a content distribution server located in the network center. It receives content from the satellite through the user plane. In the multicast method, the satellite gateway can obtain the received content from the satellite at the edge cloud and the core cloud storage, respectively. Therefore, the proposed method has the advantage of reducing the number of channels through the UPF.

[0526] In some embodiments, the UE can directly access the satellite, which is more network resource saving. For example, in the case of supporting MBS with reduced deployment cost of 5G network in remote areas, the UE can receive MBS content or resources through the CDN model of NTN in places where there is no mobile 5G network, and can selectively determine the distribution mode of broadcast, multicast, unicast, etc. according to popularity, which can effectively reduce the delay and forwarding overhead of the signaling process and improve the performance of the system.

[0527] In this example, the CDN model is established from MBS using the NTN network, and broadcast, multicast, unicast, etc. can be selectively applied according to the characteristics of the popularity of the content, thereby saving the cost of deploying 5G network in remote areas. Moreover, it can effectively reduce the delay and forwarding overhead of the signaling process and improve the performance of the system.
