[0002] In order to meet the increasing demand for wireless data communication services since the deployment of 4G communication systems, efforts have been made to develop improved 5G or pre-5G communication systems. Thus, 5G or pre-5G communication systems are also referred to as "ultra 4G networks" or "post-LTE systems".

[0003] Wireless communication is one of the most successful innovations in modern history. Recently, the number of subscribers to wireless communication services has exceeded 5 billion and is continuing to grow rapidly. Due to the increasing popularity of smart phones and other mobile data devices (e.g., tablet computers, laptop computers, netbooks, e-book readers, and machine type devices) among consumers and enterprises, the demand for wireless data services is growing rapidly.

[0075] Figure 1 It is an exemplary system architecture 100 of System Architecture Evolution (SAE). The User Equipment (UE) 101 is a terminal device for receiving data. The Evolved Universal Terrestrial Radio Access Network (E-UTRAN) 102 is a radio access network, which includes macro base stations (eNodeB / NodeB) that provide access to the wireless network interface for the UE.

The Policy and Charging Rules Function entity (PCRF) 106 provides Quality of Service (QoS) policies and charging guidelines. The Serving GPRS Support Node (SGSN) 108 is a network node device in the Universal Mobile Telecommunications System (UMTS) that provides routing for data transmission. The Home Subscriber Server (HSS) 109 is the home subscription subsystem of the UE, which is responsible for protecting user information including the current location of the user equipment, the address of the serving node, the user's security information, and the packet data context of the user equipment.

[0076] Figure 2 It is an exemplary system architecture 200 according to various embodiments of the present disclosure. Other embodiments of the system architecture 200 can be used without departing from the scope of the present disclosure.

[0077] The User Equipment (UE) 201 is a terminal device for receiving data. The Next Generation Radio Access Network (NG-RAN) 202 is a radio access network, which includes base stations (gNB or eNB connected to the 5G Core Network 5GC, and the eNB connected to the 5GC is also called ng-gNB) that provide access to the wireless network interface for the UE. The Access and Mobility Management Function entity (AMF) 203 is responsible for managing the mobility context and security information of the UE. The User Plane Function entity (UPF) 204 mainly provides user plane functions. The Session Management Function entity SMF205 is responsible for session management. The Data Network (DN) 206 includes services such as those of the operator, access to the Internet, and third-party services.

[0078] In the NR system, to support network function virtualization, more efficient resource management and scheduling, the base station (gNB / ng-eNB) that provides a wireless network interface for the user equipment (UE) can be further divided into a central unit gNB-CU / ng-eNB-CU (gNB central unit / ng-eNB central unit) and a distributed unit gNB-DU / ng-eNB-DU (gNB distributed unit / ng-eNB distributed unit) (referred to as CU and DU in this application for short), as Figure 3 (a) shows. The gNB-CU has radio resource control (RRC), service data adaptation protocol (SDAP: Service Data Adaptation Protocol), and packet data convergence protocol (PDCP) protocol layers, etc. The ng-eNB-CU has RRC and PDCP layers. The gNB-DU / ng-eNB-DU has radio link control protocol (RLC), media access control (MAC), and physical layer, etc. The standardized open interface between the gNB-CU and the gNB-DU is F1, and the standardized open interface between the ng-eNB-CU and the ng-eNB-DU is W1. The F1 interface is divided into a control plane F1-C and a user plane F1-U. The transport network layer of the F1-C is based on IP transport. To transmit signaling more reliably, the SCTP (Stream Control Transmission Protocol) protocol is added on top of IP. The protocol at the application layer is F1AP (F1 Application Protocol / F1 interface application protocol), see 3GPP TS38.473. SCTP can provide reliable application layer message transmission. The transport layer of the F1-U (F1-User, the user plane of F1) is UDP / IP, and GTP-U (GPRS Tunnelling Protocol for the user plane) is used on top of UDP / IP to carry user plane protocol data units (PDUs). Further, for the gNB-CU, as Figure 3(As shown in (b), the gNB-CU may include a gNB-CU-CP (control plane part of the central unit of the base station) and a gNB-CU-UP (user plane part of the central unit of the base station). The gNB-CU-CP contains the functions of the control plane of the base station and has the RRC and PDCP protocol layers. The gNB-CU-UP contains the functions of the user plane of the base station and has the SDAP and PDCP protocol layers. The standardized public interface between the gNB-CU-CP and the gNB-CU-UP is E1, and the protocol is E1AP. Refer to 3GPP TS38.463.
