Although the SUL (Supplementary Uplink) design can add supplementary carriers, the supplementary form and the selectable carriers are also fixed, which is not flexible. Furthermore, the current carrier aggregation design also has many limitations, such as high requirements for UE (terminal) hardware and complex cell activation and deactivation.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0019] Currently, in the 5G standard of 3GPP (the 3rd Generation Partnership Project, an international standards organization responsible for developing and maintaining mobile communication technology specifications and technical reports including 3G, 4G, and 5G), the carrier in TDD cells (TDD cells refer to wireless communication cells using TDD (Time Division Duplex) technology, a type of full-duplex communication technology used in mobile communication systems) is fixed. In FDD cells (Frequency Division Duplex), carrier configuration (carrier configuration refers to the process of setting and adjusting carrier parameters in a communication system, including carrier frequency, bandwidth, etc., to achieve efficient information transmission and optimize communication performance) usually occurs in pairs, i.e., an uplink carrier and a downlink carrier combined. While SUL (Supplementary Uplink) designs can add supplementary carriers, the supplementary form and selectable carriers are fixed and inflexible. Furthermore, current carrier aggregation designs also have many limitations, such as high requirements for UE (terminal) hardware and complex cell activation and deactivation.

[0020] In a fully decoupled access network (a type of access network architecture characterized by not restricting the type and number of UNI (User-Network Interface) and SNI (Service Node Interface), not interpreting signaling, and being viewed as a transport network independent of services and applications, primarily used for cross-connection, multiplexing, and transmission functions), cells can be flexibly configured with carriers to form separate control cells, user downlink cells, and user uplink cells. Furthermore, downlink base stations, uplink base stations, and control base stations can be deployed independently. Existing inter-base station interface methods (such as Xn) and base station-core network interface methods (such as NG) cannot meet the requirements for flexible and efficient inter-base station collaboration. Figure 1 As shown ( Figure 1 In 5G networks, gNB (gN) is a base station used in 5G networks, while eNB (Evolved NodeB) is a base station used in 4G (LTE) networks. ng-eNB is an upgraded 4G base station used to support 5G core network interoperability.

[0021] To address the aforementioned issues, this invention proposes a base station deployment and service interface communication method based on a fully decoupled access network. In a fully decoupled access network (Decoupled-RAN), independent uplink and downlink base stations can be deployed based on the flexible configuration of uplink and downlink carriers, thus enabling various forms of inter-base station collaboration. Furthermore, a service interface is proposed for information exchange between base stations, between base stations and the core network, and between base stations and the application layer.

[0022] The preferred embodiment of the present invention describes a base station deployment and service interface communication method based on a fully decoupled access network, such as... Figure 2 As shown, the base station deployment and service interface communication method based on a fully decoupled access network includes the following steps: Step S10: Determine the fully decoupled access network and target deployment requirements, and deploy base stations in the fully decoupled access network according to the target deployment requirements to obtain the target configured base stations.

[0023] Among them, the fully decoupled RAN is an access network architecture. Its main feature is that it does not restrict the type and number of UNI (User-Network Interface) and SNI (Service Node Interface), does not interpret signaling, and can be regarded as a transport network that is independent of services and applications. It mainly performs cross-connection, multiplexing and transmission functions.

[0024] The target deployment requirements can be set according to the user's needs, and different configuration base stations can be deployed according to different needs, such as control base stations, uplink user base stations, downlink user base stations, and hybrid cell base stations.

[0025] Specifically, the target configuration base station includes a control base station, an uplink user base station, a downlink user base station, and a hybrid cell base station; wherein, the control base station is composed of multiple or a single control cell; the uplink user base station is composed of multiple or a single uplink cell; the downlink user base station is composed of multiple or a single downlink cell; and the hybrid cell base station is composed of the control cell, the uplink cell, and the downlink cell.

[0026] The present invention provides the following base station deployment method for a fully decoupled access network: The base station deployment method in a Decoupled-RAN (i.e., a fully decoupled access network) can be flexibly configured based on deployment requirements, allowing for flexible configuration of the cells of each base station. For example, a separate control base station can be configured, consisting of multiple or a single control cell; alternatively, separate uplink user base stations and downlink user base stations can be configured, consisting of multiple or a single uplink or downlink cell. Figure 3 As shown.

[0027] Meanwhile, hybrid cells can also be configured in Decoupled-RAN, such as a mixed combination of uplink / downlink user cells and control cells, for example... Figure 4 As shown.

[0028] Step S20: Determine the target core network in the fully decoupled access network, and configure the target core network and the target configuration base station with service-oriented interfaces to obtain the target configuration interface.

[0029] The target core network, or CN (Core Network), is the management center of the entire mobile communication network in Decoupled-RAN. It is responsible for processing data collected from base stations and then sending it to external networks (such as the Internet). All mobile terminals' network access rights are managed by the core network. The core network is not a specific device, but a collective term for many network elements (network units). In the Decoupled-RAN architecture, network elements within the core network are carried by an IP-based bearer network. The functions of the core network include, but are not limited to, IP-based architecture and functional separation. For example, in the transition from 2G to 3G, the 3G core network implemented IP-based architecture and refined network element functions, no longer integrating multiple functions into a single device, but rather separating them, each performing its own function. In the 5G era, the core network is further modularized and software-defined, supporting network slicing and MEC (Multi-access Edge Computing) functions. Therefore, in Decoupled-RAN, the role and function of the core network are consistent with the core network in the entire mobile communication network, serving as a crucial part of network management and data processing.

[0030] The target configuration interface includes the interface between target configuration base stations, the interface between target configuration base stations and the core network, and the interface between traditional base stations and target configuration base stations.

[0031] Specifically, a target core network in the fully decoupled access network is determined, a service-oriented network element (CSBI) is deployed in the target core network, and a service-oriented network element (RSBI) is deployed in the target configured base station; an RSBI-R interface is constructed between the target configured base stations, and bus-type communication is established between each target configured base station through the RSBI-R interface; an RSBI-C interface is constructed between the CSBI of the target core network and the RSBI of the target configured base station, and direct communication is established between the target core network and the target configured base station through the RSBI-C interface.

[0032] like Figure 5As shown, the service interface configuration process for the fully decoupled access network in this invention is as follows: In the Decoupled-RAN, service-oriented network elements CSBI and RSBI can be deployed in the core network CN (i.e., the target core network in this invention) and the base station (i.e., the target configuration base station in this invention). The RSBI can communicate with the RSBI in other Decoupled-RAN nodes (a Decoupled-RAN node refers to a node in the Decoupled-RAN architecture, here referring to the target configuration base station) via the RSBI-R interface (i.e., an RSBI-R interface is built between the target configuration base station and the bus communication is established between each target configuration base station through the RSBI-R interface), and can also communicate directly with the network element CSBI in the core network through the RSBI-C interface (i.e., a direct communication is established between the target core network and the target configuration base station through the RSBI-C interface).

[0033] The information transmitted in each interface may include: 1. The information transmitted through the RSBI-C interface includes: application layer commands (such as requirements for the RAN side, QoE requirements, measurement requirements, etc.), RAN side responses to the application layer, and application layer requirement information.

[0034] 2. The information transmitted through the RSBI-R interface includes: inter-base station coordination information (including the identity information of each base station, group information of cooperating base stations, etc.), base station measurement information, UE measurement information, and control signaling forwarding, etc.

[0035] Further, the centralized unit and the distributed unit inside the target configuration base station are obtained. If the centralized unit and the distributed unit are in a separate architecture, an RSBI-CU interface and an RSBI-DU interface are constructed. The centralized unit establishes a communication connection with the centralized unit or the distributed unit through the RSBI-CU interface. The distributed unit establishes a communication connection with the centralized unit or the distributed unit through the RSBI-DU interface. Within the same Decoupled-RANnode (target configuration base station), if an architecture is adopted that separates the CU (i.e., the centralized unit in this invention) and the DU (i.e., the distributed unit in this invention), the CU and DU can communicate with each other through the RSBI-CU and RSBI-DU interfaces, respectively. That is, the centralized unit establishes a communication connection with the centralized unit or the distributed unit through the RSBI-CU interface; the distributed unit establishes a communication connection with the centralized unit or the distributed unit through the RSBI-DU interface.

[0036] The information transmitted in each interface may include: 1. The information transmitted in the RSBI-CU interface includes: information generated by the CU, such as UE-related configuration messages, security-related information, UE context, mobility-related information, and QoS-related information. 2. The information transmitted in the RSBI-DU interface is information generated by the DU, such as scheduling-related information and modulation and coding-related information.

[0037] Furthermore, the interface method between the traditional base station and the preset base station is determined, and a communication connection between the traditional base station and the service-oriented network element (RSBI) of the target configured base station is established through the preset base station interface method; based on the communication connection between the traditional base station and the service-oriented network element (RSBI) of the target configured base station, a communication connection between the traditional base station and the service-oriented network element (CSBI) of the target core network is established.

[0038] like Figure 6 As shown, in a fully decoupled access network, a traditional base station can communicate with the Decoupled-RAN node (i.e., the target configuration base station in this invention) through Xn (Xn is the existing inter-base station interface method), and access the service interface of the core network through the service-oriented network element RSBI of the Decoupled-RAN node, or access the core network through AMF and UPF and then communicate with the service-oriented network element CSBI of the core network.

[0039] Step S30: Construct a base station group based on the target configuration base station and the target configuration interface, and perform inter-base station cooperative communication through the base station group.

[0040] A base station group refers to a collection of multiple configured base stations that communicate with each other through the RSBI-R interface. At the same time, a base station group can provide services to the UE (User Equipment) with a unified group identity and realize collaborative communication between base stations.

[0041] Specifically, a bus-type communication is established between each target configuration base station based on the RSBI-R interface to obtain a base station group, and it is determined whether the control base station is included in the base station group; if yes, the control base station performs resource configuration and communication management for other user base stations in the base station group; if no, a preset username base station is determined in the base station group, and the preset username base station performs resource configuration and communication management for other user base stations in the base station group.

[0042] like Figure 7 As shown, the process of the inter-base station coordination method for a fully decoupled access network in this invention is as follows: In a Decoupled-RAN (i.e., a fully decoupled access network), base stations can be connected in a bus manner through the RSBI-R interface in the RSBI service element. Base stations can form a group (i.e., a base station group in this invention), or they can communicate individually with other base stations or the core network through the service element RSBI or a traditional interface. The formed base station group can provide services to the UE (User Equipment) with a unified group identity. The base station group has a group ID (i.e., Decoupled-RAN group ID). If there is a control base station in the group, the control base station can uniformly configure and manage other uplink and downlink user base stations in the Decoupled-RAN group (i.e., the base station group in this invention). If there is no control base station in the group, one of the user name base stations (i.e., the preset user name base station in this invention) can be responsible for resource configuration. The coordination information between base stations is uniformly communicated via bus through RSBI. The configuration method of the base station group can be configured by the base station itself according to the actual environment, or recommended by the core network or application layer.

[0043] The messages transmitted via RSBI-R in the Decoupled-RAN base station group may include: 1. Group management information (join requests and responses, group leave requests and responses, etc.); 2. Resource allocation (scheduling information, power control, etc.) requests and responses; 3. Paging and response for transmitting collaborative information (status synchronization information); 4. Control signaling and user data forwarding, paging, and response.

[0044] Step S40: Determine the target application layer, and establish cooperative communication between the target configuration base station and the target application layer based on the target configuration interface and the target core network.

[0045] The target configuration base station and the target application layer need to communicate through the target core network. The target configuration interface first establishes a connection with the target core network through the RSBI-C interface, and then realizes collaborative communication with the target application layer based on the service-oriented network element CSBI of the target core network.

[0046] Specifically, a direct communication is established between the target core network and the target configured base station based on the RSBI-C interface, the target application layer is determined, and a communication connection is established between the service-oriented network element (CSBI) of the target core network and the target application layer through the network open function component; the service-oriented network element (RSBI) in the target configured base station establishes a communication connection with the target application layer through the service-oriented network element (CSBI) of the target core network.

[0047] like Figure 8 As shown, in a Decoupled-RAN (fully decoupled access network), the base station (i.e., the target configuration base station in this invention) can communicate with the target core network's CSBI via the RSBI. The CSBI can then use NEF (Network Open Function Component) to provide network capability openness and coordination to the application layer. The RSBI can also communicate directly with the application layer (i.e., the target application layer in this invention) via the CSBI. The target configuration base station can obtain configuration information and transmit data to the target application layer through the above methods, and the target application layer can also utilize the above paths to obtain relevant information and data from the base station.

[0048] The application layer can be designed with unified transport and application layer protocols with CSBI and RSBI (such as QUIC+HTTP / 3; TCP / UDP+HTTP / 2, etc.).

[0049] Furthermore, such as Figure 9 As shown, based on the above-described base station deployment and service interface communication method based on a fully decoupled access network, the present invention also provides a base station deployment and service interface communication system based on a fully decoupled access network, wherein the base station deployment and service interface communication system based on a fully decoupled access network includes: The base station deployment module 51 is used to determine the fully decoupled access network and the target deployment requirements, and to deploy base stations in the fully decoupled access network according to the target deployment requirements to obtain the target configured base station; The service interface configuration module 52 is used to determine the target core network in the fully decoupled access network, and to perform service interface configuration on the target core network and the target configuration base station to obtain the target configuration interface; The base station coordination module 53 is used to construct a base station group based on the target configured base station and the target configured interface, and to perform inter-base station coordinated communication through the base station group. Application layer collaboration module 54 is used to determine the target application layer and establish collaborative communication between the target configuration base station and the target application layer according to the target configuration interface and the target core network.

[0050] Furthermore, such as Figure 10 As shown, based on the above-mentioned base station deployment and service interface communication method and system based on a fully decoupled access network, the present invention also provides a terminal, which includes a processor 10, a memory 20 and a display 30. Figure 10 Only some of the terminal components are shown; however, it should be understood that it is not required to implement all of the components shown, and more or fewer components may be implemented instead.

[0051] In some embodiments, the memory 20 may be an internal storage unit of the terminal, such as a hard disk or memory. In other embodiments, the memory 20 may be an external storage device of the terminal, such as a plug-in hard disk, smart media card (SMC), secure digital card (SD), flash card, etc. Further, the memory 20 may include both internal and external storage devices. The memory 20 is used to store application software and various types of data installed on the terminal, such as program code installed on the terminal. The memory 20 can also be used to temporarily store data that has been output or will be output. In one embodiment, the memory 20 stores a base station deployment and service interface communication program 40 based on a fully decoupled access network. This base station deployment and service interface communication program 40 based on a fully decoupled access network can be executed by the processor 10, thereby implementing the base station deployment and service interface communication method based on a fully decoupled access network in this application.

[0052] In some embodiments, the processor 10 may be a central processing unit (CPU), a microprocessor, or other data processing chip, used to run program code stored in the memory 20 or process data, such as executing the base station deployment and service interface communication method based on the fully decoupled access network.

[0053] In some embodiments, the display 30 may be an LED display, a liquid crystal display, a touch-sensitive liquid crystal display, or an OLED (Organic Light-Emitting Diode) touchscreen. The display 30 is used to display information on the terminal and to display a visual user interface.

[0054] In one embodiment, when the processor 10 executes the base station deployment and service interface communication program 40 based on the fully decoupled access network in the memory 20, the following steps are performed: Determine the fully decoupled access network and target deployment requirements, and deploy base stations in the fully decoupled access network according to the target deployment requirements to obtain the target configured base stations; Determine the target core network in the fully decoupled access network, and perform service-oriented interface configuration on the target core network and the target configured base station to obtain the target configuration interface; A base station group is constructed based on the target configured base station and the target configured interface, and inter-base station cooperative communication is performed through the base station group; The target application layer is determined, and collaborative communication between the target configuration base station and the target application layer is established based on the target configuration interface and the target core network.

[0055] The target configuration base station includes a control base station, an uplink user base station, a downlink user base station, and a hybrid cell base station; The control base station consists of multiple or a single control cell; The uplink user base station consists of multiple or a single uplink cell; The downlink user base station consists of multiple or a single downlink cell; The hybrid cell base station consists of the control cell, the uplink cell, and the downlink cell.

[0056] Specifically, determining the target core network in the fully decoupled access network and configuring service interfaces for the target core network and the target configured base station to obtain the target configuration interface includes: Determine the target core network in the fully decoupled access network, deploy the Service-Oriented Network Element (CSBI) in the target core network, and deploy the Service-Oriented Network Element (RSBI) in the target configured base station; An RSBI-R interface is constructed between the target configuration base stations, and bus-type communication is established between each target configuration base station through the RSBI-R interface; An RSBI-C interface is constructed between the service-oriented network element CSBI of the target core network and the service-oriented network element RSBI of the target configuration base station, and a direct communication between the target core network and the target configuration base station is established through the RSBI-C interface.
