Description

Interaction method and equipment between components of radio resource control entity

Technical Field

The present invention relates to the field of mobile communications technologies, and in particular, to a method and an apparatus for interaction between components of a radio resource control entity.

Background

The functions of radio resource control (Radio Resource Control, RRC) of the fifth generation mobile communication (5G) and the fourth generation mobile communication (4G) are basically the same, i.e. the access/establishment/removal of the user, the coverage of the network, the resource scheduling, the mobility management, the signaling control, the planning/optimization, etc. are performed by using the cell as the center, and the independent cell is used.

This approach, which takes "Cell" as the basic radio resource management unit, has difficulty supporting the requirements of 5G networks on both massive machine type communications (massive Machine Type Communications, mctc) and Ultra-reliable and low latency communications (URLLC). Therefore, the 5G further performs patched handover enhancement, and by adopting a dual connection (Dual Connectivity, DC) and multiple connection (Multiple Connectivity, MC), a multiplexing (multiplexing) manner is introduced even in the packet data convergence protocol (Packet Data Convergence Protocol, PDCP) to implement Seamless (seal) handover, that is, a manner in which data is repeatedly transmitted on a plurality of radio link control (Radio Link Control, RLC) links connected to one PDCP.

The prior art 5G RRC enables seamless handover by means of DC and MC enhancements, where the User Equipment (UE) needs to switch between primary cell group/secondary cell group (MCG/SCG), and inside the MCG, even if the MCG/SCG is on the same concentrated unit-distributed unit (CU-DU) base station.

The patch type implementation mode greatly increases the complexity of the network side and the terminal side, increases the implementation cost and has low practical value.

Referring to fig. 1, fig. 1 is a block diagram of a wireless communication system to which an embodiment of the present invention is applicable. The wireless communication system includes a terminal 11 and a network device 12. The terminal 11 may also be referred to as a User terminal or a User Equipment (UE), and the terminal 11 may be a terminal-side Device such as a mobile phone, a tablet Computer (Tablet Personal Computer), a Laptop (Laptop Computer), a personal digital assistant (Personal Digital Assistant, PDA), a mobile internet Device (Mobile Internet Device, MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device, which is not limited to a specific type of the terminal 11 in the embodiment of the present invention. The network device 12 may be a base station and/or a core network element, where the base station may be a 5G or later version base station (e.g., a gNB, a 5G NR NB, etc.), or a base station in another communication system (e.g., an eNB, a WLAN access point, or other access points, etc.), where the base station may be referred to as a node B, an evolved node B, an access point, a base transceiver station (Base Transceiver Station, a BTS), a radio base station, a radio transceiver, a basic service set (Basic Service Set, BSS), an extended service set (Extended Service Set, ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, or some other suitable terminology in the field, and the base station is not limited to a specific technical vocabulary, and in the embodiment of the present invention, the base station in the NR system is merely an example, but is not limited to a specific type of the base station.

The base stations may communicate with the terminal 11 under the control of a base station controller, which may be part of the core network or some base stations in various examples. Some base stations may communicate control information or user data with the core network over a backhaul. In some examples, some of these base stations may communicate with each other directly or indirectly over a backhaul link, which may be a wired or wireless communication link. A wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multicarrier transmitter may transmit modulated signals on the multiple carriers simultaneously. For example, each communication link may be a multicarrier signal modulated according to various radio technologies. Each modulated signal may be transmitted on a different carrier and may carry control information (e.g., reference signals, control channels, etc.), overhead information, data, and so on.

The base station may communicate wirelessly with the terminal 11 via one or more access point antennas. Each base station may provide communication coverage for a respective corresponding coverage area. The coverage area of an access point may be partitioned into sectors that form only a portion of that coverage area. A wireless communication system may include different types of base stations (e.g., macro base stations, micro base stations, or pico base stations). The base station may also utilize different radio technologies, such as cellular or WLAN radio access technologies. The base stations may be associated with the same or different access networks or operator deployments. The coverage areas of different base stations, including coverage areas of the same or different types of base stations, coverage areas utilizing the same or different radio technologies, or coverage areas belonging to the same or different access networks, may overlap.

The communication link in the wireless communication system may include an Uplink for carrying Uplink (UL) transmissions (e.g., from the terminal 11 to the network device 12) or a Downlink for carrying Downlink (DL) transmissions (e.g., from the network device 12 to the terminal 11). UL transmissions may also be referred to as reverse link transmissions, while DL transmissions may also be referred to as forward link transmissions. Downlink transmissions may be made using licensed bands, unlicensed bands, or both. Similarly, uplink transmissions may be made using licensed bands, unlicensed bands, or both.

The SBA architecture is applied to a 5G core network, and the main characteristic of the SBA is that flexible interaction (service) between functional modules (also called components) can be realized through a standard service model, and each component can be flexibly loaded as required. In the 5G core network, the logic control functions are abstracted into independent network function components, and these independent network function components can be flexibly combined according to service requirements. The network function component and other components are logically decoupled and the network function supports neutral interfaces, which can be converted into a single interface by providing services to other network function callers through the same interface message, thereby reducing the number of interfaces. The network functions provide management functions such as registration, discovery, monitoring and the like of the network functions, and the mutually independent characteristics ensure that the existing network services are not affected in the process of adding or upgrading the network functions. The componentized control plane architecture can implement plug and play through flexible orchestration of network functions.

Fig. 2 provides a structure of a radio resource control entity 20 of a base station, and the radio resource control entity 20 may also be referred to as a radio resource control entity module, specifically including: at least one of a control plane unit 21, a radio resource plane unit 22, and a user context plane unit 23. A schematic of interactions between the above 3 units is shown in fig. 2. In particular, the method comprises the steps of,

the control plane unit 21 is configured to obtain user context information and/or radio resource requirement information of a terminal after receiving a connection establishment request message or a connection modification request message sent by the terminal, send the radio resource requirement information of the terminal to the radio resource plane unit, and/or send the user context information of the terminal to the user context plane unit.

Here, the user context information may specifically include at least one of: the identity of the terminal, service information, transmission bearing information, transmission channel information and the like.

The radio resource plane unit 22 is configured to store or manage, in units of air interface entities, resource information of each air interface entity and a resource usage rule of the air interface entity, allocate radio resources for the terminal according to the resource information and/or the resource usage rule of the air interface entity after receiving the radio resource requirement information of the terminal sent by the control plane unit, and send a radio resource allocation result to the user context plane unit.

Here, the air interface entity is a cell or a predefined other entity than a cell for representing an air interface resource, where the cell includes a physical cell and/or a logical cell. In addition, the radio resource allocation result may specifically include at least one of the following: a) Air interface entity or air interface entity cluster information obtained by combining a plurality of air interface entities, wherein the air interface entity cluster information comprises at least one of the following information: a mapping relation between the cluster identification ID and the empty entity cluster and the empty entity; b) And the wireless resource information of each air interface entity and the use rule corresponding to the wireless resource information.

The user context plane unit 23 is configured to store or manage user context information of the terminal sent by the control plane unit, and/or record, according to a radio resource allocation result of the terminal sent by the radio resource plane unit, resources of an air interface entity occupied by the terminal.

Here, the radio resource control entity matches a terminal (UE) with radio resources in units of an air interface entity (e.g., a Cell), and selects a radio resource of an appropriate air interface entity (e.g., a Cell) to serve the UE according to RRC signaling sent by the UE. For example, when a user accesses, the UE may be assigned an available serving cell. The serving cells available to the user may also be updated as the UE moves. In the scheme, the RRC is used for matching the UE with the radio resources taking the Cell as a unit, and selecting the radio resources of a proper Cell to provide service for the UE according to the RRC signaling application sent by the UE.

Among the above units, the control plane unit 21 is responsible for controlling the radio resource plane unit 22 and the user context plane unit 23, after receiving a connection establishment or modification request sent by a terminal, writing user context (context) information of the terminal into the user context plane unit, sending a radio resource requirement needed for the terminal to use to the radio resource plane unit, after the radio resource plane unit finishes the allocation of radio resources, sending an allocation result to the user context plane unit, reporting the allocation result to the control plane unit, and the control plane unit can start a subsequent control flow to finish a subsequent signaling flow, such as sending a related response message.

The radio resource plane unit 22 is responsible for storing or managing resource information of each air interface entity, for example, in units of Physical cells (air interface cells), including power, time domain resources, frequency domain resources, and the like of the Physical cells, and also storing or managing usage rule parameters for these resources, such as discontinuous reception (Discontinuous Reception, DRX) parameters, semi-persistent scheduling (Semi-Persistent Scheduling, SPS) parameters, and the like. After receiving the radio resource demand information sent by the control plane unit, distributing the radio resource information according to the terminal request in the request information: cluster information after the combination of one or more physical cells, including the ID of the cluster, the mapping relationship of the cluster and each physical cell thereof; radio resource information of each physical cell, usage rule parameters corresponding to the resource information, and the like.

The user context plane unit 23 is responsible for storing or managing user context information and the like, for example, for storing corresponding contexts in units of terminals received by the control plane unit, and recording as user contexts of the terminals. The user context surface unit stores context information of each terminal, including identity information, service information, transmission bearer information, transmission channel information, and the like of the terminal, and when the radio resource surface unit allocates resources to the terminal, the user context surface unit may also record the resources allocated to the terminal, such as physical cell resources. When the terminal releases, release information needs to be sent to the radio resource plane unit to release resources occupied by the terminal, such as physical cell resources.

Fig. 2 provides an RRC architecture capable of implementing management and control separation, where RRC matches UE with radio resources in Cell units, and selects radio resources of a suitable Cell to serve the UE according to an RRC signaling application sent by the UE.

On the basis of introducing Artificial Intelligence (AI), the interaction relationship between the functions of the parts in fig. 2 needs to be defined, so that the architecture has enough flexibility and extensibility when facing the 6G system.

In view of the above, embodiments of the present invention provide an architecture of a Radio Resource Control (RRC) entity based on an SBA architecture. A flexible interaction mode among all modules is defined in a radio resource control entity based on an SBA architecture, and the compatibility of unstructured information is realized, so that a unified radio resource control functional entity (also called as a radio resource control functional entity module) is realized.

The above functional components may interact with data through a unified Service-based Architecture Interface (SBAI) architecture interface. That is, each SBAI may interact with data using a unified interface protocol. In addition, each functional component is connected to a Bus (Bus). The Bus (Bus) is a cloud platform system for information routing and interaction.

In the cloud system, a Bus (Bus) is a cloud platform system, and various information routing and interaction are realized through the functions of the cloud platform system. In the case of a non-cloud system, the Bus (Bus) may be a data packet of the radio resource control entity storage system, for example, may be part of the RRC-RRPF.
