Abstract

[0003] This method of using "cell" as the basic unit of wireless resource management is difficult to support the needs of 5G networks in two types of services: massive machine type communications (mMTC) and ultra-reliable and low latency communications (URLLC). Therefore, 5G has carried out patch-style switching enhancements, using dual connectivity (DC) and multiple connectivity (MC), and even introducing duplication in the packet data convergence protocol (PDCP) to achieve seamless switching, that is, data is repeatedly sent on multiple radio link control (RLC) links connected to a PDCP.
[0004] The existing 5G RRC achieves seamless switching through DC and MC enhancements. The user equipment (UE) needs to switch between the primary cell group / secondary cell group (MCG / SCG) and within the MCG, even if the MCG / SCG is on the same centralized unit-distributed unit (CU-DU) base station.

[0079] See also Figure 1 , Figure 1 A block diagram of a wireless communication system applicable to an embodiment of the present invention is shown. 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 user equipment (UE, User Equipment), and the terminal 11 may be a terminal side device such as a mobile phone, a tablet personal computer (Tablet Personal Computer), a laptop computer (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.

The network device 12 can be a base station and / or a core network element, wherein the above-mentioned base station can be a base station of 5G and later versions (for example: gNB, 5G NR NB, etc.), or a base station in other communication systems (for example: eNB, WLAN access point, or other access point, etc.), wherein the base station can be called a node B, an evolved node B, an access point, a base transceiver station (Base Transceiver Station, 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 B node, an evolved B node (eNB), a home B node, a home evolved B node, a WLAN access point, a WiFi node or some other suitable term in the field. As long as the same technical effect is achieved, the base station is not limited to specific technical vocabulary. It should be noted that in the embodiment of the present invention, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.
[0080] The base station can communicate with the terminal 11 under the control of a base station controller, and in various examples, the base station controller can be part of the core network or certain base stations. Some base stations can communicate control information or user data with the core network via a backhaul. In some examples, some of these base stations can communicate with each other directly or indirectly via a backhaul link, which can be a wired or wireless communication link. The wireless communication system can support operations on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on these multiple carriers at the same time. For example, each communication link can be a multi-carrier signal modulated according to various radio technologies. Each modulated signal can be sent on a different carrier and can carry control information (e.g., reference signals, control channels, etc.), overhead information, data, etc.
[0081] The base station can communicate wirelessly with the terminal 11 via one or more access point antennas. Each base station can provide communication coverage for its respective coverage area. The coverage area of the access point can be divided into sectors that constitute only a portion of the coverage area. The wireless communication system may include different types of base stations (e.g., macro base stations, micro base stations, or micro-micro base stations). The base station may also utilize different radio technologies, such as cellular or WLAN radio access technologies.

[0083] Please refer to Figure 2 , a structure of a wireless resource control function entity module 20 of a base station in an embodiment of the present invention is given, including: at least one of a control plane unit 21, a wireless resource plane unit 22 and a user context plane unit 23. Figure 2 The diagram of the interaction between the above three units is shown in FIG.
[0084] The control plane unit 21 is used to obtain user context information and / or wireless resource requirement information of the terminal after receiving a connection establishment request message or a connection modification request message sent by the terminal, send the wireless resource requirement information of the terminal to the wireless resource plane unit, and / or send the user context information of the terminal to the user context plane unit.
[0085] Here, the user context information may specifically include at least one of the following: an identity identifier of the terminal, service information, transmission bearer information, transmission channel information, and the like.
[0086] The wireless resource plane unit 22 is used to store or manage the resource information of each air interface entity and the resource usage rules of the air interface entity in units of air interface entities. After receiving the wireless resource requirement information of the terminal sent by the control plane unit, wireless resources are allocated to the terminal according to the resource information and / or resource usage rules of the air interface entity, and the wireless resource allocation result is sent to the user context plane unit.
[0087] Here, the air interface entity is a cell or a predefined entity other than a cell used to represent air interface resources, and the cell includes a physical cell and / or a logical cell. In addition, the wireless resource allocation result may specifically include at least one of the following: a) air interface entity cluster information obtained by combining one air interface entity or multiple air interface entities, and the air interface entity cluster information includes at least one of the following information: a cluster identification ID, a mapping relationship between an air interface entity cluster and an air interface entity; b) wireless resource information of each air interface entity and usage rules corresponding to the wireless resource information.
[0088] The user context plane unit 23 is used to store or manage the user context information of the terminal sent by the control plane unit, and / or, according to the radio resource allocation result of the terminal sent by the radio resource plane unit, record the resources of the air interface entity occupied by the terminal.
[0089] Here, the radio resource control functional entity module matches the terminal (UE) with the radio resources in units of air interface entities (such as cells), and selects the radio resources of the appropriate air interface entity (such as cells) to provide services for the UE according to the RRC signaling sent by the UE. For example, when a user accesses, an available service cell can be assigned to the UE. When the UE moves, the service cells available to the user can also be updated. In this solution, RRC matches the UE with the radio resources in units of cells, and selects the radio resources of the appropriate cell to provide services for the UE according to the RRC signaling application sent by the UE.
[0090] In the above units, the control plane unit 21 is responsible for controlling the wireless resource plane unit 22 and the user context plane unit 23. After receiving a connection establishment or modification request sent by the terminal, the user context information of the terminal is written into the user context plane unit, and the wireless resource demand required for the terminal is sent to the wireless resource plane unit. After the wireless resource plane unit completes the allocation of wireless resources, the allocation result is sent to the user context plane unit and reported to the control plane unit. The control plane unit can start the subsequent control process and complete the subsequent signaling process, such as sending a related response message.
[0091] The radio resource plane unit 22 is responsible for storing or managing the resource information of each air interface entity, for example, it is responsible for storing the resource information of each physical cell (Physical Cell: cellular cell of the air interface) in units, including the power, time domain resources and frequency domain resources of the physical cell, and also storing or managing the use rule parameters for these resources, such as discontinuous reception (DRX) parameters, semi-persistent scheduling (Semi-Persistent Scheduling, SPS) parameters, etc. After receiving the radio resource demand information sent by the control plane unit, according to the terminal request in the request information, the radio resource information is allocated: cluster information after the combination of one or more physical cells, including the ID of the cluster, the mapping relationship between the cluster and each of its physical cells; the radio resource information of each physical cell and the use rule parameters corresponding to the resource information, etc.
[0092] The user context plane unit 23 is responsible for storing or managing user context information, for example, it is responsible for storing the corresponding context in units of terminals received by the control plane unit, recorded as the user context of the terminal. The user context plane unit stores the context information of each terminal, including the identity information, service information, transmission bearer information and transmission channel information of the terminal, and when the radio resource plane unit allocates resources to the terminal, the user context plane unit can also record the resources allocated to the terminal, such as physical cell resources. When the terminal is released, it is necessary to send release information to the radio resource plane unit to release the resources occupied by the terminal, such as physical cell resources.
[0093] Through the above units, the embodiment of the present invention realizes a design scheme of separating management and control of the RRC layer. It can be seen that the embodiment of the present invention reconstructs the existing RRC functional architecture, changes the existing technology of using cellular cells as the basic invalid resource management unit, realizes the separation of "management" and "control" at the RRC level, simplifies the complexity of wireless resource control on the network side, and reduces the implementation cost.
[0094] In an embodiment of the present invention, the radio resource plane unit is further used to send a radio resource allocation result to the control plane unit after allocating radio resources to the terminal. The control plane unit is further used to send a message carrying the radio resource allocation result to the terminal after receiving the radio resource allocation result sent by the radio resource plane unit. Here, the message can specifically be a message for indicating radio resource modification, or a response message for establishing a radio resource control connection, or other predefined messages.
[0095] When the connection of the terminal needs to be released, the control plane unit may also be used to receive a connection release request message sent by the terminal, and send first release information for releasing the resources of the air interface entity occupied by the terminal to the wireless resource plane unit. At this time, the wireless resource plane unit may also be used to release the resources of the air interface entity occupied by the terminal according to the first release information.
[0096] In an embodiment of the present invention, the control plane unit is further used to receive a context establishment, deletion or modification request message sent by the terminal, and to send the context establishment, deletion or modification request message to the wireless resource plane unit; the wireless resource plane unit is further used to allocate, recycle or update the resources of the air interface entity for the terminal (for example, allocating the maximum available power to the terminal, etc.) according to the context establishment, deletion or modification request message, and send the resource information of the air interface entity allocated, recovered or updated for the terminal to the user plane context unit.
[0097] In addition, to achieve mobility management, the control plane unit is also used to receive a cell reselection or handover request from the terminal, determine a target cell for cell reselection or handover; and, when both the source cell and the target cell for the cell reselection or handover are cells under the wireless resource control function entity module, send a wireless resource allocation request for the cell reselection or handover to the wireless resource plane unit. The wireless resource plane unit is also used to allocate wireless resources for the cell reselection or handover according to the wireless resource allocation request, and send the wireless resource allocation result allocated for the cell reselection or handover to the user context plane unit. The user context plane unit is also used to update the resources of the air interface entity occupied by the terminal according to the wireless resource allocation result allocated for the cell reselection or handover.
[0098] If the control plane unit determines that the source cell and the target cell of the cell reselection or handover belong to cells under different radio resource control function entity modules, the control plane unit sends a radio resource allocation request for the cell reselection or handover to the target radio resource plane unit, and the target radio resource plane unit is a radio resource plane unit under the radio resource control function entity module to which the target cell belongs; and after receiving a confirmation message of the completion of the cell reselection or handover sent by the target radio resource plane unit, the control plane unit sends a second release message for releasing the resources of the air interface entity occupied by the terminal to the radio resource plane unit. At this time, the radio resource plane unit is also used to release the resources of the air interface entity occupied by the terminal according to the second release message.
[0099] For example, when a UE moves, if it is within the control range of an RRC functional entity, such as a CU platform running RRC signaling, the radio resource plane unit only needs to update the physical resources of the corresponding user context plane unit under the unified control of the control plane unit. If it exceeds the control range of an RRC functional entity, the source control plane unit needs to send the corresponding resource requirements to the target control plane unit to achieve relay allocation of physical cell resources.
[0100] In an embodiment of the present invention, the wireless resource plane unit is also used to pre-select a candidate target cell for the terminal to reselect or switch, and to send a pre-establishment message carrying information of the candidate target cell to the control plane unit; at this time, the wireless resource plane unit is also used to pre-establish a connection between the candidate target cell and the core network for the terminal according to the pre-establishment message, and to send a link switching signaling to the terminal for switching the air interface link to the candidate target cell when the terminal moves to the candidate target cell.
[0101] For example, the radio resource plane unit can select the target cell that the UE may switch to in advance based on artificial intelligence (AI) and big data tools, and then trigger the control plane unit to pre-establish the target cell in advance. When the UE actually moves to the target physical cell, it initiates air interface link switching signaling to achieve fast switching.
[0102] In an embodiment of the present invention, the radio resource plane unit is further used to allocate one air interface entity, multiple air interface entities or one air interface entity cluster to the terminal according to the reception quality of the air interface signal of the air interface entity by the terminal and the load of the air interface entity. The control plane unit is further used to select an air interface entity to send data and / or signaling to the terminal according to the reception quality of the air interface signal of each air interface entity when the number of air interface entities allocated to the terminal is greater than one.
[0103] In the embodiment of the present invention, the control plane unit is further used to initiate random access through the air interface entity of the terminal, configure information of available air interface entities in the random access process for the terminal; and perform signaling and data interaction with the terminal through the available air interface entity.
[0104] In the embodiment of the present invention, the control plane unit is further used to receive a measurement report reported by the terminal, and configure an available air interface entity in a random access process for the terminal according to the measurement report.
[0105] For example, the radio resource plane unit allocates one or more physical cells or cell clusters to the UE according to the signal quality of the cell received by the UE at the air interface and the load information of the cell. One or more physical cells or cell clusters serving a UE are equal, and there is no distinction between primary cells and secondary cells. The access procedures such as broadcasting, paging, random access (RA) process, RRC connection setup / reconfiguration / deletion (RRC Connection Setup / Recfg / Delete) for the UE are sent in the cell with high reception quality of the UE under the unified coordination and control of the control plane unit. When the number of physical cells serving a UE is 1, the control plane unit controls the signaling and data to interact through the cell. When the number of physical cells serving a UE is greater than 1, the control plane unit flexibly selects the appropriate physical cell to send signaling and / or data according to the signal quality received by the UE on each physical cell (signaling and data can be sent on different physical cells). Through the above processing, the embodiment of the present invention can cancel the concept of "PCell", because the core information of the UE belongs to the user context plane unit, and "PCell" only represents one or a group of physical layer cells with the best air interface channel quality of the UE, which belongs to the on-demand allocation of the wireless resource plane unit.
[0106] Initially, the UE side can monitor the broadcast and paging of multiple physical cells at the same time, and select the cell with the best received signal quality to initiate the RA process and RRC Connection related processes. The network side control plane unit configures the UE with the physical cell information available in the RA process in the physical cell where the UE initiates the RA process. After the UE side receives the configuration on the network side, it uses the configured physical cell as the "PCell" for signaling interaction or key information interaction within the air interface period configured by the network side; the network side control plane unit dynamically configures the UE side with a suitable "PCell" set based on the measurements reported by the UE side.
[0107] From the above, it can be seen that the embodiment of the present invention can simplify the complexity of network-side wireless resource control and reduce the implementation cost by reconstructing the existing RRC functional architecture. Based on the above structure, the embodiment of the present invention can achieve indiscriminate cell definition. In addition, the above structure has good scalability and can quickly support massive users. Moreover, the above structure has good compatibility and is compatible with 3G / 4G / 5G and other networks.
