When a terminal device with dedicated slice functionality moves to the coverage area of ​​an access network device that does not support that dedicated slice, or when the available resources of the cell to which the terminal device is to be handed over cannot meet the requirements of the dedicated slice service, the terminal device will no longer be able to support the dedicated slice service, resulting in the dedicated slice service of the terminal device not being effectively guaranteed.

[0033] In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0034] like Figure 1 As shown, Figure 1 A schematic diagram of a communication system provided in an embodiment of this application is shown. The communication system includes: a slice operation management platform 101, a terminal device 102, an access network device 103, and a core network device 104.

[0035] The slice operation management platform 101 is used to obtain the first information of at least one first cell within a target time period, and to determine the target cell from at least one first cell based on the first information of at least one first cell.

[0036] The first information of the first cell includes at least one of the following: whether the target slice is supported, the number of resources to be allocated, and the second information. The second information includes at least one of the following: reference signal receiving power (RSRP), physical resource block (PRB) resource utilization, and radio resource control (RRC) connection count; the first cell is at least one of the neighboring cells of the terminal device whose signal strength meets the requirements.

[0037] Optionally, the slice operation management platform 101 is a slice operation management platform that supports the target slice. It can be used to initiate and monitor the services of the target slice so that the actual performance and alarm status of the target slice services can be analyzed at any time.

[0038] Terminal device 102 is used to subscribe to target slice services and interact with access network device 103 to complete the aforementioned target slice services.

[0039] Terminal device 102 is a device with wireless communication capabilities that can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted, or on water (such as on ships). It can also be deployed in the air (e.g., on airplanes, balloons, and satellites).

For example, terminal equipment 102 includes handheld devices with wireless connectivity, vehicle-mounted devices, etc. Currently, terminal device 102 can be: mobile phone, tablet computer, laptop computer, handheld computer, mobile internet device (MID), wearable device (such as smartwatch, smart bracelet, pedometer, etc.), vehicle-mounted device (such as car, bicycle, electric vehicle, airplane, ship, train, high-speed rail, etc.), virtual reality (VR) device, augmented reality (AR) device, wireless terminal in industrial control, smart home device (such as refrigerator, television, air conditioner, electricity meter, etc.), smart robot, workshop equipment, wireless terminal in self-driving, wireless terminal in remote medical surgery, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, or wireless terminal in smart home, flying equipment (such as smart robot, hot air balloon, drone, airplane), etc. In one possible application scenario of this application, the terminal device is a terminal device that frequently operates on the ground, such as an in-vehicle device. In this application, for ease of description, the chip deployed in the above-mentioned device, such as a system-on-a-chip (SOC), a baseband chip, or other chips with communication functions, can also be referred to as terminal device 102.

[0041] Optionally, the terminal device 102 can be an embedded communication device or a user handheld communication device, including mobile phones, tablets, etc.

[0042] As an example, in this embodiment, the terminal device 102 can also be a wearable device. Wearable devices, also known as wearable smart devices, are a general term for devices that utilize wearable technology to intelligently design and develop everyday wearables, such as glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not merely hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are feature-rich, large in size, and can achieve complete or partial functions without relying on a smartphone, such as smartwatches or smart glasses, as well as those that focus on a specific type of application function and require the use of other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0043] Access network device 103 is used to activate the target slice service and interact with terminal device 102 to complete the target slice service.

[0044] Optionally, the operation and maintenance center (OMC) of the access network device 103 can be used to send configuration parameters of the target slice to the access network device 103 so that the access network device 103 can support the services of the target slice.

[0045] Access network equipment 103 includes, but is not limited to: access points (APs) in WiFi systems, such as home gateways, routers, servers, switches, bridges, etc.; evolved NodeBs (eNBs), radio network controllers (RNCs), NodeBs (NBs), base station controllers (BSCs), base transceiver stations (BTSs), home base stations (e.g., home-evolved NodeBs, or home NodeBs (HNBs)); base band units (BBUs); wireless relay nodes; wireless backhaul nodes; transmission and reception points (TRPs) or transmission points (TPs); 5G base stations, such as gNBs in new radio (NR) systems, or transmission points (TRPs or TPs); one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system; or network nodes constituting gNBs or transmission points, such as base band units (BBUs) or distributed units (TRPs). Access network equipment 103 includes various types of base stations, such as DU (Dedicated Unit), roadside units (RSU) with base station functionality, and NG radio access network (NG-Ran) equipment.

Access network equipment 103 further includes different types, such as terrestrial base stations, airborne base stations, and satellite base stations.

[0046] The core network device 104 is used to activate the target slice and interact with the terminal device 102 to configure the configuration parameters of the target slice for the terminal device 102 and to complete the target slice services.

[0047] In one possible implementation, the core network device 104 can also interact with the terminal device 102 through the access network device 103.

[0048] Optionally, the OMC of the core network device 104 can be used to send configuration parameters of the target slice to the core network device 104 so that the core network device 104 can support the services of the target slice; it can also collect, analyze and report alarm information and performance parameters of the core network device 104.

[0049] It should be noted that, Figure 1 This is just an example framework diagram. Figure 1 The number of nodes included is unlimited, and except for Figure 1 In addition to the functional nodes shown, other nodes may also be included, such as OAM devices and core network devices, and this application does not impose any restrictions on this.

[0050] Furthermore, the communication system described in the embodiments of this application is for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and does not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new communication systems, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0051] With the continuous development of communication networks, 5G networks have emerged. 5G has ushered in an era of the Internet of Everything. 5G networks not only possess characteristics such as high speed, large capacity, low latency, and high reliability, but also integrate key technologies such as network slicing and mobile edge computing (MEC). Network slicing refers to dividing a physical network into multiple end-to-end logical networks. These network slices can provide isolated and customizable network services for different vertical industries, different customers, or different services.

[0052] In current 5G networks, terminal devices can switch between multiple network slices. The typical switching process is as follows: First, the first network slice currently accessed by the target terminal is monitored based on its service requests. Second, when the network quality (e.g., signal strength) of the first network slice drops to a preset threshold #1, slice configuration data for the first network slice is sent to the target base station, enabling the target base station to configure a second network slice based on this data. Third, when the network quality of the first network slice drops to a preset threshold #2, a network switching command is sent to the target terminal, where the first threshold is greater than the second threshold, and the network switching command instructs the target terminal to switch to the second network slice. Based on this method, the terminal device can complete the switch to the second network slice. However, before triggering the switching process, the network slice to which the terminal device needs to switch (e.g., the aforementioned second network slice) must be determined to ensure the continuity of the terminal device's network slice services.

[0053] However, for terminal devices configured with dedicated slices, dedicated slice services can only be provided within the coverage area of ​​the access network device configured with that dedicated slice. When a terminal device configured with dedicated slice functionality moves to the coverage area of ​​an access network device that does not support that dedicated slice, or when the available resources of the cell to which the terminal device is to be handed over cannot meet the requirements of the dedicated slice service, the terminal device will no longer be able to support the dedicated slice service, resulting in the dedicated slice service of the terminal device not being effectively guaranteed.

[0054] Therefore, how to ensure the continuity of proprietary slicing services is a problem that urgently needs to be solved by those skilled in the art.

[0055] To address the problems existing in the prior art, this application proposes a cell determination method that can better guarantee the continuity of dedicated slice services. For example... Figure 2 As shown, the method includes:

[0056] S201, The slice operation management platform obtains the first information of at least one first cell within the target time period.

[0057] The information of the first cell includes at least one of the following: whether it supports the target slice, the number of resources to be allocated, and second information. The second information includes at least one of the following: RSRP, PRB resource utilization, and RRC connection count. The first cell is a neighboring cell whose signal strength meets the requirements among at least one neighboring cell of the terminal device.

[0058] As one possible implementation, such as Figure 3 As shown, the implementation process of S201 above can be as follows: The terminal device performs measurements based on the measurement configuration parameters, generates a measurement report, and sequentially sends the measurement report to the slice operation management platform through the source access network device and the OMC of the access network device. The measurement report includes network information of each of the multiple neighboring cells of the terminal device. This network information includes at least one of the following: signal strength, whether the target slice is supported, the number of resources to be allocated, and second information. The slice operation management platform can determine the neighboring cells with signal strength greater than or equal to a preset signal strength threshold as the first cell from the multiple neighboring cells, and filter to obtain the first information of the first cell based on the network information of the first cell.

[0059] Optionally, the above-mentioned at least one first cell can be displayed as a set, for example, the above-mentioned at least one first cell is {Cell1, Cell2, Cell3, ..., Cell7}, in which the above-mentioned at least one first cell includes 7 first cells.

[0060] S202. The slice operation management platform determines the target cell from at least one first cell based on information from at least one first cell.

[0061] As an optional implementation, the above-mentioned S202 implementation process can be as follows: the slice operation management platform can determine the number of second cells (i.e., cells supporting the target slice) in the above-mentioned at least one first cell, and perform the steps corresponding to the above-mentioned range based on the range in which the number of the second cells is located, so as to adaptively determine the target cell.

[0062] For example, if the number of the second cells is equal to the first preset threshold, the slice operation management platform determines the second cell as the target cell.

[0063] For example, if the number of the second cells is greater than the first preset threshold, the slice operation management platform determines the number of the third cells (i.e., the third cells are cells whose resources to be allocated meet the resource requirements of the target slice) in the second cells, and determines the target cells based on the method corresponding to the range of the number of the third cells.

[0064] For example, if the number of the second cells is less than the first preset threshold, the slice operation management platform determines the number of the second cells (i.e., cells that support the target slice) in the first cell, and determines the target cell based on the method corresponding to the range of the number of the second cells.

[0065] Optionally, after S202 above, such as Figure 3 As shown, the slice operation and management platform can also send configuration commands for the target slice to the target cell through the OMC of the access network equipment. Correspondingly, the target cell receives the configuration commands from the slice operation and management platform through the OMC of the access network equipment and configures the target slice based on the parameters in the configuration commands. After the target cell is configured, it sends a configuration success response to the OMC of the core network equipment and the slice operation and management platform through the OMC of the access network equipment. Then, the slice operation and management platform sequentially sends the target cell data to the terminal device through the OMC of the access network equipment and the source access network equipment, enabling the terminal device to initiate a handover process to the target cell based on the target cell data.

[0066] The above technical solution brings at least the following beneficial effects: The cell determination method provided in this application involves the slice operation management platform acquiring information on at least one first cell (i.e., a cell in the neighboring cells of the terminal device) within a target time period (including at least one of the following: whether the target slice is supported, the number of resources to be allocated, and indicator information; the indicator information includes at least one of the following: RSRP, PRB resource utilization rate, and RRC connection number), and determining the target cell from at least one first cell based on the information of the at least one first cell. Therefore, the cell determination method provided in this application can determine the target cell based on at least one of the following: whether the target slice is supported, the number of resources to be allocated, RSRP, PRB resource utilization rate, and RRC connection number, rather than relying solely on a single indicator. This can minimize the problem of target slice service interruption caused by the determined target cell not supporting the target slice or the target cell's resources not meeting the requirements, thereby better ensuring the continuity of the target service.

[0067] Optionally, the slice operation management platform needs to determine the number of second cells (i.e., first cells supporting the target slice) among at least one first cell. The process for determining the target cell differs depending on the range of the number of second cells. Based on this, the slice operation management platform can categorize the determination into three cases based on the number of second cells: Case 1: The number of second cells equals a first preset threshold. Case 2: The number of second cells is greater than the first preset threshold. Case 3: The number of second cells is less than the first preset threshold. The following explains the process for determining the target cell under each of these three cases.

[0068] Case 1: The number of second cells is equal to the first preset threshold.

[0069] In case 1, combined with Figure 2 ,like Figure 4 As shown, the above S202 can be specifically determined by the following S401.

[0070] S401, The slice operation and management platform determines the first cell that supports the target slice as the target cell.

[0071] The second cell is the first cell that supports the target slice.

[0072] For example, if the target slice is identified as A, and the slice list supported by the cell includes a slice identified as A, the slice operation and management platform can determine that the cell is the second cell.

[0073] Optionally, the slice operation management platform can set the value of the first preset threshold according to the actual situation. For example, the slice operation management platform sets the first preset threshold to 1. The above is only an exemplary description of the first preset threshold, and the first preset threshold can also be other values, which are not limited in this application.

[0074] Case 2: The number of second cells is greater than the first preset threshold.

[0075] In case 2, combined with Figure 2 ,like Figure 5 As shown, the above S202 can be specifically determined by the following S501 to S506.

[0076] S501, the slice operation management platform determines the number of third cells in the second cell.

[0077] The third cell is a cell whose number of resources to be allocated is greater than or equal to the second preset threshold.

[0078] In one optional implementation, the slice operation management platform can set the value of the second preset threshold according to the actual situation. For example, the slice operation management platform sets the second preset threshold to 20. The above is only an exemplary description of the second preset threshold, and the second preset threshold can also be other values, which are not limited in this application.

[0079] Optionally, the process by which the slice operation management platform determines the target cell differs depending on the range of the number of the third cells. Based on this, the slice operation management platform can categorize the cases into three cases based on the number of the third cells: Case 2.1: The number of third cells equals the first preset threshold. Case 2.2: The number of third cells is greater than the first preset threshold. Case 2.3: The number of third cells is less than the first preset threshold. The following describes the operations performed by the slice operation management platform under these three cases.

[0080] Case 2.1: The number of third cells is equal to the first preset threshold.

[0081] In case 2.1, combined with Figure 2 ,like Figure 5 As shown, the slice operation management platform can execute the following S502.

[0082] S502, the slice operation management platform determines the third community as the target community.

[0083] Optionally, the first preset threshold can be understood by referring to the description in the corresponding position above, and will not be repeated here.

[0084] Case 2.2: The number of third cells is greater than the first preset threshold.

[0085] In case 2.2, combined with Figure 2 ,like Figure 5 As shown, the slice operation management platform can execute the following S503 to S504.

[0086] S503, the slice operation management platform determines the target value of the third cell based on the second information of the third cell.

[0087] The target value is used to characterize the network quality of the cell.

[0088] As an optional implementation, if the second information includes PRB utilization, the implementation process of the above S503 can be as follows: the slice operation management platform can determine that the above PRB utilization is the target value.

[0089] As another optional implementation, if the second information includes the number of RRC connections, the implementation process of the above S503 can be as follows: the slice operation management platform can determine the above number of RRC connections as the target value.

[0090] As another optional implementation, when the second information includes PRB utilization and RRC connection count, the implementation process of S503 above can be as follows: the slice operation management platform can perform a weighted summation of PRB utilization and RRC connection count, and determine the value obtained by the weighted summation as the target value.

[0091] In one example, the second information mentioned above may also include RSRP.

[0092] S504. The slice operation management platform determines the third cell whose target value is greater than or equal to the third preset threshold as the target cell.

[0093] As one possible implementation, the above-mentioned S504 process can be as follows: The slice operation management platform can sort the third cells from high to low based on the target value to obtain a target sequence, and determine the third cell ranked first in the target sequence as the target cell. In this case, the target value of the third cell ranked first is a third preset threshold.

[0094] Optionally, the slice operation management platform can set the value of the third preset threshold according to the actual situation. For example, the slice operation management platform sets the third preset threshold to 500. The above is only an exemplary description of the third preset threshold, and the third preset threshold can also be other values ​​(e.g., 0.95), which is not limited in this application.
