Description

Technical Field

[0001] This application relates to the field of communication networks, and more particularly to a communication method, communication device, and electronic device. Background Technology

[0002] Wireless access network (WAN) devices are access devices for 5G networks. They are used to connect terminal devices to the communication network provided by the communication system. At the same time, WAN devices execute the service policies of various applications issued by the core network elements so that the terminal devices connected to the communication network can enjoy the services of various applications.

[0003] Radio access network (RAN) devices need to dynamically adjust their service data processing strategies for terminal devices under different network conditions and when handling different services. Currently, after receiving a policy from a core network element, the RAN device first performs policy preparation. Then, the RAN device requests the execution of this policy from the core network element. Only after the core network element confirms the request can the RAN device process service data based on the policy.

[0004] However, the number of core network elements in a communication system is far less than the number of wireless access network devices, and the physical distance between core network elements and wireless access network devices is far. The above processing method introduces additional control and transmission delays, resulting in low policy configuration efficiency. Summary of the Invention

[0047] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0048] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0049] The wireless access network equipment in this application embodiment may be an evolved wireless access network equipment (eNB or eNodeB) of the LTE system, or a next-generation wireless access network equipment (gNB) of the worldwide interoperability for microwave access (WiMAX) communication system, the 5th generation (5G) communication system or the new radio (NR) system, or a wireless access network equipment of future communication systems (such as the 6th generation mobile communication system), etc. This application embodiment is not limited.

[0050] In this embodiment, the core network element can be a Policy Control Function (PCF) element. The PCF element supports a unified policy framework to manage network behavior and provides policy rules to network entities (such as radio access network devices) for enforcement. Optionally, the core network element involved in this embodiment can also be a newly added element in the core network, specifically used to execute the method of this embodiment, or other core network elements in a future communication system.

[0051] In this application, the terminal device can refer to user equipment (UE), access terminal device, user unit, user station, mobile station, mobile station, remote station, remote terminal device, mobile device, user terminal device, terminal device, wireless communication device, user agent, or user device. The terminal device can also be a cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA), handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, vehicle-mounted device, wearable device, terminal device in a future 5G network, or terminal device in a future evolved satellite communication system (public land mobile network, PLMN), etc. This application does not limit the scope of the terminal device to these specific types.

[0052] In practical applications, the policy configuration of wireless access network (WLAN) devices is issued by the core network elements. Once configured, the WLAN devices operate according to this policy configuration for an extended period. However, in reality, WLAN devices need to dynamically adjust their processing strategies for terminal device service data under different network conditions and service requirements. For example, during operation, WLAN devices may experience data traffic overload. In such cases, the WLAN devices need to adjust their processing strategies for terminal device service data based on the current service data volume of the terminal devices and the current resource utilization rate of the WLAN devices.

[0053] Figure 1 This is a schematic diagram illustrating a communication method between a wireless access network device and a core network element in existing technology. For example... Figure 1 As shown, in the prior art, after receiving a policy from the core network device, the wireless access network device first performs policy preparation. Then, the wireless access network device requests the execution of this policy from the core network element. Only after the core network element confirms the request can the wireless access network device process service data based on the policy.

[0054] However, in communication systems, the number of core network elements is far less than the number of radio access network devices, and the physical distance between core network elements and radio access network devices is considerable. The latency generated during communication between radio access network devices and core network elements affects the real-time performance of dynamic policy adjustments. In other words, this approach introduces additional control and transmission latency, resulting in lower policy configuration efficiency.

[0055] Therefore, this patent proposes a communication method in which the wireless access network device receives a policy from the core network device, stores the policy on the wireless access network device, and selects the corresponding policy and executes it directly based on the current service data volume of the terminal device and the current resource utilization rate of the wireless access network device. This method can realize the dynamic policy adjustment of the wireless access network device without introducing additional control delay and transmission delay.

[0056] The method described in this application can be applied to any communication system that needs to dynamically issue policies to wireless access network devices, including but not limited to 5G communication systems.

[0057] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems will be described in detail below with reference to specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0058] Figure 2 This is a schematic diagram illustrating a communication method provided in an embodiment of this application. Figure 2As shown, the method may include the following steps:

[0059] S201. The core network element generates a candidate policy set for the radio access network device. The candidate policy set includes at least one candidate policy.

[0060] The candidate policy set includes at least one candidate policy, which is a strategy used by the radio access network (RAN) device to process service data. The candidate policies are related to the objects for which the RAN device needs policy adjustments. For example, when the RAN device needs to make adjustments due to traffic overload, the candidate policy set is a collection of relevant candidate policies for resolving the traffic overload.

[0061] In some embodiments, before receiving the first information sent by the core network element, the radio access network device may send an acquisition request to the core network to request the core network element to allocate a candidate policy set. Alternatively, the core network element may periodically send the first information to the radio access network device according to a pre-set period. No specific requirements are specified here.

[0062] Since radio access network (RAN) devices can only execute policies issued by core network elements, core network elements need to generate candidate policy sets for the corresponding RAN devices and issue them to the corresponding RAN devices. Core network elements can generate candidate policy sets based on the acquisition requests sent by RAN devices and specify the details of the candidate policies.

[0063] S202, The core network element sends the first information to the wireless access network device.

[0064] Accordingly, the wireless access network device receives the first information sent by the core network element. Simultaneously, the wireless access network device stores the first information for retrieval at any time.

[0065] For example, core network elements can send first information to radio access network devices using existing control signaling. That is, the first information can be a newly added field in the existing control signaling or a blank field. As another example, core network elements can send first information to radio access network devices using new control signaling.

[0066] In some embodiments, after receiving the first information sent by the core network element, the radio access network device sends a first response message to the core network element. The first response message indicates that the radio access network device has received the candidate policy set. Accordingly, the core network element receives the first response message.

[0067] It should be noted that the radio access network (RAN) device can send the first response message to the core network element at any time after receiving the first information sent by the core network element. For example, the RAN device may send the first response message to the core network element before determining the target policy from the candidate policy set. Alternatively, it may send the first response message to the core network element after determining the target policy from the candidate policy set, but before processing the service data from terminal devices within the coverage area.

[0068] S203. The wireless access network device determines the target policy from the candidate policy set based on the current service data volume of the terminal devices within the coverage area and the current resource utilization rate of the wireless access network device.

[0069] After receiving the first information from the core network element, the radio access network (RAN) device obtains the current service data volume of terminal devices within its coverage area and the current resource utilization rate of the RAN device. Based on the current service data volume of terminal devices within its coverage area, the current resource utilization rate of the RAN device, and the selection conditions corresponding to each candidate strategy, it determines the target strategy from the candidate strategy set. The selection conditions for each candidate strategy are either preset or indicated by the first information. Each selection condition corresponds to one strategy in the candidate strategy set.

[0070] The selection conditions mentioned here can be pre-configured on the radio access network (RAN) device side, or they can be sent to the RAN device by the core network element through other information. Alternatively, they can be the selection conditions corresponding to each candidate policy generated by the core network element when generating the candidate policy set for the RAN device, and sent to the RAN device along with the first information. That is, the first information is also used to indicate the selection conditions corresponding to each candidate policy.

[0071] Radio access network (RAN) devices receive candidate policy sets from core network elements and can also obtain information such as the current service data volume of terminal devices within their coverage area and the current resource utilization rate of the RAN devices. However, when RAN devices need to select the corresponding target policy from the candidate policy set based on this information, selection conditions must be introduced to link the policy with the information. Furthermore, since RAN devices themselves cannot formulate relevant policies or rules, core network elements must generate selection conditions corresponding to the candidate policies while generating the candidate policies.

[0072] Exemplarily, the core network element sets different thresholds for the current service data volume of the terminal devices within the coverage range of the radio access network device and the current resource utilization rate of the radio access network device. For example, the threshold for the current service data volume of the terminal devices is M, and the threshold for the current resource utilization rate of the radio access network device is N. Then, when the current service data volume of the terminal devices obtained by the radio access network device is greater than M, taking this as a selection condition, the radio access network device selects the corresponding target policy. Or when the current resource utilization rate of the radio access network device is greater than N, taking this as a selection condition, the radio access network device selects the corresponding target policy. Or, when the current service data volume of the terminal devices obtained by the radio access network device is greater than M and at the same time the current resource utilization rate of the radio access network device is greater than N, taking this as a selection condition, the radio access network device selects the corresponding target policy.

[0073] Exemplarily, for the selection condition, a certain algorithm can be set. For example, the current service data volume of the terminal devices and the current resource utilization rate of the radio access network device are used as parameters for input, and according to the selection condition, it is judged which target policy should be selected, and the target policy is used as the output. For example, the threshold for the current service data volume of the terminal devices is M, and the threshold for the current resource utilization rate of the radio access network device is N. Accordingly, there are several selection conditions as follows: Condition 1: Service data volume > M & Utilization rate > N; Condition 2: Real-time traffic > M & Utilization rate < N; Condition 3: Real-time traffic < M & Utilization rate > N; Condition 4: Real-time traffic < M & Utilization rate < N.

[0074] In some embodiments, each candidate policy in the candidate policy set includes a processing method for service data, or includes a processing method for service data and the priority of service data.

[0075] Exemplarily, the processing method refers to the processing policy of the radio access network device for each service data, including retention, forwarding, discarding, etc. The processing method of service data can be identified by different fields. For example, if the field of service data A is "forward", the radio access network device forwards service data A, and if the field of service data B is "discard", the radio access network device discards service data B. This can reduce the number of service data that the radio access network device needs to process, thereby avoiding traffic overload of the radio access network device.

[0076] Priority refers to how wireless access network (WLAN) devices process each piece of service data according to its priority. Service data priorities are categorized into three levels: high, medium, and low, which can be determined based on actual communication needs. Service data priorities can be identified by different characters. For example, if the field for service data C is "high," the field for service data D is "medium," and the field for service data E is "low," then the WLAN device will process service data in the order of C, D, and E. This prioritizes higher-priority service data, improving the efficiency of service data processing in the WLAN device.

[0077] For example, the candidate policy set includes the following policies: Policy 1: Discard 30% of the service data and set the priority of the remaining service data to low; Policy 2: Discard 10% of the service data and set the priority of the remaining service data to medium; Policy 3: Do not discard service data and set the priority of all service data to high. In this case, when condition 1 above occurs, the radio access network device executes policy 1; when condition 2 or condition 3 occurs, the radio access network device executes policy 2; when condition 4 occurs, the radio access network device executes policy 3.

[0078] The above only provides several implementation methods for selection conditions and corresponding candidate strategies. Core network elements can formulate appropriate candidate strategy sets and selection conditions based on the acquisition requests sent by the radio access network devices, or by obtaining the current or future operating status or working conditions of the radio access network devices. For example, they can combine the above candidate strategy sets and selection conditions, etc., but no specific requirements are made here.

[0079] S204. The wireless access network equipment processes service data from terminal devices within the coverage area according to the target policy.

[0080] The wireless access network equipment adjusts the way it processes service data of terminal devices within its coverage area based on the target policy. Since the target policy is selected based on the current operation and working status of the wireless access network equipment, the amount of service data processed by the wireless access network equipment can be reduced through policy adjustment, thereby reducing the possibility of traffic overload on the wireless access network equipment.

[0081] Taking the target policy, which includes the processing method and priority of service data, as an example, the wireless access network device processes the service data from terminal devices within the coverage area according to the processing method, and adds the priority included in the target policy to the service data to be sent to the core network.

[0082] For example, if data A has the field "Retain + High", data B has the field "Drop + Medium", and data C has the field "Forward + Low", then the radio access network (RAN) device will process the data in the following order: first, process data A; then, discard data B; and finally, forward data C. Implementing this strategy reduces the likelihood of RAN device downtime because forwarding data consumes more internal resources than discarding it. Furthermore, this strategy reduces the processing load on subsequent RAN devices and the possibility of link congestion. Combining processing methods with priorities further optimizes the data processing efficiency of the RAN device.

[0083] In some embodiments, the target policy further includes a proportional policy. A proportional policy refers to dividing service data proportionally, processing some data using a processing method and applying a priority policy to others. For example, for service data A, B, C, D, and E, if the proportional policy is to process the first 40% and apply a priority policy to the remaining 60%, then the radio access network device will retain, forward, or discard service data A and B, and process service data C, D, and E according to their priorities.

[0084] It should be noted that the above only provides a few possible implementation methods for processing, priority, and proportion strategies. In specific implementation, these strategies can be combined and configured, and no specific requirements are made here.

[0085] In the communication method of this application embodiment, the wireless access network device receives first information sent by the core network and stores it inside the wireless access network device. At the same time, the wireless access network device determines the target strategy from the candidate strategy set of the first information based on its current working status or operating status, such as the current service data volume of terminal devices within the coverage area and the current resource utilization rate of the wireless access network device. This optimizes the operating status of the wireless access network device and avoids the wireless access network device from experiencing traffic overload, which would affect the use of each terminal device within the coverage area.

[0086] Figure 3 This is a schematic diagram of a communication method provided in an embodiment of this application. In some embodiments, after the wireless access network device processes the service data from the terminal device within its coverage area, that is, after step S204, the following steps may also be performed:

[0087] S301. The wireless access network device sends the second information to the core network element.

[0088] Accordingly, the core network elements receive this second information.

[0089] The second information is used to indicate the target policy. That is, after determining the target policy to be executed, the radio access network (RAN) device feeds back the target policy to the core network element, or simultaneously feeds back the current service data volume of terminal devices within the RAN device's current coverage area, as well as the current resource utilization rate of the RAN device. The core network element can then understand the current operating status or working condition of the RAN device, providing a basis for updating the candidate policy set. It should be noted that the RAN device can send the second information to the core network element after executing the target policy, or simultaneously. Alternatively, the RAN device can send the second information to the core network element when the service data volume is low.

[0090] In some embodiments, after receiving the second information sent by the radio access network device, the core network element performs the following steps:

[0091] S302, Core network elements send third information to wireless access network devices.

[0092] Accordingly, the wireless access network device receives this third information.

[0093] The third piece of information is used to indicate the updated candidate policy set. For example, based on the second piece of information, the core network element confirms the current service data volume of the radio access network device and the current resource utilization rate of the radio access network device, and updates the candidate policy set accordingly, and issues candidate policies that are more suitable for the current or future operating state of the radio access network device, including but not limited to updating processing methods, priorities and proportion policies.

[0094] In some embodiments, after receiving third information sent by a core network element, the wireless access network device performs the following steps:

[0095] S303. The wireless access network device sends a second response message to the core network element.

[0096] The second response message is used to indicate that the radio access network device has received the updated set of candidate policies.

[0097] The above describes the communication method steps of the embodiments of this application. In practical applications, wireless access network devices and core network elements can determine which specific steps to implement and the order of implementation as needed.

[0098] The above are embodiments of the method of this application. The communication device and wireless access network equipment provided in the embodiments of this application will be described below.

[0099] Figure 4 This is a schematic diagram of a communication device provided in an embodiment of this application. Figure 4As shown, the communication device includes a receiving module 41 and a processing module 42. Optionally, the communication device may also include a transmitting module (not shown in the figure).

[0100] The receiving module 41 is used to receive first information sent by the core network element. The first information is used to indicate a candidate policy set, which includes at least one candidate policy.

[0101] The processing module 42 is used to determine the target policy from the candidate policy set based on the current service data volume of the terminal devices within the coverage area and the current resource utilization rate of the wireless access network devices, and to process the service data from the terminal devices within the coverage area according to the target policy.

[0102] One possible implementation is that the processing module 51 is specifically used to: determine the target strategy from the candidate strategy set based on the current service data volume of the terminal devices within the coverage area, the current resource utilization rate of the wireless access network devices, and the selection conditions corresponding to each candidate strategy; wherein the selection conditions corresponding to each candidate strategy are preset or indicated by the first information.

[0103] For example, the target policy includes: the processing method of the service data and the priority of the service data; the processing module 42 processes the service data from the terminal devices within the coverage area according to the processing method, and adds the priority included in the target policy to the service data to be sent to the core network.

[0104] In one possible implementation, the receiving module 41 is specifically configured to: send an acquisition request to the core network via the sending module, the acquisition request being used to request the core network elements to allocate a candidate policy set; the receiving module 41 receives the first information sent by the core network elements, and then the sending module sends a first response message to the core network elements, the first response message being used to indicate that the radio access network device has received the candidate policy set.

[0105] For example, the sending module sends second information to the core network element, the second information indicating the target policy. The receiving module 41 receives third information sent by the core network element, the third information indicating the updated candidate policy set.

[0106] For example, the sending module sends a second response message to the core network element, the second response message being used to indicate that the radio access network device has received the updated candidate policy set.

[0107] The communication device provided in this application can perform the communication method actions in the above method embodiments. Its implementation principle and technical effect are similar, and will not be described again here.

[0108] Figure 5 This is a schematic diagram of a communication device provided in an embodiment of this application. Figure 5 As shown, the communication device includes a processing module 51 and a transmitting module 52. Optionally, the communication device may also include a receiving module (not shown in the figure).

[0109] Processing module 51 is used to generate a candidate policy set for wireless access network devices, the candidate policy set including at least one candidate policy.

[0110] The sending module 52 is used to send first information to the wireless access network device. The first information is used to indicate a candidate policy set so that the wireless access network device can determine a target policy from the candidate policy set based on the current service data volume of the terminal devices within the coverage area and the current resource utilization rate of the wireless access network device, and process the service data from the terminal devices within the coverage area according to the target policy.

[0111] One possible implementation is that the processing module 51 is specifically used to: generate a set of candidate policies for the wireless access network device, and selection conditions corresponding to each candidate policy; the first information is also used to indicate the selection conditions corresponding to each candidate policy.

[0112] One possible implementation is that the sending module 52 is specifically used to: before sending the first information to the radio access network device, the receiving module receives the acquisition request sent by the radio access network device, the acquisition request being used to request the core network element to allocate a candidate strategy set.

[0113] For example, after the sending module 52 sends the first information to the wireless access network device, the receiving module receives the first response message sent by the wireless access network device. The first response message is used to indicate that the wireless access network device has received the candidate policy set.

[0114] For example, after the sending module 52 sends the first information to the wireless access network device, the receiving module receives the second information sent by the wireless access network device, the second information being used to indicate the target policy.

[0115] For example, the sending module 52 sends third information to the wireless access network device, the third information being used to indicate the updated candidate policy set; the receiving module receives a second response message sent by the wireless access network device, the second response message being used to indicate that the wireless access network device has received the updated candidate policy set.

[0121] The electronic device 600 can communicate and interact with external devices through the communication interface 603.

[0122] In practical implementation, if the communication interface 603, memory 602, and processor 601 are implemented independently, they can be interconnected via a bus to complete communication. The bus can be an Industry Standard Architecture (ISA) bus, a Peripheral Component Interconnect (PCI) bus, or an Extended Industry Standard Architecture (EISA) bus, etc. Buses can be categorized as address buses, data buses, control buses, etc., but this does not imply that there is only one bus or one type of bus.

[0123] Optionally, in a specific implementation, if the communication interface 603, memory 602, and processor 601 are integrated on a single chip, then the communication interface 603, memory 602, and processor 601 can communicate through an internal interface.

[0124] This application also provides a computer-readable storage medium, which may include various media capable of storing program code, such as a USB flash drive, a portable hard drive, a read-only memory (ROM), a random access memory (RAM), a magnetic disk, or an optical disk. Specifically, the computer-readable storage medium stores program instructions, which are used for the communication methods in the above embodiments.

[0125] This application also provides a computer program product including executable instructions stored in a readable storage medium. At least one processor of an electronic device 600 can read the executable instructions from the readable storage medium, and the at least one processor executes the executable instructions to cause the electronic device 600 to implement the communication methods provided in the various embodiments described above.
