Specifically, the use of words such as "exemplary" or "for example" is intended to present concepts in a specific way.

[0036] Before introducing in detail the method for adaptation management of communications provided in the embodiments of the present application, the implementation environment and application scenarios of the embodiments of the present application are first introduced.

[0037] First, the application scenarios of the embodiments of the present application are introduced.

[0038] With the rapid development of 5G network technology, in recent years, the integration and innovation of 5G industry applications have become an important engine leading the high-quality development of the economy. 5G technology and standards were designed with high-bandwidth, high-real-time, high-reliability and high-security communication requirements in mind. In the early stage, 5G industry applications were mainly large-bandwidth data transmission applications, such as real-time image and video applications. The third generation partnership project (3GPP) froze the second version (R16) and the third version (R17) of 5G in July 2020 and June 2022, respectively, further enhancing the ability of 5G to serve industry applications. Among them, the ultra-reliable low latency communication (URLLC) feature of 5G continues to mature, and related applications have gradually begun to enter the human-machine interface control and on-site real-time control of industrial automation control from single-link human-machine remote control. With the continuous evolution of subsequent versions of the 3GPP standard, the capabilities of more mobile network service industries will continue to increase.

[0039] The 5G network has a standardized quality of service (QoS) guarantee system in terms of service assurance. Each protocol data unit (PDU) session of the user corresponds to one or more QoS flows. Each QoS flow has a QoS flow identifier (QFI). The base station then maps the QoS flow to a radio bearer and performs corresponding scheduling. A radio bearer can correspond to multiple QoS flows. User-plane data with the same QFI in a PDU session will obtain the same forwarding and scheduling strategy.

[0040] Due to the differentiated business requirements of different 5G industry application scenarios and the uncertainty of wireless air interfaces, it is difficult for the network to meet flexible business access requirements and ensure user business experience through a set of parameters or multiple fixed sets of parameter configurations.

[0041] That is to say, since the network environment and user services are changing dynamically, and different user services have very different communication SLA requirements, fixed communication parameter configurations (such as network parameter configurations and / or service parameter configurations) are difficult to adapt to these changes, which may cause the communication performance corresponding to the user service to degrade or the communication service to be interrupted.

[0042] Therefore, it is necessary to study the dynamic collaborative perception of networks and businesses and apply it to network service assurance. The network strategies can be formulated based on the joint perception results to make the network more efficient, flexible and better match business needs. This can improve the efficiency of network resources while providing assurance for the business, thus achieving the goal of optimizing both business experience and network efficiency.

[0043] In summary, how to adapt and manage user services and communication networks has become a technical problem that needs to be solved urgently.

[0044] In order to solve the above problems, an embodiment of the present application provides a communication adaptation management method, and the communication adaptation management method provided by the embodiment of the present application is applied to the interactive scenario of the communication service. The embodiment of the present application refers to user information, service information and network information, and adapts and adjusts the user side node and / or the network side node from the perspective of at least one of the service priority, service uplink cycle and service transmission delay, so as to ensure that the SLA indicators provided by the network side node to the user side node meet the corresponding requirements, and improve the communication performance and service quality corresponding to the user service.

[0045] The implementation environment of the embodiments of the present application is introduced below.

[0046] like Figure 1As shown, it is a schematic diagram of a communication system provided in an embodiment of the present application, and the communication system may include: a user side node (such as a terminal 101) and a network side node (such as an adaptation management device 102), wherein the terminal 101 can be connected to the adaptation management device 102 by wire / wireless.

[0047] Specifically, the adaptation management device 102 pre-stores preset SLA indicators required by the terminal 101. When the SLA indicators provided by the adaptation management device 102 to the terminal 101 do not meet the preset SLA indicators, the adaptation management device 102 can be based on the user information and service information of the terminal 101, as well as the network information between the terminal 101 and the terminal 101, adapt and adjust the adaptation management device 102 itself and / or the terminal 101 from at least one of the perspectives of service priority, service uplink cycle and service transmission delay, so as to ensure that after the adaptation and adjustment, the SLA indicators provided by the adaptation management device 102 to the terminal 101 can meet the preset SLA indicators.

[0048] In some embodiments, Figure 2 As shown, the adaptation management device 102 may include: a user perception module 201, a wireless network perception module 202, a local data diversion module 203, a service perception module 204, a collaborative analysis module 205, a service network SLA demand management module 206, a network policy module 207, a combining module 208 and an information disclosure module 209.

[0049] Among them, after the terminal 101 is connected to the network service (i.e., the adaptation management device 102), the wireless network perception module 202 perceives the network information, the user perception module 201 collects user information, and sends the user information to the collaborative analysis module 205 in real time. The collaborative analysis module 205 queries the wireless network perception module 202 for the user's network information based on the user's location measurement information. The local data diversion module 203 sends the diverted data to the service perception module 204 according to the diversion principle. Other undiverted data streams are normally transmitted to the combining module 208. The service perception module 204 perceives the service status and feature data (i.e., service information) of the local data diversion module 203 in real time, and the collaborative analysis module 205 queries the service status and feature data of the user terminal from the service perception module. Based on user information, network information, and service information, the service experience and network status are predicted to generate an intelligent prediction graph. According to the service type, the service network SLA demand management module 206 is queried for the network SLA demand of the service. According to the given SLA guarantee target and the actual SLA indicators obtained from the service perception module 204, the actual deviation is analyzed and adjustment strategy suggestions are given. The network policy module 207 generates a resource scheduling optimization plan based on the predicted network status and the adjustment strategy suggestions of the collaborative analysis module 205. The information disclosure module 209 opens the prediction information and adjustment strategy suggestions generated by the collaborative analysis module 205 to the application through a unified API interface, which is used by the upper-layer application to adjust and adapt the service itself based on the network status and resources to achieve cross-layer optimization. The combining module 208 aggregates the data packets processed by the collaborative analysis module 205 with the local diversion data to complete the message redundancy processing.

[0050] It should be noted that user information includes at least one of the following: user status information, terminal status information, and location measurement information. Network information includes at least one of the following: network base station information, real-time network status information, and real-time environment status information. Service information includes at least one of the following: service type, service delay, uplink / downlink service rate, number of message transmissions, average message length, and number of abnormal messages.

[0051] Among them, network base station information includes: base station identification information, base station location information, device address information, cell identification information, and cell name information. Network status information includes: user equipment (UE) channel status information, protocol stack status information, cell-level load information, different priority service load information, cell-level uplink and downlink throughput statistics information, UE-level uplink and downlink throughput statistics information, uplink and downlink physical resource block (PRB) occupancy information. Environmental status information includes: network link quality measurement report information (such as rate, delay, spectrum resource utilization), uplink and downlink signal quality information, neighboring cell information, and switching parameter information.

[0052] In summary, the network (i.e., the adaptation management device 102) can perceive user information in real time and perceive network information based on the user location; perceive the service status and characteristic data of the user terminal in real time, perform intelligent analysis on the service data packet, dynamically identify service characteristics, and analyze service type, delay, and reliability; filter, clean and pre-process network information, user information, and service information, use AI to perform real-time data analysis, and predict service experience and network status based on historical measurement information such as location, wireless network quality, and service quality, and generate intelligent prediction graphs; query the network SLA requirements of the service, such as delay, reliability, etc., according to the service type; analyze the actual deviation according to the given SLA guarantee target and the actual SLA indicators obtained in real time, and give adjustment strategy suggestions; the network and service are respectively fine-tuned according to the adjustment strategy, so that the network and service work together to achieve service guarantee.

[0053] Moreover, by collaboratively perceiving comprehensive information and comparing it with SLA requirements, the network can obtain fine service characteristics, analyze, select and implement optimization strategies, and achieve network optimization matching service requirements. At the same time, by obtaining different information across network elements and layers, the network can comprehensively perceive or predict the status of the wireless environment and service quality, and open the perceived and predicted wireless information to the service end to assist the service in making optimization decisions. The service side negotiates with the application layer based on the status information obtained from the network side, and adjusts and adapts the service itself according to the existing network conditions, so as to achieve the best match between the service and the network and realize cross-layer optimization.

[0054] It should be noted that the embodiment of the present application does not limit the adaptation management device 102. For example, the adaptation management device 102 may be a base station, a server, or a core network element.

[0055] The server may be a single physical server or a server cluster consisting of multiple servers. Alternatively, the server cluster may be a distributed cluster. Alternatively, the server may be a cloud server. The embodiments of the present application do not limit the specific implementation of the server.

[0056] The terminal may be a mobile phone, tablet computer, desktop, laptop, handheld computer, notebook computer, ultra-mobile personal computer (UMPC), netbook, etc. with transceiver functions. The present application does not impose any special restrictions on the specific form of the terminal. It may interact with the user through one or more methods such as keyboard, touch pad, touch screen, remote control, voice interaction or handwriting device.

[0057] The base station may include various forms of base stations, such as macro base stations, micro base stations (also called small stations), relay stations, access points, etc. Specifically, it may be an access point (AP) in a wireless local area network (WLAN), a base station (Base Transceiver Station, BTS) in a global system for mobile communications (GSM) or code division multiple access (CDMA), a base station (NodeB, NB) in wideband code division multiple access (WCDMA), an evolved Node B (eNB or eNodeB) in LTE, or a relay station or access point, as well as a base station in a future sixth generation mobile communication technology (6G) network or a base station in a future evolved public land mobile network (PLMN) network, etc.

[0058] The core network elements may include various network functions, such as access and mobility management function (AMF), session management function (SMF), user plane function (UPF), policy control function (PCF), unified data management (UDM), location management function (LMF), etc.

[0059] After introducing the application scenario and implementation environment of the embodiment of the present application, the communication adaptation management method provided by the embodiment of the present application is introduced in detail in combination with the above-mentioned implementation environment.

[0060] The methods in the following embodiments can all be implemented in the above application scenarios and implementation environments. The embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0061] Figure 3 The flowchart of a communication adaptation management method provided in the embodiment of the present application is as follows. Figure 3 As shown, the method may include: S301-S304.

[0062] S301. Obtain the current SLA indicator provided by the network side node to the user side node.

[0063] As a possible implementation method, after the user-side node accesses the network-side node, the network-side node can receive and respond to the service request initiated by the user-side node, and feedback the corresponding response result to the user-side node. At the same time, the network-side node can collect the SLA indicator between the reception of the service request and the feedback of the response result to determine the current SLA indicator provided by the network-side node to the user-side node.

[0064] It should be noted that, in the embodiment of the present application, the SLA indicator may include at least one of the following: availability, response time, delay, packet loss rate, throughput, etc.

[0065] S302: Determine whether the current SLA indicator meets the preset SLA indicator.

[0066] The preset SLA indicator is used to indicate the expected standard of service quality provided by the service provider of the network side node to the customer of the user side node.

[0067] As a possible implementation, the network side node may pre-store a preset SLA indicator. Based on the preset SLA indicator, the network side node may determine the magnitude relationship between the current SLA and the preset SLA indicator, and further determine whether the current SLA indicator meets the preset SLA indicator.

[0068] For example, if the current SLA indicators include: response time of 2 seconds (s), delay of 10 milliseconds (ms), and throughput of 15 bits / second, and the preset SLA indicators include: response time of 3s, delay of 20ms, and throughput of 17 bits / second, then the current SLA indicators do not meet the preset SLA indicators.

[0069] In some embodiments, if the current SLA indicator meets the preset SLA indicator, the network side node can determine that no adaptation management is required between the user service and the communication network, and maintain the current communication state.

[0070] In other embodiments, if the current SLA indicator does not meet the preset SLA indicator, the network side node may execute S303.

[0071] S303, based on the user information and service information of the user side node, and the network information between the user side node and the network side node, simulate adjustment of at least one of the service priority, service uplink cycle and service transmission delay, and determine multiple first adjustment strategies.

[0072] The user information may include at least one of the following: user status information, terminal status information, and location measurement information.

[0073] As a possible implementation, the network side node may receive the user information actively reported by the user side node. Alternatively, the network side node may obtain the user information by accessing the user side node. Alternatively, the network side node may monitor the user side node in real time to obtain the user information.

[0074] For example, taking the example of a network side node monitoring a user side node in real time to obtain location measurement information, the network side node may use the uplink time difference of arrival (UTDOA) positioning technology to obtain location measurement information. Alternatively, the network side node may use the round trip time (RTT) positioning technology to obtain location measurement information. Alternatively, the network side node may use the angle of arrival (AOA) positioning technology to obtain location measurement information.

[0075] As a possible implementation method, the network side node can query the network information of the user side node's location based on the location measurement information obtained above, and the network information may include at least one of the following: network base station information, real-time network status information, and real-time environment status information.

[0076] Among them, network base station information includes: base station identification information, base station location information, device address information, cell identification information, and cell name information. Network status information includes: UE channel status information, protocol stack status information, cell-level load information, different priority service load information, cell-level uplink and downlink throughput statistics information, UE-level uplink and downlink throughput statistics information, and uplink and downlink PRB occupancy information. Environmental status information includes: network link quality measurement report information (such as rate, delay, spectrum resource utilization), uplink and downlink signal quality information, neighboring cell information, and switching parameter information.

[0077] As a possible implementation method, the network side node can receive the service request reported by the user side node and obtain the corresponding service information from the service request. The service information may include at least one of the following: service type, service delay, uplink / downlink service rate, number of message transmissions, average message length, and number of abnormal messages.

[0078] In an embodiment of the present application, the network side node can refer to user information, network information and service information, and simulate the adjustment of at least one of the service priority, service uplink cycle and service transmission delay by traversal, and determine multiple first adjustment strategies, where one first adjustment strategy corresponds to the first first SLA indicator.

[0079] That is to say, the network side node can refer to user information, service information and network information, and perform traversal adjustments from at least one of the perspectives of service priority, service uplink cycle and service transmission delay to obtain the adjustment effects (i.e., the first SLA indicator) corresponding to different adjustment schemes (i.e., the first adjustment strategy).

[0080] The first adjustment strategy may include at least one of the following (1)-(6):

[0081] (1) Instruct the user-side node to adjust the service priority in the service message header.

[0082] (2) Instruct the user-side node to split the initial service flow into multiple sub-service flows corresponding to different SLA indicators, where one sub-service flow corresponds to one service priority.

[0083] (3) Instruct the user-side node to adjust the service cycle.

[0084] (4) Instruct the user-side node to adjust the transmission frequency layer of the service flow (such as different frequency resource layers divided in the frequency domain).

[0085] (5) Instruct the user-side node to periodically adjust the PRB resources of the network slice.

[0086] (6) Instructing the network-side node to adjust the time for providing resource pre-scheduling to the user-side node based on the service uplink time of the user-side node.

[0087] It should be noted that, for the above (1), the network side node may instruct the user side node to adjust the service priority in the service message header from 1 to 2 (or from 3 to 1).

[0088] In other words, the user-side node processes the data header and dynamically adjusts the service priority as needed.

[0089] For the above (2), if the user service includes: service A and service B, and the response time in the SLA requirement corresponding to service A is 2ms, and the response time in the SLA requirement corresponding to service B is 2.5ms, then the network side node can instruct the user side node to split the service flow corresponding to the user service into sub-service flow A corresponding to service A and sub-service flow B corresponding to service B, and configure the service priority of sub-service flow A to 1 and the service priority of sub-service flow B to 2.

[0090] That is, the user-side node splits the service into different QoS flows according to the service flow SLA requirements, such as the splitting of video I frame flow and P frame flow, and assigns different priorities to the split QoS flows.

[0091] For the above (3), the network side node can instruct the user side node to adjust the service cycle to between 11 am and 12 am every day.

[0092] That is, the network-side node evaluates the service performance that can be met and proposes the adaptation cycle, bit rate, etc. to the user-side node to assist the service layer in making adjustment and adaptation decisions based on network capabilities. In addition, the network-side node can configure different service cycles for the services that need to be staggered in the user-side node, so that the services can be transmitted in staggered periods.

[0093] For the above (4), the network side node can plan the target frequency layer that is most suitable for carrying the service according to the characteristics of different services. When the initial access frequency layer of the terminal service is inconsistent with the planned frequency layer, the terminal can be migrated to the planned target frequency layer through precise guidance.

[0094] For (5) above, the network side node can support resource reservation configuration similar to calendar mode to achieve periodic adjustment of network slice PRB resources. By implementing the configuration of slice group guarantee resources, the following basic requirements are met:

[0095] ① The effective period can be daily, weekly or monthly;

[0096] ② The effective duration supports at least 15 minutes of granularity configuration, and the maximum does not exceed the effective period;

[0097] ③The effective start time can be configured;

[0098] ④A slice group can support at least 4 time-sensitive configuration records at the same time;

[0099] ⑤The PRB resource configuration parameters of different effective periods of the slice group can be different or the same.

[0100] For example, an enterprise slice group includes a video conferencing scenario and an enterprise office scenario, with a total of 50 PRBs. Video conferencing is conducted from 9:00 to 11:00 from Monday to Friday, with 35 PRBs allocated. The number of PRBs allocated to I frames in the message data of the video conferencing is 30, and the number of PRBs allocated to P frames is 5. Enterprise office communications are conducted from 14:00 to 16:00, with 15 PRBs allocated. Among them, the effective period is Monday to Friday, Saturday and Sunday, and the effective duration is 9:00-11:00, 14:00-16:00, Saturday and Sunday.

[0101] For the above (6), the network side node can combine the business characteristics of industry applications and the current wireless network conditions, comprehensively consider the scheduling model of the wireless base station, formulate a wireless network QoS adjustment strategy, dynamically adjust the pre-scheduling start time, and match the actual time when the business data is sent uplink, so as to further reduce the uplink data transmission delay.

[0102] In some embodiments, the network side node refers to user information, network information and service information, and simulates adjustment of at least one of the service priority, service uplink cycle and service transmission delay in a traversal manner to determine multiple first adjustment strategies. In the process, the network side node can predict the network status between the user side node and the network side node at a future moment based on the user information, service information and network information, and simulates adjustment of at least one of the service priority, service uplink cycle and service transmission delay according to the network status to determine multiple first adjustment strategies.

[0103] In other words, the network side nodes can refer to the future network status and adapt the management of user services and communication networks in advance to ensure that the SLA indicators provided by the future network side nodes to the user side nodes meet the corresponding needs and improve the communication performance and service quality corresponding to subsequent user services.

[0104] As a possible implementation method, the network side node can filter, clean and pre-process the network information, user information and service information, and use artificial intelligence (AI) to perform real-time data analysis to obtain wireless network quality and service quality information. Then, the network side node can predict the service experience and network status between the user side node and the network side node at future moments based on the location measurement information, wireless network quality and real-time service quality information in the user information, and generate an intelligent prediction map. Afterwards, the network side node can simulate and adjust at least one of the service priority, service uplink cycle and service transmission delay based on the intelligent prediction map, and determine multiple first adjustment strategies.

[0105] Among them, the network side node can analyze the business flow from the user side node, determine the internet protocol address (IP) quintuple, and analyze and extract various protocol characteristics of the business data packet based on deep packet inspection (DPI) or machine learning to identify business characteristics, including: message interval, size, upper layer protocol type, message type (such as video I frame / P frame, remote control-control instructions / task information) and other business attributes, and determine the message delay based on the message interval, and determine the reliability requirements based on the message type.
