Converged communication refers to a new communication mode in which computer technology and traditional communication technology are integrated, i.e. a converged computer network and a traditional communication network are on one network platform, so that a plurality of application services are realized on one network platform. However, since converged communication is still in a research stage at present, there is no deployment scheme of how a base station selects a network element for processing perception information according to actual requirements.
Therefore, how the base station selects the network element for processing the perception information according to the actual requirement in the converged communication is a research hot spot.

From the above, the access network device can determine the duty ratio of the large packet service data and the duty ratio of the small packet service data in real time according to the transmission data received in the current period. Then, the access network device determines a network element for processing the perceived data according to the large packet service data duty ratio and the small packet service data duty ratio. Such as: the access network device sends transmission data to the control surface network element under the condition that the ratio of the large packet service data is smaller than that of the small packet service data, and the control surface network element processes the perception data at the moment, so that the problem of how the base station selects the network element for processing the perception data according to actual requirements in converged communication is solved.

Therefore, the control plane network element needs to analyze the transmission data to determine echo data used for sensing by the access network device and to-be-processed data reported by the terminal in the coverage area of the access network device. Then, the control surface network element sends the communication data to the next-stage network element under the condition that the data to be processed contains the communication data, so that the next-stage network element processes the communication data of the terminal after receiving the communication data; the control surface network element processes the echo data to determine a perception result under the condition that the data to be processed only comprises communication data; or the control surface network element processes the echo data and the perception data to determine the perception result under the condition that the data to be processed contains the perception data.

For example, the handheld device may be a smart phone. The in-vehicle device may be an in-vehicle navigation system. The wearable device may be a smart bracelet. The computer may be a personal digital assistant (personal digital assistant, PDA) computer, a tablet computer, or a laptop computer (laptop computer).
It should be noted that, in the data transmission provided by the embodiment of the present invention, the terminal may send the sensing data to the access network device, or may not send the sensing data, so that the data transmission has better forward network compatibility. If the terminal can send the sensing data to the access network equipment, the sensing data can be selected to be output through a control plane or a user plane. Such as: the perceived data transmission is performed on a control plane signalling physical uplink control channel (Physical Uplink Control Channel, PUCCH), a new PUCCH channel is constructed. For example, as shown in fig. 2, the new PUCCH channel may be cross-placed with the newly added sensing data (e.g., control plane sensing data) by the protocol and the control signaling of the PUCCH.
Or, performing sensing data transmission on a control plane signaling physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) to construct a new PUSCH. For example, as shown in fig. 3, the new PUSCH channel and the newly added sensing data (e.g., user plane sensing data) may be placed by crossing the control signaling of the PUSCH by the protocol.
The following describes a data processing method provided by an embodiment of the present invention with reference to a communication system shown in fig. 1, taking an access network device as a New Radio (NR) as an example.
As shown in fig. 4, the data transmission method includes the contents of the following steps S11 to S14:
s11, NR acquires the transmission data received in the current period. The transmission data at least comprises echo data for sensing and data to be processed reported by a terminal in a coverage area, wherein the data to be processed comprises communication data and/or sensing data, and the communication data comprises big packet service data and small packet service data.
In some examples, the large packet traffic and the small packet traffic are measured according to the frequency of signaling initiation, e.g., large packet traffic refers to traffic that does not require constant signaling interactions, such as video and file transfers. The packet service refers to a service requiring frequent signaling interaction, such as text in micro-signaling and heartbeat packets of APP.
In some examples, the transmission data includes 6 cases as follows:
1. the terminal uploads communication data, and the terminal does not upload sensing data, and the NR passively collects echo data for perception. In this case, the transmission data includes communication data uploaded by the terminal and echo data for perception by NR.
2. The terminal uploads communication data and perception data, and the NR passively collects echo data for perception. In this case, the transmission data includes communication data uploaded by the terminal, sensing data, and echo data for sensing by NR.
3. The terminal does not upload communication data and the terminal does not upload sensing data and the NR passively collects echo data for perception. In this case, only the echo data for which NR is used for sensing is contained in the transmission data.
4. The terminal does not upload communication data, but the terminal uploads sensing data and the NR passively collects echo data for sensing. In this case, the transmission data includes the sensing data uploaded by the terminal and echo data used for sensing by NR.
Specifically, the sensing information data acquired by the terminal includes contact sensing data and non-contact sensing data. Wherein, the sensing data of the contact type comprises body temperature, heartbeat, blood pressure and the like. The sensing data in non-contact needs the terminal to actively send a signal for sensing the surrounding environment to the surrounding environment, the signal is reflected after encountering an obstacle, at this time, the terminal can receive an echo signal returned by the signal due to emission, and the signal is obtained after statistics, for example: images, ambient temperature, ambient humidity, location information, altitude, etc.
S12, NR determines the large packet service data duty ratio and the small packet service data duty ratio under the condition that the data to be processed contains communication data.
In some examples, the total amount of traffic data generated by different traffic varies. Therefore, the traffic data generated by the large packet traffic and the traffic data generated by the small packet traffic, which are included in the communication data, need to be determined, may be referred to as large packet traffic data. Wherein the packet service data duty ratio is equal to
Figure BDA0003355528400000121
The duty ratio of the large packet service data is equal to 1-P Packet traffic data duty cycle 。
Wherein T is Total amount of packet traffic data Refers to the sum of service data generated by all packet services in communication data, T Total amount of large packet service data Refers to the sum of service data generated by all large packet services in communication data, P Packet traffic data duty cycle Representing packet traffic data duty cycle.
S13, NR determines the target network element for processing the transmission data according to the large packet service data duty ratio and the small packet service data duty ratio.
S14, the NR sends the transmission data to the target network element.
From the above, according to the data transmission method provided by the present invention, the NR can determine the duty ratio of the large packet service data and the duty ratio of the small packet service data in real time according to the transmission data received in the current period. Then, NR determines network element for processing perceived data according to the large packet service data duty ratio and small packet service data duty ratio. Such as: and when the NR determines that the duty ratio of the large packet service data is smaller than that of the small packet service data, transmitting transmission data to the control plane network element, and processing the perception data by the control plane network element at the moment, thereby solving the problem of how to select the network element for processing the perception data according to the actual requirement by the base station in converged communication.
In some implementations, the target network element includes a control plane network element; referring to fig. 4, as shown in fig. 5, S13 may be specifically implemented as S130 described below, and S14 may be specifically implemented as S140 described below.
S130, NR determines the target network element for processing the transmission data as the control surface network element under the condition that the large packet service data duty ratio is smaller than the small packet service data duty ratio.
And S140, the NR sends transmission data to the control plane network element.
In some examples, the computing resources configured by the control plane network element are smaller than the computing resources configured by the user plane network element. Therefore, the perceived data can be processed by the control plane network element under the condition of smaller computing resource requirements. Such as: in the case where the large packet traffic data is smaller than the small packet traffic data, this means that less computational resources are required at this time. Thus, the NR determines the target network element that handles the transmission of data as the control plane network element.
In some implementations, the target network element includes a user plane network element; referring to fig. 4, as shown in fig. 6, S13 may be specifically realized by S131 described below, and S14 may be specifically realized by S141 described below.
S131, NR determines the target network element for processing the transmission data as the user plane network element under the condition that the large packet service data duty ratio is larger than or equal to the small packet service data duty ratio.
S141, NR sends transmission data to user plane network element.
In some examples, the computing resources configured by the control plane network element are smaller than the computing resources configured by the user plane network element. Therefore, under the condition of high demand for computing resources, the perceived data can be processed through the user plane network element. Such as: when the large packet service data duty ratio is greater than or equal to the small packet service data duty ratio, the calculation resource needed at the moment is more. Therefore, the NR determines that the target network element that processes the transmission data is the user plane network element.
In some implementations, the communication data further includes a quality of service (Quality of Service, qoS) priority; referring to fig. 4, as shown in fig. 7, S14 may be specifically implemented by S142 described below, and the data transmission method provided in the embodiment of the present invention further includes S15.
S15, NR determines a target terminal with Qos priority higher than or equal to target priority in a coverage area under the condition that the duty ratio of large packet service data is higher than or equal to the duty ratio of small packet service data and the ratio of the actual data volume of the transmission data to the rated data volume is higher than a preset ratio.
In some examples, in combination with the example given in S130 above, the NR determines that the large packet service data duty ratio is greater than or equal to the small packet service data duty ratio, and if the ratio of the actual data amount of the transmission data to the rated data amount is greater than the preset ratio, it indicates that the remaining computing resources of the current user plane network element are less, so as to ensure the processing progress of the perceived data. Therefore, the NR needs to screen the perceived data to be processed, for example, according to the Qos priority of the terminal, the target terminal with the Qos priority greater than or equal to the target priority is screened, so that the total data amount of perceived data to be processed by the user plane network element can be reduced, and the user experience is ensured.
Specifically, the rated data size is the rated maximum data size of the interface between the access network device and the user plane network element. Such as: in combination with the communication system shown in fig. 1, the access network device establishes communication connection with the user plane network element through the N3 interface, and at this time, the rated maximum data size of the N3 interface is the rated data size.
Illustratively, the preset ratio may be 90%.
And S142, the NR sends echo data and reported pending data of the target terminal to the user plane network element.
It should be noted that, since the NR determines that the packet service data duty ratio is greater than or equal to the packet service data duty ratio, the NR needs to screen the perceived data to be processed, for example, screen the target terminal with Qos priority greater than or equal to the target priority according to Qos priority of the terminal. At this time, in the process of sending transmission data to the user plane network element, the NR only sends part of the transmission data, such as echo data and reported data to be processed of the target terminal. Therefore, the transmission data only comprises the echo data and the perception data reported by the target terminal, so that the total data quantity of the perception data which needs to be processed by the user plane network element can be reduced, and the user experience is ensured.
The following describes a data processing method provided by the embodiment of the present invention, taking a control plane network element as an AMF as an example, in conjunction with the communication system shown in fig. 1.
As shown in fig. 5, the data transmission method includes the contents of the following steps S21 to S24:
s21, AMF receives the transmission data sent by NR.
In some examples, the AMF stores the received transmission data in real time to ensure subsequent use.
S22, AMF determines echo data for sensing NR in the transmission data and data to be processed reported by a terminal in the coverage area of NR; the data to be processed comprises communication data and/or perception data, and the communication data comprises big package service data and small package service data.
In some examples, the transmission data includes echo data for sensing and pending data reported by terminals within the coverage area. There are also differences in the manner in which AMF is processed for different data. Therefore, after the AMF receives the transmission data sent by the access network device, the distinction needs to be made between the echo data used for sensing in the transmission data and the data to be processed reported by the terminal in the coverage area of the access network device, so as to determine the echo data used for sensing in the transmission data and the data to be processed reported by the terminal in the coverage area of the access network device. And then, the AMF sends the communication data in the transmission data to the next-stage network element.
In some examples, the echo data and the data to be processed correspond to different data identifications. And the AMF determines echo data and data to be processed according to the data identification. Or the echo data and the data to be processed are transmitted to the AMF through data packets with different formats, and the AMF can determine the echo data and the data to be processed according to the formats of the data packets.
S23, the AMF sends the communication data to the next-stage network element under the condition that the data to be processed comprises the communication data.
In some examples, the procedure of the AMF for processing the communication data (authentication, mobility management, etc.) is the same as the procedure of the AMF for processing the communication data in the prior art, and will not be described herein.
S24, under the condition that the data to be processed only comprise communication data, the AMF processes the echo data to determine a perception result. Or, if the data to be processed only contains the sensing data, the AMF processes the echo data and the sensing data to determine the sensing result.
In some examples, the AMF analyzes the collected sensing data within a period of time, may be based on a time point or may be based on superposition of multiple time point data, and performs operations such as sensing, positioning, imaging and the like on the superposed sensing data, so as to determine a sensing result.
Such as: the echo data and the perception data contain received signal strength indicators (Received Signal Strength Indication, RSSI). At this time, in the case where the data to be processed contains only communication data, the AMF may perform processing according to the echo data to determine the position of the terminal or NR. Or the AMF processes the echo data and the perception data to obtain the position of the terminal or NR when the to-be-processed data contains the perception data.
Specifically, the procedure for determining the location of the terminal or NR is as follows:
the RSSI of the signal receiving end is inversely proportional to the distance between the receiving end and the transmitting end, so that the distance can be estimated through the signal strength and further used for positioning calculation. By establishing a related description model for the path loss, the distance relation between the received signal power and the receiving and transmitting ends in different scenes can be accurately described.
Figure BDA0003355528400000161
Wherein P is r (d) Represents the received signal power, P (d) 0 ) Represents the distance d 0 The standard power parameter in the time, eta represents the loss coefficient and epsilon represents the environmental impact factor.
Then, the position of the terminal or NR is determined based on the obtained signal power.
It should be noted that, the positioning method based on RSSI is usually used in the near field communication positioning scenarios such as bluetooth and wifi, and the loss coefficient of the signal transmission path is different in different environmental scenarios, and a unified model cannot be built to describe all scenarios, and the model may be invalid due to the change of the scenarios.
From the above, according to the data transmission method provided by the present invention, after the NR determines that the AMF processes the perceived data, the NR sends the transmission data to the AMF. After the AMF receives the transmission data sent by the NR, there is a difference in the processing mode due to different data needs. Therefore, the AMF needs to parse the transmission data to determine echo data for NR to perceive and data to be processed reported by the terminal in the coverage area of the NR. Then, the AMF sends the communication data to the next-stage network element under the condition that the data to be processed contains the communication data, so that the next-stage network element processes the communication data of the terminal after receiving the communication data; the AMF processes the echo data to determine a perception result under the condition that the data to be processed only contains communication data; or, if the data to be processed contains the sensing data, the AMF processes the echo data and the sensing data to determine a sensing result. The method solves the problem of how to select the network element for processing the perception data according to the actual demand by the base station in the converged communication.
The following describes a data processing method provided by an embodiment of the present invention, taking a control plane network element as a UPF as an example in connection with the communication system shown in fig. 1.
As shown in fig. 6, the data transmission method includes the contents of the following steps S31 to S34:
s31, the UPF receives transmission data sent by NR.
In some examples, the UPF stores the received transmission data in real time to ensure subsequent use.
S32, UPF determines echo data for sensing by NR in the transmission data and data to be processed reported by a terminal in the coverage area of NR. The data to be processed comprises communication data and/or perception data, and the communication data comprises big package service data and small package service data.
In some examples, the transmission data includes echo data for sensing and pending data reported by terminals within the coverage area. There are also differences in the way the UPF is handled for different data. Therefore, after receiving the transmission data sent by the access network device, the UPF needs to distinguish the echo data used for sensing in the transmission data from the data to be processed reported by the terminal in the coverage area of the access network device, so as to determine the echo data used for sensing in the transmission data and the data to be processed reported by the terminal in the coverage area of the access network device. And then, the UPF sends the communication data to the data network element under the condition that the data to be processed contains the communication data.
In some examples, the echo data and the data to be processed correspond to different data identifications. And the UPF determines echo data and data to be processed according to the data identification. Or the echo data and the data to be processed are transmitted to the UPF through data packets with different formats, and the UPF can determine the echo data and the data to be processed according to the formats of the data packets.
And S33, the UPF sends the communication data to the data network element under the condition that the data to be processed contains the communication data.
S34, processing the echo data by the UPF under the condition that the data to be processed only comprises communication data so as to determine a perception result; or, if the data to be processed only contains the sensing data, the UPF processes the echo data and the sensing data to determine the sensing result.
In some examples, the UPF analyzes the collected sensory data over a period of time, may be based on a time point or may be based on a superposition of multiple time point data, and performs operations such as sensing, positioning, imaging, etc. on the superposed sensory data, so as to determine a sensing result.
Specifically, in combination with the example given in S24 above, the processing procedure for processing the echo data to determine the sensing result when the data to be processed includes only the communication data is similar to the processing procedure for processing the echo data to determine the sensing result when the AMF includes only the communication data when the data to be processed includes only the communication data, which is not described herein.
Specifically, in combination with the example given in S24 above, the processing procedure for processing the echo data and the sensing data to determine the sensing result when the data to be processed includes the sensing data by the UPF is similar to the processing procedure for processing the echo data and the sensing data to determine the sensing result when the data to be processed includes the sensing data by the AMF, which is not described herein.
From the above, according to the data transmission method provided by the present invention, after the NR determines that the UPF processes the perceived data, the NR sends the transmission data to the UPF. After the UPF receives the transmission data sent by the NR, the processing modes are different due to different data. Therefore, the UPF needs to parse the transmission data to determine echo data for sensing by the NR and communication data and sensing data reported by terminals within the coverage area of the NR. And then, the UPF sends the communication data to the data network element under the condition that the data to be processed contains the communication data. Processing the echo data by the UPF under the condition that the data to be processed only comprises communication data so as to determine a perception result; or if the data to be processed contains the perception data, the UPF processes the echo data and the perception data to determine a perception result. The method solves the problem of how to select the network element for processing the perception data according to the actual demand by the base station in the converged communication.
