UPF plays a significant role in 5G edge computing and network slicing technology for low latency and large bandwidth.
The 3GPP introduces a CUPS policy as an extension to the 4G core network (EPC) in the Release 14 specification, functionally decouples the Packet Gateway (PGW) and the Service Gateway (SGW), and splits the Packet Gateway (PGW) and the Service Gateway (SGW) into control planes (PGW-C and SGW-C) and user planes (PGW-U and SGW-U). The PGW-U can be distributed, so that the flexibility of traffic forwarding is improved, the equipment closer to the network edge can execute data packet processing and traffic aggregation, and the bandwidth efficiency is improved while the load of the core network is reduced.

Detailed Description
In this embodiment, the method for deploying the space-borne UPF in the space-earth integrated communication system may be applied to the space-earth integrated communication system shown in fig. 1. Referring to fig. 1, communication satellites in the heaven-earth integrated communication system include a low-orbit satellite and a high-orbit satellite, the communication satellites are connected with a ground core network, and the communication satellites are connected with user terminals such as mobile phones, tablet computers or special communication devices, so that the user terminals are connected to the ground core network. The communication satellite is configured with UPF (User Plane Function ), i.e. the communication satellite has hardware and software resources enabling UPF network element functions, enabling and disabling UPF network element functions.
Referring to fig. 2, the method for deploying a space-borne UPF in an integrated communication system includes the steps of:
s1, determining a coverage area of a communication satellite;
s2, determining the user terminal positioned in the coverage area;
s3, determining predicted business busyness of the user terminal;
s4, when the predicted traffic busyness is smaller than the busyness threshold, arranging and deploying the UPF of the communication satellite.
In performing steps S1-S4, it may be performed according to the flow shown in fig. 3. In fig. 3, the AMF (Access and Mobility Management Function ), NWDAF (Network Data Analytics Function, network data analysis function), UPF orchestration program, and the like are network elements or software/hardware modules in the communication core network. The UPF is installed on a communication satellite.
The names of AMF and NWDAF are names used in the 5G communication technology standard, and in this embodiment, only used as an example, when the star-borne UPF deployment method in the heaven-earth integrated communication system in this embodiment is applied to the communication system of other standards, the network elements involved may have other names or function combinations, but still basically belong to the technical means in this embodiment.
Referring to fig. 3, first, a session establishment request may be sent by a user terminal to a communication satellite (step 1), the communication satellite forwards the session establishment request to a terrestrial core network (step 2), specifically, an AMF in the terrestrial core network receives the session establishment request, sends information such as an ID of the user terminal and the session establishment request to an NWDAF (step 3), and triggers the NWDAF to execute steps S1 to S3. The NWDAF sends the predicted traffic busyness obtained by executing the steps S1-S3 to the UPF arrangement program (step 4), triggers the UPF arrangement program to execute the step S4, and arranges and deploys the UPF of the communication satellite (step 5). The UPF orchestration program sends instructions to orchestrate deployment to the communication satellite.
Thus, steps S1-S3 may be performed by the NWDAF and step S4 may be performed by the UPF orchestration program.
By executing the steps S1-S3, a traffic busyness threshold may be set when determining a predicted traffic busyness of a user terminal covered by the communication satellite, that is, predicting a traffic busyness degree that the user terminal will reach in a future period of time, and when the predicted traffic busyness is less than the traffic busyness threshold, predicting that a communication traffic carried by the communication satellite will be in an idle state in the future period of time, arranging and deploying a UPF of the communication satellite, for example, enabling a UPF function of the communication satellite, and realizing effects of improving session continuity, improving reliability, reducing delay, and the like through the UPF function; when the predicted traffic is busy and is greater than or equal to the traffic busyness threshold, the communication traffic carried by the communication satellite is predicted to be busy in a period of time in the future, and the UPF of the communication satellite can be not arranged and deployed, for example, the UPF function of the communication satellite is deactivated, so that the resource occupation of the communication satellite is reduced, and the communication quality of various communication traffic carried by the communication satellite is improved.
By executing the steps S1-S4, the arrangement and deployment of the UPF of the communication satellite can be realized only when the predicted busyness of the user terminal is smaller than the busyness threshold, so that the UPF function of the communication satellite can meet the quality requirement of communication business, the sinking of the UPF is realized, the occupation of communication satellite resources can be reduced when the communication business is busy, and the negative influence caused by the sinking of the UPF is reduced.
In this embodiment, when step S1, that is, the step of determining the coverage of the communication satellite is performed, the following steps may be specifically performed:
s101, acquiring ephemeris data of a communication satellite;
s102, determining the coverage range of the communication satellite according to the ephemeris data.
By performing steps S101-S102, the coverage of the communication satellite can be determined.
In this embodiment, when the step S3, that is, determining the predicted traffic busyness of the user terminal is performed, the following steps may be specifically performed:
S301A, setting a plurality of sampling moments;
S302A, sampling the traffic of a user terminal at each sampling moment to obtain a plurality of traffic sampling values;
S303A, establishing a logistic regression model;
S304A, performing logistic regression processing on the traffic sampling value by using a logistic regression model;

One specific implementation of steps S301A-S305A.
In step S301A, t is set 1 、t 2 、t 3 … …, etc.
In step S302A, at t 1 、t 2 、t 3 … … and the like, samples the traffic of the user terminal at sampling moments to obtain a plurality of traffic sampling values. For example, at sampling time t 1 Sampling, wherein the obtained traffic sampling value is x 1 The method comprises the steps of carrying out a first treatment on the surface of the At the sampling time t 2 Sampling, wherein the obtained traffic sampling value is x 3 The method comprises the steps of carrying out a first treatment on the surface of the At the sampling time t 3 Sampling, wherein the obtained traffic sampling value is x 3 ……
In step S303A, the built logistic regression model may have a shape likeWherein e is the base of the natural logarithm, x 1 、x 2 、x 3 … … et al represent input data that can be received by the logistic regression model, which can be specifically the traffic sample value, w, measured by performing step S302A 1 、w 2 、w 3 … … b et al represent model parameters of a logistic regression model, where w 1 、w 2 、w 3 … … is input data x 1 、x 2 、x 3 … …, b is a bias value, and y is an output result of the logistic regression model.
After establishing the logistic regression model, a training set and labels may be obtained, wherein trainingThe set can be the sampled value x of each traffic 1 、x 2 、x 3 … …, the tag may represent a predicted traffic busyness of a user terminal to which the communication satellite is connected in case of a training set correspondence.
The training set is used as input data of the logistic regression model, the label is used as expected output of the logistic regression model, and w in the logistic regression model is adjusted 1 、w 2 、w 3 … … b, etc., thereby training a logistic regression model. The trained logistic regression model is provided with a quantization result for receiving the traffic sampling value of the user terminal and processing the traffic sampling value, and outputting predicted traffic busyness, namely predicted busyness of the communication satellite in a future period of time.
In step S304A, the state parameters are subjected to logistic regression using a logistic regression model, and specifically, x obtained by performing step S1 may be calculated 1 、x 2 、x 3 … … and the like are input into a logistic regression model for processing.
In step S305A, the predicted traffic busyness output by the logistic regression model is obtained, specifically, after training, the output result y of the logistic regression model has a meaning of representing the predicted traffic busyness of the communication satellite, so that the logistic regression model can be applied to the traffic sampling value x input in step S304A 1 、x 2 、x 3 … … the output value y of the processing is taken as the predicted traffic busyness. The predicted traffic busyness y may quantitatively represent the busyness of the communication satellite in a future period of time, and thus the predicted traffic busyness obtained by performing steps S301A-S305A can quantitatively represent the predicted traffic busyness that the communication satellite may reach in a future period of time.
In this embodiment, when the step S3, that is, determining the predicted traffic busyness of the user terminal is performed, the following steps may be specifically performed:
S301B, when a plurality of user terminals exist, sampling is carried out in the plurality of user terminals, and a plurality of sample terminals are determined;
S302B, setting a plurality of sampling moments;
S303B, sampling the traffic of each sample terminal at each sampling moment to obtain a plurality of groups of traffic sampling values; sampling each service sampling value in the same group at the same sampling time;
S304B, determining an average value of the traffic sampling values corresponding to the same sampling time to obtain a plurality of traffic average values;
S3055B, establishing a logistic regression model;
S306B, performing logistic regression on the average value of the traffic by using a logistic regression model;
S307B, obtaining the predicted business busyness output by the logistic regression model.
Steps S301B-S307B may handle the case where a plurality of user terminals are connected to one communication satellite.
When step S301B is executed, referring to fig. 4, by detecting the number and area density of the user terminals in the coverage area of the communication satellite, an area where the number and area density of the user terminals is greater than the preset density threshold is determined as a terminal resident range, and there are more user terminals active in the terminal resident range. And uniformly setting a plurality of sampling positions in the terminal resident range, namely uniformly distributing the sampling positions in a plane space, for example, a plurality of rectangular or hexagonal sampling position lattices can be firstly generated, the sampling position lattices are infinitely repeated sampling positions, then determining the overlapping part of the sampling position lattices and the terminal resident range, and forming a plurality of uniformly distributed sampling positions in the terminal resident range by the overlapping part of the sampling position lattices.
When step S301B is executed, referring to fig. 4, a plurality of user terminals located at each sampling position are determined as sample terminals.
Step S302B is the same as step S301A, and t is set 1 、t 2 、t 3 … …, etc.
In step S303B, taking the example that the communication satellite is connected to the sample terminal a, the sample terminal B, and the sample terminal C, the following sampling process is performed:
at the sampling time t 1 Sampling the sample terminal A, and obtaining a traffic sampling value x 1A The method comprises the steps of carrying out a first treatment on the surface of the At the sampling time t 1 Sampling the sample terminal B, and obtaining a traffic sampling value x 1B The method comprises the steps of carrying out a first treatment on the surface of the At the sampling time t 1 Sampling the sample terminal C, and obtaining a traffic sampling value x 1C ；x 1A 、x 1B 、x 1C Forming a set of traffic sample values;
at the sampling time t 2 Sampling the sample terminal A, and obtaining a traffic sampling value x 2A The method comprises the steps of carrying out a first treatment on the surface of the At the sampling time t 2 Sampling the sample terminal B, and obtaining a traffic sampling value x 2B The method comprises the steps of carrying out a first treatment on the surface of the At the sampling time t 2 Sampling the sample terminal C, and obtaining a traffic sampling value x 2C ；x 2A 、x 2B 、x 2C Forming a set of traffic sample values;
at the sampling time t 3 Sampling the sample terminal A, and obtaining a traffic sampling value x 3A The method comprises the steps of carrying out a first treatment on the surface of the At the sampling time t 3 Sampling the sample terminal B, and obtaining a traffic sampling value x 3B The method comprises the steps of carrying out a first treatment on the surface of the At the sampling time t 3 Sampling the sample terminal C, and obtaining a traffic sampling value x 3C ；x 3A 、x 3B 、x 3C A set of traffic sample values is formed.
In step S304B, an average value of the traffic sampling values corresponding to the same sampling time is determined, and a plurality of traffic average values are obtained. Specifically, x 1A 、x 1B 、x 1C The set of traffic sample values are all at sample time t 1 Obtained by sampling, x is calculated 1A 、x 1B 、x 1C To obtain the traffic average x 1 ；x 2A 、x 2B 、x 2C The set of traffic sample values are all at sample time t 2 Obtained by sampling, x is calculated 2A 、x 2B 、x 2C To obtain the traffic average x 2 ；x 3A 、x 3B 、x 3C The set of traffic sample values are all at sample time t 3 Obtained by sampling, x is calculated 3A 、x 3B 、x 3C Arithmetic mean of (2) to obtainObtaining the average value x of the traffic 3 。
By executing steps S301B-S305B, in the case where a plurality of user terminals are connected to the communication satellite, a representative number of sample terminals can be selected to sample traffic according to the distribution density of the user terminals, and the sampling error of individual sample terminals can be reduced by calculating the average value of traffic, so that the obtained average value of traffic can reflect the overall traffic of the user terminals within the coverage area of the communication satellite.
The principle of the steps S305B-S307B and the steps S303A-S305A are equivalent to replacing the "traffic sample value" in the steps S303A-S305A with the "traffic average value" in the steps S305B-S307B, and the "traffic average value" in the steps S305B-S307B and the "traffic sample value" in the steps S303A-S305A belong to the same type of data, and the "traffic average value" can reflect the overall traffic of the user terminal in the coverage area of the communication satellite, so that by executing the steps S305B-S307B, the predicted traffic busyness reflecting the busyness of the communication traffic to be carried by the communication satellite in the coverage area can be obtained.
In step S4, a busyness threshold may be set, and when the predicted traffic busyness obtained by executing step S4 is smaller than the busyness threshold, the predicted traffic busyness may be considered to be sufficiently low, and the communication satellite will be in a relatively idle state in a future period of time, so as to trigger arrangement and deployment of the UPF of the communication satellite.
In this embodiment, when executing step S4, that is, the step of arranging and deploying the UPF of the communication satellite, the following steps may be specifically executed:
s401, acquiring communication session information of a user terminal;
s402, arranging and deploying UPF of the communication satellite according to the communication session information.
When step S401 is performed, the communication session information of the user terminal may be acquired in a case where the authorization of the user terminal is obtained. Specifically, an agreement may be reached with the user terminal, which is considered to be authorized when the user terminal accesses the communication satellite. Specifically, the acquired communication session information may be an individual extracted data packet from a data stream generated by a communication service such as a call, a data transmission, a call, etc. performed by the user terminal, and the extracted data packet may be selected by the user terminal, thereby reducing the risk of disclosure of the privacy information.
In step S402, the communication quality of the user terminal may be determined according to the communication session information. Specifically, the communication quality of the user terminal can be quantitatively determined by determining indexes such as data transmission speed, time delay, qos and the like according to the communication session information. For example, the larger the data transmission speed, the smaller the delay, the better the communication quality of the user terminal. Correspondingly, quality thresholds such as a data transmission speed threshold and a time delay threshold are also set, and when the data transmission speed is smaller than the data transmission speed threshold, the data transmission speed threshold can be judged to be at a lower level, namely the communication quality is at a lower level; when the time delay is greater than the time delay threshold, it can be determined that the time delay is at a higher level, i.e., the communication quality is at a lower level. And when the communication quality is lower than the quality threshold, namely the communication quality is at a lower level, inserting the UPF on a session data path of the communication session information, and finishing the arrangement and deployment of the UPF of the communication satellite.
By inserting UPF on the session data path of the communication session information, UPF sinking can be realized, the continuity of the communication session is improved, the time delay of the communication session is reduced, and the communication service quality borne by the communication satellite is improved.
In this embodiment, when executing step S4, that is, the step of arranging and deploying the UPF of the communication satellite, the following steps may be specifically executed:
s403, deleting the UPF when the predicted traffic busyness is greater than or equal to a busyness threshold or the communication quality is not lower than a quality threshold.
In step S403, when the predicted traffic busyness is greater than or equal to the busyness threshold, that is, the predicted communication satellite will be in a busyness state, or the communication quality is not lower than the quality threshold, that is, the communication quality of the communication traffic carried by the communication satellite is good enough, and no UPF optimization is required, the UPF can be deleted, and the arrangement and deployment of the UPF of the communication satellite can be completed, thereby reducing the resource occupation of the communication satellite and the load of the communication satellite.
In this embodiment, the NWDAF network element capable of executing steps S1 to S3 and the UPF arrangement program capable of executing step S4 may form a communication core network, and the AMF network element in fig. 3 may form a space-borne UPF deployment method in the space-earth integrated communication system in this embodiment may be applied to such a communication core network, and based on the principle of the space-borne UPF deployment method in the space-earth integrated communication system, when the communication core network operates, the same technical effect as the space-borne UPF deployment method in the space-earth integrated communication system may be achieved.
The same technical effects as those of the on-board UPF deployment method in the on-board communication system in the embodiment can be achieved by writing a computer program for executing the on-board UPF deployment method in the on-board communication system in the embodiment, and writing the computer program into a computer device or a storage medium, and executing the on-board UPF deployment method in the on-board communication system in the embodiment when the computer program is read out and executed.
