Taking an intelligent production line as an example, different production lines can communicate through a 5G side uplink so as to realize interaction of production behaviors. For example, because the production efficiency of different production lines is different, the order congestion degree on different production lines is also different, so that because of the synchronization of the production speeds, the order can be flexibly allocated between different production lines through the side-link communication, and the order congestion caused by too centralizing the order to certain production lines is avoided, and the production efficiency is influenced.

Referring to fig. 2, an embodiment of the present application provides a communication system, including: network equipment and terminals.

The network device may provide the AF in the above 5GS with a production service, and the specific type of the production service is not limited.

The terminal may be a control terminal or a communication terminal of the production line. Communication of the AF with the production line is understood to be communication between the AF and a control terminal or communication terminal of the production line. The production lines have M production lines, M is an integer greater than 1, PC5 connection is established between the M production lines, namely, side line communication is carried out through a side line link, and side line resources used by the side line communication can be allocated in advance by RAN equipment accessed by the M production lines respectively.

In the communication system, in the case that the AF-managed production line and the AF are distributed in different public land mobile networks (Public Land Mobile Network, PLMN), for example, the AF is located in a first PLMN, M production lines access to a second PLMN, and the second PLMN is a visited public land mobile network (Visited Public Land Mobile Network, VPLMN) of M production lines, and the first PLMN is a home public land mobile network (Home Public Land Mobile Network, HPLMN) of M production lines, so that the AF of the HPLMN can obtain the production state change condition of each of the M production lines within a specified period from the VPLMN by subscribing to an open service. On the basis, AF analyzes the production state change condition of each M production lines in a specified time period through a large module so as to estimate the future production speed change of the ith production line in the M production lines, instruct VPLMN to adjust the current production speed of the ith production line according to the production speed change, avoid the mismatch between the production speed of the production lines and the speed of order allocation, ensure the stability of production efficiency and avoid the backlog of orders.

The interaction between the network device and the control terminal in the above communication system will be described in detail with reference to the method.

Referring to fig. 3, an embodiment of the present application provides a method for automatically adjusting a production line speed based on an industrial large model, the method comprising:

s301, the AF obtains the production state change condition of each of the M production lines within a specified period of time from the NEF network element by subscribing to an open service from the capability open function NEF network element in the first PLMN.

The M production lines are connected to a second PLMN, the second PLMN is a visited public land mobile network VPLMN of the M production lines, and the first PLMN is a home public land mobile network HPLMN of the M production lines, that is, subscription data of each of the M production lines is stored in the HPLMN.

The AF may send a capability open subscription request to the NEF network element.

Wherein, the capability open subscription request can be used for requesting subscription to the production state change of each of M production lines in a specified time period. For example, the capability open subscription request includes at least one of: the identity of each of the M production lines (e.g., a respective user permanent identifier (SUbscription Permanent Identifier, SUPI)), information indicative of a specified time period, or information indicative of a production state change for the subscription service, at least one of which is used to jointly indicate a production state change for each of the M production lines requesting subscription within the specified time period. Alternatively, the specified period may be a periodic period, and the length of the specific period is not limited in the embodiments of the present application.

The data management network element UDM network element in the first PLMN may receive a capability open subscription request forwarded by the NEF network element. That is, unlike the capability openness of the prior art, embodiments of the present application may need to complete the capability openness through a roaming guidance (SoR) procedure, so the NEF network element needs to forward the capability openness subscription request to the UDM network element, instead of forwarding the capability openness subscription request to the PCF network element as in the prior art.

The UDM network element determines whether the type of AF request opening is the first opening type or the second opening type according to the capability opening subscription request and subscription data of M production lines (subscription data of M production lines are stored locally in the UDM network element, specifically, subscription data of M production lines may be respective subscription data of M production lines or M production lines may be taken as a group, and subscription data of the group). The first opening type refers to opening performed in a first PLMN, and the second opening type refers to opening performed in other PLMNs except the first PLMN. The subscription data for the M production lines may be used to indicate that the M production lines are currently accessing the second PLMN, e.g. the subscription data contains an identification of the second PLMN. Under the condition that the type of the AF request opening is determined to be the second opening type, the UDM network element sends SoR configuration information to the M production lines through a SoR flow, wherein the SoR configuration information is used for indicating the M production lines to report the production state change of the M production lines in a specified time period, namely, the UDM network element can send the information in the capability opening subscription request to the M production lines as SoR configuration information.

The UDM network element may receive the SoR response returned by the M production lines for the SoR configuration information, where the SoR response includes a production state change condition of each of the M production lines in a specified time period, in other words, when the M production lines acquire the SoR configuration information and learn that a production state change of each of the M production lines in the specified time period needs to be reported, the M production lines multiplex an end message of the SoR process, such as the SoR response returns the production state change condition of each of the M production lines in the specified time period to the UDM network element. Wherein, the production state change condition of each of the M production lines in the specified time period can comprise at least one of the following: the number of orders for the production business that each of the M production lines has completed within the specified time period, the change in the number of orders for the production business that each of the M production lines is producing within the specified time period, the change in the number of orders for the production business that each of the M production lines waits to produce within the specified time period, the number of orders for the production business that each of the M production lines is producing at the end of the specified time period, or the number of orders for the production business that each of the M production lines waits to produce at the end of the specified time period. Wherein, the change of the order number of the production business which is produced by each of the M production lines in the specified time period refers to: at the beginning of the specified time period, the difference between the number of orders of the production business being produced by each of the M production lines and the number of orders of the production business being produced by each of the M production lines at the end of the specified time period; wherein, the change of the order number of the production business of each M production lines waiting to be produced in a specified time period refers to: at the beginning of the specified time period, the M production lines each wait for the difference in the number of orders of the production service to be produced from the M production lines each wait for the number of orders of the production service to be produced at the end of the specified time period.

It can be understood that, since the specified time period may be a periodic time period, the production state change of each of the M production lines in the specified time period may be specifically also the production state change of each of the M production lines in the current period.

In this way, the UDM network element may send a capability open subscription response to the AF through the NEF network element according to the SoR response, and accordingly, the AF receives the capability open subscription response returned by the NEF network element according to the capability open subscription request, where the capability open subscription response is used to indicate (or include) a production state change condition of each of the M production lines in a specified period of time.

It can be understood that if the UDM network element indicates that the M production lines currently access the second PLMN according to the subscription data of the M production lines, determining that the AF passes the capability open subscription request, where the requested open type is the second open type.

It can also be understood that if the UDM network element indicates that the M production lines currently access the first PLMN according to subscription data of the M production lines, determining that the AF passes the capability open subscription request, where the requested open type is the first open type. At this time, for the first opening type, the UDM network element does not trigger the SoR flow, but completes opening through the control plane of the first PLMN, for example, the UDM network element sequentially passes through PCF network elements-SMF network elements-AMF network elements in the first PLMN, informs RAN equipment in the first PLMN of production state changes of M production lines in a specified time period, that is, RAN equipment accessed by the M production lines, so that the RAN equipment obtains the production state change conditions of the M production lines in the specified time period from the M production lines according to the production state changes, and sequentially passes through the control plane, for example, AMF network elements-SMF network elements-NEF network elements in the first PLMN, and finally is transmitted to the AF by the NEF network elements. Of course, for the first open type, since the M production lines are currently connected to the first PLMN and are in the same PLMN as the AF, the AF may directly instruct the M production lines to report the production state change condition of each of the M production lines in the specified time period to the AF without going through the open flow.

S302, AF processes the production state change condition of each of M production lines in a specified time period through an industrial large model, and determines the estimated result of the ith production line in the M production lines.

The estimated result of the ith production line is used for indicating that the production speed of the ith production line is about to change, and i is any integer from 1 to M. The production speed of the ith production line is about to be changed specifically as follows: the production speed of the ith production line is to be increased by a first pre-estimated value in a pre-estimated time period, or the production speed of the ith production line is to be decreased by a second pre-estimated value in a pre-estimated time period; the estimated time period is a future time period estimated by the industrial large model, specifically, the estimated time period when the estimated time is longer than the preset time period can be executed, the specific time period is not limited, and the estimated time period can be longer or shorter according to the capability of the industrial large model.

The first predetermined value may be a proportional value, such as +20%, indicating a 20% improvement. Similarly, the second predicted value may be a proportional value, such as-20%, indicating a 20% decrease.

S303, the AF requests the second PLMN to adjust the current production speed of the ith production line according to the estimated result of the ith production line.

Mode 1: in the case where the production rate of the ith production line is to be increased by the first predicted value in the predicted period of time. AF requests the second PLMN to adjust the current production speed of the ith production line according to the estimated result of the ith production line, and the AF comprises the following steps: and the AF sends indication information to RAN equipment in the second PLMN, wherein the indication information is used for indicating that the production speed of the ith production line is to be increased by a first pre-estimated value within a pre-estimated time period, the RAN equipment is the RAN equipment currently accessed by the ith production line, and the production speed of the ith production line is to be increased by the first pre-estimated value within the pre-estimated time period and is used for implicitly indicating that the RAN equipment needs to indicate that the ith production line is to be increased by the current production speed according to the first pre-estimated value.

Specifically, the RAN device increases the side resources used by the PC5 connection configured to the ith production line from the first number of resources to the second number of resources according to the first predetermined value. For example, the first predicted value corresponds to the second number of resources in proportion, for example, the first predicted value is +20%, and the second number of resources may be about 20% greater than the first number of resources. The RAN equipment sends side resource allocation information to the ith production line. The side line resource configuration information is used for indicating that the side line resources used by the PC5 connection configured to the ith production line are increased from the first resource number to the second resource number (specifically, the side line resources of the second resource number may be indicated, for example, specific time-frequency positions), and the side line resources used by the PC5 connection configured to the ith production line are increased from the first resource number to the second resource number to implicitly indicate that the ith production line needs to correspondingly increase the current production speed according to the second resource number.

Mode 2: in the case that the production rate of the ith production line is about to decrease by the second estimated value in the estimated time period, the AF requests the second PLMN to adjust the current production rate of the ith production line according to the estimated result of the ith production line, including: and the AF sends indication information to RAN equipment in a second PLMN, wherein the RAN equipment is the RAN equipment currently accessed by the ith production line, the indication information is used for indicating that the production speed of the ith production line is about to be reduced by a second pre-estimated value in a pre-estimated time period, and the production speed of the ith production line is about to be reduced by the second pre-estimated value in the pre-estimated time period and is used for implicitly indicating that the RAN equipment needs to indicate the ith production line to reduce the current production speed according to the second pre-estimated value.

Specifically, the RAN device reduces the sidestream resources used by the PC5 connection configured for the ith production line from the first resource number to the second resource number according to the second predetermined value. The second predicted value corresponds to the second number of resources in proportion, for example, the second predicted value is-20%, and the second number of resources may be about 20% less than the first number of resources. The RAN device sends side resource allocation information to the ith production line, where the side resource allocation information is used to instruct that the number of side resources used by the PC5 connection configured to the ith production line is reduced from the first resource number to the second resource number (specifically, the number of side resources of the second resource number may be indicated, e.g. a specific time-frequency location), and the number of side resources used by the PC5 connection configured to the ith production line is reduced from the first resource number to the second resource number to implicitly indicate that the ith production line needs to correspondingly reduce the current production speed according to the second resource number.

In summary, in the case where the AF management line and the AF are distributed in different PLMNs, for example, the AF is located in a first PLMN, the M production lines are connected to a second PLMN, and the second PLMN is a VPLMN of the M production lines, and the first PLMN is an HPLMN of the M production lines, so that the AF of the HPLMN may obtain, through subscription to an open service, a production state change condition of each of the M production lines in a specified time period from the VPLMN. On the basis, AF analyzes the production state change condition of each M production lines in a specified time period through a large module so as to estimate the future production speed change of the ith production line in the M production lines, instruct VPLMN to adjust the current production speed of the ith production line according to the production speed change, avoid the mismatch between the production speed of the production line and the speed of order allocation, ensure the stability of production efficiency and avoid the occurrence of order backlog.
