Description

Order distribution management method and device based on big data analysis

Technical Field

The application relates to the technical field of communication, in particular to an order distribution management method based on big data analysis.

Background

The third generation partnership project (3rd generation partnership project,3GPP) defines a handover procedure for a terminal. Specifically, the base station may instruct the terminal to perform cell measurement continuously, report signal quality of a serving cell and a neighboring cell of the terminal, and gradually decrease signal quality of the serving cell and gradually increase signal quality of the neighboring cell along with movement of the terminal, so that the base station finally switches the terminal to the neighboring cell. For example, taking a business scenario as an order delivery as an example, a dispatcher holds a terminal for order delivery management, determines a route of order delivery by himself, and then moves along the route, during which the terminal reports signal quality in real time, and triggers a base station to actively or passively perform cell switching for multiple times, so as to provide network services during delivery.

It can be seen that the current handover is dynamically determined by the base station according to the signal quality, and this method may not be suitable for future application scenarios.

Alternatively, the network service may subscribe to a certain service, and the NWDAF network element notifies when the network slice changes or a certain threshold is reached.

The technical solutions in the present application will be described below with reference to the accompanying drawings.

Referring to fig. 2, an embodiment of the present application provides a communication system, which includes an AMF network element and an NWDAF network element.

In this communication system, the delivery path of the traffic to be delivered may be fixed for the scenario of the traffic delivery, meaning that it may also be fixed by which cells it is served. Therefore, the AMF network element may analyze order information of the M services to be delivered by requesting the NWDAF network element to obtain N cell handover paths covering the delivery paths of the M services to be delivered. In this way, the AMF network element configures the ith cell switching path in the N cell switching paths to a plurality of cells on the ith cell switching path, so that the cells do not need to perform signal measurement and reporting, and the cells are directly switched to the terminal executing the service to be configured according to the cell switching paths, so that communication redundancy caused by performing signal measurement and reporting can be avoided.

Reference may be made in particular to the following method examples.

Referring to fig. 3, an embodiment of the present application provides an order distribution management method based on big data analysis. The method can be suitable for communication between the AMF network element and the NWDAF network element. The method comprises the following steps:

s301, the AMF network element receives a service request from the AF.

The service request comprises order information of M services to be distributed, wherein M is an integer greater than 1. The order information may include a start position and an end position of each of the M services to be distributed, and may further include types of terminals, such as type1, type2, type3, etc., that execute the M services to be distributed.

S302, the AMF network element requests the NWDAF network element to analyze order information according to the service request.

S303, the AMF network element obtains an analysis result of the NWDAF network element on order information.

The analysis result is used for indicating N cell switching paths, N is a positive integer less than or equal to M, and the N cell switching paths cover the delivery paths of M services to be delivered.

For example, the AMF network element may send a data subscription analysis request to the NWDAF network element according to the service request. The data subscription analysis request may include order information, and the data subscription analysis request further includes a data analysis type of the AMF request, where the data analysis type is cell handover path analysis, so as to jointly indicate that the NWDAF network element needs to perform analysis of coverage paths for M services to be distributed. The NWDAF network element may receive the data subscription analysis response from the AMF network element. The NWDAF network element may determine delivery paths of the M services to be delivered according to the data subscription analysis response. The NWDAF network element determines N cell switching paths according to the delivery paths of the M services to be delivered. The NWDAF network element sends a data subscription analysis response to the AMF network element. Accordingly, the AMF network element may receive a data subscription analysis response from the NWDAF network element, wherein the data subscription analysis response includes the analysis result.

The NWDAF network element may determine whether there is a service to be delivered matching the history delivery service that has been historically analyzed by the NWDAF network element, from the M services to be delivered. Optionally, matching the to-be-delivered service with the historical delivery service in the M to-be-delivered services includes: the starting location of the order in the order information matches the starting location of the order for the historical delivery service (e.g., the distance between the locations is less than the distance threshold), and the ending location of the order in the order information matches the ending location of the order for the historical delivery service (e.g., the distance between the locations is less than the distance threshold). If the to-be-delivered service in the M to-be-delivered services is matched with the historical delivery service, the NWDAF network element determines the delivery path of the historical delivery service as the delivery path of the to-be-delivered service matched with the historical delivery service. Wherein, for at least part of the M services to be delivered that do not match the historical delivery service, the NWDAF network element instructs the AMF network element to provide a delivery path for at least part of the services to be delivered. Correspondingly, after the AMF network element sends a data subscription analysis request to the NWDAF network element according to the service request, before the AMF network element receives a data subscription analysis response from the NWDAF network element, the AMF network element may receive a data subscription analysis requirement from the NWDAF network element, where the data subscription analysis requirement is used to indicate that the AMF network element needs to provide a delivery path of at least some of M services to be delivered; the AMF network element acquires a delivery path of at least part of the service to be delivered from the AF according to the data subscription analysis requirement; the AMF network element sends a response of the data subscription analysis requirement to the NWDAF network element, wherein the response comprises at least part of the delivery path of the service to be delivered.

That is, the AF provides a delivery path of at least part of the traffic to be delivered only at least part of the traffic to be delivered that does not match the history of the traffic to be delivered, so that the communication overhead can be reduced.

It can be understood that the specific implementation of generating N cell handover paths by the NWDAF network element may be as follows: for each delivery path of the service to be delivered, the NWDAF network element may determine the cell that is therefore capable of covering the delivery path of the service to be delivered. At this time, if the same section of the delivery path of the service to be delivered is covered by at least three cells, the two cells with the first two long sections are reserved according to the lengths of the sections of the delivery path of the service to be delivered, which are respectively covered by the at least three cells. And then, the NWDAF network element simulates the occurrence of the cell switching according to the sequence from front to back of the distribution path of the service to be distributed, and if 2 cells can be selected for a certain switching, one cell is deleted, but the other cell which is kept needs to be ensured to be capable of being continuously overlapped with the next cell, so that the cell which is switched each time is ensured to be unique, and finally, the cell switching path which covers the distribution path of the service to be distributed is obtained.

S304, the AMF network element configures an ith cell switching path in the N cell switching paths to a plurality of cells on the ith cell switching path, and i traverses 1 to N.

The AMF network element is configured to an ith cell switching path of the first cell and is used for indicating neighbor cells of the first cell on the ith cell switching path.

Optionally, the delivery path covered by the ith cell switching path is a delivery path of at least one service to be delivered in the M services to be delivered. The AMF network element may further send type information to the plurality of cells according to the type of the terminal in the order information. The type information is used for indicating the type of a terminal executing at least one service to be distributed, and when the terminal with the type accesses any one of a plurality of cells, the cell switches the terminal according to an ith cell switching path. Correspondingly, for the first cell, under the condition that the first terminal of the type is accessed to the first cell, the first terminal indicates the first terminal to only measure and report the signal quality of the service cell, and does not measure and report the signal quality of the neighbor cell of the service cell; and under the condition that the signal quality of the first cell reported by the first terminal is smaller than a signal quality threshold value, the first cell switches the first terminal to a neighboring cell of the first cell on the ith cell switching path according to the ith cell switching path. Alternatively, the first cell may switch the first terminal to a neighboring cell of the first cell on the i-th cell switching path only according to the location of the first terminal. In this way, the communication overhead of the first cell and the first terminal for performing signal measurement and reporting can be omitted.

In summary, for the scenario of the delivery service, the delivery path of the service to be delivered may be fixed, meaning that it may also be fixed by which cells it is served. Therefore, the AMF network element may analyze order information of the M services to be delivered by requesting the NWDAF network element to obtain N cell handover paths covering the delivery paths of the M services to be delivered. In this way, the AMF network element configures the ith cell switching path in the N cell switching paths to a plurality of cells on the ith cell switching path, so that the cells do not need to perform signal measurement and reporting, and the cells are directly switched to the terminal executing the service to be configured according to the cell switching paths, so that communication redundancy caused by performing signal measurement and reporting can be avoided.

It will be appreciated that the above manner is only an example, and other implementations are also possible, for example, the AMF may request that the AUSF network element configure a specific security key for M services to be distributed, so as to ensure communication security. For example, before a terminal executing the M services to be delivered accesses a cell in the N cell handover paths, the AMF requests the AUSF network element to generate a key for the M services to be delivered, that is, a key of service granularity, and configures the key to the cell in the N cell handover paths. The terminals executing the M services to be distributed can make the same deduction to ensure the key alignment. That is, the keys of the M services to be delivered are not conventional AS keys or NAS keys, but are keys at the service granularity specific to the M services to be delivered, and the keys of different services to be delivered may be different.

The method provided in the embodiment of the present application is described in detail above in connection with fig. 3. An order distribution management apparatus based on big data analysis for performing the method provided by the embodiment of the present application is described below.

Wherein the apparatus is applied to an AMF network element, the apparatus being configured to: the AMF network element receives a service request from an AF, wherein the service request comprises order information of M services to be distributed, and M is an integer greater than 1; the AMF network element requests the NWDAF network element to analyze order information according to the service request; the AMF network element obtains analysis results of the NWDAF network element on order information, wherein the analysis results are used for indicating N cell switching paths, N is a positive integer less than or equal to M, and the N cell switching paths cover delivery paths of M services to be delivered; the AMF network element configures an ith cell switching path in the N cell switching paths to a plurality of cells on the ith cell switching path, and i traverses 1 to N.
