[0055] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the embodiments of the present invention are further described in detail below through specific implementation methods combined with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0056] Embodiment 1:

[0057] In order to obtain the shared terminal information of the mobile terminal as the hotspot in the 5G network, the first acquisition identifier sent by the PCF network element to the SMF network element is defined in this embodiment to indicate the acquisition of the shared terminal information of the terminal as the hotspot, that is, the indication field and its specific field value for indicating the acquisition of the shared terminal information between the PCF network element and the SMF network element are defined; and the field for exchanging the shared terminal information between the PCF network element and the SMF network element is defined. At the same time, the second acquisition identifier sent by the SMF network element to the UPF network element is defined in this embodiment to indicate the acquisition of the shared terminal information of the terminal as the hotspot, that is, the indication field and its specific field value for indicating the acquisition of the shared terminal information between the SMF network element and the UPF network element are defined; and the field for exchanging the shared terminal information between the SMF network element and the UPF network element is defined.

[0058] It should be understood that in this embodiment, the second acquisition identifier is an identifier corresponding to the first acquisition identifier, and the two can be defined as the same value or different values, which can be flexibly set according to specific application scenarios, as long as they do not conflict with existing values.

[0059] In this embodiment, based on the above definition, the PCF network element can send a first acquisition identifier to the SMF network element according to demand or policy to trigger the SMF network element to send a second acquisition identifier to the UPF network element, thereby triggering the UPF network element to obtain shared terminal information, and feed back the acquired shared terminal information to the SMF network element, which is then sent to the PCF network element through the SMF network element. Therefore, in the 5G network, it is possible to obtain the shared terminal information of the terminal serving as a hotspot, thereby providing operators with data for user behavior analysis, better protecting the interests of each operator, and enhancing the core competitiveness of operators in 5G network deployment.

[0060] For ease of understanding, this embodiment below uses PCF network element, SMF network element and UPF network element as examples to illustrate the steps of obtaining shared terminal information executed in the shared terminal service control method in the 5G network.

[0061] For the PCF network element side, see Figure 1 As shown, the shared terminal service control method in the 5G network performs but is not limited to the following steps:

[0062] S101: The PCF network element sends a first control message to the SMF network element. The first control message includes a first acquisition identifier for instructing to acquire the shared terminal information under the terminal serving as the hotspot.

[0063] It should be understood that the terminal used as the hotspot in this embodiment may include a mobile terminal, such as a mobile phone, IPAD or other mobile terminal, and may also include a non-mobile terminal, such as a PC terminal or the like.

[0064] The first control message in this embodiment may include, but is not limited to, at least one of the following messages:

[0065] The response message fed back by the SMF network element after receiving the request message sent by the PCF network element, as well as the request message actively sent by the SMF network element to the PCF network element. For example:

[0066] In one example, the first control message may include a network creation response message; at this time, when the PCF network element receives the network creation request message sent by the SMF network element, it sends a network creation response message including the first acquisition identifier to the SMF, wherein the network creation request message is triggered by the SMF network element in the process of the terminal as a hotspot accessing the network according to the network creation session message sent by the terminal;

[0067] In another example, the PCF network element may send a request message to the SMF after the terminal serving as a hotspot accesses the network, and the request message includes a first acquisition identifier.

[0068] In some examples of this implementation example, the first acquisition identifier can be used for but not limited to indicating the acquisition of the number of shared terminals, that is, the acquisition of the number of shared terminals under the terminal as a hotspot (the shared terminals here are the terminals that access the hotspot provided by the terminal as a hotspot). Among them, when acquiring the number of shared terminals, it can be indicated that only the number of shared terminals is statistically acquired according to specific application requirements, and it can also be indicated that while the number of shared terminals is statistically acquired, whether there are shared terminals disguised as hotspots among the shared terminals under the terminal as a hotspot can be identified according to specific application requirements, and when identified, it is reported to the PCF network element. Of course, other information of the shared terminals can also be statistically analyzed according to needs, which will not be repeated here.

[0069] In some examples of this embodiment, the first control message sent by the PCF network element to the SMF network element may also include identification information of each terminal that serves as a hotspot and needs to query shared terminal information. Among them, the PCF can obtain the shared terminal information of all terminals that are currently connected to the network and serve as hotspots. At this time, the first control message may include obtaining the identification information of all terminals that are currently connected to the network and serve as hotspots; the PCF network element can also obtain specific terminals among all terminals that are currently connected to the network and serve as hotspots according to needs to query shared terminal information. The specific method can be flexibly set according to the specific application scenario.

[0070] S102: The PCF network element receives a first acquisition response message sent by the SMF network element, where the first acquisition response message includes the acquired shared terminal information.

[0071] The first acquisition response message exchanged between the PCF network element and the SMF network element predefines which fields are used to carry the shared terminal information; and the specific fields used can be flexibly set as long as they do not conflict with the existing defined fields.

[0072] In some examples of this embodiment, the PCF network element can further control the shared terminal service based on the shared terminal information included in the first acquisition response message. For example, the control may include but is not limited to speed limiting, service blocking, and security control of shared terminals that disguise as hotspots.

[0073] For SMF network element side, see Figure 2 As shown, the shared terminal service control method in the 5G network performs but is not limited to the following steps:

[0074] S201: The SMF network element receives a first control message sent by a policy control function entity PCF network element.

[0075] As shown in the above analysis, the first control message includes a first acquisition identifier for instructing to acquire the shared terminal information connected to the terminal serving as the hotspot.

[0076] S202: The SMF network element sends a second control message to the core network user plane function entity UPF network element based on the first control message, and the second control message includes a second acquisition identifier corresponding to the first acquisition identifier.

[0077] Among them, the PCF network element and the SMF network element communicate via the N7 interface, and the SMF network element and the UPF network element communicate via the N4 interface. Therefore, after the SMF network element receives the first control message from the PCF network element via the N7 interface, it generates a second control message based on the first control message and sends it to the UPF network element via the N4 interface. The second control message sent includes a second acquisition identifier corresponding to the first acquisition identifier, and as mentioned above, the second acquisition identifier can be the same identifier as the first acquisition identifier, or it can be an identifier different from the first acquisition identifier, as long as the UPF network element knows that the PCF network element currently needs to obtain the shared terminal information under the terminal designated as the hotspot.

[0078] S203: The SMF network element receives a second acquisition response message sent by the UPF network element according to the second control message, where the second acquisition response message includes the acquired shared terminal information.

[0079] S204: The SMF network element sends a first acquisition response message to the PCF network element according to the second acquisition response message, wherein the first acquisition response message includes the acquired shared terminal information. In this way, the PCF network element can extract the shared terminal information from the first acquisition response message.

[0080] For UPF network element side, see Figure 3 As shown, the shared terminal service control method in the 5G network performs but is not limited to the following steps:

[0081] S301: The UPF network element receives the second control message sent by the SMF network element.

[0082] As shown in the above analysis, the second control message in this step is sent by the SMF network element according to the first control message received from the PCF network element. The first control message includes a first acquisition identifier for indicating that the shared terminal information under the terminal as the hotspot is acquired, and the second control message includes a second acquisition identifier corresponding to the first acquisition identifier;

[0083] S302: The UPF network element acquires the shared terminal information according to the second control message.

[0084] For example, in one example, the UPF network element can analyze the number of shared terminals (or other information of the shared terminals) using the hotspots provided by each terminal as a hotspot by parsing the data service messages of each terminal accessing the 5G network. The UPF network element carries the acquired number of shared terminals in the second acquisition response message and sends it to the SMF network element through the N4 interface.

[0085] S303: Send a second acquisition response message to the SMF network element, the second acquisition response message includes the acquired shared terminal information; the second acquisition response message predefines which fields are used to carry the shared terminal information, and the specific fields can be flexibly set as long as they do not conflict with the existing defined fields.

[0086] It can be seen that in this embodiment, the shared terminal information (such as the number of users) of the shared hotspot can be reported to the PCF network element through the UPF network element and the SMF network element. The PCF network element can clearly analyze the user's network sharing usage, and can also control the terminals in the network that attempt to disguise themselves as hotspot users through hotspot sharing. At the same time, it also provides operators with user behavior analysis data, better protects the interests of each operator, and enhances the core competitiveness of operators in 5G network deployment.

[0087] Embodiment 2:

[0088] Based on the above embodiment, this embodiment provides a shared terminal service control device for a 5G network, which is arranged in a PCF network element. Figure 4 As shown, it includes:

[0089] The first sending module 401 is used to send a first control message to the session management function entity SMF network element. The first control message includes a first acquisition identifier for indicating the acquisition of shared terminal information under the terminal serving as the hotspot. For the specific sending process, please refer to the above embodiment and will not be repeated here.

[0090] The first receiving module 402 is used to receive a first acquisition response message sent by the SMF network element, and the first acquisition response message includes the acquired shared terminal information. The specific receiving process is shown in the above embodiment, and will not be repeated here.

[0091] This embodiment provides a shared terminal service control device for a 5G network, which is set in an SMF network element. Figure 5 As shown, including:

[0092] The second receiving module 501 is used to receive a first control message sent by a policy control function entity PCF network element, the first control message including a first acquisition identifier for indicating acquisition of shared terminal information hung under the terminal serving as a hotspot; and to receive a second acquisition response message sent by a UPF network element according to a second control message, the second acquisition response message including the acquired shared terminal information; the specific receiving process is shown in the above embodiment and will not be repeated here.

[0093] The second sending module 502 is used to send a second control message to the core network user plane function entity UPF network element according to the first control message, the second control message includes a second acquisition identifier corresponding to the first acquisition identifier; and to send a first acquisition response message to the PCF network element according to the second acquisition response message, the first acquisition response message includes the acquired shared terminal information. The specific sending process is shown in the above embodiment and will not be repeated here.

[0094] This embodiment provides a shared terminal service control device set in a UPF network element for use in a 5G network. Figure 6 As shown, including:

[0095] The third receiving module 601 is used to receive a second control message sent by the SMF network element. The second control message is sent by the SMF network element according to the first control message received from the PCF network element. The first control message includes a first acquisition identifier for indicating the acquisition of shared terminal information hung under the terminal serving as the hotspot, and the second control message includes a second acquisition identifier corresponding to the first acquisition identifier. For the specific receiving process, please refer to the above embodiment and will not be repeated here.

[0096] The information acquisition module 602 acquires the shared terminal information according to the second control message. The specific acquisition process is shown in the above embodiment and will not be described again.

[0097] The third sending module 603 is used to send a second acquisition response message to the SMF network element, and the second acquisition response message includes the acquired shared terminal information. The specific sending process is shown in the above embodiment and will not be repeated here.

[0098] For ease of understanding, this embodiment is based on the above and combined with Figure 7 The 5G network architecture shown is provided as an example for illustration. Figure 7 In the network, the N7 interface is supported between the SMF network element and the PCF network element; the N4 interface is directly supported between the SMF network element and the UPF network element.

[0099] In one example, assuming that the speed limit control needs to be performed on the shared terminal, the terminal UE (in this example, it is assumed that it is the mobile terminal A) is the terminal of the hotspot, and an example process of obtaining the shared terminal under the mobile terminal A is shown in Figure 8 As shown, including:

[0100] S801: Mobile terminal user A accesses the 5G network system and sends a network creation session message to the SMF network element.

[0101] S802: The core network SMF network element interacts with the PCF network element and receives a network creation response message including the first acquisition identifier sent by the PCF network element. For this process, please refer to Fig. 9 As shown, including:

[0102] S901: The SMF network element sends a network creation request message to the PCF network element.

[0103] In this step, when the SMF network element receives a message from the terminal user to access the network and create a session, it will report the user information to the PCF network element. After receiving the request message from the SMF network element, the PCF network element will instruct the SMF network element to report the number of shared terminals on the terminal that serves as the hotspot based on the user's contract information and a pre-established strategy.

[0104] S902: The PCF network element sends a network creation response message including a first acquisition identifier to the SMF network element.

[0105] S803: The SMF network element sends a second control message including a second acquisition identifier to the SMF network element based on the network creation response message.

[0106] The SMF network element receives the network creation response message including the first acquisition identifier sent by the PCF network element, and knows that it needs to report the number of shared users of the terminal to the PCF. At this time, the SMF network element will trigger the interaction with the UPF network element.

[0107] Assume that mobile terminal A has successfully accessed the 5G network and turned on the hotspot sharing function.

[0108] Other terminal users access data services through the hotspot opened by mobile terminal A instead of using the terminal's own 5G network.

[0109] S804: The UPF network element receives data messages from other terminal users when they access data services through hotspot sharing, parses feature content in the messages, and obtains the number of shared terminals provided by mobile terminal A.

[0110] S805: The UPF network element carries the acquired number of shared terminals in the second acquisition response message and sends it to the SMF network element through the N4 interface.

[0111] S806: After receiving the second acquisition response message transmitted by the UPF network element, the SMF network element generates a first acquisition response message including the number of shared terminals and reports it to the PCF network element through the N7 interface.

[0112] The interface message interaction process between the SMF network element and the PCF network element is as follows: Fig.10 As shown, incl.

[0113] S1001: The SMF network element sends a first acquisition response message to the PCF network element.

[0114] S1002: The PCF network element sends a 200OK confirmation message to the SMF network element.

[0115] Through the above process, PCF obtains the number of shared terminals. At this time, PCF can issue policies according to the operator's plan or requirements to limit the speed of user terminals that access the network through hotspot sharing.

[0116] In another example, assume that after a 5G terminal user serving as a hotspot accesses the network, the PCF network element proactively sends a request message to obtain hotspot shared terminal information, and blocks services for terminals accessing data through the hotspot based on the obtained shared terminal information. For an example process, see Fig.11 As shown, including:

[0117] S1101: Mobile terminal user A accesses the 5G network system and turns on the hotspot sharing function.

[0118] S1102: The PCF network element actively sends a request message including a first acquisition identifier to the SMF network element, instructing to report the number of shared terminals connected to and from the terminal serving as the hotspot.

[0119] In this step, the interface message interaction process between the SMF network element and the PCF network element is as follows: Fig.12 .

[0120] S1201: The PCF network element sends a request message including a first acquisition identifier to the SMF network element.

[0121] S1202: The SMF network element feeds back a 200OK message to the PCF network element.

[0122] S1103: The SMF network element sends a second control message including a second acquisition identifier to the SMF network element based on the request message including the first acquisition identifier.

[0123] The SMF network element receives the request message including the first acquisition identifier sent by the PCF network element, and knows that it needs to report the number of shared users of the terminal to the PCF. At this time, the SMF network element will trigger the interaction with the UPF network element.

[0124] Assume that mobile terminal A has successfully accessed the 5G network and turned on the hotspot sharing function.

[0125] Other terminal users access data services through the hotspot opened by mobile terminal A instead of using the terminal's own 5G network.

[0126] S1104: The UPF network element receives data messages from other terminal users when they access data services through hotspot sharing, parses feature content in the messages, and obtains the number of shared terminals provided by mobile terminal A.

[0127] S1105: The UPF network element carries the acquired number of shared terminals in the second acquisition response message and sends it to the SMF network element through the N4 interface.

[0128] S1106: After receiving the second acquisition response message transmitted by the UPF network element, the SMF network element generates a first acquisition response message including the number of shared terminals and reports it to the PCF network element through the N7 interface.

[0129] Through the above process, the PCF network element obtains the number of shared terminals. At this time, the PCF can issue policies according to the operator's plan or requirements to block services of terminals that attempt to access hotspots.
