For the SMF network element side, please refer to fig. 2, which executes but is not limited to the following steps in the shared terminal service control method in the 5G network:

S202: and the SMF network element sends a second control message to a UPF network element of the user plane functional entity of the core network according to the first control message, wherein the second control message comprises a second acquisition identifier corresponding to the first acquisition identifier.
The PCF network element and the SMF network element adopt an N7 interface for communication, and the SMF network element and the UPF network element adopt an N4 interface for communication, so that after the SMF network element receives the first control message from the PCF network element through the N7 interface, the SMF network element generates a second control message according to the first control message and sends the second control message to the UPF network element through the N4 interface. The sent second control message includes a second acquisition identifier corresponding to the first acquisition identifier, and as described above, the second acquisition identifier may be the same identifier as the first acquisition identifier or a different identifier from the first acquisition identifier, as long as the UPF network element can know that the PCF network element needs to acquire the shared terminal information of the terminal specified by the PCF network element and serving as the hot spot at present.

For the convenience of understanding, the present embodiment is described below with reference to the 5G network architecture shown in fig. 7 as an example on the basis of the foregoing. In fig. 7, an N7 interface is supported between the SMF network element and the PCF network element; the SMF network element and the UPF network element directly support an N4 interface.
In an example, assuming that speed limit control needs to be performed on a shared terminal, a terminal UE (in this example, it is assumed to be a mobile phone terminal a) is used as a terminal of a hot spot, and an example flow of acquiring a shared terminal below the mobile phone terminal a is shown in fig. 8, which includes:
s801: and the mobile phone terminal user A accesses the 5G network system and sends a network establishment session message to the SMF network element.
S802: the core network SMF network element interacts with the PCF network element, and receives a network establishment response message which is sent by the PCF network element and comprises the first acquisition identifier. The process is shown in fig. 9, and includes:
s901: the SMF network element sends a network creation request message to the PCF network element.
In this step, the SMF network element receives the session creation message of the terminal user access network, and reports the user information to the PCF network element, and the PCF network element, after receiving the request message of the SMF network element, instructs the SMF network element to report the number of shared terminals on the terminal serving as a hotspot according to a predetermined policy based on the subscription information of the user.
S902: and the PCF network element sends a network creation response message including the first acquisition identifier to the SMF network element.
S803: and the SMF network element sends a second control message comprising a second acquisition identifier to the SMF network element according to the network establishment response message.
The SMF network element receives a network establishment response message which is sent by the PCF network element and comprises a first acquisition identifier, knows that the number of the terminal sharing users needs to be reported to the PCF, and then the SMF network element triggers the interaction with the UPF network element.
Suppose that the mobile phone terminal a successfully accesses the 5G network and starts the hotspot sharing function at this time.
And other terminal users access the data service through the hot spot opened by the mobile phone terminal A without using the 5G network of the terminal.
S804: the UPF network element receives the data message when other terminal users access the data service through hotspot sharing, analyzes the characteristic content in the message, and obtains the number of the sharing terminals provided by the mobile phone terminal A.
S805: the UPF network element carries the acquired number of the shared terminals in a second acquisition response message and brings the second acquisition response message to the SMF network element through an N4 interface
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 the shared terminals, and then reports the first acquisition response message to the PCF network element through the N7 interface.
Here, the interface message interaction flow between the SMF network element and the PCF network element is shown in fig. 10, which includes.
S1001: the SMF network element sends a first acquisition response message to the PCF network element.
S1002: the PCF network element sends a 200OK acknowledgement message to the SMF network element.
Through the above process, the PCF obtains the number of shared terminals, and at this time, the PCF may issue a policy to perform speed limit control on the user terminal accessing the network through hotspot sharing according to the plan or requirement of the operator.
In another example, it is assumed that after a 5G terminal user as a hotspot accesses a network, a PCF network element actively issues a request message to obtain hot shared terminal information, and performs service blocking on a terminal performing data access through the hotspot according to the obtained shared terminal information. An example process is shown in fig. 11, which includes:
s1101: and a mobile phone terminal user A accesses the 5G network system and starts a hotspot sharing function.
S1102: and the PCF network element actively sends a request message including the first acquisition identifier to the SMF network element and indicates the number of the shared terminals which are hung up and down and report the terminals serving as the hot spots.
In this step, the interface message interaction flow between the SMF network element and the PCF network element is as shown in fig. 12.
S1201: and the PCF network element sends a request message comprising the first acquisition identifier to the SMF network element.
S1202: the SMF network element feeds back a 200OK message to the PCF network element.
