In some embodiments, the above-described communication method may be applied to a campus communication system as shown in fig. 1. The following describes a communication method provided by an embodiment of the present invention with reference to the drawings.

As shown in fig. 3, the communication method provided by the embodiment of the present invention is applied to the campus communication system 10, and includes S201 to S203.

S201, the LMF equipment determines the positioning result of the terminal.

And the positioning result is used for representing the position information of the terminal.

As a possible implementation manner, the LMF device calculates and generates a positioning result of the terminal based on the received terminal measurement data sent by the public network AMF device.

S202, the LMF equipment determines whether the terminal is a park positioning terminal.

As a possible implementation manner, the LMF device determines, from the received terminal measurement data sent by the public network AMF device, an identifier of a terminal that needs to be located. Further, the LMF equipment determines whether the terminal is a park positioning terminal or not according to the identifier of the terminal.

It should be noted that the LMF device stores in advance a mapping relationship between the identifier of the terminal and the location type, where the location type includes a campus location terminal and a non-campus location terminal. Or, a park positioning terminal set and a non-park positioning terminal set are prestored in the LMF device, the park positioning terminal identifier included in the park positioning terminal set and the non-park positioning terminal identifier included in the non-park positioning terminal set. Or, only a park positioning terminal set is pre-stored in the LMF device, and the park positioning terminal set includes the identifier of the park positioning terminal.

For example, as shown in table 1 above, if the mapping relationship between the identifier of the terminal and the location type is pre-stored in the LMF device, the LMF device queries, according to the obtained identifier of the terminal, the location type having a mapping relationship with the identifier of the terminal from the mapping relationship between the identifier of the terminal and the location type, and further determines that the terminal is a campus location terminal or a non-campus location terminal.

As shown in table 2, if the LMF device is pre-stored in the campus positioning terminal set and the non-campus positioning terminal set, the LMF device queries whether the identifier of the terminal exists in the identifiers of the terminals included in the campus positioning terminal set, and if the LMF device queries the identifier of the terminal in the campus positioning terminal set, the LMF device determines that the terminal is the campus positioning terminal.

As shown in table 3 below, if only the campus positioning terminal set is stored in the LMF device in advance, the LMF device queries whether the identifier of the terminal is included in the identifiers of the terminals included in the campus positioning terminal set. And if the LMF equipment inquires the identifier of the terminal in the identifiers of the terminals included in the park positioning terminal, determining that the terminal is the park positioning terminal.

And S203, the LMF equipment sends the positioning result of the terminal to the GMLC equipment under the condition that the terminal is the park positioning terminal, so that the GMLC equipment sends the positioning result of the terminal to the server.

As a possible implementation manner, based on determining whether the terminal is the campus positioning terminal in step S202, if the terminal is the campus positioning terminal, the LMF device carries the positioning result in the terminal Location result Response message Nlmf _ Location _ determination Location Response, selects to send the positioning result of the terminal to the GMLC device, and sends the positioning result of the terminal to the server initiating the positioning request through the GMLC device.

Illustratively, the fields included in the terminal location result response message are as shown in table 4 below.

Table 4: terminal position result response message

It can be understood that after the LMF device determines that the terminal is the campus positioning terminal, it determines that the positioning information of the terminal is required to be protected, and then when the LMF device feeds back the positioning result to the server initiating the positioning request, the LMF device directly sends the positioning result to the GMLC device deployed under the campus network, so that the risk that the positioning result is leaked due to the fact that the positioning result is forwarded by the public network AMF device is eliminated, and the positioning information of the campus positioning terminal is protected.

In one design, in order to enable the LMF device to select to send a terminal location result to the GMLC device when determining that the terminal is a campus location terminal, as shown in fig. 4, the communication method according to the embodiment of the present invention further includes S301 to S302.

S301, the LMF equipment receives a terminal positioning request message sent by the public network AMF equipment.

The terminal positioning request message is generated by the public network AMF equipment responding to a positioning request of the server, and comprises the address of the GMLC equipment.

As a possible implementation manner, the LMF device receives a terminal Location request message sent by the public network AMF device, where the terminal Location request message is a terminal Location request message in which an address of the GMLC device is newly added to the public network AMF device on the basis of a conventional terminal Location request message Nlmf _ Location _ terminal Location, so that the LMF device can determine the address of the GMLC device forwarding the server Location request after receiving the terminal Location request message.

For example, the modified terminal Location request message Nlmf _ Location _ determination Location is shown in table 5 below.

Table 5: modified terminal location request message

Terminal identification	LCS Correlation Identifier
		Type of user	Client Type
Serving cell identity	Serving cell identifier
		Terminal support for LPP indication	an indication if UE supports LPP
Required QoS	the required QoS
		AMF device identification	AMF identity
…	…
		GMLC device address	GMLC IP address

S302, the LMF device acquires the address of the GMLC device from the terminal positioning request message.

As a possible implementation manner, after receiving the terminal location request message, the LMF device generates a terminal measurement request based on information such as a terminal identifier, a user type, a serving cell identifier, an LPP (long term evolution protocol) supported by the terminal, a required quality of service (QoS), and an AMF device identifier, and sends the terminal measurement request to the AMF device in the public network, and stores the determined GMLC device address in the local.

It can be understood that, by changing the terminal location request message sent by the public network AMF device in the location request flow, the LMF device can obtain the address of the GMLC device after receiving the terminal location request message, so that the LMF device can select the address of the GMLC device to send the location result of the terminal after determining the location result of the terminal.

In one design, in order to enable the LMF device to support the positioning processes of all terminals, as shown in fig. 5, in a case that a terminal performing positioning is a non-campus positioning terminal, the communication method provided in the embodiment of the present invention further includes S401 to S402.

Further, the LMF equipment determines whether the terminal is a non-park positioning terminal or not according to the identifier of the terminal.

As shown in table 2, if the LMF device is pre-stored in the campus positioning terminal set and the non-campus positioning terminal set, the LMF device queries whether the identifier of the terminal exists in the identifiers of the terminals included in the non-campus positioning terminal set, and if the LMF device queries the identifier of the terminal in the non-campus positioning terminal set, the LMF device determines that the terminal is the non-campus positioning terminal.

As shown in table 3, if only the campus positioning terminal set is stored in the LMF device in advance, the LMF device queries whether the identifier of the terminal is included in the identifiers of the terminals included in the campus positioning terminal set. And if the LMF device does not inquire the identifier of the terminal in the identifiers of the terminals included in the park positioning terminal, determining that the terminal is the non-park positioning terminal.

S402, the LMF device sends the positioning result of the terminal to the public network AMF device under the condition that the terminal is the non-park positioning terminal, so that the public network AMF device sends the positioning result of the terminal to the server.

As a possible implementation manner, after determining that the terminal is a non-campus positioning terminal, the LMF device carries the positioning result of the terminal in a terminal Location result Response Nlmf _ Location _ determination Location Response message, and selects to send the terminal Location result Response message to the public network AMF device, so that the public network AMF device sends the terminal Location result Response message to the GMLC device, and the GMLC device forwards the terminal Location result Response message to the server initiating the positioning request.

Illustratively, the fields included in the terminal location result response message are as shown in table 4 above.

It can be understood that, under the condition that the LMF device determines that the terminal is the non-campus positioning terminal, the public network AMF device and the GMLC device are used for sending the positioning result of the terminal to the server, so that the positioning requirements of all terminals can be met, and the applicability of the communication method provided by the embodiment of the invention is improved.

In some embodiments, as shown in fig. 6, after the LMF device generates the location result of the terminal, it is determined whether the terminal is a campus location terminal or a non-campus location terminal, and when the terminal is a campus location terminal, the location result of the terminal is selected to be sent to the GMLC device in the campus network, so that the location result of the terminal is not transmitted through the public network AMF device, the risk of location result leakage due to forwarding of the location result through the public network AMF device is eliminated, and the location information of the campus location terminal is protected. And under the condition that the terminal is the non-campus positioning terminal, the positioning result of the terminal is selected to be sent to the public network AMF device and forwarded to the server through the GMLC device, so that the requirement that the non-campus positioning terminal realizes positioning through the LMF device is met. Therefore, the communication method provided by the invention not only meets the privacy requirements of the park positioning terminals, but also can realize the positioning requirements of all terminals.

In a design, taking the terminal 12 as a campus positioning terminal as an example, in the campus communication system 10 provided in the embodiment of the present invention, after the terminal 12 is accessed to the public network AMF device 14 through the base station device 11, a subsequent positioning process for the terminal is shown in fig. 7.

And S505, the public network AMF equipment sends a terminal positioning request to the LMF equipment.
