Referring to fig. 1, the movement of a terminal device 110, such as a drone or an autonomous vehicle, may need to be limited to a certain range, which may be referred to as an authorized area, and an area outside the authorized area may be referred to as an unauthorized area or a restricted area. As shown in fig. 1, a PDU session-1 is established between the terminal device 110 and the management server 120, the management server 120 may be a remote server of a private agency, and the terminal device 110 is controlled by the management server 120. When the terminal device 110 moves to an unauthorized area, data transmission with the management and control server 120 still needs to be maintained, so that on one hand, the management and control server 120 can continue to control the terminal device 110 to fly or drive; on the other hand, it is enabled to transfer the control right of the terminal device 110 to a node in the jurisdiction of the unauthorized area, for example, when the terminal device 110 moves to the unauthorized area, it is necessary that the management server 120 may continue to control the terminal device 110 to fly or drive, or may move the control right to a node in the jurisdiction of the unauthorized area, for example, the management server 130.

Therefore, it is required that the terminal device 110 maintains a specific communication connection (e.g., PDU session-1) while in the unlicensed region, or establishes a specific communication connection in the unlicensed region to communicate with the regulation server 130 of the unlicensed region, for example, to establish a PDU session-2 with the regulation server 130. PDU session-1 may be released after the regulation server 130 has completely taken over the terminal device 110 (but not immediately after the terminal device 110 has moved into the unlicensed region), e.g., after PDU session-1 is released after the PDU session-2 established between the terminal device 110 and the regulation server 130 is successful.

In the current technical solution, when the terminal device 110, such as the drone, moves to an unauthorized area, all session connections are broken, which makes it difficult to control the terminal device in the unauthorized area.

Based on the above, the embodiments of the present application provide a communication control method, where restricted data communication is performed in a first area, where the restricted data communication includes allowing a terminal device to perform data transmission using a part of an established session; and/or allow the terminal device to establish a specific session for data transfer. According to the technical scheme of the embodiment of the application, by introducing restrictive data communication on the first area, that is, allowing the terminal device to use part of the established session for data transmission in the first area, or allowing the terminal device to establish a specific session for data transmission, the terminal device can maintain or newly establish a specific communication connection on the first area for data communication, so that the terminal device in the first area can be conveniently controlled, and the terminal device is prevented from losing control in the first area.

After the UE accesses the 5G network through the Uu port, the PDU session data connection from the UE to the UPF is established under the control of the SMF, and therefore data transmission is carried out. The system also has an NEF function for interfacing with a third party application server and transferring information between the core network node and the third party application.

The communication control method provided in the present application is explained in detail by several specific embodiments.

Fig. 4 is a flowchart illustrating a first embodiment of a communication control method according to an embodiment of the present application. The communication control method may be applied to an electronic device, and includes step S410.

In step S410, the electronic device performs restricted data communication in the first area, the restricted data communication including allowing the electronic device to perform data transmission using part of the established session; and/or allow the electronic device to establish a particular session for data transfer.

In an example embodiment, the first area is a restricted area, and the electronic device performs restricted data communication in the first area, where the restricted data communication means that the data communication of the electronic device in the first area is restricted, for example, only the electronic device is allowed to perform data transmission with the server 1 using part of the established session, for example, session-1; and/or only allow the electronic device to establish a particular session with the server 2, e.g., session 2, for data transfer. Taking the drone as an example, after the drone flies into the first area, i.e., the restricted area, the drone is only allowed to use the established session with the drone Management center (UTM), and/or the electronic device is only allowed to establish a session with the authoritative third-party entity TPAE for data transmission.

It should be noted that, in an example embodiment, "specific" may mean determined according to a type of the electronic device, for example, the specific session may be a session determined for the type of the electronic device in the first area, for example, a session for communication between the drone and a drone control server of a public security system, a session for communication between the autonomous vehicle and a vehicle control server of a traffic management system, or other suitable forms of sessions, which is not particularly limited in this application.

The electronic device may determine the specific session according to the specific session related information or local configuration sent by the network device side. For example, the network device side may set different specific sessions for different electronic device types in the first area, and send information related to the specific sessions to the electronic device according to the types of the electronic devices. The electronic device may also configure a specific session corresponding to the type of the electronic device locally, and determine the specific session to be established according to the local configuration after moving to the first area.

Further, in an example embodiment, the electronic device performs data communication normally in the second area, where the second area is another area outside the restricted area, and the performing data communication normally may be performing establishment and modification of a PDU session according to a procedure specified by 3GPP, and transmitting user plane data. The partially established session is a session established in the second area.

It should be noted that the electronic device may be a terminal device such as a mobile phone, an unmanned aerial vehicle, or an autonomous vehicle, and may also be other suitable electronic devices such as a base station, which is also within the protection scope of the present application.

According to the technical solution in the example embodiment of fig. 4, by introducing restrictive data communication on the first area, that is, only allowing the electronic device to use a part of the established session for data transmission in the first area, or allowing the electronic device to establish a specific session for data transmission, the electronic device can maintain or newly establish a specific communication connection on the first area for data communication, so that the electronic device in the first area can be conveniently controlled, and the electronic device is prevented from losing control in the first area.

In an example embodiment, the second zone is an authorized zone and the first zone is an unauthorized zone. In the authorization area, the electronic device may normally establish and use multiple connections (e.g. multiple PDU sessions) of the user plane for data communication, and the establishment and use of the connections may be the same as the existing 3GPP mechanism; the electronic device allows use of only a portion of the established PDU session in the unlicensed region. Part of the established PDU session may be used for communication of a specific server; and/or the electronic device moves to an unauthorized area, allowing a particular PDU session to be established. A particular PDU session may be used for communication for a particular server.

It should be noted that, in an example embodiment, the specific server may be a server determined according to the type of the electronic device, for example, for the drone, the specific server may be a server of the UTM; for autonomous vehicles, the specific server may be a vehicle control server of a traffic management system.

Further, after the electronic device moves from the second area to the first area, the maintained communication connection, e.g., session-1, may be released later, e.g., after session-2 is established between the electronic device and the server 2, or the server 2 takes over control of the electronic device and then releases the maintained communication connection, i.e., session-1.

In addition, in some embodiments, the electronic device may also be a base station, and the terminal device may access the new base station by means of handover, or the terminal device may access the new base station by means of cell reselection, cell selection, or redirection. When the terminal device is accessed to the new base station from the original base station, i.e. the electronic device, the new base station can acquire the second information and/or the fourth information from the electronic device; or the new base station may obtain the second information and/or the fourth information from the terminal device.

Wherein the second information comprises at least one of the following information: whether to open restrictive data communication for the electronic device; authorized area and/or unauthorized area information. It should be noted that, in the exemplary embodiment of the present application, the content format of the second information is not limited, but the second information may indicate at least one of the above information.

The fourth information includes at least one of: the session is allowed or required to be released or deactivated in an unauthorized area; which QoS data flow or flows in the session are allowed or need to be released or deactivated in the unlicensed region; the session is allowed or needs to be reserved in an unauthorized area; which QoS data flow or flows in the session are allowed or need to be reserved in the unlicensed region. "reserved" may mean that the session or at least one QoS data flow in the session is allowed or required not to be released or activated in an unlicensed region, and data communication may also be performed normally as in an unlicensed region.

It should be noted that, in the exemplary embodiment of the present application, the content form of the fourth information is not limited, but the fourth information may indicate at least one of the above information, and the fourth information may further carry specific session identification information and/or identification information of a QoS data flow.

Referring to fig. 5, in step S510, the terminal device normally performs data communication in the authorized area.

In an example embodiment, the normal data communication may be to perform the establishment, modification and transmission of user plane data of a PDU session according to the procedures specified by 3GPP, for example, to normally establish, activate or maintain multiple session connections. Referring to fig. 5, the terminal device establishes a PDU session normally with the regulation server 1 and a plurality of other servers, for example, the PDU session-1 is established normally between the terminal device and the regulation server 1.

In step S520, the terminal device maintains a part of the established connection in the unauthorized area, and/or establishes a specific connection.

In an example embodiment, the terminal device moves from the authorized area to the unauthorized area, maintains a partially established session connection in the unauthorized area, for example, maintains a session connection with the regulation server 1, i.e., PDU session-1, and releases the session connection with other servers.

According to the technical solution in the example embodiment of fig. 5, the session connection that is partially established is maintained, so that an uncontrolled situation caused by a sudden disconnection of the communication connection when the terminal device enters an unauthorized area can be avoided.

Further, the terminal device may also establish a specific connection, for example, establish a session connection with the regulation server 2, i.e. PDU session 2. The specific connection is a connection for more reasonable control of the terminal device in an unauthorized area, for example the specific connection may be a connection for communication between a drone and a drone control server of a public security system, or a connection for communication between an autonomous vehicle and a vehicle control server of a traffic management system.

It should be noted that, after the terminal device moves to the unauthorized area, the maintained communication connection, for example, PDU session-1, may be released later, for example, after PDU session-2 is established between the terminal device and the regulation server 2, or after the regulation server 2 takes over control of the terminal device, the maintained communication connection is released.

On the basis of the above embodiments, the following describes in detail an implementation scheme of a specific application process of the communication control method by using several specific embodiments with reference to the accompanying drawings.

It should be noted that, in the exemplary embodiment of the present application, the content form of the first information is not limited, but the first information may indicate at least one of the above information.

It should be noted that the restrictive data communication means that the data communication of the terminal device in the unauthorized area is restricted, for example, the terminal device is allowed to use part of the established session to perform data transmission with the network device; and/or allow the terminal device to establish a specific session with the network device for data transmission. Taking the drone as an example, after the drone flies into the unauthorized area, the drone is allowed to use the established session with the drone Management center (UTM), and/or the terminal device is allowed to establish the session with the TPAE for data transmission.

In step S620, the core network interacts with the UDM and/or the PCF, and the interaction information may include the first information.

In an example embodiment, a network element of a core network, such as an AMF, interacts with a UDM and/or a PCF, the interaction message includes first information, for example, the interaction message includes subscription information and/or policy information, and the subscription information and/or policy information includes the first information.

It should be noted that, in step S610 and step S620, the first information may be added only in one step, for example, the first information is added only in the registration request in step S610, or the first information is added only in the subscription information and/or the policy information in step S620, or the first information may be added in both steps, where the added first information includes a parameter providing part or all of the first information, and when the contents of the parameter of the first information in both steps conflict, the core network, for example, AMF, determines which step of the first information content is used.

In step S630, the core network sends second information to the access network, and the second information may be determined based on the interworking information in step S620 and/or the registration request in step S610.

In an example embodiment, the second information includes at least one of: whether restrictive data communication is opened for the terminal equipment or not; authorized area and/or unauthorized area information. The core network element AMF sends the second information to the access network RAN via an N2 interface request, where the N2 interface request includes the second information.

It should be noted that, in the exemplary embodiment of the present application, the content form of the second information is not limited, but the second information may indicate at least one of the above information.

In step S640, the core network sends a registration reply to the terminal device, where the registration reply may include the second information.

In an example embodiment, the core network element, e.g. the AMF, sends a registration reply to the terminal device over the N1 interface, the registration reply including the second information.

It should be noted that, in some example embodiments, step 630 and step 640 may be combined into one step, that is, the message that carries the N2 interface in step 630 and is sent to the access network RAN also carries a registration reply, that is, a NAS message, which is sent to the terminal device, and after receiving the message in step 630, the RAN passes the registration reply, that is, the NAS message, through to the terminal device.

Furthermore, in an example embodiment, the terminal device or UDM/PCF may also provide an indication to the core network that "no authorized or unauthorized areas are defined for the terminal device, i.e. no valid area for user plane data connections is defined.

It should be noted that there is no necessary causal relationship between the first information and the second information, that is, the second information may be sent to the base station and/or the terminal even if the core network, such as the AMF, does not receive the first information of the terminal or the UDM/PCF, or the core network, such as the AMF, only receives the first information from the terminal and/or the UDM/PCF, and does not need to send the second information to the base station and/or the terminal.

Example four

In this embodiment, the terminal device may add the third information to a NAS message (such as a session establishment/modification request) during a session establishment/modification process, and/or a core network element (e.g., SMF) obtains the third information from mutual information of the UDM or PCF, where the third information includes at least one of the following information:

-requesting that the session is allowed or needs to be released or deactivated in an "unlicensed area";

-requesting that the session is allowed or needs to be reserved in "unlicensed areas";

-requesting which QoS data flow or flows in the session are allowed or need to be released or deactivated in the "unlicensed region";

-requesting which QoS data flow or flows in the session are allowed or need to be reserved in the "unlicensed region".

"reserved" may mean that the session or at least one QoS data flow in the session is allowed or required not to be released or activated in an unlicensed region, and data communication may also be performed normally as in an unlicensed region.

It should be noted that only one of the NAS message and the interaction information of the UDM/PCF may include the third information, that is, the NAS message includes the third information, or the interaction information of the UDM/PCF includes the third information.

The core network element may add fourth information to the "session establishment request" message sent to the base station and/or the NAS reply message (e.g., session establishment reply) sent to the terminal device, where the fourth information is used to indicate whether the behavior requested in the third information is approved (corresponding to the four pieces of request information in the above third information).

Referring to fig. 7, in step S710, the terminal device sends third information to the core network during the session establishment or modification process.

In an example embodiment, third information may be added to the NAS message of the session establishment/modification request, where the third information includes at least one of the following information:

It should be noted that, in the exemplary embodiment of the present application, the content form of the third information is not limited, but the third information may indicate at least one of the above information, and the third information may further carry specific session identification information and/or identification information of a QoS data flow.

In step S720, the core network interacts with the UDM and/or the PCF, and the interaction message may include a third message.

In an example embodiment, a core network element (e.g., SMF) interacts with the UDM and/or PCF, and obtains a third message from the interaction message, where the interaction message includes subscription information and/or policy information, and the subscription information and/or policy information includes the third message.

It should be noted that only one of the NAS message in step S710 and the interworking information in step S720 may include the third information, that is, the NAS message includes the third information, or the interworking information of the UDM/PCF includes the third information. The first information may be added in both steps, including a parameter providing part or all of the first information, and in case the parameter content of the first information in both steps conflicts, the core network, e.g. SMF, decides which step of the first information content to use.

In step S730, the core network may add fourth information in a "session request" message sent to the access network. The fourth information is used for indicating at least one of the following information:

-the session is allowed or needs to be released or deactivated in "unlicensed areas";

-the session is allowed or needs to be reserved in "unlicensed areas";

-which QoS data flow or flows in the session are allowed or need to be released or deactivated in the "unlicensed region";

-which QoS data flow or flows in the session are allowed or need to be reserved in the "unlicensed region".

It should be noted that the fourth information may be obtained based on the third information, or may be generated by the core network element itself, which is not limited in this application.

In an example embodiment, the core Network element may determine the content of the fourth Information according to Single-Network Slice Selection service Information (S-NSSAI) and/or DNN corresponding to the PDU session. Adding the determined fourth information to a session setup request to the access network RAN.

In step S740, the core network may add fourth information to the session reply message of the sending terminal device.

In an example embodiment, the core network element, e.g. SMF, adds the fourth message to the NAS message of the session establishment reply message sent to the terminal device.

It should be noted that step S730 and step S740 may be combined into one step, that is, the session establishment request sent to the RAN in step S730 also carries a session establishment reply (such as session accept or reject) sent to the terminal device, and after receiving the message in step S730, the RAN transmits the session establishment reply, that is, the NAS reply message, to the terminal device.

It should be noted that there is no necessary causal relationship between the third information and the fourth information, that is, the fourth information may be sent to the base station and/or the terminal even if the core network, for example, the SMF, does not receive the third information of the terminal or the UDM/PCF, or the core network, for example, the SMF, only receives the third information from the terminal and/or the UDM/PCF, and does not need to send the fourth information to the base station and/or the terminal.

EXAMPLE five

In this example embodiment, the terminal device is outside the "authorized zone", i.e. the unlicensed zone, allowing only specific PDU sessions to be reserved and may also allow specific PDU sessions to be established. The specific PDU session may be a session determined for the type of the terminal device in the unlicensed area, for example, a session between a drone and a drone control server of a public security system, a session between an autonomous vehicle and a vehicle control server of a traffic management system.

In order to establish a specific PDU session, in this exemplary embodiment, fifth information is introduced during the session establishment and/or modification, for example, the fifth information may be added in a NAS message (such as a session establishment/modification request), and/or obtained by a core network element (e.g., SMF) through interaction information of the UDM or PCF, and may include at least one of the following information:

-requesting that the session be established, modified or activated in an unauthorized area;

-which QoS data flow or flows in the session are requested to be established, modified or activated in the unlicensed area.

It should be noted that, in the exemplary embodiment of the present application, the content format of the fifth information is not limited, but the fifth information may indicate at least one of the above information, and the fourth information may further carry specific session identification information and/or identification information of a QoS data flow.

For example, the fifth information may include: requesting that the session be established, modified or activated in the event that the terminal device moves from an authorized area to an unauthorized area; and/or which QoS data flow or flows in the session are requested to be established, modified or activated in case the terminal device moves from an authorized area to an unauthorized area;

the fifth information is used to indicate that the session is established, modified or activated in an unauthorized area. The fifth information may include NAS information (PDU session establishment/modification request) sent by the terminal device, or the core network element may obtain the interaction information from the UDM or the PCF, which is similar to step S710 and step S720, and is not described herein again.

Further, the core network element (e.g. SMF) may determine whether to allow the corresponding PDU session establishment, modification or activation according to the fifth information. For example, the core network element may determine to establish, modify or activate the corresponding session in the unlicensed region according to the fifth information.

In addition, in some example embodiments, the terminal device may carry the third information or the fifth information in the session establishment/modification request message, and further, the terminal device may obtain sixth information from the network device side, where the sixth information includes at least one of the following information:

(1) which PDU session(s) or QoS data flow(s) are allowed or needed to remain in the "unlicensed region";

(2) which PDU sessions or QoS data flows are allowed or need to be released or deactivated in the "unlicensed region";

(3) which PDU sessions or QoS data flows need to be established, modified or activated in the "unlicensed region";

(4) which PDU sessions or QoS data flows are allowed to be established, modified or activated in the "unlicensed region".

It should be noted that, in the exemplary embodiment of the present application, the content form of the sixth information is not limited, but the sixth information may indicate at least one of the above information, and the sixth information may further carry specific session identification information and/or identification information of a QoS data flow.

For example, the sixth information may include: which PDU sessions or QoS data flows must be established, modified or activated in case of movement from "authorized area" to "unauthorized area"; and/or which PDU sessions or QoS data flows are allowed to be established, modified or activated in case of movement from "authorized area" to "unlicensed area";

further, in an exemplary embodiment, when the terminal device is in the "authorized area", it may determine whether the "third information" or the "fifth information" needs to be added to the NAS message sent to the network device according to the content of the "sixth information". The NAS message may be a registration request message or a session establishment request message.

In addition, when the terminal is in the "unlicensed region", it may determine whether to establish, modify, or activate a corresponding PDU session according to the contents of items (3) and (4) of the above-mentioned "sixth information".

It should be noted that the PDU session may be described by PDU session attribute parameters such as S-NSSAI, DNN, PDU session type, SSC-Mode, etc.), as shown in the following path Selection Descriptor (Route Selection Descriptor) table 2.

In some example embodiments, the sixth information may be sent to the terminal device through a NAS message, where the NAS message may be a "registration reply," a "terminal Configuration Update Request (UE Configuration Update Request," or the like message.

In other embodiments, the sixth information may be implemented by extending a terminal Route Selection Policy (URSP) rule of the terminal device, that is, adding "sixth information" to the Policy rule of the URSP, as shown in table 1 below:
