All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

Referring to fig. 1, movement of a terminal device 110, such as a drone or an autopilot, 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 and control server 120, the management and control server 120 may be a remote server of a civil organization, and the terminal device 110 is controlled by the management and control 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 continuously control the terminal device 110 to fly or drive; on the other hand, to enable transfer of control of the terminal device 110 to a node in the jurisdiction of an unauthorized area, for example, when the terminal device 110 moves to an unauthorized area, the need arises for the management server 120 to continue to control the terminal device 110 to fly or drive, or to move control to a node in the jurisdiction of an unauthorized area, such as the management server 130.

Thus, it is desirable that the terminal device 110 still maintain a specific communication connection (e.g., PDU session-1) in the unlicensed region or establish a specific communication connection in the unlicensed region to communicate with the management server 130 in the unlicensed region, such as establishing PDU session-2 with the management server 130. PDU session-1 may be released after the administration server 130 has completely taken over the terminal device 110 (but not immediately after the terminal device 110 has moved to an unlicensed area), e.g., PDU session-1 may be released after successful establishment of PDU session-2 between the terminal device 110 and administration server 130.

In the present solution, when the terminal device 110, for example, the drone, moves to the unauthorized area, all session connections are broken, which makes it difficult to control the terminal device in the unauthorized area.

Based on the foregoing, an embodiment of the present application provides a communication control method, in which a limited data communication is performed in a first area, the limited data communication including allowing a terminal device to perform data transmission using a partially established session; and/or allowing the terminal device to establish a specific session for data transmission. According to the technical scheme of the embodiment of the application, the terminal equipment can keep or newly establish a specific communication connection on the first area to perform data communication by introducing the restricted data communication on the first area, namely allowing the terminal equipment to perform data transmission by using part of established sessions or allowing the terminal equipment to establish a specific session in the first area, so that the terminal equipment in the first area can be conveniently controlled, and the terminal equipment is prevented from losing control in the first area.

The communication control method provided by the application is described in detail below through several specific embodiments.

Fig. 4 is a schematic flow chart 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 the communication control method includes step S410.

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

In an example embodiment, the first area is a limited area, and the electronic device performs a limited data communication in the first area, where the limited data communication means limiting the data communication of the electronic device in the first area, for example, allowing the electronic device to perform data transmission with the server 1 using only a part of the established session, for example, session-1; and/or only allow the electronic device to establish a specific session with the server 2, e.g. session-2 for data transfer. Taking the unmanned aerial vehicle as an example, after the unmanned aerial vehicle flies into a first area, namely a limited area, only the unmanned aerial vehicle is allowed to use an established session with the unmanned aerial vehicle management center (Unmanned Aerial System Traffic Management, UTM) and/or only the electronic equipment is allowed to establish a session with the authoritative third party entity TPAE for data transmission.

It should be noted that, in an exemplary embodiment, "specific" may mean that the specific session is determined according to the 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 unmanned aerial vehicle and the unmanned aerial vehicle control server of the public security system, a session for communication between the autonomous vehicle and the vehicle control server of the traffic management system, or another suitable form of session, which is not particularly limited in this regard.

The electronic device may determine the specific session according to the specific session related information or the 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 type of the electronic device. The electronic device may also locally configure a specific session corresponding to the type of electronic device, and determine a 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 a second area, where the second area is another area outside the limited area, and the normal data communication may be to perform establishment and modification of a PDU session according to a procedure specified by 3GPP, and transmit 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 automatic driving vehicle, or may be other suitable electronic devices, such as a base station, which is also within the scope of the present application.

According to the technical solution in the exemplary embodiment of fig. 4, by introducing the restricted data communication in the first area, that is, allowing the electronic device to use only 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 controlled conveniently, and the electronic device is prevented from losing control in the first area.

In an example embodiment, the second area is an authorized area and the first area is an unauthorized area. In the authorization area, the electronic device can normally establish and use a plurality of connections (such as a plurality of PDU sessions) of the user plane to perform data communication, and the establishment and the use of the connections can be the same as the existing 3GPP mechanism; the electronic device allows use of only part of the established PDU session in the unlicensed area. Part of the established PDU session may be used for server-specific communications; and/or allowing a particular PDU session to be established when the electronic device moves to an unlicensed region. 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 a type of the electronic device, for example, for an unmanned aerial vehicle, the specific server may be a server of UTM; for an autonomous vehicle, the particular server may be a vehicle control server of the traffic management system.

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

In addition, in some embodiments, the electronic device may also be a base station, and the terminal device may access the new base station through a handover manner, or the terminal device may access the new base station through a cell reselection, a cell selection, or a redirection manner. Under the condition that the terminal equipment is accessed to a new base station from an original base station, namely the electronic equipment, the new base station can acquire second information and/or fourth information from the electronic equipment; or the new base station may obtain the second information and/or the fourth information from the terminal device.

Wherein the second information includes at least one of: whether to open a restricted data communication for the electronic device; information of authorized areas and/or unauthorized areas. 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-described information.

The fourth information includes at least one of the following: sessions are allowed or required to be released or deactivated in unauthorized areas; 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 may also be normally conducted as in an licensed 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 foregoing information, and the fourth information may further carry specific session identification information and/or identification information of QoS data flows.

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

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

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

In an example embodiment, the terminal device moves from an authorized area to an unauthorized area where a partially established session connection is maintained, e.g. a session connection with the management server 1, i.e. PDU session-1, is maintained, and a session connection with the other servers is released.

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

Further, the terminal device may also establish a specific connection, e.g. establish a session connection with the management server 2, i.e. PDU session-2. The specific connection is a connection for more rational control of the terminal device in an unauthorized area, for example, the specific connection may be a connection for communication between the unmanned aerial vehicle and an unmanned aerial vehicle 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 the maintained communication connection, e.g. PDU session-1, may be released later after the terminal device moves to the unlicensed area, e.g. after the PDU session-2 is established between the terminal device and the management server 2, or after the management server 2 takes over the control of the terminal device.

On the basis of the above embodiments, the implementation scheme of the communication control method in the specific application process is described in detail below through several specific embodiments with reference to the accompanying drawings.

-requesting to open a restricted data communication;

-authorized area and/or unauthorized area information. Wherein the information of the authorized and/or unauthorized areas may be described by global positioning system (Global Positioning System, GPS) information, cell identification information, tracking area identification (Tracking Area Identity, TAI) information, etc.

The core network element (e.g., AMF) may interact with the UDM and/or PCF, and the interaction information may include the first information.

Further, the core network element determines second information based on the NAS message and/or the interaction message, and sends the second information to the terminal and/or the access network, for example, the base station, where the second information includes at least one of the following information:

-whether to open a restricted data communication for the terminal device;

-information of authorized areas and/or unauthorized areas. Wherein the information of the authorized and/or unauthorized areas may be described by GPS coordinates, cell identification, TAI table, etc.).

Referring to fig. 6, in step S610, the terminal device transmits a registration request to the core network during registration, where the registration request may include first information.

In an example embodiment, the first information may be used to indicate at least one of: request to open the information of the restrictive data communication; authorized region and/or unauthorized region information. The terminal device may send a registration request, e.g. a NAS message, to the core network by adding the first information to the registration request. The information of the authorized and/or unauthorized areas may be described by GPS coordinates, cell identification information, tracking area identification (Tracking Area Identity, TAI) information, etc.

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-described information.

It should be noted that the limiting data communication means limiting data communication of the terminal device in an unauthorized area, for example, allowing the terminal device to perform data transmission with the network device using a partially established session; and/or allowing 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 an unauthorized area, only the drone is allowed to use the established session with the drone management centre (Unmanned Aerial System Traffic Management, UTM) and/or only the terminal device is allowed to establish a session with the TPAE for data transmission.

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

In an example embodiment, a core network element, such as an AMF, interacts with the UDM and/or the PCF, and 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.

In step S610 and step S620, the first information may be added only in one step, for example, the first information may be added only in the registration request in step S610, or the first information may be added only in the subscription information and/or the policy information in step S620, or the first information may be added in both steps, and the first information may be added in a manner that includes parameters providing part or all of the first information, and in a case where the parameter contents of the first information in both steps conflict, the first information contents of which step is used may be determined by the core network, for example, the AMF.

In step S630, the core network sends second information to the access network, which may be determined based on the interaction 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 to open the restricted data communication for the terminal device; information of authorized areas and/or unauthorized areas. The core network element AMF sends second information to the access network RAN through 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-described 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, a core network element, such as an 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 exemplary embodiments, step 630 and step 640 may be combined into one step, that is, in step 630, the message sent to the access network RAN by the N2 interface also carries a registration reply, that is, a NAS message, sent to the terminal device, and after receiving the message in step 630, the RAN transparently transmits the registration reply, that is, the NAS message, to the terminal device.

Furthermore, in an example embodiment, the terminal device or the UDM/PCF may also provide an indication to the core network that an authorized or unauthorized area is not defined for the terminal device, i.e. that the active area of the user plane data connection is not defined.

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

In this embodiment, the terminal device may add third information to the NAS message (such as a session establishment/modification request) during the session establishment/modification process, and/or the core network element (for example, SMF) obtains the third information from the interaction 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 required to be released or deactivated in an "unauthorized area";

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

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

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

"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 may also be normally conducted as in an licensed 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 in 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 requested behavior in the third information is approved (corresponding to the four pieces of request information in the third information above).

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

In an example embodiment, third information may be added in the NAS message of the session establishment/modification request, the third information including 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 QoS data flows.

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

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

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 parameters providing part or all of the first information, and in case of a conflict of the parameter contents of the first information in both steps, the core network, e.g. the 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 to indicate at least one of the following:

-the session is allowed or required to be released or deactivated in an "unauthorized area";

-the session is allowed or required to be reserved in an "unlicensed area";

which QoS data flow or flows in the session are allowed or required 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 area".

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 particularly limited in the present 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 (Single-Network Slice Selection Assistance Information, S-nsai) and/or DNN corresponding to the PDU session. The determined fourth information is added to the session establishment request issued to the access network RAN.

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

In an example embodiment, the core network element, e.g. the SMF, adds the fourth message in 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, step S730 carries a session establishment request sent to the RAN and also carries a session establishment reply (such as session accept or reject) sent to the terminal device, and after receiving the message of step S730, the RAN transparently 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, even if the core network, for example, the SMF, does not receive the third information of the terminal or the UDM/PCF, the fourth information may be sent to the base station and/or the terminal, or the core network, for example, the SMF, receives only 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 "licensed region", i.e. the unlicensed region, only allows for reservation of a specific PDU session and may also allow for establishment of a specific PDU session. The specific PDU session may be a session determined for the type of the terminal device in an unauthorized 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 example embodiment, fifth information is introduced during session establishment and/or modification, for example, fifth information may be added in a NAS message (such as a session establishment/modification request), and/or the core network element (e.g. SMF) obtains fifth information from the interaction information of the UDM or PCF, where the fifth information may include at least one of the following information:

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

-requesting which QoS data flow or flows in the session are 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 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 QoS data flows.

For example, the fifth information may include: requesting that the session be established, modified or activated in case 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 be included in a NAS message (PDU session establishment/modification request) sent by the terminal device, or the core network element is obtained from the interaction information of the UDM or PCF, which is similar to step S710 and step S720, and will not be described herein.

Further, the core network element (e.g. SMF) may determine whether to allow the corresponding PDU session to be established, modified or activated 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 based on the fifth information.

Furthermore, 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 sessions or QoS data flows are allowed or required to remain in the "unlicensed region";

(2) Which PDU sessions or QoS data flows are allowed or required 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 QoS data flows.

For example, the sixth information may include: which PDU sessions or QoS data flows must be established, modified or activated in case of moving from an "authorized area" to an "unauthorized area"; and/or which PDU sessions or QoS data flows are allowed to be established, modified or activated in the event that they move from an "authorized zone" to an "unauthorized zone";

further, in the example embodiment, when the terminal device is in the "authorized area", it may be determined whether "third information" or "fifth information" needs to be added in the NAS message sent to the network device according to the content of the above "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 be determined whether to establish, modify, or activate the corresponding PDU session according to the contents of the (3) th and (4) th pieces of the above-described "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 transmitted to the terminal device through a NAS message, which may be a message of "registration reply", "terminal configuration update request (UE Configuration Update Request)", or the like.

In other embodiments, the sixth information may be implemented by extending a terminal path selection policy (UE Route Selection Policy, urs p) rule of the terminal device, i.e. adding "sixth information" to the policy rule of urs p, as shown in table 1 below:

table 1 UE path selection policy rules
