Referring to fig. 1, a schematic structural diagram of a wireless communication system according to an embodiment of the disclosure is shown. As shown in fig. 1, the wireless communication system is a communication system based on a cellular mobile communication technology, and may include: a number of UEs 11 and a number of access devices 12.

Wherein UE11 may be a device that provides voice and/or data connectivity to a user. The UE11 may communicate with one or more core networks via a radio access network (Radio Access Network, RAN), and the UE11 may be an internet of things UE such as a sensor device, a mobile phone (or "cellular" phone) and a computer with an internet of things UE, for example, a fixed, portable, pocket, hand-held, computer-built-in or vehicle-mounted device. Such as a Station (STA), subscriber unit (subscriber unit), subscriber Station (subscriber Station), mobile Station (mobile Station), mobile Station (mobile), remote Station (remote Station), access point, remote UE (remote terminal), access UE (access terminal), user terminal, user agent (user agent), user device (user equipment), or user UE (UE). Alternatively, the UE11 may be an unmanned aerial vehicle device. Alternatively, the UE11 may be a vehicle-mounted device, for example, a laptop with a wireless communication function, or a wireless communication device externally connected to the laptop. Alternatively, the UE11 may be a roadside device, for example, a street lamp, a signal lamp, or other roadside devices having a wireless communication function.

Access device 12 may be a network-side device in a wireless communication system. Wherein the wireless communication system may be a fourth generation mobile communication technology (the 4th generation mobile communication,4G) system, also known as a long term evolution (Long Term Evolution, LTE) system; alternatively, the wireless communication system may be a 5G system, also known as a New Radio (NR) system or a 5G NR system. Alternatively, the wireless communication system may be a next generation system of the 5G system. Among them, the access network in the 5G system may be called NG-RAN (New Generation-Radio Access Network, new Generation radio access network). Or, an MTC system.

Wherein the access device 12 may be an evolved access device (eNB) employed in a 4G system. Alternatively, access device 12 may be an access device (gNB) in a 5G system that employs a centralized and distributed architecture. When the access device 12 employs a centralized and distributed architecture, it typically includes a Centralized Unit (CU) and at least two Distributed Units (DUs). A protocol stack of a packet data convergence protocol (Packet Data Convergence Protocol, PDCP) layer, a radio link layer control protocol (Radio Link Control, RLC) layer, and a medium access control (Media Access Control, MAC) layer is provided in the centralized unit; a Physical (PHY) layer protocol stack is provided in the distribution unit, and the specific implementation of the access device 12 is not limited by the embodiments of the present disclosure.

A wireless connection may be established between access device 12 and UE11 over a wireless air interface. In various embodiments, the wireless air interface is a fourth generation mobile communication network technology (4G) standard-based wireless air interface; or, the wireless air interface is a wireless air interface based on a fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface is a new air interface; alternatively, the wireless air interface may be a wireless air interface based on a 5G-based technology standard of a next generation mobile communication network.

In some embodiments, an E2E (End to End) connection may also be established between UEs 11. Such as V2V (vehicle to vehicle, vehicle-to-vehicle) communications, V2I (vehicle to Infrastructure, vehicle-to-road side equipment) communications, and V2P (vehicle to pedestrian, vehicle-to-person) communications among internet of vehicles communications (vehicle to everything, V2X).

In some embodiments, the above wireless communication system may further comprise a network management device 13.

Several access devices 12 are connected to the network management device 13, respectively. The network management device 13 may be a core network device in a wireless communication system, for example, the network management device 13 may be a mobility management entity (Mobility Management Entity, MME) in an evolved packet core network (Evolved Packet Core, EPC). Alternatively, the network management device may be other core network devices, such as a Serving GateWay (SGW), a public data network GateWay (Public Data Network GateWay, PGW), a policy and charging rules function (Policy and Charging Rules Function, PCRF) or a home subscriber server (Home Subscriber Server, HSS), etc. The embodiment of the present disclosure is not limited to the implementation form of the network management device 13.

The UE accesses the network through a terrestrial cellular system, and typically the radio cell broadcasts a Tracking Area identity (Tracking Area Identification, TAI) of a single Tracking Area (TA) to the UE. The UE accesses the network through a satellite, and the satellite cell supports TAIs broadcasting one or more TAs to the UE due to the altitude of the satellite, beam coverage, etc.

However, in a satellite access scenario, in order to achieve efficient paging of the UE and FA control and/or SAR control of the UE, the gNB needs to send the broadcast TAI to the access management function (Access Management Function, AMF) via NGAP messages. The TA information may include a TAI indicating the TA.

Meanwhile, if the gNB can acquire the TA information corresponding to the position of the UE, the gNB also reports the TAI of the TA where the UE is currently located to the AMF. The AMF constructs a registration area (Registration Area, RA) for the UE according to the broadcast TAI and the TA where the UE is currently located, and performs FA control and/or SAR control on the UE by combining the subscription information and/or local policy of the UE.

The process of performing FA and/or SAR control for a UE may be as follows:

FA control:

if a single or multiple TAIs are broadcast, based on the subscription information of the UE,

when broadcasting a single TAI, determining that the single TAI is contained in the TA indicated by the FA information based on the subscription information of the UE, and rejecting the UE from accessing the network by the AMF;

If a plurality of TAIs are broadcast, based on the user subscription information, the plurality of TAIs are all in the FA information, and the AMF refuses the UE to access the network.

If the AMF refuses the UE to access the network, the UE cannot perform any communication with the network in the TA indicated by the FA information.

If at least one of the broadcasted TAIs is not included in the FA information, the UE may communicate with the network.

SAR control:

if none of the broadcasted TAIs is within the allowed area indicated by the SAR information, the UE is considered to be located within a non-allowed area, and no traffic communication can be initiated between the UE and the network. If at least one of the broadcast TAIs is within the allowed area, the UE is considered to be within the allowed area and may be in any communication with the network.

The FA and/or SAR control process is determined only based on the broadcasted TAIs, and the TAIs reported to the network (AMF) include, in addition to the broadcasted TAIs, the TAIs representing the current location of the UE. The TAI representing the current location of the UE may be a TAI obtained by mapping and converting the information of the location where the UE is actually located by the gNB. The TAI may not actually be included within the broadcast TAI.

As shown in fig. 2, at time T1, the satellite cell broadcasts TAIs of TA1, TA2, and TA5 to the UE, but the location where the UE is actually located is at TA6.

If the TAI representing the actual location of the UE is not included in the broadcast TAI, the broadcast TAI belongs to a TAI of a non-allowed area of SAR according to the related art, traffic communication between the UE and the network device is restricted. But at this time, the UE actually TAI does not belong to the non-allowed area of SAR, and traffic communication between the UE and the network device should be allowed, which results in erroneous control of the UE traffic communication.

Or, the broadcast TAI does not belong to the non-allowed area of the SAR, the UE is allowed to establish a connection with the network and perform service communication, but the actual TAI of the UE belongs to the non-allowed area of the SAR, which should be to limit the service communication between the UE and the network device, so that the UE that is originally to limit the service communication with the network device accesses to the network and communicates with the network device.

Both of the above cases cause erroneous judgment of the movement restriction of the UE. If the AMF performs SAR control or FA control according to the TA where the UE is currently located, the UE cannot sense the change of the TA where the UE is located, so that when the UE is in a non-allowed area of SAR or FA, and network communication is limited, the UE cannot sense when to initiate communication with the network again.

As shown in fig. 3, an embodiment of the present disclosure provides a method for controlling communication between a user equipment UE, which is performed by the UE, and includes:

S310: receiving a first message, wherein the first message comprises area information; the area information indicating an area in which communication between the UE and a network device is prohibited;

s320: determining a first position of the UE;

s330: and controlling communication between the UE and network equipment according to the area information and the first position.

The UE may be a variety of terminals capable of communication, e.g., communication devices capable of camping on non-terrestrial cells (Non Terrestrial Networks, NTN).

The first message may be a non-access stratum (NAS) message sent by the core network device to the UE. The NAS message may be, for example, a NAS message that the core network device rejects the UE to send. The core network device includes, but is not limited to: an access management function (Access Management Function, AMF).

The first message herein may include: area information, which may be used to determine any information of an area where access by the UE is prohibited.

Illustratively, the region information may include, but is not limited to, at least one of:

position information of a center point of the region and an inner diameter or radius of the region;

position information of a plurality of boundary points of the region.

The location information indicates, but is not limited to, latitude and longitude, and/or a relative location with respect to a reference point. The reference point may be any predetermined reference location.

The UE may acquire location information of a first location where the UE itself is located. Illustratively, the UE may determine the first location where itself is located by one or more of:

positioning the UE based on a positioning system to obtain position information of the UE, and positioning the position information of a first position where the UE is located based on a global positioning system (Global Positioning System, GPS) or positioning the position information of the first position where the UE is located based on a beidou system, for example;

or alternatively, the process may be performed,

and positioning the UE based on a triangulation mode and the like, and obtaining the position information of the first position where the UE is located. For example, the UE and/or the base station send a positioning signal, so that the relative position between the UE and the base station can be obtained, and based on the relative position and the position of the base station, the position information of the first position where the UE is located can be obtained.

For example, the UE may periodically determine its own location information, or the UE determines its own location information when detecting a trigger event. For example, when the UE detects that the displacement amount of the UE reaches a preset amount based on the inertial sensor of the UE, the UE determines that a trigger event is detected, or when the UE performs wireless signal measurement, it finds that the signal quality fluctuation value of the wireless signal reaches a preset value, and may also determine that a trigger event is detected.

In still other embodiments, the UE may establish a binding relationship with other devices, for example, the UE may be a wearable device, and the user may also wear other location-capable devices such as a cell phone. Also for example, the UE may be a mobile phone carried by a user, and the other devices having a binding relationship with the mobile phone may include: vehicle-mounted devices, and the like.

In this case, the UE may also receive its own location information from other devices with which a binding relationship is established. For example, the mobile phone locates its own position information, and sends the locating information to the smart band or the smart watch as the position information of the smart band or the first position where the smart band is currently located.

On the one hand, if the UE receives the area information from the network device, the UE will combine the first location of the UE, and if the UE finds that the first location of the UE is located in the area indicated by the area information, the UE will not attempt invalid access or communication any more, thereby saving power consumption of the UE.

For example, if the UE detects that the duration of the UE in the area indicated by the area information reaches the preset duration, the UE may switch from the first state to the second state, where the power consumption of the UE in the first state is higher than the power consumption of the UE in the second state. The first state may be an active state of the UE and the second state may be a dormant state of the UE. The first state may be an on state of the UE, and the second state may be a standby state of the UE, etc. Of course, the above is merely examples, and the specific implementation is not limited to the above examples.

On the other hand, the UE receives the area information from the network equipment and combines the position information of the first position of the UE to determine whether the UE communicates with the network equipment, and the UE controls the communication of the UE by combining the FA information and the SAR information with the TAI broadcasted by the base station, so that the problem of relatively accurately controlling the movement restriction of the UE under the condition of multi-TAI broadcast by the wireless cell when the UE uses satellite access can be solved.

In some embodiments, the S330 may include at least one of:

disabling communication between the UE and the network device when the first location is within the region indicated by the region information;

and when the first position is located outside the area indicated by the area information, allowing communication between the UE and the network equipment.

If the UE receives the area information and finds that the first location where the UE is currently located is located in the area, the operating system or the communication control component of the UE will prohibit communication between the UE and the network device.

If the UE finds that the first location where the UE is currently located is not included in the area after receiving the area information, the communication between the UE and the network device is allowed.

Disabling communication between the UE and the network device herein may include, but is not limited to:

Disabling any communication between the UE and an access network device;

any communication between the UE and the core network device is prohibited.

Allowing communication between the UE and the network device may include:

allowing arbitrary communication between the UE and an access network device;

allowing arbitrary communication between the UE and the core network device.

The access network device herein may include at least a base station, which may be an eNB and/or a gNB.

The core network device may include: AMF, user plane function (User Plane Function, UPF) and/or session management function (Session Management Function, SMF).

Any communication herein may include: traffic communication and/or non-traffic communication. Typical non-traffic communications may include: signaling communications, such as mobility management communications related to UE mobility, etc.

Normally, when the UE receives the area information, the UE is located in the area, and if the UE is located outside the area again, it is indicated that the UE has relatively large displacement, so that communication between the UE and the network device may be allowed, so as to improve the accuracy of UE communication control.

In some embodiments, the region information includes:

location information indicating a second location at which the network device refuses to communicate with the UE;

A distance threshold; wherein the area indicated by the area information includes: a distance from the second location is not greater than a geographic extent of the distance threshold.

The location indicated by the location information may be: the network device (e.g., AMF) refuses to communicate with the UE at the second location where the UE is located.

In an exemplary embodiment, the UE sends NAS request messages such as a registration request message and/or a service request message to the core network device, where the UE may carry location information obtained by positioning itself in the registration request message and/or the service request message, or when the UE sends NAS request messages such as a registration request message and/or a service request message to the core network device through the base station, the base station determines location information of a location where the UE is located at the time, and sends the location information and the NAS message to the core network device together. In this way, the core network device will also acquire the location information of the UE when receiving the NAS message. If the core network device refuses the access of the UE or refuses to provide service to the UE, a refusal message is sent to the UE, and the refusal message carries the area information. The location information included in the area information may be location information of the UE or UE reported by the base station.

The region information may also include a distance threshold. Thus, the range of the second position as the range of the central point of the area indicated by the area information, which is equal to the distance threshold, can be: the area indicated by the area information.

That is, the area indicated by the area information includes: any geographic location having a distance from the second location that is less than or equal to the distance threshold.

The area information may include one or more distance thresholds, for example. When the area information includes a distance threshold, the area indicated by the area information may be a circular area centered on the second location.

When the area information includes a plurality of distance thresholds, different distance thresholds are distance thresholds oriented in different directions with the second position as a center point. The assumed region information may include: 4 distance thresholds, which may correspond to the thresholds of the north-south east and west 4 orientations, respectively, of the second threshold. The distance thresholds for different orientations may be the same or different.

If the region information includes a plurality of distance thresholds, the second location will likely not be the center location of the region indicated by the region information when any two of the distance thresholds are different.

The first message includes: registering the response message; and/or service response messages.

The registration response message is a response message to the registration request message. The registration response message may be a registration reject message, for example.

The service response message may be a response message to a service request message of the UE. The service response message may be a service rejection message, for example.

Thus, in some embodiments, as shown in FIG. 4, the method further comprises:

s300: and sending a second message, wherein the first message is returned based on the second message.

If the second message is a registration request message, the first message is a registration response message;

and if the second message is a service request message, the first message is a service response message.

In some embodiments, the method further comprises:

if the UE moves outside the area indicated by the area information, the UE may try to communicate with the network device again, and if the network device refuses to communicate with the UE again at this time, the UE may receive the area information redetermined by the network device according to the current location of the UE.

In some embodiments, the first message further comprises: timing information for the UE to start a timer; the effective time range of the area information is as follows: the timing range of the timer. And if the timer is overtime, the area information is invalid.

For example, the S330 may include:

starting a timer according to the timing information;

when the timer does not timeout and the UE is located in the area indicated by the area information, prohibiting the UE from communicating with network equipment;

and allowing the UE to communicate with the network equipment when the timer does not timeout and the UE is located outside the area indicated by the area information.

In some embodiments, the method further comprises:

and when the timer is overtime, the second message is resent to the network equipment, and the resent second message is at least used for triggering the network equipment to resend the area information and/or the area information and the timing information.

As shown in fig. 5, an embodiment of the present disclosure provides a UE communication control method, which is performed by a UE, the method including:

s410: receiving a third message, wherein the third message comprises timing information;

s420: starting a timer according to the timing information;

s430: and controlling communication between the UE and the network equipment according to the timing condition of the timer.

The third message may be a NAS message sent by the core network device. The third message may be a rejection message rejecting communication with the UE. The third message includes timing information.

For example, the timing information may indicate at least a timing duration.

Still further illustratively, the timing information may further include: time information of a start time of the start timer.

If the timing information indicates only a timing duration, the UE may start a timer by default for receiving the timing information. If the timing information indicates not only the timing duration but also the time information indicating the starting time, the UE starts the timer at the starting time.

Of course, this is merely an example of timing information, and the specific implementation is not limited to this example.

After receiving the timing information, the UE starts a timer according to the timing information.

After the timer is started, the timing condition of the timer in the time domain can be divided into: the timer does not time out or the timer times out. And if the timer is overtime, the timer is stopped. The timer not timing out indicates that the timer is also running, i.e. within the timing range of the timer.

At this time, the UE controls communication between itself and the network device according to the timing status of the timer.

The communication between the UE and the network device according to the timing condition may include at least one of:

the UE prohibits any communication with the network equipment according to the timing condition;

The UE allows any communication with the network device depending on the timing conditions.

Thus, in some embodiments, the S430 may include at least one of:

disabling communication between the UE and the network device when the timer does not expire;

when the timer expires, communication between the UE and the network device is allowed.

The third message may be any NAS message. Illustratively, the third message includes:

registering the response message;

and/or the number of the groups of groups,

service response message.

The registration response message may be a registration reject message, for example. The registration reject message may also carry a reject reason for the network device to reject the registration request in response to the UE.

Also illustratively, the service response message may be a service rejection message, which may also carry a rejection reason for the network device to reject the service request in response to the UE.

In some embodiments, the third message further comprises: regional information;

the method further comprises the steps of:

when the timer expires, determining whether the UE is located in an area indicated by the area information;

if the UE is located in the area indicated by the area information when the timer times out, prohibiting the communication between the UE and the network equipment, and further, if the UE is located in the area indicated by the area information when the timer times out, retransmitting a fourth message to the network equipment, wherein the fourth message is at least used for triggering the network equipment to retransmit the timing information, or triggering the network equipment to transmit the timing information and the area information;

And if the timer is overtime and the UE is positioned outside the area indicated by the area information, determining to allow the UE to communicate with the network equipment.

As shown in fig. 6, the method further includes:

s400: and sending a fourth message, wherein the third message is returned based on the fourth message.

And if the fourth message is a registration request message, the third message is a registration response message. And if the fourth message is a service request message, the third message is a service response message.

Of course, the third message and the fourth message are merely examples, and the specific implementation is not limited to these examples.

As shown in fig. 7, an embodiment of the present disclosure provides a UE communication control method, which is performed by a network device, the method including:

s510: transmitting a first message to the UE, wherein the first message includes: regional information; the area information indicates an area for prohibiting the UE from communicating with the network equipment;

The network device may include, but is not limited to, an AMF.

The AMF may send a first message to the UE, which may be any NAS message. The first message includes area information, and after the area information is sent to the UE, the UE determines whether to communicate with the network device according to the area information and the current location of the UE.

The region information may be any information describing a specific one of the geographical regions.

The area information may be used to determine any information of an area where access by the UE is prohibited.

position information of a plurality of boundary points of the region.

The location information includes, but is not limited to, latitude and longitude, and/or relative location information with respect to a reference point. The reference point may be any predetermined reference location.

If the UE is located in the area indicated by the area information, the UE does not communicate with the network equipment, if the UE is located outside the area indicated by the area information, the UE tries to communicate with the network equipment, and if the network equipment refuses to communicate with the UE again in the process of trying to communicate with the network equipment, the UE receives the area information which is sent back by the network equipment again.

In some embodiments, as shown in fig. 8, the method further comprises:

In some embodiments, the third message is sent based on a fourth message. The fourth message is sent to the network device by the UE, and after the network device receives the fourth message, if communication with the UE is refused, the third message carrying the timing information may be sent to the UE.

For example, if the fourth message is a registration request message, the third message may be the registration response message. If the fourth message is a service request message, the third message may be the service response message.

As shown in fig. 11, an embodiment of the present disclosure provides a UE communication control method, which is performed by a network device, the method including:

s710: determining timing information;

s720: starting a timer according to the timing information;

s730: and determining whether to communicate with the UE according to the timing condition of the timer.

The timing information may be information such as a timing duration sent to the UE in the third message.

This embodiment may be implemented alone or in combination with any of the previous embodiments.

In some embodiments, the S730 may include:

and receiving a service request sent by the UE.

The S710 determining timing information may include: and determining the timing information according to the subscription data and/or the strategy information of the UE. The policy information may include: the AMF locally stores policy information and/or policy information received from the PCF.

The embodiment of the disclosure also provides a method for performing FA control on the UE, and the corresponding implementation can be applied to SAR control.

The network device performs FA control according to the TA where the UE is currently located, and may include:

the network equipment judges whether the TA where the UE is currently located is contained in the FA according to the subscription information and/or the policy information (for example, the local policy information of the AMF) of the UE;

if the TA where the UE is currently located is not contained in the FA, the communication process can be continued;

if the TA in which the UE is currently located is contained in the FA, the network equipment refuses the UE communication process.

And the network equipment returns a rejection message to the UE according to the judging result. The rejection message may include location information of the location where the AMF rejected the UE when communicating with the UE, and a distance threshold.

The location where the AMF refuses to communicate with the UE where the UE is located may include: the AMF refuses longitude and latitude information of the longitude and latitude where the UE is when communicating with the UE. The latitude and longitude information may include: global navigation satellite system (Global Navigation Satellite System, GNSS) information, or other location information that may represent a UE location and may be processed by the UE.

After the UE receives the rejection message, the location information of the location where the AMF rejects the UE to communicate with the UE and the distance threshold are stored, and any communication between network devices is not started temporarily according to the location information and the distance threshold.

If the UE moves, if the distance between the current location AMF of the UE and the location of the UE when the UE communicates is refused, and when the distance threshold is exceeded, the UE initiates communication with the network device again.

In another embodiment, the reject message contains timing information.

The timing information may be used for the UE to start a timer. After the UE receives the rejection message, the timing information is stored, a timer is started according to the timing information, and the UE does not initiate any communication with the network equipment within the timing range of the timer. Thereafter, if the UE attempts to initiate network communication, the UE determines whether the timer has expired based on the current time, and if the timer has expired, initiates communication with the network device again.

If the timer does not time out, communication with the network device is not initiated. At this time, if the UE forcibly initiates communication with the network device, the network device may refuse the UE to access according to the timer.

And after the UE is successfully accessed to the network, the UE deletes the UE position information, the distance threshold value and/or the timing information when the UE is refused.

The above-described scheme can be used in a plurality of flows of access registration, service request, etc., and is specifically described by the following embodiments.

When the UE accesses the network and initiates initial registration, the AMF judges that all TAs corresponding to the broadcast TAI are contained in the FA according to the broadcast TAI, the AMF returns registration failure to the UE and refuses the UE to access, and the returned message contains the current position information of the UE and the distance threshold value. The UE communication control method may include:

the UE sends a registration request; the registration request includes: access network parameters, registration type, subscriber subscription hidden identity (Subscription Concealed Identifier, sui) or 5G-globally unique temporary user identity (Globally Unique Temporary UE Identification, GUTI), permanent equipment identity (Permanent equipment Identifier, PEI) and requested network slice identity (Network Slice Selection Assistance Information, NSSAI), and if the last accessed TAI is available, further comprises: finally, access the TAI of the TA. Access type indication: if the UE wants to perform an initial registration, a mobile registration update, a periodic registration update, or an emergency update. The TAI of the last access TA is included in the registration request and is available to the AMF to determine the RA of the UE.

AMF selection, for example, after the access network/radio access network ((R) AN) receives the registration request message, AMF is selected.

3. Sending a registration request to the selected AMF; for example, the (R) AN sends AN N2 message to the new AMF, the N2 message containing the N2 parameter, the aforementioned registration request, etc. The N2 parameter contains information related to the cell in which the UE is currently camping, such as the selected public land mobile network ID, location information of the UE, and cell identity.

4. Receiving a UE context transfer (Namf-UEContextTransfer) between a new AMF and an old AMF, wherein the new AMF is the AMF selected in the previous step, and the old AMF is an AMF which provides mobile access management and control for the UE before the new AMF; illustratively, if the UE's AMF changes, the new AMF needs to obtain the UE's user subscription permanent identity (Subscription Permanent Identifier, SUPI) and UE context from the old AMF.

5. An Identity (Identity) request and response are transmitted between the new AMF and the UE.

UE authentication, e.g. information to authenticate the UE is interacted between the new AMF and the authentication server function (Authentication Server Function, AUSF).

7. Information interaction between the new AMF and the UDM, illustratively, after the UE's AMF has changed, if the new AMF does not acquire a valid UE context, the new AMF may select and register with the UDM and acquire user subscription data from the UDM. Illustratively, the user subscription data includes, but is not limited to: access and mobile subscription data, etc. The AMF acquires the subscription information from the UDM, and if the FA in the subscription information contains all the TAAs indicated by the broadcast TAI, the UE needs to be forbidden to be accessed.

8. The new AMF performs access management (Access Management, AM) policy association establishment/update with the policy control function (Policy Control Function, PCF).

9. Protocol data unit (Protocol Data Unit, PDU) session update/release. For example, AMF sends an Nsmf-session update session management context request (Nsmf-PDU-UpdateSMContext Request) to SMF to activate the user plane connection for the PDU session.

10. The new AMF sends a registration reject message to the UE indicating that the UE's registration request is rejected. In an embodiment of the present disclosure, the registration reject message includes: the AMF refuses the position information and the distance threshold value of the position where the AMF is positioned when communicating with the UE; or timing information.

11. The remaining steps of the registration procedure.

When the UE moves, and the distance between the current position of the UE and the position of the UE when the AMF refuses to communicate with the UE exceeds the distance threshold, the UE initiates a network access request again. And after the access is successful, the UE deletes the position information and the distance threshold value, otherwise, the UE temporarily does not initiate an access request to the network equipment.

As shown in fig. 13, an embodiment of the present disclosure provides a UE communication control method, which may include:

for example, after the UE accesses the network and successfully registers with the network, the UE initiates a service request to the network.

And after receiving the service request message, the gNB acquires the TA where the UE is currently located according to the current position information of the UE, and provides the TAI of the TA to the AMF.

At this time, if the AMF determines that although the TA indicated by the broadcast TAI is not all contained by the FA according to the subscription information, the TA where the UE is currently located is located in the FA, the AMF should return a service reject message.

The UE communication control method may include:

the ue initiates a service request and sends a service request (service request) message to the network. For example, after the UE accesses the network and successfully registers with the network, the UE initiates a service request to the network.

And when the gNB receives the service request message, acquiring the TA where the UE is currently located according to the current position information of the UE.

The gNB includes the TAI of the TA where the UE is currently located and the service request message in the N2 message, and sends the TAI and the service request message to the AMF.

And 4, after the AMF receives the N2 message, if the subscription information of the UE does not exist, acquiring the subscription information of the UE from the UDM.

And 5, the AMF judges whether the TA where the UE is currently located is contained in the FA according to the UE subscription information and broadcast TAI, and if the TA where the UE is currently located is located in the FA, the AMF needs to prohibit the UE from communicating with the network whether the TA indicated by the broadcast TAI is contained in the FA or not.

6. Other steps of service request;

The AMF returns a service reject message to the UE, which may contain a reject cause, as well as location information and a distance threshold for the UE location when the AMF rejects communication with the UE. And the network equipment also initiates the de-registration process of the UE.

And 8, the UE stores the position information and the distance threshold information, and temporarily does not establish connection with the network equipment.

When the distance between the current position of the UE and the position of the UE when the AMF refuses to communicate with the UE exceeds a distance threshold value, the UE initiates a network access registration request again. And after the access is successful, the UE deletes the position information and the distance threshold of the position where the UE is when the AMF refuses to communicate with the UE.
