For example, the PEMC in fig. 2 may be the UE 101 in fig. 1.

The PEGC in fig. 2 has a gateway function, which is a transit node of the PIN and the network, and is responsible for delivering a message from the network (e.g. a core network device) to the PEMC or the PIN on the one hand, for example, receiving a message from a network element through the RAN 102, for example, the PEGC may send a session establishment request message through the RAN, where the session establishment request message includes a PIN ID; on the other hand, messages of PINE or PEMC may be delivered to the network (e.g., core network device). For example, a message of PINE or PEMC may be delivered to the network through the RAN. For example, the UE 101 in FIG. 1 may be the PEGC in FIG. 2.

The pins of fig. 2 may communicate with each other, or may also communicate with PEGC, or may also communicate with PEMC. The communication of the PINE with other devices may be a device-to-device (D2D) communication, such as a PC5 connection communication, a bluetooth communication, or a wireless fidelity (wireless fidelity, wiFi) communication, but may also be a 3 GPP-based communication. The PINE may be the UE 101 in fig. 1 as well, and the UE 101 may be a 3GPP terminal device or a non-3 GPP terminal device.

In an embodiment of the present application, fig. 2 may provide PIN related services. Alternatively, the PIN related service may be a service obtained from the application server by establishing a protocol data unit (protocol data unit, PDU) session through the user plane device after PEGC access to 5GC and using the established PDU session. After the PEGC obtains the data of the service, the service data may be assigned to at least one of PINE, PEGC, or PEMC as shown in fig. 2. The user plane device may be the UPF 103 shown in fig. 2.

The PEMC in fig. 2 may have a PIN function as a PIN, as well as a PIN management function. Similarly, PEGC may have a PIN function as a PIN, in addition to a PIN gateway function.

In some embodiments, PEMC and PEGC are 5GC access capable user devices that can access 5GC through 3GPP access technology or non-3GPP access technology. A connection is established between the PEGC and the PEMC based on the PC5 interface. PEMC is a management node in a PIN network, has 5GC access capability, and can access 5GC independently. PEGC is a gateway node in a PIN network, which also has 5GC access capability, so 5GC can also be accessed and registered independently.

After the terminal device obtains a certain service, if the terminal device does not need the service, but the core network device still provides the service for the terminal device, the resource waste is caused, so how to stop the service of the terminal device by the network device is a problem to be solved.

For example, the terminal device may be the UE 101 of FIG. 1 or the PEGC of FIG. 2.

In the embodiment of the present application, the first core network device may determine whether to stop the terminal device from acquiring the first service according to whether the first parameter of the terminal device meets the first condition indicated by the first condition information of the first service. If the first parameter does not meet the first condition indicated by the first condition information of the first service, the first core network device sends first information, and the first information is used for stopping the terminal device from acquiring the first service.

The terminology used in the embodiments of the present application is described below.

Independent networking non-public network (SNPN)

The SNPN is independent of the public land mobile network (public land mobile network, PLMN), and the operator can operate the SNPN, that is, the core network device of the SNPN is PLMN independent, and the core network device of the SNPN is operated independently by the operator. When the terminal device needs to access the SNPN, the terminal device may enter an SNPN access mode (access mode).

Non-public network of non-independent networking (public network integrated-non-public network, PNI-NPN)

PNI-NPN relies on the operator of the PLMN, PNI-NPN being similar to the PLMN, unlike the PLMN in that PNI-NPN is a special slice provided by the PLMN to provide NPN services and/or PNI-NPN is a special data network provided by the PLMN to provide NPN services. That is, not all terminal devices can acquire the NPN service, and if PNI-NPN is a special slice provided by the PLMN to provide the NPN service, only the terminal device authenticated by the slice can acquire the NPN service; if PNI-NPN is that the special data network provided by PLMN provides NPN service, then the terminal device passing authentication can acquire the NPN service in the process of establishing session to the special data network. That is, the PNI-NPN is to perform a service format on the public network service and the private network service by slicing, thereby providing the NPN service for the private network service. The NPN service may include an NPN service or a localization service, for example, the NPN service is a first service or the localization service is a first service.

The above-mentioned SNPN or PNI-NPN may be referred to as a non-public network (NPN), and the nesting network may include an NPN network. The network as opposed to the NPN network may be referred to as a public network, e.g. the public network is a PLMN network.

Localized service (localized service)

The services that the terminal device may acquire at a particular geographic location and/or at a particular time are referred to as localized services. The terminal device may obtain the localized service through NPN or PLMN. That is, the NPN or PLMN may be covered in a specific geographic location and/or for a specific time, and after a time exceeding a specific geographic location or characteristic, the NPN or PLMN is not present, and thus the terminal device is not able to acquire the localization service. The localization service may be provided by NPN or PLMN operator networks or by operators of third parties. Alternatively, the first service may be a localization service. Alternatively, the first service may be a PIN-related service. Alternatively, the localization service may be a PIN related service, for example, a service acquired by the terminal device through the PLMN may be a PIN related service.

Optionally, if the first core network device determines that the first parameter meets the first condition, the first core network device establishes a session for the first service of the terminal device or modifies the session, and so on.

That is, in the first case where the first parameter of the terminal device does not satisfy the first condition in the session establishment or modification for the first service of the terminal device, the first core network device may refuse to establish the session or modify the session for the terminal device, and therefore, the first core network device needs to send a session rejection message to the terminal device, which indicates that the session establishment for the first service of the terminal device is refused.

That is, the first information corresponds to a service identifier of the first service, so that the user plane device can determine the first service identified by the service identifier for stopping the first service according to the first information.

Alternatively, the session management device may send the first information and the service identifier of the first service in one message, or may send the first information and the service identifier of the first service in a different message, which is not limited in the embodiment of the present application.

Optionally, if the foregoing session request message further includes a service identifier of the second service, the session management device may establish a session between the first service and the second service according to the session request message, that is, the service corresponding to the session is the first service and the second service, when the session management device determines that the first parameter of the terminal device does not meet the first condition, the second parameter does not meet the second condition of the second service, the second parameter is a parameter corresponding to second condition information of the second service, and the second condition information indicates that the second condition of the second service is acquired, if the session management device may send the second information to the user plane device, the second information is used to instruct the user plane device to stop sending the second service to the terminal device, where the method further includes: the session management device sends third information to the user plane device, where the third information is used to release the session, in other words, if the session management device determines to stop multiple services of one session, the session management device may send information for stopping the service, or may send information for releasing the session, so that the user plane device may stop sending multiple services to the terminal device, or may release the session.

In addition, if the first parameter meets the first condition and the second parameter does not meet the second condition, the session management device sends second information to the user plane device, and does not send the first information and the third information; if the first parameter does not meet the first condition and the second parameter meets the second condition, the session management device sends the first information to the user plane device and does not send the second information and the third information.

Optionally, in the method 200, the first core network device and the device in communication with the first core network device may be a device in an NPN network, for example, may be a device in an SNPN network, or may be a device corresponding to a slice in a PNI-NPN network.

If the first parameter does not meet the first condition indicated by the first condition information of the first service, the first core network device sends first information, and the first information is used for stopping the terminal device from acquiring the first service. Thereby providing a method of stopping service.

In some embodiments, the service of the terminal device is not stopped if the terminal device is within a defined area providing the service, and the service of the terminal device is stopped if the terminal device is not within the area providing the service. For example, if the terminal device is within the area identified by the tracking area identifier (tracking area identity, TAI), the service of the terminal device is not stopped, and if the terminal device is not within the area identified by the TAI, the service of the terminal device is stopped. However, if the area in which the terminal device uses the service is identified by the TAI, the service of the terminal device cannot be finely managed, and there is a possibility that a loss may occur. For example, a user a of a concert sponsor subscribes to an operator a for a high-definition video playback function that can be obtained at a concert site through a cell phone. That is, only the mobile phone user at the concert site can obtain the high-definition video playback function of the concert site, but the area identified by the TAI may include one or more cells, so that the area identified by the TAI is relatively large, and the mobile phone user except for the concert site in the area identified by the TAI cannot be limited to obtain the high-definition video playback function of the concert site, thereby damaging the benefit of the operator a. Or the operator a may only allow the mobile phone user to obtain the high-definition video playback function of the concert site in a limited time, so that the mobile phone user cannot be limited to obtain the high-definition video playback function of the concert site in time, which may damage the benefit of the operator a. For example, the high-definition video playback function of the concert scene is obtained through a mobile phone and is the first service in the embodiment of the application, so that when the first condition information comprises position information, and the position information is coordinate information or cell information, the service range of the first service can be determined according to a more accurate position, thereby avoiding damaging the benefit of the operator A; when the first condition information includes time information, the time information is time period information or use time length information, a service range of the first service can be determined according to more accurate time, so that benefits of the operator A are prevented from being damaged; when the first condition information is time information and location information, the service range of the first service can be determined according to the dimensions of both time and location, so that the benefit of the operator A is prevented from being damaged.

The UDM sends subscription information to the AMF, which sends subscription information to the UE. Optionally, the AMF sending the subscription information to the UE includes: the AMF transmits subscription information to the UE through a non-access stratum (NAS) message. Optionally, if the UE receives the subscription information, the UE sends a NAS message to the AMF, where the NAS message indicates that the UE successfully receives the subscription information. Optionally, the AMF may send a response message to the UDM, where the response message indicates that the subscription information is successfully sent to the UE if the AMF successfully sends the subscription information, and where the response message indicates that the subscription information is failed to be sent to the UE if the AMF fails to send the subscription information. Optionally, if the AMF receives the NAS message of the UE, the NAS message indicates that the UE successfully receives the subscription information, and the AMF sends a response message to the UDM, where the response message indicates that the subscription information is successfully sent to the UE.

In a third mode, as shown in fig. 5, the UE may send a first subscription request to the AF, where the first subscription request is used to subscribe to the first service, the AF determines subscription information of the first service according to the first subscription request, the AF sends the subscription information of the first service to the UDM through the NEF, the UDM sends the subscription information of the first service to the PCF, and the PCF sends the subscription information to the UE.

Alternatively, the AMF may send a response message to the PCF, where the response message indicates that the urs rule is successfully sent to the UE if the AMF successfully sends the urs rule, and where the response message indicates that the urs rule is failed to send to the UE if the AMF fails to send the urs rule. Optionally, if the AMF receives the NAS message of the UE, the NAS message indicates that the UE successfully receives the urs rule, and the AMF sends a response message to the PCF, where the response message indicates that the urs rule is successfully sent to the UE.

The AF for transmitting subscription information to the UDM in fig. 5 is the same AF as the AF for providing UE subscription data to the UDM in fig. 4, and the UE in fig. 5 is the same UE as the UE in fig. 4. That is, the UE may acquire subscription information of the first service in the public network and request the first service from the private network. And the related information of the first service provided for the public network and the private network is the same AF, for example, the related information of the first service is the first condition information of the first service, so that the information of the first service acquired by the UE and the information of the first service acquired by the network element of the private network can be ensured to be consistent.

Alternatively, the UE may acquire at least one of the service identification of the first service, the DNN of the first service, the slice information of the first service, or the first condition information of the first service in S301 from the private network. The network element of the private network is the network element shown in fig. 4.

Alternatively, the fifth message may include a service identity of the first service, and the UE subscribes to the first service from the AF before the UE sends the fifth message to the RAN, so the UE maintains the service identity of the first service.

Optionally, after the RAN receives the fifth message, the RAN selects an AMF and sends the fifth message to the AMF, the AMF selects an authentication service function (authentication server function, AUSF) and performs a procedure such as authentication, the UE, the AMF, the AUSF and the UDM interactively complete the authentication procedure, and after the authentication is completed, the AMF obtains subscription data of the UE related to the first service from the UDM, for example, the subscription data of the UE related to the first service includes at least one of a service identifier of the first service, a DNN of the first service, slice information of the first service or first condition information of the first service. The AMF sends a NAS message to the UE through the RAN, wherein the NAS message comprises at least one of a service identifier of the first service, DNN of the first service, slice information of the first service or first condition information of the first service. The NAS message may be a response message of the fifth message, which is also called a registration accept message, indicating that the AMF accepts registration of the UE.

S302, the AMF acquires condition information of each service in at least one service.

The following describes two ways in which the AMF obtains the condition information of each of the at least one service.

In one approach, the AMF may subscribe to the UDM for condition information for each of the at least one service, for example by sending a fourth message subscription. When the AF provides condition information of at least one service to the UDM, the UDM may transmit the condition information of the at least one service to the AMF.

Alternatively, the AMF may send a message for subscribing to the localization service to the UDM, where the message includes a TAI corresponding to the AMF, and the UDM sends condition information of each service in at least one service included in the TAI to the AMF. That is, if the AMF manages one or more TAIs, the UDM may send the condition information of each of at least one of the one or more TAIs managed by the AMF to the AMF, that is, it is implied that the condition information of each service includes location information at this time, so that the UDM may send the condition information of the services in the TAIs. Alternatively, if the TAI corresponding to the AMF is not included in the message, the condition information of each service in the at least one service sent by the UDM to the AMF may include time information, that is, if the AMF does not provide the TAI, the UDM may provide the condition information of each service with respect to time to the AMF.

Alternatively, when the third party service provider provides the first service through the private network, the condition information of each of the at least one service may be updated to the UDM of the private network, so that the UDM of the private network may store the condition information of each of the at least one service, and when the AMF subscribes the condition information of each of the at least one service to the UDM, the UDM may send the condition information of each of the at least one service to the AMF. The private network may be the SNPN or PNI-NPN described previously.

Optionally, if the condition information of some services changes, or when some services are newly added, the AF may update the condition information of the changed services with the UDM, for example, the UE subscribes to the first service with the AF, the UDM stores the first condition information of the first service, if the UE subscribes to the second service with the AF, the AF stores the second condition information of the second service in the UDM, and after the UDM receives the second condition information of the newly added second service, the UDM sends the second condition information of the second service to the AMF.

In a second mode, the AMF receives a fifth message sent by the UE, where the fifth message includes a service identifier of the first service. The AMF subscribes to the first condition information of the first service from the UDM according to the service identification of the first service, and the UDM returns the first condition information of the first service to the AMF.

Alternatively, the first service may be a PIN related service. Alternatively, the service identification of the first service may be a PINID. The UDM may store service identification and activation information of each service, and after the UDM acquires the PIN ID of the first service in the fifth message, determine activation information corresponding to the first service according to the PIN ID, and send the activation information to the AMF, so that the AMF may obtain the activation information, where the first condition information may include the activation information.

Optionally, if the AMF receives a registration message of another UE managed by the AMF, and is used for registering a core network providing another service, the AMF may subscribe to condition information of the other service from the UDM, and if the UE subscribes to a second service to the AF, the AMF may include a service identifier of the second service in the fifth message, and the AF stores the second condition information of the second service in the UDM, and the UDM sends the second condition information of the second service to the AMF.

That is, the two ways of acquiring the condition information of each service in the at least one service by the AMF are different in that in the first way, the AMF actively subscribes to the UDM, and the UDM may return to the AMF the condition information of each service stored in the at least one service by the UDM. In the second mode, when the AMF receives the registration message of the UE, the first condition information of the first service may be obtained from the UDM according to the service identifier of the first service in the registration message, and so on, the condition information of each service in the at least one service may be obtained.

Alternatively, in the first and second modes, the AMF may further acquire other relevant information of the first service from the UDM, for example, may be at least one of DNN of the first service, slice information of the first service, service identifier of the first service, and the like, and the manner of acquiring these information is consistent with the manner of acquiring the first condition information of the first service.

It should be noted that the order between S301 and S302 is not limited, and S301 may be performed before or after S302 or simultaneously.

S303, the UE sends a session request message to the AMF, and the AMF receives the session request message sent by the UE, wherein the session request message comprises: the service identification of the first service, the DNN of the first service, at least one of slicing information or session type of the first service.

Alternatively, the session request message may be a session establishment request message for establishing a session, e.g. a modification protocol data unit (protocol data unit, PDU) session, or may be a session modification request message for modifying a session, e.g. a modification PDU session.

Optionally, the session request message may further include a service identifier of the second service, that is, the DNN of the first service may be replaced with the DNNs of the first service and the second service, and slice information of the first service may be replaced with slice information of the first service and slice information of the second service, that is, if the session request message is a session establishment request message, the slice information and the DNN in the session establishment request message are sessions for establishing the first service and the second service, where the first service and the second service correspond to the same session, or the services corresponding to the session are the first service and the second service; if the session request message is a session modification request message, slice information and DNN in the session modification request message are sessions for modifying the first service and the second service, where the first service and the second service correspond to the same session, or the service corresponding to the session is the first service and the second service.

Optionally, if the session request message includes a service identifier of the second service, the session request message may further include second condition information of the second service.

It should be noted that, the session request message may not include the service identifier of the first service, and at this time, the DNN and the slice information correspond to the first service and do not correspond to the second service, that is, when the DNN and the slice information can uniquely identify the first service, the session request message may not carry the service identifier of the first service, and if the DNN and the slice information cannot uniquely identify the first service, the session request message may carry the service identifier of the first service.

Alternatively, if the UE does not acquire the first condition information of the first service in S301, the session request message in S303 may not carry the first condition information of the first service. Or if the UE acquires the first condition information of the first service in S301, the session request message in S303 may or may not carry the first condition information of the first service, that is, if the UE does not acquire the first condition information of the first service, the session request message may or may not carry the first condition information of the first service, and if the UE acquires the first condition information of the first service, the session request message may or may not carry the first condition information of the first service.

Alternatively, S302 may be omitted, and if the session request message includes the first condition information of the first service, the AMF may acquire the first condition information of the first service in the session request message in S303. In other words, the AMF may obtain the first condition information of the first service from other network elements (such as UDM) or may obtain the first condition information of the first service from the UE.

Optionally, the session type in the session request message indicates the session type that the UE desires to establish, and the session type may be determined by the UE, and the UE does not need to acquire the session type from other network elements.

S304, the AMF determines first condition information of the first service from the condition information of at least one service according to the session request message.

Optionally, if the session request message includes a service identifier of the first service, the AMF determines condition information of the first service from condition information of each service in the at least one service according to the service identifier of the first service.

Optionally, if the session request message does not include the service identifier of the first service, and in S302 the AMF may acquire the DNN of the first service, the slice information of the first service and the service identifier of the first service from the UDM, and the DNN is uniquely bound to the slice information and the first service, the AMF determines the service identifier of the first service according to the DNN and the slice information in the session request message in S303, in other words, the AMF acquires the DNN and the slice information of the first service in S302, and if the DNN and the slice information in the session request message sent by the UE in S303 are the DNN and the slice information of the first service in S302, the AMF may determine that the UE needs to establish a session of the first service corresponding to the DNN and the slice information in S302, so the AMF may determine the first condition information of the first service in the condition information of at least one service.

That is, after the session is established or modified after S509b, it may not be determined whether the first parameter of the UE satisfies the first condition. Or, the steps of fig. 8 may also be stored, which indicates that after the session is established or modified, the SMF continues to determine whether the first parameter of the UE satisfies the first condition, and if not, the SMF sends indication information 4 to the UPF, indicating that the UPF stops sending the first service to the UE.
