[0027] This disclosure provides an information processing method, a communication device, a communication system, and a storage medium.

[0028] In a first aspect, embodiments of this disclosure propose an information processing method executed by a first network function, comprising: acquiring first information, wherein the first information is used to indicate conditions for canceling services provided by a terminal; and, upon detecting that the conditions are triggered, performing a first operation, wherein the first operation includes one of the following: sending second information to a second network function, wherein the second information is used to request cancellation of services provided by the terminal, wherein the first network function is a third network function; and canceling services provided by the terminal, wherein the first network function is the second network function.

[0029] In the above embodiments, the first network function can perform the first operation of canceling the service provided by the terminal, so that the network function in the core network can cancel the service provided by the terminal. This can reduce the occurrence of unnecessary failures when unavailable services are discovered and / or invoked by the network function in the core network.

[0030] In conjunction with some embodiments of the first aspect, in some embodiments, obtaining the first information includes at least one of the following: obtaining the first information based on configuration information; obtaining the first information from a terminal.

[0031] The above embodiments provide multiple ways to obtain the conditions for the services provided by the deregistration terminal, adapting to more application scenarios.

[0032] In conjunction with some embodiments of the first aspect, in some embodiments, the conditions include at least one of the following: a first condition, wherein the first condition is one of the following: the terminal is deregistered from the network, the terminal is deregistered from the network and a first timer expires; a second condition, wherein the second condition is one of the following: the terminal is determined to be unreachable, the terminal is determined to be unreachable and a second timer expires; a third condition, wherein the third condition is one of the following: the session for the services provided by the terminal is set to packet-switched (PS) data closed or the session is deactivated or the session is released; the session is set to PS data closed or the session is deactivated or the session is released, and a third timer expires; a fourth condition, wherein the fourth condition is one of the following: the terminal is set to PS data closed; the terminal is set to PS data closed, and a fourth timer expires.

[0033] In the above embodiments, when the first network function is a third network function (i.e., a network function that does not manage the services provided by the terminal), the conditions may include one or more of the first, second, third, and fourth conditions, thus adapting to more application scenarios. For example, when the condition is the first condition, since the terminal has been deregistered from the network, the services provided by the terminal are unavailable. Deregistering the services provided by the terminal in this way can reduce unnecessary failures caused by unavailable services still being discovered and / or invoked by network functions in the core network. Similarly, when the condition is the second condition, since the terminal cannot reach the network, for example, the terminal cannot communicate with the network (core network equipment), the services provided by the terminal are unavailable. Deregistering the services provided by the terminal in this way can reduce unnecessary failures caused by unavailable services still being discovered and / or invoked by network functions in the core network. For example, when the third condition is met, the PS data of the terminal's session is closed, the session is deactivated, or the session is released. Or, when the fourth condition is met, the PS or data of the terminal is closed. Thus, the session or data channel between the terminal and the peer is unavailable, and the services provided by the terminal are unavailable. In this case, canceling the services provided by the terminal can reduce unnecessary failures caused by unavailable services still being discovered and / or invoked by network functions in the core network.

[0034] In conjunction with some embodiments of the first aspect, in some embodiments, the first network function is a third network function, and the detection of a condition being triggered includes at least one of the following: determining that a first condition has been triggered based on the terminal initiating terminal deregistration; determining that the terminal has deregistered from the network based on the third network function; determining that the first condition has been triggered based on the terminal initiating terminal deregistration and a first timer expiring; determining that the first condition has been triggered based on the third network function determining that the terminal has deregistered from the network and a first timer expiring; determining that the first condition has been triggered based on the third network function determining that the terminal is unreachable; determining that a second condition has been triggered based on the third network function determining that the terminal is unreachable and... The second timer times out, confirming that the second condition has been triggered; based on the third network function, it is determined that the session used by the terminal to provide services is set to PS data off, the session is deactivated, or the session is released, confirming that the third condition has been triggered; based on the third network function, it is determined that the session used by the terminal to provide services is set to PS data off, the session is deactivated, or the session is released, and the third timer times out, confirming that the third condition has been triggered; based on the third network function, it is determined that the terminal is set to PS data off, confirming that the fourth condition has been triggered; based on the third network function, it is determined that the terminal is set to PS data off and the fourth timer times out, confirming that the fourth condition has been triggered.

[0035] In the above embodiments, the third network function can determine that the detected condition has been triggered in a variety of ways, and can be applied to more application scenarios.

[0037] In the above embodiments, the third network function can also notify the second network function of the information that the condition has been triggered through the request sent by the second network function. This can enable the second network function to detect that the condition has been triggered while also reducing the burden on the second network function.

[0041] In the above embodiments, when the first network function is the second network function (i.e., the network function that manages the services provided by the terminal), the conditions may include one or more of the first, second, third, fourth, and fifth conditions, thus adapting to more application scenarios. For example, when the condition is the fifth condition, the services provided by the terminal have not been called by the network function for a period of time, and the probability of the services provided by the terminal being called is not very high; thus, the services provided by the terminal are deregistered, thereby reducing the burden on the second network function.

[0042] In conjunction with some embodiments of the first aspect, in some embodiments, detecting that a condition has been triggered includes at least one of the following: determining that a fifth condition has been triggered based on a fifth timer timeout and the service provided by the terminal not being invoked by any network function; or determining that a condition has been triggered based on fifth information obtained from a third network function.

[0043] In the above embodiments, the second network function can determine that the detected condition has been triggered in a variety of ways, and can be applied to more application scenarios.

[0102] In some embodiments, an increasing number of application services that require data processing within the communication system are supported, such as on terminals, in the core network, and in some network functions of the access network, and support is not limited to supporting at least one of the following services:

[0103] Sensing services. Sensing is the use of radio frequency signals to acquire information about the characteristics of the environment and / or objects in the environment (e.g., shape, size, orientation, speed, position, distance, or relative motion between objects).

[0104] Integrated sensing and communication (ISAC) services. ISAC involves the simultaneous use of radio frequency signals for sensing and communication. This integration of sensing and communication can improve spectrum efficiency, reduce latency, and / or enhance the reliability of various applications. ISAC is particularly suitable for at least one of the following: mobile operators, UE vendors, automotive vendors, and users, as it can significantly enhance the overall user experience, improve network efficiency, and / or generate new business opportunities.

[0105] Artificial Intelligence (AI) / Machine Learning (ML) services. The convergence of communication networks and AI technologies is leveraging AI / ML to achieve intelligence in the core network and air interface through closed-loop processes such as data collection, ML model training, analysis and inference, and consumer data analysis.

[0106] Ranging / Sidelink Positioning service. Ranging refers to determining at least one of the following via the PC5 interface: the distance between two or more UEs, the orientation of one UE (i.e., the target UE) relative to another UE (i.e., the reference UE), and / or relative positioning. Sidelink positioning uses PC5 to locate the UE.

[0107] For example, the reference UE is a UE that determines a reference plane and reference orientation in ranging and / or lateral walkway-based positioning. The target UE is a UE whose distance, orientation, and / or position are measured compared to the reference plane, reference orientation, and / or position of the reference UE in ranging and / or lateral walkway-based positioning.

[0108] For example, ranging / sidewalking link positioning may include the following steps: measuring the absolute position between two UEs, or between one UE and multiple UEs, or between one or more positioned UEs; calculating the result (e.g., at the location server UE, or at the LMF, or at both); and making the ranging / sidewalking link positioning result available to the UE or the server (or a third-party application server).

[0109] Enhanced Location Service (eLCS) / Location Services. UE positioning can be supported by RAT-related positioning methods, which rely on, for example, RAT measurements obtained by the target UE and / or measurements of RAT signals transmitted by the target UE obtained by the access network. UE positioning can also be supported by RAT-independent positioning methods, which may rely on non-RAT measurements and / or other information obtained by the UE.

[0110] For example, the entire procedure of eLCS / location includes: measuring the absolute position between the UE and the base station; calculating the result (e.g., on the UE or in the LMF); and making it available to the UE or a third-party server (or a third-party application server).

[0111] In order to support applications that require data processing in communication systems, based on the development of terminals and their increasingly powerful capabilities, such as handheld computers, it is feasible to apply service-based architecture (SBA) on terminals to support applications that require data processing in communication systems.

[0112] In some embodiments, the terminal can be a UE, and the UE can be a terminal.

[0113] Figure 2A is an interactive schematic diagram illustrating an information processing method according to an embodiment of the present disclosure. As shown in Figure 2A, this embodiment of the present disclosure relates to an information processing method used in an information processing system 100, the method comprising:

[0114] Step S2101: The first network function acquires the first information.

[0115] In some embodiments, the first network function is a second network function or a third network function. Optionally, the second network function can be one of the following: NRF, URF, UDM, UDR, and any NF used to manage services provided by the terminal. Optionally, the third network function can be one of the following: AMF, SMF, UDM, UDR, and any NF used to detect when a condition of the management terminal is triggered but the management terminal does not provide services.

[0116] In some embodiments, the terminal sends first information to a first network function.

[0117] In some embodiments, the first network function receives first information sent by the terminal.

[0118] Optionally, during previous interactions between the terminal and the first network function (before step S2101), for example, during the process of the terminal instructing or triggering the registration or update of services provided by the UE, or during any mobility management process between the UE and the first network function, the terminal sends first information to the first network function; thus, the first network function can obtain the first information from the terminal.

[0119] In some embodiments, the operator equipment sends configuration information to the first network function.

[0120] In some embodiments, the first network function receives configuration information sent by the operator equipment and determines first information based on the configuration information. Thus, the first network function can determine the first information based on the configuration information. Optionally, the configuration information includes at least conditions for instructing the cancellation of services provided by the terminal.

[0121] Alternatively, the operator equipment can be an operation and maintenance (OAM) system.

[0122] Optionally, the first network function receives configuration information sent by the operator equipment, which can be sent offline or online.

[0123] Optionally, before the first network function receives the configuration information sent by the operator equipment, it may further include: sending a sixth message to the operator equipment, the sixth message being used to request the conditions for canceling the terminal from providing services.

[0124] In some embodiments, the first information is used to indicate the conditions for canceling the services provided by the terminal. Here, the conditions can be replaced by events.

[0125] Optionally, the first information is used to indicate an event that cancels the service provided by the terminal, or the first information is used to indicate the conditions or event for canceling the terminal service. Here, the terminal service can be: a service provided by the terminal, or a registered service provided by the terminal. Cancellation can refer to unregistering or deleting; for example, service cancellation can be service unregistration or service deletion, etc.

[0126] Optionally, the services provided by the service or terminal may include: supporting at least one of the following for a single business: data detection, data collection, data processing, data distribution, data management, and business management; or supporting at least one of the following for multiple businesses: data detection, data collection, data processing, data distribution, data management, and business management.

[0127] Optionally, the service can be any service in the previous embodiments, or the service can be at least one of the following, including but not limited to: sensing service, positioning service, ranging / SL positioning service, AI service, ML service, AI / ML service, ISAC service, and environmental IoT service, etc.

[0128] Optionally, the conditions include at least one of the following: the first condition, the second condition, the third condition, the fourth condition, and the fifth condition.

[0129] Optionally, the name of the condition is not limited, and it may be, for example, an event, a terminal service deregistration condition, or a terminal service deregistration event.

[0130] For example, when the first network function is the third network function, the conditions include at least one of the following: a first condition, a second condition, a third condition, and a fourth condition.

[0131] For example, when the first network function is the second network function, the conditions include at least one of the following: a first condition, a second condition, a third condition, a fourth condition, and a fifth condition.

[0132] For example, the first condition is one of the following: the terminal logs off from the network, the terminal logs off from the network and the first timer times out.

[0133] For example, the second condition is one of the following: the terminal is determined to be unreachable, the terminal is determined to be unreachable and the second timer times out.

[0134] For example, the third condition is one of the following: the session for the service provided by the terminal is set to PS data closed, the session is deactivated, or the session is released; the session is set to PS data closed, the session is deactivated, or the session is released, and the third timer times out. Optionally, the third condition is for a session or a Protocol Data Unit (PDU) session.

[0135] For example, the fourth condition is one of the following: the terminal is set to PS data off; the terminal is set to PS data off, and the fourth timer times out. Optionally, the fourth condition is specific to the terminal.

[0136] For example, the fifth condition is: the service provided by the terminal is not invoked by any network function within the time period of the fifth timer.

[0137] For example, the term "session" can be replaced with any term used to describe the signaling control processing of the channel or data connection for managing data transmission and the corresponding data transmission channel or data connection. This data transmission channel or data connection can be used for data transmission between a data terminal and a data network (e.g., a server in the data network). Here, management includes, but is not limited to, establishing, modifying, and / or deleting; the data transmission channel can be a user plane channel or a data plane channel; the data connection can refer to a logical connection or a non-logical connection. Deactivating the session means that the data transmission channel or data connection corresponding to the session is partially or completely released, but the corresponding signaling control processing information is still retained in each associated node (e.g., the terminal and associated network functions). Releasing the session means that both the signaling control processing information corresponding to the session and the corresponding data transmission channel or data connection are deleted.

[0138] For example, the name of the session is not limited, and it may be a PDU session or a Public Data Network (PDN) connection, or any newly defined channel used to describe the management of data transmission, or the name of the signaling control processing of the data connection and the corresponding data transmission channel or data connection, etc.

[0139] Here, timer timeout refers to the expiration of a timer's set time or the reaching of its end time. For example, a first timer timeout means the expiration of the first timer's set time or the reaching of its end time. Similarly, second, third, and fourth timer timeouts, as well as the fifth or sixth timer timeouts described below, can all be understood in a similar way to the first timer timeout. Terminal unreachable can mean that the terminal cannot connect to the network; for example, terminal unreachable can mean that the terminal cannot connect to core network equipment or access network equipment. PS data shutdown means preventing network connection transmission of data other than data required for service exemption; for example, PS data shutdown means turning off data traffic in the terminal.

[0140] In some embodiments, the name of the first information is not limited, and it may be, for example, condition or event indication information or terminal service deregistration condition or event indication information.

[0141] In step S2102, the first network function determination condition is triggered.

[0142] In some embodiments, a condition being triggered can mean that the condition occurs, the condition is met, or an event corresponding to the condition occurs.

[0143] Optionally, the first network function detects that a condition has been triggered or that a condition has occurred.

[0144] Optionally, the first network function determines that the conditions for terminal service deregistration are currently met.

[0145] Optionally, the first network function detects that the condition is triggered or that the condition is met.

[0146] In some embodiments, the first network function is a third network function, and the conditions for determining the third network function are triggered.

[0147] Optionally, the third network function determines that the first condition has been triggered based on the terminal-initiated terminal deregistration.

[0148] Optionally, the third network function determines that the first condition has been triggered based on the terminal's initiation of terminal deregistration and the expiration of the first timer.

[0149] For example, terminal-initiated terminal deregistration; for instance, the terminal sends a terminal deregistration request to a third network function, and the third network function can determine that a first condition has been triggered or occurred based on the terminal sending the terminal deregistration request.

[0150] For example, based on the above embodiments, if a first timer is also set in the third network function, after the third network function terminal is logged out, the first timer is started to time out, and when the first timer times out, it is determined that the first condition has been triggered or occurred.

[0151] Optionally, the third network function determines that the terminal has logged out of the network based on the third network function, and determines that the first condition has been triggered.

[0152] Optionally, the third network function determines that the terminal has logged out of the network and the first timer has expired, or the third network function determines that the terminal has logged out of the network and then starts the first timer to expire and the first timer expires, thus determining that the first condition has been triggered.

[0153] For example, the third network function determines from the UE information in the third network function that the terminal has deregistered from the network, or obtains UE information from other NFs in the core network, and determines based on the UE information that the terminal has deregistered from the network or cannot connect to the terminal, and determines that the first condition has been triggered or occurred.

[0154] For example, based on the above embodiments, if a first timer is also set in the third network function, the third network function determines that the first timer has been triggered or occurred when the first timer expires after determining that the terminal has logged out of the network, or when the third network function starts the first timer to expire after determining that the terminal has logged out of the network.

[0155] For example, the third network function can also obtain UE information that the terminal has been deregistered from the UDM or UDR; or the UDM or UDR can send the terminal deregistration information to the third network function (e.g., AMF or SMF) so that the third network function (e.g., AMF or SMF) knows that the terminal has been deregistered from the network.

[0156] Optionally, after UDM or UDR obtains the UE information of the terminal being deregistered as a third network function, it can also perform the following step S2103A (i.e., send the second information to the NRF or URF in the second network function).

[0157] Optionally, based on the third network function, it is determined that the terminal is unreachable, and it is determined that the second condition has been triggered.

[0158] Optionally, based on the third network function, if it is determined that the terminal is unreachable and the second timer has expired, it is determined that the second condition has been triggered.

[0159] Optionally, based on the third network function, it is determined that the session used to provide services to the terminal is set to PS data closed, the session is deactivated, or the session is released, and the third timer expires, thus determining that the third condition has been triggered.

[0160] Optionally, the third network function determines, based on the third network function, that the session used to provide services to the terminal is set to PS data closed, or the session is deactivated, or the session is released, and determines that a third condition has been triggered.

[0161] Optionally, based on the third network function, it is determined that the terminal is set to PS data off and the fourth timer has expired, thus determining that the fourth condition has been triggered.

[0162] For example, for a session (e.g., a PDU session), if the session PS data providing the service is closed, or the session is deactivated or released, it is determined that the session is unavailable, i.e., the data channel connecting the terminal and the peer (e.g., a specified data network) is unavailable. Therefore, it is determined that a third condition has been triggered. Because the data channel is unavailable at this time, the service provided by the corresponding terminal cannot be used; thus, by determining that the third condition has been triggered, the service provided by the terminal can be cancelled.

[0163] Optionally, the third network function determines that the terminal is set to PS data off based on the third network function, and determines that the fourth condition has been triggered.

[0164] For example, for a terminal, if PS data is turned off, it is determined that the terminal cannot transmit data, and the corresponding services provided by the terminal will be unusable. Thus, by determining that a third condition has been triggered, the services provided by the terminal can be cancelled.

[0165] In some alternative embodiments, the method further includes: a third network function determining that the terminal is unreachable.

[0166] Optionally, the third network function determines that the terminal is unreachable if the sixth timer for determining the terminal's reachability expires based on the third network function.

[0167] For example, the sixth timer is used to detect the reachability of the terminal (e.g., to detect whether the terminal is reachable or unreachable); if the terminal is unreachable (or has not yet changed from unreachable to reachable) when the sixth timer expires, the third network function determines that the terminal is unreachable. The sixth timer may expire before the second timer starts; the terminal's unreachability can be determined based on the expiration of the sixth timer.

[0168] Optionally, the third network function determines that the terminal is unreachable based on the third information sent from the access network device by the third network function, wherein the third information is used to indicate that the terminal is unreachable.

[0169] For example, when an access network device determines that a terminal is unreachable, it sends third information to a third network function, which indicates that the terminal is unreachable; the third network function can determine that the terminal is unreachable based on the received third information.

[0170] In some embodiments, the first network function is a second network function, and the conditions for determining the second network function are triggered.

[0171] Optionally, the second network function determines that the fifth condition has been triggered based on the timeout of the fifth timer and the fact that the service provided by the terminal has not been invoked by any network function. For example, the second network function determines that the fifth condition has been triggered when it determines that the service provided by the terminal has not been invoked by any network function within a predetermined time period.

[0172] For example, the second network function may set a fifth timer. For instance, the fifth timer may be set and started after the services provided by the terminal are registered with the second network function, or the fifth timer may be set and started based on the current time. The second network function determines that if the services provided by the terminal are not called by any network function when the fifth timer expires, it determines that the fifth condition has been triggered or occurred.

[0173] Optionally, the second network function determines that the condition is triggered based on the fifth information obtained from the third network function, and the fifth information is used to determine that the condition is triggered.

[0174] For example, the fifth information is used to indicate that the third network function has detected that a condition (such as one or more of the first to fourth conditions described above) has been triggered.

[0175] For example, the fifth information is used to indicate various events or information that can trigger the condition; the second network function, upon receiving the fifth information, can determine whether the condition is triggered based on the fifth information and the condition indicated in the first information.

[0176] In some alternative embodiments, the second network function receives fifth information sent by the third network function, wherein the fifth information is used to determine that a condition has been triggered. Here, the second network function may determine that the condition has been triggered based on the fifth information obtained from the third network function; and the third network function will perform the operation of determining whether the condition has been triggered.

[0177] Optionally, the third network function sends the fifth message to the second network function.

[0178] Optionally, the name of the fifth piece of information is not limited; it may be, for example, a condition-triggered notification or message, or a terminal service deregistration condition notification.

[0179] In some optional embodiments, before the second network function receives the fifth information sent by the third network function, the method further includes: the second network function sending a fourth information to the third network function, wherein the fourth information is used for the fifth information triggered by the request or subscription condition.

[0180] Optionally, the third network function receives the fourth information sent by the second network function.

[0181] Optionally, the name of the fourth piece of information is not limited, and it may be, for example, a condition-triggered subscription request or a terminal service deregistration conditional subscription request.

[0182] For example, if the fourth information is used to request or subscribe to information that triggers the condition, then the fifth information is or indicates information that triggers the condition; or, if the fourth information is used to request or subscribe to information that does not trigger the condition, then the fifth information is or indicates information that does not trigger the condition.

[0183] In step S2103, the first network function performs the first operation. Optionally, step S2103 includes step S2103A or step S2103B.

[0184] Optionally, the first network function performs a first operation upon detecting that a condition (one or more of the aforementioned first, second, third, fourth, and fifth conditions) is triggered or occurs. Here, the first operation includes one of the following: sending second information to the second network function; or deregistering the services provided by the terminal.

[0185] Optionally, the services provided by the deregistration terminal may include: one or more services provided by the deregistration terminal, or all services provided by the deregistration terminal.

[0186] In step S2103A, the first network function sends second information to the second network function. Optionally, the first network function is a third network function.

[0187] In some embodiments, the first network function is a third network function; the third network function sends second information to the second information when it detects that a condition has been triggered or occurred.

[0188] In some embodiments, the second network function receives second information sent by the third network function, the second information being sent by the third network function after detecting that a condition has been triggered or occurred.

[0189] Optionally, the second information is used to request the cancellation of services provided by the terminal. For example, the second information is used to request the cancellation of registered services provided by the terminal.

[0190] Optionally, the second information is used to deregister services provided by the second network function deregister terminal. For example, the second information is used to deregister registered services provided by the second network function deregister terminal.

[0191] Optionally, the second information may include at least one of the following: a first identifier and a second identifier; the first identifier is used to indicate a terminal; the second identifier is used to indicate a second network function.

[0192] Optionally, the name of the second information is not limited, and it may be, for example, a service deregistration request, a service deregistration request message, a service cancellation registration request, or a service cancellation registration request message.

[0193] In some embodiments, the third network function sends the second information to the second network function through the fourth network function.

[0194] Optionally, the third network function sends the second information to the fourth network function, and the fourth network function sends the second information to the second network function.

[0195] Optionally, the second network function receives second information sent by the fourth network function, the second information being obtained by the fourth network function from the third network function.

[0196] Optionally, the second information sent by the third network function to the fourth network function is the same as the second information sent by the fourth network function to the second network function, or the second information sent by the third network function to the fourth network function differs from the second information sent by the fourth network function to the second function in terms of content, parameter format, etc., as long as both satisfy the same requested purpose.

[0197] Step S2103B: The first network function cancels the services provided by the terminal. Optionally, the first network function is a second network function.

[0198] In some embodiments, the first network function is a second network function, which deregisters the services provided by the terminal upon detecting that a condition has been triggered or occurred. For example, the second network function deregisters all services registered by the terminal.

[0199] Step S2104: The second network function cancels the services provided by the terminal.

[0200] In some embodiments, the second network function receives second information sent by the third network function and cancels the services provided by the terminal. For example, if the second information indicates cancellation of one or more services, the second network function cancels the one or more services indicated by the second information; or, if the second information indicates cancellation of services, the second network function cancels all services registered by the terminal.

[0239] In some embodiments, the above methods may include the methods described in the above-described information processing system side, first network function, second network function and / or third network function side, etc., which will not be repeated here.

[0240] This disclosure relates to an information processing method, which can be a method for an authorized NF to deregister services provided by a service-based UE in a network, thereby reducing the probability of unnecessary failures when unavailable UE services are discovered and / or consumed by network functions within the core network. Here, deregistration can be replaced by cancellation or deletion; consumption can be replaced by invocation.

[0241] In some embodiments, the method may include at least one of the following:

[0242] The authorized NF determines the trigger for UE service deregistration (i.e. UE service cancellation) in the network, wherein the authorized NF determines the trigger for UE service deregistration in the network by at least one of the following: the authorized NF configures the conditions for UE service cancellation in the network through configuration or dynamic indication from the UE; the authorized NF triggers the UE service cancellation conditions in the network, or the authorized NF receives an event or information corresponding to triggering the UE service cancellation conditions in the network;

[0243] The NF is authorized to perform UE service deregistration procedures in the network. Here, UE service refers to the services provided or supported by the UE.

[0244] In some embodiments, the communication system may include core network equipment, access network equipment, and UE; for some SBA UEs, some functions of the mobile station (e.g., UE) are provided through services, such as the function of providing at least one or more (application) services: sensing services, positioning services, ranging / side-link positioning services, AI services, ML services, ISAC services, and environmental IoT services.

[0245] In some embodiments, at least one of the following services may be provided for one or more of the above-described (application) services: data detection, data collection, data processing, data distribution, data management, and service management. Based on service management of services provided by UEs based on services in the network, network functions within the network can discover UE services and consume (e.g., invoke) relevant UE services.

[0246] In some embodiments, the UE can be a terminal, or the terminal can be a UE.

[0247] Example 1: UE service deregistration initiated by an NF that does not manage UE services.

[0248] In this embodiment, the authorizing NF initiates UE service deregistration on behalf of the UE. Therefore, by deregistering, the UE service cannot be discovered and / or consumed (e.g., invoked) by NFs in the core network, reducing the likelihood of unsuccessful UE service invocations when the network attempts to invoke an unavailable UE service. The authorizing NF is the NF that triggers UE service deregistration on behalf of the UE; it can be, for example, an AMF, SMF, UDM, or UDR. Here, "representative" can be replaced by a proxy or substitute.

[0249] In some embodiments, as shown in FIG4A, the information processing method may include the following steps:

[0250] Step S4100: The authorized NF is configured with information for UE service deregistration.

[0251] Optionally, the UE may include at least one UE, such as UE1 or UE2; in Figure 4A, the UE may be UE1. The authorizing NF can be used to trigger UE service deregistration on behalf of the UE; the authorizing NF may be an AMF, SMF, UDM, or UDR, etc. The authorizing NF may be a third network function as described in previous embodiments.

[0252] Optionally, the information used for UE service deregistration may be one or more of the following conditions for UE service deregistration:

[0253] The first condition is one of the following: the UE deregisters from the network, or the UE deregisters from the network and the first timer times out;

[0254] The second condition is one of the following: the UE is determined to be unreachable, or the UE is determined to be unreachable and the second timer times out;

[0255] The third condition is one of the following: the session for the service provided by the UE is set to PS data off, the session is deactivated, or the session is released; the session is set to PS data off, the session is deactivated, or the session is released, and the third timer times out.

[0256] The fourth condition is one of the following: the UE is set to PS data off; the UE is set to PS data off and the fourth timer times out.

[0257] Here, the condition for UE service deregistration can be replaced with the event for UE service deregistration; the PDU session can be replaced with the session.

[0258] Here, when a UE deregisters from the network, UE service deregistration can be triggered by the authorized NF; and optionally, the authorized NF can gracefully deregister the UE service after a configured timer expires (e.g., the first timer expires). Alternatively, when a UE is determined to be unreachable from the network, UE service deregistration can be triggered by the authorized NF; and optionally, the authorized NF can gracefully deregister the UE service after a configured timer expires (e.g., the second timer expires). Alternatively, when a session used for UE service is configured to PS data closed, or the session is deactivated or dereleased, UE service deregistration can be triggered by the authorized NF. Graceful deregistration of the UE service here can either mean not deregistering immediately, or it can provide a buffer time for ongoing services to complete their current processing.

[0259] Optionally, the configuration of information for UE service deregistration can be performed in different ways, for example, in the following ways:

[0260] Configured via operator equipment (e.g., OAM);

[0261] Instructions can be made by the UE. For example, during previous interactions between the UE and network devices, such as during any process used by the UE to instruct or trigger service registration or service updates, or during any mobility management process between the UE and an authorized NF (e.g., AMF or SMF), via dynamic instructions from the UE.

[0262] Step S4101: The authorized NF detects that the conditions for UE service deregistration have occurred or been triggered.

[0263] Optionally, the authorized NF detects that the conditions or events configured (or pre-configured) for UE service deregistration in step S4100 have occurred; for example, it may include one or more of the following:

[0264] The system determines whether the UE has deregistered from the network. For example, the UE may initiate deregistration, and the AMF (Application Function Foundation) may confirm the UE's deregistration; or the AMF may confirm implicit deregistration; or the UDM (User Device Manager) or UDR (User Receiver Manager) may confirm the UE's deregistration and send the confirmation to the AMF, which then confirms the UE's deregistration. Here, the AMF is a third-party network function. Another example is that the UDM or UDR may confirm the UE's deregistration; here, the UDM or UDR is a third-party network function.

[0265] The system determines that the UE has become unreachable from the network. For example, if the AMF determines that a timer for mobility reachability has expired and optionally notifies the SMF, UDM, or UDR that the UE has become unreachable from the network, then the AMF, SMF, UDM, or UDR determines that the UE is unreachable; or if the access network device determines that the UE is unreachable and notifies the AMF, SMF, UDM, or UDR of the UE's unreachability, then the AMF, SMF, UDM, or UDR determines that the UE is unreachable.

[0266] SMF determines whether the PDU session used for UE service is set to PS data off, or the PDU session is deactivated, or the PDU session is released. Here, SMF stands for Third Network Function.

[0267] AMF determines whether the UE is set to PS data off or whether PS data off is activated on the UE. Here, AMF stands for Third Network Function.

[0268] Step S4102: Authorize the NF to process the UE service deregistration request on behalf of the UE.

[0269] Optionally, the authorized NF determines the request to perform UE service deregistration on behalf of the UE based on the UE service deregistration conditions / events configured in step S4100 and the UE service deregistration conditions / events detected in step S4101.

[0270] Optionally, authorizing the NF to perform UE service deregistration procedures on behalf of the UE may include at least one of the following:

[0271] If the UE service has already been registered in the network, a request to deregister (or unregister) the UE service can be constructed (by implementing the service deregistration call request via HTTP).

[0272] The target NF to be requested can be determined. The target NF can be an SCP, an NRF, or any new NF used for UE service management. Information of the target NF (e.g., the identifier of the target NF) can be recorded from previous UE service registration or UE service update processes. This information of the target NF can be used to authorize the NF to determine the target NF requested for the UE service deregistration request.

[0273] If an SCP is involved, a request for UE service deregistration is sent to the SCP as in step S4103A below. If no SCP is involved (e.g., UE service management is provided directly by the NRF), a request for UE service deregistration is sent to the NRF as in step S4103B below. Alternatively, if UE service management is provided by a new NF, a request for UE service deregistration is sent to the new NF.

[0274] Alternatively, the target NF can be the second network function in the previous embodiments.

[0275] In step S4103A, the AMF sends a request for UE service deregistration to the NRF or URF via the SCP.

[0276] Optionally, if the AMF determines in step S4102 that an SCP is involved, it sends a request for UE service deregistration to the SCP. This request for UE service deregistration can reuse an extended NF management NF deregistration service (e.g., Nnrf_NFManagement_NFUpdate service) to support services provided for UE service deregistration; the services requested for deregistration may include services provided by the UE corresponding to the terminal's identifier (UE ID). Alternatively, the services requested for deregistration may be new services, such as services provided by the UE with the UE ID included in the management terminal service deregistration request (e.g., Nnrf_SvcManagement_UEUpdate Request). The user UE service deregistration request may include the UE file containing the UE ID and the services provided by the UE.

[0277] Optionally, the SCP will send the received request for UE service deregistration to the NRF, URF, or a new NF for UE service management.

[0278] In step S4104A, the NRF or URF sends a response for UE service deregistration to the AMF via SCP.

[0279] Optionally, the NRF, URF, or a new NF for UE service management stores a UE file containing UE services, which indicates that the relevant services for the UE are unavailable and confirms acceptance of UE service deregistration to the AMF via SCP.

[0280] In step S4103B, the AMF sends a request to the NRF or URF for UE service deregistration.

[0281] Optionally, the AMF sends a request for UE service deregistration to the NRF, URF, or a new NF for UE service management. The request for UE service deregistration in step S4103B is similar to the request for UE service deregistration in step S4103A, except that step S4103B involves direct communication, while step S4103A involves indirect communication.

[0282] In step S4104B, the NRF or URF sends a response to the AMF for UE service deregistration.

[0283] Optionally, the NRF, URF, or a new NF for UE service management stores a UE file containing UE services, indicating that the relevant services for the UE are unavailable, and confirms acceptance of UE service deregistration to the AMF. For example, the NRF or the new NF for UE service management sends a response for UE service deregistration to the AMF, indicating acceptance of UE service deregistration.

[0284] Step S4105, AMF performs the processing of the UE service deregistration response.

[0285] Optionally, the AMF processes the UE service deregistration response; for example, the AMF records the UE service registration status based on the UE service deregistration response or notifies the UE of service deregistration when the UE can connect to the network.

[0286] Example 2: The NF that manages the UE service initiates the UE service deregistration.

[0287] In this embodiment, the authorizing NF initiates UE service deregistration on behalf of the UE to the network. Therefore, by deregistering, the UE service cannot be discovered and / or consumed (e.g., invoked) by NFs in the core network, reducing the likelihood of unsuccessful UE service invocation when the network attempts to invoke it. The authorizing NF is the NF that manages the UE service, such as an NRF, URF, UDM, UDR, or any NF used for managing UE services. Here, "representing" can be replaced by "proxy" or "substitute".

[0288] In some embodiments, as shown in FIG4B, the information processing method may include the following steps:

[0289] Step S4200: The authorized NF is configured with information for UE service deregistration.

[0290] Optionally, the UE may include at least one UE, such as UE1 or UE2; in Figure 4B, the UE may be UE1. The authorizing NF can be used to trigger UE service deregistration on behalf of the UE; the authorizing NF may be an NRF, URF, UDM, UDR, or any NF used to manage UE services. The authorizing NF may be a second network function as described in previous embodiments.

[0291] Optionally, the information used for UE service deregistration may be one or more of the following conditions for UE service deregistration:

[0292] The first condition is one of the following: the UE deregisters from the network, or the UE deregisters from the network and the first timer times out;

[0293] The second condition is one of the following: the UE is determined to be unreachable, or the UE is determined to be unreachable and the second timer times out;

[0294] The third condition is one of the following: the protocol data unit session for the service provided by the UE is set to packet-switched PS data closed or the session is deactivated or released; the session is set to PS data closed or the session is deactivated or released, and the third timer times out.

[0295] The fourth condition is one of the following: the UE is set to PS data off; the UE is set to PS data off and the fourth timer expires;

[0296] The fifth condition is that the services provided by the UE are not invoked by any network function within the time interval of the fifth timer.

[0297] Here, the condition for UE service deregistration can be replaced with the event of UE service deregistration; PDU session can be replaced with session.

[0298] Here, when a UE deregisters from the network, UE service deregistration can be triggered by an authorized NF; and optionally, the authorized NF can gracefully deregister the UE service after a configured timer expires (e.g., the first timer expires). Alternatively, when a UE is determined to be unreachable from the network, UE service deregistration can be triggered by an authorized NF; and optionally, the authorized NF can gracefully deregister the UE service after a configured timer expires (e.g., the second timer expires). Alternatively, when a session used for UE service is configured to PS data closed, or the session is deactivated or dereleased, UE service deregistration can be triggered by an authorized NF. Alternatively, when the UE service is not invoked by any NF within the timeout period of a configured timer (e.g., the fifth timer), UE service registration can be triggered via an authorized NF. Graceful deregistration of the UE service here can either prevent immediate deregistration or provide a buffer time for ongoing services to complete their current processing.

[0299] Optionally, the configuration of information for UE service deregistration can be performed in different ways, for example, in the following ways:

[0300] Configured via operator equipment (e.g., OAM);

[0301] Instructions from the UE. For example, during previous interactions between the UE and network devices, such as during any process used to instruct the UE or trigger service registration or service updates, via dynamic instructions from the UE.

[0302] Step S4201A1: The AMF / SMF / UDM / UDR detects an event that triggers the UE service deregistration condition or the UE service deregistration condition occurs. Here, AMF / SMF / UDM / UDR refers to AMF, SMF, UDM, or UDR.

[0303] Optionally, step S4201A1 is similar to step S4101; embodiments of step S4201A1 can be found in embodiments of step S4101. AMF, SMF, UDM, or UDR can be the third network function in the previous embodiments. Step S4201A1 can also be performed after step S4201A2.

[0304] Step S4201A2: Authorize the NF to subscribe to the AMF / SMF / UDM / UDR for events that trigger UE service deregistration conditions or events that trigger UE service deregistration conditions.

[0305] Optionally, the authorized NF sends a UE service deregistration event subscription request to the AMF, SMF, UDM, or UDR. This UE service deregistration event subscription request is used to request subscription to the event triggered by the conditions for UE service deregistration. Here, the UE service deregistration event subscription can be the fourth information in the previous embodiments.

[0306] Step S4201A3: AMF / SMF / UDM / UDR notifies the authorizing NF subscription service cancellation event.

[0307] Optionally, the AMF, SMF, UDM, or UDR sends a UE service deregistration event notification to the authorized NF. This notification indicates the event that triggers the conditions for UE service deregistration. Here, the UE service deregistration event notification can be the fifth piece of information as described in the previous embodiments.

[0308] Step S4201B: The authorized NF detects that the conditions for UE service deregistration have occurred.

[0309] Optionally, the authorized NF detects that the conditions for UE service deregistration have occurred, including one or more of the following:

[0310] The authorized NF detects that the inactivity period of the timer has expired (e.g., the fifth timer has expired) and the service provided by the UE has not been invoked by any NF;

[0311] The authorized NF receives UE service deregistration event notifications sent by AMF, SMF, UDM, or UDR.

[0312] Step S4202: Authorize the NF to process the UE service deregistration request on behalf of the UE.

[0313] Optionally, the authorizing NF determines a request to perform UE service deregistration on behalf of the UE based on the UE service deregistration conditions / events configured as in step S4200 and the UE service deregistration conditions / events detected as in step S4201B. The authorizing NF implicitly performs the UE service deregistration process on behalf of the UE.

[0314] In a Service-Based Architecture (SBA), interaction between network functions can be achieved by invoking services, rather than sending request and response messages. In non-SBA architectures, this is achieved by sending corresponding messages. For example, in SBA, sending a request to a specified interface corresponds to invoking the service provided by the corresponding network function, and the corresponding response corresponds to the output of the service call. Of course, for other requests, it is also possible to invoke the corresponding service implementation, and the response to that request corresponds to the output of the corresponding service call; there are no specific limitations on the requests and / or responses.

[0315] In some embodiments, if the access network device (e.g., (R)AN mentioned above) supports the Service-Based Interface (SBI) interface with the AMF, the above scheme can also be applied. Similarly, sending a request is achieved by calling the corresponding service, and the corresponding response is the result of the service call.

[0316] In the above embodiments, considering the emergence of more and more application services and the development of mobile terminals, a service-based UE architecture is developed. Services provided by service-based UEs are managed in the network, and unavailable UE services should be deregistered to reduce the probability of unnecessary failures when unavailable UE services are discovered and / or consumed (e.g., invoked) by network functions in the core network. It can also provide lower complexity and better scalability to support new application services that require data processing within the telecommunications system.

[0317] In this embodiment of the disclosure, some or all of the steps and their optional implementations can be arbitrarily combined with some or all of the steps in other embodiments, or arbitrarily combined with the optional implementations in other embodiments.

[0318] This disclosure also provides an apparatus for implementing any of the above methods. For example, an apparatus is provided that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Alternatively, another apparatus is provided that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0319] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an Application-Specific Integrated Circuit (ASIC), and the functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), which can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0320] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a Digital Signal Processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an Application-Specific Integrated Circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. In addition, it can also be hardware circuits designed for artificial intelligence, which can be understood as ASICs, such as Neural Network Processing Units (NPUs), Tensor Processing Units (TPUs), and Deep Learning Processing Units (DPUs).

[0326] As shown in Figure 6A, the communication device 6100 includes one or more processors 6101.
