[0210] In order to make the objects, technical solutions and advantages of the present application clearer, the embodiments of the present application will be described below with reference to the drawings.

[0211] The terms "first" and "second" and the like in the specification of the present application, claims, and drawings are used to distinguish different objects, and are not used to describe a particular order. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device, etc. that includes a series of steps or units is not limited to the listed steps or units, but can optionally include other steps or units not listed or inherent to the process, method, product or device, etc.

[0212] The term "embodiment" mentioned in this document means that the specific features, structures or characteristics described in connection with the embodiment can be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily mean the same embodiment, nor is it an independent or alternative embodiment to other embodiments. Those skilled in the art can understand explicitly and implicitly that in various embodiments of the present application, if there is no special description and logical conflict, the terms and / or descriptions between various embodiments are consistent and can be mutually referred to, and the technical features in different embodiments can be combined to form new embodiments according to their inherent logical relationship.

[0213] It should be understood that in this application, "at least one" means one or more, "multiple" means two or more, "at least two" means two or three and more, and "and / or" is used to describe the association relationship of the associated objects, which means that there can be three relationships, for example, "A and / or B" can mean: only A, only B and A and B exist at the same time, where A and B can be singular or plural. The character " / " generally represents an "or" relationship between the associated objects before and after it. "At least one of the following" or similar expressions means any combination of these items, including any combination of single or multiple items. For example, at least one of a, b or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, c can be single or multiple.

[0214] It should be noted that in this application, "indication" can include direct indication, indirect indication, display indication, and implicit indication. When describing that certain indication information is used to indicate A, it can be understood that the indication information carries A, directly indicates A, or indirectly indicates A.

[0215] In the present application, the information indicated by the indication information is referred to as to-be-indicated information. In the specific implementation process, there are many ways to indicate the to-be-indicated information, for example, but not limited to, the to-be-indicated information can be directly indicated, such as the to-be-indicated information itself or the index of the to-be-indicated information. The to-be-indicated information can also be indirectly indicated by indicating other information, where the other information and the to-be-indicated information have an association relationship. The to-be-indicated information can also be only indicated in part, and the other part of the to-be-indicated information is known or agreed in advance. For example, the indication of specific information can also be achieved by means of the arrangement order of each information agreed in advance (for example, specified by a protocol), thereby reducing the indication overhead to a certain extent. The to-be-indicated information can be sent as a whole, or can be sent separately into multiple sub-information, and the sending period and / or sending occasion of these sub-information can be the same or different. The specific sending method is not limited in the present application. Among them, the sending period and / or sending occasion of these sub-information can be predefined, for example, predefined according to the protocol, or can be configured by the transmitting end device by sending configuration information to the receiving end device.

[0216] It should be noted that in the present application, "sending" can be understood as "output", and "receiving" can be understood as "input". "Sending information to A", where "to A" only indicates the direction of information transmission, and A is the destination, without limiting that "sending information to A" must be direct sending on the air interface. "Sending information to A" includes directly sending information to A, and also includes indirectly sending information to A through a transmitter, so "sending information to A" can also be understood as "outputting information to A". Similarly, "receiving information from A" indicates that the source of the information is A, including directly receiving information from A, and also including indirectly receiving information from A through a receiver, so "receiving information from A" can also be understood as "inputting information from A".

[0217] The method provided by the present application can be applied to various communication systems, for example, it can be an internet of things (IoT) system, a narrow band internet of things (NB-IoT) system, a long term evolution (LTE) system, and also can be a 5th-generation (5G) communication system, and a new communication system (such as 6G) that appears in future communication development.

[0247] It should be understood that the embodiments of the present application are not limited to only be applied in the system architecture shown in FIG. 1. For example, the communication system to which the communication method of the embodiments of the present application can be applied can include more or less network elements or devices. The devices or network elements in FIG. 1 can be hardware, or software functionally divided, or a combination of the above. The devices or network elements in FIG. 1 can communicate through other devices or network elements.

[0248] It should be understood that each of the embodiments shown below can be applied to the communication system shown in FIG. 1, or other forms of communication systems, and the following will not be repeated.

[0249] The present application provides a communication method, which is applied to the field of communication technology, such as communication in the notification push scenario. In order to more clearly describe the scheme of the present application, some knowledge related to notification push will be introduced first.

[0250] The general user registration procedure can be simply described as: the UE sends a registration request to the AMF through the AN, the AMF obtains subscription data from a specific UDM according to the user identifier, and the UDM can obtain the actual subscription data from the UDR after receiving the request. In addition, the AMF can also initiate a user policy control establishment request (UEPolicyControl_Create) and an access management policy control establishment request (AMPolicyControl_Create) to the PCF, respectively, to obtain the UE policy and the access control policy. The PCF returns the access control policy to the AMF in this process, and provides the UE policy to the UE via the AMF.

[0251] The general session establishment procedure can be simply described as: the UE sends a session establishment request to the AMF through the RAN, the AMF selects an SMF to provide services for the session, saves the correspondence between the SMF and the PDU session, and sends the session establishment request to the SMF, the SMF selects a corresponding UPF for the UE and establishes a user plane transmission path, and allocates an IP address for it. In this process, the SMF will also initiate a policy control session establishment request to the PCF, to establish a policy control session between the SMF and the PCF, and in the policy control session establishment process, the SMF will save the correspondence between the policy control session and the PDU session. In addition, the AF can also establish an AF session with the PCF, and the PCF binds the AF session with the policy control session.

[0252] With the rapid development of the fifth generation (5th generation, 5G) communication system, the types of terminal devices are also increasing, in addition to the common mobile phones, tablet computers, terminal devices can also include Internet of Things devices, home gateway devices for home broadband access, etc. The terminal device accesses the network through the access network according to its corresponding subscription information, wherein the subscription information is uniformly managed by the operator and records information including identifying information allowing the terminal device to access the network. A plurality of function network elements in the 5G core network respectively obtain each item of subscription information of the terminal device to provide corresponding function services. For example, the access and mobility management function network element provides the terminal device with function services such as registration, access, and tracking area update procedures by obtaining the access-related subscription of the terminal device, and the session management function network element provides the terminal device with function services of session procedures by obtaining the session-related subscription of the terminal device.

[0257] In the architecture shown in the communication system 200, the PCF performs dynamic notification information decision based on UE granularity events, that is, interactive message bodies such as network service experience notification information, recommended service list, and local service customization information. The PCF issues the above dynamic notification to the UE, and the UE displays. The user of the UE perceives the display content and displays the reminder identifier through the interactive mechanism. Optionally, the user displays the service information after clicking the push notification, and the UE performs the service opening action. Correspondingly, based on the service opening result, the network side enables specific services for the end side and triggers the issuance of specific policy rules.

[0426] It can be understood that the step "the third communication device sends a third request to the fourth communication device" is performed in the case where the fourth communication device is verified to be legitimate.

[0427] It can be understood that the third communication device, after receiving the second information, verifies the legitimacy of the fourth communication device based on the first certificate in the second information, and sends a third request to the fourth communication device to request the first notification information indicated by the first identification information in the second information in the case where the fourth communication device is verified to be legitimate.

[0428] It can be understood that the second information received by the third communication device further includes a first certificate, which is used to verify the legitimacy of the fourth communication device, and the third communication device requests the fourth communication device to obtain the first notification information indicated by the first identification information only in the case where the fourth communication device is verified to be legitimate.

[0429] In a possible embodiment, the communication method can further perform steps including but not limited to the following steps:

[0430] The third communication device sends third information to the first communication device, and correspondingly, the first communication device receives the third information.

[0431] For details, refer to the description of "the third communication device sends third information to the first communication device" above, which will not be repeated here.

[0432] In a possible embodiment, the first notification information includes one or more of the following:

[0433] The service content of the first service, and the second identification information used for subscribing to the first service.

[0434] For details, refer to the description of the content included in the first notification information above, which will not be repeated here.

[0435] In a possible embodiment, the fifth information is further used to indicate that the first notification information is displayed when the display condition is met.

[0436] The display condition is associated with at least one of the following: a network in which the fifth communication apparatus is located, a location in which the fifth communication apparatus is located, a time corresponding to the fifth communication apparatus, and a user response received by the fifth communication apparatus.

[0437] It can be understood that the fifth information is further used to indicate a display condition corresponding to the first notification information, and the display condition is specifically related to one or more of the following: a network in which the fifth communication apparatus is located, a location in which the fifth communication apparatus is located, a time corresponding to the fifth communication apparatus, and a user response received by the fifth communication apparatus.

[0445] In a possible embodiment, the fifth information is further used to indicate that a display area corresponding to the first notification information is associated with a display area corresponding to the operator identifier.

[0446] It can be understood that at present, the terminal side only displays the operator identifier (such as Operator A) in part of the interface, and is usually statically displayed, lacks an interactive mechanism, the notification of the operator cannot be integrated with the operator identifier, and lacks a sense of association with the operator.

[0447] The present application makes the operator identifier into an operating scene, and makes the operator identifier become a service touch point that changes according to the change of the scene, instead of a static symbol. For example, when it is identified that the user is in a high-speed rail and an airport, the user can be reminded that the VIP hall permission can be used in the upper left corner of the terminal device; for example, when it is identified that the user is in a subway, the user can be notified that the exclusive network guarantee is being enjoyed; for example, in a customs scene, the user can be recommended an overseas traffic package, and the like.

[0448] Through the embodiment of the present application, the display of the first notification information can be integrated with the existing operator identifier, and the first notification information can enhance the user's perception of the associated operator and improve the notification efficiency.

[0449] Please refer to FIG. 5, which is a flowchart of another communication method provided by an embodiment of the present application. It can be understood that the steps in the embodiment of the present application can be regarded as a reasonable deformation or supplement of the embodiments in FIG. 3 or FIG. 4; or it can be understood that the communication method in the embodiment of the present application can also be regarded as an independently executable embodiment, and the present application does not limit this. The communication method provided by the embodiment of the present application is applied to the communication technology field, such as the communication in the notification push scene.

[0450] It can be understood that the AM PCF network element involved in the communication method provided by the embodiment of the present application can refer to the first communication device in the communication method shown in FIG. 2 or FIG. 3, the AMF, SM PCF, NWDAF, BOSS and the like involved in the communication method provided by the embodiment of the present application can refer to the second communication device in the communication method shown in FIG. 3 or FIG. 4, the Modem involved in the communication method provided by the embodiment of the present application can refer to the third communication device in the communication method shown in FIG. 3 or FIG. 4, and the AP involved in the communication method provided by the embodiment of the present application can refer to the fifth communication device in the communication method shown in FIG. 3 or FIG. 4, which will not be repeated here.

[0451] The communication method includes but is not limited to the following steps:

[0452] Step 1: the UE performs a registration process (capability information).

[0453] In this step 1, the registration process performed for the UE can be understood as a preceding action of the present communication method.

[0454] The general user registration procedure can be simply described as: the UE sends a registration request to the AMF through the AN, the AMF obtains the subscription data from the specific UDM according to the user identifier, and the UDM can obtain the actual subscription data from the UDR after receiving the request. In addition, the AMF can also initiate a user policy control establishment request (UEPolicyControl_Create) and an access management policy control establishment request (AMPolicyControl_Create) to the PCF, which are used to obtain the UE policy and access control policy respectively. The PCF returns the access control policy to the AMF in this process, and provides the UE policy to the UE via the AMF.

[0455] To simplify the description, this place mainly refers to the interaction actions between the UE, the AMF and the AM PCF. The UE reports the capability information in the registration procedure, indicating that the network side supports the policy notification. Specifically, the capability indication information can be dynamic notification capability indication, or interactive network identifier capability display, and the specific naming is not limited by the embodiments of the present application.

[0456] Optionally, the capability information can be reported to the AM PCF via the AMF. When the AMF receives the capability indication, the AMF can determine whether to further report the capability information to the AM PCF in combination with whether the AMF itself supports forwarding the above-mentioned policy notification information.

[0457] Optionally, when the AMF determines that it also supports forwarding the above-mentioned policy notification information, it can report the capability information of the UE to the AM PCF. It can be understood that different indication information can be used for marking in actual implementation, and the embodiments of the present application do not limit this. It can be understood that the AMF needs to perceive the capability information at this time.

[0458] Optionally, the UE can also directly report its capability information to the AM PCF through the transparent channel between the UE and the AM PCF, and the AMF does not need to perceive the capability information at this time.

[0459] Step 2a: guarantee mechanism takes effect subscription / notification.

[0460] Step 2b: quality difference event subscription / notification.

[0461] Step 2c: location event subscription / notification.

[0462] Step 2d: service promotion / turn-on notification.

[0463] Step 3: policy notification decision.

[0464] In steps 2a to 2d and step 3 described above, the AM PCF actively or passively receives the notification events of the surrounding network elements, and performs policy notification decision based on the event input.

[0465] After receiving the capability information reported by the UE, the AM PCF can initiate a subscription request to the surrounding network elements in combination with local configuration and / or UE subscription information.

[0466] For example, in step 2a above, the SM PCF is subscribed to the guarantee mechanism taking effect event.

[0467] For example, in step 2b above, the NWDAF is subscribed to the user experience report / quality difference analysis report / quality difference event.

[0468] For example, in step 2c above, the AMF is subscribed to the UE location event / UE location change event.

[0469] For example, in step 2d above, the AM PCF can also receive a command from the BOSS, which can carry an indication of issuing a service promotion / activation notification to a target user. Based on this information, the AM PCF can determine the dynamic policy notification content and perform the subsequent process.

[0470] It can be understood that other event information that can be used for policy notification decision can also be subscribed to the above-mentioned network elements or other network elements, and the embodiments of the present application do not limit this.

[0471] It can be understood that when the event occurs, the above-mentioned network elements or other network elements send an event notification message to the AM PCF to trigger the AM PCF to execute the dynamic policy notification decision and generate the aforementioned dynamic policy notification content.

[0472] The dynamic policy notification content can include but is not limited to notification type, notification content, and optional action indication.

[0473] Optionally, the message sent by the above-mentioned network elements or other network elements to the AM PCF can also be the dynamic policy notification content.

[0474] For example, the NWDAF determines the package recommendation content based on user experience analysis and sends the package recommendation information to the AM PCF in the form of dynamic policy notification content. The AM PCF executes the final decision and then issues it to the UE via the AMF.

[0475] It can be understood that in the policy notification decision of step 3 above, the main content involves AM PCF decision input and dynamic policy notification output.

[0476] The AM PCF decision input mainly includes but is not limited to the following content:

[0477] UE capability: capability of receiving dynamic policy notification.

[0478] AMF capability (optional): dynamic policy notification forwarding capability.

[0479] Network side collects input information: usage / account statistics information, user experience evaluation report, network service quality report, location change event and proximity service deployment, time-related policy notification, etc.; or, it can also be understood as time / location / account / service category condition policy.

[0480] Among them, the dynamic policy notification output mainly includes but is not limited to the following contents:

[0481] Notification type: package recommendation, notification display, preferential push.

[0482] Notification content: package description + subscription URL (quality difference event + speed-up package), notification content + subscription URL (remaining amount warning + expansion package), preferential service description + subscription URL (holiday / birthday preferential push description information + service acquisition), information prompt (mobile state prompt: cross-region mobile notification).

[0483] Action instruction (optional): associated public land mobile network name (PLMN Name) instruction, display effective policy (such as: display immediately, display according to location area, display according to time condition, etc.), deletion trigger mechanism (such as: clear after user clicks, clear regularly, etc.).

[0484] Step 4: policy notification issuance.

[0485] In step 4, the AM PCF can optionally issue the policy notification content decided by the AMF. Specifically, it can include but is not limited to the following several issuance methods:

[0486] Method one:

[0487] The CUC message in the NAS message can be extended, and the policy notification content can be carried in the CUC message.

[0488] Method two:

[0489] A first extension message can be added in the NAS message, and the policy notification content can be carried in the first extension message.

[0490] It can be understood that compared with the CUC message carried in the above-mentioned method one, the field extension capability of the first extension message is stronger, and can exceed the field length (65535 bits) limit of the NAS message.

[0491] Method three:

[0492] A second extension message can also be added as a new type of UE Policy, and the policy notification content can be carried in the second extension message.

[0493] Optionally, the second extended message can be the same as the above-mentioned delivery mechanism, and is displayed once by the UE side.

[0494] Optionally, the second extended message can also be multiplexed by the fragmentation / delivery mechanism, and the AM PCF transmits the second extended message to the UE via the AMF, at which time the AMF does not need to be aware of the second extended message.

[0495] It can be understood that the policy notification can include the above-mentioned notification type and notification content information.

[0496] Step 5: policy notification display.

[0497] In step 5, the Modem interacts with the AP, which can include a functional component in the operating system (OS) that interacts with the Modem (hereinafter described as AP) to complete the policy notification display.

[0498] Specifically, it can include: the Modem reports the above-mentioned dynamic policy notification to the AP, the dynamic policy notification includes the notification content and the optional action indication, the AP makes a decision to display the notification content based on the optional action indication in the dynamic policy notification, and supports the pop-up notification window to present the notification content after the user clicks. Alternatively, the Modem can also make a decision to display the notification content based on the optional action indication in the above-mentioned dynamic policy notification, that is, based on the optional action indication, it is judged that the notification content in the dynamic policy notification is reported to the AP under the condition that the corresponding display condition is met, and accordingly, the AP displays the notification content in the dynamic policy notification after receiving the dynamic policy notification.

[0499] Optionally, based on the notification type, it can be displayed in different colors, or displayed in the hyperlink button part (such as: purchase, get, upgrade, subscribe, etc. Text); the notification content can be normally displayed; the action indication can be used to indicate the terminal to execute the display instruction, such as displaying the associated PLMN identifier, displaying only when accessing the current PLMN, the display effective policy is the trigger condition for the terminal to display, and the deletion trigger mechanism is the deletion trigger action of the policy notification content.

[0500] Step 6 (optionally): service opening.

[0501] In step 6, the user initiates the interaction process based on the notification content, and completes the service opening through the BOSS.

[0502] It can be understood that the action is mainly completed on the terminal interface, and the embodiments of the present application do not limit this.

[0503] Step 7: service change notification.

[0504] Step 8: policy update decision / issuance.

[0530] Consistent with steps 7 and 8 in FIG. 5, specific reference can be made to the relevant description of steps 7 and 8 in FIG. 5, which will not be repeated here.

[0531] It can be understood that the current operator provides a notification mode for terminal devices to provide various functional services, which mainly relies on short message function implementation, but the information that can be notified by this mode is relatively limited, it is difficult to simplify the presentation of notification content, and the notification efficiency is low.

[0532] And through the embodiment of the application, the function of pushing specific business services to the terminal side can be realized, and through rendering and display on the terminal side, it is no longer limited to short message push with limited notification capability, which can greatly improve the notification information capability, enrich the notification information content, realize the simplified presentation of notification content, and improve the notification efficiency.

[0533] In addition, for the communication method provided in the application, the application scenarios corresponding to the communication method will be described exemplarily in conjunction with FIGS. 7A to 7C.

[0534] Please refer to FIG. 7A, which is a schematic diagram of a notification interface provided by an embodiment of the application.

[0535] As shown in FIG. 7A, it is an example of AM PCF pushing a package subscription service based on location (such as a concert acceleration package).

[0536] When the user enters a certain concert area range, the AM PCF issues an acceleration package notification based on the location event, and the UE displays a prompt identifier on the left side of the operator identifier after receiving the acceleration package notification.

[0537] When the user clicks the operator identifier, a notification interface is displayed, and the specific acceleration package is displayed on the notification interface.

[0538] When the user clicks the purchase label, the subscription service will be executed.

[0539] After the service subscription is successful, the user can enjoy high-speed Internet service in the specified concert area range.

[0540] It can be understood that, in order to realize the recommendation notification of the above scenario, the regional information needs to be configured on the AM PCF as the package policy recommendation information of the trigger condition (such as, including but not limited to the package name, the package description, and the subscription URL, etc.).

[0541] Optionally, in order to realize the recommendation notification of the above scenario, the communication method provided by the embodiment of the application can perform the following steps including but not limited to:

[0542] Step 1: When the user enters the concert area range, the AMF initiates an N15 request to report a location event to the AM PCF.

[0543] Step 2: The AM PCF dynamically decides the package policy recommendation, and issues the accelerated package information to the AMF through the N15 interface.

[0544] Step 3: After receiving the accelerated package information, the AMF transmits the information to the UE via the NAS message.

[0545] Step 4: After receiving the NAS message, the UE decodes the package information according to the format, and displays the reminder identifier on the left side of the operator identifier.

[0546] Step 5: After the user clicks the operator identifier, a notification interface is displayed, and the specific package name, the package description, and the subscription button information are displayed on the notification interface.

[0547] It can be understood that, in the application scenario, the above "the AMF initiates an N15 request to report a location event to the AM PCF" can correspond to the "the second communication device sends the first information to the first communication device" in the communication method, the above "the accelerated package information" can correspond to the "the second information" in the communication method, and the above "the package name, the package description, and the subscription button information" can correspond to the "the service information corresponding to the first service" in the communication method.

[0548] Through the embodiment of the application, the function service of pushing the specific service to the terminal side can be realized, the rendering display is performed on the terminal side, the notification capability is no longer limited to the short message push, the notification information capability can be greatly improved, the notification information content can be enriched, the notification content can be simplified and presented, and the notification efficiency can be improved.

[0549] Please refer to FIG. 7B, which is a schematic diagram of another notification interface provided by the embodiment of the application.

[0550] As shown in FIG. 7B, it is a notification example of the AM PCF pushing the benefit collection service based on the time (such as, the BOSS delivering the user information).

[0551] On the day before or on the user's birthday, the AM PCF triggers the birthday benefit collection strategy, and the UE receives the birthday benefit collection strategy and displays a reminder identifier on the left side of the operator identifier.

[0552] When the user clicks on the operator identifier, a notification interface is displayed, and the notification interface displays specific birthday benefit information.

[0553] When the user clicks on the collection button, the collection service will be executed.

[0554] After successful collection, the user can enjoy free / preferential benefit services on the birthday.

[0555] It can be understood that, to realize the recommended notification of the above scenario, the dynamic birthday time needs to be configured on the AM PCF as the policy recommendation information of the trigger condition.

[0556] Optionally, to realize the recommended notification of the above scenario, the communication method provided by the embodiment of the application can perform the following steps, but is not limited to:

[0557] Step 1: When the user starts the machine, the AMF initiates an N15 request to the AM PCF.

[0558] Step 2: The AM PCF dynamically activates the birthday benefit collection strategy based on the time condition, and sends the birthday benefit collection strategy to the AMF through the N15 interface.

[0559] Step 3: After receiving the birthday benefit collection strategy, the AMF assembles a NAS message and delivers it to the UE.

[0560] Step 4: After receiving the NAS message, the UE decodes the package information according to the format and displays a reminder identifier on the left side of the operator identifier.

[0561] Step 5: After the user clicks on the operator identifier, a notification interface is displayed, and the notification interface displays specific birthday benefit collection information (such as birthday benefit name, benefit description, and collection button).

[0562] It can be understood that, in the present application scenario, the above-mentioned "AMF initiates an N15 request to the AM PCF" can correspond to the "second communication device sends first information to the first communication device" in the communication method above, the above-mentioned "birthday benefit collection strategy" can correspond to the "second information" in the communication method above, and the above-mentioned "birthday benefit collection information (such as birthday benefit name, benefit description, and collection button)" can correspond to the "service information corresponding to the first service" in the communication method above.

[0563] Through the embodiment of the present application, the function service of pushing specific services to the terminal side can be realized, and the notification information capacity can be greatly improved, the notification information content can be enriched, the notification content can be simplified, and the notification efficiency can be improved by rendering and displaying on the terminal side, instead of being limited to the short message push with limited notification capacity.

[0564] Please refer to FIG. 7C, which is a schematic diagram of another notification interface provided by the embodiment of the present application.

[0565] As shown in FIG. 7C, it is a notification example of the AM PCF pushing the overdue charge reminding service based on the user package usage state delivered by the BOSS.

[0566] When the user charge state changes, the BOSS updates the user attribute information of the AM PCF, the AM PCF triggers the policy calculation to issue the usage state policy, and the UE displays the reminding identifier on the left side of the operator identifier after receiving the usage state policy.

[0567] When the user clicks the operator identifier, the notification interface is displayed, and the specific usage state information is displayed on the notification interface.

[0568] After the user sees the reminder, goes to the hall to recharge, or directly clicks the recharge label to perform the recharge service.

[0569] After the service subscription is successful, the user can normally use the terminal device in a long period of time.

[0570] It can be understood that, to realize the recommended notification of the above scenario, the policy recommendation information with the UE account / usage state as the trigger condition needs to be configured on the AM PCF.

[0571] Optionally, to realize the recommended notification of the above scenario, the communication method provided by the embodiment of the present application can perform the following steps, but is not limited to the following steps:

[0572] Step 1: When the user starts the machine, the AMF initiates N15 request to the AM PCF.

[0573] Step 2: The AM PCF dynamically validates the usage reminding policy based on the usage state of the user, and issues the usage reminding policy to the AMF through the N15 interface.

[0574] Step 3: The AMF receives the usage reminding policy and assembles the NAS message to deliver to the UE.

[0575] Step 4: The UE receives the NAS message, decodes the package information according to the format, and displays the reminding identifier on the left side of the operator identifier.

[0576] Step 5: After the user clicks the operator logo, a notification interface is displayed, which displays specific use state information, such as: xx yuan is owed, please recharge as soon as possible to avoid affecting normal use! (package name, package description).

[0577] In addition, the network side can also send a package guarantee reminder based on the user service guarantee, such as sending corresponding notification information based on the user's service experience evaluation state, or sending corresponding notification content based on the service guarantee taking effect.

[0578] It can be understood that in the application scenario, the above-mentioned "AMF initiates N15 request to AM PCF" can correspond to the "second communication device sends first information to the first communication device" in the communication method, the above-mentioned "use reminder strategy" can correspond to the "second information" in the communication method, and the above-mentioned "use state information, such as: xx yuan is owed, please recharge as soon as possible to avoid affecting normal use! (package name, package description)" can correspond to the "service information corresponding to the first service" in the communication method.

[0579] Through the embodiments of the present application, the function of pushing specific service to the terminal side can be realized, and the rendering display is performed on the terminal side, which is no longer limited to the short message push with limited notification capability, so that the notification information capability can be greatly improved, the notification information content can be enriched, the notification content can be presented simply, and the notification efficiency can be improved.
