[0002] With the development of wireless communication technology, dual-SIM card terminal devices have become a relatively popular terminal device. The so-called dual-SIM card terminal device refers to a terminal device with two independent card slots that can install two subscriber identity module (SIM) cards. Among them, the two SIM cards can belong to the same operator or different operators.

[0131] It is understandable that when the terminal device 40 accesses the first network through the first SIM card 41, it means that the terminal device 40 has not accessed the second network. If the network accessed by the terminal device 40 before accessing the first network is the second network, then when the terminal device 40 accesses the first network, it means that the terminal device 40 temporarily leaves the second network. If the terminal device 40 subsequently switches from the first network to the second network, it means that the terminal device 40 returns to the second network.

[0132] After the terminal device 40 accesses the first network, the first filtering rule can be sent to the first network through the first SIM card, and the first filtering rule is used to limit the paging service. Among them, the limited paging service means that only some services exist among the services for the terminal device, and the first network pages the terminal device. For example, the first filtering rule is to allow only voice services to initiate paging. Therefore, when the terminal device 40 leaves the second network, if there is a service for the terminal device 40, the first network will page the terminal device 40 only if the service is a voice service, that is, when there is a service other than a voice service, the first network will not page the terminal device 40.

[0133] Exemplarily, taking the terminal device 40 as a mobile phone that can be installed with two SIM cards, when the first SIM card 41 in the mobile phone uses the network of China Telecom and the second SIM card 42 uses the network of China Mobile, at the same time, the mobile phone cannot use the first SIM card 41 and the second SIM card 44 to obtain services of the two networks at the same time. When the mobile phone switches from obtaining services of China Telecom to obtaining services of China Mobile, that is, when leaving the network of China Telecom, a first filtering rule can be sent to the network of China Telecom, and the first filtering rule can be used in the network of China Telecom for executing the filtering of paging services (such as the first management network element and the second management network element in the network of China Telecom) to filter the paging service. For example, after the current mobile phone leaves the network of China Telecom, it does not want to receive services other than voice services, that is, paging the mobile phone is only allowed when there is voice service.

[0134] When the terminal device 40 switches from the second network to the first network, the terminal device leaves the second network and returns to the first network. Since the paging service was limited in the first filtering rule when the terminal device left the first network last time, the terminal device is limited to only a specific service of the first network (such as voice service). At this time, after switching back to the first network, the terminal device cannot obtain other services of the network except the voice service. The network element for performing filtering of paging services in the first network (such as the first management network element and the second management network element in the first network) initiates paging to the terminal device 40 based on the previous filtering rules only when there is a voice service for the terminal device 40.

[0135] The embodiment of the present application proposes a method for obtaining services, in which the terminal device can send a first filtering rule to the network, the first filtering rule is used to limit paging services, and can also send a first indication information to the network, which is used to instruct the network to deactivate or update the first filtering rule. On the one hand, it can prevent the terminal device from being unable to obtain other services of the network due to the filtering rules set for the terminal device, thereby ensuring the user's use and improving the stability of the terminal device in obtaining network services. On the other hand, the first filtering rule can also be deactivated or updated according to the instruction of the terminal device, thereby increasing the flexibility of the terminal device in using and adjusting the filtering rules.

[0136] Based on the above content, a method for obtaining services provided by an embodiment of the present application is introduced below. Figure 5 , Figure 5 This is a flow chart of a method for obtaining a service provided by an embodiment of the present application. The method for obtaining a service is implemented by the interaction between a terminal device, a first management network element, and a second management network element. The method for obtaining a service may include the following steps 501 to 506. Among them:

[0137] 501. The terminal device sends a first filtering rule to a first management network element.

[0138] In the embodiment of the present application, the terminal device can switch from the first network to the second network, or from the second network to the first network. The embodiment of the present application takes the switching of the terminal device from the second network to the first network as an example. Figure 5 The first management network element and the second management network element shown are the first management network element and the second management network element in the first network. Among them, the terminal device may be installed with two or more SIM card slots, and one SIM card or multiple SIM cards may be inserted into the two or two SIM cards. The terminal device may also include the functions of one or at least two SIM cards. This application takes the terminal device having dual-card functions or having two SIM cards installed as an example. Among them, the terminal device may obtain services of the first network through the first SIM card and obtain services of the second network through the second SIM card.

[0139] In one implementation, when the terminal device first accesses the first network (for example, when the terminal device is powered on), the terminal device may send an access request to the first management network element in the first network through the first SIM card to request access to the first network. Furthermore, after the terminal device accesses or resides in the first network, it may send an access request to the first management network element in the second network through the second SIM card to request access to the second network when leaving the first network. After the terminal device first accesses the first network and the second network, it may obtain the services of the corresponding networks through the corresponding SIM cards.

[0140] If the terminal device wants to obtain services of the first network after accessing the second network, it can switch from the second network to the first network, that is, the terminal device leaves the second network and returns to the first network, thereby obtaining services of the first network through the first SIM card. Similarly, if the terminal device wants to obtain services of the second network after accessing the first network, it can switch from the first network to the second network, that is, the terminal device leaves the first network and returns to the second network, thereby obtaining services of the first network through the second SIM card.

[0141] In one implementation, when the terminal device leaves the first network, the terminal device can send a first filtering rule to the first management network element of the first network through the first SIM card, and the first filtering rule is used to limit the paging service. Exemplarily, if the first filtering rule is to limit only voice services, then when there is a service for the terminal device, the first management network element and the second management network element in the first network will page the terminal device only when the service is a voice service, and will not page the terminal device for other services except voice services.

[0142] The types of paging services include one or more of voice services, SMS services, and data services. For example, voice services may include services of voice calls initiated by other terminal devices, SMS services may include services of SMS messages sent by other terminal devices, and data services may include services such as games, instant messaging information, and application notifications.

[0143] Furthermore, after the first management network element receives the first filtering rule, it can store the first filtering rule and initiate paging to the terminal device according to the first filtering rule.

[0144] In one implementation manner, the first filtering rule may be carried in a tracking area update (TAU) request, a network attach request, or a service request, which is not limited in the present application.

[0145] 502. The first management network element sends a first filtering rule to the second management network element.

[0146] In one implementation, after the first management network element receives the first filtering rule, the first filtering rule can be sent to the second management network element in the first network (i.e., the network element or device other than the first management network element in the network element for performing filtering paging services). It should be noted that each network element for performing filtering paging services can only implement service filtering for the same terminal device (SIM card) based on the same filtering rule. Therefore, the first management network element notifies the target network device of the first filtering rule, which can determine the successful implementation of service filtering.

[0147] In one implementation, taking the application to 5G as an example, when there is a user plane channel, filtering of the services of the terminal device can be performed on one or more network elements in the user plane channel (RAN, UPF). Preferably, the RAN in the user plane channel filters the services of the terminal device. Optionally, the services of the terminal device can be filtered both on the RAN and on the UPF. Therefore, when the services of the terminal device are filtered only on the RAN, the AMF (first management network element) sends the first filtering rule to the RAN (second management network element); when the services of the terminal device are filtered both on the RAN and on the UPF, the AMF (first management network element) sends the first filtering rule to the RAN and the UPF (second management network element).

[0148] Similarly, when there is a control plane channel, the services of the terminal device can be filtered on one or more network elements in the control plane channel (AMF, SMF, UPF). It is mandatory that the services of the terminal device be filtered on the AMF; optionally, other network elements involved in the control plane (UPF, SMF, RAN) can also filter the services of the terminal device.

[0149] Optionally, when the terminal device is in an idle state (radio resource control (RRC) Idle), the first management network element (AMF) may initiate paging to the terminal device based on the first filtering rule. Optionally, when the terminal device is in an inactive state (RRC Inactive), the second management network element (UPF) may initiate paging to the terminal device based on the first filtering rule.

[0150] 503. The terminal device sends first indication information to the first management network element.

[0151] In one implementation, when the terminal device returns to the first network, the terminal device may send a first indication message to a first management network element in the first network through a first SIM card. The first indication message is used to instruct the first management network element to deactivate or update a first filtering rule, so that the terminal device can obtain at least one service of the first network through the first SIM card. The at least one service in the first network obtained is obtained based on deactivating the above-mentioned first filtering rule, or is obtained by filtering based on the updated first filtering rule. Optionally, the at least one service in the second network may refer to all types of services in the first network.

[0152] In one implementation manner, the first indication information may be carried in a tracking area update (TAU) request, a network attachment request, or a service request, which is not limited in the present application.

[0153] It should be noted that the first management network element is a network element serving the terminal device. It is understandable that the first management network element can also receive the first indication information sent by other terminal devices through the SIM card, that is, the first management network element can also be a network element serving other terminal devices.

[0154] 504. The first management network element deactivates or updates the first filtering rule of the terminal device according to the first indication information.

[0155] In one implementation, the first management network element disables the first filtering rule of the terminal device according to the first indication information. The first indication information can be used to instruct the first management network element to disable (deactivate) the first filtering rule (disable paging filter). After the first filtering rule is disabled, the first management network element may not filter the service for the terminal device, so that if there is a service for the terminal device, the first network pages the terminal device.

[0156] In another implementation, the first indication information may include the second filtering rule, and the first indication information is used to instruct the first management network element in the second network to update the first filtering rule. The first indication information may include the second filtering rule, and the first indication information is used to instruct the first management network element to replace the first filtering rule with the second filtering rule included in the first indication information.

[0157] Exemplarily, the first filtering rule and the second filtering rule may include the types of services that the terminal device is allowed to obtain from the first network. The first filtering rule may be that if there is a service for the terminal device, the first network is allowed to initiate paging to the terminal device in the case of voice services for the terminal device; the second filtering rule may be that if there is a service for the terminal device, the first network is allowed to initiate paging to the terminal device in the case of all services for the terminal device. It should be noted that the first filtering rule and the second filtering rule can be determined according to the actual usage scenario, and this application does not limit this.

[0158] As another example, if the second filtering rule in the first indication information allows the terminal device to obtain all services of the first network, the first management network element can allow all services for the terminal device to pass the filtering when filtering the paging service, and then initiate paging for the services that pass, so that there is no restriction on the terminal device obtaining the services of the second network.

[0159] In one implementation, a plurality of filtering rules are stored in the first management network element, and each filtering rule includes a priority, such as a first filtering rule and a third filtering rule are stored in the first management network element. At this time, the priority of the first filtering rule is higher than that of the third filtering rule, so the first management network element performs filtering based on the first filtering rule. After the first management network element receives the first indication information sent by the terminal device, the first indication information includes priority information, and the priority information indicates that the priority of the third filtering rule is higher than that of the first filtering rule. Therefore, the first management network element performs filtering based on the third filtering rule.

[0160] In one implementation, a plurality of filtering rules are stored in the first management network element, and each filtering rule includes a valid or invalid flag. For example, the first management network element stores a first filtering rule and a third filtering rule. At this time, the first filtering rule is a valid filtering rule, and the third filtering rule is an invalid filtering rule. Therefore, the first management network element performs filtering based on the first filtering rule. After the first management network element receives the first indication information sent by the terminal device, the first indication information includes valid information, and the valid information indicates that the first filtering rule is an invalid filtering rule, and the third filtering rule is a valid filtering rule. Therefore, the first management network element performs filtering based on the third filtering rule.

[0161] Optionally, when the terminal device switches from the first network to the second network, the terminal device leaves the first network, and the first management network element may re-enable the first filtering rule. If the first indication information previously sent by the terminal device to the first network through the first SIM card is used to instruct the first network to disable the first filtering rule (disable paging filter), then when leaving the first network, the indication information may be sent to the first network through the first SIM card, and the first management network element may receive the indication information sent by the terminal device again, and the indication information may be used to instruct the first management network element to re-enable (activate) the first filtering rule (enable paging filter).

[0162] If the first indication information previously sent by the terminal device to the first network through the first SIM card is used to instruct the first network to update the first filtering rule, the indication information sent by the terminal device can be received again, and the indication information includes the first filtering rule. The indication information can instruct the first management network element to replace the currently used filtering rule with the first filtering rule.

[0163] If the priority of the third filtering rule currently stored in the first management network element is higher than the first filtering rule, the first management network element may again receive the indication information sent by the terminal device, and the indication information includes priority information. The priority information may indicate that the priority of the first filtering rule is the highest priority. Then the first management network element performs filtering based on the first filtering rule.

[0164] If the third filtering rule currently stored in the first management network element is a valid filtering rule and the first filtering rule is an invalid filtering rule, the first management network element may again receive the indication information sent by the terminal device, and the indication information includes valid information, which indicates that the first filtering rule is a valid filtering rule and the third filtering rule is an invalid filtering rule, so that the first management network element performs filtering based on the first filtering rule.

[0165] In one implementation, in addition to being used to instruct the first management network element to deactivate or update the first filtering rule of the terminal device (first SIM card), the first indication information can also be used to instruct the first management network element to retain the context information of the terminal device, and the context information includes the first filtering rule. When the first management network element in the first network receives the first indication information, since the first indication information is used to instruct the first management network element to deactivate or update the first filtering rule, and the filtering rule only exists for dual-card terminal devices, the first management network element in the second network can know that the terminal device is a dual-card terminal device, and further, the context information of the terminal device can be retained.

[0166] It should be noted that when the terminal device is a dual-card terminal device, that is, the terminal device is a terminal using two SIM cards, the terminal device can switch from the first network to the second network in a short time through the two SIM cards, or switch from the first network to the second network in a short time through the two SIM cards. Therefore, the first management network element in the first network can retain the context information of the terminal device so as to provide services for the terminal device using the first filtering rule. The context information of the terminal device may refer to the context information related to the multi-card function in the context information of the terminal device.

[0167] In another implementation, the terminal device may send a second indication message to the first management network element, that is, the first management network element may receive the second indication message from the terminal device, and the second indication message is used to instruct the first management network element to retain the context information of the terminal device. The context information of the terminal device refers to the context information of the terminal device related to the multi-card function.

[0168] In one implementation, the first indication information may be used to instruct the first management network element to delete the context information of the terminal device in addition to instructing the terminal device to deactivate or update the first filtering rule. After receiving the first indication information, the first management network element deactivates or updates the first filtering rule according to the first indication information, and deletes the context information of the terminal device. The context information of the terminal device refers to the context information of the terminal device related to the multi-card function. For example, the terminal device may instruct the first management network element to deactivate the first filtering rule and delete the context information of the terminal device.

[0169] 505. The first management network element sends fourth indication information to the second management network element.

[0170] Similarly, each network element for performing filtering of paging services can only implement service filtering for the same terminal device (SIM card) based on the same filtering rules. Therefore, the first management network element informs the second management network element of the fourth indication information, and the fourth indication information is used to instruct the second management network element to deactivate or update the first filtering rule, so that the second management network element deactivates or updates the first filtering rule according to the fourth indication information, which can ensure the successful implementation of service filtering.

[0171] It should be noted that the second management network element is also a network element serving the terminal device. It is understandable that the second management network element can also receive other services of other terminal devices for filtering, that is, the second management network element can also be a network element serving other terminal devices.

[0172] It should be noted that step 505 may be performed before step 504 or simultaneously with step 504, and this application does not limit this.

[0173] 506. The second management network element deactivates or updates the first filtering rule according to the fourth indication information.

[0174] In order to make each network element that performs the filtering paging service based on the same filtering rule for the same terminal (SIM card), the second management network element deactivates or updates the first filtering rule according to the fourth indication information. The manner in which the second management network element deactivates or updates the first filtering rule according to the fourth indication information can refer to the manner in which the first management network element deactivates or updates the first filtering rule according to the first indication information in step 504, which will not be repeated here.

[0175] Optionally, when the terminal device switches from the first network to the second network, the terminal device leaves the first network, and the second management network element may also re-enable the first filtering rule. If the first indication information previously sent by the first management network element to the second management network element is used to indicate the deactivation of the first filtering rule, the indication information may be sent by the first management network element to the second management network element, and the indication information may be used to instruct the second management network element to re-enable (activate) the first filtering rule (enablepaging filter).

[0176] If the fourth indication information previously sent by the first management network element to the second management network element is used to instruct the first network to update the first filtering rule, the indication information sent by the first management network element can be received again, and the indication information includes the first filtering rule. The indication information can instruct the second management network element to replace the currently used filtering rule with the first filtering rule.

[0177] If the second management network element stores the first filtering rule and the third filtering rule, and the priority of the third filtering rule is higher than that of the first filtering rule, the first management network element may again send an indication message to the second management network element, and the indication message includes priority information. The priority information may indicate that the priority of the first filtering rule is the highest priority, and the second management network element then performs filtering based on the first filtering rule.

[0178] If the first filtering rule and the third filtering rule are currently stored in the second management network element, the third filtering rule is a valid filtering rule, and the first filtering rule is an invalid filtering rule, then the first management network element may again send an indication message to the second management network element, and the indication message includes valid information, and the valid information indicates that the first filtering rule is a valid filtering rule and the third filtering rule is an invalid filtering rule, so that the first management network element performs filtering based on the first filtering rule.

[0179] In one implementation, the context information of the terminal device includes a first filtering rule. When the terminal device switches between the first network and the second network in a short period of time through two SIM cards, the second management network element in the first network may also retain the context information of the terminal device, so as to provide services for the terminal device using the first filtering rule. The context information of the terminal device may refer to the context information related to the multi-card function in the context information of the terminal device. Therefore, the first management network element notifies the second management network element to retain the context information of the terminal device.

[0180] In one implementation, in addition to instructing the second management network element to deactivate or update the first filtering rule, the fourth indication information may also notify the second management network element to retain the context information of the terminal device through the fourth indication information. That is, the fourth indication information is also used to instruct the second management network element to retain the context information of the terminal device. The context information of the terminal device may refer to the context information related to the multi-card function in the context information of the terminal device.

[0181] In one implementation, the first management network element may also send fifth indication information to the second management network element, the fifth indication information being used to instruct the second management network element to retain the context information of the terminal device, wherein the context information of the terminal device may refer to the context information related to the multi-card function in the context information of the terminal device.

[0182] In one implementation, after the first management network element receives the first indication information, if the first indication information is also used to instruct the first management network element to delete the context information of the terminal device, the first management network element also needs to notify the second management network element to delete the context information of the terminal device. The instruction to delete the context information can be carried in the fourth indication information. That is, the first management network element sends the fourth indication information to the second management network element. In addition to instructing the second management network element to deactivate or update the first filtering rule, the fourth indication information can also instruct the second management network element to delete the context information of the terminal device. The context information of the terminal device refers to the context information of the terminal device related to the multi-card function.

[0183] For example, please refer to Figure 6 , Figure 6 It is a flow chart of a method for obtaining services in a 5G network architecture provided in an embodiment of the present application. Figure 6 Take 5G as an example to explain, Figure 6 As shown, in the first network, UE, RAN, AMF, SMF, and UPF are included. Taking the first management network element as AMF and the second management network element as RAN, SMF, and UPF as an example, 601, the terminal device (UE) sends the first filtering rule to the first management network element (AMF); 602, after receiving the first filtering rule, the first management network element (AMF) sends the first filtering rule to the second management network element (RAN, SMF, UPF); 603, the terminal device (UE) sends the first indication information to the first management network element (AMF), and the first indication information is used to instruct the first management network element to deactivate or update the first filtering rule; 604, after receiving the first indication information, the first management network element (AMF) sends the fourth indication information to the second management network element (RAN, SMF, UPF), and the fourth indication information is used to instruct the second management network element to deactivate or update the first filtering rule.

[0184] Please also read Figure 7 , Figure 7 is a schematic diagram of a user interface for setting a paging service provided by an embodiment of the present application, such as Figure 7 As shown, the user interface may include a status bar, a SIM card management menu, a scroll bar, and completion and cancel controls. The status bar may include the name of the operator (such as China Mobile), time, WI-FI icon, signal strength, and current remaining power. The status bar may also include a Bluetooth icon, as well as icons of applications when the application has notification information, and so on. The SIM card management menu may include: management of SIM card 1 and SIM card 2, and paging management of SIM card 1. The completion control is used to select the control after the user completes the settings, and the cancel control is used to select the control when the user abandons the settings. It is important to know that Figure 7Only the paging management of SIM card 1 is used as an example. After setting the paging management of SIM card 1, the user can also set the paging management of SIM card 2.

[0185] Specifically, taking the case where two SIM cards are installed in the terminal device, the user interface may display information of the two SIM cards, such as Figure 7 The operator of SIM card 1 is China Mobile, and the number of SIM card 1 is 12345678910; the operator of SIM card 2 is China Telecom, and the number of SIM card 2 is 12345678911; there is a selection box next to the two SIM card information, and the selection box is used for the user to choose whether to use the SIM card. For example, the user can choose not to use a SIM card, or choose to use one SIM card, or choose to use two SIM cards. Figure 7 In the example, a user chooses to use two SIM cards.

[0186] Furthermore, if the user chooses to use SIM card 1, the user can set the paging management of SIM card 1, such as Figure 7 As shown, SIM card 1 may have default filtering rules, such as the first filtering rule, and may also have other default filtering rules. The user may choose to use the first filtering rule for SIM card 1, or may not choose to use the first filtering rule for SIM card 1, that is, deactivate the first filtering rule. The user may also choose to customize the paging service. For example, the user may choose to select the voice service, SMS service, and data service for SIM card 1 separately. Optionally, the voice service, SMS service, and data service may be further set for different applications. Optionally, the user may select all services for SIM card 1 with one click, that is, Figure 7 After the user completes the selection, the user can touch the completion control, and the terminal device can generate a second filtering rule based on the user-defined paging service selected by the user, and then send it to the network corresponding to the SIM card 1 for updating.

[0187] In an embodiment of the present application, in the method for obtaining services, after accessing the network, the terminal device sends filtering rules to the network, thereby limiting the paging service based on the filtering rules, so that the terminal device can receive the paging initiated by the network after filtering based on the first filtering rule, and the terminal device can also send indication information to the network for deactivating or updating the filtering rules, thereby ensuring both user use and terminal device acquisition of services of multiple networks, increasing the flexibility of the terminal device in using and adjusting filtering rules, and improving the stability of the terminal device in acquiring services.

[0188] Based on the above description, please refer to Figure 8 , Figure 8This is another flow chart of a method for obtaining services provided in an embodiment of the present application. The method for obtaining network services can be implemented by the interaction of a terminal device, a first management network element and a second management network element. The method for obtaining services may include the following steps 801-804.

[0189] It should be noted that the same or similar parts between the various embodiments in this application can refer to each other. In the various embodiments in this application, and the various implementation methods / implementation methods / implementation methods in each embodiment, if there is no special explanation and logical conflict, the terms and / or descriptions between different embodiments and the various implementation methods / implementation methods / implementation methods in each embodiment are consistent and can be referenced to each other. The technical features in different embodiments and the various implementation methods / implementation methods / implementation methods in each embodiment can be combined to form new embodiments, implementation methods, implementation methods, or implementation methods according to their inherent logical relationships. The above-described implementation methods of this application do not constitute a limitation on the scope of protection of this application. Among them:

[0190] 801. The terminal device sends third indication information to the first management network element.

[0191] The terminal device can detect the status of the two current SIM cards. If one SIM card is unavailable, the terminal device sends a third indication message to the first management network element of the corresponding network through the available SIM card, and the third indication message is used to instruct the first management network element to delete the context information of the terminal device, and the context information includes the first filtering rule. Optionally, only the context information related to the multi-card function can be deleted, that is, after deleting the context information related to the multi-card function, the context information of the terminal device (such as the context information related to the single card function) still exists in the network corresponding to the available SIM card.

[0192] In a possible implementation manner, the third indication information may be carried in a tracking area update (TAU) request, a network attachment request or a service request, which is not limited in the present application.

[0193] It can be understood that when the terminal device is dual-card, when both cards in the terminal device are available, the terminal device can obtain the services of the first network and the second network based on the first SIM card and the second SIM card used, and the interval between the terminal device accessing the first network and switching to the second network is relatively short. Therefore, for the first network and the second network, the terminal device is in a short-term return network state. Similarly, when the terminal device is single-card, the interval between the terminal device accessing the first network and switching to the second network is relatively long. Therefore, for the first network and the second network, the terminal device is in a long-term return network state.

[0194] Among them, when the terminal device is used for a single card, the user can set a SIM card in the terminal device to be unavailable through a software program. The user can also physically remove a SIM card and only keep one SIM card in the terminal device. That is, the terminal device can detect whether the user makes a card in the terminal device unavailable through a software program, that is, sets it to single card use. The terminal device can also detect that there are two card slots in the current terminal device, each of which can be installed with a SIM card, but one SIM card is removed, that is, it can only detect that one SIM card is retained in the card slot.

[0195] Specifically, the above-mentioned third indication information may include information used to indicate that the terminal device is a terminal device in a long-term return state. Therefore, after receiving the third indication information, the first management network element can delete the context information of the terminal device, and the context information of the terminal device is the context information related to the dual card function in the context information of the terminal device.

[0196] Optionally, the third indication information may also be used to indicate that the terminal device is a single-card terminal device. Being a single-card terminal device means that the terminal device is in a long time return state. Therefore, after receiving the third indication information, the first management network element may delete the context information of the terminal device, where the context information of the terminal device is the context information related to the dual-card function in the context information of the terminal device.

[0197] In one implementation, the terminal device sends seventh indication information to the first management network element of the first network through the second SIM card, and the seventh indication information is used to instruct the first management network element to delete the context information of the terminal device, and the context information includes the first filtering rule. Wherein, the first SIM card is an unavailable card in the terminal device, and the second SIM card is an available card in the terminal device. The available SIM card in the terminal device can send the seventh indication information to the first management network element corresponding to the unavailable SIM card, and the seventh indication information is used to instruct the first management network element to delete the context information of the terminal device, that is, to delete the context information related to the dual-card function in the context information of the terminal device.

[0198] 802. The first management network element deletes the context information according to the third instruction information.

[0199] In one implementation, after receiving the third indication information, the first management network element can know that the terminal device is a terminal device in the long time return state, and can delete the context information of the terminal device based on the indication of the third indication information, the context information is the context information related to the multi-card function in the context information of the terminal device, and the context information includes the first filtering rule. It can be understood that when the terminal device is a single-card terminal device, the above-mentioned first filtering rule is not needed, that is, the context information of the terminal device can be deleted.

[0200] In one implementation, similarly, the first management network element may delete the context information of the terminal device according to the seventh indication information.

[0201] 803. The first management network element sends sixth indication information to the second management network element.

[0202] 804. The second management network element deletes the context information according to the sixth instruction information.

[0203] Among them, each network element for performing filtering of paging services in the network corresponding to the available SIM card in the terminal device implements service filtering for the terminal device based on the filtering rules related to the multi-card function for the available SIM of the terminal device. Therefore, when the terminal device is a terminal device for single-card use, the second management network element in the network corresponding to the available SIM card in the terminal device can delete the context of the terminal device, and the context information of the terminal device includes the filtering rules. Therefore, the first management network element can send the sixth indication information to the second management network element, and the sixth indication information is used to instruct the second management network element to delete the context information of the terminal device. After receiving the sixth indication information, the second management network element deletes the context information of the terminal device according to the instruction of the sixth indication information, wherein what is deleted is the context information related to the multi-card function in the context information of the terminal device.

[0204] It should be noted that step 802 may be performed before step 803 or simultaneously with step 803, and this application does not limit this.

[0205] For example, please refer to Fig. 9 , Fig. 9 This is another flow chart of a method for obtaining services in a 5G network architecture provided in an embodiment of the present application. Fig. 9 Take 5G as an example to explain, Fig. 9 As shown, in the first network, UE, RAN, AMF, SMF, and UPF are included. Taking the first management network element as AMF and the second management network element as RAN, SMF, and UPF as an example 901, the terminal device (UE) sends the third indication information to the first management network element (AMF), and the third indication information is used to instruct the first management network element (AMF) to delete the context information of the terminal device; 902, after receiving the third indication information, the first management network element (AMF) sends the sixth indication information to the second management network element (RAN, SMF, UPF), and the sixth indication information is used to instruct the second management network element (RAN, SMF, UPF) to delete the context information of the terminal device.

[0206] In one implementation, similarly, after the first management network element receives the seventh indication information sent by the terminal device, it can send an eighth indication information to the second management network element. The eighth indication information is used to instruct the second management network element to delete the context information of the terminal device, that is, to delete the context information related to the multi-card function in the context information of the terminal device.

[0207] In an embodiment of the present application, in the method for obtaining services, after accessing the network, the terminal device sends filtering rules to the network, thereby limiting the paging service based on the filtering rules, so that the terminal device can receive the paging initiated by the network after filtering based on the first filtering rule, and the terminal device can also send indication information to the network for deactivating or updating the filtering rules, thereby ensuring both user use and terminal device acquisition of services of multiple networks, increasing the flexibility of the terminal device in using and adjusting filtering rules, and improving the stability of the terminal device in acquiring services.
