Please refer to fig. 2 and fig. 3 together, wherein fig. 2 is a schematic diagram of a network architecture of 5G, and fig. 3 is a diagram of a network architecture of 4G. As shown in fig. 2, the network architecture includes a terminal equipment (UE), a mobility management function (AMF) network element, a Radio Access Network (RAN) device, a Session Management Function (SMF) network element, and a User Plane Function (UPF) network element.

The UE is connected with the RAN through a Radio Resource Control (RRC) protocol, the UE is connected with the AMF through an N1 interface, and the UE and the AMF communicate through an N1 non-access stratum (NAS) message; the RAN is connected with the AMF through an N2 interface, and the RAN and the AMF are in message communication through N2; the AMF is connected with the SMF through an N11 interface, and the AMF and the SMF are in message communication through N11; the RAN is connected with the UPF through an N3 interface, and the RAN and the UPF are in message communication through an N3; the UPF is connected to the SMF via an N4 interface, and the UPF and the SMF communicate via N4 messages.

For example, in 5G, the first management network element 11 shown in fig. 1 may be the AMF shown in fig. 2, and the second management network element 12 shown in fig. 1 may be one or more of the RAN, SMF, and UPF shown in fig. 2.

As shown in fig. 3, the network architecture includes a terminal device, a RAN, a mobility management node function (MME), a Serving Gateway (SGW), and a network gateway (PGW). Wherein the RAN is operable to a device in wireless communication with the terminal device; the MME is used for carrying out mobility management on the terminal equipment and is responsible for managing the mobility context, the session context and the security information of the terminal equipment; the SGW mainly provides the functions of the user plane; the PGW is responsible for functions such as charging, lawful interception, etc.

The UE is connected with the RAN through an RRC protocol; the RAN is connected with the MME through an S3 interface, and the RAN and the MME are in message communication through an S3 interface; the RAN is connected with the SGW through an S1 interface, and the RAN and the SGW are in message communication through S1; the MME is connected with the SGW through an S11 interface, and the MME and the SGW are in message communication through S11; the SGW is connected with the PGW through an S5/S8 interface, and the SGW and the PGW are in message communication through S5/S8.

It should be noted that, when the method is applied to different communication systems, names of the first management network elements may be different, and this is not limited in this embodiment of the application.

Based on the above description of the system and network architecture for acquiring services, please refer to fig. 4 together, and fig. 4 is a schematic structural diagram of a terminal device according to an embodiment of the present application. As shown in fig. 4, one or at least two card slots into which SIM cards can be inserted may be installed in the terminal device 40, and the terminal device 40 may also be a terminal device including at least one SIM card. Two SIM cards installed in the terminal device 40: the first SIM card 41 and the second SIM card 42 are different in networks used for accessing, that is, services of different networks can be obtained through different SIM cards. Illustratively, the terminal device 40 via the first SIM card 41 may send an access request to a first management network element 43 in a first network to request access to the first network, and the terminal device 40 via the second SIM card 42 may send an access request to a first management network element 44 in a second network to request access to the second network. It should be noted that the terminal device 40 cannot access two or more networks at a time, and only can access one network.

It is understood that, in the case that the terminal device 40 accesses the first network through the first SIM card 41, it means that the terminal device 40 does not access the second network. If the network to which the terminal device 40 accesses before accessing the first network is the second network, the terminal device 40 indicates that the terminal device 40 temporarily leaves (leave) the second network when accessing the first network. If the terminal device 40 subsequently switches from the first network to the second network, it indicates that the terminal device 40 returns (return) to the second network.

After the terminal device 40 accesses the first network, a first filtering rule for defining paging traffic may be sent to the first network through the first SIM card. The paging service is defined as that only partial service exists in the service aiming at the terminal equipment, and the first network pages the terminal equipment. For example, the first filtering rule is to allow only voice (voice) traffic to initiate paging. Therefore, in the case of the leave second network of the terminal device 40, if there is a service for the terminal device 40, the first network pages the terminal device 40 only if the service is a voice service, that is, if there is a service other than a voice service, the first network does not page the terminal device 40.

For example, taking the terminal device 40 as a mobile phone capable of installing two SIM cards as an example, when the first SIM card 41 in the mobile phone uses a network of china telecommunication and the second SIM card 42 uses a 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 the service of acquiring the china telecommunication to the service of acquiring the china mobile, that is, leaves (leave) the network of the china telecommunication, the first filtering rule may be sent to the network of the china telecommunication, and the first filtering rule may be used for filtering the paging service by a network element (e.g., a first management network element and a second management network element in the network of the china telecommunication) in the network of the china telecommunication, which is used for performing the filtering of the paging service. For example, after the current handset leaves the network of chinese telecommunications, it does not want to receive other services than voice services, i.e. it is only allowed to page the handset when there is voice service.

When the terminal device 40 is switched from the second network to the first network, the terminal device leave second network and the terminal device 40return the first network, because the paging service is defined in the first filtering rule when the last leave first network is used, that is, it is defined that the terminal device can only obtain one specific service (such as voice service) of the first network. At this time, after the terminal device is switched back to the first network, it cannot acquire other services of the network except the voice service. The network element in the first network (e.g., the first management network element, the second management network element in the first network) for performing filtering paging traffic initiates paging to the terminal device 40 only when there is voice traffic for the terminal device 40 based on the previous filtering rule.

In the method for acquiring the service, a terminal device may send a first filtering rule to a network, where the first filtering rule is used to limit a paging service, and may also send first indication information to the network, where the first indication information is used to indicate that the network is deactivated or update the first filtering rule. On one hand, the problem that the terminal equipment cannot acquire other services of the network due to the filtering rule set for the terminal equipment can be avoided, so that the use of a user is ensured, and the stability of the terminal equipment for acquiring the network services is improved. On the other hand, the first filtering rule can be deactivated or updated according to the indication of the terminal equipment, so that the flexibility of using and adjusting the filtering rule by the terminal equipment is increased.

Based on the above, a method for acquiring a service provided in the embodiment of the present application is described below. Referring to fig. 5, fig. 5 is a flowchart of a method for acquiring a service according to an embodiment of the present application, where the method for acquiring a service is implemented by a terminal device, a first management network element, and a second management network element in an interactive manner, and the method for acquiring a service may include the following steps 501 to 506. Wherein:

501. the terminal equipment sends the first filtering rule to the first management network element.

In this embodiment of the present application, a terminal device may switch from a first network to a second network, or may switch from the second network to the first network, and this embodiment of the present application takes as an example that the terminal device switches from the second network to the first network, that is, a first management network element and a second management network element shown in fig. 5 are a first management network element and a second management network element in the first network. The terminal equipment can be provided with two or more than two SIM card slots, one SIM card can be inserted into the two or more than two SIM cards, a plurality of SIM cards can also be inserted into the two or more than two SIM cards, and the terminal equipment can also have the functions of one or at least two SIM cards. The terminal equipment can acquire the service of the first network through the first SIM card and acquire the service of the second network through the second SIM card.

In an implementation manner, in a case that the terminal device accesses the first network for the first time (for example, in a case that the terminal device is powered on), the terminal device may send an access request to a first management network element in the first network through the first SIM card to request to access the first network. Furthermore, after accessing or residing in the first network, the terminal device may send an access request to the first management network element in the second network through the second SIM card under the condition of the leave first network, so as to request to access the second network. After the terminal equipment is firstly accessed to the first network and the second network, the service of the corresponding network can be obtained through the corresponding SIM card.

If the terminal device wants to acquire the service of the first network after accessing the second network, the terminal device may switch from the second network to the first network, that is, the terminal device leave second network, return the first network, so as to acquire the service of the first network through the first SIM card. Similarly, after the terminal device accesses the first network, it may switch from the first network to the second network, that is, the terminal device leave first network, return the second network, and thereby obtain the service of the first network through the second SIM card.

In one implementation, in the case of a leave first network, the terminal device may send, through the first SIM card, a first filtering rule to a first management network element of the first network, where the first filtering rule is used to limit paging traffic. For example, if the first filtering rule is to limit that only voice traffic is allowed, when there is traffic for the terminal device, the first management network element and the second management network element in the first network page the terminal device only if the traffic is voice traffic, and do not page the terminal device for other traffic except for voice traffic.

The type of the paging service includes one or more of a voice service, a short message service and a data service. For example, the voice service may include a service of a voice call initiated by other terminal devices, the short message service may include a service of a short message sent by other terminal devices, and the data service may include services of games, instant messaging information, notification of application programs, and the like.

Further, after the first management network element receives the first filtering rule, the first filtering rule may be stored, and a paging may be initiated to the terminal device according to the first filtering rule.

In an implementation manner, the first filtering rule may be carried in a Tracking Area Update (TAU) request, a network registration (attach) request, or a service request (service request), which is not limited in this application.

502. The first management network element sends the first filtering rule to the second management network element.

In one implementation, after receiving the first filtering rule, the first management network element may send the first filtering rule to a second management network element in the first network (i.e., a network element or a device other than the first management network element in a network element for performing filtering paging service). It should be noted that each network element for performing filtering paging service can only implement service filtering on the same terminal device (SIM card) based on the same filtering rule for the same terminal device (SIM card). Therefore, the first management network element informs the target network device of the first filtering rule, and can determine the successful operation of the service filtering.

In one implementation, for example, the application to 5G is explained, and when a user plane channel exists, filtering the service of the terminal device may be performed on one or more network elements in the user plane channel (RAN, UPF). Preferably, the RAN in the user plane tunnel filters the traffic of the terminal device. Optionally, the service of the terminal device may be filtered on the RAN, and the service of the terminal device may also be filtered on the UPF. Therefore, when the traffic of the terminal device is 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 traffic of the terminal device is filtered both on the RAN and on the UPF, the AMF (first management network element) sends a first filtering rule to the RAN and the UPF (second management network element).

Similarly, when a control plane tunnel exists, the traffic of the terminal device may be filtered on one or more network elements in the control plane tunnel (AMF, SMF, UPF). Optionally, the AMF filters the service of the terminal device; optionally, other network elements (UPF, SMF, RAN) involved in the control plane may also filter the traffic of the terminal device.

Optionally, in a case that 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, in a case that 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.

503. And the terminal equipment sends the first indication information to the first management network element.

In one implementation, in the case that the terminal device returns to the first network, the terminal device may send the first indication information to a first management network element in the first network through the first SIM card. The first indication information is used for indicating the first management network element to deactivate or update the first filtering rule, so that the terminal device can acquire at least one service of the first network through the first SIM card. The obtained at least one service in the first network is obtained by deactivating the first filtering rule or 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.

In an implementation manner, the first indication information may be carried in a Tracking Area Update (TAU) request, an attach (attach) request, or a service request (service request), which is not limited in this application.

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

504. And the first management network element deactivates or updates the first filtering rule of the terminal equipment according to the first indication information.

In one implementation, the first management network element deactivates the first filtering rule of the terminal device according to the first indication information. The first indication information may be used to indicate that the first management network element deactivates (deactivates) the first filtering rule (disabling filtering filter), and after the first filtering rule is deactivated, the first management network element may not filter the service for the terminal device, so that if the service for the terminal device exists, the first network pages the terminal device.

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

For example, the first filtering rule and the second filtering rule may include a type of service that allows the terminal device to acquire 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 under the condition of a voice service for the terminal device; the second filtering rule may be that, if there is traffic for the terminal device, the first network is allowed to initiate paging to the terminal device in case of all traffic for the terminal device. It should be noted that the first filtering rule and the second filtering rule may be determined according to an actual usage scenario, which is not limited in this application.

For another example, if the second filtering rule in the first indication information is that all services allowing the terminal device to acquire the service of the first network are allowed, the first management network element may filter all services for the terminal device when filtering the paging service, and then initiate paging for the passed services, so that there is no limitation on the terminal device acquiring the service of the second network.

In one implementation, the first management element stores a plurality of filtering rules, each filtering rule including a priority, for example, the first management element stores a first filtering rule and a third filtering rule. At this time, the first filtering rule has a higher priority than the third filtering rule, so the first management element performs filtering based on the first filtering rule. After receiving the first indication information sent by the terminal device, the first indication information includes priority information indicating that the priority of the third filtering rule is higher than that of the first filtering rule. Thus, the first managing network element performs filtering based on the third filtering rule.

In one implementation, the first management element stores a plurality of filtering rules, each filtering rule includes a valid or invalid identifier, and if the first management element stores a first filtering rule and a third filtering rule, the first filtering rule is a valid filtering rule, and the third filtering rule is an invalid filtering rule. After receiving the first indication information sent by the terminal device, the first indication information includes valid information, where the valid information indicates that the first filtering rule is an invalid filtering rule, and the third filtering rule is a valid filtering rule. Thus, the first managing network element performs filtering based on the third filtering rule.

Optionally, in a case that the terminal device is switched from the first network to the second network, the first management network element of the terminal device leave first network 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 indicate that the first network disables the first filtering rule (disabling filtering filter), when the terminal device leaves the first network, the first management network element may send the indication information 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, where the indication information may be used to indicate that the first management network element re-enables (activates) the first filtering rule (enabling filtering filter).

If the first indication information sent by the terminal device to the first network through the first SIM card is used to indicate the first network to update the first filtering rule, the indication information sent by the terminal device may be received again, where the indication information includes the first filtering rule, and the indication information may indicate that the first management network element replaces the currently used filtering rule with the first filtering rule.

If the priority of the third filtering rule stored in the current first management network element is higher than the first filtering rule, the first management network element may receive the indication information sent by the terminal device again, where the indication information includes priority information, and the priority information may indicate that the priority of the first filtering rule is the highest priority, and then the first management network element performs filtering based on the first filtering rule.

If the third filtering rule stored in the current 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 receive the indication information sent by the terminal device again, where the indication information includes valid information indicating 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.

In an implementation manner, in addition to the first indication information used for indicating that the first management network element deactivates or updates the first filtering rule of the terminal device (first SIM card), the first indication information may also be used for indicating that the first management network element retains context information of the terminal device, where the context information includes the first filtering rule. When the first management network element in the first network receives the first indication information, because the first indication information is used to indicate that the first management network element deactivates or updates the first filtering rule, and the filtering rule exists only for the dual-card terminal device, the first management network element in the second network may know that the terminal device is the dual-card terminal device, and further, may retain the context information of the terminal device.

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 may be switched from the first network to the second network in a short period through the two SIM cards, or switched from the first network to the second network in a short period (short time) through the two SIM cards. Accordingly, the first management network element in the first network may retain context information of the terminal device in order to provide the service to the terminal device using the first filtering rule. The context information of the terminal device may refer to context information related to a multi-card function in the context information of the terminal device.

In another implementation manner, the terminal device may send second indication information to the first management network element, that is, the first management network element may receive the second indication information from the terminal device, where the second indication information 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.

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. And 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 equipment. 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 managing network element to deactivate the first filtering rule and delete the context information of the terminal device.

505. And the first management network element sends the fourth indication information to the second management network element.

Similarly, each network element for executing filtering paging service can only implement service filtering for the same terminal device (SIM card) based on the same filtering rule for the same terminal device (SIM card). Therefore, the first management network element informs the second management network element of fourth indication information, where the fourth indication information is used to indicate the second management network element to deactivate or update the first filtering rule, so that the second management network element deactivates or update the first filtering rule according to the fourth indication information, which can ensure successful service filtering.

It should be noted that the second management network element is also a network element serving the terminal device. It can be understood that the second management network element may also receive other filtering services for other terminal devices, that is, the second management network element may also be a network element serving other terminal devices.

It should be noted that step 505 may be executed before step 504, or may be executed simultaneously with step 504, which is not limited in this application.

506. And the second management network element deactivates or updates the first filtering rule according to the fourth indication information.

In order to base each network element performing filtering paging traffic on the same filtering rule for the same terminal (SIM card), the second managing 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 may 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 is not described herein again.

Optionally, when the terminal device is switched from the first network to the second network, the second management network element and the leave first network of the terminal device may also re-enable the first filtering rule. If the first indication information sent by the first management network element to the second management network element before is used to indicate that the first filtering rule is disabled, indication information may be sent to the second management network element by the first management network element, where the indication information may be used to indicate that the second management network element re-enables (activates) the first filtering rule (enable filtering filter).

If the fourth indication information previously sent by the first management network element to the second management network element is used to indicate that the first network updates the first filtering rule, the indication information sent by the first management network element may be received again, where the indication information includes the first filtering rule, and the indication information may indicate that the second management network element replaces the currently used filtering rule with the first filtering rule.

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 send the indication information to the second management network element again, where the indication information includes priority information, and the priority information may indicate that the priority of the first filtering rule is the highest priority, and then the second management network element performs filtering based on the first filtering rule.

If the first filtering rule and the third filtering rule are stored in the current second management network element, the third filtering rule is a valid filtering rule, and the first filtering rule is an invalid filtering rule, the first management network element can send indication information to the second management network element again, wherein the indication information comprises valid information, 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.

In one implementation, the context information of the terminal device includes a first filtering rule, and 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 a service for the terminal device using the first filtering rule. The context information of the terminal device may refer to context information related to a multi-card function in the context information of the terminal device. Therefore, the first management network element informs the second management network element to reserve the context information of the terminal device.

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 further notify the second management network element of reserving context information of the terminal device through the fourth indication information. That is, the fourth indication information is also used to indicate that the second management network element reserves the context information of the terminal device. The context information of the terminal device may refer to context information related to a multi-card function in the context information of the terminal device.

In one implementation manner, the first management network element may further send fifth indication information to the second management network element, where the fifth indication information is used to indicate that the second management network element reserves the context information of the terminal device. The context information of the terminal device may refer to context information related to a multi-card function in the context information of the terminal device.

In an implementation manner, after receiving the first indication information, if the first indication information is further used to indicate the first management network element to delete the context information of the terminal device, the first management network element further needs to notify the second management network element to delete the context information of the terminal device. Wherein the indication of deleting the context information may be carried in the fourth indication information. That is, the first management network element sends fourth indication information to the second management network element, and the fourth indication information may indicate the second management network element to delete the context information of the terminal device, in addition to indicating the second management network element to deactivate or update the first filtering rule. The context information of the terminal device refers to the context information of the terminal device related to the multi-card function.

For example, please refer to fig. 6 together, and fig. 6 is a flowchart illustrating a method for acquiring a service in a 5G network architecture according to an embodiment of the present application. Fig. 6 illustrates the application to 5G as an example, and as shown in fig. 6, the first network includes UE, RAN, AMF, SMF, and UPF. Taking a first management network element as AMF and a second management network element as RAN, SMF and UPF as examples, 601, and sending a first filtering rule to the first management network element (AMF) by a terminal device (UE); 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. a terminal device (UE) sends first indication information to a first management network element (AMF), wherein the first indication information is used for indicating the first management network element to stop using or updating a first filtering rule; 604. and after receiving the first indication information, the first management network element (AMF) sends fourth indication information to the second management network element (RAN, SMF, UPF), wherein the fourth indication information is used for indicating the second management network element to deactivate or update the first filtering rule.

Referring to fig. 7, fig. 7 is a schematic diagram of a user interface for setting a paging service by a user according to an embodiment of the present application, as shown in fig. 7, the user interface may include a status bar, a SIM card management menu, a scroll bar, and a completion and cancellation control. The status bar may include, among other things, the name of the operator (e.g., china mobile), time, WI-FI icon, signal strength, and current remaining power. The status bar may also contain a bluetooth icon, an icon of the application when the application has notification information, and the like. The SIM card management menu may include: management of SIM cards 1 and 2 and paging management of SIM card 1. The completion control is used for selecting the control after the user finishes setting, and the cancellation control is used for selecting the control when the user abandons the setting. It should be noted that, in fig. 7, only by way of example of paging management of the SIM card 1, after the user has set paging management of the SIM card 1, the user may also set paging management of the SIM card 2.

Specifically, taking the example that the terminal device is equipped with two SIM cards, the user interface can display information of the two SIM cards, as shown in fig. 7, the operator of the SIM card 1 is china mobile, and the number of the SIM card 1 is 12345678910; the operator of the SIM card 2 is China telecom, and the number of the SIM card 2 is 12345678911; a selection box is arranged beside the two pieces of SIM card information, and the selection box is used for the user to select whether to use the SIM card, for example, the user may select not to use the SIM card, may select to use one SIM card, may select to use two SIM cards, and in fig. 7, the user selects to use two SIM cards as an example.

Further, if the user selects to use the SIM card 1, the user may set the paging management of the SIM card 1, as shown in fig. 7, the SIM card 1 may have a default filtering rule, such as the first filtering rule, and may also have other default filtering rules. The user may or may not choose to use the first filtering rule for SIM card 1, i.e. deactivate the first filtering rule. The user may also select a customized paging service, for example, the user may select a voice service, a short message service, and a data service for the SIM card 1 to select respectively, and optionally, the voice service, the short message service, and the data service may further be set for different application programs. Alternatively, the user can select the service for the SIM card 1 by one key, i.e. the full selection box shown in fig. 7. After the user finishes selecting, the user can touch the finishing 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 the second filtering rule to the network corresponding to the SIM card 1 for updating.

In the embodiment of the application, in the method for acquiring the service, the terminal device sends the filtering rule to the network after accessing the network, so that the paging service is limited based on the filtering rule, and therefore, the terminal device can receive the paging initiated by the network after filtering based on the first filtering rule, and can also send the indication information to the network for stopping or updating the filtering rule, so that the use of a user can be ensured, the terminal device can also be ensured to acquire the services of a plurality of networks, the flexibility of using and adjusting the filtering rule of the terminal device is increased, and the stability of acquiring the service by the terminal device is improved.

Based on the above description, please refer to fig. 8, fig. 8 is another flowchart of a method for acquiring a service according to an embodiment of the present application, where the method for acquiring a network service may be implemented by a terminal device, a first management network element, and a second management network element in an interactive manner, and the method for acquiring a service may include the following steps 801 to 804.

It should be noted that the same or similar parts between the various embodiments in this application may be referred to each other. In the embodiments and the implementations/implementation methods in the embodiments in the present application, unless otherwise specified or conflicting in terms of logic, terms and/or descriptions between different embodiments and between the implementations/implementation methods in the embodiments have consistency and may be mutually cited, and technical features in different embodiments and implementations/implementation methods in the embodiments may be combined to form a new embodiment, implementation method, or implementation method according to the inherent logic relationship. The above-described embodiments of the present application do not limit the scope of the present application. Wherein:

801. and the terminal equipment sends the third indication information to the first management network element.

The terminal device may detect the states of two current SIM cards, and if one SIM card is unavailable, the terminal device sends third indication information to the first management network element of the corresponding network through the available SIM card, where the third indication information is used to indicate 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 may be deleted, that is, after the context information related to the multi-card function is deleted, the context information of the terminal device (for example, the context information related to the single-card function) still exists in the network corresponding to the available SIM card.

In a possible implementation manner, the third indication information may be carried in a Tracking Area Update (TAU) request, an attach (attach) request, or a service request (service request), which is not limited in this application.

It can be understood that when the terminal device is used by two cards, and when both of the two cards in the terminal device are available, the terminal device may obtain the service of the first network and the service of the second network based on the used first SIM card and second SIM card, and the interval between the terminal device accessing the first network and switching to access the second network is relatively short, so that the terminal device is in a state of returning to the network in a short period for the first network and the second network. Similarly, when the terminal device is used as a single card, the time interval between the terminal device accessing the first network and the terminal device switching to access the second network is relatively long, and therefore, for the first network and the second network, the terminal device is in a long-term return (long time return) network state.

When the terminal equipment is used by a single card, a user can set one SIM card in the terminal equipment to be unavailable through a software program. The user may also physically remove a SIM card and only leave a SIM card in the terminal device. That is, the terminal device may detect whether a user makes one card in the terminal device unusable, i.e., set to be used by a single card, by means of a software program. The terminal equipment can also detect that two card slots are arranged in the current terminal equipment, each card slot can be provided with one SIM card, but one SIM card is removed, namely, only one SIM card reserved in the card slot can be detected.

Specifically, the third indication information may include information of the terminal device used to indicate that the terminal device is in a long-term return state, so that the first management network element may delete the context information of the terminal device after receiving the third indication information, where the context information of the terminal device is context information related to the dual card function in the context information of the terminal device.

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, the first management network element may delete the context information of the terminal device after receiving the third indication information, where the context information of the terminal device is context information related to the dual card function in the context information of the terminal device.

In an implementation manner, a terminal device sends seventh indication information to a first management network element of a first network through a second SIM card, where the seventh indication information is used to indicate the first management network element to delete context information of the terminal device, and the context information includes the first filtering rule. The first SIM card is a card that is not available in the terminal device, the second SIM card is a card that is available in the terminal device, the SIM card that is available in the terminal device can send seventh indication information to the first management network element corresponding to the SIM card that is not available, where the seventh indication information is used to indicate the first management network element to delete the context information of the terminal device, that is, delete the context information related to the dual-card function in the context information of the terminal device.

802. And the first management network element deletes the context information according to the third indication information.

In an implementation manner, after receiving the third indication information, the first management network element may know that the terminal device is in the long time return state, and may delete the context information of the terminal device based on the indication of the third indication information, where the context information is context information related to a 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 context information of the terminal device can be deleted without the first filtering rule.

In an implementation manner, similarly, the first management network element may delete the context information of the terminal device according to the seventh indication information.

803. And the first management network element sends the sixth indication information to the second management network element.

804. And the second management network element deletes the context information according to the sixth indication information.

The method comprises the steps that each network element which is used for executing the filtering paging service in a network corresponding to an available SIM card in the terminal equipment aims at the available SIM of the terminal equipment and realizes the service filtering of the terminal equipment based on a filtering rule related to a multi-card function. Therefore, when the terminal device is a terminal device used by a single card, the second management network element in the network corresponding to the available SIM card in the terminal device may delete the context of the terminal device, and the context information of the terminal device includes the filtering rule. Therefore, the first management network element may send sixth indication information to the second management network element, where the sixth indication information is used to indicate the second management network element to delete the context information of the terminal device. And after receiving the sixth indication information, the second management network element deletes the context information of the terminal device according to the indication of the sixth indication information, wherein the deleted context information is the context information related to the multi-card function in the context information of the terminal device.

It should be noted that step 802 may be executed before step 803, or may be executed simultaneously with step 803, which is not limited in this application.
