Currently, for a terminal device (e.g., a mifi device capable of inserting a SIM card or a device such as a mobile phone charger capable of inserting a SIM card) having a mobile router function and using a SIM card or a built-in chip eSIM card, when switching a network slice, an operation process is cumbersome, for example, a user generally needs to perform the following operations: firstly, a user needs to open a setting page corresponding to switching of a network slice on a terminal device, and then manually input related information of the network slice in a network slice information input window of the setting page according to an instruction of the setting page, for example, network slice identification information for identifying the network slice such as network slice ID of the network slice, operator information of the network slice, and the like are input.
Based on the existing problems, an embodiment of the present invention provides a method for switching a network slice, which is shown in fig. 1 and includes the following steps:
step S110: when the terminal device detects that a preset event occurs, target network slice identification code information carried by the current identification card and an identification card identifier of the current identification card are acquired from the current identification card selected by the switching button.
Specifically, this step is applied to the terminal device. The switching button is a switching button arranged on the terminal equipment. The terminal equipment is provided with at least two identity identification cards, and the switching button is used for connecting any one of the at least two identity identification cards into the terminal equipment.
Any one of the identity identification cards carries the network slice identification code information of the unique network slice (namely, each identity identification card carries the network slice identification code information of the unique network slice), and different identity identification cards carry the network slice identification code information of different network slices. For example, the following steps are carried out: the terminal equipment is provided with an identity recognition card 1 and an identity recognition card 2, the identity recognition card 1 carries network slice identification code information 1 of a network slice 1, the identity recognition card 2 carries network slice identification code information 2 of a network slice 2, and the network slice 1 and the network slice 2 are different network slices. In a specific implementation, the network slice identifier code information of different network slices carried by different id cards may include: the network slice identification code information carried by the at least two identity recognition cards is not null information (null information is that no information is contained), and the same network slice identification code information does not exist in the network slice identification code information carried by the at least two identity recognition cards; or the network slice identification code information carried by the at least two identity recognition cards is not null information, and at least one pair of the same network slice identification code information exists in the network slice identification code information carried by the at least two identity recognition cards, wherein the identity recognition cards of the same network slice identification code information have different operators; or, there is network slice identification code information carried by at least one identity card as null information in at least two identity cards, the network slice identification code information carried by other identity cards (i.e. identity cards except for the network slice identification code information as null information in at least two identity cards) is not null information, and the same network slice identification code information does not exist in the network slice identification code information carried by other identity cards; or, the network slice identification code information carried by at least one identity card is null information in at least two identity cards, and at least one pair of same network slice identification code information exists in the network slice identification code information carried by other identity cards, wherein the identity cards of the same network slice identification code information have different operators. In a specific implementation, the network slice identification code information may include identification information capable of identifying a network slice, such as a network slice identification code.
The setting mode of the switching button can be various. Several alternatives are listed below.
Specifically, in an alternative, the switching button may include: a physical toggle button. The physical switch button may perform a selection operation, for example, the physical switch button may perform an AB selection, as shown in fig. 2, a may be regarded as the identification card 1, and B may be regarded as the identification card 2. Specifically, fig. 2 shows a schematic structural diagram of a physical switching button provided on a terminal device. Pins are arranged on the physical switching button and the identity card shown in fig. 2, and when the pin of the identity card 1 is connected to the pin of the physical switching button, the physical switching button connects the identity card 1 to the terminal device; similarly, when the pin of the identification card 2 is connected to the pin of the physical switch button, the physical switch button connects the identification card 2 to the terminal device. Of course, it is understood that the setting manner of setting the physical switch button on the terminal device shown in fig. 2 is only an example, and in a specific implementation, as long as any one of at least two identification cards on the terminal device can be connected to the terminal device through the physical switch button, the setting manner of the physical switch button is not limited in the present invention. In specific implementation, a user may access different identification cards to a terminal device by performing corresponding operation on a physical switching button (for example, performing a toggle operation on the physical switching button shown in fig. 2), so that the terminal device obtains target network slice identification code information and an identification card identifier carried by the identification card from a current identification card, so as to send the obtained information to a core network in a subsequent step (corresponding to step S120), and the core network accesses the terminal device to a corresponding target network slice according to the target network slice identification code information and the identification card identifier. Therefore, in the embodiment of the invention, the user can select different network slices by only connecting different identity identification cards into the terminal equipment through the physical switching button on the terminal side, the operation is simple, convenient and quick, the user does not need to execute the complicated operation of inputting the network slice information in the switching interface, and the switching operation process of the network slices is greatly simplified.
In another alternative, the toggle button may include: and touching a switching button. Specifically, there may be multiple setting manners of the touch switching button, for example, in an optional setting manner of the touch switching button, the touch switching button may be a touch switching button for switching operations, which is set on a touch interface of the terminal device, and after the touch switching button is clicked, the current id card of the access terminal device may be switched to a next id card in a preset switching sequence according to the preset switching sequence (the preset switching sequence may be set by a person skilled in the art according to an actual situation, which is not limited by the present invention). Specifically, referring to fig. 3a, two identification cards are provided on the terminal device, and the preset switching sequence of the two identification cards is as follows: an identification card 1 and an identification card 2. If the identity recognition card of the current access terminal is the identity recognition card 1, after the touch switching button is clicked, the identity recognition card of the current access terminal is converted from the identity recognition card 1 into the identity recognition card 2. In another optional setting manner of the touch switching button, the touch switching button may be at least one touch switching button for selecting operation, which is set on the touch interface, each touch switching button corresponds to one identification card, and after a corresponding operation is selected to be performed on any touch switching button in the touch interface (for example, a click operation is performed, which does not limit the operation form), the identification card corresponding to the currently selected touch switching button may be inserted into the terminal device. As shown in fig. 3b, if the operation performed on the touch switching button is a click operation, and if the touch switching button corresponding to the identification card 1 is clicked, the identification card 1 is accessed to the terminal device; similarly, if a touch switching button corresponding to the identity identification card n is clicked, the identity identification card n is accessed to the terminal equipment, wherein n is a natural number and n is more than or equal to 1. It is understood that the above-listed setting manners of the touch switch button are merely exemplary, and in particular implementations, the setting manners of the touch switch button include, but are not limited to, the above-listed setting manners. Similar to the physical switching button, when switching network slices, a user only needs to directly select the identity card selected by the touch switching button through the touch switching button, so that the terminal device obtains the target network slice identification code information and the identity card identifier carried by the identity card from the current identity card, and the obtained information is conveniently sent to the core network in the subsequent step (corresponding to step S120), so that the core network accesses the terminal device to the corresponding target network slice according to the target network slice identification code information and the identity card identifier, and the switching operation process is simple, convenient and quick.
It is understood that the above listed arrangement of the switch button is merely exemplary, and in particular embodiments, the arrangement of the switch button includes, but is not limited to, the above listed arrangement.
In a specific implementation, the identification card may include: a SIM card, and/or an eSIM card. Then, in this embodiment of the present invention, the terminal device may include: a terminal device having a mobile router function and using a SIM card or a chip-embedded eSIM card, for example, a mifi device into which a SIM card can be inserted or a device such as a power bank into which a SIM card can be inserted.
Specifically, in this step, the preset event may include: the switching button is switched from other identification cards to the current identification card, or is switched on for operation and the like which require to be accessed into the identification card again. The current identification card is an identification card accessed to the terminal equipment through a switching button, and the other identification cards are identification cards except the current identification card in at least two identification cards arranged on the terminal equipment.
In a specific implementation, after the current identification card selected by the switch button is switched, other identification cards may be in an offline state or a preset online state. Wherein, the preset network state may specifically be: other identification cards are registered in the core network, and after the current identification card selected by the button is switched, the other identification cards can also carry out normal communication and transmit small data. In a specific implementation, the bandwidth of the small amount of data is smaller than a preset threshold, and the preset threshold may be set by a person skilled in the art according to an actual situation, which is not limited by the present invention.
Step S120: the terminal equipment sends a request message carrying target network slice identification code information and an identification card identifier to a core network through an access network.
The step is applied to a terminal device, and the terminal (i.e. the terminal device) sends the target network slice identification code information and the identification card identifier obtained in the step S110 to the core network through the access network, so that the core network determines the target network slice according to the target network slice identification code information and the identification card identifier, and accesses the terminal device to the target network slice. In a specific implementation, the target network slice may include: private networks, or public networks.
Step S130: and the core network receives a request message which is sent by the terminal equipment through the access network and carries the target network slice identification code information and the identification card identification.
This step is applied to the core network. In this step, the core network receives a request message carrying target network slice identification code information and an identification card identifier, which is sent by the terminal device through the access network, and a receiving manner of receiving the request message may be set by a person skilled in the art according to an actual situation, which is not limited by the present invention.
Step S140: and the core network determines the target network slice according to the target network slice identification code information and the identification card identifier, and accesses the terminal equipment into the target network slice.
Specifically, the execution process of this step can specifically refer to fig. 4, and includes:
step S410: and judging whether the target network slice identification code information is null information, if not, executing the step S420, and if so, executing the step S450.
The target network slice identification code information comprises two states of existence or nonexistence, when the target network slice identification code information does not exist, the target network slice identification code information is null information, otherwise, the target network slice identification code information is not null information. In specific implementation, when the target network slice identifier information is not null information, the target network slice identifier information includes: a target network slice identity.
Step S420: the core network acquires network slice subscription information corresponding to the identification card identifier.
Specifically, the network slice subscription information may include a correspondence between a preset network slice identification code and a network slice. In this step, network slice subscription information corresponding to the identification card identifier is obtained from the core network according to the identification card identifier. The preset correspondence between the network slice identification code and the network slice may be set by a person skilled in the art according to actual conditions, which is not limited in the present invention.
Step S430: judging whether a target network slice identification code exists in the preset network slice identification codes, if so, executing step S440; if not, go to step S450.
Step S440: and taking the network slice corresponding to the target network slice identification code as a target network slice according to the corresponding relation between the preset network slice identification code and the network slice, and accessing the terminal equipment into the target network slice.
And searching a network slice corresponding to the target network slice identification code in the corresponding relation between the preset network slice identification code and the network slice, taking the network slice corresponding to the target network slice identification code as the target network slice, and accessing the terminal equipment into the target network slice.

In specific implementation, the general network slice may be set by a person skilled in the art according to actual situations, for example, setting the public network as the general network slice, or setting a commonly used network slice as the general network slice, and so on. The alert message may include: a network access refusal message is sent to the terminal device, for example, so as to pop up a text prompt "network access is not allowed" in a display interface of the terminal device to prompt a user that the network access is not allowed currently; or the prompt message may include a retry access network message, for example, a retry access network message is sent to the terminal device, so that a text prompt "please retry access network" pops up on a display interface of the terminal device to prompt the user that the network cannot be accessed or to prompt the user to retry access the network, and so on.
The following describes an embodiment of the present invention in detail with reference to a specific embodiment. Specifically, if be provided with two identification card on the terminal equipment, include: the terminal equipment is provided with a physical switching button in a mode shown in figure 2, and when a user accesses the identity recognition card 1 into the terminal equipment through the physical switching button, the terminal equipment is accessed into the public network; similarly, when the user accesses the identification card 2 to the terminal device through the physical switch button, the terminal device accesses the private network.
