[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

For example, some operations / steps may also be decomposed, combined or partially merged, so the actual execution order may change according to actual conditions.

As used in this application specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0025] It should be further understood that the term “and / or” used in the specification and appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0026] The embodiments of the present application provide a network slice access method, device, system and storage medium. Some implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0027] See also Figure 1 , Figure 1 is a schematic flow chart of a network slicing access method provided in an embodiment of the present application. The method can be applied to a terminal device. For example, the terminal device can be a user's mobile phone, such as Figure 1 As shown, the network slice access method specifically includes steps S101 to S103.

[0028] S101. Determine an accessed communication address, wherein the accessed communication address includes a communication address corresponding to an accessed network slice.

[0029] Among them, multiple network slices are pre-configured in the network equipment. Different network slices correspond to different business functions. Terminal devices can access network slices in network devices according to needs. According to the definition of the 3rd Generation Partnership Project (3GPP), a terminal device can access eight network slices at the same time. The network equipment can be a base station, and the network slice can be configured by the operator or by a third-party company.

[0030] Different network slices have their own corresponding communication addresses. For example, the communication address can be an Internet Protocol (IP) address. The terminal device can send a slice access request to the network device, and the network device will return the communication address of the network slice to be accessed to the terminal device. The terminal device can then access the corresponding network slice based on the received communication address.

[0031] The terminal device may have accessed several network slices in advance, and if the user has other business function requirements later, it can access new network slices. The network slice that the terminal device has currently accessed can be determined, and the communication address corresponding to each network slice can be obtained and determined as the accessed communication address.

[0032] S102. Send the slice access request and the accessed communication address to the network device, so that the network device determines the target network slice according to the slice access request, and determines the target communication address for the target network slice according to the accessed communication address, wherein the target communication address and the accessed communication address are different.

[0033] Among them, the slice access request is a request signaling used to apply to the network device for access to a new network slice. The network slice corresponding to the slice access request can be set according to the actual needs of the user and is not limited here.

[0034] At the same time, the slice access request and the determined accessed communication address are sent to the network device. The network device can determine that the terminal device needs to access a new network slice based on the slice access request, and then determine the corresponding target network slice based on the slice access request.

[0035] The network device can assign a communication address to a determined target network slice. If the network device randomly assigns a communication address to a target network slice, it is likely that the same communication address will be configured for different network slices. If the terminal device has previously accessed a network slice with a communication address, the terminal device will not be able to access a subsequent network slice with the same communication address.

[0036] Therefore, by sending the accessed communication address to the network device so that the network device can determine the network slice to which the terminal device has accessed and the communication address that is already in use, the network device can avoid reallocating the already used communication address when configuring the communication address for the target network slice, and can select a communication address that is different from the communication address in the accessed communication address as the target communication address of the target network slice.

[0037] S103. Receive the target communication address returned by the network device, and access the target network slice according to the target communication address.

[0038] Among them, after the network device determines the target network slice and the target communication address, it can send the allocation result to the terminal device. The allocation result may include whether the allocation is successful and the target communication address.

[0039] The terminal device can determine whether the allocation is successful based on the allocation result returned by the network device, and access the corresponding target network slice according to the received target communication address to complete the access to the new network slice.

[0040] In one embodiment, the operation of accessing the target network slice according to the target communication address may be implemented as follows:

[0041] If the target communication address and the accessed communication address are not the same, the target network slice is accessed according to the target communication address.

[0042] Among them, when the target communication address returned by the network device is received, it can be further determined whether the target communication address and the communication address corresponding to the accessed network slice included in the accessed communication address are the same. When the target communication address and the communication address corresponding to the accessed network slice included in the accessed communication address are not the same, the target network slice is accessed according to the target communication address to avoid the problem of communication address conflict caused by the received target communication address and the communication address corresponding to the accessed network slice included in the accessed communication address being the same.

[0043] If the target communication address is the same as the communication address corresponding to the accessed network slice included in the accessed communication address, the operation of determining the accessed communication address and sending the slice access request and the accessed communication address to the network device can be returned to apply again.

[0044] In one embodiment, the method further comprises the following operation: adding the target communication address to the accessed communication address.

[0045] Among them, after accessing the target network slice according to the target communication address, the target communication address is added to the accessed communication address; after accessing the target network slice according to the target communication address, it indicates that the target network slice is already one of the network slices currently accessed by the terminal device, so the target communication address can be added to the accessed communication address.

[0046] The method provided in the embodiment of the present application determines the communication address of the network slice that the terminal device has already accessed and sends it to the network device, so that the network device can determine the communication address already used in the terminal device for the newly accessed network slice, thereby avoiding conflicts between the communication addresses of the newly accessed network slice and the already accessed network slice, and improving the efficiency of the terminal device accessing the network slice.

[0047] In one embodiment, the method further comprises the following operations:

[0048] When a slice release event is detected, the communication address of the network slice corresponding to the slice release event is determined; and the communication address of the network slice corresponding to the slice release event is removed from the accessed communication address.

[0049] If a terminal device no longer needs to use a certain service function, it can cancel access to the corresponding network slice, and the terminal device can send a slice release application to the network device; the network device can also actively cancel the terminal device's access to a certain network slice. It can be determined that a slice release event is detected when it is detected that the terminal device sends a slice release application to the network device, or when it is detected that the network device actively cancels the connection between the terminal device and a network device. If the terminal device no longer has access to a network slice, the communication address corresponding to the network slice can be removed from the accessed communication address.

[0050] See also Figure 2 , Figure 2 is a schematic flow chart of another network slice access method provided by an embodiment of the present application, which method can be applied to a network device, for example, the network device can be a base station, such as Figure 2 As shown, the network slice access method specifically includes steps S201 to S203.

[0051] S201. Receive a slice access request and an accessed communication address sent by a terminal device, wherein the accessed communication address includes a communication address corresponding to the network slice to which the terminal device has accessed.

[0052] Among them, the terminal device can determine the network slice that is currently connected, and obtain the communication address corresponding to each network slice, and determine it as the connected communication address. When the terminal device needs to access a new network slice, it can send a slice access request and the connected communication address to the network device.

[0053] S202. Determine a target network slice according to the slice access request, and determine a target communication address for the target network slice according to the accessed communication address, wherein the target communication address and the accessed communication address are different.

[0054] The slice access request is a request signaling used to apply to the network device for access to a new network slice. The network slice corresponding to the slice access request can be set according to the actual needs of the user. The network device can determine the target network slice based on the received slice access request as the new network slice accessed by the terminal device.

[0055] The network device can determine the network slice that has been accessed and the communication address that is already in use in the terminal device based on the accessed communication address. The network device determines the target communication address for the target network slice based on the accessed communication address, thereby avoiding the reallocation of the communication address that has been used.

[0056] S203: Send the target communication address to the terminal device.

[0057] After determining the target network slice and the target communication address, the network device can send the target communication address to the terminal device so that the terminal device can access the target network slice according to the target communication address. The network device can send the allocation result to the terminal device, and the allocation result may include whether the allocation is successful and the target communication address.

[0058] In one embodiment, the operation of determining the target communication address for the target network slice according to the accessed communication address may be implemented in the following manner:

[0059] Determine a first communication address that is different from the accessed communication address; determine the first communication address as the target communication address of the target network slice.

[0060] Among them, the network device selects a communication address that is different from the communication addresses corresponding to the accessed network slices included in the accessed communication address as the target communication address, so that the terminal device can successfully access the target network slice according to the target communication address, avoiding the problem of inability to access due to address conflicts.

[0061] The method provided in the embodiment of the present application determines the communication address of the network slice that the terminal device has already accessed and sends it to the network device, so that the network device can determine the communication address already used in the terminal device for the newly accessed network slice, thereby avoiding conflicts between the communication addresses of the newly accessed network slice and the already accessed network slice, and improving the efficiency of the terminal device accessing the network slice.
