In the related art, in the fifth generation (5G) independent networking (SA, Standalone) communication network system, network slicing services can be supported. During the process of the terminal initiating the registration of network slices, if the slice service type is rejected by the network, the network side sends the rejected slice set (rejected NSSAI) to the terminal through the registration accept message, informing the terminal that these slice types are rejected. , and will bring a specific rejected cause. The rejected cause values mainly include the following two: The first cause value: "Network slice not available in the current PLMN", indicating that under the currently resident PLMN, The slice service is unavailable; the second reason value: "Network slice not available in the current registration area", indicating that the slice service is unavailable in the currently residing registration area (RA, Registration Area). FIG. 1 is a schematic flowchart of a terminal initiating slice registration in the related art. As shown in FIG. 1 , the terminal sends a registration request (registration request) message to the network side; the network side sends a registration accept (registration accept) message to the terminal; The registration accept message carries the rejected NSSAI set and the first cause value. Figure 2 is another schematic flowchart of a terminal initiating slice registration in the related art. As shown in Figure 2, the terminal sends a registration request message to the network side; the network side sends a registration accept message to the terminal; the registration accept message carries the rejected NSSAI set and the second cause value.

To sum up, after the terminal completes the 5G SA registration slice, if the slice corresponding to an application of the terminal is included in the rejected NSSAI set, the slice service cannot be initiated normally, and the slice service cannot be used.

Based on this, in various embodiments of the present application, when it is determined to initiate a slice registration process, the terminal performs the following operations: determine the identification information of the first network slice corresponding to the first slice service; The first PLMN corresponding to the identification information of the first network slice; the first PLMN list stores the correspondence between the network slice identifier and the PLMN; the first network slice does not refuse to register on the first PLMN history or record; select the first registration area corresponding to the identification information of the first network slice from the first registration area list; the first registration area includes at least one cell; The first cell corresponding to the first PLMN; the first registration area list stores the correspondence between the network slice identifier and the registration area; the first network slice does not have a history or record of refusing registration on the first cell ; Send a slice registration request to the base station to which the first cell belongs; the slice registration request carries the identification information of the first network slice.

The present application will be described in further detail below with reference to the accompanying drawings and specific embodiments.

An embodiment of the present application provides a network slice registration method, which is applied to a terminal. FIG. 3 is a schematic diagram of an implementation flow of the network slice registration method according to an embodiment of the present application; as shown in FIG. 3 , the method includes:

Step 301: Determine the identification information of the first network slice corresponding to the first slice service;

Step 302: Select the first PLMN corresponding to the identification information of the first network slice from the first PLMN list; the first network slice has no registration history or record on the first PLMN; the first network slice has no registration history or record; A PLMN list stores the correspondence between network slice identifiers and PLMNs.

Step 303: Select a first registration area corresponding to the identification information of the first network slice from the first registration area list; the first registration area includes at least one cell; The first cell corresponding to the first PLMN; the first network slice has no registration history or record of rejection on the first cell; the first registration area list stores the correspondence between the network slice identifier and the registration area;

Step 304: Send a slice registration request to the base station to which the first cell belongs; the slice registration request carries the identification information of the first network slice.

In this embodiment of the present application, when the terminal determines to initiate a slice registration process, the terminal performs steps 301 to 304.

Here, in step 301, the terminal may determine the identification information of the first network slice according to the service of the first application. For example, assuming that the service of the first application is a video service, the identification information of the first network slice corresponding to the first application may be represented by slice 0; or, assuming that the service of the first application is browsing server service, the identification information of the first network slice corresponding to the first application may be represented by slice 1. The network slice may refer to an end-to-end logical private network capable of providing specific network capabilities. A network slice instance may refer to a collection of network functions and required physical/virtual resources, and may specifically include an access network, a core network, a transmission bearer network, and applications.

Here, in step 302, from the perspective of the terminal user, the slicing service subscribed by the terminal is based on PLMN, the slicing service subscribed by the user under different PLMNs may be different, the same slicing service subscribed under some PLMNs, but in other May not be contracted under PLMN. In addition, in the actual network deployment environment, at the same location, networks corresponding to multiple PLMNs can be covered; if the slice service required by the first application of the terminal is rejected on one of the PLMNs, but permitted on other PLMNs Therefore, you can try to select another PLMN to reselect the network, reselect the cell corresponding to the PLMN for camping, and initiate a slice registration request in the camping cell, thereby improving the success rate of slice registration and improving the slice service. The probability of initiation ensures the normal operation of the slice service.

Here, in step 303, the first network slice has no registration history or record of rejection on the first cell, that is, the first network slice has no registration area corresponding to the first cell. There is a history or record of denial of registration. For example, the first cell is represented by cell 1, and the registration area corresponding to cell 1 is represented by RAID 1. If RAID 1 includes cell 1, cell 2, cell 3, and cell 4, the first network slice is included in RAID 1. There is no history or record of refusal to register on the cell 1, cell 2, cell 3, and cell 4.

Here, in step 303, from the network level, in the actual network deployment environment, the network slicing capabilities are not completely continuous, and the slicing services supported by different network environments may be different. Taking RA as the unit, the slices supported under the same RA The services are the same, but the slicing services supported by different RAs may be different; if the slicing service required by the terminal's first application is unavailable in one of the RAs, it may be available in other RAs. Therefore, in the reselection network After that, it can camp on the cells corresponding to other RAs, and initiate a slice registration request in the cells corresponding to other RAs, thereby improving the success rate of slice registration, thereby improving the probability that the slice service can be successfully initiated, and ensuring the normal operation of the slice service.

In practical application, all network slices and corresponding PLMNs that are refused registration by the network can be temporarily added to the forbidden plmn list, when the first PLMN corresponding to the identification information of the first network slice is selected from the first PLMN list. , all PLMNs corresponding to the first network slice in the forbidden plmn list can be excluded from the first PLMN list, and the identification information of the first network slice can be selected from the remaining PLMNs in the first PLMN list The corresponding first PLMN.

Based on this, in an embodiment, the selecting the first PLMN corresponding to the identification information of the first network slice from the first PLMN list includes:

Generate the second PLMN list; what the second PLMN list stores is the correspondence between the network slice and the PLMN that the network refuses to register;

All PLMNs corresponding to the first network slice in the second PLMN list are excluded from the first PLMN list; The first PLMN corresponding to the identification information.

Here, the second PLMN list may refer to a temporarily generated forbidden plmn list. After the slice registration process is completed, the plmn temporarily added to the forbidden plmn list may be deleted, that is, the normal forbidden plmn list is restored.

Here, the second PLMN list can be represented by Table 1. As shown in Table 1, the network slices whose registration is rejected by the network include slice 1, slice 2 and slice 3, wherein slice 1 is rejected by the network side on PLMN0 and PLMN1 Registration, slice 2 is refused registration by the network side on PLMN2 and PLMN3, and slice 3 is refused registration by the network side on PLMN4, PLMN5 and PLMN6. The PLMN corresponding to the slice can be obtained by combining the MCC and the MNC, where the MCC can be represented by a 3-digit number, and the MNC can be represented by a 2-digit number.

Here, the first PLMN list is represented by Table 2. As shown in Table 2, assuming that the first network slice is represented as slice 3, when the PLMN corresponding to slice 3 is selected from Table 2, since the PLMN in Table 1 corresponds to slice 3 All PLMNs in Table 2 include PLMN4, PLMN5, and PLMN6, and all PLMNs corresponding to slice 3 in Table 2 include PLMN0, PLMN1, PLMN2, PLMN3, PLMN4, PLMN5, and PLMN6. In this way, PLMN4, PLMN5, and PLMN6 are excluded from Table 2, And select the PLMN corresponding to slice 3 from the remaining PLMNs in Table 2, that is, PLMN0, PLMN1, PLMN2, PLMN3, and randomly select a PLMN such as PLMN3 from PLMN0, PLMN1, PLMN2, and PLMN3 to search the network to access the network. .

In practical applications, the terminal can maintain a data record table A locally, and the data record table A is used to record the network slices whose registration is rejected by the network; the reasons for rejection may include: terminal arrears, terminal unsubscribed, current PLMN does not allow slice registration, etc. Wait. Among them, according to the rejected NSSAI set issued by the network side, it can be determined that the reason for the rejection of the network slice registration is that the current PLMN does not allow registration. In this way, the terminal can temporarily add the PLMNs that refuse slice registration to the second PLMN list according to the data record table A.

Based on this, in an embodiment, the generating the second PLMN list includes:

Obtain a first data record table; the first data record table is generated according to a first set; the first set includes at least one network slice that is refused registration by the network and a corresponding first reason value; the first reason The value indicates that the network slice is not available on the currently resident PLMN;

According to the first data record table, determine the correspondence between the network slice and the PLMN whose registration is refused by the network;

The second PLMN list is generated based on the determined correspondence between network slices and PLMNs whose registration is refused by the network.

The first set may refer to a set consisting of multiple single network slice auxiliary information (s-NSSAI, single Network Slice Selection Assistance Information), and s-NSSAI may be used to identify a network slice.

In practical application, all network slices and corresponding registration areas that are refused registration by the network can be temporarily added to the forbidden RA list, and when the registration area corresponding to the identification information of the first network slice is selected from the first registration area list , all registration areas corresponding to the first network slice in the forbidden RA list can be excluded from the first registration area list, and all registration areas corresponding to the first network slice can be selected from the remaining registration areas in the first registration area list. The identification information matches the first registration area.

Based on this, in an embodiment, the selecting the first registration area corresponding to the identification information of the first network slice from the first registration area list includes:

A second registration area list is generated; what the second registration area list stores is the correspondence between the network slice and the registration area that are refused registration by the network;

Excluding all registration areas corresponding to the first network slice in the second registration area list from the first registration area list;

A first registration area corresponding to the identification information of the first network slice is determined from the remaining registration areas in the first registration area list.

Wherein, the second registration area list may refer to the temporarily generated forbidden RA list. After the slice registration process is executed, the registration area temporarily added to the forbidden RA list may be deleted, that is, the normal forbidden RA list is restored.

Here, the second registration area list can be represented by Table 3. As shown in Table 3, the network slices whose registration is rejected by the network include slice 1, slice 2 and slice 3. Taking slice 3 as an example, according to Table 3, It can be seen that slice 3 is refused registration by the network side on RAID 4 and RAID 5. Assume that RAID 4 includes cell 7 and cell 8, and RAID 5 includes cell 9 and cell 10, then slice 3 is in cell 7, cell 8, cell 9, All cells 10 are refused registration by the network side.

Here, the first registration area list is represented by Table 4. As shown in Table 4, assuming that the first network slice is represented as slice 3, when the registration area corresponding to the slice 3 is selected from Table 4, because Table 3 All registration areas corresponding to slice 3 in Table 4 include RAID 4 and RAID 5, and all registration areas corresponding to slice 3 in Table 4 include RAID 1, RAID 2, RAID 3, RAID 4, and RAID 5. In this way, from Table 4, RAID4, RAID5 are excluded, and the registration area corresponding to slice 3 is selected from the remaining registration areas in Table 4, that is, RAID1, RAID2, RAID3, and randomly selected from RAID1, RAID2, RAID3 A registration area such as RAID1 is selected as the first registration area. Assuming that RAID 1 includes cell 1, cell 2, cell 3, and cell 4, select a cell corresponding to the first PLMN, such as cell 3, from the cells included in RAID 1 to camp on. The base station to which the first cell belongs sends a slice registration request to request registration to the slice, so as to use the slice for data communication.

In practical applications, the terminal can maintain a data record table B locally, and the data record table B is used to record the network slices whose registration is refused by the network; the reasons for the rejection may include: terminal arrears, terminal unsubscribed, and the current cell does not allow cell registration. etc. Among them, according to the rejected NSSAI set delivered by the network side, it can be determined that the reason for the rejection of the network slice registration is that the currently residing cell does not allow registration. In this way, the terminal can temporarily add the cells that refuse slice registration to the second registration area list according to the data record table B.

According to the second data record list, determine the correspondence between the network slice and the registration area whose registration is refused by the network;

The second registration area list is generated based on the correspondence between the network slices whose registration is refused by the network and the registration area.

The second set may refer to a set composed of multiple s-NSSAIs, and the s-NSSAIs may be used to identify a network slice.

Here, the network slice being unavailable in the currently residing registration area may mean that the network slice is unavailable in each cell included in the registration area. For example, the registration area includes cell 1, cell 2, cell 3, and cell 4. If the network slice is refused registration by the network side in this registration area, the network slice will be blocked by the network in cell 1, cell 2, cell 3, and cell 4. side refusal to register.

In one embodiment, as shown in Figure 4, taking the 5G SA network as an example, the process of initiating a slice registration process by a terminal is described, including:

Step 401: When it is determined to initiate the slice registration process, the terminal determines the identification information of the first network slice corresponding to the first slice service.

Step 402: the terminal generates a second PLMN list; excludes all PLMNs corresponding to the first network slice in the second PLMN list from the first PLMN list; A first PLMN corresponding to the identification information of the first network slice is determined in the PLMN.

Step 403: the terminal generates a second registration area list; excludes all registration areas corresponding to the first network slice in the second registration area list from the first registration area list; A first registration area corresponding to the identification information of the first network slice is determined from the remaining registration areas in the area list.

Wherein, the second registration area list stores the corresponding relationship between the network slices and the registration areas whose registration is refused by the network.

Step 404: the terminal determines a first cell corresponding to the first PLMN from at least one cell included in the first registration area;

Step 405: The terminal sends a slice registration request to the base station to which the first cell belongs; the slice registration request carries the identification information of the first network slice.

Step 603: Generate a second registration area list based on the correspondence between the network slices whose registration is refused by the network and the registration area.

Here, the terminal initiates the slice registration process, which has the following advantages:

(1) After the terminal registers the slice in the 5G SA network, if the slice type corresponding to an application of the terminal is included in the rejected NSSAI set, according to the existing technical solution, the slice service cannot be initiated and cannot be used at this time. In this embodiment of the present application, the terminal can choose another network to reside on, and bypass those PLMNs and RAs that have been clearly known to have no license for the slice when selecting a network, so as to try to obtain the license of the slice service, thereby improving the performance of the slice service. The probability of a successful launch.

(2) The embodiment of the present application optimizes the first application scenario; the first application scenario refers to a scenario in which the slice service of the first application of the terminal is rejected on the PLMN.

Specifically, the network is reselected by trying to select a PLMN that has no registration history or record of rejection, and by trying to select other cells under the PLMN that are not rejected by the network, to obtain the permission of the slicing service of the first application of the terminal, and Compared with the method of directly rejecting slice registration and making the slice service unavailable in the related art, try to select another PLMN to re-select the network, and bypass those PLMNs that are clearly known to have no license for the slice service when selecting a cell.

Bypassing those RAs that are known to have no license for the slice to obtain the license of the slice service, thereby increasing the probability of the slice service being initiated, and ensuring the normal operation of the slice service.

In practical application, after the terminal enables the first application, if the first application is currently unavailable due to the refusal to register a slice, the user may be prompted to initiate a slice registration process to enable the first application. The application is in the available state, when the user chooses to initiate the slice registration process, the terminal can initiate the slice registration process, re-access the network by trying to select another PLMN, and try to select another cell for camping, so as to improve the slice registration process. to ensure the normal operation of the slice service.

In actual application, before detecting the opening operation for the first application, when the terminal initiates the slice registration process to the network side, if it receives the registration accept message carrying the rejected NSSAI set sent by the network side, the terminal will perform the operation according to The rejected NSSAI collection determines the network slice that was rejected by the network for registration, and sets the application associated with the network slice to an unavailable state.

Based on this, in an embodiment, the judging whether to generate prompt information includes:

Determine whether the first network slice corresponding to the first slice service has been refused registration by the network before initiating the slice registration process;

When it is determined that the first network slice corresponding to the first slice service is refused registration by the network, it is determined to generate prompt information.

Here, before initiating the slice registration process provided in the embodiment of the present application, the terminal may initiate slice registration according to the existing slice registration process, if the first network slice corresponding to the first slice service is refused registration by the network , the first application associated with the first network slice may be set to an unavailable state, for example, graying the icon of the first application, that is, the color of the icon of the first application Set to grey.

Here, the terminal may judge whether the first network slice corresponding to the first slice service has been refused registration by the network before initiating the slice registration process according to the set of rejected NSSAI sent by the network side. Specifically, when the rejected NSSAI When the set includes the identifier of the first network slice, it is determined that the first network slice corresponding to the first slice service is refused registration by the network.

In an example, as shown in FIG. 7 , the process of graying the icon of the first application program by the terminal is described, including:

The prompt information is used to prompt the user whether to start the first application by initiating a slice registration process.

Here, when it is determined that the first network slice corresponding to the first slice service is refused registration by the network, it is determined to generate prompt information.

Step 803: The terminal generates prompt information.

Here, after the user clicks to open the first application, after the terminal detects the opening operation for the first application, a dialog box pops up and a prompt message is displayed "This application slicing service is not permitted under the currently resident network, such as If you still need to use it, you can click the button below to try to initiate the slice registration process".

Step 804: The terminal receives a confirmation operation for the prompt information; in response to the confirmation operation, a slice registration process is initiated.

Here, the terminal prompts the user to choose to try to initiate the slice registration process, which has the following advantages:

After the first application program of the terminal is grayed out, the first application program is in an unavailable state. Therefore, by prompting the user to choose to try to initiate the slice registration process, it is possible to initiate the slice registration process and try to select another PLMN to restart the process. When selecting a network, bypass those PLMNs that are clearly known to have no license for the slice service when selecting a network, and bypass those RAs that are clearly known to have no license for the slice when selecting a cell to obtain the license for the slice service, thereby improving the The probability of slicing service initiation to ensure the normal operation of slicing services.

In practical application, after the network selection is completed, the terminal initiates the registration process of 5G SA. During this registration process, if the first network slice is not rejected by the network again, the slice service can be initiated normally; if the first network slice If the slice is rejected by the network again, and the rejection reason value is the first reason value, then the first network slice and the corresponding first PLMN are added to the data record table A to inform the end user that the slice service has failed to be initiated. If it is selected to try to initiate the slicing service again, the slicing service process is re-initiated.

Based on this, in an embodiment, after executing the slice registration process, the method further includes:

Determine whether the first network slice is refused registration by the network;

When it is determined that the registration of the first network slice is refused by the network, determining the reason value for the registration of the first network slice being refused by the network;

When the determined cause value is the first cause value, the identification information of the first PLMN and the first network slice is recorded in the first data record table.

In practical application, after the network selection is completed, the terminal initiates the registration process of 5G SA. During this registration process, if the first network slice is rejected by the network again, and the rejection reason value is the second reason value, the The first network slice and the registration area identifier corresponding to the first cell are added to the data record table B to inform the terminal user that the slicing service has failed to be initiated. If the terminal attempts to initiate the slicing service subsequently, the slicing service process is repeatedly initiated.

When the determined cause value is the second cause value, the registration area identifier corresponding to the first cell and the identifier information of the first network slice are recorded in the second data record table.

For example, assuming that the identification of the registration area corresponding to the first cell is RAID 3, and the identification information of the first network slice is slice 3, after the slice registration process is performed, if the first network slice is rejected by the network If registered, the corresponding relationship between slice 3 and RAID 3 is recorded in the second data record table.

In practical application, when the user chooses to initiate the slice registration process, an option button for suspending the slice registration process may be displayed on the display interface of the terminal. When the user chooses to stop the slice registration process , the terminal may stop executing the slice registration process.

Based on this, in one embodiment, the method further includes:

In the process of initiating the slice registration process, a first operation is detected; the first operation represents suspending the slice registration process;

In response to the first operation, the slice registration process is suspended.

Here, when the user wishes to suspend the slice registration process to perform other services, the terminal can restore the normal forbidden plmn list and forbidden RA list first; complete other services in the community.

With the technical solutions of the embodiments of the present application, when the terminal initiates the slice registration process, it searches for the network by trying to select a PLMN that is not rejected by the network, and tries to select a cell that is not rejected by the network to complete the camping, that is, the The terminal can bypass the PLMNs and cells rejected by the network, so as to try to obtain the permission of the first slice service, thereby improving the success rate of registration of the first network slice, thereby improving the probability of the slice service being successfully initiated. , to ensure the normal operation of slicing services.
