[0053] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0054] The slice determination method provided in the embodiment of the present application can be applied to the application environment shown in Figure 1. Among them, the terminal 102 communicates with the server 104 through the network. The data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104, or it can be placed on the cloud or other network servers. Obtain the first resource slice of the first downlink port, and the first business slice corresponding to the terminal; then, according to the first resource slice and the first business slice, determine the slice information corresponding to the terminal. Among them, the terminal 102 can be but is not limited to various personal computers, laptops, smart phones, tablets, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. Server 104 can be implemented with an independent server or a server cluster consisting of multiple servers.

[0055] In one embodiment, as shown in FIG. 2 , a slice determination method is provided, which is described by taking the method applied to the terminal 102 in FIG. 1 as an example, including the following steps:

[0056] S201: When a terminal accesses a first downlink port among downlink ports of a first optical network unit, obtain a first resource slice of the first downlink port.

[0057] It should be noted that in order to ensure the timeliness of obtaining the first resource slice of the first downlink port, the candidate resource slices corresponding to each downlink port of the first optical network unit can be determined in advance. Furthermore, when it is necessary to determine the resource slice corresponding to the first downlink port, the first resource slice of the first downlink port can be determined from the candidate resource slices corresponding to each downlink port.

[0058] In one embodiment of the present application, a storage unit that records candidate resource slices corresponding to each downlink port of the first optical network unit can be pre-set. When it is necessary to determine the first resource slice of the first downlink port, it can be searched in the storage unit according to the label of the first downlink port. If the downlink port label corresponding to a candidate resource slice is the same as the label of the first downlink port, the candidate resource slice is used as the first resource slice of the first downlink port.

[0059] Among them, resource slices are allocated to the corresponding resource slices D-NetX (X=0, 1, 2, 3, 4, 5, 6, 7, 8) according to the physical identifier (ONU-SN (ONU Serial Number) or ONU-MAC address).

[0060] To further illustrate, when it is necessary to determine the candidate resource slices corresponding to each downlink port of the first optical network unit, the resource slices can be matched according to the ONU-SN or ONU-MAC address of each downlink port, and identified as D-NetX (X=0,1,2,3,4,5,6,7,8).

[0061] Specifically, to determine whether D-NetX is suitable for the ONU, calculation and analysis are required based on two given conditions. These two conditions are:

[0062] (1) D-NetX-max (ONU) ≥ D-NetX-online (ONU).

[0063] (2) D-NetX-max(PON-Bandwidth)≥∑D-NetX-max(ONUx-Bandwidth) (where X=1,2,3,...,n).

[0064] The first condition ensures that the maximum bandwidth capability provided by the D-NetX network for the ONU (D-NetX-max (ONU)) is not less than the bandwidth currently required by the ONU online (D-NetX-online (ONU)). The second condition ensures that the maximum bandwidth capability provided by the D-NetX network for the entire PON (passive optical network) (D-NetX-max (PON-Bandwidth)) is not less than the sum of the maximum bandwidths required by all ONUs (ONU1, ONU2, ..., ONUn).

[0065] As an example, (1) collect data: obtain the value of D-NetX-max (ONU), obtain the value of D-NetX-online (ONU), obtain the value of D-NetX-max (ONUx-Bandwidth) of each ONU, calculate their sum, and obtain the value of D-NetX-max (PON-Bandwidth); (2) compare the first condition: check whether D-NetX-max (ONU) is greater than or equal to D-NetX-online (ONU); (3) compare the second condition: calculate the sum of the maximum bandwidth required by all ONUs: ∑D-NetX-max (ONUx-Bandwidth). Check whether D-NetX-max (PON-Bandwidth) is greater than or equal to this sum. (4) draw a conclusion: if both conditions are met, D-NetX is suitable for the ONU.

[0066] S202: Determine the first business slice corresponding to the terminal based on the business information corresponding to the terminal.

[0067] It should be noted that when it is necessary to determine the first business slice corresponding to the terminal, the business information corresponding to the terminal can be obtained in advance, and then compared one by one with at least one candidate business slice based on the business information. If the business content corresponding to a candidate business slice is the same as the business information, the candidate business slice will be used as the first business slice corresponding to the terminal.

[0068] The service information includes at least one of an identifier, a destination Internet Protocol address, a Point-to-Point Protocol over Ethernet (PPPoE), an Internet Protocol version 6 (IPv6), a priority field, a Transmission Control Protocol (TCP) source port, and a User Datagram Protocol (UDP) destination port;

[0069] The identifiers include a general encapsulation method port identifier GEMPortID, a logical link identifier LLID and a virtual local area network identifier VLANID.

[0070] Among them, the business slice is assigned to the business slice NSIY (Y=0,1,2,3,4,5,6,7,8) according to the logical identifier (LOID registration code, Password)

[0071] To further illustrate, there is a slice mapping relationship between resource slices and service slices, which is as follows: through resource slices, OLT virtualizes up to 8 slices as resource slices D-NetX (X=0,1,2,3,4,5,6,7,8); under each resource slice, ONU is assigned to up to 8 service slices NSIY (Y=0,1,2,3,4,5,6,7,8) according to the identifier. Example 1: Resource slice 1 (D-Net1) is divided into 3 service slices (NSI1, NSI2, NSI3); Example 2: Resource slice 2 (D-Net2) is divided into 2 service slices (NSI1, NSI2).

[0072] In one embodiment of the present application, it is necessary to determine the first service slice corresponding to the terminal, customize the priority of the service slice information, match one by one from the highest priority information, and mark NSIY (Y=0,1,2,3,4,5,6,7,8). In exceptional cases, if the service slice information cannot be matched, it is automatically assigned to the default slice NSI0.

[0073] S203: Determine slice information corresponding to the terminal according to the first resource slice and the first service slice.

[0074] It should be noted that after determining the first resource slice and the first business slice, the first resource slice and the first business slice are used as the slice information corresponding to the terminal.

[0075] In one embodiment of the present application, as shown in Figure 3, the ONU can report the physical identifier corresponding to its own resource information to the access network control system that executes slice determination through the OLT. After receiving the resource information, the slice configuration information module feeds back the resource information to the slice configuration matching module, so that the slice configuration matching module determines the first resource slice based on the resource information, and feeds back the first resource slice to the ONU through the OLT.

[0076] In one embodiment of the present application, as shown in Figure 4, the terminal can report its own service information to the access network control system that executes slice determination through the OLT. After receiving the service information, the slice configuration information module feeds back the service information to the slice configuration matching module, so that the slice configuration matching module determines the first service slice corresponding to the terminal according to the service information corresponding to the terminal, and feeds back the first service slice to the ONU through the OLT.

[0077] The above-mentioned slice determination method obtains the first resource slice of the first downlink port and the first service slice corresponding to the terminal; then, according to the first resource slice and the first service slice, the slice information corresponding to the terminal is determined. According to the above content, the present application determines the first resource slice and the first service slice by the actual resource situation of the optical network unit and the actual service situation corresponding to the terminal. Then, in the process of determining the slice information corresponding to the terminal according to the first resource slice and the first service slice, the resource slice and the service slice corresponding to the terminal are automatically allocated, the process of determining the first resource slice and the first service slice corresponding to the terminal is optimized, the portability of determining the slice information corresponding to the terminal is ensured, the service experience of industry customers is improved, the flexibility and intelligence of the industrial PON network are enhanced, the daily manual operation configuration of the industrial PON network is reduced, and the demand of industry users for the convenience of industrial PON network operation is met.

[0078] In one embodiment, as shown in FIG. 5 , when the terminal switches from accessing the first downlink port to accessing the second downlink port among the downlink ports of the first optical network unit, the following contents may be included:

[0079] S501: If the terminal switches from accessing the first downlink port to accessing the second downlink port among the downlink ports of the first optical network unit, a second resource slice corresponding to the second downlink port is obtained.

[0080] It should be noted that if the terminal switches from accessing the first downlink port to accessing the second downlink port among the downlink ports of the first optical network unit, the second resource slice of the second downlink port can be determined from the candidate resource slices corresponding to each downlink port based on the predetermined candidate resource slices corresponding to each downlink port of the first optical network unit.

[0081] Specifically, a storage unit that records candidate resource slices corresponding to each downlink port of the first optical network unit can be pre-set. When it is necessary to determine the second resource slice of the second downlink port, it can be searched in the storage unit according to the label of the second downlink port. If the downlink port label corresponding to a candidate resource slice is the same as the label of the second downlink port, the candidate resource slice will be used as the second resource slice of the second downlink port.

[0082] Among them, the second resource slice may be the same as or different from the first resource slice, and the second resource slice is not limited here.

[0083] S502: Update the slice information of the terminal according to the second resource slice.

[0084] It should be noted that before updating the slice information of the terminal according to the second resource slice, it can be verified whether the second resource slice is the same as the first resource slice. If they are not the same, the first resource slice in the slice information of the terminal is replaced with the second resource slice; if they are the same, there is no need to update the slice information of the terminal, or, when the slice information of the terminal carries the downlink port label of the first downlink port, the downlink port label of the first downlink port is replaced with the downlink port label of the second downlink port.

[0085] In one embodiment of the present application, as shown in Figure 6, if the terminal switches from accessing the first downlink port to accessing the second downlink port among the downlink ports of the first optical network unit, the second resource slice corresponding to the second downlink port is obtained; it is verified whether the second resource slice is the same as the first resource slice. If they are not the same, the first resource slice in the slice information of the terminal is replaced with the second resource slice. At this time, the slice information corresponding to the terminal is the second resource slice and the first service slice.

[0086] The above-mentioned slice determination method, when the terminal switches from accessing the first downlink port to accessing the second downlink port among the downlink ports of the first optical network unit, determines the second resource slice corresponding to the second downlink port to update the slice information of the terminal according to the second resource slice.

[0087] In one embodiment, as shown in FIG. 7 , when the terminal switches from accessing the first optical network unit to accessing the third downlink port of the second optical network unit, the following contents may be included:

[0088] S701: If the terminal switches from accessing the first optical network unit to accessing the third downlink port of the second optical network unit, obtain a third resource slice corresponding to the third downlink port.

[0089] It should be noted that if the terminal switches from accessing the first optical network unit to accessing the third downlink port of the second optical network unit, the third resource slice of the third downlink port can be determined from the candidate resource slices corresponding to each downlink port based on the predetermined candidate resource slices corresponding to each downlink port of the second optical network unit.

[0090] Specifically, a storage unit that records candidate resource slices corresponding to each downlink port of the second optical network unit can be pre-set. When the second resource slice of the third downlink port needs to be determined, it can be searched in the storage unit according to the label of the third downlink port. If the downlink port label corresponding to a candidate resource slice is the same as the label of the third downlink port, the candidate resource slice will be used as the third resource slice of the third downlink port.

[0091] Among them, the third resource slice may be the same as or different from the first resource slice, and the third resource slice is not limited here.

[0092] S702: Update the slice information of the terminal according to the third resource slice.

[0093] It should be noted that before updating the slice information of the terminal according to the third resource slice, it can be verified whether the third resource slice is the same as the first resource slice. If they are not the same, the first resource slice in the slice information of the terminal is replaced with the third resource slice; if they are the same, there is no need to update the slice information of the terminal, or, when the slice information of the terminal carries the downlink port label of the first downlink port, the downlink port label of the first downlink port is replaced with the downlink port label of the third downlink port.

[0094] In one embodiment of the present application, as shown in Figure 8, if the terminal switches from accessing the first optical network unit to accessing the third downlink port of the second optical network unit, the third resource slice corresponding to the third downlink port is obtained, and it is verified whether the third resource slice is the same as the first resource slice. If they are not the same, the first resource slice in the slice information of the terminal is replaced with the third resource slice. At this time, the slice information corresponding to the terminal is the third resource slice and the first service slice.

[0095] The above-mentioned slice determination method, when the terminal switches from accessing the first optical network unit to accessing the third downlink port of the second optical network unit, determines the third resource slice corresponding to the third downlink port to update the slice information of the terminal according to the third resource slice.

[0096] In one embodiment, as shown in FIG. 9 , when the service information corresponding to the terminal changes, the following contents may be included:

[0097] S901, verify whether the service information corresponding to the terminal has changed.

[0098] It should be noted that when it is necessary to verify whether the business information corresponding to the terminal has changed, a business information acquisition request can be sent to the terminal periodically, so that after receiving the business information acquisition request, the terminal can feedback the latest business information to the access network control system that executes the slice determination method. After receiving the latest business information, the access network control system compares the latest business information with the historical business information to see if they are the same. If they are different, it is determined that the business information corresponding to the terminal has changed; if they are the same, it is determined that the business information corresponding to the terminal has not changed.

[0099] Among them, the period of sending the service information acquisition request to the terminal can be set or adjusted according to the actual situation and the historical operation experience of the access network, and the period of sending the service information acquisition request to the terminal is not limited here.

[0100] Further explanation: if it is pre-specified that after the terminal is connected to the ONU, if the service information changes, it is necessary to actively send a service information change description to the access network control system that executes the slice determination method. Therefore, if the access network control system that executes the slice determination method receives the service information change description, it is determined that the service information corresponding to the terminal has changed; if the access network control system that executes the slice determination method does not receive the service information change description, it is determined that the service information corresponding to the terminal has not changed.

[0101] S902: If yes, determine the second business slice corresponding to the terminal based on the business information corresponding to the changed terminal.

[0102] It should be noted that when it is necessary to determine the second business slice corresponding to the terminal based on the business information corresponding to the changed terminal, the priority corresponding to each candidate business slice can be pre-set. According to this priority, each candidate business slice can be matched one by one with the business information corresponding to the changed terminal. The obtained candidate business slice that matches the business information corresponding to the changed terminal is the second business slice corresponding to the terminal.

[0103] S903: Update the slice information of the terminal according to the second business slice.

[0104] It should be noted that before updating the slice information of the terminal according to the second business slice, it can be verified whether the second business slice is the same as the first business slice. If they are not the same, the first business slice in the slice information of the terminal is replaced with the second business slice; if the slice information of the terminal before the update is the first resource slice and the first business slice, the slice information of the terminal after the update is the first resource slice and the second business slice.

[0105] The above-mentioned slice determination method, when the business information corresponding to the terminal changes, determines the second business slice corresponding to the terminal according to the changed business information corresponding to the terminal, and then updates the slice information of the terminal according to the second business slice, thereby ensuring the portability of determining the slice information corresponding to the terminal, improving the business experience of industry customers, enhancing the flexibility and intelligence of the industrial PON network, and reducing the daily manual operation configuration of the industrial PON network.

[0106] In one embodiment, as shown in FIG. 10 , when it is necessary to determine the resource slices corresponding to each downlink port of the first optical network unit, the following contents may be specifically included:

[0107] S1001, when a first optical network unit is connected to an access network control system, determining initial resource slices corresponding to each downlink port of the first optical network unit.

[0108] It should be noted that in order to ensure that the resource information corresponding to each downstream port of the first optical network unit can be successfully obtained in the future, the initial resource slices corresponding to each downstream port of the first optical network unit can be pre-specified when the first optical network unit is connected to the access network control system, so as to determine the initial resource slices corresponding to each downstream port of the first optical network unit when the first optical network unit is connected to the access network control system.

[0109] As shown in FIG. 11 , after the ONU goes online and accesses the access network control system, the initial resource slices corresponding to each downlink port of the first optical network unit are determined based on a pre-set access rule.

[0110] S1002: Acquire resource information corresponding to each downlink port of the first optical network unit according to initial resource slices corresponding to each downlink port of the first optical network unit.

[0111] The resource information includes at least one of an optical network unit supporting a maximum configuration or performance, an optical network unit in an online state or in real-time operation, a maximum bandwidth supported by a passive optical network PON, and a maximum bandwidth supported by an optical network unit.

[0112] S1003: Determine resource slices corresponding to each downlink port of the first optical network unit according to resource information corresponding to each downlink port of the first optical network unit.

[0113] It should be noted that when it is necessary to determine the resource slices corresponding to each downstream port of the first optical network unit, the priority corresponding to each candidate service slice can be pre-set. According to this priority, each candidate service slice can be matched one by one with the resource information corresponding to each downstream port of the first optical network unit. The obtained candidate service slices that match the resource information corresponding to each downstream port of the first optical network unit and the candidate service slices that match the resource information corresponding to each downstream port are the resource slices corresponding to each downstream port.

[0114] The above-mentioned slice determination method obtains the resource information corresponding to each downstream port of the first optical network unit according to the initial resource slices corresponding to each downstream port of the first optical network unit, and then determines the resource slices corresponding to each downstream port of the first optical network unit according to the resource information corresponding to each downstream port of the first optical network unit, thereby ensuring the portability of determining the slice information corresponding to the terminal, improving the business experience of industry customers, enhancing the flexibility and intelligence of the industrial PON network, reducing the daily manual operation configuration of the industrial PON network, and meeting the needs of industry users for convenient operation of the industrial PON network.

[0115] In an embodiment, as shown in FIG. 12 , when it is necessary to determine the slice information corresponding to the terminal, the following contents may be specifically included:

[0116] S1201: When a first optical network unit is connected to an access network control system, determine initial resource slices corresponding to each downlink port of the first optical network unit.

[0117] S1202: Acquire resource information corresponding to each downlink port of the first optical network unit according to initial resource slices corresponding to each downlink port of the first optical network unit.

[0118] S1203: Determine resource slices corresponding to each downlink port of the first optical network unit according to resource information corresponding to each downlink port of the first optical network unit.

[0119] S1204: When the terminal accesses a first downlink port among the downlink ports of the first optical network unit, obtain a first resource slice of the first downlink port.

[0120] S1205: Determine the first business slice corresponding to the terminal based on the business information corresponding to the terminal.

[0121] S1206: Determine the slice information corresponding to the terminal according to the first resource slice and the first service slice.
