For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. However, as will be appreciated by those of ordinary skill in the art, in the various embodiments of the present application, numerous technical details have been set forth in order to provide a better understanding of the present application. However, the technical solutions claimed in the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not be construed as limiting the specific implementation of the present application, and the embodiments may be mutually combined and referred to without contradiction.
Implementation details of the application-based slice selection method described in the present application will be specifically described below with reference to specific embodiments, and the following details are provided only for facilitating understanding, and are not necessary to implement the present embodiment.
A first aspect of the embodiments of the present application provides an application-based slice selection method, and specific flow of the application-based slice selection method refers to fig. 1, and in some embodiments, the application-based slice selection method is applied to gateway devices with WIFI access capability, such as home gateways facing end users, routers, and other electronic devices, where the application is illustrated in the home gateways, and the slice selection method at least includes, but is not limited to, the following steps:
step 101, obtaining the corresponding relation between the application and the slice from the network side, and mapping each slice corresponding to each application to different service set identifiers SSID to obtain the corresponding relation between the application and the SSID.
Specifically, after the home gateway finishes deployment and starts to be used, based on the support of network slices, the home gateway interacts with the 3GPP core network through a preset communication protocol, obtains the corresponding relation between a plurality of applications and the created slices with different service qualities from the core network, maps each slice corresponding to each application onto different service set identification SSID according to the obtained corresponding relation between the applications and the slices, obtains the corresponding relation between the different applications and the different service set identification SSID in the home gateway, and stores the obtained corresponding relation in a storage module of the home gateway or a storage address capable of communicating with the home gateway.
In one example, before mapping each slice corresponding to each application to a different service set identification SSID, the home gateway further includes: establishing a plurality of slices; establishing a plurality of SSIDs under the condition that the establishment of the plurality of slices is successful; when the SSID is successfully established, mapping each slice corresponding to each application to a different service set identification SSID is executed.
Specifically, after the home gateway starts to be used, according to function support provided as required or a received instruction, based on the support of network slices, interacting with the 3GPP core network, obtaining configuration information corresponding to a plurality of slices to be created, and then creating a plurality of slice functions corresponding to different service qualities on the home gateway according to the configuration information corresponding to each slice. After the home gateway completes the creation of the plurality of slices, whether the creation of the plurality of slices is successful or not can be detected, under the condition that the creation failure slices exist, the signing condition of equipment, the supporting condition of the current network, the equipment state of the home gateway and the like can be detected, new configuration information is re-requested according to the detection result, the re-creation of the slices with the creation failure is completed, and the creation of all the slices with the creation failure is successfully completed.
After the creation of the plurality of slices with different service qualities is successful, the home gateway starts the SSID function supported by the home gateway, and creates a plurality of service set identification SSIDs inside the home gateway, wherein the number supported by the service set identification SSID can be determined according to supportable data of the home gateway and the number of the slices created in advance. After the creation of the service set identifiers SSID is completed, whether the service set identifiers SSID are created successfully or not can be detected, and the service set identifiers SSID are re-created until the successful creation of all the service set identifiers SSID is completed under the condition that the service set identifiers SSID with the failed storage creation or illegal parameters are detected. And then the home gateway establishes a mapping relation between the created slice and the service set identification SSID. Namely, corresponding SSIDs are allocated to different slices, and the corresponding relation between each slice and the service set identification SSID is stored in a designated storage address or device, so that the subsequent call is facilitated. After a plurality of different slice functions are established according to the possible needs of the terminal equipment, a plurality of service set identification SSIDs and mapping relations between the service set identification SSIDs and the slices are created and stored, so that the corresponding relation between the application and the service set identification SSIDs can be determined according to the mapping relations between the slices and the service set identification SSIDs, and the efficiency of the home gateway for realizing the slice selection function is improved.
In another example, the home gateway maps each slice corresponding to each application to a different service set identification SSID, respectively, including: and configuring independent routes for the network ports of the SSIDs according to the slices corresponding to the applications. Specifically, when the home gateway maps each slice to a different service set identifier SSID, according to the corresponding relation between the slice and the service set identifier SSID and the application, the home gateway obtains route configuration information of the network port corresponding to each service set identifier SSID, and according to the obtained route configuration information, the home gateway performs independent route configuration on the network port corresponding to each service set identifier SSID. By the corresponding relation of the slices to the service set identification SSID and the application respectively, the independent route configuration is accurately completed for the network ports corresponding to the service set identification SSID, so that the terminal equipment can accurately call the corresponding slicing functions according to the designated network ports.
Step 102, the corresponding relation between the application and the SSID is sent to the terminal equipment, so that the terminal equipment can communicate with the gateway equipment based on the SSID corresponding to the currently started application.
Specifically, after receiving a dynamic host configuration request of the terminal device, the home gateway carries a corresponding relation between an application and a service set identifier SSID which are acquired and stored in advance in a response message and sends the response message to the terminal device, so that the terminal device determines the service set identifier SSID corresponding to the currently started application, and calls a slice corresponding to the service set identifier SSID through a designated network port to communicate with the gateway device based on the service set identifier SSID corresponding to the currently started application. By issuing the corresponding relation between the application and the service set identifier SSID to the terminal equipment, the terminal can select a designated network port to call a slice corresponding to the service set identifier SSID to communicate with the gateway equipment according to the service set identifier SSID corresponding to the currently started application, and the network slice selection is indirectly realized by using the corresponding relation between the application and the service set identifier SSID.
In one example, the home gateway sends the correspondence between the application and the SSID to the terminal equipment, including: after receiving a Dynamic Host Configuration Protocol (DHCP) process initiated by the terminal equipment, carrying the corresponding relation between the application and the SSID in a custom extension field of a DHCP response message, and sending the corresponding relation between the application and the SSID to the terminal equipment. Specifically, the communication protocol of dynamic host configuration protocol DHCP is adopted between the home gateway and the terminal equipment, and when the terminal equipment needs to communicate with the home gateway, a dynamic host configuration request is initiated to the home gateway based on the DHCP. After receiving a dynamic host configuration request of the terminal equipment, the home gateway reads the corresponding relation between the prestored application and the service set identifier SSID, and encapsulates the corresponding relation information between the application and the slice/SSID in a custom expansion field of a response message based on DHCP. And feeding back a DHCP response message carrying the corresponding relation between the application and the service set identification SSID to the terminal equipment, so that the terminal equipment can analyze the acquired DHCP response message to acquire the corresponding relation between the application and the service set identification SSID, and calling a slice corresponding to the service set identification SSID through a designated network port to communicate with the gateway equipment according to the service set identification SSID corresponding to the current application. By carrying the corresponding relation between the application and the service set identifier SSID in the expanding field of the DHCP response, the corresponding relation is issued based on the existing protocol so as to realize the slice selection function in the wireless routing scene, thereby avoiding the need of providing new configuration or function requirements for gateway equipment, reducing the implementation cost and improving the application prospect.
For ease of understanding, the slice selection process is described below in connection with practical examples. Under the current wireless routing scene, the home gateway has two service set identifiers SSID, the communication terminal has only two applications, namely GAME APP (glass of Kings) and common APP (Toutao), the home gateway creates two slices in advance, namely a 5G network common slice and a 5G network GAME slice, SSID (service set identifier) and ZTE (service set identifier) are configured to correspond to the 5G network common slice and the 5G network GAME slice respectively, and a routing corresponding relation between the SSID and the slices is established through a routing table. And according to the corresponding relation between the application and the slice, the corresponding relation between the application and the SSID is determined and stored. Namely, the "glass of Kings" corresponds to ZTE_SSID_GAME; all other applications correspond to zte_ssid_normal.
When the terminal accesses the home gateway and initiates a DHCP process, the corresponding relation between the application and the SSID is encapsulated in an expansion field of the DHCP response message, and after the communication terminal receives the DHCP response message, the communication terminal defaults to connect 'ZTE_SSID_NORMAL', and carries out communication service based on the SSID.
When the user runs APP "toutia" on the communication terminal, since the application does not configure SSID alone, communication is continued using default "zte_ssid_normal", and the data flow at this time is: toutao < - > "ZTE_SSID_NORMAL" < - > "5G network NORMAL slice". After a period Of time, the user runs "Gloary Of Kings" on the communication terminal, and when the APP is started, because the application is configured with the SSID alone, according to the mapping relationship between the SSID and the slice, the designated slice corresponding to the connection APP, that is, "zte_ssid_game", is triggered. The APP will bind to the "network port" to which the SSID corresponds (e.g., may be implemented by the so_BINDTODEVICE of socket on a Linux-like operating system). The data flow at this time is: "Gloary Of Kings" < - > "ZTE_SSID_GAME" < - > "5G network GAME slice".
When the communication terminal does not support multiple Wi-Fi connections, after the game application is started, the communication terminal automatically disconnects zte_ssid_normal of default connection, and when the communication terminal supports multiple Wi-Fi connections, the communication terminal can maintain previous connection.
After a period of time, the user exits from the category of Kings. When the APP exits, the communication terminal checks that the router issues slice/SSID information, triggers the flow of disconnecting the specific slice 'ZTE_SSID_GAME', and automatically disconnects the connection with the 5G GAME slice.
Another aspect of the embodiments of the present application further provides an application-based slice selection method, and the application-based slice selection method specifically refers to fig. 2, and in some embodiments, the application-based slice selection method is applied to a terminal accessing gateway devices through WIFI, for example, electronic devices such as a mobile phone, a computer, and a digital television, where the application is illustrated by taking the mobile phone as an example, and the slice selection method at least includes, but is not limited to, the following steps:
step 201, obtaining a corresponding relation between an application and a service set identifier SSID from a gateway device.
Specifically, in the wireless routing scenario, before the mobile phone performs data communication interaction, the mobile phone accesses to the home gateway or the wireless router in a WIFI access mode, and before the application is started, a dynamic host configuration request is initiated to the home gateway or the wireless router to request to acquire an IP address of a dynamic host configured in the data traffic process, and the corresponding relation between the application to be started and the service set identifier is acquired from gateway equipment.
In one example, the mobile phone obtains a correspondence between an application and a service set identifier SSID from a gateway device, including: after initiating a Dynamic Host Configuration Protocol (DHCP) process to gateway equipment, receiving a DHCP response message fed back by the gateway equipment; the user-defined extension field of the DHCP response message carries the corresponding relation between the application and the SSID; and obtaining the corresponding relation between the application and the SSID by analyzing the custom extension field of the DHCP response message. Specifically, after the mobile phone accesses the home gateway or the wireless router in a WIFI connection mode, a dynamic host configuration request is initiated to the connected gateway equipment based on a dynamic host configuration protocol DHCP, and then a DHCP response message issued by the gateway equipment is received. Analyzing the custom expansion field in the received DCHP response message, acquiring the corresponding relation between the application encapsulated in the custom expansion field and the SSID, and storing the corresponding relation in a storage module of the self. The application and SSID corresponding relation is packaged and transmitted by utilizing the expansion field of the existing protocol, so that the terminal can directly acquire the application and SSID corresponding relation based on the existing protocol, further acquire the application and slice corresponding relation, and the network slice selection function of the terminal equipment based on the APP is simply and efficiently realized in a wireless routing scene.
Step 202, after the application is started, querying the SSID corresponding to the currently started application in the correspondence between the application and the SSID. Specifically, after detecting that a user starts one of the applications in the mobile phone, the mobile phone reads the corresponding relation between the application stored in the mobile phone and the SSID, detects whether the SSID corresponding to the current starting application is prestored, and further determines a network port for communicating with the gateway equipment.
In one example, after querying an SSID corresponding to a currently started application, the mobile phone communicates with the gateway device based on a preset SSID if the corresponding SSID is not queried. Specifically, when the mobile phone fails to acquire the SSID corresponding to the currently started application, the SSID corresponding to the currently started application is determined to be a preset default SSID, and a designated network port is selected to communicate with the gateway device directly based on the preset default SSID. By presetting a default SSID which cannot be used when a corresponding SSID can not be queried, interference to data communication of an application with a preset SSID is avoided in the starting process of a new application or an application without the preset specific SSID.
In step 203, in the case that the corresponding SSID is queried, communication is performed with the gateway device based on the corresponding SSID.
Specifically, when the mobile phone has queried the SSID corresponding to the currently started application, according to the queried network port corresponding to the SSID, invoking the slice corresponding to the SSID to communicate with the gateway device, and indirectly realizing the network slice selection by utilizing the corresponding relation between the application and the SSID.
