The computer program may be integrated into the application or may run as a separate tool-like application.
Specifically, the method for establishing the data bearer includes:
s101: and when the application program is started, acquiring the access point identification APN of the application program.
Access Point Name (APN): it refers to a network access technology, which is a parameter that must be configured when a user accesses the internet through a terminal (e.g. a mobile phone). APNs are used to identify Data Networks (DNs), and different APNs correspond to different DNs, which may be defined by the operator. The APN determines which access method the terminal accesses to the network, and the range of the network and the access method of different APNs are different.
The processor of the terminal device 102 acquires the access point identifier APN of the application program when the application program is started. For example, the APN is an input string, which includes: ctnet [ nssai1:2 ]. Wherein, the segmentation character is: [] The input character string represents that the APN is: ctnet, slice identification information is: nssai1: 2; or the input character string includes: ctnet/nssai1:1, wherein the segmentation characters are: the input string indicates that the access point APN is: ctnet, slice identification information is: nssai1: 1; the radio interface layer of the terminal apparatus 102 acquires slice identification information from the input character string.
The Radio Interface Layer is an intermediate Layer in Android responsible for communication functions, and a Radio Interface Layer (RIL) may include two parts: RILJ and RILD, RILJ in the radio interface layer acquires an input character string from an upper layer. It is understood that RIL Java (RILJ): responsible for sending the communication request of the upper application to a Hardware Abstraction Layer (HAL); RIL C + + (RILD): the system daemon is responsible for sending request commands of RILJ to a Communication Processor (CP), which may be regarded as a HAL layer corresponding to the CP.
In a possible embodiment, the RILJ obtains the input character string from the upper layer, extracts the access point identification APN in the input character string, transmits the access point identification APN to the RILD, and transmits the access point identification APN to the modem by the RILD.
In another possible embodiment, the input string is obtained by RILJ from an upper layer, the input string is passed to the RILD, the access point identification APN in the input string is extracted by the RILD, and the access point identification APN is passed to the modem.
In one application implementation, the access point identifies the APN as an input string, and the user can set the APN of the terminal. For example, the steps that the user can set the APN of the terminal may be: a user receives an APN setting instruction of the application program; displaying an APN setting page of the application program based on the APN setting instruction; and responding to the input operation on the APN setting page, and acquiring an input character string.
The beneficial effects brought by the technical scheme provided by some embodiments of the application at least comprise: the input character string is appointed by a user and then acquired by the terminal equipment; the user is allowed to independently select the network slice and the data network accessed by the terminal equipment, the degree of freedom of the user for using the terminal equipment is improved, the user is supported to set according to the requirement, and private customization of data bearing is established when the terminal equipment and the network equipment are interacted.
In an embodiment of the application, the step of obtaining an input character string in response to an input operation on the APN setting page may include: displaying the APN setting interface; the APN setting interface comprises candidate options corresponding to the APN; in response to receiving a selection operation of a target option in the candidate options on the APN setting interface, determining the input character string corresponding to the target option. An APN setting interface may be understood as a user interface for setting an APN that allows a user to interact.
As shown in fig. 3, a schematic structural diagram of an APN setting interface provided in the embodiment of the present application includes at least one candidate option, and each candidate option corresponds to one candidate input character string. Such as: the candidate input character string corresponding to the candidate option "internet _ no _ NSSAI" is "internet"; the candidate input string corresponding to the candidate option "internet 2_ vdpg _ no _ NSSAI" is "internet 2"; the candidate input string corresponding to the candidate option "internet 2_ vEPG _ Slice _ 2" is "internet 2[ nssai1:2 ]". And the user selects from the candidate options, and the candidate option selected by the user is taken as a target option. It is understood that the candidate options within the selection range of the user are candidate options corresponding to the slice identification information. In the APN setting interface, an adding control of adding is also displayed. When the user does not want to select among the provided candidate options, the user may trigger an add control, which customizes the access point identifier APN, such as inputting: internet [ nssai1:3 ]. The application layer determines that the input string is "internet [ nssai1:3 ]. It is to be understood that, among others, the selection operation may be at least one of clicking, double-clicking, dragging, sliding, pressing, scanning, copying, pasting, and searching. The embodiment of the present application does not limit the specific type of the selection operation.
The beneficial effects brought by the technical scheme provided by some embodiments of the application at least comprise: determining an input character string based on the selection operation of the user in the candidate options, and then acquiring the input character string by the terminal equipment; the method allows a user to independently select the network slice and the data network accessed by the terminal equipment, improves the degree of freedom of the user for using the terminal equipment, supports the user to set according to the requirement, realizes the private customization of establishing data bearing when the terminal equipment and the network equipment are interacted, and meets the requirement of the user for independently selecting the network slice; and helping the user to adapt the APN and the corresponding network slice, reducing user operation and improving the efficiency of the terminal equipment for acquiring the APN.
S102, sending a data bearer establishment request message carrying APN to the network equipment.
The data bearer establishment request message may be understood as a request signaling for establishing a data bearer with the network device 101, which is a Radio Resource Control (RRC) signaling. The data bearer instruction requests the network device 101 to allocate a network slice corresponding to the APN carried in the data bearer request message, so as to hope to obtain a service corresponding to the network slice.
For example, a modem in terminal device 102 may initiate communication with network device 101, where the modem is configured to send a data bearer establishment request message, and the data bearer establishment request message carries an APN.
In an application embodiment, the data bearer establishment request message further carries network slice auxiliary Selection Information (NSSAI). Wherein the NSSAI may include two parts of a Slice Service Type (SST) and a Slice Differentiator (SD), the SST may include a standardized and operator-defined Type, and the SD is optional information that supplements the SST to differentiate multiple network slices of the same SST.
The beneficial effects brought by the technical scheme provided by some embodiments of the application at least comprise: the network slice auxiliary selection information assists the network equipment to select the network slice, and the data bearer is established with the terminal equipment based on the service and the network resource provided by the network slice, so that the efficiency of signaling communication is improved.
S103, receiving a data bearer establishment response message carrying the network slice identifier returned by the network equipment.
For example, the application "navigation" needs a network service of the low latency network, and based on the above steps, the low latency network (urlcc) network slice is allocated to the application "navigation", which may be understood as mapping the service data stream onto the data bearer corresponding to the low latency network (urlcc) network slice, and sending the mapped data stream to the network device 101.
And S104, establishing data bearing with the network equipment based on the network slice and the data bearing establishing response message.
The terminal device 102 establishes a data bearer with the network device 101, and the specified application 103 transmits a service data stream based on the data bearer.

In order to facilitate implementation of network resource isolation of a network slice of an access network, management of an end-to-end (E2E service) network slice based on a Qos flow is introduced in the embodiment of the present invention. The NG-RAN is a Radio access network based on next-generation cloud computing, the NG-CN is a core network based on next-generation cloud computing, and the NR (New Radio, New air interface) Node (base station) and the Radio Bearer refer to a Radio Bearer. In order to enable the network device 101 and the terminal device 102 to distinguish service data streams from different network slices to logically isolate corresponding wireless transmission resources or terminal processing resources, in the embodiment of the present invention, a network slice identifier is added to a service data stream according to a network slice corresponding to the service data stream at a core network side.
