Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
In order to clearly understand the technical solutions of the present application, the prior art solutions will be described in detail first. In the prior art, when an APP on a terminal needs to send a data packet, the terminal often cannot determine which network slice the APP data packet needs to use for transmission because the urs only define the mapping relationship between the APP ID and urs.
In order to solve the above problems, the inventors creatively found that a 5G module of a terminal can be improved, and a mapping relationship between a source IP of an APP being used on the terminal and a network slice is established, so that when the APP is transmitted, the terminal can determine a target network slice to transmit the APP packet according to the established mapping relationship between the source IP of the APP and the network slice, thereby solving the problem that the terminal in the prior art cannot determine which network slice is required to be used for transmitting the APP packet. If the target application program is to send the data packet, determining the data packet for transmitting the target application program based on the established mapping relation between the source IP of the target application program and the network slice.
The processing method for determining the network slice is suitable for the terminal APP communication scene. FIG. 1 is a schematic diagram of a processing system according to an embodiment of the present application. The processing system may include a core network and terminals, as well as base stations and other related components. The core network may be deployed with a plurality of network slices, when the terminal accesses the network, the core network issues a urs criterion to the terminal, specifically, the urs criterion may be defined by interaction between the base station and the terminal, the terminal receives the urs criterion, and may select and store, according to the self installed application APP, a mapping relationship between a network slice that may need to be accessed subsequently and an application identifier of each installed APP from the urs criterion, without storing the mapping relationship defined by the entire urs criterion. When an APP on a terminal is started, the terminal can acquire a source IP of the APP and an application program identifier corresponding to the APP, establish a mapping relation between the source IP of the APP and a network slice identifier, specifically can be a mapping relation between the source IP and the network slice identifier, when the APP has a data packet to be transmitted, the terminal can analyze the APP data packet to acquire the source IP corresponding to the data packet, and determine a target network slice for transmitting the data packet based on the source IP of the data packet and the mapping relation between the source IP and the network slice identifier, so that the data packet can be transmitted through the target network slice, and the terminal can effectively determine the target network slice required by the APP data packet based on the establishment of the mapping relation between the source IP of the APP and the network slice, thereby solving the problem that the terminal cannot determine which network slice is required to transmit the APP data packet in the prior art.
Alternatively, the mapping relationship between the network slice identifier and the application program identifier may be a one-to-one relationship, or may be a one-to-many relationship, that is, one network slice identifier may correspond to multiple application program identifiers. While the same application identity can only correspond to one network slice identity.
The interaction between the terminal and the core network and between the terminal and the base station are in the prior art, and the embodiments of the present application are not repeated.
Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. In the following description of the embodiments, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.
The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
An embodiment of the application provides a method for determining a network slice, which is used for determining a target network slice of an APP data packet transmitted by a terminal. The execution subject of the embodiment is a determination device of network slice, which may be provided in a terminal.
As shown in fig. 2, a flow chart of a method for determining a network slice according to the present embodiment is provided, where the method includes:
step 101, if the target application program has a data packet to be sent, acquiring the source IP of the target application program.
Specifically, when the target application program needs to send a data packet (called a data packet to be sent), the terminal needs to determine which network slice is used to transmit the data packet to be sent, and the terminal can analyze the data packet to be sent to obtain the source IP of the target application program to which the data packet to be sent belongs.
Step 102, determining a target network slice for transmitting the data packet to be transmitted according to the source IP of the target application program and a first mapping relation between the source IP of the target application program and the network slice identifier, which is established in advance.
Because the data flows of different application programs are different, namely the source IP and the destination IP are different, the mapping relation between the source IP and the network slice of each application program can be established, so that the terminal can accurately determine the corresponding target network slice according to the data packet of the application program.
The mapping relationship between the source IP of each application program and the network slice may be pre-established in the terminal, specifically, the mapping relationship between the source IP and the network slice identifier may be obtained from the mapping relationship, and the first mapping relationship between the source IP of the target application program and the network slice identifier may be obtained from the mapping relationship.
After the first mapping relation between the source IP of the target application program and the network slice identifier is obtained, a target network slice corresponding to the source IP of the target application program can be determined, and the target network slice can be used for transmitting the data packet to be transmitted of the target application program.
And step 103, transmitting the data packet to be transmitted through the target network slice.
After determining the target network slice for transmitting the data packet to be transmitted, the data packet to be transmitted can be transmitted through a slice path of the target network slice.
Alternatively, the terminal may pre-establish a slice path of each network slice that it may use, so that after determining the target network slice for transmitting the data packet to be transmitted, the data packet to be transmitted may be transmitted through the slice path of the target network slice. The terminal may also send a request for establishing a slice path to the core network after determining the target network slice for transmitting the data packet to be sent, if it is determined that the slice path of the target network slice is not established, the core network responds to the request for establishing the slice path of the terminal to establish the slice path of the target network slice, and the terminal may transmit the data packet to be sent through the slice path of the target network slice. Can be specifically set according to actual requirements.
According to the network slice determining method provided by the embodiment, the mapping relation between the APP source IP and the network slice is pre-established, so that when the APP has a data packet to be sent, the terminal can accurately determine the target network slice for transmitting the data packet, and therefore the data packet is transmitted through the target network slice, and the problem that the terminal cannot determine which network slice is required to transmit the APP data packet in the prior art is solved.
Another embodiment of the present application further supplements the method provided in the above embodiment.
As shown in fig. 3, an exemplary flowchart of a method for determining a network slice according to the present embodiment is shown.
As an implementation manner, on the basis of the foregoing embodiment, optionally, before determining, according to the source IP of the target application program and the first mapping relationship between the source IP of the target application program and the network slice identifier, the target network slice for transmitting the data packet to be sent, the method further includes:
in step 2011, the source IP of the target application and the target application identifier corresponding to the target application are obtained.
In step 2012, a first mapping relationship between the source IP of the target application program and the network slice identifier is established according to the source IP of the target application program, the target application program identifier, and a second mapping relationship between the pre-stored application program identifier and the network slice identifier.
Specifically, when a target APP (i.e., a target application program) in the terminal is started, the target APP may issue its source IP and an APP ID (i.e., a target application program identifier) corresponding to the target APP to a module corresponding to the terminal, and the terminal determines a network slice identifier corresponding to the target application program identifier according to a second mapping relationship between the pre-stored application program identifier and the network slice identifier, and establishes a mapping relationship between the source IP of the target application program and the network slice identifier according to the source IP of the target application program and the target application program identifier, so as to distinguish the first mapping relationship.
In an embodiment, optionally, the method may further include:
in step 2021, the urs criteria sent by the core network are received, where the urs criteria include a third mapping relationship between the application identity and the network slice identity.
Step 2022, selecting and storing a second mapping relationship between the application identifier of each installed application and its corresponding network slice identifier from the urs criteria according to the application identifier of the installed application.
Specifically, the core network may be deployed with a plurality of network slices, when the terminal accesses the network, the core network issues a urs criterion to the terminal, where the urs criterion defines a mapping relationship between a network slice and an application identifier (such as an APP ID), and in order to distinguish the third mapping relationship, the terminal receives the urs criterion, and may select, from the urs criterion, a mapping relationship (i.e. a second mapping relationship) between a network slice that may need to be accessed subsequently and an application identifier of each installed APP according to an APP installed by itself, and store the mapping relationship, without storing the third mapping relationship defined by the entire urs criterion, so that occupation of storage resources of the terminal may be reduced.
In the urs criteria, the mapping relationship between the network slice identifier and the application identifier may be a one-to-one relationship, or may be a one-to-many relationship, that is, one network slice identifier may correspond to multiple application identifiers. While the same application identity can only correspond to one network slice identity.
In an embodiment, optionally, the method may further include:
step 2031, updating the source IP of the target application program in the first mapping relationship to the changed source IP when the source IP of the target application program is changed; and when the target application program exits or is deleted, deleting the first mapping relation between the source IP of the target application program and the network slice identifier.
Specifically, when the source IP of the target application program changes, in order to avoid an error in the subsequent packet transmission of the target application program, the source IP in the first mapping relationship between the source IP of the target application program and the network slice identifier needs to be updated, and the source IP is updated to the changed source IP.
Optionally, the terminal may monitor, in real time or at a fixed time, whether the source IP of each application program changes, and update the mapping relationship between the source IP and the network slice identifier in time. Or the application program can timely send the changed source IP and the application program identification to the terminal when the source IP is changed, so that the terminal timely updates the mapping relation between the source IP and the network slice identification.
When the target application exits or deletes, the target application no longer uses the target network slice, so the first mapping relation between the source IP of the target application and the network slice identifier needs to be deleted, so that the target network slice can be used by other applications.
As another implementation manner, on the basis of the foregoing embodiment, optionally, before transmitting the data packet to be sent through the target network slice, the method further includes:
in step 2041, a slice path is established for the target network slice.
Specifically, the terminal may send a slice path establishment request to the core network, where the slice path establishment request may include a network slice identifier, such as a target network slice identifier, for establishing a slice path, and the core network returns a slice path establishment response in response to the slice path establishment request of the terminal, where the slice path establishment response includes relevant information of the target network slice, so that the terminal may use the slice path of the target network slice based on the relevant information. The specific slicing path establishment process is the prior art, and is not described herein.
In an embodiment, optionally, establishing a slice path for the target network slice includes:
step 2051, after receiving the urs criteria sent by the core network, establishing a slice path of the target network slice according to the installed application identifier and the urs criteria; or when the target network slice needs to transmit data, establishing a slice passage of the target network slice.
Specifically, the terminal may pre-establish a slice path of each network slice that may be used by the terminal, for example, after receiving the urs p criteria sent by the core network, and establish a slice path of the target network slice according to the installed application identifier and the urs p criteria, so that after determining the target network slice for transmitting the data packet to be transmitted, the data packet to be transmitted may be transmitted through the slice path of the target network slice.
The terminal may also send a request for establishing a slice path to the core network after determining the target network slice for transmitting the data packet to be sent, if it is determined that the slice path of the target network slice is not established, the core network responds to the request for establishing the slice path of the terminal to establish the slice path of the target network slice, and the terminal may transmit the data packet to be sent through the slice path of the target network slice. I.e. the slice path of the target network slice is re-established when the target network slice needs to transmit data. Can be specifically set according to actual requirements.
In an embodiment, optionally, the method may further include:
step 2061, closing a slice path of the target network slice when the terminal exits the network and/or the application corresponding to the target network slice is deleted or exits; or the slice passage idle time of the target network slice exceeds the preset time length, and the slice passage of the target network slice is closed.
Specifically, when the terminal exits the network, or when the application corresponding to the target network slice is deleted or exited, that is, the slice path of the target network slice is no longer needed, the slice path of the target network slice may be closed. It should be noted that, since there may be a case where a plurality of applications correspond to the same network slice, the slice path of the network slice is closed when all applications do not use the slice path of the network slice.
Alternatively, a timer may be started when the slice path of the target network slice enters an idle state, so as to record the idle time of the slice path of the target network slice, and when the idle time of the slice path of the target network slice exceeds a preset duration, the slice path of the target network slice is closed.
It should be noted that, in this embodiment, each of the possible embodiments may be implemented separately, or may be implemented in any combination without conflict, which is not limited to the implementation of the present application.
According to the method for determining the network slice, when the network slice needs to transmit data, the slice path is established again, so that occupation of resources is effectively reduced; and the occupation of resources is further reduced by closing the slicing passage of the network slice after the network slice is used up.
