All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
For a clear understanding of the technical solutions of the present application, a detailed description of the prior art solutions is first provided. In the prior art, when a certain APP on a terminal has a data packet to send, since the URSP only defines the mapping relationship between the APP ID and the URSP, the terminal often cannot determine which network slice the APP data packet needs to be transmitted by.
In view of the above problems in the prior art, the inventors have conducted creative research and found in research, where in the prior art, a terminal cannot determine which network slice the APP data packet needs to be transmitted according to a mapping relationship defined by a URSP, and in order to solve the above problems, the inventors creatively found that a 5G module of the 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 an APP has a data packet for transmission, the terminal can determine a target network slice to transmit the data packet of the APP according to the established mapping relationship between the source IP of the APP and the network slice, thereby solving a problem that in the prior art, the terminal cannot determine which network slice the APP data packet needs to be transmitted, and therefore an embodiment of the present application provides a processing method for determining a network slice, which specifically includes: and if the target application program has a data packet to be sent, 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 APP communication scene of the terminal. Fig. 1 is a schematic diagram of an architecture of a processing system according to an embodiment of the present application. The processing system may include a core network and a terminal, and may also include a base station 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 URSP criterion to the terminal, specifically, the URSP criterion may be interaction with the terminal through a base station, the URSP criterion defines a mapping relationship between a network slice and an application identifier (such as APP ID), and when the terminal receives the URSP criterion, the terminal may select, according to an installed application APP, a mapping relationship between a network slice that may need to be accessed subsequently and the application identifier of each installed APP from the URSP criterion and store the mapping relationship, without storing the mapping relationship defined by the entire URSP criterion. When a certain 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, a mapping relation between the source IP of the APP and a network slice is established, specifically, the mapping relation between the source IP and the network slice identifier can be established, when a data packet of the APP needs to be transmitted, the terminal can analyze the APP data packet, a source IP corresponding to the data packet is obtained, a target network slice for transmitting the data packet is determined 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, based on the establishment of the mapping relation between the source IP of the APP and the network slice, the terminal can effectively determine the target network slice needed by the APP data packet, and the problem that the terminal cannot determine which network slice the APP data packet needs to be transmitted through in the prior art is solved.
Optionally, the mapping relationship between the network slice identifier and the application identifier may be a one-to-one relationship or a one-to-many relationship, that is, one network slice identifier may correspond to multiple application identifiers. And the same application id can only correspond to one network slice id.
The interaction between the terminal and the core network and the base station is the prior art, and the embodiment of the present application is not described again.
Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the following examples, "plurality" means two or more unless specifically limited otherwise.
The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
An embodiment of the present application provides a method for determining a network slice, which is used for determining a target network slice for a terminal to transmit an APP data packet. The execution subject of the present embodiment is a determination device of a network slice, which may be provided in a terminal.
As shown in fig. 2, a schematic flow chart of a method for determining a network slice provided in this embodiment is shown, where the method includes:
Specifically, the target application is an application installed on the terminal, and when the target application needs to send a data packet (called a to-be-sent data packet), the terminal needs to determine through which network slice the to-be-sent data packet needs to be transmitted, and the terminal can analyze the to-be-sent data packet to obtain a source IP of the target application to which the to-be-sent data packet belongs.
Because the data streams 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, specifically, the mapping relationship between the source IP and the network slice identifier, may be pre-established in the terminal, 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 relationship 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 may be determined, and the target network slice may be used to transmit a to-be-transmitted data packet of the target application program.
And 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 the slice channel of the target network slice.
Optionally, the terminal may pre-establish a slicing path of each network slice that may be used by the terminal, so that after a target network slice for transmitting a data packet to be transmitted is determined, the data packet to be transmitted may be transmitted through the slicing path of the target network slice. The terminal may also be configured to send a slicing path establishment request to the core network if it is determined that a slicing path of the target network slice is not established after determining the target network slice for transmitting the data packet to be transmitted, where the core network responds to the slicing path establishment request of the terminal to establish the slicing path of the target network slice, and the terminal may transmit the data packet to be transmitted through the slicing path of the target network slice. The method can be specifically set according to actual requirements.
According to the method for determining the network slice, 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, the data packet is transmitted through the target network slice, and the problem that the terminal cannot determine which network slice the APP data packet needs to be transmitted through in the prior art is solved.
The method provided by the above embodiment is further described in an additional embodiment of the present application.
As shown in fig. 3, an exemplary flowchart of the method for determining a network slice provided in this embodiment is shown.
As an implementable manner, on the basis of the foregoing embodiment, optionally before determining the target network slice for transmitting the data packet to be transmitted according to the source IP of the target application and the pre-established first mapping relationship between the source IP of the target application and the network slice identifier, the method further includes:
in step 2011, the source IP of the target application and the target application id corresponding to the target application are obtained.
Specifically, when a target APP (i.e., a target application) in a terminal is started, the target APP may issue a source IP of the target APP and an APP ID (i.e., a target application identifier) corresponding to the source IP to a module corresponding to the terminal, the terminal determines a network slice identifier corresponding to the target application identifier according to a second mapping relationship between a pre-stored application identifier and the network slice identifier, and establishes a mapping relationship between the source IP of the target application and the network slice identifier according to the source IP of the target application and the target application identifier, which is referred to as a first mapping relationship for differentiation.
In an embodiment, optionally, the method may further include:
Specifically, the core network may be deployed with a plurality of network slices, when the terminal accesses the network, the core network issues a URSP criterion to the terminal, where the URSP criterion defines a mapping relationship between a network slice and an application identifier (for example, APP ID), and in order to distinguish the mapping relationship from a third mapping relationship, the terminal receives the URSP criterion, and may select, according to an installed application APP, a mapping relationship (i.e., a second mapping relationship) between a network slice that may need to be accessed subsequently and the application identifier of each installed APP from the URSP criterion and store the mapping relationship, without storing the third mapping relationship defined by the entire URSP criterion, so that the occupation of terminal storage resources may be reduced.
In the URSP criterion, the mapping relationship between the network slice identifier and the application program identifier may be a one-to-one relationship or a one-to-many relationship, that is, one network slice identifier may correspond to multiple application program identifiers. And the same application id can only correspond to one network slice id.
In an embodiment, optionally, the method may further include:
step 2031, when the source IP of the target application program changes, updating the source IP of the target application program in the first mapping relationship to the changed source IP; 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 is changed, in order to avoid a subsequent error in packet transmission of the target application, the source IP of the target application and the source IP in the first mapping relationship of the network slice identifier need to be updated, and the source IP is updated to the changed source IP.
Optionally, the terminal may monitor whether the source IP of each application program changes in real time or at regular time, and update the mapping relationship between the source IP and the network slice identifier in real time. Or the application program sends the changed source IP and the application program identifier to the terminal in time when the source IP is changed, so that the terminal updates the mapping relationship between the source IP and the network slice identifier in time.
When the target application program exits or is deleted, the target application program no longer uses the target network slice, and therefore, the first mapping relationship between the source IP of the target application program and the network slice identifier needs to be deleted, so that the target network slice can be continuously used by other application programs.
As another practicable manner, on the basis of the foregoing embodiment, optionally, before transmitting the data packet to be transmitted through the target network slice, the method further includes:
step 2041, a slicing path of the target network slice is established.
Specifically, the terminal may send a slicing path establishment request to the core network, where the slicing path establishment request may include a network slice identifier, such as a target network slice identifier, for establishing a slicing path, and the core network returns a slicing path establishment response including information related to the target network slice in response to the slicing path establishment request of the terminal, so that the terminal may use the slicing path of the target network slice based on the related information. The specific slicing path establishment process is the prior art and is not described herein again.
In one embodiment, optionally, establishing a slice path of the target network slice includes:
step 2051, after receiving the URSP criteria sent by the core network, establishing a slice path of the target network slice according to the installed application program identifier and the URSP criteria; or when the target network slice needs to transmit data, establishing a slice path of the target network slice.
Specifically, the terminal may pre-establish a slicing path of each network slice that the terminal may use, for example, after receiving a URSP criterion sent by the core network, establish a slicing path of a target network slice according to an installed application identifier and the URSP criterion, so that after determining the target network slice for transmitting a data packet to be transmitted, the terminal may transmit the data packet to be transmitted through the slicing path of the target network slice.
The terminal may also be configured to send a slicing path establishment request to the core network if it is determined that a slicing path of the target network slice is not established after determining the target network slice for transmitting the data packet to be transmitted, where the core network responds to the slicing path establishment request of the terminal to establish the slicing path of the target network slice, and the terminal may transmit the data packet to be transmitted through the slicing path of the target network slice. I.e. when the target network slice needs to transmit data, the slice path of the target network slice is established again. The method can be specifically set according to actual requirements.
In an embodiment, optionally, the method may further include:
step 2061, when the terminal exits the network and/or the application program corresponding to the target network slice is deleted or exited, closing the slice passage of the target network slice; or the slice access idle time of the target network slice exceeds the preset time length, and the slice access of the target network slice is closed.
Specifically, when the terminal exits the network, or the application corresponding to the target network slice is deleted or exited, that is, when 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 multiple applications correspond to the same network slice, the slice path of the network slice is closed only when all the applications do not use the slice path of the network slice.
Optionally, a timer may be started when the slicing path of the target network slice enters an idle state, and is used to record idle time of the slicing path of the target network slice, and when the slicing path idle time of the target network slice exceeds a preset time, the slicing path of the target network slice is closed.
It should be noted that the respective implementable modes in the present embodiment may be implemented individually, or may be implemented in combination in any combination without conflict, and the present application is not limited thereto.
According to the method for determining the network slice, the slice path is established when the network slice needs to transmit data, so that the occupation of resources is effectively reduced; and the slice access is closed after the network slice is used up, so that the occupation of resources is further reduced.
