The definitions or explanations of the concepts and terms referred to in this application are as follows.

The APP refers to various applications installed on the device, such as a shopping application, a communication application, and the like.

Protocol Data Unit (PDU) refers to a Unit of Data transferred between peer layers. The PDU of the physical layer is data bits (bit), the PDU of the data link layer is data frames (frame), the PDU of the network layer is data packets (packet), the PDU of the transport layer is data segments (segment), and the other higher layer PDUs are data (data).

The PDU Session is a granularity unit of a network slice in the fifth generation 5G mobile communication system.

The network slice is a networking mode according to needs, an operator can separate a plurality of virtual end-to-end networks on a unified infrastructure, and each network slice is logically isolated from a wireless access network bearing network to a core network so as to adapt to various types of applications. In one network slice, at least three parts of a wireless network sub-slice, a bearer network sub-slice and a core network sub-slice can be divided.

The UE Route Selection Policy (URSP) is one of Policy information provided by the 5G core network 5GC from a Policy Control Function entity (PCF) to a User Equipment (UE). The UE uses this policy to determine how to route the data outbound path. The UE may determine, via the URSP rule, whether the detected application may be associated with an already established PDU session or whether a new PDU session may be established. An important input datum in the URSP rule is a parameter in a Traffic Descriptor (TD), which may be carried by an application when initiating a network request.

The technical solution of the embodiment of the present application may be applied to the example communication system 100 shown in fig. 1A, where the example communication system 100 includes a terminal 110 and a network device 120, and the terminal 110 is communicatively connected to the network device 120.

How to select a routing path for an application is not explicitly agreed at present.

In view of the foregoing problems, an embodiment of the present application provides a method for establishing a protocol data unit session, which is described in detail below with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a flowchart illustrating a method for establishing a pdu session according to an embodiment of the present application, where the method includes s201 to s 204, where:

s201, the terminal creates a first application scene where the target application program APP is currently located.

The target APP may be a system application or a third-party application installed in advance in the terminal, the target APP may be a communication APP, such as WeChat, QQ, strange, spy, and the like, the target APP may be a video APP, such as tremble, fast hand, watermelon video, and the like, and the target APP may also be a game APP, such as Royal, King, Anken: large fleets & bugs, & ltpeace and elite ], etc., the target APP may also be other types of APPs, not limited herein.

In one possible example, the terminal creates a first application scenario in which the target application APP is currently located, including: the terminal acquires state information of the target APP, wherein the state information is used for reflecting the current state of the target APP; and the terminal creates the current application scene of the target APP according to the state information.

In this possible example, the status information includes at least one of a use place, a use time, and a type.

Optionally, the state information includes the use location, and the terminal creates an application scenario where the target APP is currently located according to the state information, including: and the terminal creates the current application scene of the target APP according to the using place.

The application scene where the terminal creates the application program according to the use place may be the application scene where the terminal creates the application program according to the kind of the use place. For example, if the use location is at home, the current application scenario of the target APP is an application scenario at home, if the use location is at office, the current application scenario of the target APP is an application scenario at office, and if the use location is at restaurant, the current application scenario of the target APP is an application scenario at restaurant, and other types of use locations may also be included, which is not specifically limited.

The application scene where the application program is currently located can be created by the terminal according to the use place, or the corresponding application scene can be created by the terminal according to the specific name of the use place. For example, if the usage location is at a, the current application scene of the target APP is at a, and if the usage location is at B, the current application scene of the target APP is at B, which is not specifically limited.

Optionally, the state information includes the use location and the type, and the terminal creates an application scenario where the target APP is currently located according to the state information, including: and the terminal creates an application scene where the target APP is currently located according to the using place and the type.

The creating, by the terminal, the current application scenario of the target APP according to the usage location and the type may be that the terminal creates the current application scenario of the target APP according to the type of the usage location and the type of the target APP. For example, if the use location is at home and the target APP is a game APP, the current application scene of the target APP is a game playing application scene at home, if the use location is at office and the target APP is a shopping APP, the current application scene of the target APP is a business shopping application scene at business office, if the use location is at restaurant and the target APP is a communication APP, the current application scene of the target APP is a social software application scene at restaurant, and the like, without specific limitation.

The creating, by the terminal, the application scene where the target APP is currently located according to the use location and the type may be that the terminal creates the application scene where the target APP is currently located according to the specific name of the use location and the type of the target APP. For example, if the usage location is a and the target APP is a shopping APP, the current application scenario of the target APP is an online shopping application scenario at a, and if the usage location is a B and the target APP is a communication APP, the current application scenario of the target APP is a social software application scenario played at B, and the like, which are not specifically limited.

Optionally, the state information includes the usage time, and the terminal creates an application scenario where the target APP is currently located according to the state information, including: and the terminal creates the current application scene of the target APP according to the use time.

For example, if the use time is weekday afternoon, the application scene where the target APP is currently located is a weekday afternoon a-period application scene, where the a-period includes the weekday afternoon, and if the use time is monday afternoon five-hour, the application scene where the target APP is currently located is a monday afternoon B-period application scene, and so on, it should be noted that the time period may be determined according to the use habit of the user, and then, different time periods in the time period are partitioned without specific limitation.

Optionally, the state information includes the use location, the use time, and the type, and the terminal creates an application scenario where the target APP is currently located according to the state information, including: and the terminal creates an application scene where the target APP is currently located according to the using place, the using time and the type.

The terminal creating the current application scenario of the target APP according to the usage location, the usage time, and the type includes the terminal creating the current application scenario of the target APP according to the type or specific name of the usage location, the usage time, and the type of the target APP, and is not particularly limited. For example, if the current location of the terminal is a company, the time is 6 pm on a weekday, and the type of the target APP is a game APP, the first application scenario may be a game application scenario played at the company at 6 pm on the weekday.

It should be noted that the application scenario of the target APP may also be created in other ways, which is not limited in particular.

And s202, the terminal queries an application program APP identity Identification (ID) set according to the first application scene to obtain a first APP ID of the target APP corresponding to the first application scene, wherein the APP ID set comprises a corresponding relation between the application scene and an APPID.

The APP ID specifically refers to identification information corresponding to the APP and the application scenario, and is used to indicate the current application scenario of the APP.

The following describes this section in detail by taking the first way of creating an application scene for an application program as an example:

for example, when the APP is at home, the APP ID allocated to the APP is APP1, when the APP is at office, the APP ID allocated to the APP is APP2, and when the APP is at restaurant, the APP ID allocated to the APP is APP 3.

The specific representation form of the APP ID set may be various, and is not limited herein.

For example, the APP ID set may be an APP ID configuration file, and the correspondence between APP n and the corresponding application scenario may be:

{ at home, APP1}, { at office, APP2}, and { APP3, at restaurant }.

As another example, the APP ID set may be as shown in table 1:

TABLE 1

Application scenarios	APP ID
		At home	APP1
In an office	APP2
		In a restaurant	APP3

It should be noted that the APP ID set is only an example, and the correspondence between the application scenario and the APP ID is not specifically limited.

And s 203, the terminal queries a URSP selection set of a user equipment routing strategy according to the first APP ID to obtain a first URSP of the target APP corresponding to the first APP ID, wherein the URSP selection set comprises a corresponding relation between the URSP and an APPID.

In a specific implementation, it is preset that the URSP1 is a URSP signed with a telecom operator, the URSP2 is a URSP signed with a unicom operator, and the URSP3 is a URSP signed with a mobile operator.

The correspondence between the URSP and the APP ID is obtained by the terminal through URSP selection statistics of APPs of different scenes in the local historical data, for example, if the APP ID of the APP is APP1, the frequency of the URSP selected by the APP is highest as URSP1, then APP1 corresponds to the URSP1, if the APP ID of the APP is APP2, the frequency of the URSP selected by the APP is highest as URSP2, then APP2 corresponds to the URSP2, if the APP ID of the APP is APP3, the frequency of the URSP selected by the APP is highest as URSP3, then APP3 corresponds to the URSP 3.

For example, the URSP selection set may be a URSP configuration file, and the correspondence between APP n and ursn may be expressed as:

{APP1，URSP1}，{APP2，URSP2},{APP3，URSP3}。

as another example, the URSP selection set may be as shown in table 2:

TABLE 2

APP ID	URSP
		APP1	URSP1
APP2	URSP2
		APP3	URSP3

It should be noted that the above URSP selection set is only an example, the correspondence between APP ID and URSP is not specifically limited, and the URSP may also include a URSP registered by the target APP and another operator.

And s 204, the terminal determines a first Protocol Data Unit (PDU) Session of the target APP according to the first URSP.

Wherein, the determining, by the terminal, a first protocol data unit PDU Session of the target APP according to the first URSP includes: the terminal determines whether a PDUSESION matched with the first APP ID exists or not according to the URSP; if so, determining the matched PDU Session as the first PDU Session; if not, establishing the first PDU Session for the currently processed APP according to the first URSP.

In the concrete implementation, if a PDU Session created by the terminal for the application program exists in the PDU sessions that match the application scene where the application program is currently located, the PDU Session does not need to be created, and the matched PDU Session is directly used as a target object, and if the PDU Session created by the terminal for the application program does not exist in the PDU Session that matches the application scene where the application program is currently located, the PDU Session needs to be created, and the created PDU Session is used as the target object.

In one possible example, the method further comprises: after successfully determining a PDU Session for a currently processed APP, the terminal acquires an application scene established in the PDU Session determining process, an allocated APP ID and a matched URSP; the terminal determines the APP ID set according to the application scene established in the PDU Session determining process and the allocated APP ID; and the terminal determines the URSP selection set according to the APP ID distributed in the PDU Session determining process and the matched URSP.

The currently processed APP may be one of all APPs installed in the local device and scanned by the terminal.

The creating process of the application scenario established in the process of determining the PDU Session is consistent with the selection manner of s201 in fig. 2, please refer to the description of s201 in fig. 2, and details are not repeated here.

The implementation manner of determining the APP ID set by the terminal according to the application scenario established in the PDU Session determining process and the allocated APP ID may be: the terminal judges whether the APP ID set exists or not; if the APP ID set does not exist, establishing the APP ID set, and storing an application scene established in the PDU Session determining process and the distributed APP ID in the APP ID set in a corresponding form; and if the APP ID set exists, storing the application scene established in the PDU Session determining process and the allocated APPID in the APP ID set in a corresponding form.

The implementation manner of determining, by the terminal, the URSP selection set according to the APP ID allocated in the PDU Session determining process and the matched URSP may be: the terminal judges whether the URSP selection set exists or not; if the URSP selection set does not exist, establishing the URSP selection set, and storing the APP ID distributed in the PDU Session determining process and the matched URSP in the URSP selection set in a corresponding form; if the URSP selection set exists, determining whether the matching frequency of the APP ID and the URSP is the maximum frequency of all frequencies corresponding to all URSPs matched with the APP ID, if so, updating the URSP corresponding to the APP ID which is the same as the allocated APP ID in the URSP selection set to be the matched URSP, and if not, keeping the existing URSP selection set.

As can be seen, in this example, the terminal may perform URSP matching on multiple APPs installed in the home terminal device, create an application scenario, record APP ID, record URSP, and create a PDU Session for an APP that is successfully subjected to URSP matching, and create an application scenario set, APP ID set, and URSP selection set for all APPs that are successfully subjected to URSP matching, thereby determining a PDU Session for an application program according to the application scenario.

In one possible example, the method further comprises: and when the terminal unloads the target APP, disconnecting the PDU Session currently corresponding to the target APP, and deleting the corresponding relation between the application scene of the target APP and the APPID in the APP ID set and the corresponding relation between the APP ID of the target APP and the URSP in the URSP selection set.

In a specific implementation, the terminal may also reserve, in the APP ID set, a corresponding relationship between the application scene and the APP ID in the APPID set corresponding to the unloaded APP and a corresponding relationship between the APPID and the URSP of the target APP in the URSP selection set for a period of time, such as a day, a week, and the like, and the specific duration may be set by the user, or the terminal may perform intelligent setting based on data used by the user, which is not limited uniquely here.

As can be seen, in this example, for an offloaded APP, a terminal may disconnect a PDU Session of the APP, and update an APP ID set, a URSP selection set, and a possibly existing application scene set synchronously, so as to ensure consistency of information in the APP ID set, the URSP selection set, and the possibly existing application scene set.

In one possible example, the method further comprises: and the terminal routes the data stream of the target application program to the first PDU Session for transmission.

And the terminal routes the data stream of the target application program to the first PDU Session for transmission so as to realize the communication between the terminal and the network equipment.
