Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.
The definitions or explanations of the concepts and terms referred to in this application are as follows.
Application program APPIt refers to various applications installed by the device, such as a video application, a browser application, and the like.
Protocol Data Unit (PDU)And refers to the unit of data passed between peer levels. 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).
PDU Session SessionAnd is a granularity unit of a slice network in the fifth generation 5G mobile communication system.
Network slicingThe method is a networking mode according to needs, and can enable an operator to 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 bearer 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.
User equipment Route option strategy (UE Route Selection Policy, URSP)The 5G core network 5GC is from a Policy Control Function (PCF) to a User equipment (User equipment)ment, UE). The UE uses this policy to determine how to route the data outbound path. The UE may determine, via the URSP rules, whether the detected application may be associated with an already established PDU session, may route to a non-3GPP tunnel outside of the PDU session, or may establish a new PDU session. An important input data in the URSP rule is the parameters in the Traffic Descriptor (TD), which can be carried by the application when initiating the network request. After the operating system acquires the Traffic Descriptor parameter associated with the application program and the UE acquires the URSP rule list from the network, matching a corresponding routing Descriptor RSD according to the rule evaluated by the URSP, and then selecting a data route according to a routing path represented by the RSD parameter.

Currently, in the 3rd Generation Partnership Project (3 GPP) protocol, UE Route Selection Policy (URSP) evaluation requires that a path Descriptor (TD) parameter associated with an application be matched with a Traffic Descriptor parameter in a URSP rule, and then a corresponding routing path is created for the application according to a routing Descriptor (RSD) in the URSP rule that is successfully matched. How to select a routing path for an application is not explicitly agreed at present.
In view of the above problem, an embodiment of the present application provides a routing method for an application program, which is described in detail below with reference to the accompanying drawings.
Referring to fig. 2A, fig. 2A is a schematic flowchart illustrating a routing method for an application according to an embodiment of the present application, where as shown in the figure, the method includes:
step 201, the terminal obtains an identity ID of a first application program APP.
The first APP may be a system application or a third-party application installed in advance in the terminal, such as a video APP, a game APP, a chat APP, and the like, which is not limited herein. The APP ID specifically refers to identification information of the APP, such as the name of the APP.
Step 202, the terminal queries a preset protocol data unit PDU Session set by using the first APP ID as a query identifier, and obtains a first PDU Session of the first application program APP, wherein the PDU Session set comprises a corresponding relation between the ID of the APP and the PDU Session.
The specific representation form of the PDU Session set may be various, and is not limited herein.
For example, the PDU Session set may be a PDU Session configuration file, and the PDU Session n of APP n is represented by the following format:
{APPn，PDU Session n}。
for another example, the PDU Session set may be an IP routing table as shown in table 1, where APP1, 3, 4, and 5 are pre-installed applications, APP1 ID corresponds to PDU Session1, APP3 ID corresponds to PDU Session3, APP4 ID corresponds to first PDU Session4, and APP5 ID corresponds to first PDU Session 5.
TABLE 1 IP ROUTING TABLE
And 203, the terminal routes the data flow of the first APP to the first PDU Session for transmission.
In a specific implementation, the operating system of the terminal may perform steps 201 to 203, and step 203 may assist data processing and transmission through the baseband chip and the radio frequency system.
It can be seen that, in this embodiment, the terminal first acquires a first application APP identity ID, then, with the first APP ID as a query identifier, queries a preset protocol data unit PDU Session set, acquires a first PDU Session of the first application APP, where the PDU Session set includes a correspondence between the ID of the APP and the PDU Session, and finally routes a data stream of the first APP to the first PDU Session for transmission. Through maintaining PDU Session set, the terminal can be according to accurate for APP selection route of APP ID to on all routes the application program IP data package that APP ID corresponds to the PDU Session that corresponds.
In one possible example, the method further comprises: the terminal acquires a plurality of APPs installed at the terminal; the terminal establishes a PDScess for an APP successfully matched with at least one URSP (routing policy and user equipment) in the plurality of APPs, wherein the successful URSP matching means that the TD parameter of a path descriptor of the URSP corresponding to the APP only comprises the ID of the APP, and the routing description RSD of the URSP indicates that PDU Session needs to be established; and the terminal creates the PDU Session set according to the PDU Session of the APP successfully matched with the terminal.
The plurality of APPs may be all APPs installed in the home device scanned by the terminal.
As can be seen, in this example, the terminal may perform URSP matching on multiple APPs installed in the home terminal device, create a PDU Session for the APP successfully matched by the URSP, and create a PDU Session set for all APPs successfully matched by the URSP, thereby implementing the routing path selection for the application program according to the URSP.
In this possible example, the establishing, by the terminal, a PDU Session for an APP in which a routing policy URSP of at least one of the plurality of APPs is successfully matched includes:
the terminal executes the following steps aiming at each APP in the plurality of APPs to obtain the PDUSES of at least one APP;
the terminal queries a URSP set of a user equipment routing strategy by taking the currently processed APP ID as a query identifier;
if the TD parameter only comprises the URSP of the APP ID currently processed, judging whether the RSD in the inquired URSP indicates that PDU Session needs to be established or not, wherein the URSP set comprises a plurality of URSPs, and each URSP comprises a corresponding relation between the TD parameter and a routing descriptor RSD;
if yes, establishing PDU Session for the APP currently processed according to the RSD inquired in the URSP,
if not, determining that the currently processed APP is the APP with failed matching;
if the URSP with the TD parameter only including the currently processed APP ID is not inquired, determining that the currently processed APP is the APP with failed matching.
Wherein the TD parameter of each URSP comprises at least one of the following: the application program comprises an identity identification APP ID, an operating system identity identification OS ID, a data network name DNN, an internet protocol IP triple, a domain Descriptor DomainDescriptor, a non-internet protocol Descriptor non-IP Descriptor and connection capabilities ConnectionCapabilities.
The TD parameter obtaining mode comprises any one of the following modes:
transmitting the application program of the terminal to an operating system through an interface;
presetting by an operating system of the terminal;
storing the data in a Subscriber Identity Module (SIM) card; and the number of the first and second groups,
and receiving the TD parameters sent by the network equipment.
In specific implementation, after determining that the currently processed APP is the APP with the matching failure, the terminal obtains the next unprocessed APP and repeatedly executes the step until the last APP in the multiple APPs is processed.
In this possible example, the terminal obtains multiple APPs installed at the home terminal, including: the terminal obtains a plurality of APPs installed at the terminal when the terminal is started.
In this possible example, the method further comprises: the terminal receives the set of URSPs from a network device. The terminal may specifically receive the URSP set from the network device when the terminal is powered on. The terminal can update the original URSP set stored locally according to the URSP set to obtain an updated URSP set.
In this possible example, the method further comprises: and the terminal acquires the locally stored URSP set. The terminal may obtain the locally stored set of URSPs at power-on.
In addition, the terminal will not create a PDU Session for the APP with failed matching, and when these APPs subsequently request data transmission, the terminal will configure the PDU Session for them in real time (new or binding existing or using non-3GPP path).
As can be seen, in this example, the terminal can create PDU sessions for APPs successfully matched with the URSP without omission by traversing multiple APPs, thereby ensuring service comprehensiveness and accuracy.
In one possible example, the method further comprises: and when the terminal unloads the first application program, disconnecting the first PDU Session and deleting the corresponding relation between the first APP and the first PDUSESS in the PDU Session set.
In a specific implementation, the terminal may also reserve the PDU Session for a period of time, such as one day, one week, etc., without changing the unloaded APP in the PDU Session set, where the specific duration may be set by the user, or the terminal may perform intelligent setting based on the user usage data, where the specific duration is not limited uniquely. For example, the terminal determines that the APP is the APP used by the user at a high frequency according to information such as the application use duration and frequency of the user, predicts that the user will still install the APP back within one week, and may reserve a PDU Session time of the APP for one week.
As can be seen, in this example, for an unloaded APP, the terminal disconnects the PDU Session of the APP, and synchronously updates the PDU Session set, thereby ensuring the consistency of PDU Session information in the PDU Session set.
In one possible example, the method further comprises: when a second APP is installed on the terminal, acquiring the ID of the second APP; the terminal queries a URSP set by taking the second APP ID as a query identifier, and queries a second URSP of which the TD parameters only comprise the second APP ID; the terminal judges that a second RSD indication in the second URSP needs to establish the PDUSESS; the terminal establishes a second PDU Session for the second APP according to a second RSD in the second URSP; and the terminal adds the corresponding relation between the second APP and the second PDU Session to the PDU Session set.
The URSP set may be a set of URSPs pre-stored in the home terminal, or a set of URSPs requested from the network device in real time, which is not limited herein.
In addition, the terminal may also first determine whether the second APP is an APP that was unloaded in a short time period, and if so, may directly query the PDU Session set, determine that the PDU Session of the second APP has not been deleted, and notify the system to update the PDU Session of the second APP so as not to delete any more, and continue to retain.
As can be seen, in this example, when a new APP is installed, the terminal may query the adapted URSP in real time, create a PDU Session for the terminal if matching is successful, and synchronously update a PDU Session set.
In one possible example, the method further comprises: the terminal receives a URSP updating instruction from the network equipment; the terminal updates the URSP set of the local terminal according to the URSP updating instruction; and the terminal updates the PDU Session set according to the updated URSP set.
The URSP update instruction may be issued by a network device triggered by an operator or an APP provider, or the terminal may request update periodically or request update as needed.
In a specific implementation, the terminal updates the PDU Session set according to the updated URSP set, specifically including switching, deleting, adding, etc. of the PDU Session of the existing APP at the local terminal,
if the RSD of the URSP of the first APP is updated to indicate that a non-3GPP access except the PDU Session needs to be used, the terminal deletes the corresponding relation between the first APP in the PDU Session set and the first PDU Session.
If the updated RSD of the URSP of the first APP indicates that the first APP can be associated with the established PDU Session, the terminal switches the first PDU Session to an existing other PDU Session, and updates the corresponding relationship between the first APP and the first PDU Session in the PDU Session set.
Therefore, in this example, the terminal can update the URSP set of the local terminal based on the URSP update instruction, update the PDU Session of the existing APP synchronously, and update the corresponding relationship between the APP and the PDU Session in the PDU Session set, thereby ensuring information consistency and system stability.
The routing method of the application program of the present application is further described below with reference to specific examples.
As shown in fig. 2B, the routing method for an application provided in the embodiment of the present application includes the following steps:
step 21, the terminal is powered on and sends a preset message (for example, a cell registration request, etc.) to the network device.
And step 22, the network equipment receives the preset message and issues a URSP rule table to the terminal.
And step 23, the terminal receives the URSP rule table and updates the URSP rule table of the terminal to obtain an updated rule table.
Step 24, the terminal inquires all the APPs and APP IDs installed at the terminal; establishing a corresponding PDU Session for the APP successfully matched with the URSP by inquiring the URSP rule in the URSP rule table; and establishing a corresponding relation between the application program APP and the PDU Session:
and 25, the terminal establishes an operating system IP routing table through the APPID and the operating system process ID, and binds the APPID to the PUD Session.
In this example, the terminal completes traversal detection of pdusesion creation conditions of all APPs of the terminal through the URSP rule table at the startup stage, and does not create IP routing tables for all APPs meeting the conditions, thereby improving the use convenience and system efficiency of the applications.
