Fig. 3 is a flowchart illustrating a method for processing a network slice according to an exemplary embodiment of the present application. In the embodiment of the present application, when the usage state of the target service is being used, the network service is provided for the target service by using the first network slice before updating as an example. The method comprises the following steps:
step 301: the network equipment sends URSP to the terminal, the URSP comprises a plurality of pieces of routing information, and each piece of routing information corresponds to one service.
When the terminal accesses the network equipment, the terminal sends an access request to the network equipment, and the access request carries the terminal identifier of the terminal. The network equipment receives the access request, acquires the URSP of the terminal based on the terminal identification, and sends the URSP to the terminal, wherein the URSP comprises a plurality of pieces of routing information, and each piece of routing information corresponds to one service. The service is an APP or some function in an APP.
In a possible implementation manner, as long as the terminal accesses the network device, the network device sends the URSP to the terminal, that is, the network device sends the URSP to the terminal each time the terminal accesses the network device, so that the operation is simple, the process of judging whether the URSP needs to be sent historically is saved, and the efficiency is improved. In another possible implementation manner, the network device sends the URSP to the terminal only when the terminal accesses the network device for the first time, so that transmission resources are saved.
Step 302: the terminal receives the URSP of the network equipment and stores the URSP.
After the terminal stores the URSP, when a certain service is subsequently operated, a network slice is established based on the routing information corresponding to the service in the URSP, that is, step 303 is executed.
The URSP comprises a plurality of pieces of routing information; in a possible implementation manner, the terminal stores the URSP, that is, stores a plurality of pieces of routing information, so that the terminal can subsequently use services corresponding to the plurality of pieces of routing information, thereby enriching the use scenario.
In another possible implementation manner, each piece of routing information corresponds to one service, and the terminal only stores the routing information corresponding to the service that the terminal has; correspondingly, the step of the terminal storing the URSP comprises the following steps: the terminal selects at least one piece of target routing information from the URSP, the target routing information is routing information corresponding to the service which the terminal has, and the at least one piece of target routing information is stored. In the embodiment of the application, the terminal only stores the routing information corresponding to the service which the terminal has, but not stores the routing information corresponding to the service which the terminal does not have, so that the requirement of the terminal can be met, and the storage space can be saved.
Step 303: when the target service is operated, the terminal determines first routing information corresponding to the target service from the URSP, establishes a first network slice with the network equipment based on the first routing information, and provides the network service for the target application through the first network slice.
And when the terminal starts the target service, determining that the terminal runs the target service. The step that the terminal establishes the first network slice with the network equipment based on the first routing information comprises the following steps: the terminal establishes a Packet Data Unit Session (PDU Session) with the network device based on the first routing information, and obtains a first network slice by configuring some parameters in the PDU Session. The first network slice can provide customized network services for the target service, and the network services can be service contents such as ultra-high speed or ultra-low time delay.
It should be noted that, the URSP may or may not have first routing information corresponding to the target service; under the condition that first routing information corresponding to the target service does not exist in the URSP, the terminal sends a first acquisition request to the network equipment based on the target service, wherein the first acquisition request carries a service identifier of the target service; the network equipment receives the first acquisition request, acquires first routing information based on the service identifier of the target service, and sends the first routing information to the terminal.
In the embodiment of the application, when the first routing information does not exist in the URSP, the first routing information may be acquired from the network device through the first acquisition request, so that the first routing information may be acquired in time when the first routing information does not exist in the URSP, and further subsequent operations may be performed.
Step 304: and under the condition that the routing information corresponding to the target service is changed from the first routing information to the second routing information, the terminal determines the use state of the target service.
The usage status includes being used or not used; being used means that the target service is running in the foreground; being used means that the target service is running in the foreground, and not being used means that the target service exits the foreground or the target service is turned off.
The routing information corresponding to the target service may be changed due to a network package change of the terminal, an expiration of the network package, a network subscription signed by the terminal, or a change of an accessed cell. In a possible implementation manner, when the routing information corresponding to the target service changes, the network device sends an update request to the terminal, where the update request carries at least the service identifier of the target service and the second routing information, and the update request may also carry the first routing information. And the terminal receives the updating request, and determines that the routing information corresponding to the target service is changed from the first routing information into the second routing information based on the updating request. In the embodiment of the application, the network equipment informs the terminal that the routing information corresponding to the target service is changed based on the updating request, so that the terminal does not need to perform independent judgment, and the resources of the terminal are saved.
In another possible implementation manner, the terminal itself senses whether the routing information corresponding to the target service changes. For example, when a cell accessed by a terminal changes, routing information corresponding to a target service changes correspondingly; the terminal determines that the routing information corresponding to the target service changes when the cell accessed by the terminal is changed from the first cell to the second cell. In this implementation, the terminal stores the first routing information before the change and the second routing information after the change in advance. The changed second routing information is routing information corresponding to a target service of the terminal in the second cell. When the terminal accesses the second cell in history, the network device sends the second routing information to the terminal, and the terminal stores the second routing information. In the embodiment of the application, the terminal determines whether the routing information corresponding to the target service changes or not based on the accessed cell, so that the condition of time delay in judgment caused by network problems is avoided, and the judgment efficiency is improved.
Step 305: and under the condition that the use state is in use, the terminal determines that the target network slice is the first network slice and continues to provide the network service for the target service through the first network slice.
When the usage state is in use, the terminal suspends releasing the first network slice and suspends updating the network slice.
Step 306: in the case where the usage state is changed from being used to not being used or the usage state is not used, the terminal releases the first network slice.
In the case that the usage status is changed from being used to unused or the usage status is unused, the terminal releases the first network slice at this time does not affect the usage of the target service.
Step 307: and the terminal establishes a second network slice with the network equipment based on the second routing information, and provides the network service for the target service through the second network slice under the condition that the use state is changed from unused to used.
In the embodiment of the application, after the terminal releases the first network slice, the second network slice is directly established, so that when the target service is on line again, the second network slice can be directly used, the efficiency of subsequently using the second network slice is improved, and the smoothness of the target service is further improved.
In the embodiment of the application, when the routing information corresponding to the target service changes, the terminal monitors whether the target service is being used, and under the condition that the target service is being used, the updating operation of the network slice is delayed, so that the phenomenon of blockage caused by network disconnection due to the updating operation of the network slice is avoided, and the smoothness of the target service is improved.
Fig. 4 is a flowchart illustrating a method for processing a network slice according to an exemplary embodiment of the present application. In the embodiment of the present application, when the usage state of the target service is used, the network service is provided for the target service by using the first network slice before updating as an example. The method comprises the following steps:
step 401: the network equipment sends URSP to the terminal, the URSP comprises a plurality of pieces of routing information, and each piece of routing information corresponds to one service.
Step 402: the terminal receives the URSP of the network equipment and stores the URSP.
Step 403: when the target service is operated, the terminal determines first routing information corresponding to the target service from the URSP, establishes a first network slice with the network equipment based on the first routing information, and provides the network service for the target application through the first network slice.
Step 404: and under the condition that the routing information corresponding to the target service is changed from the first routing information to the second routing information, the terminal determines the use state of the target service.
Step 405: and under the condition that the use state is in use, the terminal determines that the target network slice is the first network slice and continues to provide the network service for the target service through the first network slice.
Step 406: in the case where the usage state is changed from being used to not being used or the usage state is not used, the terminal releases the first network slice.
It should be noted that steps 401-406 are the same as steps 301-306, and are not described herein again.
Step 407: and in the case that the use state is changed from unused to being used, establishing a second network slice with the network equipment based on the second routing information, and providing the network service for the target service through the second network slice.
In the embodiment of the application, after the terminal releases the first network slice, the second network slice is not established temporarily, and when the target service is online again, that is, when the second network slice needs to be used, the second network slice is established, so that the waste of resources is avoided.
Fig. 5 is a flowchart illustrating a method for processing a network slice according to an exemplary embodiment of the present application. In this embodiment, a case where the updated second network slice is established in advance by the terminal is described as an example where the second network slice provides the network service for the target service. The method comprises the following steps:
step 501: the network equipment sends URSP to the terminal, the URSP comprises a plurality of pieces of routing information, and each piece of routing information corresponds to one service.
Step 502: the terminal receives the URSP of the network equipment and stores the URSP.
Step 503: when the target service is operated, the terminal determines first routing information corresponding to the target service from the URSP, establishes a first network slice with the network equipment based on the first routing information, and provides the network service for the target application through the first network slice.
Step 504: and under the condition that the routing information corresponding to the target service is changed from the first routing information to the second routing information, the terminal determines whether to establish a second network slice.
The second network slice is established with the network device based on the second routing information; where a second network slice has been established at the terminal, step 505 is performed. In a possible implementation, the terminal releases the first network slice and establishes a second network slice with the network device based on the second routing information, when the terminal does not establish the second network slice; in another possible implementation manner, in the case that the terminal does not establish the second network slice, the terminal provides the network service for the target service according to the method of steps 304-307 or steps 404-407.
Step 505: and under the condition that the terminal establishes the second network slice, determining the target network slice as the second network slice, and providing the network service for the target service through the second network slice.
Under the condition that the terminal establishes the second network slice, the terminal does not need to repeatedly establish the second network slice, so that the terminal provides network service for the target service through the second network slice, the network service provided by the second network slice can be timely obtained, and the service quality is improved.
The terminal directly releases the first network slice under the condition that the terminal establishes the second network slice; or, the terminal releases the first network slice after the terminal provides the network service for the target service through the second network slice.
Fig. 6 is a flowchart illustrating a method for processing a network slice according to an exemplary embodiment of the present application. In the embodiment of the present application, a process in which the terminal establishes the updated second network slice in advance is taken as an example for description. The method comprises the following steps:
step 601: and under the condition that the historical routing information corresponding to the target service is the second routing information, the terminal establishes a second network slice with the network equipment based on the second routing information, and provides the network service for the target service through the second network slice.
When the terminal accesses the cell corresponding to the second routing information in history, the network device sends the second routing information to the terminal.
Step 602: and under the condition that the routing information corresponding to the target service is changed from the second routing information into other routing information, the terminal continuously reserves the second network slice.
In a possible implementation manner, the terminal keeps all the network slices established in history, that is, the terminal directly keeps the second network slice, thereby facilitating subsequent use. In another possible implementation, the terminal first determines whether the second network slice has a reserved value, that is, whether the second network slice is likely to be used later, and then reserves the second network slice only when determining that the second network slice is likely to be used later, and then does not reserve the second network slice, that is, releases the second network slice when determining that the second network slice is unlikely to be used later, so that the second network slice is utilized most likely. Correspondingly, the step of the terminal continuing to reserve the second network slice comprises the following steps: the terminal determines a use parameter of the second network slice, wherein the use parameter is used for representing the probability size of the second network slice to be used subsequently; in the event that the usage parameter exceeds a preset threshold, the second network slice continues to be retained.
In one possible implementation, different routing information for the same target service corresponds to different cells; correspondingly, the step of the terminal determining the usage parameter of the second network slice includes: and the terminal determines a cell corresponding to the second routing information, determines the probability of accessing the cell by the terminal, and determines the probability as the use parameter.
In another possible implementation, the more times the history of the network slice is used, the greater the probability of subsequent use; correspondingly, the step that the terminal determines the use parameter of the second network slice comprises the following steps: the terminal determines the number of times the history of the second network slice is used, and determines a use parameter matching the number of times.
Wherein the terminal stores a usage record of the network slice historically established, and determines the number of times the history of the second network slice is used based on the usage record.
It should be noted that, in the case that the usage parameter does not exceed the preset threshold, the terminal does not reserve the second network slice, that is, the terminal releases the second network slice. The preset threshold may be set and changed as needed, and in the embodiment of the present application, the preset threshold is not specifically limited.
In the embodiment of the application, when the routing information corresponding to the target service is changed from the second routing information to other routing information, the terminal continues to keep the second network slice so as to be convenient for the subsequent use of the second network slice, so that the situation that the target service is disconnected due to reestablishment of the network slice is avoided, the phenomenon that the target service is blocked is reduced, and the fluency of the target service is improved.
Fig. 7 is a flowchart illustrating a method for processing a network slice according to an exemplary embodiment of the present application. In the embodiment of the present application, a process of establishing an updated second network slice in advance at a terminal is taken as an example for description. The method comprises the following steps:
step 701: and the terminal sends a second acquisition request to the network equipment, wherein the second acquisition request is used for acquiring at least one piece of routing information corresponding to the target service.
The second obtaining request carries a service identifier of the target service, so that the network equipment can obtain the corresponding at least one piece of routing information conveniently, and therefore at least one network slice is established at one time based on the at least one piece of routing information, and the network slice is used later.
It should be noted that, when the terminal accesses the network device, the terminal sends a second acquisition request to the network device; or, the terminal sends the second acquisition request to the network device when the terminal is idle, and in this embodiment of the application, the timing at which the terminal sends the second acquisition request to the network device is not specifically limited.
Step 702: and the network equipment receives the second acquisition request and acquires at least one piece of routing information corresponding to the target service.
The network device stores routing information corresponding to different cells corresponding to the same service, that is, stores a corresponding relationship between a service identifier and the routing information; correspondingly, the network device obtains at least one piece of routing information corresponding to the target service from the corresponding relation between the service identifier and the routing information based on the service identifier of the target service.
In a possible implementation manner, after the network device obtains the at least one piece of routing information, step 703 may be directly performed; in another possible implementation manner, after obtaining the at least one piece of routing information, the network device screens the at least one piece of routing information to screen out routing information that the terminal may access the cell, and then performs step 703.
Step 703: the network equipment sends at least one piece of routing information corresponding to the target service to the terminal.
In step 702, the network device filters out the routing information that the terminal may access the cell, and in this step, the network device sends the filtered routing information to the terminal.
Step 704: the terminal receives the at least one routing information, and establishes at least one network slice with the network device based on the at least one routing information, the at least one network slice including a second network slice.
In the embodiment of the application, the terminal acquires at least one piece of routing information at one time through the second acquisition request, establishes at least one network slice, and then subsequently uses the network slice, so that the situation of network breaking of the target service caused by reestablishment of the network slice is avoided, the phenomenon of blocking of the target service is reduced, and the fluency of the target service is improved.
Fig. 8 is a flowchart illustrating a method for processing a network slice according to an exemplary embodiment of the present application. In the embodiment of the present application, an example of selecting a target network slice from a first network slice and a second network slice is described. The method comprises the following steps:
step 801: the network equipment sends URSP to the terminal, the URSP comprises a plurality of pieces of routing information, and each piece of routing information corresponds to one service.
Step 802: the terminal receives the URSP of the network equipment and stores the URSP.
Step 803: when the target service is operated, the terminal determines first routing information corresponding to the target service from the URSP, establishes a first network slice with the network equipment based on the first routing information, and provides the network service for the target application through the first network slice.
It should be noted that steps 801-.
Step 804: and under the condition that the routing information corresponding to the target service is changed from the first routing information to the second routing information, the terminal acquires slice configuration information of the target service, wherein the slice configuration information is used for representing priority level information of the first network slice and the second network slice.
In one possible implementation, the slice configuration information is configured for the target service in advance by the terminal; for example, the slice configuration information is used to indicate that the priority level of a first network slice is higher than the priority level of a second network slice; or the slice configuration information is used to indicate that the priority level of the second network slice is higher than the priority level of the first network slice.
The terminal configures slice configuration information of a target network slice based on the service quality of the first network slice and the service quality of the second network slice. For example, if the service quality of the first network slice is higher than that of the second network slice, the slice configuration information is used to indicate that the priority level of the first network slice is higher than that of the second network slice; as another example, if the service quality of the first network slice is lower than that of the second network slice, the slice configuration information is used to indicate that the priority level of the second network slice is higher than that of the first network slice.
In the embodiment of the application, the terminal configures the slice configuration information of the target service in advance, so that the slice configuration information configured in advance directly carries out subsequent processing, the operation is simple, and the efficiency is high.
In another possible implementation manner, the slice configuration information is updated in real time by the terminal based on the use state of the target service; for example, if the usage status of the target service is being used, the slice configuration information is used to indicate that the priority level of the first network slice is higher than that of the second network slice; when the usage status of the target service is unused, the slice configuration information is used to indicate that the priority level of the second network slice is higher than that of the first network slice.
In the embodiment of the application, the slice configuration information is updated in real time by the terminal based on the use state of the target service, that is, when the use state of the target service is in use, the priority level of the first network slice is higher than that of the second network slice, so that it can be ensured that the target service is not switched when being used, and the first network slice is continuously used to provide the network service for the target service, thereby avoiding the occurrence of network outage caused by switching the network slices, and further improving the fluency.
Step 805: the terminal determines a target network slice with the highest priority level from the first network slice and the second network slice based on the slice configuration information.
For example, if the priority level of the first network slice is higher than that of the second network slice, the terminal determines that the target network slice is the first network slice; if the priority level of the second network slice is higher than that of the first network slice, the terminal determines that the target network slice is the second network slice.
Step 806: and the terminal provides network service for the target service through the target network slice.
For example, if the target network slice is a first network slice, the terminal continues to provide network services for the target service through the first network slice; if the target network slice is the second network slice, the terminal switches the first network slice to the second network slice.
In the embodiment of the application, under the condition that the first network slice and the second network slice coexist, the terminal selects the target network slice from the two network slices based on the priority level information of the two network slices, so that the network slice with the high priority level is ensured to provide network service for the target service, and the service quality is improved.
