It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

For example, at least one of a, b, and c may represent: a, b, c, a and b, a and c, b and c or a and b and c, wherein a, b and c can be single or multiple.
In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
For ease of understanding, a description will first be made of the current 5G network deployment slice scenario.
According to the current 5G network deployment, common co-frequency cells can support the same type of network slice service, and inter-frequency cells support another type of network slice service. While one frequency point cannot necessarily satisfy all slicing service types, a network must deploy two or more frequency points to satisfy actual needs of different services, a 5G base station in an area where a current user is located supports two or more frequency points, such as frequency point 1(NR-Arfcn 1), frequency point 2(NR-Arfcn2), frequency point 3(NR-Arfcn 3).., each frequency point supports different types of slicing services, such as a slicing identifier (S-NSSAI-1) corresponding to NR-Arfcn 1 supporting application 1(APP1), NR-Arfcn2 supporting S-NSSAI-2(APP2), NR-Arfcn 3 supporting S-NSSAI-3(APP3), and the like. At present, a terminal can simultaneously support PDU session establishment of 8 slices (8 application services), but because the terminal cannot know the slice service types supported by a certain frequency point, the terminal can randomly register on a certain frequency point when starting up and registering, and the terminal can only register on one frequency point at the same time. When the frequency point registered by the terminal does not support the application slicing service to be started by the user, the user cannot enjoy the slicing service when using the application service, and the following explains that the user uses the slicing service in a specific scene.
In scenario one: a terminal (UE1) held by a user is powered on and randomly registered on a frequency point 1 (assumed to be NR-Arfcn 1), the frequency point 1(NR-Arfcn 1) can only support the slice service of APP1, the frequency point 2 (assumed to be NR-Arfcn2) supports the slice service of APP2, and if the user wants to use the slice service of APP2, since the frequency point registered by the UE1 is NR-Arfcn 1 and the NR-Arfcn 1 cannot support the slice service of APP2, the UE1 cannot enjoy the slice service of APP 2.
In scenario two: when the APP1 service and the APP2 service are concurrent, a terminal (UE2) held by a user expects that the slice service priority of the APP2 is higher than that of the APP1, and preferentially ensures that the APP2 always shares the slice service, while the APP1 needs the support of NR-Arfcn 1, the APP2 needs the support of NR-Arfcn2, and the UE2 is powered on and registered on the NR-Arfcn 1, so that the UE2 cannot always share the slice service of the APP 2.
For the scenes such as the scenes, according to the current communication protocol, a user has no way to actively switch by setting a mobile phone or passively switch to a frequency point correspondingly supported by a slicing service to be enjoyed by informing a network, so that the requirement of the user cannot be met, and the user experience is greatly reduced.
In order to solve the above problem, embodiments of the present invention provide a frequency point switching method, an electronic device, and a storage medium, which satisfy different user differentiation requirements, and can ensure that a terminal is registered on a frequency point supporting a slicing service that a user prefers to apply, thereby greatly improving user experience.
Fig. 1 shows a flowchart of a frequency point switching method according to an embodiment of the present invention, where the method is applied to a terminal. As shown in fig. 1, the method may include the steps of:
s110, receiving application priority information of a user, wherein the application priority information comprises at least one application and application priority.
Illustratively, the user sets application priority information at the terminal, and the application priority information includes applications and application priorities. The terminal receives application priority information set by a user, and the received application priority information comprises at least one application and the priority of the application. The content included in the application priority information can be seen in table 1 below.
TABLE 1
| Application identification | Priority level |
| APP1 | 1 |
| APP2 | 2 |
| APP3 | 3 |
It should be understood that the user can add applications and set the priorities of the applications at the terminal, edit the priorities of the applications that have been added, and delete the priorities of the applications that no longer need to be set. In the embodiment of the invention, the human-computer interaction interface provided by the terminal is simple in operation interface, the user interface is added with the application priority adding interface, the user can add, delete and edit one application, and each application is added with one priority, so that a common user can operate more intuitively and easily, and the user experience is improved.
And S120, acquiring a slice identifier corresponding to the application, and determining the priority of the slice identifier according to the priority of the application.
Illustratively, after receiving application priority information set by a user, a terminal acquires a slice identifier corresponding to each application in the application priority information, where each application has a corresponding slice identifier, and thus, the priority of each slice identifier can be further determined according to the priority of each application, so that the priority of the slice identifier is encapsulated into slice priority information in subsequent steps and sent to a base station.
It is understood that, in the embodiment of the present invention, the priorities of the applications, the slice identifiers, and the priorities of the slice identifiers are in a one-to-one correspondence relationship, and the priorities of the applications and the slices in which the mapping relationship exists are equal.
In the embodiment of the present invention, the Slice identifier may be Single Network Slice Selection auxiliary Information (S-NSSAI), and identify a Network Slice that correspondingly provides a Slice service for each application through the S-NSSAI. The application and slice identification corresponding to each priority can be seen in table 2 below.
TABLE 2
S130, sending slice priority information to the base station, where the slice priority information includes a slice identifier and a priority of the slice identifier.
Illustratively, the terminal sends slice priority information to the base station through an air interface instruction, where the slice priority information at least includes a slice identifier and a priority of the slice identifier, for example: { (S-NSSAI-1, priority 1); (S-NSSAI-2, priority 2); (S-NSSAI-3, priority 3) }. The priority of each slice determined according to the application priority information set by the user can be acquired through the slice priority information. It can be understood that the slice priority information may further include a terminal identifier and an application identifier corresponding to each slice priority, for example: { UE1, (APP1, S-NSSAI-1, priority 1); (APP2, S-NSSAI-2, priority 2); (APP3, S-NSSAI-3, priority 3) }. The embodiment of the invention does not limit the specific form of the slice priority information.
And S140, receiving a target frequency point switching instruction sent by the base station according to the slice priority information.
Illustratively, when a terminal sends slice priority information to a base station, a target frequency point switching instruction sent by the base station according to the slice priority information is received, the base station can determine a target frequency point which the terminal currently needs to switch according to the slice priority information sent by the terminal and sends the target frequency point switching instruction to the terminal, and the terminal receives the target frequency point switching instruction to trigger a frequency point switching process.
And S150, switching from the currently resident source frequency point to the target frequency point according to the target frequency point switching instruction.
Illustratively, the terminal sends the slice priority information to the base station and receives a corresponding target frequency point instruction from the base station, where the target frequency point instruction indicates that the terminal switches to a frequency point corresponding to the slice service of the first priority, and the terminal executes a process of switching terminal frequency points according to the target frequency point instruction and switches from a currently residing source frequency point to a target frequency point, where the target frequency point supports the slice service of the application of the first priority.
Specifically, after the terminal is started, the terminal normally accesses the flow according to a communication protocol, randomly selects a frequency point (namely a source frequency point) meeting a residence condition, completes 5G initial startup registration, a user terminal (UE) stores URSP (UE routing policy) issued by a network locally, and realizes transmission service of service data by PDU connection service, wherein the PDU connection service is service for exchanging PDU data packets between the UE and a data network DN, and the PDU connection service is realized by initiating establishment of a PDU session through the UE or an application server AF. A PDU session refers to a process of communication between a UE and a DN, and after the PDU session is established, a data transmission channel between the UE and the DN is established, so that a service data transmission service can be implemented. When the terminal receives a target frequency point switching instruction from the base station, the terminal is switched to the target frequency point according to the target frequency point switching instruction, and the corresponding application slicing service can be enjoyed on the target frequency point.
Optionally, before sending the slice priority information to the base station, as shown in fig. 2, the method may further include the following steps:
s210, acquiring a state flag of each application, wherein the state flag is used for indicating the running state of the application, and the running state of the application comprises a starting state or a stopping state.
Illustratively, the terminal receives application priority information set by a user, stores the application priority information, and further determines an operating state of each application, where the operating state includes a start state or a stop state, the start state may be when the user starts the application for the first time or wakes up the application to enter a use state, and the stop state may be an application state in which the user actively closes the application or does not use the application for a long time.
Illustratively, in the terminal running process, the application with the priority added by the user in step S110 is monitored, the information about whether the application is started is stored, and whether the application is started is determined.
In a specific implementation process, after determining the running state of each application in the application priority information, a state flag of each application is set according to the running state of each application, and the state flag is used for indicating the running state of the application. And identifying the application in the starting state by acquiring the state mark of each application.
Illustratively, after receiving application priority information set by a user, storing the priority information of each application, and setting a state flag of each application according to an operation state of each application, wherein the state flag is used for indicating the operation state of the application, and the operation state is a start state or a stop state, and storing information on whether the application is started or not. As an example, the priority and the application, slice identifier, and application status flag corresponding to the priority can be seen from table 3 below.
TABLE 3
| Priority level | Application identification | Section mark | Application status flag |
| 1 | APP1 | S-NSSAI-1 | Start |
| 2 | APP2 | S-NSSAI-2 | Stop |
| 3 | APP3 | S-NSSAI-3 | Start |
S220, encapsulating the slice identifier and the priority of the slice identifier corresponding to the application in the starting state into the slice priority information.
And encapsulating the slice identifier corresponding to the application in the starting state indicated by the state flag and the priority of the slice identifier into slice priority information, wherein if the user does not use the service of the application, namely the running state of the application is not in the starting state, the priority of the application does not need to be considered, and the function of frequency point switching is not needed.
And in the running process of the terminal, acquiring a state mark of each application, monitoring whether the application added with the priority is started or not through the state mark, and when the starting information of the application is updated or the application priority information set by a user is updated, sending the priority information corresponding to all the started applications to the base station.
When it is monitored that an application is switched from a starting state to a stopping state, which indicates that the application stops running, slice priority information needs to be sent to the base station again, information corresponding to the application in the stopping state is eliminated, and slice priority information is updated, so that a slice service provided by a terminal to a user is more accurate. For example, according to the application status flag shown in table 3, the following information is encapsulated into the slice priority information transmitted to the base station: { UE1, (APP1, S-NSSAI-1, priority 1); (APP3, S-NSSAI-3, priority 3) }.
Optionally, as shown in fig. 3, after sending the slice priority information to the base station, before receiving a target frequency point switching instruction sent by the base station according to the slice priority information, the method may further include the following steps:
and S310, receiving a target frequency point signal measurement request sent by the base station.
Illustratively, a terminal sends slice priority information to a base station, the slice priority information includes a slice identifier and a priority of the slice identifier, and after the base station determines that a frequency point currently residing in the terminal does not support a slice service corresponding to a first priority according to the slice priority information sent by the terminal, a target frequency point supporting the slice service corresponding to the first priority needs to be searched, and then a target frequency point switching instruction is sent to the terminal. Before sending a target frequency point switching instruction to a terminal, a base station needs to acquire the signal quality of a target frequency point so as to determine whether the target frequency point meets a switching condition according to the signal quality. Therefore, before sending the target frequency point switching instruction to the terminal, the base station sends a target frequency point signal measurement request to the terminal. After receiving a target frequency point signal measurement request sent by a base station, a terminal measures signals of a target frequency point and sends a measurement result to the base station, so that the base station judges whether the frequency point switching condition is met or not according to the measurement result.
And S320, measuring the signal intensity of the target frequency point according to the target frequency point signal measurement request to obtain a target frequency point signal intensity indicated value.
Illustratively, the terminal measures the signal strength of the target frequency point according to a target frequency point signal measurement request from the base station to obtain a target frequency point signal indicated value, where the target frequency point signal indicated value is used to indicate the signal quality of the target frequency point.
And S330, the indicated value of the signal intensity of the target frequency point is returned to the base station.
Illustratively, the terminal measures the signal intensity of a target frequency point, and after obtaining a target frequency point signal intensity indicated value, feeds the target frequency point signal intensity indicated value back to the base station, and when the base station determines that the target frequency point signal intensity indicated value meets an intensity threshold, the terminal receives a target frequency point switching instruction from the base station and switches to the target frequency point.
According to the scheme of the embodiment of the invention, the terminal receives application priority information set by a user, acquires the slice identifier corresponding to the application, determines the priority of the slice identifier corresponding to the application according to the application priority, then sends the slice priority information to the base station, and receives a target frequency point switching instruction sent by the base station according to the slice priority information, so that the terminal is adaptively switched to a frequency point capable of supporting the slice service of the application with the highest priority, the personalized requirements of the user are met, and the user experience is greatly improved.
It should be noted that fig. 1 above describes the present invention from the terminal side, and the following describes the present invention from the base station side with reference to fig. 4, and the terminal side and the base station side correspond to each other.
Fig. 4 shows a flowchart of a frequency point switching method according to an embodiment of the present invention, where the method is applied to a base station. As shown in fig. 4, the method may include the steps of:
s410, receiving slice priority information sent by a terminal, wherein the slice priority information comprises a slice identifier and the priority of the slice identifier.
Illustratively, the base station receives slice priority information from the terminal, where the slice priority information includes a slice identifier and a priority of the slice identifier, and may feed back a reception instruction to the terminal, where the reception instruction indicates that a slice priority message sent by the terminal has been received. The base station may store the received slice priority information locally.
And S420, determining a target slice identifier corresponding to the first priority according to the slice identifier and the priority of the slice identifier.
Illustratively, the base station stores the priority application message of each user terminal (UE) locally, and establishes the correspondence between the priorities of the UE, the application, the slice identifier and the slice identifier. And determining a target slice identifier corresponding to the highest priority (namely, the first priority) set by the user according to the slice identifier and the priority of the slice identifier.
In some embodiments, the slice is identified as S-NSSAI, by which a network slice corresponding to a slice service provided for an individual application is identified.
And S430, when the frequency point currently resided in the terminal is determined not to support the slicing service corresponding to the target slicing identifier, determining the target frequency point corresponding to the target slicing identifier.
Illustratively, a target slice identifier corresponding to a first priority set by a user has a corresponding slice service, and when a frequency point currently residing in a terminal does not support the slice service corresponding to the target slice identifier, it is necessary to determine a target frequency point corresponding to the target slice identifier, and send a target frequency point switching instruction to the terminal.
In a specific implementation, NSSAI corresponding to each cell frequency point may be stored locally in the base station. The base station can obtain a first NSSAI corresponding to a frequency point where the terminal resides currently from the locally stored NSSAI; searching a target S-NSSAI in the first NSSAI; when the first NSSAI does not contain the target S-NSSAI, the fact that the frequency point where the terminal currently resides does not support the slicing service corresponding to the target S-NSSAI can be determined.
And when the frequency point where the terminal currently resides is determined not to support the slicing service corresponding to the target S-NSSAI, the base station acquires a second NSSAI corresponding to the frequency point of the adjacent cell, and when the second NSSAI contains the target S-NSSAI, the frequency point corresponding to the second NSSAI containing the target S-NSSAI is determined as the target frequency point.
And S440, sending a target frequency point switching instruction to the terminal so that the terminal is switched to the target frequency point according to the frequency point switching instruction.
Illustratively, the base station judges that the frequency point where the terminal currently resides does not support the slicing service corresponding to the first priority, and sends a target frequency point switching instruction to the terminal, so that the terminal is switched to the target frequency point according to the frequency point switching instruction.
Optionally, in step S440, before sending the target frequency point switching instruction to the terminal, as shown in fig. 5, the method may further include the following steps:
