In the mobile terminal shown in fig. 1, the processor 1001 is configured to execute a network access application program in the memory 1003, and implement the following steps:
acquiring first network slice information and second network slice information, wherein the first network slice information is network slice information supported by terminal equipment, and the second network slice information is network slice information supported by a user identification card in a terminal;
and selecting a corresponding network slice access network according to the first network slice information and the second network slice information.
To better illustrate the examples of the present application, some terms used in the present application are explained in the following table:
referring to fig. 2 and 3, fig. 2 is a schematic view illustrating an operation flow of the network access method of the present application, and fig. 3 is an interaction schematic view of an embodiment of the network access method of the present application; the network access method comprises the following steps:
step S10, acquiring first network slice information and second network slice information, wherein the first network slice information is network slice information supported by terminal equipment, and the second network slice information is network slice information supported by a user identification card in the terminal;
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 network slice can divide a plurality of logic networks with different functions and characteristics on one physical network, and simultaneously supports a plurality of service scenes. Based on the network slicing technology, the utilization rate of network resources can be improved, and the network resources required by different service scenes can be isolated.
The terminal equipment can be configured with a network slice function, different sub-network slices are configured, and the network is accessed through the different sub-network slices, so that access of different scenes and services is realized.
In an embodiment, referring to fig. 4, the process of configuring the network slice information by the terminal device includes:
step S11, responding to the scene information setting operation of the network slice, and acquiring the device type of the terminal device;
step S12, determining the identification information of the network slice according to the device type;
step S13, configuring the identification information for the terminal device, where the identification information identifies a scene identifier of a network slice supported by the terminal device.
The scene information of the network slice corresponds to the type of the device, for example, the time delay requirements are different, the scenes are different, a high time delay scene and a low time delay scene are different, the high time delay scene and the low time delay scene are relative concepts rather than absolute concepts, and the high time delay scene and the low time delay scene can be divided by setting a time delay value. The types of the terminal equipment can be divided into mobile terminal equipment, unmanned equipment, non-mobile equipment and the like, and the network slicing scenes required by different service types are different. For example, the type of the mobile terminal device needs a communication embodied scenario, and a scenario using APP or instant messaging application needs to set corresponding network slice identification information. After the identification information of the network slice needing to be configured is determined, the identification information is configured for the terminal equipment and is configured as the network slice identification information of the scene information supported by the current terminal equipment. Certainly, the network slice information supported by the terminal is not one-time invariant and can change along with different configured identification information, the hardware and the architecture of the terminal equipment support the change, and the network slice access is selected to optimize the network access only by setting the corresponding identification information according to the requirement when the hardware and the architecture of the terminal equipment are external. Different network slices set different identification information for different scene information, and when a network slice is selected, the identification information can be selected according to the service requirements because the different scene information meets the requirements of different service types, and the network slice meeting the requirements is correspondingly selected to complete network access, thereby completing service operation.
Optionally, when the requirements of different terminal devices are different, the configured supported network slices are different, for example, a terminal network slice scene identifier is stored in NV or a partition as an identifier (named UE _ NSSAI), and the scene parameter format is as follows:
UE _ NSSAI, 1 represents eMBB, 2 represents URLLC, and 3 represents MIoT;
1) if the requirement on time delay is not high and no mobility exists, the water and electricity meter equipment stores the value as 1;
2) high throughput, high security devices such as drones, unmanned vehicles, etc. are stored as 2;
3) the person-to-person communication experience of the access equipment is improved, and the equipment such as a mobile phone is stored as 3.
For the subscriber identity module, for example, the network slice scenario identifier supported by the SIM card, for example, the addition of the EF _ NSSAI file identifier of the SIM card to the network switching scenario identifier corresponds to the following steps
1) If the requirement on time delay is not high and no mobility exists, the value of the water and electricity meter equipment is 1;
2) high throughput, high security, e.g., a device value of 2 for unmanned aerial vehicles, unmanned automobiles, etc.;
3) the person-to-person communication experience of the access equipment is improved, and the equipment value of a mobile phone and the like is 3.
The set marks 1, 2 and 3 are supported network slice information, and the marks 1, 2 and 3 of the terminal equipment are first network slice information; the SIM card is the second network slice information of the subscriber identity card. And after the operation of network access is triggered, acquiring first network slice information and second network slice information supported by the terminal according to the set identifier.
In an embodiment, in order to better set network slice identification information of a terminal device, referring to fig. 5, after the step of configuring the identification information for the terminal device, where the identification information identifies a scene identification of a network slice supported by the terminal device, the method further includes:
step S14, determining whether the service type changes;
step S15, after the service type is changed, determining the updating identification information corresponding to the changed service type;
step S16, configuring the update identification information for the terminal device.
Different services correspond to different service types, different service types and different network requirements, that is, the scene information corresponding to network slices is different, the service types are different, and the scene information corresponding to the network slices is different, for example, an information service is provided to a user, so that the requirement on time delay is not high, and the information service can correspond to a high-delay network slice scene; and if the video service is, the corresponding delay requirement is high, and the low-delay network slice scene can be corresponded to.
Specifically, the service division includes: information service, entertainment service, message service, and mobile commerce service; the information service provides news, weather, sports, tourism, finance and other information to the user according to different interests and requirements of the user. The mobile data service of the information class is that an operator or a service provider provides information and information services to users based on Short Message Service (SMS), Multimedia Message Service (MMS) and Location Based Service (LBS) technologies.
The entertainment services mainly comprise ring tones, icons, music, chatting, friend-making reading, websites, APP and the like.
The message service includes Short Message Service (SMS), Multimedia Message Service (MMS), IM (instant message), and E-mail.
Mobile commerce services include micropayments, online transactions, and the like.
Of course, the service types can be divided into other different service types according to different selected division requirements. When the service types are different, the requirements for the networks are different, after the service types are changed, configuration switching needs to be performed in a network slice configured by the terminal, or external identification information needs to be replaced, updated identification information corresponding to the currently required service types is found, and configuration is completed by updating the identification information, so that identification information configuration can be flexibly selected according to different service types, the accuracy of accessing different services to the networks is improved, the reliability of completing the terminal service is improved, configuration is completed according to requirements, the configuration updating process is completed through communication with an after-sale maintenance system of an operator or the terminal, and the configuration is completed through firmware upgrading or software upgrading. It can be understood that a plurality of identification information can be configured in advance, and switching can be selected in different identification information according to different support of service types without performing a configuration process every time.
The network slice configuration of the corresponding Subscriber Identity Module (SIM) card may be similar, and the subscriber identity module may be selectively switched, but needs to be configured in advance, and select the identification information matching the service type from the subscriber identity module, and the configuration may not be continuously adjusted after use, or may support the configuration, and needs to re-adjust the configuration for the operator service of the card.
The triggering of the network access operation can be triggered by the opening of a new application or the opening of a new function requirement when the terminal is started or after the terminal is started; or the triggering of the network access operation started through a virtual key provided by the terminal equipment. The network access operation includes an operation of initiating an access network, or a network access switching or changing operation triggered by a service change, which belongs to the network access operation, and of course, also includes other applicable network access operations related to network re-access, network initial access, network switching or network change access, etc. When the network access operation is triggered, in response to the network access operation of the terminal equipment, a processor of the terminal equipment acquires second network slice information from an SIM card, acquires first network slice information from a network slice of the terminal, and further acquires the first network slice information and the second network slice information, wherein the first network slice information is network slice information supported by the terminal equipment, and the second network slice information is network slice information supported by a user identification card in the terminal. In network access, the network slice information supported by the terminal equipment and the network slice information supported by the subscriber identity card used in the terminal, which may be a SIM card, e.g. a 5G card, are considered. The user realizes the construction of the mobile network interconnected with the outside by putting the 5G card in the terminal. Network slices are configured on the 5G card and the terminal equipment side, network access is achieved through the network slices, and data access or connection with the outside is achieved.
Step S20, selecting a corresponding network slice access network according to the first network slice information and the second network slice information.
After the first network slice information and the second network slice information are obtained and the network slice information respectively supported by the terminal equipment and the subscriber identity module card is obtained, one network slice supported by the terminal equipment and the subscriber identity module card is selected to complete network access, selecting a corresponding network slice access network through the first network slice information and the second network slice information, selecting a network slice access network with a target, selecting network slice when making network access, completing network access according to configuration parameters of the selected network slice after selecting the network slice, selecting the selected network slice according to the first network slice information and the second network slice information, rather than requiring access to multiple network slices, network resources, e.g., network IP address resources, are occupied, affecting the operation of the terminal device's traffic. The configuration parameters are set according to the function of the network slice or the network performance, or default parameters, for example, including bandwidth, latency parameters, etc.
The network access mode of the embodiment needs to select the network slice to access the network according to the terminal device and the network slice information supported by the subscriber identity module card used by the terminal device, instead of accessing a plurality of network slices at present, and occupies IP resources, the improved network access mode does not access a plurality of network slices, and selectively accesses the network slices, thereby reducing the problem of network resource occupation, achieving accurate matching of network slice access, and improving the resource utilization rate.
In an embodiment of the present application, referring to fig. 6, the step of selecting a corresponding access parameter access network according to the first network slice information and the second network slice information includes:
step S21, determining a currently supported network slice according to the first network slice information and the second network slice information;
and step S22, selecting a corresponding network slice access network from the currently supported network slices.
After the network slice information supported by the terminal device and the user identification card is acquired, the currently supported network slice needs to be determined according to the acquired first network slice information and the acquired second network slice information. And selecting a corresponding network slice from the currently determined supported network slices to access the network, wherein the supported network slices are determined according to the first network slice information and the second network slice information, and then the corresponding network slices which are in accordance with the network slices are selected from the supported network slices to complete the service operation.
In the embodiment, the currently supported king network slices are matched through the network slice information of the terminal equipment and the subscriber identity module card, namely the currently accessible network slices are matched, and the network slices are accessed through selecting the corresponding network slices from the supported network slices, so that the network slices are accessed in a targeted manner, the phenomenon that the network slices are accessed wrongly to influence the use of network resources is avoided, and the network smoothness and accuracy are improved.
In an embodiment, referring to fig. 7, the step of determining the currently supported network slice according to the first network slice information and the second network slice information comprises:
step S211, comparing the first network slice information with the second network slice information;
step S212, determining whether intersection information of the network slice information exists between the first network slice information and the second network slice information according to the comparison result;
and step S213, when the intersection information exists, determining the currently supported network slice according to the intersection information.
The network slice information supported by the terminal device and the network slice information supported by the subscriber identity module may or may not overlap, and are different according to a specific configuration process. After first network slice information and second network slice information are obtained, the first network slice information and the second network slice information are compared to obtain a comparison result, the comparison result comprises whether intersection information exists between the first network slice information and the second network slice information or not, intersection exists, the same network slices supported by the terminal equipment and the user identification card exist, the currently supported network slices are selected through the first network slice information and the second network slice information, the number of the determined currently supported network slices is reduced, the number of the currently supported network slices is reduced compared with the number of all currently accessed network slices, and the setting of the same IP and the redundant access of the network slices can be reduced.
In one embodiment, when the intersection information does not exist, the currently supported network slice is determined according to the first network slice information. For example, if the terminal does not support the subscriber identity module card network slice, the network slice supported by the terminal is mainly used, and according to the network slice currently supported by the terminal, the network slice is selected from the network slices supported by the terminal according to the scene to access the network and report the network slice to the network.
In this embodiment, the currently supported network slices are determined through the intersection of the first network slice information and the second network slice information, and then the network slices are selected from the currently supported network slices to be accessed, so that the number of the accessed network slices is reduced, the situation of network resource occupation is reduced, and the utilization rate of the network resources is improved. By selecting the scene information of the network access, the network access matching is more in line with the service requirement, and the smoothness of service operation is improved.
In an embodiment, referring to fig. 8, when there are a plurality of the current supported network slices, the step of selecting a corresponding network slice access network from the current supported network slices includes:
step S201, determining a service type corresponding to the operation of network access;
step S202, selecting a network slice access network corresponding to the service type from a plurality of network slices currently supported.
The network slices simultaneously supported by the terminal equipment and the user identification card have a plurality of conditions, and a plurality of determined intersected network slices need to select one network slice from the intersection information and access the network through the network slice, so that more accuracy can be achieved. The process of selecting one of the supported network slices may be to select one network slice from the plurality of network slices through the service type, access the network by using the selected network slice, select the network slice matched with the service type and better supporting the service from the plurality of network slices through the service type, and access the network, thereby improving the speed and efficiency of service processing. The service type and the scene identification information set by the network slice have a corresponding relation, selection is made through the corresponding relation, and one network slice supporting service operation is selected through matching the scene information and the service type, so that the accuracy of determining the network slice is improved. In an embodiment, the service type and the characteristic information of the network slice may be combined, for example, the characteristic information of the network slice is the service type of the support information, and the network slice is more reasonably and accurately selected by combining and matching the characteristic information of the network and the service type.
In the embodiment, when a plurality of currently supported network slices exist, one network slice is selected from a plurality of network slice scene information according to the service type, the selected network slice is matched with the access network, and one network slice is accurately selected to be accessed to the network, so that the accurate matching and reasonable utilization of the network are realized, the utilization rate is improved, and the conflict and occupation are avoided.
In an embodiment, referring to fig. 9, after the step of selecting a corresponding network slice access network according to the first network slice information and the second network slice information, the method further includes:
step S30, responding to the service request, judging whether the current accessed network slice accords with the service request;
step S40, when not satisfied, obtaining a service request identifier, and determining a target network slice conforming to the service request according to the service request identifier, the first network slice information and the second network slice information;
and step S50, accessing the target network slice.
After determining that the network access parameter is accessed to the network, a service request is received, for example, information transmission of instant messaging, or information service type, business application type and the like, if the accessed network does not meet service requirements, a service request identifier is obtained, a target network slice meeting the service request is determined according to the service request identifier, first network slice information and second network slice information, the network slice meeting the service request is selected from network slices supported by terminal equipment and a user identification card through the service identifier to serve as the target network slice, the network is accessed through the target network slice, the network requirement of the service request is met, the processing speed of the service is improved, and the service data transmission and interaction requirement of the service request are quickly completed.
In one embodiment, when the service request is not satisfied, network slice scene information is selected from the network slice scene information supported by the terminal according to the service request to access the network, so that smooth operation of the terminal device is performed and the service processing speed is increased. It can be understood that when there is a match with the service request with the same support of the terminal device and the subscriber identity card, the matching network slice scenario information is selected to access the network.
In the embodiment, after the network is accessed, the matching degree between the network and the service is further corrected, and when the matching degree is not matched, the target network slice is selected again according to the service identifier, so that the network access requirement of the service is met, the accuracy of network access selection is improved, and the service processing speed is improved.

2) High throughput, high security, e.g., 2 for unmanned aerial vehicles, unmanned vehicles, etc
3) Improving the person-to-person communication experience of access devices, e.g. mobile phones with a device value of 3
Step 3: and (3) network access process processing:

In an embodiment of the present application, referring to fig. 11, a process for configuring network slice identification information is provided, including:
step S01, responding to the scene information setting operation of the network slice, and acquiring the device type of the terminal device;
step S02, determining the identification information of the network slice according to the device type;
step S03, configuring the identification information for the terminal device, where the identification information identifies a scene identifier of a network slice supported by the terminal device.
The scene information of the network slice corresponds to the type of the device, for example, the time delay requirements are different, the scenes are different, a high time delay scene and a low time delay scene are different, the high time delay scene and the low time delay scene are relative concepts rather than absolute concepts, and the high time delay scene and the low time delay scene can be divided by setting a time delay value. The types of the terminal equipment can be divided into mobile terminal equipment, unmanned equipment, non-mobile equipment and the like, and the different types of the terminal equipment correspond to different required scenes. For example, the type of the mobile terminal device needs a communication embodied scenario, and a scenario using APP or instant messaging application needs to set corresponding network slice identification information. After the identification information of the network slice needing to be configured is determined, the identification information is configured for the terminal equipment and configured as the identification information of the network slice supported by the current terminal equipment. Certainly, the network slice information supported by the terminal is not one-time invariant and can change along with different configured identification information, the hardware and the architecture of the terminal equipment support the change, and the network slice access is selected to optimize the network access only by setting the corresponding identification information according to the requirement when the hardware and the architecture of the terminal equipment are external.
Optionally, when the requirements of different terminal devices are different, the configured supported network slices are different, for example, a terminal network slice scene identifier is stored in NV or a partition as an identifier (named UE _ NSSAI), and the scene parameter format is as follows:
UE _ NSSAI, 1 represents eMBB, 2 represents URLLC, and 3 represents MIoT;
1) if the requirement on time delay is not high and no mobility exists, the water and electricity meter equipment stores the value as 1;
2) high throughput, high security devices such as drones, unmanned vehicles, etc. are stored as 2;
3) the person-to-person communication experience of the access equipment is improved, and the equipment such as a mobile phone is stored as 3.
For the subscriber identity module, for example, the network slice scenario identifier supported by the SIM card, for example, the addition of the EF _ NSSAI file identifier of the SIM card to the network switching scenario identifier corresponds to the following steps
1) If the requirement on time delay is not high and no mobility exists, the value of the water and electricity meter equipment is 1;
2) high throughput, high security, e.g., a device value of 2 for unmanned aerial vehicles, unmanned automobiles, etc.;
3) the person-to-person communication experience of the access equipment is improved, and the equipment value of a mobile phone and the like is 3.
The set marks 1, 2 and 3 are supported network slice information, and the marks 1, 2 and 3 of the terminal equipment are first network slice information; the SIM card is the second network slice information of the subscriber identity card. And after the operation of network access is triggered, acquiring first network slice information and second network slice information supported by the terminal according to the set identifier.

For example, the delivery of the detection data of the device may be a high latency type of traffic, not requiring real-time, with low latency requirements.
Of course, the service types can be divided into other different service types according to different selected division requirements. When the service types are different, the requirements for the networks are different, after the service types are changed, configuration switching needs to be performed in a network slice configured by the terminal, or external identification information needs to be replaced, updated identification information corresponding to the currently required service types is found, and configuration is completed by updating the identification information, so that identification information configuration can be flexibly selected according to different service types, the accuracy of accessing different services to the networks is improved, the reliability of completing the terminal service is improved, configuration is completed according to requirements, the configuration updating process is completed through communication with an after-sale maintenance system of an operator or the terminal, and the configuration is completed through firmware upgrading or software upgrading.
