Fig. 1 is a flow chart illustrating a network access method according to an example embodiment, and fig. 2 is a scene diagram illustrating a network access method according to an example embodiment; the network access method may be used for a core network device, the core network device being connected to at least one base station. As shown in fig. 1, the network access method includes the following steps 110 and 120:

in step 110, first information is generated, where the first information is used to characterize network service contents that can be supported by the core network device.

In the embodiment of the disclosure, the core network device may be connected to one or more base stations, and notify each base station connected with the network service content that can be supported by the core network device, so that after each base station learns the network service content that can be supported by the core network device, each base station notifies terminals within a coverage range of the base stations of the network service content that can be supported by the core network device, and the terminals can determine the base stations and the core network device that need to be accessed by the terminals.

Such as: the core network device is a 5G core network device, the first information generated by the 5G core network device is used for representing service contents which can be provided for a user by the 5G core network device, and the service contents which can be provided for the user by the 5G core network device are sent to each base station connected with the 5G core network device, so that after each station acquires the network service contents which can be supported by the 5G core network device, the network service contents which can be supported by the 5G core network device can be notified to terminals in the coverage range of the base stations, and the terminals can enjoy the network service which can be supported by the 5G core network device after being accessed into the 5G core network device.

In step 120, the first information is sent to each connected base station, so that each base station receives the first information and then sends the first information to the terminals within its coverage area.

In an exemplary scenario, as shown in fig. 2, a 4G core network device, a 5G core network device, a base station 1, a base station 2, and a terminal are included. The 4G core network device is respectively connected with the base station 1 and the base station 2, the 5G core network device is only connected with the base station 2, and the terminal 1 is respectively located in the coverage range of the base station 1 and the base station 2.

The 4G core network equipment generates a first message, the first message is used for representing network service contents which can be supported by the 4G core network equipment, and the first message is respectively sent to the base station 1 and the base station 2.

The 5G core network device also generates a first message, where the first message is used to characterize the network service content that the 5G core network device can support, and sends the first message to the base station 2.

After receiving a first message sent by a 4G core network device and used for representing network service contents that the 4G core network device can support, a base station 1 sends the first message sent by the 5G core network device to a terminal 1 within its coverage area.

The base station 2 receives the first message sent by the 4G core network device and used for representing the network service content that the 4G core network device can support, and the first message sent by the 5G core network device and used for representing the network service content that the 5G core network device can support, and sends each first message to the terminal 1 within its coverage area.

Since the terminal 1 is respectively located in the coverage areas of the base station 1 and the base station 2, the terminal 1 can receive a first message sent by the base station 1 and used for representing network service contents which can be supported by 4G core network equipment; and a first message sent by the base station 2 and used for characterizing the network service content that can be supported by the 4G core network device and a first message sent by the 5G core network device and used for characterizing the network service content that can be supported by the 5G core network device can also be received, at this time, the terminal 1 may have the following three network access options:

(1) access base station 1 and 4G core network equipment

(2) Access base station 2 and 4G core network equipment

(3) Access base station 2 and 5G core network equipment

The terminal 1 will select a suitable base station and core network device from the above (1) - (3) according to its own needs, and access the selected base station and core network device.

According to the embodiment, the first information used for representing the network service content which can be supported by the core network equipment is generated, and is sent to the connected base stations, so that the base stations respectively send the first information to the terminal within the coverage range of the base stations after receiving the first information, the terminal can timely know the network service content which can be supported by the core network equipment connected with the base stations, and accordingly, the appropriate base stations and the core network equipment are selected for access, the accuracy of network access is improved, and the efficiency of network access is also improved.

In an embodiment, the core network device in step 110 may be a 4G core network device, and may also be a 5G core network device.

In the embodiment of the present disclosure, regardless of the 4G core network device or the 5G core network device, the first message for representing the network service content that can be supported by the device itself may be sent to each connected base station.

If the core network equipment is 4G core network equipment, the 4G core network equipment generates first information, the first information is used for representing service contents which can be provided for users by the 4G core network equipment, and the first information is sent to each connected base station, so that after each base station receives the first information, each base station sends the first information to a terminal in the coverage range of the base station.

If the core network equipment is 5G core network equipment, the 5G core network equipment generates first information, the first information is used for representing service contents which can be provided for users by the 5G core network equipment, and the first information is sent to each connected base station, so that after each base station receives the first information, each base station sends the first information to a terminal within the coverage range of the base station.

The service content that the 5G core network device can provide for the user may be different from the service content that the 4G core network device can provide for the user, such as: quality of service (QoS), security (security), network slicing (network slicing), support for dual connectivity (dual for connectivity), mobility (mobility), support for edge computing (edge computing), and the like may be different.

As can be seen from the above embodiments, regardless of whether the 4G core network device or the 5G core network device generates the first information for representing the network service content that can be supported by itself, and sends the first information to each connected base station, so that each base station receives the first information and then sends the first information to the terminal within its coverage area, and the terminal can timely know the network service content that can be supported by the 4G core network device and/or the 5G core network device connected to the base station, so as to select a suitable base station and core network device for access, which can meet the requirements of a 5G terminal that can access the 4G core network and can also access the 5G core network, and select a suitable base station and core network device, thereby expanding the application range of network access and improving the reliability of network access.

In an embodiment, the first information is transmitted to each connected base station in the step 120, but the following implementations (1-1) and (1-2) may be adopted:

(1-1) adding the first information to a first Next Generation Application Protocol (NGAP) signaling;

and (1-2) sending the first NGAP signaling to each connected base station through an interface between the core network equipment and the base station, so that each base station acquires first information from the first NGAP signaling.

In the embodiment of the disclosure, the core network device and the base station may communicate with each other through NGAP signaling.

It can be seen from the above embodiments that, by adding the first information to the first NGAP signaling, the first NGAP signaling is sent to each connected base station through an interface between the core network device and the base station, so that each base station acquires the first information from the first NGAP signaling, thereby implementing that the core network device sends network service content that can be supported by itself through the NGAP signaling, and further improving reliability of transmission of the first information.

Fig. 3 is a flow diagram illustrating another network access method that may be used for a core network device connected to at least one base station according to an example embodiment. Based on the method shown in fig. 1, as shown in fig. 3, the network access method further includes the following steps 310 and 320:

in step 310, when the network service content that the core network device can support changes, second information is generated, and the second information is used for characterizing the changed network service content.

In the embodiment of the present disclosure, if a network service or a service characteristic that can be supported by a core network device changes, for example: the content of the corresponding web service may also change by adding web services, reducing web services, changing service characteristics, etc. The core network device may be a 4G core network device, and may also be a 5G core network device.

Such as: a new network service is added to the network services that can be supported by the 4G core network device, and the 4G core network device generates second information, where the second information is used to represent the changed network service content of the 4G core network device, that is, the changed network service content includes content corresponding to the new network service.

For another example: a new network service is added to the network services that can be supported by the 5G core network device, and the 5G core network device generates second information, where the second information is used for the 5G core network device to represent the changed network service content, that is, the changed network service content includes content corresponding to the new network service.

In step 320, the second information is sent to each connected base station, so that each base station receives the second information and then sends the second information to the terminals within its coverage area.

In the embodiment of the present disclosure, the core network device notifies each base station connected to the changed network service content, so that each base station learns the changed network service content of the core network device, and notifies the changed network service content of the core network device to terminals in the coverage area of the base stations, which is convenient for the terminals to determine the base stations and the core network devices to be accessed.

It can be seen from the above embodiments that, when the network service content that can be supported by the core network device changes, second information needs to be generated, where the second information is used to characterize the changed network service content, and send the second information to each connected base station, so that each base station, after receiving the second information, sends the second information to a terminal within its coverage area, so that the terminal can timely learn the changed network service content of the core network device connected to the base station, and select another suitable base station and core network device, thereby improving the service level provided by the core network device for the terminal, further satisfying the autonomous requirement of the terminal, and improving the practicability of network access.

In an embodiment, the above step 320 may adopt, but is not limited to, the following implementations (2-1) and (2-2) when sending the second information to the connected base stations:

(2-1) adding the second information to the second NGAP signaling;

and (2-2) sending the second NGAP signaling to each connected base station through an interface between the core network equipment and the base station, so that each base station acquires second information from the second NGAP signaling.

It can be seen from the above embodiments that, by adding the second information to the second NGAP signaling, the second NGAP signaling is sent to each connected base station through the interface between the core network device and the base station, so that each base station can obtain the second information from the second NGAP signaling after receiving the second NGAP signaling, thereby improving the reliability of the transmission of the second information.

Fig. 4 is a flowchart illustrating a network access method according to an exemplary embodiment, where the network access method may be used for a base station, and the base station is connected to at least one core network device, where the at least one core network device may include a 4G core network device and/or a 5G core network device, for example, the base station 1 in fig. 2 is connected to only the 5G core network device, and the base station 2 is connected to the 4G core network device and the 5G core network device, respectively. As shown in fig. 4, the network access method includes the following steps 410 and 420:

in step 410, first information sent by each connected core network device is received, where the first information is used to characterize network service contents that the core network device can support.

In the embodiment of the present disclosure, if the core network device is a 4G core network device, the first information sent by the 4G core network device is used to represent network service content that the 4G core network device can support; if the core network device is a 5G core network device, the first information sent by the 5G core network device is used to represent the network service content that the 5G core network device can support.

In step 420, each first message is sent to the terminal within the coverage area of the terminal, so that the terminal determines the base station and the core network device which the terminal needs to access.

For example, the base station 1 in fig. 2 receives the first message sent by the 4G core network device, and sends the first message sent by the 4G core network device to the terminal 1 in its coverage area.

For another example: after receiving the first message sent by the 4G core network device and the first message sent by the 5G core network device, the base station 2 in fig. 2 sends both the first message sent by the 4G core network device and the first message sent by the 5G core network device to the terminal 1 within its coverage area.

As can be seen from the above embodiments, by receiving the first information sent by each connected core network device, where the first information is used to represent network service content that the core network device can support, and sending each first information to the terminal within its coverage, the terminal can timely know the network service content that the core network device connected to the base station can support, so as to select a suitable base station and core network device for access, thereby improving accuracy of network access and also improving efficiency of network access.

In an embodiment, when each first information is sent to the terminal within the coverage area of the terminal in step 420, the following implementations (3-1) and (3-2) may be adopted, but are not limited to:

(3-1) adding respective first information to the first system message;

and (3-2) broadcasting the first system message so that the terminal acquires each first information from the first system message.

As can be seen from the above embodiments, by adding each piece of first information to the first system message and broadcasting the first system message, the terminal acquires each piece of first information from the first system message, thereby implementing that the base station broadcasts, through the system message, network service content that can be supported by the core network device to which the base station is connected, and also improving the reliability of transmission of the first information.

Fig. 5 is a flowchart illustrating another network access method according to an exemplary embodiment, where the network access method may be used for a base station, and the base station is connected to at least one core network device, where the at least one core network device may include a 4G core network device and/or a 5G core network device, for example, the base station 1 in fig. 2 is connected to only the 5G core network device, and the base station 2 is connected to the 4G core network device and the 5G core network device, respectively. Based on the method shown in fig. 4, as shown in fig. 5, the network access method further includes the following steps 510 and 520:

in step 510, second information sent by each connected core network device is received, where the second information is used to characterize the changed network service content.

In the embodiment of the present disclosure, if the core network device is a 4G core network device, the second information sent by the 4G core network device is used to represent the network service content after the 4G core network device is changed; if the core network device is a 5G core network device, the second information sent by the 5G core network device is used for the network service content after the 5G core network device changes.

In step 520, each second message is sent to the terminal within the coverage area of the terminal, so that the terminal determines the base station and the core network device which the terminal needs to access.

For example, after receiving the second information sent by the 4G core network device, the base station 1 in fig. 2 sends the second information to the terminal 1 within its coverage area.

For another example: after receiving the second information sent by the 4G core network device and the second information sent by the 5G core network device, the base station 2 in fig. 2 sends each second information to the terminal 1 within its coverage area.

It can be seen from the above embodiments that, when the network service content that the core network device can support changes, the base station can receive the second information generated by the core network device, where the second information is used to characterize the changed network service content, and send each second information to the terminal within its coverage, so that the terminal can timely know the changed network service content of the core network device connected to the base station, and select another suitable base station and core network device, thereby improving the service level provided by the core network device for the terminal, further meeting the autonomous requirement of the terminal, and improving the practicability of network access.

In an embodiment, when each second information is sent to the terminal within the coverage area of the terminal in the step 520, the following implementations (4-1) and (4-2) may be adopted, but are not limited to:

(4-1) adding respective second information to the first system message;

and (4-2) broadcasting the second system message so that the terminal acquires each piece of second information from the second system message.

As can be seen from the above embodiments, by adding each piece of second information to the first system message and broadcasting the second system message, the terminal acquires each piece of second information from the second system message, thereby implementing that the base station broadcasts the changed network service content of the core network device connected to the base station through the system message, and also improving the reliability of transmission of the second information.

As shown in fig. 6, the network access method includes the following steps 610 and 630:

in step 610, first information of each core network device connected to any base station is received, where the first information is used to characterize network service contents that the core network device can support.

In step 620, the base station and the core network device that need to be accessed are determined according to the first information sent by each base station.

In step 630, the determined base station and core network device are accessed.

Such as: the terminal 1 in fig. 2 may access a 4G core network or a 5G core network, and after receiving the first information of the 4G core network device sent by the base station 1, the first information of the 4G core network device sent by the base station 2, and the first information of the 5G core network device, the terminal 1 determines that the base station and the core network device that need to be accessed by itself are: base stations 2 and 5G core network devices, and access the base stations 2 and 5G core network devices.

It can be seen from the above embodiments that, by receiving the respective first information of each core network device connected to any base station and sent by the base station, where the first information is used to characterize the network service content that the core network device can support, determining the base station and the core network device that need to be accessed by the terminal according to each first information sent by each base station, and accessing the determined base station and core network device, the terminal can select the base station and the core network device that need to be accessed autonomously according to the network service content that the core network device connected to the base station can support, thereby improving the accuracy of network access and also improving the efficiency of network access.

Based on the method shown in fig. 6, as shown in fig. 7, the network access method further includes the following steps 710 and 730:

in step 710, second information of each core network device connected to any base station and sent by the base station is received, where the second information is used to characterize the changed network service content.

In step 720, another base station and core network device that need to be accessed by itself are determined according to each second information sent by each base station.

In step 730, the determined another base station and core network device are accessed.

Such as: after the terminal 1 accesses the base stations 2 and 5G core network devices, and after receiving the second information of the 4G core network device sent by the base station 1, the second information of the 4G core network device sent by the base station 2, and the second information of the 4G core network device and the second information of the 5G core network device sent by the base station 2, it is found that the base stations 2 and 5G core network devices cannot meet their own requirements, and at this time, it can be determined that the base stations and the core network devices that need to be accessed by themselves are: base station 1 and 4G core network equipment, and access to the base station 1 and 4G core network equipment.

It can be seen from the above embodiments that, by receiving the respective second information of each core network device connected to any base station and sent by the base station, where the second information is used to characterize the changed network service content, according to each second information sent by each base station, another base station and core network device that the base station needs to access to itself are determined, and the determined another base station and core network device are accessed to thereby improve the service level provided by the core network device for the terminal, also meet the autonomous requirement of the terminal, and improve the practicability of network access.
