Fig. 1 is a flowchart illustrating a network connection method according to an exemplary embodiment, and fig. 2 is a scene diagram illustrating a network connection method according to an exemplary embodiment; the network connection method can be used for a terminal. As shown in fig. 1, the network connection method includes the following steps 110 to 120:

in step 110, first information is generated, the first information being used to characterize the network type to which the terminal desires to connect.

In the embodiment of the disclosure, the terminal can autonomously determine the network type of the expected connection and inform the base station of the network type of the expected connection, so as to expect to access the network equipment matched with the network type.

Such as: a terminal can access a 4G core network and also can access a 5G core network, the network type expected to be connected is a 5G core network, at the moment, the terminal can send first information for representing the 5G core network to a base station, so that the base station can know that the network type expected to be accessed by the terminal is the 5G core network, at the moment, the base station can judge whether the terminal is allowed to access the 5G core network according to the actual condition of the load of the current 5G core network, and if the terminal is allowed to be allowed to access, the 5G core network equipment to be connected can be determined for the terminal, and the terminal is connected with the 5G core network equipment to be connected.

In step 120, the first information is sent to the base station, so that when the base station determines that the access of the terminal is allowed according to the first information, the network device to be connected is determined for the terminal, and the terminal is connected with the network device to be connected.

In an exemplary scenario, as shown in fig. 2, a terminal and a base station are included. The terminal can generate first information, wherein the first information is used for representing the network type of the terminal expected to be connected and sending the first information to the base station; after receiving the first information sent by the terminal, the base station judges whether the terminal is allowed to be accessed according to the first information, and if the terminal is allowed to be accessed, the base station can determine the network equipment to be connected for the terminal and connect the terminal with the network equipment to be connected.

As can be seen from the above embodiments, by generating the first information, the first information is used to characterize the network type that the terminal expects to connect, and the first information is sent to the base station, so that the base station can obtain the network type that the terminal expects to connect according to the first information, which is favorable for selecting a suitable network device for the terminal and connecting, thereby meeting the network requirement of the terminal and improving the efficiency of network connection.

In an embodiment, the network type to which the terminal in the step 110 desires to connect may include a PLMN (Public Land Mobile Network ) type and/or a core network type, and the core network type may include a 4G core network and/or a 5G core network.

In addition, PLMN type may refer to operator type, such as mobile, or telecommunications, etc.

As can be seen from the above embodiments, the network types of the desired connection used for the characterization by the first information may include PLMN types and/or core network types, and the core network types may include 4G core networks and/or 5G core networks, so that after knowing the specific network type of the desired connection of the terminal, the base station can accurately select a suitable network device for the terminal and connect the terminal, thereby improving accuracy of network connection.

Fig. 3 is a flowchart illustrating another network connection method according to an exemplary embodiment, and fig. 4 is a scene diagram illustrating another network connection method according to an exemplary embodiment; the network connection method may be used for a terminal, and on the basis of the method shown in fig. 1, when executing step 120, as shown in fig. 3, the method may include the following steps 310-320:

in step 310, when the terminal is in an initial access phase, first information is added to the request message.

In the embodiment of the disclosure, when the terminal is in the initial access stage, the terminal can inform the base station of the network type of the desired connection through a request message. The request message may be message 1, message 3, or message 5 in fig. 4.

In step 320, a request message with the first information is sent to the base station, so that the base station obtains the first information from the request message.

In the embodiment of the disclosure, after the terminal sends the first information to the base station through the request information, the base station can acquire the network type expected to be connected by the terminal according to the first information, then judge whether to allow the terminal to be accessed according to the actual situation, and if the terminal is determined to be allowed to be accessed, determine the network equipment to be connected for the terminal, and connect the terminal with the network equipment to be connected.

In an exemplary scenario, as shown in fig. 4, comprising a terminal and a base station, messages 1, 2, 3, 4 and 5 are interaction information between the terminal and the base station in an initial access phase. Wherein, in the random access flow corresponding to the initial access phase: message 1, message 3, message 5 are request information sent by the terminal to the base station; messages 2 and 4 are response information returned from the base station.

Message 1 is used for requesting random access from the base station; message 2 is used to characterize the random access response; message 3 is used to characterize the request for RRC (Radio Resource Control, radio resource control protocol) connection or RRC connection reestablishment to the base station; message 4 is used to characterize the RRC connection or RRC connection reestablishment response; message 5 is used to characterize the message informing the base station that an RRC connection has been established.

When the terminal is in the initial access stage, when the request message with the first information is sent to the base station, the following three implementation manners can be adopted:

first, adding first information into the message 1, and then sending the message 1 with the first information to a base station;

secondly, adding the first information into the message 3, and then sending the message 3 with the first information to a base station;

Third, the first information is added to the message 5, and then the message 5 with the first information is sent to the base station.

As can be seen from the above embodiments, when the terminal is in the initial access stage, the base station can be informed of the network type that the terminal expects to connect through the request message in the initial access stage, so that the base station can learn the network type that the terminal expects to connect according to the request message, and further select a suitable network device for the terminal and connect, thereby improving the practicability of network connection.

in step 510, a response message sent by the base station for indicating that access is allowed is received, where the response message includes second information, where the second information is used to characterize a network device to be connected determined by the base station for the terminal.

In the embodiment of the disclosure, as shown in fig. 4, when the request message with the first message is message 1, the response message with the second message may be message 2 or message 4; when the request message with the first message is message 3, the response message with the second message may be message 4.

After the terminal receives the response message with the second information, the base station can determine that the terminal is allowed to access according to the second information, and the base station is allowed to access the network equipment to be connected determined by the base station for the terminal.

In step 520, a connection is established with the network device to be connected according to the second information.

In an exemplary scenario, as shown in fig. 4, a terminal and a base station are included, and message 1, message 2, message 3, message 4, and message 5 are interaction information between the terminal and the base station in a random access procedure. Wherein, the message 1, the message 3 and the message 5 are request information sent to the base station by the terminal; messages 2 and 4 are response information returned from the base station.

When the terminal is in the initial access phase, the terminal can inform the base station of the network type of the desired connection through messages 1, 3 and 5 in the random access flow. The method comprises the following steps:

if the terminal sends the message 1 with the first message to the base station, the base station determines to allow the access of the terminal, and the terminal determines the network equipment to be connected, then adds the second information of the network equipment to be connected to the message 2 or the message 4, and sends the message 2 or the message 4 with the second information to the terminal, so that the terminal can know the network equipment to be connected determined by the base station for the terminal from the message 2 or the message 4;

If the terminal sends the message 3 with the first message to the base station, the base station determines to allow the access of the terminal, and the terminal determines the network equipment to be connected, then adds the second information of the network equipment to be connected to the message 4, and sends the message 4 with the second information to the terminal, so that the terminal can know the network equipment to be connected determined by the base station for the terminal from the message 4;

if the terminal sends the message 5 with the first message to the base station, the base station and the message 4 allow the terminal to access, at this time, the base station determines the network device to be connected for the terminal, and connects the terminal with the network device to be connected.

As can be seen from the above embodiments, by receiving a response message sent by a base station and used for indicating permission of access, the response message includes second information, where the second information is used to characterize a network device to be connected determined by the base station for a terminal, and connection is established with the network device to be connected according to the second information, so that efficiency of network connection is improved.
