Fig. 1 is a flow diagram 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 may be used for a terminal. As shown in fig. 1, the network connection method includes the following steps 110 and 120:

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

In the embodiment of the disclosure, the terminal may autonomously determine the network type of the desired connection and inform the base station of the network type of the desired connection, so as to desire to access the network device matched with the network type.

Such as: a terminal can access both a 4G core network and a 5G core network, the type of the network to which the terminal desires to connect is a 5G core network, and at this time, the terminal can send first information for characterizing the 5G core network to the base station, so that the base station can know that the type of the network to which the terminal desires to access is the 5G core network, and at this time, the base station can judge whether to allow the terminal 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 determined to be allowed to access, the terminal can determine 5G core network equipment to be connected, and connect the terminal 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 base station determines a network device to be connected for the terminal, and connects the terminal 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, the first information is used for representing the network type which the terminal expects to be connected with, and the first information is sent to the base station; after receiving the first information sent by the terminal, the base station may determine whether to allow the terminal to access according to the first information, and if it is determined that the terminal is allowed to access, may determine a network device to be connected for the terminal, and connect the terminal with the network device to be connected.

According to the embodiment, the first information is generated and used for representing the network type expected to be connected by the terminal, and the first information is sent to the base station, so that the base station can know the network type expected to be connected by the terminal according to the first information, and is favorable for selecting proper network equipment for the terminal to connect, thereby meeting the network requirement of the terminal and improving the network connection efficiency.

In an embodiment, the Network type to which the terminal desires to connect in step 110 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, the PLMN type may refer to an operator type, such as mobile, or telecommunications, or unicom, etc.

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

Fig. 3 is a flowchart illustrating another network connection method according to an example embodiment, and fig. 4 is a scene diagram illustrating another network connection method according to an example embodiment; the network connection method may be applied to a terminal, and based on the method shown in fig. 1, when step 120 is executed, as shown in fig. 3, the method may include the following steps 310 and 320:

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

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

In step 320, the request message with the first information is sent to the base station, so that the base station acquires 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 may obtain the network type to which the terminal is expected to connect according to the first information, then judge whether to allow the terminal to access according to an actual situation, determine the network device to be connected for the terminal if the terminal is determined to be allowed to access, and connect the terminal with the network device to be connected.

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 mutual information between the terminal and the base station in an initial access phase. Wherein, in the random access process corresponding to the initial access stage: message 1, message 3 and message 5 are request information sent by the terminal to the base station; message 2 and message 4 are response messages returned by the base station.

Message 1 is used to request random access to the base station; message 2 is used to characterize the random access response; the message 3 is used for representing a 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; the message 5 is used for characterizing to inform the base station that the RRC connection is established.

When the terminal is in the initial access phase, and when the request message with the first information is sent to the base station, there may be the following three implementation manners:

firstly, adding first information into a 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 the base station;

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

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

Fig. 5 is a flowchart illustrating another network connection method according to an exemplary embodiment, where the network connection method may be used for a terminal, and on the basis of the method illustrated in fig. 3, the request message is a message 1 or a message 3 in a random access procedure, as illustrated in fig. 5, the network connection method may further include the following steps 510 and 520:

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

In the embodiment of the present 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 allowed access base station is the network equipment to be connected determined by 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 mutual 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 by the terminal to the base station; message 2 and message 4 are response messages returned by the base station.

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

if the terminal sends the message 1 with the first message to the base station, the base station determines that the terminal is allowed to access, and the terminal determines the network equipment to be connected, the second information of the network equipment to be connected is added to the message 2 or the message 4, and the message 2 or the message 4 with the second information is sent 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 that the terminal is allowed to access, and after the terminal determines the network equipment to be connected, the second information of the network equipment to be connected is added to the message 4, and the message 4 with the second information is sent to the terminal, so that the terminal can acquire 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 access of the terminal is allowed in the message 4, and the base station determines the network equipment to be connected for the terminal and connects the terminal with the network equipment to be connected.

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

Fig. 6 is a flowchart illustrating another network connection method according to an example embodiment, and fig. 7 is a scene diagram illustrating another network connection method according to an example embodiment; the network connection method may be applied to a terminal, and based on the method shown in fig. 1, when step 120 is executed, as shown in fig. 6, the method may include the following steps 610 and 620:

in step 610, when the terminal performs measurement report during moving, the first information is added to the measurement report.

In the embodiment of the disclosure, when the terminal performs measurement report during moving, the terminal may inform the base station of the network type of the desired connection through the measurement report.

In addition, when the terminal performs measurement reporting in the moving process, the terminal can also inform the target base station expected to be switched to the source base station currently serving the terminal, so that after the source base station learns the network type expected to be connected by the terminal and the target base station expected to be switched, the source base station can inform the target base station of the network type expected to be connected by the terminal, and the target base station can better provide the network service expected by the terminal for the terminal.

In step 620, the measurement report with the first information is sent to the base station, so that the base station acquires the first information from the measurement report.

In the embodiment of the present disclosure, after acquiring the first information from the measurement report, the base station may obtain the network type to which the terminal is expected to be connected according to the first information, so that the base station may determine whether to allow the terminal to access according to an actual situation, and determine the network device to be connected for the terminal and connect the terminal with the network device to be connected if it is determined that the terminal is allowed to access.

In an exemplary scenario, as shown in fig. 7, the ue includes a terminal and a base station, and the measurement configuration parameter and the measurement report are measured, and the handover request message is interactive information between the terminal and the base station during a moving process.

When the terminal needs the measurement report, the terminal can add the first information to the measurement report and send the measurement report with the first information to the base station, so as to report the network type which the terminal desires to connect with to the base station.

Or, when the measurement report sent by the terminal further includes a target base station to which the terminal desires to switch, the source base station may also add the first information to the handover request message, and send the handover request message with the first information to the target base station, so as to inform the target base station of the network type to which the source base station desires to connect.

It can be seen from the above embodiments that, when the terminal performs measurement reporting during a moving process, the first information may be added to the measurement report, and the measurement report with the first information is sent to the base station, so that the base station may know a network type to which the terminal desires to connect according to the measurement report, and further select a suitable network device for the terminal to connect, thereby improving network connection efficiency.

In step 820, when it is determined that the access of the terminal is allowed according to the first information, a network device to be connected is determined for the terminal.
