A method for determining a network standard in a wireless communications network, comprising: receiving (S201, S502, S602, S702), by an access point device, at least one network standard configuration request message sent by at least one terminal device, wherein the at least one network standard configuration request message indicates a network standard that needs to be used by the at least one terminal device; characterized in that the method further comprises: determining (S202, S503, S603, S703, S705), by the access point device according to the at least one network standard configuration request message, a same network standard that needs to be used by all or some of the at least one terminal device, as a target network standard; after determining (S202, S503, S603, S703, S705) the target network standard, configuring, by the access point device, the target network standard according to a configuration file, wherein the configuration file is used to configure the target network standard; and sending (S203, S505, S606, S707), by the access point device, a network standard trigger message to the all or some of the at least one terminal device, wherein the network standard trigger message indicates that the target network standard has already been configured by the access point device. receiving (S201, S502, S602, S702), by an access point device, at least one network standard configuration request message sent by at least one terminal device, wherein the at least one network standard configuration request message indicates a network standard that needs to be used by the at least one terminal device; characterized in that the method further comprises: determining (S202, S503, S603, S703, S705), by the access point device according to the at least one network standard configuration request message, a same network standard that needs to be used by all or some of the at least one terminal device, as a target network standard; after determining (S202, S503, S603, S703, S705) the target network standard, configuring, by the access point device, the target network standard according to a configuration file, wherein the configuration file is used to configure the target network standard; and sending (S203, S505, S606, S707), by the access point device, a network standard trigger message to the all or some of the at least one terminal device, wherein the network standard trigger message indicates that the target network standard has already been configured by the access point device. determining (S202, S503, S603, S703, S705), by the access point device according to the at least one network standard configuration request message, a same network standard that needs to be used by all or some of the at least one terminal device, as a target network standard; after determining (S202, S503, S603, S703, S705) the target network standard, configuring, by the access point device, the target network standard according to a configuration file, wherein the configuration file is used to configure the target network standard; and sending (S203, S505, S606, S707), by the access point device, a network standard trigger message to the all or some of the at least one terminal device, wherein the network standard trigger message indicates that the target network standard has already been configured by the access point device.
