A method for paging between neighbor awareness networking, NAN, devices, comprising: sending, by a first NAN device, a first paging message in a first window, wherein the first paging message carries first service information of the first NAN device, and the first service information is used to describe a service that needs to be performed by the first NAN device; receiving, by the first NAN device, a paging response message sent by a second NAN device that meets the first service information, wherein the paging response message is used to indicate that data transmission needs to be performed between the first NAN device and the second NAN device; and determining, by the first NAN device according to the paging response message, whether the first NAN device is to perform data transmission with the second NAN device; wherein the paging response message is a query message, and the query message is used to query whether the first NAN device needs to send data to the second NAN device; and the determining, by the first NAN device according to the paging response message, whether the first NAN device is to perform data transmission with the second NAN device comprises: determining, by the first NAN device according to the query message, whether the first NAN device is to send data to the second NAN device; wherein, after receiving the query message sent by the second NAN device, the first NAN device determines, according to the query message, whether the first NAN device buffers data to be sent to the second NAN device, and if the first NAN device buffers data to be sent to the second NAN device, the first NAN device determines to send the buffered data to the second NAN device and if the first NAN device buffers no data to be sent to the second NAN device, the first NAN device determines not to send the buffered data to the second NAN device; or wherein the paging response message is a transmission indication message, and the transmission indication message is used to indicate that the second NAN device needs to send data to the first NAN device; and the determining, by the first NAN device according to the paging response message, whether the first NAN device is to perform data transmission with the second NAN device comprises: determining, by the first NAN device according to the transmission indication message, whether the first NAN device is to receive data to be sent by the second NAN device; wherein, after receiving the transmission indication message sent by the second NAN device, the first NAN device determines, according to the transmission indication message, whether to receive the data that is to be sent by the second NAN device. sending, by a first NAN device, a first paging message in a first window, wherein the first paging message carries first service information of the first NAN device, and the first service information is used to describe a service that needs to be performed by the first NAN device; receiving, by the first NAN device, a paging response message sent by a second NAN device that meets the first service information, wherein the paging response message is used to indicate that data transmission needs to be performed between the first NAN device and the second NAN device; and determining, by the first NAN device according to the paging response message, whether the first NAN device is to perform data transmission with the second NAN device; wherein the paging response message is a query message, and the query message is used to query whether the first NAN device needs to send data to the second NAN device; and the determining, by the first NAN device according to the paging response message, whether the first NAN device is to perform data transmission with the second NAN device comprises: determining, by the first NAN device according to the query message, whether the first NAN device is to send data to the second NAN device; wherein, after receiving the query message sent by the second NAN device, the first NAN device determines, according to the query message, whether the first NAN device buffers data to be sent to the second NAN device, and if the first NAN device buffers data to be sent to the second NAN device, the first NAN device determines to send the buffered data to the second NAN device and if the first NAN device buffers no data to be sent to the second NAN device, the first NAN device determines not to send the buffered data to the second NAN device; or wherein the paging response message is a transmission indication message, and the transmission indication message is used to indicate that the second NAN device needs to send data to the first NAN device; and the determining, by the first NAN device according to the paging response message, whether the first NAN device is to perform data transmission with the second NAN device comprises: determining, by the first NAN device according to the transmission indication message, whether the first NAN device is to receive data to be sent by the second NAN device; wherein, after receiving the transmission indication message sent by the second NAN device, the first NAN device determines, according to the transmission indication message, whether to receive the data that is to be sent by the second NAN device.
