Abstract: This application provides a data transmission method and communications devices. In some implementations, a first device instructs a second device to stop sending data of an application to the first device, receives from the second device first indication information indicating a sequence number of data that is of the application and that has been received by the second device from the first device, and sends to the second device second indication information indicating a sequence number of data that is of the application and that has been received by the first device from the second device. After a connection between the terminal device and a second server is established, the first and second indication information are used to transmit the data of the application through the connection.

Abstract: A paging method and apparatus are provided to simplify a prior-art paging process. The method includes: receiving, by an access device, downlink data, where the downlink data includes a first identifier of a terminal; determining a paging identifier based on the first identifier; and sending, by the access device, a paging message to the terminal, where the paging message carries the paging identifier. After the access device receives the downlink data, the access device can initiate the paging process without using a control plane network element device. The advantages of the innovative paging methods disclosed herein include reduced signaling, shortened signaling transmission, and simplified paging process.

Abstract: A network device obtains, from a transaction queue, a plurality of transactions that do not conflict with each other, and performs reverse shallow copying in parallel for the transactions that do not conflict, to generate a plurality of temporary trees corresponding to the plurality of transactions. Because the plurality of transactions does not conflict with each other, processing the transactions in parallel can ensure accurate and proper transaction processing. In addition, generating the temporary trees in a reverse shallow copying manner can effectively reduce consumption of time and memory. Further, processing of the plurality of transactions is implemented by merging the plurality of temporary trees.

Abstract: An interaction method in a call and a device, where the method includes displaying a voice assistant icon on a call screen of the wearable device when a phone number of a communication peer device is a service number converting received voice information into a dual tone multi frequency (DTMF) tone when the voice assistant icon is activated, and sending the DTMF tone to the communication peer device. Therefore, in a process of making or answering a service call using the wearable device, under a specific trigger condition, voice information of a user is converted into a DTMF tone to be sent to the communication peer device. In this way, when the user needs to enter a digit or a symbol in a call process, it can be ensured that the user enters correct information, and user experience is improved.
