Abstract: Example communication methods and apparatus in a wireless network are described. One example communication method includes establishing dual connections to a first access network device and a second access network device by a terminal device. A connection that is between the terminal device and the first access network device and that is included in the dual connections is a radio resource control (RRC) connection. The terminal device receives first configuration information sent by the first access network device. The first configuration information includes signaling radio bearer (SRB) configuration information of the second access network device and a trigger condition for using the SRB configuration information. When the trigger condition is met, the terminal device uses the SRB configuration information of the second access network device to establish an RRC connection to the second access network device.

Abstract: An apparatus and a method for transmitting data are included in a wireless network. The apparatus for transmitting data in a wireless network receives a status data packet sent by an upper layer, where the status data packet includes status information of the transmit end in a current status; discards, when there is a cached previous-status data packet, the previous-status data packet and caches the status data packet, where the previous-status data packet includes status information of the transmit end in a previous status; and sends the status data packet to a receive end when obtaining a sending resource, where the previous-status data packet and the status data packet have a same feature. In this way, a data packet delay is reduced; and in an application scenario of the Internet of Vehicles, timely data exchange between vehicles is ensured, and vehicle driving safety is improved.
