Abstract: Embodiments of this application provide a configuration method and apparatus. When indicating, by using an RRC connection release message, a terminal to enter an inactive state from a connected state, a network device may include, in the RRC connection release message, a configuration parameter allocated to the terminal in the inactive state. That is, the terminal receives the radio resource control RRC connection release message sent by the network device, where the RRC connection release message includes first information used to indicate a target configuration parameter. In this way, the terminal may enter the inactive state based on the RRC connection release message, and determine a context parameter of the inactive state based on the first information, so that the configuration parameter is properly allocated to the terminal in the inactive state.

Abstract: This application provides a communication processing method for data transmission. A terminal-side device may adjust transmission of an uplink data burst in time based on time of arriving at an access stratum of the terminal-side device, a maximum peak rate, and a maximum data burst volume that are indicated by a network. This helps adapt to a network resource and improve a network load balancing capability.

Abstract: Embodiments of this application provide a random access processing method. A random access preamble and uplink data are sent in an initiation phase of a random access procedure, and the random access procedure is ended in time after feedback information for the uplink data is received. According to technical solutions provided in the embodiments of this application, a terminal side device may send the uplink data when sending the random access preamble in the random access procedure. In addition, the random access procedure can be ended in advance after the feedback information for the uplink data is received.
