Data Transmission Method, Terminal, and Base Station

Abstract

Embodiments of the present disclosure provide a data transmission method, terminal, and base station, relate to the communications field, and can improve data packet transmission efficiency. The data transmission method includes: receiving, by a terminal in an idle state, a first resource sent from a base station, where the first resource is used by the terminal to send an uplink application layer data packet to the base station; and sending, by the terminal, on the first resource, the uplink application layer data packet to the base station. The data transmission method is applied to the data transmission system.

What is claimed is: 
     
         1 . A communication method, comprising:
 receiving, by a terminal in an inactive state, a system broadcast message from a network node, wherein the system broadcast message comprises first resource information; and   sending, in response to an amount of to-be-sent data of the terminal being less than or equal to a first threshold, by the terminal in the inactive state, on a resource indicated by the first resource information, an uplink application layer data packet to the network node.   
     
     
         2 . The method according to  claim 1 , wherein the inactive state is a state in which the terminal has a radio network temporary identifier (RNTI) shared in an area of multiple cells. 
     
     
         3 . The method according to  claim 1 , wherein the method further comprises:
 after sending the uplink application layer data packet on the resource indicated by the first resource information to the network node, receiving, by the terminal, a downlink application layer data packet, a downlink signaling data packet, or a downlink media access control (MAC) layer control packet from the network node, wherein the downlink application layer data packet, the downlink signaling data packet, or the downlink MAC layer control packet comprises an identifier of the terminal;   determining, by the terminal, according to the identifier of the terminal, that the uplink application layer data packet is received by the network node.   
     
     
         4 . An apparatus, which is a terminal or included in the terminal, comprising:
 at least one processor coupled to a memory having a computer program stored; and   wherein the computer program, when executed by the at least one processor, cause the apparatus to perform operations comprising:   receiving, while the terminal is in an active state, a system broadcast message from a network node, wherein the system broadcast message comprises first resource information; and   sending, in response to an amount of to-be-sent data of the terminal being less than or equal to a first threshold, on a resource indicated by the first resource information, an uplink application layer data packet to the network node.   
     
     
         5 . The apparatus according to  claim 4 , wherein the inactive state is a state in which the terminal has a radio network temporary identifier (RNTI) shared in an area of multiple cells. 
     
     
         6 . The apparatus according to  claim 4 , wherein the operations further comprises:
 after sending the uplink application layer data packet on the resource indicated by the first resource information to the network node, receiving a downlink application layer data packet, a downlink signaling data packet, or a downlink media access control (MAC) layer control packet from the network node, wherein the downlink application layer data packet, the downlink signaling data packet, or the downlink MAC layer control packet comprises an identifier of the terminal;   determining, according to the identifier of the terminal, that the uplink application layer data packet is received by the network node.   
     
     
         7 . A communication method, comprising:
 sending, by a network node, a system broadcast message that comprises first resource information; and   receiving, by the network node on a resource indicated by the first resource information, an uplink application layer data packet sent by a terminal in an inactive state in response to an amount of to-be-sent data of the terminal being less than or equal to a first threshold.   
     
     
         8 . The method according to  claim 7 , wherein the inactive state is a state in which the terminal has a radio network temporary identifier (RNTI) shared in an area of multiple cells. 
     
     
         9 . The method according to  claim 7 , wherein the method further comprises:
 after receiving the uplink application layer data packet on the resource indicated by the first resource information from the terminal, sending, by the network node, a downlink application layer data packet, a downlink signaling data packet, or a downlink media access control (MAC) layer control packet to the terminal, wherein the downlink application layer data packet, the downlink signaling data packet, or the downlink MAC layer control packet comprises an identifier of the terminal.   
     
     
         10 . An apparatus, which is a network node or included in the network node, comprising:
 at least one processor coupled to a memory having a computer program stored; and   wherein the computer program, when executed by the at least one processor, cause the apparatus to perform operations comprising:   sending a system broadcast message that comprises first resource information; and   receiving, on a resource indicated by the first resource information, an uplink application layer data packet sent by a terminal in an inactive state in response to an amount of to-be-sent data of the terminal being less than or equal to a first threshold.   
     
     
         11 . The apparatus according to  claim 10 , wherein the inactive state is a state in which the terminal has a radio network temporary identifier (RNTI) shared in an area of multiple cells. 
     
     
         12 . The apparatus according to  claim 10 , wherein the operations further comprises:
 after receiving the uplink application layer data packet on the resource indicated by the first resource information from the terminal, sending a downlink application layer data packet, a downlink signaling data packet, or a downlink media access control (MAC) layer control packet to the terminal, wherein the downlink application layer data packet, the downlink signaling data packet, or the downlink MAC layer control packet comprises an identifier of the terminal.
