Description

Communication method, device, user equipment, network equipment and medium Technical Field The present application relates to the field of communications technologies, and in particular, to a communications method, an apparatus, a user device, a network device, and a medium. Background The random access procedure (RandomAccess Procedure, RAP) refers to a key step of establishing an initial connection and recovering a connection between a User Equipment (UE) and a base station. The RAP mainly comprises the following four steps: s1, the UE sends a first message (namely msg 1) to the base station. I.e. the UE sends a random access preamble sequence (RandomAccess Preamble) to the base station, helping the base station to identify the UE. S2, the base station sends a second message (namely msg 2) to the UE. The base station feeds back a random access response (RandomAccess Response, RAR) to the UE via msg2 for subsequent uplink transmission by the UE. And S3, the UE sends a third message (namely msg 3) to the base station. The UE sends a connection request to the base station through msg 3. And S4, the base station sends a fourth message (namely msg 4) to the UE. The base station feeds back the contention resolution identification to the UE through msg4, and the UE determines whether the contention is successful or not based on the contention resolution identification. In recent years, mobile-Originatinged EARLY DATA Transmission (MO-EDT) has been introduced for improving data Transmission efficiency by reducing delay in connection establishment. MO-EDT allows the UE to directly transmit the UE's user data in msg3 of RAP without waiting for the complete connection establishment procedure, thus enabling to reduce the delay of connection establishment. However, before transmitting user data using msg3, the base station and the UE still need to transmit the random access preamble sequence and the RAR. The method increases the overhead of uplink signaling and downlink signaling, and affects the utilization rate of uplink resources and downlink resources. Disclosure of Invention The embodiment of the application provides a communication method, a device, user equipment, network equipment and a medium, which can directly utilize msg3 information to send user data of UE without sending random access preamble sequences and RARs, so that the cost of uplink signaling and downlink signaling can be reduced, and the utilization rate of uplink resources and downlink resources can be improved. In order to achieve the above purpose, the embodiment of the application adopts the following technical scheme: In a first aspect, an embodiment of the present application provides a communication method, and in particular, UE receives configuration information. The configuration information is used for enabling the equipment in the first cell to directly execute the operation of transmitting data based on the contention-based MO-EDT, wherein the equipment of the first cell comprises user equipment. And the UE sends a target request message according to the configuration information and the trigger information of the UE. The target request message is a message carrying user data of the UE, or the target request message is a message multiplexed with the user data, and the trigger information is used for determining whether the UE can perform a contention-based MO-EDT data transmission operation. For example, in a communication system comprising a network device and a UE, the network device covers a first cell and the user device is located in the first cell. The network device may send configuration information to the device of the first cell based on a broadcast manner through a system information block (SystemInformationBlock, SIB) or a Narrowband system information block (narrow band SystemInformationBlock, SIB-NB) message, in particular a SIB2 message or a SIB2-NB message. After the UE receives the configuration information based on the broadcast manner, the UE may send the msg3 message based on the configuration information and its own trigger information. Or the UE may also send the configuration information to the device of the first cell through proprietary signaling. The process does not need to send msg1 and msg2, so that the overhead of uplink signaling and downlink signaling in the EDT process is reduced, the utilization rate of uplink resources and downlink resources is improved, and further, the effect of uplink capacity is improved. The trigger information comprises one or more of whether a higher Layer initiates a request for establishing Radio Resource Control (RRC) connection or an RRC connection recovery request, whether a contention-based MO-EDT is supported, whether a received broadcast message carries target indication information and whether a pre-compensated timing advance exists, and whether the target indication information indicates that a network device sending the broadcast message allows the execution of the
