Description

Data transmitting method, data receiving method and device

Technical Field

The present invention relates to the field of communications, and in particular, to a method and an apparatus for transmitting and receiving data.

Background

In the related art, a terminal in an idle state needs to send data, and must first enter a connected state, and then perform data sending according to the connected state, and after the data sending is completed, return to the idle state again or continue to stay in the connected state. Fig. 1 is a schematic diagram of a process of sending Network Attached Storage (NAS) information in an idle state of a terminal in the related art, as shown in fig. 1. A terminal needs to establish Radio Resource Control (RRC) connection with a base station, then a bearer is established between the base station and a core network, the terminal can send data to the core network through the base station, after the data is sent, the bearer between the base station and the core network is released, and then the RRC connection between the terminal and the base station is released.

In the LTE system, before a UE in a connected state sends data to a base station, uplink synchronization and downlink synchronization with the base station need to be obtained. Fig. 2 is a schematic diagram of a random access procedure in an LTE system in the related art, as shown in fig. 2, a collision (collision based) random access procedure is shown in fig. 2, and includes four steps, wherein steps 3 and 4 are used to resolve a collision, and the non-collision based procedure has only the first two steps.

To meet the anticipated future demands for higher, faster, and more up-to-date communications, the industry has begun to develop research into future 5G technologies. The 5G will conduct further technical research in terms of higher throughput, more user connections, lower latency, higher reliability, and lower power consumption (including network side equipment and user terminals). In order to meet the requirement that the terminal can quickly send data in a 5G scene, the terminal needs to be in an inactive state and can quickly execute when the terminal has a data sending requirement, but no technical solution is disclosed at present how the terminal sends data in the inactive state.
