Embodiment approach 1

[0023] In the scenario of random access, except for non-contention random access in the case of handover, other scenarios use contention random access, including random access after non-contention random access fails during handover or non-contention access code times out . Some of the information carried in the message 3 of the contention random access process needs to be processed by the MAC layer, and some needs to be processed by the RRC layer, and the length of these messages can be changed. The eNB needs to distinguish the UE according to the C-RNTI, so that the encrypted and integrity-protected RRC message carried in message 3 can be processed at the upper layer using the key of the correct UE. refer to figure 1 , is a method for sending information in a random access process according to the first embodiment of the present invention. In this embodiment, the specific method includes:

Abstract

The invention discloses a method for sending information in random access process which includes: bearing C-RNTI by MAC control unit, or bearing C-RNTI in MAC head structure; sending the C-RNTI. The invention also discloses a terminal which includes a configuration unit for configurating C-RNTI bore by MAC control unit or C-RNTI bore by MAC head structure; a sending unit for sending C-RNTI configurated by the configurating unit. The invention also discloses a method for treating information in a random access process, a network side device and a communication system. C-RNTI is bore by the MAC control unit or MAC head structure that can definitude C-RNTI concrete representation and utilize existing mechanism MAC control unit for bearing C-RNTI, solve problem of distinguishing UE in MAC layer simply and conveniently, and has little change to existing system.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, device and communication system for sending and processing information in a random access process. Background technique [0002] In a wireless access system, a terminal (User Equipment, EU) needs a random access process to access the network, and accesses the network through a random access channel (Radom Access Channel, RACH). In the existing long term evolution (Long Term Evolution, LTE) system, the random access process is required in the following situations: initial access from idle state; initial access after radio link failure; Initial access; random access process when downlink data arrives in the radio resource control connection state, such as when the uplink synchronization state is out of sync; random access when there is uplink data transmission in the radio resource control connection state, such as When the uplink synchronization s...
