Random access processing method and user equipment

Abstract

The invention provides a random access processing method and user equipment. The method comprises that: after receiving current random access response information from an evolved node B, comparing current uplink authorization information in the current random access response information with pre-stored uplink authorization information, wherein the pre-stored uplink authorization information is uplink authorization information in the last random access response information received in the last random access process; when the current uplink authorization information is inconsistent with the pre-stored uplink authorization information, scheduling and packing data according to the current uplink authorization information to generate a first data packet carrying a user equipment identifier; transmitting the first data packet to the evolved node B, and receiving a second data packet from the evolved node B; resolving the second data packet; and judging whether competition for random access is successful or not according to a resolution result. In the technical scheme of the embodiment of the invention, the success rate of the random access of the user equipment can be effectively increased.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a random access processing method and user equipment. Background technique [0002] With the third generation (The 3rd Generation; hereinafter referred to as 3G) mobile communication technology as the mainstream technology of wireless communication, the Universal Mobile Telecommunications System (Universal Mobile Telecommunications System) developed by the 3rd Generation Partnership Project (hereinafter referred to as 3GPP) ; hereinafter referred to as UMTS) has influence in the industry. In order to further consolidate the status of 3GPP in wireless technology standards. The 3GPP technology introduces the Long Term Evolution (hereinafter referred to as LTE) system, takes Orthogonal frequency-division multiplexing (hereinafter referred to as OFDM) as the core, and adopts the Multiple-Input Multiple-Output (Multiple-Input Multiple- Output;...

Problems solved by technology

[0004] In the process of implementing the present invention, the inventors found that there are at least the following problems in the prior art: when the UE performs random access for the second time or more, if the cell where the UE is located at this time is in a radio resource control connected (Radio Resource Control CONNECTED; Hereinafter referred to as RRC_CONNECTED) state, that is, in the case of close to full load, in order to access more UEs, the eNB reduces the uplink authorization resources allocated to the RAR corresponding to the UE during this access request, causing the uplink authorization to be different from the previous one. The uplink authorization during access is inconsistent. When the UE sends Msg3 to the eNB to request to establish a wireless connection with the eNB, the UE access fails
