Method for managing random access process in long term evolution network and user equipment

Abstract

Disclosed are a random access procedure management method and user equipment in a long term evolution network. The method includes: user equipment triggering a random access procedure, and entering a random access preparation state; the user equipment judging whether the random access procedure should be ended, and if the judgement is yes, then ending the random access procedure; and if the judgement is no, then continuing to judge whether the random access procedure should be ended until the time when the user equipment is in the random access preparation state reaches a pre-determined time duration; and if the time when the user equipment is in the random access preparation state reaches a pre-determined time duration, the user equipment executing the random access procedure. Implementing the embodiments of the present invention can reduce the number of times the random access procedure is executed, and improve the access performance of the entire long term evolution network.

Description

technical field [0001] The present invention relates to the communication field, in particular to a random access process management method in a long-term evolution network and user equipment. Background technique [0002] In the existing Long Term Evolution (LTE) system, all user equipment (User Equipment, UE) that have established connections with an evolved base station (evolved NodeB, eNB) share air interface resources, that is, the eNB transmits Time Interval, TTI) dynamically allocates transmission resources for subordinate UEs according to information such as UE data volume. In uplink data scheduling, the UE reports its buffered data volume to the eNB by sending a buffer status report (Buffer Status Report, BSR), thereby providing reference information for uplink scheduling of the eNB. The following describes the BSR reporting mechanism currently used in the LTE system in detail: [0003] When at least one BSR is triggered (and not canceled), the media access contro...

like figure 2 As shown, when the random access is triggered, its random access process is triggered immediately, and at this time, the UE enters the random access process processing state. If the eNB sends an SR resource to the UE before the random access sequence is sent, the UE takes effect. SR resources, but since the UE has entered the random access process processing state, the current implementation will not cancel the random access process; this means that the current processing has SR resources valid and triggers the random access process used to apply for uplink authorization resources entry process
