[0031] Functional Overview

[0032] Considering that in the process of random access, when network optimization is performed by inputting parameters, it is impossible to accurately obtain relevant parameter information reflecting conflicts, delays, and failures in the process of random access, an embodiment of the present invention provides a random Access information acquisition scheme, in the embodiment of the present invention, the UE performs statistical measurement on the parameter information in the random access process, and the parameter information statistically by the UE includes parameters indicating conflict information occurring in the random access process and parameters indicating random access information. Parameters of the delay information that occurs during the access process. After obtaining the parameter information in the random access process, the UE reports part or all of the obtained parameter information to the base station after the random access is ...

Abstract

The invention discloses a method for acquiring random access information and a user facility. The method comprises the following steps: in the process of random access, the user facility measures parameter information and acquires the parameter information; and after the random access is successful, the user facility reports part or all of the acquired parameter information to a base station. By using the invention, the base station can optimize the random access according to the parameter information reported by a terminal, and the accuracy of random access optimization is enhanced.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a random access information acquisition method and user equipment (User Equipment, referred to as UE for short). Background technique [0002] A Long Term Evolution (LTE for short) network consists of an Evolved Universal Terrestrial Radio Access Network (E-UTRAN for short) and an Evolved Packet Core (EPC for short). The LTE network is flat, and the E-UTRAN may be composed of multiple evolved base stations (Evolved NodeB, eNB for short) connected to the EPC. [0003] In the LTE system, if the UE needs to interact with the network side, it first needs to obtain uplink synchronization and initiate a random access process, wherein the random access process can be divided into contention-based random access process and Competitive random access procedure. [0004] figure 1 is a flowchart of the contention-based random access process, such as figure 1 As shown, the contention ra...
