Embodiment 1

[0052] image 3 is a schematic diagram of sending MDT measurement configuration information according to the preferred embodiment 1 of the present invention, as shown in image 3 As shown, the random access performance of a certain cell needs to be optimized, and the UE random access information is collected through the MDT mechanism. image 3 Taking the measurement information of the UE in the idle state (Logged) as an example, when the UE is in the connected state, the measurement result is reported to the base station, and the processing process is as follows:

[0053] When it is necessary to optimize the random access configuration parameters of a certain cell (cell1), OAM searches for all adjacent cells (cell2...celln) of the cell; in order to fully obtain the random access information of the cell (cell1), OAM sets the The number of dedicated random access preambles is 0, so that when UEs in other cells switch to cell1, a contention-based random access process is perform...

Embodiment 2

[0058] Figure 4 is a schematic diagram of reporting MDT measurement configuration information according to the second preferred embodiment of the present invention, as shown in Figure 4 As shown, the main description is that the UE side performs the MDT measurement and the reporting of the measurement results. The specific process is as follows (only steps S402 to S404 are shown in the figure):

[0059] In a commercial environment, the UEs in the cell are randomly distributed. When some UEs in cell2...celln move to the direction of cell1 and handover occurs, OAM controls the UEs to perform contention-based random access; according to the MDT measurement configuration Information, the UE records its detailed information when it performs random access in cell1, the information at least includes the sending time of each preamble sequence of each random access (the time is synchronized with the eNB), the preamble sequence index, and the location information of the UE.

Abstract

The invention discloses a user equipment (UE) access information acquisition method and device. The UE access information acquisition method comprises the following steps: a base station receives MDT (Minimization of Drive Tests) measurement configuration information from OAM (Operation Administration and maintenance), wherein the MDT measurement configuration information carries UE random access preamble measurement configuration information; and the base station acquires the access information of UE according to the MDT measurement configuration information. According to the UE access information acquisition method and device, the base station automatically acquires the access information of the UE by using an MDT technology according to the MDT measurement configuration information issued by the OAM, and further evaluates the random access property of a cell at certain time slot according to the access information without the need of simulating such complex operations by using a test instrument, thus the optimization flow of a random access channel is simplified, the manual intervention degree is reduced, and the user network operation and maintenance cost is saved.

Description

technical field [0001] The present invention relates to the communication field, and in particular, to a method and device for acquiring access information of a user equipment (User Equipment, referred to as UE for short). Background technique [0002] Unreasonable parameter configuration of a Random Access Channel (RACH for short) in a wireless communication system will have a negative impact on user experience. Unreasonable RACH parameter configuration will lead to the following problems: large handover delay, low call establishment success rate, and low handover success rate. In order to improve the coverage and capacity of the LTE system and improve user experience, it is necessary to optimize the access performance of the RACH channel of the cell in the network to optimize the random access processing capability and performance of the system. [0003] The premise of optimizing the RACH channel of the cell is to obtain the current random access performance of the cell, ...
