Embodiment 1
[0054] Such as figure 2 As shown, the process of performing a cell reselection capability test on a terminal in the medium-speed mobile mode may specifically include the following steps:
[0055] Step 201: terminal A camps on cell 1;
[0056] Step 202: Terminal A enters the medium-speed mobility mode, and finally resides in cell 1;
[0057] Here, the system simulator changes the transmission power of cell 1 and cell 2 multiple times, so that terminal A enters the medium-speed mobile mode after switching between cell 1 and cell 2 several times, and finally resides in cell 1;
[0058] Here, cell 1 and cell 2 are adjacent cells. Specifically, change the transmit power of cell 1 and cell 2 so that the transmit power of cell 1 is much greater than the transmit power of cell 2, or the transmit function of cell 2 is much greater than the transmit power of cell 1, so that terminal A can Handover with cell 2. Finally, the transmit power of cell 1 is made much greater than the tran...
Embodiment 2
[0067] Such as image 3 As shown, in this embodiment, the process of performing a cell reselection capability test on a terminal in a high-speed mobile mode may specifically include the following steps:
[0068] Step 301: terminal A camps on cell 1;
[0069] Step 302: Terminal A enters the high-speed mobility mode, and finally resides in cell 1;
[0070] Here, the system simulator changes the transmission power of cell 1 and cell 2 multiple times, so that terminal A enters the high-speed mobility mode after switching between cell 1 and cell 2 several times, and finally resides in cell 1.
[0071]Specifically, the system simulator will include a maximum number of cell reselections (Ncr-h) for entering the high-speed mobility state and a maximum number of cell movements (Ncr-m) for entering the medium-speed mobility state in the system information sent to the terminal , and cell reselection times evaluation time value (Tcr), wherein, Ncr-h>Ncr-m If in any period equal to TCR, ...

Abstract
The invention discloses a method for testing a terminal cell reselection ability. The method comprises the following steps: adjusting the terminal to stay in a current cell and entering into a high-speed or medium-speed mode; adjusting emission powers of the current cell and an adjacent cell so that the current cell and the adjacent cell satisfy a reselection condition from the current cell to the adjacent cell under the high-speed or medium-speed mobile mode; maintaining the adjusted emission powers till a preset time threshold is reached; and then detecting whether the terminal carries out cell reselection successfully through detecting whether the terminal stays in the adjacent cell. The invention also discloses an apparatus of testing the terminal cell reselection ability. In the invention, a test of whether the terminal possesses the cell reselection ability under the high-speed or medium-speed mobile mode can be realized. Therefore, in actual generation, authentication and the test of whether the terminal possesses the cell reselection ability can be achieved.
Description
technical field [0001] The present invention relates to the testing technology of terminal capability in Long Time Evolution (LTE, Long Time Evolution) technology, in particular to a method and device for testing terminal cell reselection capability. Background technique [0002] The third-generation communication technology (3G, 3rd-generation) adopts the access method of code division multiple access to support multimedia services, and has better communication security and communication than the second-generation communication technology (2G, 2nd-generation). Quality makes 3G highly competitive in the next few years. In order to meet people's higher communication needs, provide better communication services, and ensure that 3G technology is more competitive, the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) has launched a 3G LTE research project. [0003] At present, LTE has formed a complete wireless communication standard, and it is gradu...
