Embodiment 1

[0046] In the RRM conformance test example of the TD-LTE communication system, the execution process generally follows the following steps: (1) establish two TD-LTE cells, and set the cell environment to meet specific conditions; Broadcast system messages; (2) The terminal under test is turned on and stays in the state 2A or 3A specified in the TS36.508 specification; (4) After a certain period of time, the power of the cell changes, and the reflection of the terminal under test is observed; (5) According to the (6) Repeat the above steps several times until the confidence requirements are met.

[0047] The reselection test case between same-frequency TD-LTE cells in the idle state is used to verify whether the tested terminal meets the reselection delay specified by 3GPP when reselecting in two adjacent same-frequency cells in the idle state. The delay is defined as the time between when the power parameters of each physical channel of the cell are changed and when the termin...

Embodiment 2

[0061] Such as Figure 6 Shown, utilize the test system of the present invention to carry out the method for TD-LTE terminal protocol consistency test, comprise the following steps:

[0062] S100: Initialize the test system, and automatically create a main test component.

[0063] S200: The main test component judges the type of test currently executed, and determines the number of slave test components to be created. Since the terminal protocol conformance test is performed, the main test component creates a slave test component.

[0064] S300: Execute the executable test case set by using the system simulator from the test component to test the terminal under test, specifically including the following sub-steps:

[0065] S321: The terminal under test completes the cell camping by interpreting the system information.

[0066] S322: The terminal under test establishes a connection with the TD-LTE system simulator, including establishment of an access layer connection and a n...

Embodiment 3

[0071] Such as Figure 7 As shown, the method for performing the terminal radio resource management conformance test by using the above test system includes:

[0072] S100: Initialize the test system, and automatically create a main test component.

[0073] S200: The main test component judges the type of test currently executed, and determines the number of slave test components to be created. Since the terminal wireless resource management consistency test is performed, the main test component creates three slave test components: slave test component 1 and slave test component 2 and from the test component three. The test component one is responsible for constructing the TD-LTE executable test set, the test component two is responsible for constructing the TD-SCDMA executable test set, and the test component three is responsible for constructing the GSM executable test set.

[0074] S300: Jointly execute the RRM consistency executable test case set from the test component ...

Abstract

The invention discloses a terminal test system and a test method. The system comprises a test component and one or more system simulators, wherein the test component is used for controlling, managing and executing a test process; the system simulator is connected with a tested terminal through an air interface and used for realizing a bottom-layer protocol stack; and the test component and the system simulator form a simulated communication system used for testing the tested terminal. According to the method, the test system can be used for testing the terminal. By means of the terminal test system and the test method, the quantity of test components can be flexibly configured according to specific testing contents, and multiple types of test functions are provided; and a time delay observation module is arranged, the high-level signaling processing time delay and the transmission time delay are separated, so that shaking of a timer caused by the high-level signaling processing time delay is avoided, and requirements of a terminal wireless resource management consistency test for time synchronization are met.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a terminal testing system and method. Background technique [0002] With the advancement of the 3rd Generation Partnership Project (3GPP, Time Division-Long Term Evolution) international standard (TD-LTE, Time Division-Long Term Evolution) and related technical tests, the TD-LTE industry chain has gradually formed . According to the latest data from the Global Mobile Suppliers Association (GSA, Global Mobile Suppliers Association) in October 2011, 197 TD-LTE client devices from 48 device manufacturers are ready to go on the market. Compared with the gradual maturity of TD-LTE terminal products, the research and development and maturity of dedicated system simulators used in TD-LTE conformance testing are relatively lagging behind. [0003] The conformance test is to verify the compliance degree of the terminal under test to the relevant protocol. In essen...
