Problems solved by technology

[0004] However, the state machine of the existing comprehensive tester can easily enter an abnormal state when the terminal initiates an air interface message of an abnormal process, resulting in a functional error in the upper layer protocol stack, and the existing state machine can only respond to a specific terminal access message, which has great limitations

Embodiment Construction

[0074] In order to make the purpose, content, and advantages of the present invention clearer, the specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and examples of the description. The following examples are only used to illustrate the present invention, but are not used to limit the present invention range.

[0075] The invention provides a method for realizing the state machine of an LTE terminal comprehensive tester. The three independent stable states of the state machine can be flexibly migrated, and the LTE terminal tests of different manufacturers can achieve correctness and compatibility. Based on this state machine, other test modules can be expanded, such as LTE terminal measurement report, same-frequency and different-frequency handover, FTP service, etc. (the test function is not described in this article), to further improve the terminal test efficiency.

Abstract

The invention provides a realization method of an LTE terminal comprehensive tester state machine, and belongs to the technical field of mobile communication. The state machine comprises three steady states: an initial state, an idle state and a connected state. The three steady states can be transferred into each other via executing procedures of initialization, registration, calling, on-hook and releasing. The idle state can execute the registration procedure to return to the idle state, and also can execute the calling procedure to transfer to the connected state. A signaling interaction process of an LTE terminal comprehensive tester and a terminal is realized by the state machine via executing a state table constructed on the basis of an LTE standard protocol. According to the realization method of the LTE terminal comprehensive tester state machine, correctness and compatibility of a high-level protocol stack function in the LTE terminal comprehensive tester are ensured, accessing of different protocol state terminals is considered, and a terminal message of an abnormal procedure can be responded so that the realization method of the LTE terminal comprehensive tester state machine has great compatibility and robustness, and thus terminal testing efficiency can be greatly enhanced.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for realizing a state machine of an LTE terminal comprehensive tester. Background technique [0002] In the process of rapid development of the LTE industry, communication test instruments are one of the key links. Among them, the terminal comprehensive tester has become an important basic tool for LTE terminal R&D, production, and certification because it can accurately test all radio frequency performance and basic call / audio functions of the terminal. [0003] The high-level protocol stack module is the core module of the LTE terminal comprehensive tester. On the one hand, it provides the basic functions of the non-access / radio resource control (NAS / RRC) layer specified by the 3GPP protocol, and completes the configuration of the low-level protocol stack and physical layer on the instrument side. As well as the air interface signaling interaction with th...
