Problems solved by technology
Therefore, the network environment of the two standards needs to exist at the same time, and the test cycle is long and the task is heavy.
[0009] In addition, the test process also requires testers to track, and it takes a long time and consumes a lot of manpower
[0010] Moreover, due to the limited LTE-R test environment, general testers lack relevant experience in LTE-R communication systems, which increases the difficulty for manufacturers in testing dual-mode radios

Embodiment Construction
[0058] In order to make the objects, technical solutions, and advantages of the present invention more clearly, the technical solutions in the embodiments in the embodiments will be described in contemplation in the embodiment of the present invention, and will be described in connext of the embodiment of the present invention. It is an embodiment of the invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art are in the range of the present invention without making creative labor premise.
[0059] The present invention provides a method for testing dual-mode car radio, the car radio in a dual mode GSM-R / LTE-R as an example, but the GSM-R 5G-R The same applies / . A method for signaling interaction with the car radio by analog dual mode LTE-R network side device, so that no dual-mode car radio to be tested is placed in a real network environment LTE-R LTE-R vehicle dual-mode radi...

The invention provides a method and system for testing a dual-mode vehicle-mounted radio station, and the method comprises the steps: simulating LTE-R or 5G-R network side equipment which is used forachieving the signaling interaction with the dual-mode vehicle-mounted radio station; setting a preset signaling on the network side equipment; and controlling the network side equipment and the dual-mode vehicle-mounted radio station to carry out automatic interactive communication according to the preset signaling so as to realize automatic test of the dual-mode vehicle-mounted radio station. According to the invention, the method can achieve the automatic testing of the GSM-R / LTE-R or GSM-R / 5G-R dual-mode vehicle-mounted radio station in an environment without LTE-R or 5G-R.
Description
Technical field [0001] The present invention belongs to the field of communication technology rail transportation, and more particularly to a method and system for testing a dual mode of the car radio. Background technique [0002] At present, the vast majority of passenger dedicated railway system uses the GSM-R network, but the railway communication system format standard in the evolution to LTE-R-coming publication, and plans to follow-up the use of 5G-R, that is used in transportation and communication railroad track 5G network technology. It is expected that most of the car radio for some time the need to support GSM-R / LTE-R or GSM-R / 5G-R dual-mode communication system, the communication network upgrade process to deal with the whole of the road. [0003] In LTE-R, for example, LTE-R Radio generally shorter development cycle, but expensive LTE-R communication network side device, and since LTE-R communication system having a relatively small-scale public network system, ...
