Communication modes such as TD-SCDMA, TD-LTE, CDMA2000, LTE-A, and MBMS need to synchronize base station air interfaces before working properly. IEEE1588 v2, the mainstream high precision timing and synchronization protocol, illustrates that synchronization information can be terrestrially transmitted to solve the potential security problems of GPS signals which are difficult to be obtained in application scenarios like in the subway.
Interoperability test is a very important part in the popularization and application of IEEE1588 v2 technology. When different manufacturers want to interoperate the IEEE1588 messages, they can capture and analyze the messages based on the interconnection templates with the stardard technology from China Mobile, to ensure the protocols compatible and show the results directly, which helps ordinary technicians rapidly fix and solve the interconnection problem of the devices between different manufacturers.
We provide solutions to test the consistency of PTP message and the Tx frequency of PTP packets, and solve the interconnection problem of the devices from different manufacturers.
