Abstract

The present invention provides a multi-antenna processing method and device under free flow and an RSU. According to the application, after a current RSU establishes a transaction with an OBU, an RSU adjacent to the current RSU is most likely to cause interference for the OBU, and then effectiveness of a random number can be affected. As a result, according to the application, before an encrypted write operation is performed for the OBU through the obtained random number, a transaction process of the RSU adjacent to the current RSU is at least suspended, then the current RSU or other RSU utilizes the random number to perform encrypted write operation for the OBU, after the encrypted write operation is successful, the effectiveness of the random number cannot be affected by the transaction process of the other RSU, thus the suspended transaction process of the RSU can be continued at the moment. According to the application, there is no RSU affecting the effectiveness of the random number used in an encryption process, thus the OBU cannot be locked when the random number is utilized for performing an encryption operation for the OBU, thereby improving a transaction success rate and facilitating use of a user.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a free-flow multi-antenna processing method, device and RSU. Background technique [0002] In the ETC free flow system, in order to improve the success rate and efficiency of marking, one or even two RSUs are installed on a lane to trade with OBUs. In order to process OBUs concurrently, different RSUs may process the same OBU at the same time. During a transaction between an RSU and an OBU, the RSU needs to obtain a random number for the OBU and perform an encrypted write operation. When a certain RSU (hereinafter referred to as RSU*) obtains a random number for the OBU and is ready to perform an encrypted write operation on the OBU, Another RSU trades with the OBU, and the OBU responds to the transaction of the other RSU, and thinks that the random number taken by the RSU* is invalid. At this time, the RSU* does not know that the random number taken is invalid, an...
