### Claim 5 (depends on 1)

The method as claimed in claim 1, wherein after sending, by the base station, the MSI according to the notification message, the method further comprises:
receiving, by at least one of an On Board Unit (OBU) and a User Equipment (UE), the MSI from the base station; and
acquiring, by at least one of the OBU and the UE, the traffic information on the MTCH according to the MSI.

### Claim 6 (depends on 5)

The method as claimed in claim 5, wherein acquiring, by at least one of the OBU and the UE, the traffic information on the MTCH according to the MSI comprises:
reading, by at least one of the OBU and the UE, MTCH data according to the MSI, and determining, by at least one of the OBU and the UE, that the traffic information on the MTCH is required traffic information according to location information of the traffic information contained in the MTCH data and information about a location where at least one of the OBU and the UE is.

### Claim 7 (depends on 1)

The method as claimed in claim 1, wherein after sending, by the base station, the MSI according to the notification message, the method further comprises:
receiving, by at least one of an On Board Unit (OBU) and a User Equipment (UE), an expanded Multicast Control Channel (MCCH) message from the base station; and
acquiring, by at least one of the OBU and the UE according to the MCCH message, the MSI and the traffic information on a required MTCH.

### Claim 8 (depends on 7)

The method as claimed in claim 7, wherein acquiring, by at least one of the OBU and the UE according to the MCCH message, the MSI and the traffic information on the MTCH comprises:
determining, by at least one of the OBU and the UE, that the traffic information on the MTCH is the required traffic information according to a Temporary Mobile Group Identity (TMGI) carried in the MCCH message; and
