The method may be applied to a network side device. After receiving a connection establishment request transmitted by user equipment, identification information of a plurality of network slices being carried in the connection establishment request, the network side device determines whether the plurality of network slices correspond to a same vehicle communication service according to the identification information of the plurality of network slices. When the plurality of network slices are determined to correspond to the same vehicle communication service, the network side device establishes a protocol data unit (PDU) session with the user equipment. The technical solutions of the embodiments of this application increase the number of vehicle communication use cases that the user equipment can support, and facilitate a promotion and a deployment of an Internet of Vehicles solution. ## Claims ### Claim 1 A vehicle communication method, comprising: receiving, by a network side device, a connection establishment request transmitted by user equipment, wherein identification information of a plurality of network slices is carried in the connection establishment request;
