The present application relates to broadcast bearer management methods and devices. One example method includes receiving, by a first bearer management server (BMS), a first message sent by a service server, where the first message includes a group identifier of a service group, determining, by the first BMS, a first broadcast bearer for the service group based on the first message, and sending, by the first BMS, a second message to the service server, where the second message carries user plane information of the first broadcast bearer.
