Abstract
A method for bearer control, bearer deletion, data distribution, and multicast broadcast service MBS modification are described, which enables MBS data to be received successfully and MBS sessions to be managed effectively. According to the invention involved in a communication field, service distribution information for one MBS service is maintained within MBS upstream and downstream nodes, and the MBS service distribution information is composed of a list of downstream nodes corresponding to the respective nodes. A corresponding service bearer and data distribution relation of the MBS are established and maintained based on the service distribution information, and service data of the MBS is distributed based on the service bearer and the data distribution relation. The MBS distribution information is pre-configured and/or dynamically maintained, the establishment of the service bearer is pre-configured and/or dynamically maintained, and the data distribution relation is pre-configured, distributed by default, and/or dynamically maintained.
