Distributing content to a plurality of mobile stations using a downlink point-to-multipoint (PTM) bearers and downlink point-to-point (PTP) bearers

摘要

A method and apparatus is provided for distributing content to a plurality of mobile stations using a downlink point-to-multipoint (PTM) bearers and downlink point-to-point (PTP) bearers. A controller can process events, to determine whether a current modulation-and-coding scheme (MCS) level applied to downlink transmissions over the downlink PTM bearer is to be changed or maintained, and to communicate a change message whenever the current MCS level is to be changed. An actuator can adjust, in response to receiving a change message, a MCS level that is applied to downlink transmissions over the downlink PTM bearer.

1. A method for distributing content to a plurality of mobile stations, the method comprising:
processing an event at a controller residing above a core network, wherein the core network resides above a radio access network comprising one or more base stations; determining, at the controller based on the event, whether a current modulation-and-coding scheme (MCS) level, applied to a downlink point-to-multipoint (PTM) bearer, is to be changed or maintained; communicating a change message from the controller to an actuator implemented by an infrastructure device of the core network when the controller determines that the current MCS level is to be changed; and adjusting, at the actuator each time a change message is received, a MCS level that is applied to downlink transmissions to the plurality of mobile stations over the downlink PTM bearer.
