Abstract
A method and apparatus can be configured to receive an indication for support for a broadcast service enhancement layer from a first network node. The method may also comprise transmitting the indication for support for the broadcast service enhancement layer to a second network node. The method may also comprise receiving a broadcast service session request message from the second network node. The broadcast service session request message may indicate that a broadcast service session is for a base layer or for the enhancement layer.
Claims20
A first base station comprising:
- at least one processor and at least one memory including a computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the first base station to:
- receive an indication for support for a broadcast service enhancement layer from a second base station;
- transmit the indication for support for the broadcast service enhancement layer to a broadcast service coordination entity;
- receive a broadcast service session request message from the broadcast service coordination entity;
- determine that the broadcast service session request message indicates that a broadcast service session is for an enhancement layer;
- provide a base layer of the broadcast service session to a user equipment having a low data rate connection and to a user equipment having a high data rate connection;
- transmit the broadcast service session request message to the second base station;
- and
- cause the second base station to transmit the enhancement layer of the broadcast service session to the user equipment having the high data rate connection.
A second base station comprising:
- at least one processor and at least one memory including a computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the second base station to:
- determine that the second base station supports for a broadcast service enhancement layer;
- transmit an indication for support for the broadcast service enhancement layer to a first base station;
- receive a broadcast service session request message from the first base station;
- determine that the received broadcast service session request message indicates that a broadcast service session is for an enhancement layer;
- and
- transmit the enhancement layer of the broadcast service session to a user equipment having a high data rate connection, wherein a base layer of the broadcast service session is provided to the user equipment having the high data rate connection and to a user equipment having a low data rate connection by the first base station.
A method, comprising:
- receiving, by a first base station, an indication for support for a broadcast service enhancement layer from a second base station;
- transmitting the indication for support for the broadcast service enhancement layer to a broadcast service coordination entity;
- receiving a broadcast service session request message from the broadcast service coordination entity;
- determining that the broadcast service session request message indicates that a broadcast service session is for an enhancement layer;
- providing a base layer of the broadcast service session to a user equipment having a low data rate connection and to a user equipment having a high data rate connection;
- transmitting the broadcast service session request message to the second base station;
- and
- causing the second base station to transmit the enhancement layer of the broadcast service session to the user equipment having the high data rate connection.
