Abstract
A central unit (CU) of a distributed base station transmits, to a core network (CN), a distribution setup request message: receives, from the CN, a distribution setup response message including a first MBS QoS flow configuration; and transmits, to a distributed unit (DU) of the distributed base station, a multicast context setup request message including a second MBS QOS flow configuration based on the first MBS QoS flow configuration, to establish a multicast context for an MBS session.
Claims20
A method for multicast session establishment, the method implemented in a central unit (CU) of a distributed base station and comprising:
- transmitting, to a core network (CN), a distribution setup request message;
- receiving, from the CN, a distribution setup response message including a first MBS QoS flow configuration;
- and
- transmitting, to a distributed unit (DU) of the distributed base station, a multicast context setup request message including a second MBS QoS flow configuration based on the first MBS QoS flow configuration, to establish a multicast context for an MBS session.
An apparatus, operating as a central unit (CU) of a distributed base station and configured for multicast session establishment, the apparatus comprising:
- processing hardware configured to:
- transmit, to a core network (CN), a distribution setup request message;
- receive, from the CN, a distribution setup response message including a first MBS QoS flow configuration;
- and
- transmit, to a distributed unit (DU) of the distributed base station, a multicast context setup request message including a second MBS QoS flow configuration based on the first MBS QoS flow configuration, to establish a multicast context for an MBS session.
