Abstract
A multimedia broadcast/multicast service (MBMS) in a universal mobile telecommunications system (UMTS) includes a UTRAN that provides an MBMS service. The MBMS service-related information is exchanged between the UTRAN and a terminal or between nodes in the UTRAN by using an MBMS identification so that a user group receiving MBMS data or a data of a specific MBMS service can be identified.
Claims22
In a wireless radio communication network that employs a radio network interface protocol, the protocol including a Radio Resource Control (RRC) layer and a Medium Access Control (MAC) layer, a method of providing a point-to-multipoint service, the method comprising:
- configuring, at the RRC layer, an identifier that identifies the point-to-multipoint service and distinguishes the point-to-multipoint service from other point-to-multipoint services;
- at the MAC layer, adding the identifier to a MAC header of a data unit associated with the point-to-multipoint service, wherein the identifier in the MAC header is used to distinguish between point-to-multipoint services;
- and
- transmitting the data unit to a mobile terminal.
In a wireless radio communication network that employs a radio network interface protocol, the protocol including a Radio Resource Control (RRC) layer and a Medium Access Control (MAC) layer, a method of receiving a point-to-multipoint service, the method comprising:
- receiving a data unit including an identifier which identifies the point-to-multipoint service, wherein the identifier is included in a MAC header of the data unit;
- at the MAC layer, identifying the data unit as being associated with the point-to-multipoint service using the identifier;
- and
- transferring the data in the data unit to an upper layer, wherein the identifier in the MAC header is used to distinguish between point-to-multipoint services, and wherein the identifier was configured by an RRC layer of the network.
In a wireless radio communication network that employs a radio network interface protocol, the protocol including a Radio Resource Control (RRC) layer and a Medium Access Control (MAC) layer, an apparatus capable of receiving a point-to-multipoint service, the apparatus comprising:
- a receiver adapted to receive a data unit that includes an identifier which identifies the point-to-multipoint service, wherein the identifier is included in a MAC header of the data unit;
- and
- at the MAC layer, a MAC entity adapted for identifying the data unit as being associated with the point-to-multipoint service using the identifier, and transferring the data in the data unit to an upper layer, wherein the identifier in the MAC header is used to distinguish between point-to-multipoint services, and wherein the identifier was configured by an RRC layer in the network.
