Transmission of Data Within a Communications Network
The invention relates to methods for providing a network element 5 of a communications network with data, in particular HSDPA related data. In order to enable the transmission of user data, it is proposed that a controller 4 of the network uses a dedicated frame structure for assembling frames with said user data. The frames can then be transmitted from the controller 4 via an interface to the network element 5 . In order to enable the transmission of control parameters, it is further proposed that an interface application protocol is employed which allows the controller 4 to add control parameters to control messages transmitted from the controller 4 to a network element 5 via the interface.
1 . An apparatus for communication between a first network element and a second network element in a communication network, the method comprising:
a memory for storing data;
a processor coupled to the memory, the processor configured to:
determine, whether multiplexing of user data destined to a plurality of user equipment is supported;
when multiplexing of user data is supported, multiplex a set of user data from different logical channels into a transport channel message;
identify, in a header portion of the message, whether multiplexing of the user data is included in a payload portion of the message; and
transmit, from the first network element, the message to the second network element.
2 . The apparatus according to claim 1 wherein the user data is multiplexed at a MAC Layer entity.
3 . The apparatus according to claim 1 wherein the user data is multiplexed at a Frame Protocol Layer entity.
4 . The apparatus according to claim 1 wherein multiplexing of user data identified as a number of buffers in the header portion of the message.
5 . The apparatus according to claim 1 wherein the multiplexing of user data is identified as a number of user identification in the header portion of the message.
6 . A method for communication between a first network element and a second network element in a communication network, the method comprising:
determining, at the first network element, whether multiplexing of user data destined to a plurality of user equipment is supported;
when multiplexing of user data is supported, multiplexing a set of user data from different logical channels into a transport channel message;
identifying, in a header portion of the message, whether multiplexing of the user data is included in a payload portion of the message; and
transmitting, from the first network element, the message to the second network element.
