Abstract

The invention concerns a method for distribution of data packets (MBMS Data) from an access network node (aGW) via at least one base station (eNB) to at least one user terminal (UE) in a single frequency mobile communication network whereby information (T1(tx), T2(tx)) is added in the access network node (aGW) to the data packets (MBMS Data) indicating in which time intervals the data packets (MBMS Data) have to be sent from the at least one base station (eNB) to the at least one user terminal (UE), and information (SN) is added in the access network node (aGW) to the data packets (MBMS Data) indicating the order of the distribution of the data packets (MBMS Data), an access network node (aGW), a base station (eNB) and a single frequency mobile communication network therefor.

Claims

1. A method for distribution of data packets from an access network node via at least one base station to at least one user terminal in a single frequency mobile communication network wherein,

that information is added in the access network node to the data packets indicating in which time intervals the data packets have to be sent from the at least one base station to the at least one user terminal,

and that information is added in the access network node to the data packets indicating the order of the distribution of the data packets.

2. A method according to claim 1, wherein information indicating a new time interval is added if the transmission of a new burst is started, a maximum time interval length has been exceeded, or the data rate of data packets that have to be transmitted within one time interval is for a certain time period below a maximum service data rate.

3. A method according to claim 1, wherein based on said information indicating the order of the distribution of the data packets, said at least one base station performs a re-ordering of data packets received out of sequence.

4. A method according to claim 1, wherein a data packet that does not completely fit in a transport block sent from the at least one base station to the at least one user terminal is segmented, or a data packet that does not occupy the whole length of the transport block is concatenated with at least one subsequent data packet.

5. A method according to claim 1, wherein the beginning of said time intervals is based on information about the transmission delay from the access network node to the at least one user terminal.

6. An access network node for distribution of data packets from said access network node via at least one base station to at least one user terminal in a single frequency mobile communication network wherein said access network node comprises at least one processing means

adapted to perform adding of information to the data packets indicating in which time intervals the data packets have to be sent from the at least one base station to the at least one user terminal,

and adapted to perform adding of information to the data packets indicating the order of the distribution of the data packets.

7. A base station for distribution of data packets from an access network node via said base station to at least one user terminal in a single frequency mobile communication network, wherein said base station comprises at least one processing means

adapted to perform sending of said data packets to said at least one user terminal in a respective time interval that is indicated in information added to the data packets,

and adapted to perform sending of said data packets to said at least one user terminal in an order that is indicated in information added to the data packets.

8. A single frequency mobile communication network for distribution of data packets from an access network node via at least one base station to at least one user terminal wherein said single frequency mobile communication network comprises

at least one access network node comprising at least one processing means adapted to perform adding of information to the data packets indicating in which time intervals the data packets have to be sent from the at least one base station to the at least one user terminal, and adapted to perform adding of information to the data packets indicating the order of the distribution of the data packets,

and at least one base station comprising at least one processing means adapted to perform sending of said data packets to said at least one user terminal in a respective time interval that is indicated in information added to the data packets, and adapted to perform sending of said data packets to said at least one user terminal in an order that is indicated in information added to the data packets.
