Abstract

Methods and apparatus, including computer program products, are provided for charging in multi-connectivity systems. In some example embodiments, there may be provided a method that includes marking, by a first base station serving a user equipment, at least one packet to include a first indication indicating that the at least one packet was received directly at the first base station serving the user equipment; and marking, by the first base station, at least one other packet to include a second indication to indicate that the at least one other packet was received via a second base station also serving the user equipment. Related systems, methods, and articles of manufacture are also described.

First claim

The invention claimed is:

1. A method comprising:
marking, by a first base station serving a user equipment, at least one packet to comprise a first indication indicating that the at least one packet was received directly at the first base station serving the user equipment;
marking, by the first base station, at least one other packet to comprise a second indication to indicate that the at least one other packet was received via a second base station also serving the user equipment;
receiving, at the first base station, a first downlink packet comprising a first downlink packet indication marked by a gateway node to indicate that at least the first downlink packet should be transmitted directly to the user equipment;
receiving, at the first base station, a second downlink packet comprising a second downlink packet indication marked by the gateway node to indicate that at least the second downlink packet should be forwarded to the second base station for transmission to the user equipment; and
reporting, by the first base station and to a network node, a deviation from a resource allocation and at least one of the first indication or the second indication.

2. The method of claim 1 , wherein the first downlink packet indication comprises a cell identifier associated with the first base station and/or a base station identifier identifying the first base station, and wherein the second downlink packet indication comprises another cell identifier associated with the second base station and/or another base station identifier identifying the second base station.

3. The method of claim 2 , further comprising:
sending, by the first base station and based on the first downlink packet indication, the first downlink packet to the user equipment by transmitting the packet directly to the user equipment; and
sending, by the first base station and based on the second downlink packet indication, the second downlink packet to the user equipment by forwarding the second downlink packet to the second base station.

4. The method of claim 1 , further comprising:
reporting, by the first base station, to the network node a resource allocation at the first base station and the second base station.

5. The method of claim 1 , wherein the deviation comprises at least one downlink data packet being delivered to the user equipment via a base station that is different to what is marked in the at least one downlink data packet.

6. The method of claim 1 , wherein the first indication, the second indication, and the deviation enable the network node to determine charging for the at least one packet, the at least one other packet, the first downlink packet, and/or the second downlink packet.

7. The method of claim 1 , further comprising:
marking, by the first base station, one or more uplink packets to comprise a third indication to indicate that the second base station is no longer serving the user equipment.

8. An apparatus, comprising:
at least one processor; and
at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to:
mark, by the apparatus serving a user equipment, at least one packet to comprise a first indication indicating that the at least one packet was received directly at the apparatus serving the user equipment;
mark, by the apparatus, at least one other packet to comprise a second indication to indicate that the at least one other packet was received via a second base station also serving the user equipment;
receive, by the apparatus, a first downlink packet comprising a first downlink packet indication marked by a gateway node to indicate that at least the first downlink packet should be transmitted directly to the user equipment;
receive, by the first apparatus, a second downlink packet comprising a second downlink packet indication marked by the gateway node to indicate that at least the second downlink packet should be forwarded to the second base station for transmission to the user equipment; and
reporting, by the apparatus and to a network node, a deviation from a resource allocation and at least one of the first indication or the second indication.

9. The apparatus of claim 8 , wherein the apparatus comprises a first base station.

10. The apparatus of claim 8 , wherein the first indication and the second indication enable the network node to determine charging for the at least one packet, the at least one other packet, the first downlink packet, and/or the second downlink packet.

11. The apparatus of claim 8 , wherein the first downlink packet indication comprises a cell identifier associated with the first base station and/or a base station identifier identifying the first base station, and wherein the second downlink packet indication comprises another cell identifier associated with the second base station and/or another base station identifier identifying the second base station.

12. The apparatus of claim 11 , wherein the apparatus is further caused to at least send, based on the first downlink packet indication, the first downlink packet to the user equipment by transmitting the packet directly to the user equipment, and send, based on the second downlink packet indication, the second downlink packet to the user equipment by forwarding the second downlink packet to the second base station.

13. The apparatus of claim 8 , wherein the apparatus is further caused to at least report to a network node a resource allocation at the apparatus and the second base station.

14. The apparatus of claim 8 , wherein the deviation comprises at least one downlink data packet being delivered to the user equipment via a base station that is different to what is marked in the at least one downlink data packet.

15. The apparatus of claim 8 , wherein the first indication, the second indication, and the deviation enable the network node to determine charging for the at least one packet, the at least one other packet, the first downlink packet, and/or the second downlink packet.
