Data flow manager for distributing data for a data stream of a user equipment, communication system and method

A communication system, comprising:

• a first network access entity for providing a network access via a first communication link to a communication network for a home gateway;
• a second network access entity for providing a network access via a second communication link to the communication network for a user equipment;
• the home gateway, wherein the home gateway is configured to connect to the communication network via the first communication link;
• and
• the user equipment, wherein the user equipment is configured to connect to the home gateway via a third communication link;
• wherein the first communication link and the third communication link form a composite communication link,
• wherein the user equipment is configured to simultaneously communicate over the composite communication link and the second communication link;
• and
• wherein the communication system further comprises a data flow manager, the data flow manager comprising:
• a network interface configured to receive a first status signal indicating a link quality of the first communication link, a second status signal indicating a link quality of the second communication link and a third status signal indicating a link quality of the composite communication link;
• and
• a processor configured to, if at least one of the first status signal or the second status signal indicates a higher link quality than a link quality that is indicated by the third status signal, determine a reduction of an amount of data of the data stream communicated over the first communication link and an increase of an amount of data of the data stream communicated over the second communication link.

A method for assigning data of a data stream of a user equipment via a first communication link and via a second communication link, the first communication link connecting a home gateway to a first network access entity that provides access to a communication network for the home gateway, the second communication link connecting the user equipment to a second network access entity that provides access to the communication network for the user equipment, the user equipment being further connected to the home gateway via a third communication link, the first communication link and the third communication link forming a composite communication link, the user equipment being configured to simultaneously communicate over the composite communication link and the second communication link in a communication network, the method comprising:

• receiving a first status signal, a second status signal and a third status signal, the first status signal indicating a link quality of the first communication link, the second status signal indicating a link quality of the second communication link, and the third status signal indicating a link quality of the composite communication link;
• and
• if at least one of the first status signal or the second status signal indicates a higher link quality than a link quality that is indicated by the third status signal, determining a reduction of an amount of data of the data stream communicated over the first communication link and an increase of an amount of data of the data stream communicated over the second communication link.
