Abstract

A method for network controlled optimization of hybrid access traffic management for a residential user connected via a hybrid access home gateway, which provides at least two different network links with different technology to a core network, wherein the core network has a connection to the internet, wherein in the core network a Hybrid Access Server is located, includes: extracting by the Hybrid Access Server one or more of the following information: Network link availability, Network link utilization, Quality of Service information with respect to the services requested from the home gateway; and selecting networks links, network traffic routing, and/or service routing by the Hybrid Access Server in communication with the hybrid access home gateway and/or other components in the network.

First claim

The invention claimed is:

1. A method for network controlled optimization of hybrid access traffic management for a residential user connected via a hybrid access home gateway using information available from fixed and mobile access and aggregation networks,
wherein the hybrid access home gateway provides at least two different network links corresponding to different technologies to a core network,
wherein the core network has a connection to the internet,
wherein a Hybrid Access Server is located in the core network,
wherein the Hybrid Access Server has a connection to the hybrid access home gateway via the at least two different network links,
wherein the Hybrid Access Server is connected to mobile network core components, components of a digital subscriber line (DSL) network, and components of the core network, and
wherein the core network, the Hybrid Access Server, the at least two different network links, the fixed and mobile access and aggregation networks, and the hybrid access home gateway are controlled by a network operator,
wherein the method comprises:
extracting, by the Hybrid Access Server, from the mobile network core components, information about network cells and information about occupation of the network cells;
extracting, by the Hybrid Access Server, from the components of the core network, information of services used by the hybrid access home gateway or quality of service (QoS) classes assigned to services used by the hybrid access home gateway;
extracting, by the Hybrid Access Server, from the components of the DSL network, information about DSL speed or workload of the components or the DSL network;
controlling, by the Hybrid Access Server, type and number of the network cells to which the hybrid access home gateway is connected: and
controlling, by the Hybrid Access Server, service routing for the hybrid access home gateway, including dynamic session or service category assignment for the at least two different links.

2. The method according claim 1 , further comprising:
adapting of transport network characteristics or content quality, wherein the adapting comprises one or more of the following steps: adapting of scheduling and prioritization in selected network segments, implementing of fairness or policies over a hybrid link, equalizing of link parameter and limitation of link parameter differences to achieve a more homogeneous appearance to higher network layers, and adapting of content quality to the performance of the hybrid link.

3. The method according to claim l, further comprising:
selecting, by the Hybrid Access Server, a cell based on an instantaneous or average load of the network cells to provide a maximum data rate or minimum response delay.

4. The method according to claim 1 , wherein the Hybrid Access Server in communication with the hybrid access home gateway is routing different services provided to the residential user over the at least two different network links to ensure quality demands of the services.

5. The method according to claim 4 , wherein voice calls are routed over the mobile network if the DSL network is used with a streaming service.

6. The method according to claim 1 , further comprising:
calculating, by the Hybrid Access Server, a long term prediction of parameters of the access channels or short term adaption based on the extracted information.

7. The method according to claim 6 , wherein a bandwidth is estimated by using or by requesting information from a mobile base station.

8. The method according to claim 1 , wherein when an end user requests a different or additional service the Hybrid Access Server triggers the hybrid access home gateway to change the routing over the at least two different network links.

9. The method according to claim 1 , wherein a scheduler of a mobile base station for a network link takes link quality of an other link, or a DSL link, into account.

10. The method according to claim 1 , wherein bonded links are set to parameters regarding throughput and delay.

11. The method according to claim 1 , further comprising:
improving perceptible quality by performing transcoding, which is controlled by a hybrid access link quality.

12. The method according to claim 1 , wherein within a link in the mobile network a handover between cells is performed based on an instruction of the Hybrid Access Server to establish a load balancing with respect to different cells.

13. A system for network controlled optimization of hybrid access traffic management for a residential user connected via a hybrid access home gateway using information available from fixed and mobile access and aggregation networks, the system comprising:
the hybrid access home gateway; and
a Hybrid Access Server;
wherein the hybrid access home gateway is configured to provide at least two different network links corresponding to different technologies to a core network, wherein the core network has a connection to the internet;
wherein the Hybrid Access Server is located in the core network;
wherein the Hybrid Access Server has a connection to the hybrid access home gateway via the at least two different network links;
wherein the Hybrid Access Server is connected to mobile network core components, components of a digital subscriber line (DSL) network, and components of the core network;
wherein the core network, the Hybrid Access Server, the at least two different network links, the fixed and mobile access and aggregation networks, and the hybrid access home gateway are controlled by a network operator;
wherein the Hybrid Access Server is configured for
extracting, from the mobile network core components, information about network cells and information about occupation of the network cells;
extracting, from the components of the core network, information of services used by the hybrid access home gateway or quality of service (QoS) classes assigned to services used by the hybrid access home gateway;
extracting, from the components of the DSL network, information about DSL speed or workload of the components of the DSL network;
controlling, by the Hybrid Access Server, type and number of the network cells to which the hybrid access home gateway is connected; and
controlling service routing for the hybrid access home gateway, including dynamic session or service category assignment for the at least two different links.
