Abstract
A communication device and method for offloading communications from a first communication network to a second communication network. The offloading decision can be based on one or more parameters defined in a communication framework. The communication framework can be, for example, Access Network Discovery and Selection Function (ANDSF) framework. The offloading of communication can be from a Long-term Evolution (LTE) network to a Wi-Fi network, or vice-versa. The communication framework can include, for example, positional, movement, signal quality, connection duration, a data rate, and/or quality of service (QoS) parameters.
Claims20
A communication device, comprising:
- a first transceiver configured to communicate with a first communication network;
- a second transceiver configured to communicate with a second communication network;
- and
- a controller configured to:
- receive an offloading framework via the first communication network;
- and
- offload communications from the first communication network to the second communication network based on one or more communication parameters defined in the offloading framework,
- wherein the one or more communication parameters include a parameter that indicates a data rate validity condition for the second communication network, wherein the data rate validity condition defines a comparison of a data rate of an active connection of a second communication device on the second communication network with an estimated data rate of a prospective connection of the communication device on the second communication network.
A communication method, comprising:
- receiving an offloading framework via a first communication network, the offloading framework defining one or more communication parameters;
- determining operational information of a communication device configured to operate in the first communication network;
- and
- offloading communications from the first communication network to a second communication network based on a comparison of the operational information and the one or more communication parameters of the offloading framework,
- wherein the one or more communication parameters include a parameter that indicates a data rate validity condition of the second communication network, wherein the data rate validity condition defines a comparison of a data rate of an active connection of a second communication device on the second communication network with an estimated data rate of a prospective connection of the communication device on the second communication network.
