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. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The communication device of claim 1, wherein the offloading framework conforms to an Access Network Discovery and Selection Function (ANDSF) framework. ### Claim 3 (depends on 1) The communication device of claim 1, wherein the one or more communication parameters include a parameter that defines a movement state of the communication device. ### Claim 4 (depends on 3) The communication device of claim 3, wherein the movement state includes at least one of: a Pedestrian-A movement state, a Pedestrian-B movement state, and a Vehicular-A movement state. ### Claim 5 (depends on 1) The communication device of claim 1, wherein the one or more communication parameters include a parameter that defines a received signal strength indication (RSSI) threshold or a signal-to-interference-plus-noise ratio (SINR) threshold for the second communication network. ### Claim 6 (depends on 1) The communication device of claim 1, wherein the one or more communication parameters include a parameter that defines a time duration that the communication device or another communication device has previously remained connected to the second communication network. ### Claim 7 (depends on 1) The communication device of claim 1, wherein the one or more communication parameters include a parameter that defines 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 communications device on the second communication network with an estimated data rate of a prospective connection of the communications device on the second communication network. ### Claim 8 (depends on 7) The communication device of claim 7, wherein the controller is configured to compare the data rate to the estimated data rate, and offload the communications from the first communication network to the second communication network based on the comparison. ### Claim 9 (depends on 8) The communication device of claim 8, wherein the estimated data rate is estimated by an access point supporting the second communication network. ### Claim 10 (depends on 1) The communication device of claim 1, wherein the one or more communication parameters include a parameter that defines Wi-Fi multimedia (WMM) mapping of the second communication network. ### Claim 11 (depends on 1) The communication device of claim 1, wherein the WMM mapping includes at least one of packet priority information, packet error loss rate information or packet delay budget information. ### Claim 12 (depends on 1) The communication device of claim 1, wherein the first communication network is a Long-Term Evolution (LTE) communication network and the second communication network is a Wi-Fi communication network. ### Claim 13 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. ### Claim 14 (depends on 13) The communication Method of claim 13, wherein the offloading framework conforms to an Access Network Discovery and Selection Function (ANDSF) framework. ### Claim 15 (depends on 13) The communication method of claim 13, wherein the one or more communication parameters include a parameter that defines a movement state of the communication device. ### Claim 16 (depends on 13) The communication method of claim 13, wherein the one or more communication parameters include a parameter that defines a received signal strength indication (RSSI) threshold or a signal-to-interference-plus-noise ratio (SINR) threshold of the second communication network. ### Claim 17 (depends on 13) The communication method of claim 13, wherein the one or more communication parameters include a parameter that defines a time duration that the communication device or another communication device has previously remained connected to the second communication network. ### Claim 18 (depends on 13) The communication method of claim 13, wherein the one or more communication parameters include a parameter that defines a data rate validity condition of the second communication network. ### Claim 19 (depends on 13) The communication method of claim 13, wherein the first communication network is a Long-Term Evolution (LTE) communication network and the second communication network is a WiFi communication network. ### Claim 20 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 Access Network Discovery and Selection Function (ANDSF) framework via the first communication network, the ANDSF framework including a movement parameter, a signal quality parameter, a connection duration parameter, a data rate parameter, and a quality of service (QoS) parameter;
