Patent number: 11576112Abstract: During a communication technique, an access point provides a message that includes one or more public land mobile network identifiers of one or more cellular-telephone networks that are supported by the access point. Then, an electronic device, which received the message, provides a candidate list specifying one or more access points that support communication with a cellular telephone network to a radio node that is associated with this cellular-telephone network. By communicating with a wireless-local-area-network (WLAN) controller, the radio node validates the one or more access points, and selects a target access point based on performance feedback from the WLAN controller. Next, the radio node instructs the electronic device to associate with the target access point. Moreover, the radio node and the target access point establish a secure-communication pathway, which allows the radio node to communicate data to the electronic device via the access point using an LTE Wi-Fi aggregation protocol.Type: GrantFiled: April 26, 2021Date of Patent: February 7, 2023Assignee: ARRIS Enterprises LLCInventors: Steve A.
