Abstract: 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.

Abstract: In order to leverage an enterprise-hosted network (EHN) associated with an entity, a communication technique may dynamically customize an application on a portable electronic device. In particular, the portable electronic device may discover and then may connect to the EHN using a quarantine zone that restricts access to the EHN. After providing valid credentials to establish a level of trust with the EHN, the portable electronic device may receive a request for authentication and authorization information. In response to the request, the portable electronic device may provide a credential to the EHN. Next, the portable electronic device may receive provisioning information that customizes the application on the portable electronic device to a venue associated with the entity. The provisioning information may include a connection setting associated with the application on the portable electronic device, which allows the portable electronic device to connect to the EHN outside of the quarantine zone.

Abstract: Product or service information in the form of selected wireless e-commerce content is transmitted from a server to a mobile device, such as mobile telephone or personal digital assistant. The e-commerce content is transmitted either in response to an explicit user request for communication of the e-commerce content, or, in the alternative, is “pushed” to the mobile device as permitted by a user but in the absence of a specific request. The e-commerce content received at the mobile device is presented to a user by the mobile device in textual or graphical format in conjunction with an indication of a communication needed to consummate an e-commerce transaction. If the user desires to purchase the good or service represented by the e-commerce content, the user initiates the communication indicated by the e-commerce content.
