Abstract: Methods, devices, systems, and non-transitory process-readable storage media of the various embodiments enable a software-enabled access point mobile computing device to delegate prefixes to already connected local area network (LAN) client devices upon establishment or re-establishment of a data connection. The various embodiments may enable a mobile computing device configured to operate as a mobile router (i.e., a softAP mobile computing device) to support prefix delegation by providing unique IPv6 prefixes to connected LAN client devices.

Abstract: Homes, enterprise establishments, and other facilities often have routing devices that route traffic to locally connected client devices. A routing device may be connected to an external network (e.g., the internet) through a bridging device, such as an outdoor unit that receives network connectivity through a cellular backhaul connection. If the bridging device's backhaul connection temporarily fails (e.g., due to radio link failure), a public IP address associated with the bridging device and the routing device may change upon recovery of the backhaul connection. If the routing device is not aware of the changed public IP address, subsequent communications between the routing device and the external network may fail. Disclosed are systems and methods for recovering from connectivity failure when using bridging devices to provide network connectivity.

Abstract: A method, an apparatus, and a computer program product for communication in a network. The apparatus sends a multicast message to a network device. The multicast message facilitates discovery of an unknown IP address of the network device. The apparatus determines whether a first response message is received from the network device in response to the multicast message and determines the IP address of the network device from the first response message when the first response message is received from the network device. The apparatus establishes a secure connection with the network device using the determined IP address. The apparatus sends a link status check message to the network device to detect a failed end-to-end link between the apparatus and the network device.

Abstract: Homes, enterprises, and other facilities often have routers that receive internet connectivity through wired remote network connections, and this connectivity is provided to locally connected client devices. Smart phones and other wireless devices can serve as mobile access points that receive internet connectivity through different remote network connections (e.g., cellular networks). The mobile access points may also service client devices that may be different from those serviced by the routers. When a mobile access point is placed in a facility having a router, the local networks of the mobile access point and the router may be merged. Disclosed are systems and methods for dynamically selecting from multiple host devices (e.g., the router and the mobile access point) to provide internet connectivity for merged networks.

Abstract: Methods, devices, systems, and non-transitory process-readable storage media include methods for preventing IPv6 address exhaustion in prefix delegation mode by a software-enabled access point (“softAP”) mobile computing device providing an Internet Protocol version 6 (IPv6) wide area network (WAN) connection to a plurality of client devices. A processor of a softAP mobile computing device may include assigning an unassigned prefix of a pool of available prefixes to a client device connected to a local area network (LAN) established by the softAP mobile computing device. The processor may determine whether the client device is disconnected from the LAN based on receiving an indication that the client device has disconnected. The processor may perform a cache look-up to obtain a link-local address of the client device when the client device is disconnected from the LAN, and unassign the prefix associated with the link-local address of the client device.
