International Classification:

H04L 43/0823
H04L 47/11
H04W 24/02
H04L 69/16

Abstract:

Various embodiments comprise systems, methods, mechanisms, and apparatus by which a network operator such as a wireline internet service provider (ISP) may determine that an endpoint device has one or more other wireless devices tethered to it, such as a mobile handset providing dual-Wi-Fi ad-hoc tethering (i.e., connected to a high-speed Wi-Fi network while simultaneously providing Wi-Fi connections to wireless devices tethered to the mobile handset), by monitoring Transmission Control Protocol (TCP)/IP traffic flow associated with endpoint devices (i.e., to or through endpoint devices), characterizing these traffic flows in accordance with one or more error indicative criteria to establish thereby a baseline profile of error indicative criteria that is indicative of a TCP/IP traffic flow associated with an endpoint device that is not associated with tethering (e.g., a rate or number of duplicate ACKs), wherein deviations from the baseline profile of error indicative criteria beyond a threshold are indicative of a TCP/IP traffic flow associated with an endpoint device that is associated with tethering.

International Classification:

H04W 48/08
H04L 29/08

Abstract:

Systems, methods, and devices for instantiating both a private network service (PrNS) gateway virtual network function (VNF) and a public network service (PuNS) gateway VNF for a user equipment (UE) device that is associated with a PrNS and communicatively attached a public WiFi network allow users to access the same set of feature-rich network services (including layer 2 services) when connected through a public hotspot WiFi network as when connected through a home or local area network WiFi network.

International Classification:

H04L 29/12
H04L 12/66
H04L 12/911

Abstract:

Systems, methods, and devices for performing targeted filtering of network traffic generated by user equipment (UE) devices connected to a customer premise equipment (CPE) device in a communication system that includes a distributed residential gateway. A network server may determine that the communication system includes a UE device that is compromised, misconfigured, or operating outside normal communication parameters, identify the UE device, determine an Internet protocol (IP) address or a media access control (MAC) address of the identified UE device, generate a quarantine request message that includes the IP address or the MAC address of the identified UE device in response to determining that the preconfigured virtual local area network access control list (VACL) on the CPE lists source IP addresses from which the CPE will filter outbound traffic, and send the generated quarantine request message to a bridged residential gateway (BRG) associated with the CPE device.

International Classification:

H04L 12/24
H04L 12/66
H04L 29/12

Abstract:

Automatic local gateway router backup of a network gateway router is disclosed. A local gateway router communicatively coupled to a local subnet determines that a network gateway router that serves as a default gateway router for the local subnet has stopped responding. The local gateway router and the network gateway router are configured to communicate with one another via a tunnel implemented by a tunneling protocol. In response to determining that the network gateway router has stopped responding, automatically switching, by the local gateway router, from a tunneling mode to a routing mode, such that the local gateway router becomes the default gateway router for the local subnet.

International Classification:

H04L 29/12

H04L 12/911

Abstract:

Systems, methods, and devices for performing targeted filtering of network traffic generated by user equipment (UE) devices connected to a customer premise device (CPE) in a communication system that includes a distributed residential gateway. A broadband network gateway may be configured to identify a UE device in a local area network (LAN) associated with the CPE that is compromised, misconfigured, or operating outside normal communication parameters. The broadband network gateway may send a dynamic host configuration protocol (DHCP) force renew message via a wide area network (WAN) to the identified UE device in the LAN, generate a DHCP offer message that presents a new Internet protocol (IP) address assignment that is within a range of IP addresses included in a layer 2/3 access list, and send the generated DHCP offer message to the UE device to quarantine the UE device.

International Classification:

H04L 29/06

H04W 4/14

Abstract:

According to one configuration, a wireless access service provider selects and assigns a particular authentication option amongst multiple different authentication options to an entity such as a wireless access point or a sub-network supported by the wireless access point. When a communication device attempts to use the corresponding wireless access point provided by the wireless access service provider, a wireless access gateway receives information from the wireless access point indicating the particular authentication option assigned to authenticate the communication device. The wireless access gateway communicates the notification of the particular authentication option to an authentication manager, which provides the wireless access gateway with network address information indicating a captive portal in which to authenticate the communication device. The wireless access gateway then uses the network address information to redirect the communication device to the captive portal, which is then used to authenticate the communication device. to access the Internet.
