Systems and methods are described for IP Address allocation. A computerized method includes receiving at a wireless access gateway a request from a subscriber to connect to a network, allocating a first IP address to the subscriber from a first pool of IP addresses at the wireless access gateway, and assigning a second IP address to the subscriber from a second pool of IP addresses at the wireless access gateway when the subscriber requests a network service.

IP address allocation

Systems and methods for managing packet flows in a communication network are provided. Packet information can be cached on different levels and used to avoid external queries. The cache information can also be correlated with other types of information, such as location information, to be able to serve that information quicker than if one or more external queries were to be made. A demux manager can provide routing and session setup, by routing packets that already have a session to the session manager and assigning packets to a session manager if they are not already assigned to a session. The tiered architecture also provides scalability to many users and minimizes delays even during high call volumes because the load can be distributed well across the gateway's resources.

Scalability of providing packet flow management

Described herein are techniques for providing a user device with a virtualized peering emulation service using an internet protocol (IP) connection between a sensor gateway (gateway) and a remote virtualized peering emulation service device (emulation device). The gateway receives wireless signals (e.g., Bluetooth, ZigBee, Z-Wave, and/or the like) from the user device. The gateway generates a data packet comprising data indicative of the wireless signals received from the user device and sends the data packet to the emulation device through the IP connection. The gateway receives network traffic through the IP connection from the emulation device, the network traffic comprising data indicative of wireless signals from a remote user device. The gateway transmits the wireless signals from the remote user device, such that the user device can locally receive the wireless signals from the remote user device, thereby providing a virtualized peering emulation service to the user device.

System and methods for providing virtualized cloud peering emulation services

Systems and methods are provided that allow inter-working between communication networks for the delivery of service to mobile nodes. A gateway is provided that communicates with a femto cell to extend service to an area that otherwise does not receive coverage from a service provider. The femto cell is a small scale base station used to provide coverage over a small area (such as a home or business), and connect to a home or enterprise network. The femto cell provides service for a mobile node and a gateway permits communication over a broadband network. The gateway integrates the mobile nodes connecting via a femto cell into the service provider's network. The gateway also allows provisioning of services and applications, control of service levels, and provides seamless handoffs to marco base stations and other types of access technologies such as Wi-Fi.

Apparatus, systems, and methods for providing interworking gateway

A method and system for automatically configuring and transforming a universal device into a feature specific device to provide desired network hardware functionality for a plurality of different conventionally single purpose devices. The universal device receives data configured for handling by a network hardware device capable of providing desired network hardware functionality. Based on the data received, the universal device identifies the desired network hardware functionality from network hardware functionalities. The universal device selects one or more virtual ports capable of providing the desired network hardware functionality. The universal device automatically configures and transforms itself into a feature specific device to provide the desired network hardware functionality by implementing the selected one or more virtual ports to handle the data received.

System and method for configuring a universal device to provide desired network hardware functionality

Described herein are techniques for providing carrier grade dynamic network address translation (NAT). The disclosed techniques allow for dynamic switching from regular NAT to network address ports translation (NAPT) based on system load. Under the NAPT mode, the disclosed techniques allow the ports of a public IP address to be broken up into contiguous blocks of ports (e.g., of the same size and/or of varying size) such that each block can be assigned to an associated (e.g., different) private IP address. For each new connection from the private IP address, if the port used is the next port sequentially, the NAT device can store an offset from the starting public/private IP address ports. If the port is not the next port sequentially, the network address translation device can associate a new block of public ports to the private IP address.

Carrier grade NAT

A management system implemented in a cloud computing environment for automatically managing a plurality of Wi-Fi access points in a network can receive information from each of the plurality of Wi-Fi access points. The system can analyze the received information from each Wi-Fi access point to determine at least one operation condition of at least one Wi-Fi access and determine at least one new operation setting for the at least one Wi-Fi access point based on the analyzed information. The system can remotely configure the at least one Wi-Fi access point based on the at least one new operation setting.

Cloud controller for self-optimized networks

Described herein are techniques for providing centrally managed Wi-Fi using internet protocol (IP) connections between a central Wi-Fi access gateway and one or more radio nodes. The Wi-Fi access gateway establishes an IP connection with a radio node across a wide area network, wherein the radio node is configured to wirelessly connect to one or more Wi-Fi devices located near the radio node. The Wi-Fi access gateway receives Layer 2 data traffic over the IP connection, wherein the Layer 2 data traffic is associated with a Wi-Fi device from the one or more Wi-Fi devices connected to the radio node. The Wi-Fi access gateway controls one or more Wi-Fi services for the Wi-Fi device based on the Layer 2 data traffic so that the Wi-Fi access gateway can provide centrally managed Wi-Fi for the Wi-Fi device.

Centrally managed WI-FI

Described herein are techniques for providing a virtual Wi-Fi service using internet protocol (IP) connections between a central Wi-Fi access gateway (WAG) and one or more radio nodes. The WAG establishes an IP connection with a first radio node across a network, where the first radio node is configured to connect to one or more Wi-Fi devices located near the first radio node. The WAG receives network traffic over the IP connection, where the network traffic is associated with a Wi-Fi device from the one or more Wi-Fi devices connected to the first radio node. The WAG provides a virtual Wi-Fi service through the network to the Wi-Fi device based on the network traffic such that the Wi-Fi device connects to the virtual Wi-Fi service as if the virtual Wi-Fi service is a physical device locally connected to the first radio node.

System and method of providing advanced services in a virtual CPE deployment

A combination cellular and Wi-Fi hardware device has an IP interface that is configured to communicate with a first cellular network, a Wi-Fi network, or both. The combination cellular and Wi-Fi hardware device is configured to provide the network functionality (e.g., virtualized network cloud) that is required to facilitate communication and data flow between the IP interface and either a second cellular network or a cloud computing infrastructure network. The IF interface is accessed using a single IP address by a mobile device in wireless communication with the combination cellular and Wi-Fi hardware device. The single IP address is maintained when the mobile device switches between using the first cellular network and the Wi-Fi network to communicate with the combination cellular and Wi-Fi hardware device, and vice versa.

Combination cellular and Wi-Fi hardware device
