A congestion control mechanism is described that is specifically designed to enhance the operation of TCP communication sessions for the delivery of web content. The congestion control mechanism dynamically adjusts the size of the congestion window in a manner that maximizes the speed of content delivery for web page requests in a cellular network. The dynamic window size adjustments, including the initial congestion control window size, are adaptive, changing as cellular network conditions change, and in a manner that is not possible with conventional TCP congestion control mechanisms that were not explicitly designed to accelerate content in cellular networks. The congestion control mechanism also learns from previous experience with a particular end user device address and network, and applies its learning to set its initial values and subsequent behavior to more optimal levels for the particular end user device and network.

Dynamically optimized transport system

In general, techniques are described for emulating mobile authentication methods to establish authenticated connectivity between a mobile service provider gateway and a wireless device attached to an alternate access network. For example, a system operating according to the described techniques includes a mobile service provider network, an alternate access network having an access gateway, and an authentication server of the mobile service provider network that receives a network access request. A subscriber database responds to the network access request with virtual mobility information, wherein the network access request does not include an International Mobile Subscriber Identity (IMSI), and wherein the virtual mobility information comprises a virtual IMSI. The access gateway uses the virtual mobility information to signal a mobile network gateway of the mobile service provider network to establish a service session for the wireless device over the alternate access network that is anchored by the mobile network gateway.

Non-mobile authentication for mobile network gateway connectivity

In general, the invention is directed to techniques for offloading mobile data traffic from a mobile core network to a broadband network. For example, as described herein, a breakout gateway forwards a service request from a mobile device and addressed to a service node. The service node designates an access point name (APN) for offload such that data traffic associated with service requests specifying the designated APN is to be offloaded to an offload network. The service node receives the service requests from the breakout gateway and, if the service request specifies the designated APN, the service node sends a request to the breakout gateway. The breakout gateway receives the request and assigns a routable PDP address to the mobile device. An offload module on the breakout gateway redirects mobile data traffic to the offload network when the source PDP address of the traffic is the previously assigned PDP address.

Offloading mobile traffic from a mobile core network

A system is configured to: receive a message from a gateway device; identify one or more sessions corresponding to an identifier included in the message; and clear the one or more corresponding sessions. The identifier may correspond to a part of the gateway device where a session is stored or maintained for a mobile device to connect to a server device.
