International Classification:

H04W 24/00

US Classification:

370252

Abstract:

The present invention identifies methods and procedures for correlating control plane and user plane data, consolidating and abstracting the learned and correlated data in a form convenient for minimizing and exporting to other network devices, such as those in the Core Network and the Access Network, or the origin server, CDN devices or client device. These correlation methods may use Control Plane information from a plurality of interfaces in the RAN, and User plane information from other interfaces in the RAN or CN. IF the device is deployed as an inline proxy, this information may be exported using in-band communication, such as HTTP extension headers in HTTP Request or Response packets, or another protocol header, such as the IP or GTP-U header field. Alternatively, this information can be exported out-of-band using a separate protocol between the RAN Transit Network Device (RTND) and the receiving device.

International Classification:

H04W 28/10

US Classification:

370235

Abstract:

A system and methods for application control which enable the delivery of Rich Internet Applications such as HD/Video Stream, Gaming, and Webservice delivery over mobile operator's PLMN is disclosed. The methods define Application Program Interfaces for Application Service Providers for delivering rich applications such as NetFlix Video service, Interactive Network Gaming etc., over wireless mobile network using state of the art web protocols such as HTTP, RTMP etc. The platform that incorporates these methods interacts with 3GPP/UMTS/LTE/CDMA defined standard compliant network devices using the standard network interfaces and present application specific control function. It further identifies extensions to the logical interfaces defined by the corresponding standards (3GPP, 3GPP2 etc.). Additionally, methods and procedures for controlling QoS in the transit network gateways, such as SGSN, GGSN, or P-GW, while delivering application traffic, are also disclosed.

International Classification:

H04W 36/00

H04W 36/04
H04W 84/04
H04W 88/10

Abstract:

In an example, a wireless communication system and apparatuses thereof are described. In an example long-term evolution (LTE) network, a first base station hands over a connection to a second base station. The first base station may be a (femto) home eNodeB (HeNB) or (macro) eNodeB. The second base station may also be a HeNB or eNodeB connected to a different gateway. The first base station may send “Handover Request” on an X2 connection, identifying the gateway that the second base station is connected to as the correct gateway. After sending a “Handover Request Acknowledgement,” the second base station correctly establishes a tunnel to a connected gateway device.
