20100034089 | Content Caching in the Radio Access Network (RAN) - A system and method to intercept traffic at standard interface points as defined by Cellular/Wireless networks (GSM/GPRS, 3G/UMTS/HSDPA/HSUPA, CDMA, WIMAX, LTE), emulate the respective protocols on either side of the interception point, extract user/application payloads within the intercepted packets, perform optimizations, and re-encapsulate with the same protocol, and deliver the content transparently is disclosed. The optimizations include but are not limited to Content Caching, prediction & pre-fetching of frequently used content, performance of content-aware transport optimizations (TCP, UDP, RTP etc.) for reducing back-haul bandwidth, and improvement of user experience. An additional embodiment of the current invention includes injecting opportunistic content (location based, profile based or advertisement content) based on the information derived while monitoring control plane protocols. | 02-11-2010 |
20100195602 | Application, Usage & Radio Link Aware Transport Network Scheduler - A packet scheduling method and apparatus with the knowledge of application behavior, anticipated usage/behavior based on the type of content, and underlying transport conditions during the time of delivery, is disclosed. This type of scheduling is applicable to a content server or a transit network device in wireless (e.g., 3G, WIMAX, LTE, WIFI) or wire-line networks. Methods for identifying or estimating rendering times of multi-media objects, segmenting a large media content, and automatically pausing or delaying delivery are disclosed. The scheduling reduces transit network bandwidth wastage, and facilitates optimal sharing of network resources such as in a wireless network. | 08-05-2010 |
20100261509 | Vibration Modulation Applications and Techniques in Mobile devices - Methods and applications for modulating the vibration mode of cellular handsets using patterned sequences are disclosed. This modulation allows additional information to be conveyed, thereby communicating messages in a variety of domains before the user responds to the vibration alert. This modulation may cause different patterns of vibration to convey additional information such as the importance of the call, identity of the caller, and other such information. The invention further extends vibration modulation to additional gaming and music & entertainment applications, such as rhythm synchronization, dance/step synchronization in a group, aerobic and other physical exercise related applications. | 10-14-2010 |
20110202634 | CHARGING-INVARIANT AND ORIGIN-SERVER-FRIENDLY TRANSIT CACHING IN MOBILE NETWORKS - A method for serving content from a radio-access network cache includes detecting a request from a mobile device for content in the cache. The request is sent to a content-origin server, and a response is received therefrom. | 08-18-2011 |
20120099533 | Content Caching in the Radio Access Network (RAN) - A system and method to intercept traffic at standard interface points as defined by Cellular/Wireless networks (GSM/GPRS, 3G/UMTS/HSDPA/HSUPA, CDMA, WIMAX, LTE), emulate the respective protocols on either side of the interception point, extract user/application payloads within the intercepted packets, perform optimizations, and re-encapsulate with the same protocol, and deliver the content transparently is disclosed.

20120184258 | Hierarchical Device type Recognition, Caching Control & Enhanced CDN communication in a Wireless Mobile Network - The present disclosure describes an apparatus and method for recognizing the mobile device type by information monitored from multiple means, such as by transparently monitoring Control Plane protocols, and monitoring user plane protocols (for example user agent header in HTTP protocols), and using such information for controlling data-caching operations, selectively delivering content, and selecting alternative interfaces/networks when available. Additionally, the invention discloses methods to propagate the learned information through header enrichment to external devices, such as content servers or CDN devices. The apparatus and methods are applicable to an application/content-aware caching device in a wireless mobile network that operates as an inline transparent device intercepting control plane and user plane protocols. | 07-19-2012 |

20140293875 | Radio Access Network Cache - A caching module is provided at the interface between a radio access network (RAN) and a core network (CN). If the requested content is available in the caching module as cached content, the caching module sends a header request upstream to an origin server to determine if the cached content is valid and authorized. If the cached content is invalid, it is evicted from the cached and may be replaced with a new, valid content. The CN can inspect the header response to perform data accounting and billing, to provide upstream content filtering, and to provide lawful interception capabilities. Related techniques are also provided. | 10-02-2014 |
