| 20110173209 | METHOD FOR LOSSLESS DATA REDUCTION OF REDUNDANT PATTERNS - The present application describes methods and systems for compressing and/or decompressing data. As blocks of data are processed, the processed blocks are placed into a circular buffer at a compressor and indexed based on patterns of data present in the processed blocks. A circular buffer is maintained at the decompressor so that the decompressor circular buffer is consistent with the compressor circular buffer. When a new block of data is processed, the compressor checks the index to the circular buffer to determine whether the new block of data contains a pattern that is redundant with a pattern in one or more blocks of data that have already been processed. If a redundancy is detected, the compressor informs the decompressor of the redundancy and provides information allowing the decompressor to reconstruct the redundant pattern from the decompressor's circular buffer. In this way, redundant data need not be retransmitted or stored. | 07-14-2011 |
| 20110170477 | MOBILE BROADBAND PACKET SWITCHED TRAFFIC OPTIMIZATION - A method in an electronic device and a system for use in a communication network including a core network and at least one access network are described. Intermediate service platforms in an access network process data bound from a base station towards a core network, and vice versa. A first data channel or stream is processed by the intermediate service platform. Exemplary embodiments bypass the intermediate service platform by intercepting a second data channel or stream bound for the intermediate service platform. The data in the second data channel or stream is processed and inserted into a data channel or stream downstream of the intermediate service platform. | 07-14-2011 |

| 20100057995 | CONTENT REPLACEMENT AND REFRESH POLICY IMPLEMENTATION FOR A CONTENT DISTRIBUTION NETWORK - A method for replacing, refreshing, and managing content in a communication network is provided. The method defines an object policy mechanism that applies media replacement policy rules to defined classes of stored content objects. The object policy mechanism may classify stored content objects into object groups or policy targets. The object policy mechanism may also define metric thresholds and event triggers as policy conditions. The object policy mechanism may further apply replacement policy algorithms or defined policy actions against a class of stored content objects. The media replacement policy rules are enforced at edge content storage repositories in the communication network. A computing device for carrying out the method, and a method for creating, reading, updating, and deleting policy elements and managing policy engine operations, are also provided. | 03-04-2010 |
| 20100057926 | DIGITAL CUSTOM DATA CONTENT INJECTION MECHANISM FOR A CONTENT DELIVERY NETWORK - A content selection and injection mechanism is provided for a communication network. In the communication network, an electronic device inserts custom data content into a data stream. The electronic device accepts a data stream from a location in the access network and identifies an insertion point suitable for inserting the custom data content into the data stream. The electronic device also selects the custom data content from a local content storage repository located in the access network, and inserts the custom data content into the data stream at the identified insertion point. The electronic device may identify a targeted user for receiving content, and select the custom data content based on the identity of the targeted user. | 03-04-2010 |
| 20100057883 | DISTRIBUTED CONTENT CACHING SOLUTION FOR A MOBILE WIRELESS NETWORK - A method in an electronic device provides local content to a user device in a communication network. The communication network includes an access network and a core network. In the access network, a content request is intercepted from the user device, which may be formatted according to a network interface. The content request may include a request for data content. Protocol layers associated with an active data session may be terminated so that an edge gateway device may extract and inject packets into the data stream without involving the core network. A cache may be maintained in the access network. | 03-04-2010 |
