| 20110107082 | Storing and Forwarding Media Data - A method apparatus for storing and forwarding media data in a communication network. An intermediate node disposed between a media data source node and a client node receives encrypted media data packets from the media data source node. The intermediate node stores the received media data packets in a memory for later sending to the client node, and adjusts fields in the original header of each stored media data packet to create modified media data packets having a modified header, and sends adjustment information to the client node. The adjustment information allows the client node to recreate the original headers from the modified headesr, before decrypting the encrypted media packets with keying materials already sent between the media data source node and the client node. The modified media data packets are then sent to the client node for decryption.

| 20090052327 | End-to-end considerate link control and routing in a multihop network - By introducing a novel parameter common to all links along the entire multihop route it is possible to more flexibly allocate, for each of a number of the links, a set of three interdependent link transmit parameters representative of link transmit energy, link transmit time or link transmit bandwidth or link code word consumption, and link transmit power. Basically, the common parameter is determined based on a given end-to-end (ETE) transmit parameter constraint for the entire multihop route. The idea is then to assign or allocate, for each considered link, the three interdependent link transmit parameters based on the common parameter and local link characteristics. In this way, all three link transmit parameters may (and generally will) be different between at least two links on the route when the links have different link characteristics, assuming that each link transmit parameter is also dependent on the local link characteristics. Preferably, the common parameter is determined in the process of optimizing a given objective ETE function. | 02-26-2009 |

A caller places a call to a subscriber through a serving network using the flexible subscriber number. The flexible subscriber number is translated into a primary MSISDN and the call is connected to the subscriber so that roaming charges to the subscriber are minimized. | 01-08-2009 |
| 20080301515 | Method and a Transmitter/Receiver for Reduced Signaling in a Retransmission System Using Hybrid Automatic Repeat - The present invention relates to a transmitter and a receiver for a mobile communication system. The basic idea of the present invention is to target the number of HARQ transmissions that is required to be able to decode the transmitted data successfully and to only transmit HARQ feedback information if the decoding result differs from an expected result, wherein the expected result is based on the targeted number of required HARQ transmissions. | 12-04-2008 |

| 20080267265 | Robust Multicode Detector for HSDPA - Detecting a symbol of interest comprises despreading a received signal to obtain despread values corresponding to the symbol of interest and to one or more interfering symbols, combining the despread values to generate combined values for the symbol of interest and the interfering symbols, computing spreading waveform correlations between the spreading waveform for the symbol of interest and the spreading waveforms for the interfering symbols, computing interference rejection terms representing the interference present in the combined value for the symbol of interest attributable to the interfering symbols based on the spreading waveform correlations, and generating an estimate of the symbol of interest by combining the combined values with the interference rejection terms. The interference rejection terms are computed by scaling the spreading waveform correlations by corresponding signal powers and compensating the estimates for noise. This provides a robust interference model that avoids numerical problems associated with conventional joint detection. | 10-30-2008 |
| 20080256272 | Packet Scheduling for Data Stream Transmission - The invention relates to transmitting data elements of a data stream based on a priority and target buffer fill levels at a receiving device. A transmitter controller transmits data elements of a data element class with a highest priority first, for reaching an associated buffer fill level and then turns to data elements of successively lower priorities, until the available bandwidth is exhausted. | 10-16-2008 |
| 20080256091 | Prioritising Data Elements of a Data Stream - The invention relates to prioritising of data elements of a data stream for transmission to a receiving device including determining a decodability of data elements, wherein the decodability indicates the extent to which the current data element is decodable at the receiving device. Then, a priority is assigned to the data elements based on the determined decodabilities. A transmission of the data elements to a receiving device is then scheduled based on the priorities. | 10-16-2008 |
| 20080215888 | Method and Arrangement For Authentication and Privacy - The present invention improves privacy protection and authentication over prior art GAA/GBA system specifying a Bootstrap Server Function (BSF) that creates an Authentication Voucher asserting to a network application function NAF authentication of a. BSF generates keys Ks and Ks NAF with corresponding key identifiers B_TID and B_TID_NAF. In order to prevent tracking of user by collusion between several NAF entities B_TID_NAF and the Voucher can be unique for each NAF. The interface Ua is further protected by encryption using key Ks and the Ub interface is further protected against man-in-the-middle attacks by using signatures with key Ks and provision of freshness. | 09-04-2008 |

| 20080198554 | Cooling Assembly - A cooling assembly and method of cooling a heat-generating electronic component on a circuit board. A heat collector collects heat from the electronic component. A heat pipe transfers the heat to a location remote from the electronic component. A heat sink is mounted to the circuit board at the distant location. The heat sink has at least one groove formed on an underside thereof. The heat sink is mounted so that is overlies the heat pipe and the heat pipe is introduced into the groove, thereby securing the heat pipe between the heat sink and the circuit board. | 08-21-2008 |
