20100098182 | Method and/or OFDM device for SC-FDMA data transmission - In a method and/or an OFDM device for SC-FDMA data transmission, a sequence of input data is transformed by means of a discrete transformation as transformed data signals of coded and modulated data signals on first frequency channels into a first frequency space over a first number of frequencies. The transformed data signals are mapped on second frequency channels in a second frequency space with a larger second number of frequencies. The transformed data signals on the second frequency channels are inverse-transformed using an inverse transformation. Data inversely transformed in such a way are provided for transmission. The transformed data signals are mapped into a frequency range of the second frequency channels in such a way that a constant component of the transformed data signals is mapped centrally within the frequency range. | 04-22-2010 |
20090307483 | METHOD AND SYSTEM FOR PROVIDING A MESH KEY - Method for providing a mesh key which can be used to encrypt messages between a first node and a second node of a mesh network, wherein a session key is generated when authenticating the first node in an authentication server, the first node and the authentication server or an authentication proxy server using a predefined key derivation function to derive the mesh key from said session key, which mesh key is transmitted to the second node. | 12-10-2009 |
20090222904 | NETWORK ACCESS NODE COMPUTER FOR A COMMUNICATION NETWORK, COMMUNICATION SYSTEM AND METHOD FOR OPERATING A COMMUNICATION SYSTEM - The invention relates to a network access remote front-end processor ( | 09-03-2009 |
20090219896 | FRAME AND CHIP OFFSET FOR SRNC IN UE INVOLVED RELOCATION ON CARRIER SHARING - This invention is related to a system and method to setup a radio link in a CDMA mobile communication network. In particular, a radio network controller (RNC) sends a radio link setup request message, and a processing device receives the radio link setup request message. The processing device sends a radio link setup response message to the RNC, and the response is received the RNC and includes frame and chip offset information. In particular, frame and chip offset in a RNSAP Radio Link Setup Response message (after execution of UE involved relocation) is conveyed. A new SRNC will then include a random frame offset in the RNSAP Radio Link Setup Request message. The eHSPA Node B will ignore the random frame offset, and include the correct frame offset in the RNSAP Radio Link Setup Response message. | 09-03-2009 |
20090196284 | Method for Providing an Emergency Call Service for VoIP Subscribers - A requirement for an emergency call is to reach the nearest emergency call centre and to transmit information to said centre concerning the location of the caller. However, a pre-defined assignment of the subscriber number of the VoIP subscriber is not necessarily given, as a VoIP subscriber can use the telephone service from any Internet connection. To solve this problem, the emergency call service is implemented by the local VoIP service provider responsible in the roaming network of the VoIP subscriber. | 08-06-2009 |
20090175280 | AUTOMATIC PACKET PROTECTION FORWARDING TO AN MPLS NETWORK BY A DUAL-HOMED ETHERNET BRIDGE - A method and a system for forwarding Ethernet packets by an Ethernet bridge (EB | 07-09-2009 |
20080293415 | Assembly Comprising a Cellular Network and at Least One Mobile Terminal, Method For the Operation of Such an Assembly, Mobile Terminal and Control Device - In order to be able to flexibly and dynamically control the selection of an access network to be used by a mobile terminal, an assembly contains a cellular network which is provided with a core network and several access networks for connecting mobile terminals to the core network, and at least one mobile terminal. The mobile terminal is equipped with a decision unit at the terminal end to select the access network to be used by the mobile terminal while the cellular network encompasses a decision unit at the network end to select the access network to be used by the mobile terminal as well as a control device for controlling the decision unit located at the terminal end and at the network end. | 11-27-2008 |
