| 20100306386 | PARAMETERIZABLE SELECTION OF A COMMUNICATION SYSTEM ON THE BASIS OF NAME RESOLUTION MECHANISMS - The invention relates to a method for establishing a communication link between a communication system and a remote station by means of a communication network, whereby, in the context of the communication link, a parameterized selection of a remote station is made from several available remote stations by utilizing the name resolution mechanism. The communication forms a logical name with the help of parameters used for selecting a remote station or embeds the parameters in a logical name and transmits the formed logical name to a name resolution mechanism located in the communication network. The name resolution mechanism selects a remote station on the basis of the afore-mentioned logical name and a selection function and feeds back the communication address thereof. | 12-02-2010 |
| 20100303010 | CIRCUIT-SWITCHED CALL CONTROL VIA AN IP USER CHANNEL CONNECTION IN THE ACCESS NETWORK - The invention relates to a method for implementing call control in packet-switched networks, wherein a connection is established between two communications partners by means of static multiplexing in a network and the use of the network for telephone services on an application level, causing signaling between two participating terminal devices. In the course of the general development of the internet, it seems reasonable for operators of conventional telecommunications networks to operate their telephone services via packet-switched networks. However, the establishment of a completely new SIP-based protocol world is disadvantageous for an operator that wishes only to continue its known telephone services. As a result, the operator has the aim of enhancing the transfer of protocols such that the protocols known from circuit-switched technology may be transferred in a simplified fashion to packet-switched networks. Said aim is achieved in that a user channel is configured in the packet-switched access network, wherein call control occurs by means of a circuit-switched signaling via the IP user channel. | 12-02-2010 |
| 20100299755 | ANTI-VIRUS/SPAM METHOD IN MOBILE RADIO NETWORKS - The invention concerns a process to protect against viruses/spam in mobile broadcast networks containing convergent messaging services with transmission of protocol data, characterized by having functions included in the protocol of the convergent messaging service, which facilitate the exchange of virus/spam information between the network components of one or more network operators.

| 20100296729 | METHOD FOR IMAGE ANALYSIS, ESPECIALLY FOR MOBILE STATIONS - A robust OCR system requiring little computing capacity is obtained by first carrying out an adaptive pre-processing optimised in terms of pixel groups, which analyses the image in line segments. The most significant difference compared to previously known methods is that there is no longer a direct pattern comparison, instead the line segments are gone over in as optimum a manner as possible. The corresponding character is then deduced from the sequence of movements. As this sequence of movements can be scaled well and described in a relatively simple manner, this technique is especially suitable for mobile use. The sequence of movements of know characters is stored in a search word, such that the letters can be directly deduced from the movement. A dictionary/lexicon can also be used. If words are recognised by means of the dictionary/lexicon, the recognised letters can be used for an even more optimised character font identification. The invention is advantageous in that a robust OCR system is provided, which also requires little computing capacity. The system according to the invention is robust especially in that the recognition works better than with conventional systems even under bad conditions, especially light ratios and interferences. | 11-25-2010 |
| 20100210271 | METHOD FOR PREVENTING PING-PONG HANDOVER IN MOBILE RADIO NETWORKS - A method for preventing ping-pong handover in mobile radio networks having a multiplicity of stationary base stations at a distance from one another, and also stationary and/or moveable mobile radio stations, such as mobile radio telephones, which are in the transmission and reception range of the base stations. Repeated unwanted handover of a mobile radio station in the connected/active mode from a source base station to a destination base station is reduced or prevented. System messages are transmitted between the mobile radio stations and the base station, wherein the system messages for initiating the handover are used to transmit historical information relating to handovers which have already been performed, that information being used to automatically ascertain and set optimum operating parameters for the mobile radio stations and/or at least one of the base stations which are involved. The aim is to develop a method for preventing ping-pong handover in mobile radio networks, specifically in networks with network elements from different manufacturers, such that the parameters, particularly the hysteresis of the reception field strength, of the mobile radio and/or of the base stations are automatically set independently, to prevent ping-pong handover, without the need for expensive measurement trips with “manual” measurements. | 08-19-2010 |
| 20100210261 | METHOD FOR ENSURING THE ACCESSIBILITY OF MOBILE RADIO DEVICES USING AN OPTIMIZED PAGING MECHANISM - The invention relates to a method for performing a paging call in a cellular mobile communications system, wherein a terminal device is operated in a first radio cell of the mobile communications system provided with radio signals from a radio transmission device, said terminal device being in an idle state, and data to be transmitted to the terminal device are present in a data transmission device of the mobile communications system. The invention is characterized in that upon detection of a loss of service or fault in the radio transmission device, measures for handling the loss of service/fault in said radio transmission device are taken, with the goal of restoring the accessibility of the mobile radio device for which said radio transmission device is the last known radio transmission device. | 08-19-2010 |

The invention is characterised in that the interface uses a communication node or group system as computer and carries out a communication in a transmission channel with automatic directional switching in an analogue or digital telephone network in the direction of an available Push-to-Talk server, the analogue or digital telephone network being designed as an audio and control interface in the direction of the operating means. | 07-08-2010 |
| 20100124926 | METHOD FOR CONSIDERING THE SUBSCRIBER TYPE IN MOBILITY AND RADIO RESOURCE MANAGEMENT DECISIONS IN A RADIO ACCESS NETWORK - In order to efficiently allow mobility and radio resource management decisions on mobile networks the deciding entity (typically the radio access network) needs some understanding about the type of mobile user. In current cellular systems the radio network has only limited to null information about subscription dependent details of the mobile users. The proposed invention relates to a mobile system where a generic information container is defined which is applicable per UE in order to convey subscription related information from the core network to the radio access network which can be used to steer the user to an appropriate cell or for any other Radio Resource Management (RRM) related procedure/decision. It is proposed to define an information element (herein referred as “subscriber type”) which allows an indication or pointer to a set of rules which are locally defined in involved no'des (e.g. CN SGSN, MSC, routers etc) and describe the “handling rules” to be applied in the RAN for each user of the mobile system independently. | 05-20-2010 |
