20080200147 | Authentication of Mobile Communication Networks - A mobile station is adapted to communicate with a core network portion of a mobile communications network via an unlicensed radio access network. The mobile station has a SIM card adapted to generate a unique response word using at least a key unique to the mobile station and a fixed length random number. The mobile station includes processing circuitry and unlicensed radio interface circuitry coupled to the processing circuitry. This circuitry is adapted to generate a fixed-length random number, calculate a first response word with the SIM card on the basis of the generated random number, formulate and transmit an authentication request to the unlicensed radio access network containing the fixed-length random number, receive an authentication response from the unlicensed radio access network containing a second response word, and compare the calculated first response word with the received second word to authenticate said core network. In this manner, mobile station is able to authenticate the network with an existing second-generation SIM card and with minimum modification of its operation. | 08-21-2008 |
20080212593 | Automatic Adaptation of Quality of Service Over Packet-Switched Networks - An end node in a packet-switched network is proposed wherein the end node is arranged to exchange packets consisting of a packet header and payload data with a server node connected to the packet-switched network. The end node includes at least one module adapted to extract quality of service parameter values from the headers of packets received over the packet-switched network and to insert the extracted quality of service parameter value in the headers of packets destined for transmission to the server node over the packet-switched network. In this manner the end node automatically adapts the quality of service parameters received over the packet-switched network to correspond with the type of quality of service defined in received packets. Such a system means that only the server node need be configured with the quality of service parameters applicable on the particular packet switched network, so greatly reducing the installation and configuration overheads in a multi-user network. | 09-04-2008 |
20080227468 | Location Control in a Mobile Communications Network - The present invention relates to an improved location process for determining the location of mobile stations when a GSM network is extended by other access networks, for example unlicensed radio access networks.

By providing the location service entities with information on the location methods to use, there is no need to configure the location service entities with this information in advance. Moreover, the process is flexible and can be tailored to the network element making the request and thus to the type of connection actually used by the mobile station. There is no need for the location entities to launch several location methods before retrieving sufficiently accurate information since the most suitable methods are communicated in advance. | 09-18-2008 |

20110090864 | Method and apparatus for facilitating handover from a WCDMA public land mobile access network to a generic access network - Handover is improved from a 3 G WCDMA UTRAN to a generic access network (GAN) cell. For handover, mobile stations measure signal level from neighbor cells. In a WCDMA UTRAN, measurement of cells having a frequency number different from the serving cell, require the network to generate time gaps so the mobile station can perform measurements on different frequencies.
