Abstract: The invention relates to a method for commanding a security element of a mobile terminal, and to a mobile terminal. An installed application of the mobile terminal issues a command to a platform library of the mobile terminal. Then the platform library reads information from an access control file of the security element. After this, the platform library obtains an access code for the security element from a user according to the access control file information, and inputs the obtained access code and the command to the security element. An action is performed according to the command in the security element, if the access code is approved by the security element.

Abstract: A method of synchronizing timers in a wireless network is described. According to some embodiments, a master timer is sampled at the start time of a first beacon in a first data object and the sampled master timer value is broadcast in a second beacon of a second data object. A slave timer is sampled at the start of the second beacon in the second data object and a value representing the duration of the first data object is subtracted from the sampled slave timer value to determine an updated sampled slave timer value. According to some variations, a difference is determined between the sampled master timer value and the updated sampled slave timer value. The method then uses the difference to synchronize the slave timer to the master timer and to other slaver timers synchronized to the same master timer.

Abstract: A method in a communication network comprising a core network and a radio access network. At least one target cell is defined for at least one originating cell controlled by a first radio access network node. A request for a packet switched communication address of a second RAN node of the target cell is delivered to the second RAN node, and a response comprising the requested address is returned. The request and the response are transferred between the first radio access network node and the second radio access network node in information containers that are transparent to the core network. The received address information is stored in the first radio access network node for facilitating delivery of data packets between the originating cell and the target cell. Based on the stored cell-specific information, information may be exchanged between the nodes controlling the cells without congesting the essential core network elements and interfaces.

Abstract: A communication network includes a plurality of transceivers in spaced-apart locations A transmission from one of the transceivers to a selected receiver destination can be optimized by sending the transmission along optimum quality path segments from transceiver to transceiver. The optimum path segments are determined conveniently by comparing consecutive entries in a link quality table. Each transceiver may include a direction-agile antenna, which is oriented in the direction to optimize transmission and reception of each received data packet.

Abstract: A network-based wireless telephone communication device is proposed, which can be either an independent device or integrated to a portable information platform, and which is capable of providing an interactive multi-person voice communication session for the user to talk with one or more other persons via voice over a network system, such as the Internet, through a wireless network interface. The proposed network-based wireless telephone communication device is more advantageous to use than prior art in that it utilizes the Internet for voice data transmission and therefore is significantly more economical to use than mobile phone. Moreover, since the proposed network-based wireless telephone communication device can be either an independent device or integrated to a portable information platform, such as mobile phone, electronic dictionary, PDA, or the like, it has a higher level of portability than notebook computer with wireless linking capability.

Abstract: The present invention pertains to an apparatus and method for automatically disabling cell phone ringing and/or cell phone beeping. An RF transmitter is used to transmit an RF non-audible mode or control signal. Upon receiving the non-audible mode or control signal, the cell phone and/or beeper automatically disables its audible alarm. Users are notified of incoming calls and/or pages by means of blinking lights or vibration. When the user no longer receives the non-audible mode or control signal or upon the elapse of a fixed, pre-determined amount of time, the cell phone and/or beeper automatically reverts back to its normal mode of operation whereby incoming calls and pages are indicated by cell phone ringing and pager beeping.

Abstract: An adaptive control apparatus for keeping a dropping probability of a handoff call requested without user mobility information below a predefined level, to guarantee a quality of service (QoS). The apparatus adaptively controls an admission threshold of each cell in a wireless network to maintain the handoff dropping probability below a predefined level. The admission threshold is dynamically adjusted based on handoff drop events. The apparatus can guarantee QoS and maximize channel utilization. Since the apparatus is simply based on the handoff drop events of each cell rather than mobility of the respective calls, it is possible to remarkably decrease the complexity as compared with the existing mobile-oriented apparatus. In addition, the apparatus can solve the inter-cell unfairness problem.

Abstract: A satellite broadcasting system is disclosed wherein, when a broadcasting program is broadcast by satellite broadcasting, each viewer can receive a different broadcasting program depending upon the district in which the viewer is present. A broadcasting program is composed of an area designation part in which a list of areas in which the broadcasting program is to be broadcast is accommodated and broadcasting contents themselves. The broadcasting program is received by a radio wave reception section. A current position acquisition section detects the current position of a receiver. The current position is compared with an area to physical district coordination table and converted into an area name by a current area detection section.

Abstract: Transmission bandwidth consumption during the on-hold condition in telecommunications is reduced in a telecommunications system providing communication channels for the transmission of data between system stations. Two bandwidth states for each connecting channel are provided: an active state granting maximum bandwidth for the transmission of data and, for an on-hold condition, a minimal activity state for the connecting channel granting a minimal bandwidth. The active state prevails during the communication unless detecting means detect an on-hold condition in said connecting channel. Then, means responsive to a detection of on-hold condition switch to and provide a minimal activity state for said connecting channel granting a minimal bandwidth.

Abstract: A method and apparatus for estimating a communication channel in a wireless communication system having multiple transmitter antennas using reduced rank estimation. The method exploits redundant and/or a priori knowledge within a system to simplify the estimation calculations. In one embodiment, a covariance matrix is calculated and analyzed to determine if the channel parameters may be reduced for channel estimation. If not, all parameters are used, otherwise a reduced rank matrix is used for the calculation.
