Disclosed embodiments include a method for synchronizing a cryptosystem. In one embodiment, the method uses existing control data that is transmitted as part of a connection establishment process in a wireless communication system. In one embodiment, messages that are normally sent between a base station and a remote unit during the setup of both originating and terminating calls are parsed to detect a particular control message that indicates the start of telephony data transmission. Detection of this message indicates a point at which encryption/decryption can begin, and is used to synchronize the cryptosystem. Synchronizing a cryptosystem involves generating an RC4 state space in a keyed-autokey (“KEK”) encryption system. In one embodiment, Lower Medium Access Channel (“LMAC”) messages are used according to a wireless communication protocol. This is convenient because the LMAC messages are passed through the same Associated Control Channel (“ACC”) processing that encrypts and decrypts the telephony data.

Architecture that facilitates initiation of a user feedback signal during a telephone call when perceiving reduced voice quality. In response to receiving the feedback signal, the telephone network performs a number of measurements on the system and related to the user device that can be analyzed to determine the problem, and potentially resolve the problem. The feedback signal can be initiated by any number of user input means, including selection of a key or combination of keys on a cell phone keypad that generate signals which can be interpreted by the telephone network as the feedback signal, e.g., a DTMF signal.

A mobile terminal device that facilitates location services (LCS) in a cellular network. The system, as embodied in a mobile terminal device, comprises a mobile communications component that communicates wireless signals, and a location services component embodied in the mobile communication component to provide positioning information. A location request is received by the mobile terminal device and processed using the LCS server to activate trigger events. A location-tracking report is autonomously generated for each event and transmitted to the requesting client via MLP or the wireless network signaling protocol.

An analog telephone adapter (ATA) having a subscriber identity component in the format of a Subscriber Identity Module (SIM) that couples a telephone to a cellular network via Voice over Internet Protocol (VoIP), thereby allowing a cellular service provider to provide an alternative communication service for the home or business. Instead of using the plain old telephone service, a subscriber can plug their analog telephone into the SIM-enabled ATA (SIM-ATA) and receive telephone service from a cellular service provider, eliminating or reducing the need for a traditional Local Exchange Carrier. The SIM-ATA converts signals from analog to digital, and vice-versa. Once the analog telephone signal has been converted to digital, an IP-based protocol (e.g., VoIP) can be used to transmit the telephone call over a digital network. The cellular service provider can then track usage and bill the subscriber accordingly.

A method provides for an improved compensation Fourier channel characteristics in a wireless communication embodiment. The method identifies one or more information carriers as pseudo pilot tones whose information may be realized to enhance the determination of the complex coefficient of the communication channel.

A method and system automatically activates a mobile station in a wireless communications network. The system includes an over the air activation function (OTAF) processor in the network that initiates an activation process in response to receiving a registration message from a mobile switching center serving the mobile station requesting the activation. Each mobile station has a unit of information stored into it at the time of its manufacture to enable it to request over the air activation. That unit of information is either the network routing address of the OTAF processor, or alternately, it is a value that is translatable into that address, either an OTAF ID number that is the same value for every mobile station or it is a sequentially serialized dummy value for the mobile identification number (a dummy MIN). When the mobile station is turned on for the first time in the network, it requests activation over the air by transmitting to the local mobile switching center a registration order. The registration order will include one of the three alternative forms of the information unit described above, either the routing address of the OTAF processor, or the OTAF ID number, or a dummy MIN.

A mobile station communicates with both a cellular network, by which it is assigned a mobile identification number, and to a cordless cellular base station utilizing the same cellular frequency range and communications protocol. The cordless cellular base station is preferably connected to a public switched telephone network and is assigned a landline number. The cordless cellular base station acts as a conduit between the mobile station and the public switched telephone network. When the mobile station comes within range of a cordless cellular base station, it deregisters automatically from the cellular network and register with the cordless cellular base station. Once the mobile station is communicating with the cordless cellular base station, the cordless cellular base station communicates with the cellular network to instruct the cellular network to route all calls for mobile identification number to the cordless cellular base station's landline number. In addition, all calls placed on the mobile station are sent through the cordless cellular base station to the public switched telephone network. When the mobile station severs contact with the cordless cellular base station, the mobile station registers with the regional cellular base station of the regional cellular network. The cordless cellular base station then sends a network forwarding cancellation message to the cellular network to cancel the forwarding of calls for the mobile station's identification number. Once the mobile station is registered with the regional cell, calls to the mobile stations identification number are directly routed by the cellular network to the mobile station.

A put transaction is intercepted and communicated from an application to a database driver. The transaction is committed to a target database of the transaction and a backup database of the target database when both the target database and the backup database are available. When one of the target database and the backup database is an unavailable database, the transaction is recorded in a file. When the unavailable database becomes an available database, the transaction is committed to the available database.

The present invention relates to hotline routing of calls originating from mobile stations. The hotline routing conserves MSISDNs for valid subscribers and provides a relatively generic solution. In one example, a computer system stores in a location register a subscriber profile with an IMSI and a pseudo-MSISDN. A mobile station (which includes a SIM with the IMSI) originates a call. After translation of the pseudo-MSISDN, a serving MSC routes the call to a service activation center.
