Abstract: A method and system for transmitting a voice message to an electronic address, generally includes establishing a data connection between a first server of a voice messaging system and a wireless device so as to enable a user to access an electronic mail account. The first server then captures a wireless device identifier and accesses an association of the wireless device identifier to a telephone number of the wireless device. A call is then initiated from the wireless device to a second server of the voice messaging system to record a voice message. The previously stored recipient electronic address is retrieved using the captured telephone number and an email including a link to the voice message is generated. The email is then transmitted to the recipient electronic address.

Abstract: The method for transferring data sends the data as part of the expanded portion of an expanded permanent identifier which is associated with an end user in a communication system. The expanded permanent identifier is sent along with another permanent identifier, also associated with the end user, during a communication procedure prior to establishing a traffic channel in the communication system. The other permanent identifier includes routing information to a home system forming part of the communication system. Based at least in part on recognizing the other permanent identifier, a home system sends at least the expanded permanent identifier to a destination entity. The destination entity extracts the data from the expanded permanent identifier. In this manner, a traffic channel does not need to be established to transmit the data.

Abstract: The present invention enhances service system selection by a mobile unit in a wireless communication system. The mobile unit determines its geographic position, and based on that position selects the proper service system. The geographic position may be determined using a global position system, dead reckoning, or estimated from a last known position. The distance of varying service systems from the mobile station can then be calculated and a service system selected based on this distance. The mobile station may also use the position information in combination with a database including position information of service systems to select the proper service system. The position information of the service systems can be included in the system selection database. The mobile station may also map service systems based on position information and service availability. The mobile station can then subsequently refer to these maps to estimate available service.

Abstract: A communication system monitors the resources that are available for new users. When the availability of free resources becomes too small or falls below a threshold, the communication system initiates a reduction in the the class of service to selected users. The class of service can be reduced by reducing the quality of service provided to existing communications or by providing selected new users with only lower quality communications. The decision to alter the class of service is alerted to the end user and based on the profile of the end user, appropriate alteration of a specific resource parameter is undertaken.

Abstract: The present invention relates to a handover method in CDMA mobile communication. In particular, a mobile station MS measures a time difference &tgr; between a frame timing in a traffic channel and a frame timing in a perch channel from a second base station BS2. The mobile station transmits the time difference &tgr; to a base station in communication BS1 with the mobile station. The base station BS1 sends the time difference &tgr; and a frame number FN# of the upstream traffic channel to the base station BS2. The base station BS2 corrects the phase of the spreading code for despreading the upstream traffic channel based on the received time difference &tgr; of the frame timing and the notified frame number FN#.

Abstract: In a cellular telephone, a method of reducing background noise of an audio signal resulting from a received signal. Each digital sample of the audio signal is used to calculate an average energy of the audio signal over a number of samples.

Abstract: A calibration function for calibrating a base station can be determined using one or more remote terminals. In one embodiment of the present invention, determining the calibration function includes transmitting a calibration signal, using an array of antenna elements of a first radio, to a second radio, and receiving, at the first radio, a downlink spatial signature related signal from the second radio containing information related to a second radio downlink spatial signature, the information being calculated using the calibration signal. Then, a second radio downlink spatial signature may be determined using the downlink spatial signature related signal. Also, a second radio uplink spatial signature may be determined using an uplink spatial signature signal from the second radio to the first radio. The calibration function may then be determined using the second radio downlink spatial signature and the second radio uplink spatial signature.

Abstract: The base station apparatus compresses one-frame information of a broadcast channel to blocks of ½ of one frame or less and repeatedly sends this block in a one-frame time. The mobile station apparatus decodes the received signal in block units or added block units to carry out error detection. The mobile station apparatus receives and adds up the next block in the case that the error rate exceeds a threshold. The mobile station apparatus repeats this until the error rate falls below the threshold. When the error rate falls below the threshold, the mobile station apparatus stops reception of broadcast channel signals and uses the rest of time until a one-frame time elapses to monitor carrier information of a different mobile communication system for handover.
