Abstract: A system and method for preparing and sending e-mail communications using a wireless communications device are disclosed. In one embodiment, input data comprising audio, image, and/or video data is encoded and transmitted to a cellular network. An integrated e-mail processor connected to the cellular network processes the coded data into a composite e-mail message and forwards the message to a server. The server then forwards the composite e-mail message to the indicated recipient(s). In another embodiment, the wireless communications device processes the coded data into a composite e-mail message and forwards it to a server via a cellular network. In either embodiment, the server may be dedicated to the cellular network. The invention thus enables users of handheld wireless communications devices, users of other devices lacking typing keyboards, or users presently unable to use a typing keyboard to prepare and send e-mail messages.

Abstract: A non-linear distortion compensation circuit, a transmission equipment employing the same and a mobile transmission equipment may accurately compensate distortion caused by non-linearity of a transmitter per bit (symbol) even while the base station is performing transmission power control for the transmitter of the mobile station.

The non-linear compensation circuit has compensation component generating means for generating a compensation component for a non-linear distortion depending upon a transmission power per bit of the digital signal and the transmission power control information, and compensating means for compensating the non-linear distortion of the transmission signal by the compensation component.

Abstract: A repeating apparatus of the present invention converts a data signal from the mobile switching center to an intermediate frequency signal and transfers the intermediate frequency signal to an unused telephone line and a dedicated line network. The apparatus converts the intermediate frequency signal transferred through the unused telephone line and the dedicated line network to the data signal frequency signal and transfers the data signal to the mobile switching center. In the present invention, the intermediate frequency signal is transferred between a mother station and at least one first child station through the unused telephone line and the intermediate frequency signal is modulated to transfer between the mother station and at least one second child station through the dedicated line network.

Abstract: A radio communication system has means for improving power control of a communication channel for the transmission of data after an interruption in the transmission. This is done by applying power control in steps of variable size at the start of a transmission, using a large step size initially which is reduced as the power approaches a target value. In one embodiment the step size is reduced when the sign of a power control command reverses, while in another embodiment the step size is reduced after a predetermined time. These techniques reduce the time taken for power control to be established, thereby addressing the problem that data transmissions at the start of a data channel are likely to be corrupted if the power level is too low, or to generate extra interference if the power level is too high.

Abstract: In a mobile communication system, a central control unit assigns pairs of upstream and downstream channels to mobile station units located in a radio zone of a base station unit to carry out a two-way communication between the mobile station units, and the central control unit assigns pairs of upstream and downstream channels to the mobile station units to carry out a one-to-multiple group communication between the mobile station units. A memory unit stores vacant channel data indicative of the presence of a vacant channel with respect to the group communication carried out by the channel assignment of the central control unit. A broadcast message unit transmits a broadcast message containing the vacant channel data, stored in the memory unit, to each of the mobile station units. A message receiving unit receives the broadcast message transmitted by the broadcast message unit.

Abstract: A system that provides a wireless broadband connection between base stations and customer sites is described. The system includes indoor units within the base stations and customer sites and communicate across cables to outdoor units. The indoor units link to routers, switches and other devices and services. The outdoor units transmit and receive wireless data and send it to the indoor units. The indoor units control the timing of detector measurements in the outdoor unit by transmitting a regular, repeating control message at a predetermined time. Once the outdoor unit receives the control message, it samples its detectors and reports measurements back to the indoor unit.

Abstract: The present invention relates to a base station (1, 10, 20) and a mobile terminal (40, 50, 60) as well as a communication method for communicating in a wireless radio communication system. Thereby, the information is transmitted and received in medium access control frames of the communication system, whereby the transmission power of at least a broadcast control channel and a frame control channel in a respective medium access control frame transmitted by a base station is increased after certain time intervals to an increased transmission power level as compared to the transmission power level of other medium access control frames transmitted during said time intervals.

Abstract: A technique is disclosed for automatically determining system configuration information, including the type and version of hardware installed on remote equipment. A modified central control station communicates with each remote cell station to perform an iterative system configuration process that progressively refines the system configuration information, until the actual installed system configuration is obtained, or until manual intervention is required. The system configuration process initially assumes a system configuration having the cell station fully installed with a default hardware component. The default “guess” is sent to the cell station which, in turn, communicates with each of the hardware components using a message protocol appropriate for the assumed configuration. In one embodiment, the cell station queries each of the hardware components for their associated type and version.

Abstract: An method of establishing a radio bearer (RB) resource in an RAN to support communication with a mobile terminal uses a radio bearer resource request message to expedite RB resource allocation. The mobile terminal transmits a packet channel access request message that uniquely identifies the access request type as a RB access request. The requested RB may be a signaling radio bearer (SRB), in which case the RB access request message may identify the specific type of SRB desired. More generally, the RB access request message identifies the access request type as a RB resource request, which is enough to alert the RAN that RB resources are required. The RAN then sends an uplink packet channel assignment and the mobile terminal specifies the RB resource details by transmitting RLC header information on the assigned uplink channel.

Abstract: An envelope calculation section (113) calculates the amplitude of a transmission signal after the multiplexing thereof. When the calculated amplitude is beyond a permissible amplitude value, a correction coefficient calculation section (114) calculates a correction coefficient that is the difference between amplitude values before and after a correction. Multiplication sections (115) and (116) calculate a correction value by multiplying a filter coefficient by a correction coefficient. Subtraction sections (119) and (120) subtract the correction value from the transmission signal after a filtering operation. Thereby, the transmission amplitude at the time of a peak can be suppressed without increasing the number of filter operation circuits.

A delivery mode type determiner determines the service delivery mode associated with the data service. If the service delivery mode is a background delivery mode, the data service is effectuated with the intended receiving station instead of being redirected pursuant to a call forwarding, or other service interaction indicia, feature.
