Abstract: The availability of one or more resources consumable in operating a mobile terminal and in downloading a file or collection of files to the terminal is reviewed before the file or collection of files is downloaded to the mobile terminal. An estimate is made of the amount of the resource(s) that would be consumed in the download. The download proceeds only if the available resource(s) are sufficient The estimate of the amount of the resource that will be consumed in the download may be based on a prior download of a header of the file(s) to be downloaded. Alternatively, the estimate may be based on the transmission rate of incoming data in combination with one or more of signal strength, bit error rate and the distance between the mobile terminal and a base station from which the file is to be transmitted to the mobile terminal.

Abstract: The invention relates to a signaling method for GSM/GPRS communication systems. The status of a core interface between two core subnetworks is measured in the core network (S2), preferably through a keep-alive mechanism (S1). A status indication message is then sent to the radio network (S3). In this way, the BSS becomes aware of possible interface problems and failures, and can take appropriate actions, such as changing the network operating settings related to the NOM and/or allocated channel types (S4). The invention enables secure operation of NOM-I systems with P-channels irrespective of the Gs interface status.

Abstract: A spreading code determining section (107) determines which spreading code is multiplexed in a received signal that has been received by an antenna (101) and has gone through a radio receiver (102), a correlation processing section (103), a delay profile generator (104), a midamble shift determining section (105), and a path selector (106). When determining that it is during DTX, from the output of the spreading code determining section (107), a DTX determining section (110) reports this to the radio receiver (102), the path selector (106), a JD operation section (108), and a despreading/RAKE-combination section (109) to make them stop processing. Thus, despreading, RAKE combination, and JD demodulation of the received signal are suspended during DTX, so that power consumption can be suppressed.

Abstract: A method and system for managing communication in an emergency communication network is described. The emergency communication network receives a plurality of radio messages from a plurality of channels. The incoming radio messages sometimes overlap in time. Incoming radio messages can be prioritized and played back on the basis of the priority and the time of receipt. In case of overlap of the incoming radio messages in time, the radio message with the highest priority is played first, while the remaining radio messages are stored in a queue. The queue is formed again on the basis of priority. The stored radio messages are played subsequent to the completion of the radio message with the higher priority.

Abstract: An antenna of a wireless interface is installed in a communications suppressing area, and a communications suppressing signal is transmitted. When a wireless telephone device receives this signal, its operation mode set to suppression mode so that when a call is received, an absence notification message is notified automatically. Area information indicating the kind of place the communications suppressing area is provided in the communications suppressing signal, and the absence notification message is generated according to this information. When a call is received during the suppression mode, selection of a response operation is prompted and, if selected, the selected response operation is performed. When a suppression releasing signal is received from an antenna installed in a non-communications suppressing area, or when the duration over which the communications suppressing signal is not received exceeds a preset period, the operation mode is switched from the suppression mode to the communications mode.

Abstract: In a wireless communication system (400), a mobile station (404) or a base station (402), or both working together, determine (302) whether a planned interruption in communications is about to occur; and, in response to determining that the planned interruption is about to occur, progressively increase (306) the round-trip time for a plurality of successive data segments sent before the planned interruption occurs, such that a retransmission timeout value calculated by a sender becomes larger than a time required to complete the planned interruption, thereby preventing a spurious retransmission.

Abstract: A synchronizing method and system between a Radio Frequency (RF) transmitter and a battery powered receiver wherein the transmitter transmits short duration first periodic sync signals which are used by the receiver to maintain proper synchronization of the receiver with the transmitter during second periodic wake-up windows for transmission of data. The receiver wakes for a short duration at the start of each periodic wake up window to receive a possible transmission of data, and if no transmission is received goes back to sleep, and if a transmission is received stays awake to receive the full transmission of data. The basic principle is that the average current consumed by the battery powered receiver in order to wake periodically to receive the first periodic sync signals and the second periodic data transmissions is less than the average current required to maintain the receiver awake continuously. The duration (e.g. 14 ms) and periodicity of (e.g.
