Abstract: A network communication system is provided for communication between network nodes, including individual nodes and a central control station node. In the network, signals are transmitted from the central control node to identify specific timeslots in which individual nodes may transmit a request signal to the central control node. When a first individual node then has data to transmit, the first individual node transmits a request signal to the central control node in its identified timeslot requesting allocation of time for transmitting a specified amount of data. In response to the request signal, the central control node transmits a grant signal specifying at least one timeslot allocated to the node for transmit its data to the central control node. The first individual node then in response to the grant signal, transmits its data over the specific timeslots.

Abstract: A communication device and a method for controlling a communication device that can load or unload service information at appropriate timings by flexibly designating discriminating conditions of connection or disconnection of a link. A service manager reads out necessary service information, such as service program or driver software, from the information memory area based on discriminating conditions designated in communication controlling information of the communication status. The service manager loads service information to a temporary information memory area in a host device. The service manager also unloads unnecessary service information from the temporary information memory area in the host device. A connection manager then performs communication protocol for communicating between the service information loaded in the temporary information memory area of the host and the service information memory of the device side.

Abstract: A wireless network has nodes, which can be accessed by wireless terminals via wireless access links, coupled via wireless transit links using multiple directional antenna beams. The nodes are self-organizing and self-adapting as nodes are added and as other changes occur. A new node uses beam scanning to listen for signals from any existing nodes and responds accordingly to join a network. Established nodes each recurrently transmit a welcome message on unused beams, to be received by a new node. Failure of transit links, e.g. due to interference on a channel frequency, is detected with automatic restoration using another frequency. Beam scanning can be enhanced using alternate overlapping beams and diversity techniques.

Abstract: A method for characterizing base station processing and memory capabilities in a wireless communications system enables resource allocation to take these capabilities into account and to make allocations that avoid base station overload. A method for allocating resources in a wireless communication system including a base station and a radio network controller (RNC) begins by receiving an allocation request for a new service at the RNC. A set of resources is selected by the RNC to allocate to the new service, taking into account the capabilities of the base station. The allocation request is executed by the RNC if a set of resources can be found that does not exceed the capabilities of the base station.

Abstract: A weight vector of a precedent frame calculated by a weight vector calculator (4) and stored in a memory (3) is applied to a signal received through a plurality of antennas (ANT1, . . . ANTn) for removing an interference wave component. A synchronous position is detected from the signal subjected to removal of the interference wave component by a method of correlation synchronization, and supplied to the weight vector calculator (4). The weight vector calculator (4) executes calculation of a weight vector with the detected synchronous position as a start position. Thus, when signals of the same frequency are received in a CS in an overlapping manner, the synchronous position of a signal received from a desired PS can be correctly specified.

Mobile stations transmit particular reconnection attempt status information to the wireless infrastructure. The reconnection attempt status information, along with the aggregate statistics of other mobile stations, is used by the infrastructure to adapt access parameters to increase or decrease the likelihood of successful access. This allows the infrastructure to tune access parameters to particular mobile station information and it also allows the infrastructure to provide better resource management for both traffic channel assignments and access channel usage.

Abstract: The present invention is a system for distributing the reconnection attempts of multiple system users in a CDMA telephone system over a broad time window. The present invention allows either the base station or the mobile station to process data to determine an appropriate reconnect time. The data may include resource capability, priority, client connects pending, and timing and amount of data on pending connection requests. Using this data information, a more efficient reconnection scheme may be developed. The number of requests required to successfully connect can be reduced while increasing the utilization of resources and reducing the delay until connection. Under an intelligent reconnection scheme, the probability of system users attempting simultaneous reconnection is reduced, thus reducing the likelihood of reconnection collision.

Abstract: The present invention is a method and system for buffering and replaying a segment of a voice or data transmission. A connection is established between two end nodes in the network. At an intermediate node in the network between the end nodes, a predetermined segment of the data is maintained in a memory as a buffer. Upon receiving a request from one of the end nodes to replay the segment, that segment is replayed and transmitted to the requesting node. The request may be made by a user at one of the end nodes, or may be made automatically after detecting corrupt data. Because the buffering module is in the network, it need not be incorporated in premises or mobile equipment. Because the buffering module is remote from the requesting end node, the replayed data does not contain errors introduced in the original data between the buffering module and the requesting end node.

Abstract: The present invention implements a method and system for dynamically adapting the modulation and coding scheme for radio links in a wireless communications network based on a retransmission environment model in order to maximize throughput and most efficiently allocate bandwidth resources. The present invention encompasses a refined calculus and methodology for deriving the link adaptation thresholds in a retransmission environment using a complex model and analysis of the retransmission environment. The present invention holds particular application for wireless data communications as opposed to real time data services because it is based on a retransmission model applicable primarily for data services. A critical component of this new link adaptation system is a “no transmission” cutoff mode that is selected for SIR below a base threshold value. This new mode prevents system instability and misallocation of bandwidth in a wireless communication system.

Abstract: The present invention is a system for distributing the reconnection attempts of multiple system users in a CDMA telephone system over a broad time window. The invention assigns a randomly initial wait time for each system user from a time window. After the initial wait time is assigned to a system user, any unsuccessful reconnection attempt by that user results in quadrupling the current wait time, until a maximum wait time window is reached. Once the maximum time window is reached, the system user continues to attempt reconnection every cycle of the maximum wait time until connection is maintained. By randomly assigning an initial wait time to each system user, the probability of system users attempting simultaneous reconnection is reduced, thus reducing the likelihood of reconnection collision.

Abstract: A mobile terminal communication system is disclosed wherein, when communication interruption occurs, communication is re-started automatically without labor by a user to perform a call re-origination operation. If communication is interrupted by deterioration of a radio circuit condition between a fixed terminal and a mobile terminal, then an automatic call origination control section automatically originates a call to the fixed terminal and the mobile terminal based on subscriber number information stored in a subscriber number storage section of an exchange and information of a radio service area; in which the mobile terminal is present, stored in a position information database section. If a response is received from both of the fixed terminal and the mobile terminal, then communication is re-started.

Abstract: A radio base station, when detecting a collision of reception signals, transmits an access-restricted transmission allow signal IDLE2 to a irrelevant-to-collision radio terminal PS3 for access restriction. A plurality of relevant-to-collision radio terminals PS1 and PS2, when receiving the access-restricted transmission allow signal, set transmission delay times TR1 and TR2 determined by random numbers, respectively, and when receiving the access-restricted transmission allow signal after the lapse of their respective delay times, start the same transmission operation as when receiving a normal transmission allow signal. A separate radio terminal PS3, when receiving the access-restricted transmission allow signal before intended new signal transmission, suspends the new signal transmission until receiving the normal transmission allow signal.

Abstract: A method and system for reserving a communication channel in a mobile telecommunication network. After a mobile station's initial attempt to place a call fails, because of congestion in a first network, for example, the mobile station requests reservation of a communication channel. Preferably, the reservation request is transmitted via a second network, different from the network used for the initial call attempt. In response to the request, an identification of the mobile station is placed in a queue of the first network for access to a communication channel. Once a communication channel becomes available in the first network, that channel is reserved for use by the mobile station.

Abstract: Apparatus and a method for establishing a cellular mobile call. If no radio traffic (voice or data) channels are available for a calling or called mobile station (MS), then a test is made to determine the expected wait time before a channel becomes available. If the expected wait time is less than a first threshold, then the call or the call request is queued. If a channel for an incoming call to an MS does not become available before a second time threshold, then the caller is notified by an announcement that the call has been queued and is expected to be established in a short time. If the caller of an incoming call to the MS does not disconnect, then the MSC waits for an available channel and establishes a connection to the MS over that available channel. For an outgoing call from an MS, a control message is sent to the MS to trigger an indication of the queued status to the user. The indication may be one or more tones, a data display, or the playing of a pre-recorded announcement.

Abstract: In a transmission/reception system, adaptive arrays separate signals from users by multiplying radio wave signals received through array antennas by reception signal weight vectors. A reception signal coefficient vector calculator preliminary calculates a reception signal vector of a U wave and produces a table in a memory. If a cross correlation value of the reception signal vector of the U wave and the reception signal vector of a user newly requesting connection is smaller than a prescribed value, a channel can be allocated to the newly requesting user even if the U wave level per se is high.

Abstract: A mobile station is configured to measure receiving qualities of respective signals from a first antenna and a second antenna of a base station (S3, S5), store the results of the measurement, and request the base station to retransmit a signal from an antenna with a higher receiving quality, based on the stored measurement results, when an error is detected in received data thereafter (S10, S11, S12). The base station retransmits the data, using the antenna with the higher receiving quality (i.e., a base station antenna to yield the higher receiving quality at the mobile station) (S15). In another aspect, the mobile station measures a receiving quality of a signal and notifies the base station of the receiving quality. The base station selects a radio channel adapted to a receiving quality on the basis of the measurement result and transmits a signal, using the radio channel.

Abstract: The present invention is directed to a system and method that allows mobile platforms each supporting any of a variety of call types, and each having differing mobility characteristics, to maintain connectivity to a backbone network in spite of unreliable radio links that occasionally fail. It accomplishes this by using automatic and user-transparent reconnection attempts for appropriate call sessions when an interruption of the link occurs. The network may be supporting a variety of different call types simultaneously. Access to network connectivity resources can be provided according to call session priority based on (for example, call session type, platform mobility, hand-off status, and user class (fee-for-service)) criteria. The technology allows support of suspended sessions and uses repeated reconnection attempts with priority access to network resources. It also provides for hand-offs of suspended sessions to neighboring gateways as mobile terminals move throughout the service area.

Abstract: A method for a mobile station and a base station to which the mobile is being handed over, and corresponding apparatuses for use by the mobile and the base station. The method for use by the mobile station is for determining whether dynamic configurations are in use by the base station to which the mobile is being handed over, and the method for use by the base station is for determining whether to use a dynamic configuration (if the base station uses dynamic configurations) or to switch to a static preconfiguration in communicating with the mobile. The base station to which the mobile is being handed over is of one wireless communication system (such as the UTRA wireless communication system) and the base station doing the handing over is of another type (such as GSM). Both base stations are assumed to broadcast control signals on a respective broadcast control channel.

In one aspect of the invention, the method comprises the steps of receiving a directed retry message on a mobile station; setting SCANINTERVAL to zero and HL_FREQ to high if an up-to-date neighbor list does not exist on the mobile station; completing at least one neighbor list measurement within a wait time period; and invoking RTC-4. The step of completing the least one neighbor list measurement is accomplished within a wait time of about four seconds. The step of completing the least one neighbor list measurement preferably comprises completing 2 neighbor list measurements. If the wait time exceeds about four seconds the mobile station reverts to camping or idle condition.

Abstract: A wireless communication system wherein wireless infrastructure adapts access parameters and manages channel resources based on detailed reconnection information obtained from individual mobile stations. Mobile stations transmit particular reconnection attempt status information to the wireless infrastructure.

Abstract: Disclosed is a method for utilizing SCH resources more efficiently for supplemental channels (SCH) by minimizing gaps between data bursts due to overhead delays. Such gaps are minimized using a supplemental channel sharing algorithm to prospectively assign SCH resources supporting existing SCHs and to schedule future issuance of DNRs such that currently unavailable SCH resources may be prospectively assigned based on states of the SCH resources, wherein an existing SCH is a SCH over which a data burst is currently being transmitted.

Abstract: A system and method of reducing control message signaling load in a radio telecommunications network. When an authentication request is issued by the mobile switching center (MSC), the home network performs authentication of the visiting subscriber. When authentication fails the home network determines if a threshold value is reached. If so, a suitable authentication code portion is included in the return message so that local authentication of the visiting subscriber may be performed. The MSC is able to locally authenticate a visiting subscriber trying to access the network thereby suppressing the transmission of additional authentication requests and failure reports to the home network. For failed authentications, the VLR transmits authentication failure reports to the home network. If a threshold value is reached the MSC locally authenticates the mobile subscriber's subsequent attempts so that the VLR is precluded from sending additional authentication failure reports to the home network.
