Abstract: The present invention provides a method and apparatus for regulating the transmission power of a transmitter generating a CDMA signal. The CDMA signal is transported over a main channel which includes a plurality of sub-channels, each sub-channel associated with a particular sub-signal of the CDMA signal. The apparatus includes primarily an SNR estimator functional bloc and a logical functional bloc. The SNR estimator functional block receives as input the sub-signals and is responsible for commuting an estimate of the ratio of the total signal energy in the sub-signals to the total noise energy in the sub-signals. The logical functional bloc generates a control signal in dependence of the SNR estimation computed by the SNR estimation functional bloc. This control signal is sent back to the transmitter generating the CDMA signal, and is indicative of either a power-up or power-down command for regulating the transmission power of the transmitter.

The requested number and/or speed dial number are converted from text to speech and the public telephone switch automatically dials the requested number.

Abstract: A mobile station in a cellular telecommunication network includes an apparatus and method for storing a calling party identification signal. This calling party identification signal is transmitted to an originating MSC along with the call set up signals. The originating MSC then transmits the calling party identification signals to an HLR which transmits them to a serving MSC for delivering to the called party mobile station. Accordingly, the method and apparatus support the delivery of calling party identification signals to the called party without requiring the creation and maintenance of databases for storing such information. The mobile station as well as the MSCs adaptive to store the calling party information signals and to receive and transmit the same. The communication signal definitions between the mobile stations MSCs base stations HLRs and VLRs are all adapted to include and support the transmission of the calling party identification signals which are permanently stored in the mobile station.

Abstract: A mobile station communicates with an RSVP-aware network over an air interface standard that has a wireless quality of service standard. The mobile station transmits an RSVP message to an end terminal through the network's RSVP-enabled routers. The end terminal transmits an RESV response message back to the mobile station. A base station controller intercepts this message and sets up the wireless resources if possible.

Abstract: A wireless communication system constructed according to the present invention includes an originating mobile switching center (MSC), a home location register (HLR), a serving MSC and supporting infrastructure for each MSC. Such supporting infrastructure includes a plurality of base station controllers (BSC) and a plurality of base stations. The base stations support wireless communications within respective cells to service mobile units operating in the cells. When a call is received by the originating MSC intended for the mobile unit, the originating MSC determines whether the call originated from a private branch exchange. Such determination is made based upon whether the call was incoming on a designated trunk line or from a caller ID assigned to the private branch exchange. If the call originated from the private branch exchange, the call is competed and a distinctive ringing is provided to the mobile unit to indicate that the call originated at the private branch exchange.

Abstract: A wireless communication system and a mobile station employ at least one threshold to evaluate the quality of transmissions from a serving base station to determine when the mobile station enters a Dead Zone adjacent a border cell of the system. Such thresholds not only consider the ratio of carrier energy (Ec) to interference (Ec/Io) but also consider the energy of the carrier itself. When the relevant measured (or calculated) carrier energy Ec and/or carrier energy to interference ratio Ec/Io are passed, the mobile station performs system reselection, attempting to acquire a different system/carrier. The thresholds employed may be passed from the base station to the mobile station in the System Parameters message, for example.

Abstract: An application module, that is part of an electronic assembly including a controller module, is coupled to a backplane bus structure. The backplane comprises a differential bus(s) having a TX and RX data signal, a differential clock signal, and a single ended collision detection line. The application module comprises differential bus transceivers that are controlled by differential bus control logic on the application module. The control logic compares data bits received over a collision detection line with the data bits the application module originally transmitted. If the data is not the same, a collision has occurred and the control logic places the bus transceivers into a high impedance state. A data packet controller on the application module can only detect certain types of collisions that occur in the single ended environment. The control logic enables the data packet controller to recognize a collision that it normally would not.

Abstract: A method and apparatus for controlling multi-party conference calls includes circuitry which is operable according to a new conference call protocol. The protocol and accompanying apparatus and method allow a conference call controlling party to selectively have private conversations with one of the subject parties in the conference call. Additionally, the controlling conference call party may selectively drop conference call participants. A mobile station includes a store for storing the conference call participant “subject party setup number” in relation to the subject party number and/or name. The mobile station also allows the conference call controller to scroll up and down a list of conference call participants. This allows the controller to be certain of a conference call participant's “call set-up number” when using a command for a private call or a command to drop a conference call participant.

Abstract: In a packet switching network, a distributed architecture provides efficient computation of routes in Quality of Service (QoS)-based routing scenarios. Using a client-server model, only designated route servers store and maintain a database containing the entire network topology, so that each network node is not required to store and maintain the network topology. Client nodes maintain a cache containing pre-computed routes so that they can often make routing decisions autonomously. A client contacts a designated route server only when the client cannot obtain from its local cache a route to a given destination that meets the performance requirements. A client cache may contain pre-computed routes with designated QoS profiles to all destinations or to a subset of destinations. Route servers may also contain caches, which may contain pre-computed routes to all destinations in the network with all QoS profiles, or may contain only a subset of such routes.

Abstract: An apparatus and method for limiting unauthorized access to a multicast by one or more members of a subnet reconfigures the multicast if all subnet members participating in the multicast do not reply to a query message. To that end, the apparatus first receives a query message requesting the identity of all subnet members that are participating in the multicast. Upon receipt, the query message is forwarded to each subnet member that is participating in the multicast. Receipt of the message by selected subnet members participating in the multicast causes a reply message to be forwarded. It then is determined if a reply message has been forwarded by all subnet members participating in the multicast.

Abstract: A mobile communications system includes a plurality of cell segments each allocated primary carriers to carry circuit-switched traffic and packet data carriers for carrying packet-switched traffic. The packet data carriers include two sets of carriers, a main set of carriers and a secondary set of carriers. The main packet data carriers are allocated to corresponding cell segments. The secondary carriers are allocated to high capacity segments, which may be segments having high bursty traffic or segments in which a hierarchical cell structure is implemented. For high bursty cell segments, the main carriers are used to carry control signaling for performing selection or reselection. However, in such high bursty cell segments, the secondary carriers are not used for performing cell segment selection or reselection.
