摘要:
A method and apparatus for masquerading the identity of a first communication device returning a missed call placed by a second communication device to a third communication device. The first communication device receives a missed call notification indicating the second communication device placed a first call to the third communication device. Thereafter, the first communication device initiates a second call to the second communication device and directs a network to deliver to the second communication device caller identification information that indicates the second call originates from the third communication device. Moreover, the first communication device may include a missed call log that includes missed call notifications for missed calls placed directly to the first communication device as well as missed call notifications for missed calls originally placed to another communication device. The first communication device can present to a user missed call notifications stored in the missed call log.

In a packet-switched network, a subscribing application subscribes to a network presence server to receive selected network presence information. The network presence server obtains the selected network presence information, at least in part, from status messages that a network access server, such as a packet data serving node (PDSN), sends, for example, to an accounting server. The network presence server then provides the selected network presence information to the subscribing application. The selected network presence information may include an identification of a particular customer that has just initiated or terminated a data session and the network address the particular customer is or was using.

A mobile station that is fully engaged such that it cannot be connected to an incoming call without being disconnected from an existing call receives an incoming call notification. The incoming call notification may, for example, take the form of a short message system (SMS) message or a packet protocol message, such as a session initiation protocol (SIP) message. The incoming call notification may identify the calling party and may explain how to take the incoming call. If the user accepts the incoming call, the mobile station is disconnected from existing calls and connected to the incoming call.

An interface engine that is communicatively connected to a packet-switched network and to a legacy circuit-switched network uses a call processing protocol, such as the session initiation protocol (SIP), for packet-switched network communications and uses a legacy signaling protocol, such as IS-41, for legacy circuit-switched communications. In response to a registration request initiated by a subscriber device on the packet-switched network, the interface engine obtains a service profile for the subscriber from a call processing system, such as a home location register (HLR), of the legacy circuit-switched network. Service parameters derived from the service profile and stored in a service database may be used to apply services on the packet-switched network for the subscriber device.

A flue-gas purification system includes a flue-gas cycling system, a reactor, and an absorbent adding system having at least a catalytic absorbent, wherein the catalytic absorbent is being gasified for reacting with the flue-gas in the reactor in a homogenous gas-gas phase reacting manner. Therefore, the purification system has fast reaction rate between the pollutants of the flue-gas and the catalytic absorbent, which is preferably ammonia, to efficiently remove pollutants, so as to effectively purify the flue-gas.
摘要:
A method and system for dynamically delivering a voice call to a client station depending on whether the client station is currently in a mode in which it can receive data. A switch may receive a request to connect a voice call to a client station that the switch serves, and a determination may responsively be made as to whether the client station is in a mode in which it can receive data communications. If the determination is that it is not in the mode, then the switch may deliver the voice call to the client station by normal routing mechanics. On the other hand, if the determination is that it is in the mode, then the switch may re-direct the call to a circuit/packet gateway that may then extend the call as a voice-over-packet session to the client station.

Locating a lost or misplaced mobile station. A user may dial a designated number, enter the phone number of the misplaced or lost mobile, and the network responsively plays a message to the user informing the user of the geographic location of the cell and sector, typically including city and state information, as well as boundary information of the sector, such as street boundaries. In an alternative embodiment, a user may input the MIN of the lost mobile to a web-based form, and thereby retrieve a map of the cell-sector location of the MS. A service node (SN) is configured to receive a request from a user trying to locate a mobile device. The SN either prompts the user to provide the phone number of the mobile device via an IVRU or through a web-based form sent to a web server connected to the SN. The SN then initiates a call to the mobile device. The standard network processing of such a call includes sending a facilities available (FAVAIL) message to the service control point (SCP). The SCP identifies the call as a request to locate a mobile, and responsively provides location information to the calling SN. The SN in turn provides the location information to the user either by playing a voice message corresponding to the location information or by instructing a web server to provide a map of the location to the user over the world wide web. The method may include an authentication step to ensure that only authorized users are able to obtain location information.

A method and system are disclosed for facilitating location-based services. In an exemplary arrangement, when a mobile station is engaged in a data session with a server, the mobile station may be made to initiate a voice call to a designated number. As a result, a switch or other such entity may send a signaling message (such as an Origination Request message) to a central controller, thereby providing the central controller with an indication of the mobile station's current location. The central controller may then make that location information available to the server. In turn, the server may use the location to perform a location based service, such as providing location-based information to the mobile station.
摘要:
A method and system for controlled provisioning of a desired set of service logic for a subscriber of group of subscribers. In response to a designated stimulus, such as a time-event, a location-event or a threshold-event, a network entity modifies the subscriber profile maintained by a serving system, so as to include in the profile one or more desired parameters. One such modification may be the inclusion in the profile of a trigger that directs the serving system to query a designated network entity for call handling instructions. The designated network entity may then provide a special set of services for the subscriber or group. Further, a mechanism is provided to help ensure that once such a service overlay is imposed, it remains imposed if desired.
摘要:
A private wireless network is able to provide wireless telecommunication services to subscriber mobile stations that also subscribe to a public wireless network. The private wireless network includes a private base transceiver station (BTS), a private mobile switching center (MSC), and a gateway service control point (SCP). The private BTS provides a private network wireless coverage area within which the mobile station can communicate with the base transceiver station over an air interface. The gateway SCP has a private network database containing private network data records for subscribing mobile stations. A private network data record includes a private network service profile and a private network locator address. The public wireless network has a home location register (HLR) with a public network database containing public network data records for subscribing mobile stations. A public network data record includes a public network service profile and a public network locator address. When a subscriber mobile station is active on the private wireless network, the private network locator address identifies the private MSC, and the public network locator address identifies the gateway SCP. By providing the private network wireless coverage area so that it overlaps the public network's wireless coverage area, the subscriber mobile station may be handed off between the private and public wireless networks.
