摘要:
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 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.

A carrier providing wireless services provides ringback media such as call tones via one or more call tones content providers. In one aspect, a service entity (e.g., SCP or application server) is provisioned with data unique to ringback media service subscribed to by the subscriber. The service entity provides routing instructions to a mobile switching center identifying a ringback media server (e.g., content provider platform) to render ringback media to the caller. In another aspect, a caller can exercise control over the play of ringback media, e.g., by inputting DTMF tones, which responsively cause a ringback media server to change the play of ringback media, e.g., stop it or play a different selection. In another aspect, when a subscriber initiates a call to called party that subscribes to a competitor carrier, the carrier limits exposure of the subscriber to the ringback media of the competitor carrier. In one possible configuration, the carrier inserts its own ringback media.

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.

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.

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.

A media system includes a content platform that provides an interface for browsing and/or purchase of ringback media content by a user of a communications device. The system includes a profiles database containing profile information for a multitude of users of communications devices. The media system further includes a memory storing instructions for execution by the platform which causes it to 1) obtain information from the device including assignment of ringback media content to contacts in an address book maintained on the device; and 2) update the profiles database in accordance with the information obtained from the device. The information obtained in 1) may be obtained automatically, each time the user accesses the content platform. The system may further include an analyzer module which is used to generate targeted promotional messages based on the contents of the profile database.

Disclosed are methods and systems for providing pre-call-connection messaging services to calling parties. In at least one embodiment, a first call-setup request is received from a calling party, reflecting a request that an active call be set up between the calling party and a called party. Responsive to the first call-setup request, at least one network device starts to attempt to establish the active call between the calling and called parties at least in part by transmitting a second call-setup request to the called party. Prior to receiving a response to the second call-setup request, the at least one network device starts to record a message for the called party while continuing to attempt to establish the call. If the active call is not successfully established prior to an affirmative termination of the message recording, the recorded message is thereafter made accessible to the called party.
