Methods and systems for facilitating distribution of ringback files to caller devices are provided. A ringback file server may receive a request to associate a ringback file with a callee device and a caller device. Responsively, the ringback file server transmits a copy of the ringback file to the caller device, thus enabling the caller device to play out the ringback file when the caller device subsequently initiates a call to the callee device. Preferably, the ringback file is a high quality audio or video file. Thus, locally storing the ringback file at the caller device facilitates playout of high quality ringback media and also avoids requiring that the ringback file server stream ringback media in-band to the caller device.

A system and method for carrying out a dynamic-routing service is provided. The system includes a service control point (“SCP”) that is operable to provide routing instructions for the plurality of subscriber terminals. And each of the plurality of subscriber terminals has a subscriber address and an associated call history. In carrying out a dynamic-routing service, the SCP receives a request for routing instructions for terminating a voice call to a call-subscriber address of the plurality of subscriber addresses. Responsively, the SCP selects from the plurality of subscriber addresses a delivery address for terminating the voice call to based on the call histories associated with the plurality of subscriber addresses. After selecting the delivery address, the SCP develops routing instructions for terminating the voice call to the delivery address, and then provides the routing instructions for terminating the voice call to the delivery address.

A flue-gas purification system includes a flue-gas cycling system, a reacting means, 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 reacting means 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.

After a call with a called party ends, a caller is provided with prompts or messages which allow the caller to control ringback media content which is to be rendered when the caller calls the called party in the future. For example, the caller is provided with prompts by which they can select ringback content from content they already have purchased and apply it to the called party number. Alternatively, the caller is linked to a content provider where they can purchase additional content and have it applied to the called party number. Thus, the caller is able to exert control over ringback media.

Methods and systems are disclosed for integrating a plurality of providers of media content such as call tones, games, ringers, etc. with a wireless service provider network. The wireless service provider network includes a media service platform, a profile database and a media database. The media content providers provide an interactive facility, e.g., Web interface, allowing a user to purchase content. A notification message is sent to the user which is triggered in response to purchase of content. The notification message includes a network address (e.g., URL) of the media service platform. The media service platform checks to see if the purchased content is stored in the media database, and if not, it pulls it over from the content provider. The profile database is updated regarding the purchased content in response to information from the user.
摘要:
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.
