A system and method for interactively selecting call treatment in real time for an incoming call in a radio telecommunications network. A modified mobile station includes a display, a browser application that presents call information regarding the incoming call and call-treatment options on a pop-up menu the display, a keypad for a user to select a call-treatment option, and a Client Access Function Teleservice (CATS) handler that packages the selected call-treatment option in an IS-136 R-DATA message and sends the R-DATA message to a modified mobile switching center (MSC). The MSC determines that the R-DATA message is a CATS message from the value of the Higher Layer Protocol Identifier (HLPI) in the R-DATA message, and sends the call-treatment option to a modified service node in a short message service (SMS) message. A server in the service node receives the SMS message from the MSC, extracts the selected call-treatment option, and translates the call-treatment option into service scripts understood by the service node.

A method and an access domain node identify and manage a type of service offered by a service provider to user domains. A service template is prepared by the service provider, comprising an address of a server and a protocol identifier, as well as policies for controlling traffic for the service.

A system and method in a local area network based on the Universal-Plug-and-Play (UPnP™) technology represents an infrared (IR) remote control (RC) pass-through protocol in the Content Directory Service (CDS) of a media server that transmits an audio-video (AV) media stream over the network to a media renderer. The CDS includes a listing of media content items that represent media source devices that provide media content to the media server, and a listing of associated IR pass-through protocol identifiers (IRPT-IDs) for each media content item. Each IRPT-ID identifies an IR pass-through encoding / decoding protocol usable by the IR decoder in the media server and each IRPT-ID has an associated internet protocol (IP) connection point (IRPT-CP). The media renderer browses the CDS to identify the media content item and its associated IRPT-ID / IRPT-CP pair. The IR RC at the media renderer sends RC commands to the media renderer that are encoded using the IR pass-through protocol represented by the IRPT-ID. The encoded RC commands are transmitted over the network in the reverse direction of the AV media stream back to the media server, where they are decoded using the same IR pass-through protocol and then IR transmitted via IR to the media source device to control its operation.
