Abstract
Apparatus, and associated method, converts real-time multimedia information generated pursuant to an RTP protocol into a form amenable for transmission upon a radio channel, such as a radio channel defined in a cellular communication system. When converted, the informational content of the multimedia information is transmitted in a manner that achieves spectral efficiency and low, constant delay. Once transmitted over the radio channel, the multimedia information is converted back into form corresponding to the RTP protocol before being sent to the receiving station.
Claims11
Apparatus for a radio communication system having a wireless gateway, the radio communication system operable to communicate multimedia information with a first multimedia device and a second multimedia device, for providing the multimedia information transmitted by the first multimedia device upon a special channel in radio-link format to the second multimedia device, said apparatus comprising:
- a real-time media source at which the multimedia information is sourced;
- a requester coupled to said real-time media source to receive indications of when the multimedia information is to be communicated by the first multimedia device, said requester for requesting allocation of the special channel upon which to communicate the real-time media;
- a control plane information generator coupled to receive indications of the multimedia information, said control plane information generator for generating control plane information, the control plane information controlling a manner by which to provide the multimedia information, once converted into packet-data form, to the second multimedia device;
- and
- a format converter coupled to receive indications of the multimedia information in the radio-link format, said format converter for converting the multimedia information into the packet-data form, the multimedia information, once converted into the packet-data form provided to the second multimedia device in the manner determined by the control plane information.
Apparatus for a radio communication system having a wireless gateway, the radio communication system operable to communicate multimedia information between a first multimedia device and a second multimedia device, for providing the multimedia information transmitted by the first multimedia device upon a special channel in radio-link format to the second multimedia device, said wireless gateway comprising:
- a real-time media source at which the multimedia information is sourced;
- a requester coupled to said real-time media source to receive indications of when the multimedia information is to be communicated by the first multimedia device, said requester for requesting with said control plane information generator allocation of the special channel upon which to communicate the real-time media;
- a control plane information generator coupled to receive indications of the multimedia information, said control plane information generator for generating control plane information, the control plane information controlling a manner by which to provide the multimedia information, once converted into packet data form, to the second multimedia device;
- and
- a format converter coupled to receive indications of the multimedia information in the radio-link format, said format converter for converting the multimedia information into the packet-data form, the multimedia information, once converted into the packet-data form provided to the second multimedia device in the manner determined by the control plane information.
