APPLICATION NOTIFICATION AND SERVICE SELECTION USING IN-BAND SIGNALS |
摘要 |
In-band signaling may be used between two stations to determine the capabilities of the stations and/or send actionable information between the stations participating in the call. The in-band signals are indicative that the station that is transmitting the in-band signals can use in-band signals as a conduit to send and/or receive various types of information and are used to probe whether the receiving station can operate similarly. If the receiving station detects and reacts to the in-band signals, then both stations can pass control information and data as well as enhancements between each other, without any need of infrastructure upgrade and/or quality compromise to legacy phone users. Additionally or alternatively, out of band interfaces and watermarking may also be used.
