Abstract
A modular suite of peer-to-peer protocols that are independent of communications network architecture supported, and the type of switching systems (packet-switched or circuit-switched), is used for a broadband and/or narrowband communications network. The protocols are comprised of client-server-oriented signaling messages that are restricted to include information and parameters associated with only one particular function of traditional call processing.
Claims9
A method of communicating signaling messages for use in broadband and narrowband communications networks, said method comprising the steps of:
- recognizing a plurality of operations associated with call processing functions to be performed in order for said networks to deliver communications services to one or more users:
- performing said call processing functions in a plurality of servers wherein each one of said servers executes a group of said operations that are substantially related to each other so as to limit communications between said servers in the performance of said call processing functions;
- and
- exchanging signaling messages between said servers for performing said call processing functions, said signaling messages being indicative of a) particular one or more operations to be performed within at least one of said servers, and b) performance attributes of said one or more operations to be performed.
A system for exchanging signaling messages between entities of narrowband and broadband communications networks, said system comprising
- means for recognizing operations associated with call processing functions to be performed for delivery of communications services to users by said networks;
- means for performing said call processing functions in at least three servers, wherein each one of said servers executes a group of said operations that are substantially related to each other so as to limit signaling communications between said servers, and wherein said servers include a first server for call control functions, a second server for channel control functions, and a third server for connection control functions;
- and
- means for exchanging signaling messages between said servers to perform said call processing functions, said signaling messages being indicative of a) particular one or more operations to be performed within one of said servers, and b) performance attributes of said one or more operations to be performed.
