The system uses a digital network to propagate the information between switches in a dynamic message format.
The present application claims priority to provisional patent application Ser. No. 60/575,207 entitled �Multi PBX Telephony Event Notification for SIP Framework,� filed on May 27, 2004, which is incorporated in its entirety by reference.
FIELD OF THE INVENTION The present invention is in the field of telephony communications, including call processing and switching equipment, and pertains particularly to methods and apparatus for synchronizing call states between multiple call-handling points in a communications network and to providing event notification to session participants.
BACKGROUND OF THE INVENTION Telephone call processing and switching systems are, at the time of the present patent application, relatively sophisticated, computerized systems, and development and introduction of new systems continues. Much information on the nature of such hardware and software is available in a number of publications accessible to the present inventors and to those with skill in the art in general. For this reason, much minute detail of known systems is not reproduced here. One document which provides considerable information on intelligent networks is �ITU-T Recommendation Q.1219, Intelligent Network User's Guide for Capability Set 1� dated April, 1994. This document is incorporated herein by reference.
SUMMARY OF THE INVENTION A system for synchronizing party information and call-state information between two or more telephone switches involved in establishing a multiparty communication session is provided, including at least one server application for serving information and receiving information; and a translation service for translating received information between formats of telephony and those of digital messaging.
BRIEF DESCRIPTION OF THE DRAWING FIGURES FIG. 1 is an architectural overview of a communications network wherein call-state synchronization is practiced according to an embodiment of the present invention.
DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an architectural overview of a communications network 100 wherein call-state synchronization is practiced according to an embodiment of the present invention. Communications network 100 includes a telephone network 101, which in this example is a public-switched-telephone-network (PSTN), and a data-packet-network (DPN) 102. Network 101 may be a private telephone network instead of a public network without departing from the spirit and scope of the present invention.
A calling party's equipment 103 is illustrated in this example having connection to network 101 at the initial point of PBX 112. In this example this point will be referred to as the �calling party�. Calling party 103 is logically illustrated herein as a communications station, which may be represented by a telephone (106) and a data terminal (107). Party 103 is logically illustrated with a communication network connection to PBX 112 within PSTN 101.
A PC 110 and a telephone 111 represent a third party 105 in this example. Party 105 is not, in this example a calling party, but is a party that is added to a two-party call between party 103 and party 104 to make a three-party call in this example. Party 105 has connection to switch 113 via a network communications line 116. In this example a single PBX (113) maintains call representation state on parties 104 and 105. PBX 112 maintains call representation state on only party 103. Assuming party 103 initiates a two-party call to party 104 through switches 112 and 113, the states of both parties are maintained both at switch 112 and at switch 113 because of the fact that only one call is active. In other words, a simple two-party connection is, without benefit of the present invention, already state-synchronized in that both switches �know� of all of the call events occurring during the two-party session for both parties.
In one embodiment voice messaging may be used to alert parties engaging in a session that some call state has occurred with reference to another party of the session. For example, a message such as �party 2 has placed party 3 on hold�. In this case, the notified party also may be given voice-synthesized identity information of the parties involved in the �hold� call-state event. Identification of the parties pursuant to the event may also be caused to display on a suitable display window of a telephone or other computerized device.
PBX switches 205�207 have connection to each other via telephony trunking 211. Each PBX switch illustrated within network 201 is CTI-enhanced by a CTI-processor running an instance of transaction server (T-Server) known to the inventor, which is proprietary CTI-enhancement software. T-Server instances are installed on processors 208, 209, and 210, all connected to respective switches by a CTI link. In typical operations known to the inventor, T-Server software provides routing and other intelligence to PBXs and other telephony switches where applicable. T-Server capability may be hosted and maintained by an enterprise operating one or more communication centers adapted to service customers of the enterprise. Likewise, associates working in one or more centers may, from time to time, collaborate by telephone and/or data terminal over the operating network.
In this example there are three illustrated parties as was described above with reference to FIG. 1. These are a first calling party 202 having a data terminal 215 and a telephone 218; a second calling party 204 having a data terminal 219 and a telephone 216; and a third party 203 having a data terminal 220 and a telephone 217. In this case, the third party 203 is not considered a calling party for this example as the party is �brought in� to a session with the first two parties and does not physically place a call. However, in another example, any of the illustrated parties may be considered a calling party if they physically initiate addition of another party to a multiparty session.
At step 407, party 2 decides to add an additional party to the session and initiates a call to a third party through the second switch. At this step or immediately prior, P1 may be placed on hold while P2 places the call. At step 408, a dialing event occurs at the location of P2. At step 409, a ringing event occurs at the switch location of P3, which is the same switch monitoring P2. At step 410, P3 answers and is connected to switch 2. At step 411, P3 is connected to P2, and at step 412 both parties are connected to P1 through switch 1. A SIP message containing the identification of P3 and a notification of a new state of �party added� is generated on behalf of a P1 representation at the second switch and is sent to the first switch over a data network supporting SIP messaging.
At step 414, switch 1 receives the message and notes the event �party added to session� and the identification of the added party. The notification may be displayed for P1 on a telephone display on a hand-held device, or by way of pop-up display on a connected data terminal if one is used.
