System and method for providing early ringback by a home legacy mobile station domain network
First Claim
1. A method of providing call progress to a calling party, comprising:
- receiving a circuit-switched call origination message in a home legacy mobile station domain, wherein circuit-switched the call origination message specifies a destination terminal device having a directory number assigned with the home legacy mobile station domain;
identifying a serving legacy mobile station domain in which the terminal device is registered;
transmitting, from the home legacy mobile station domain to the serving legacy mobile station domain, a call origination message that requests the terminal device to a call with the calling party;
receiving, by the home legacy mobile station domain from the serving legacy mobile station domain, a first message that requests the home legacy mobile station domain to provide a call progress signal to the calling party; and
providing, by the home legacy mobile station domain, a first call progress signal to the calling party.

Abstract
A system and method of providing call progress to a calling party is provided. A circuit-switched call origination message is received in a home legacy mobile station domain. The call origination message specifies a destination terminal device having a directory number assigned to the home legacy mobile station domain. A serving legacy mobile station domain in which the terminal device is registered is identified. The home legacy mobile station domain transmits to the serving legacy mobile station domain a call origination message. The home legacy mobile station domain receives from the serving legacy mobile station domain a first message that requests the home legacy mobile station domain to provide a call progress signal to the calling party. The home legacy mobile station domain provides a call progress signal to the exchange.

8. A computer-readable medium having computer-executable instructions for execution by a processing system, the computer-executable instructions for performing a method of providing call progress to a calling party, comprising:
-
instructions for interpreting a circuit-switched call origination message in a home legacy mobile station domain, wherein the circuit-switched call origination message specifies a destination terminal device having a directory number assigned to the home legacy mobile station domain;
instructions for identifying a serving legacy mobile station domain in which the terminal device is registered;
instructions for constructing and transmitting, from the home legacy mobile station domain to the serving legacy mobile station domain, a call origination message that requests the terminal device to join a call with the calling party;
instructions for receiving, by the home legacy mobile station domain from the serving legacy mobile station domain, a first message that requests the home legacy mobile station domain to provide a call progress signal to the calling party; and
instructions for providing, by the home legacy mobile station domain, a first call progress signal to the calling party. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A telecommunications system for connecting a circuit-switched calling party and a terminal device registered in a legacy mobile station domain, comprising:
-
a serving legacy mobile station domain in which the terminal device is registered; and
a home legacy mobile station domain having a directory number of the terminal device assigned thereto that receives a circuit-switched call origination message from the calling party and transmits a call origination message to the serving legacy mobile station domain that requests the terminal device to join a call with the calling party and that, in response to receipt of a first message from the serving legacy mobile station domain that requests the home legacy mobile station to provide call progress to the calling party, provides a first call progress signal to the calling party. - View Dependent Claims (16, 17, 18, 19, 20)
