Eliminated DTMF signaling in an integrated wireline-wireless system
First Claim
Patent Images
1. A call connection method in a communication system having integrated wireline and wireless sections, wherein the wireline section and the wireless section communicate via a mobility management interface and a GR-303 interface, the method comprising the steps of:
- communicating a called party'"'"'s number from the wireless section to the wireline section via the mobility management interface; and
performing off-hook immediate call setup at the wireline section once an off-hook signal is received from the wireless section via the GR-303 interface.

Abstract
An integrated wireless wireline system (IWWS) architecture without the requirement for dual-tone modulation frequency (DTMF) signaling to communicate a called party'"'"'s number from the wireless section to the wireline section, thereby expediting call setup and making it more reliable.

6. A method of communicating a called party'"'"'s number in a communication system having integrated wireline and wireless sections, the wireline section comprising a switch and an advanced intelligent network (AIN) service control point (SCP) communicating via an AIN link, and the wireless section communicates with the switch via a GR-303 interface and communicates with the AIN SCP via a mobility management interface, the method comprising the steps of:
-
upon receiving a call origination request from a calling wireless user, communicating the called party'"'"'s number from the wireless section to the AIN SCP via the mobility management interface; communicating a call origination response from the AIN SCP to the wireless section in response to the call origination request; upon receiving the call origination response, communicating an off-hook signal from the wireless section to the switch via the GR-303 interface; and performing off-hook immediate call setup at the switch upon receiving the off-hook signal.

7. An integrated wireline-wireless system connecting a calling wireless party with a called party identified by a called party number, the system comprising:
-
a wireless infrastructure communicating with the wireless calling party via an open air interface; and a wireline section comprising a switch and an Advanced Intelligent Network (AIN) Service Control Point (SCP), wherein the switch is connected to the wireless infrastructure via a GR-303 interface and is configured for off-hook immediate call setup upon receiving an off-hook signal from the wireless infrastructure via the GR-303 interface, and wherein the AIN SCP is connected to the wireless infrastructure via a mobility management interface to receive the called party number from the wireless infrastructure. - View Dependent Claims (8, 9, 10)
