Systems and methods for providing an intelligent network (IN) service to transparently establish a mid-call conference without requiring an intermediate hold state
First Claim
1. A method for providing an Intelligent Network (IN) service to transparently establish a mid-call conference using a Mobile Station (MS) while said MS is communicating with a second telephony device, said method comprising the steps of:
- querying a Home Location Register (HLR) for subscriber information associated with said MS, said subscriber information identifying whether said IN service is to be provided to said MS;
sending an IN service activation request to a Service Control Point (SCP);
receiving a Prompt&
Collect_User_Information command from said SCP, said command instructing said MSC to monitor said control channel for the transmission of dialed digits from said MS monitoring in a Mobile-services Switching Center (MSC) for the transmission of dialed digits over a control channel associated with said MS, said dialed digits identifying a third telephony device;
sending an acknowledgment message to said SCP, said acknowledgment message including said dialed digits received over said control channel associated with said MS;
receiving a request from said SCP to establish a call connection to said third telephony device, said request including said dialed digits;
establishing a call connection to said third telephony device; and
joining said third telephony device in conference with said MS and said second telephony device, thereby establishing a conference call between said MS and said first and second telephony devices without requiring an intermediate hold state of an existing call connection between said MS and said second telephony device.

Abstract
Systems and methods related to providing an Intelligent Network (in) service to transparently establish a mid-call conference using a Mobile Station (MS), without requiring an intermediate hold state of an existing call connection between the MS and a second telephony device; such systems and methods can be adapted to implementation in any wireless communications network, such as a Global Services for Mobile Communication (GSM) network. In an exemplary embodiment, a wireless communications network adapted to provide the IN service includes a Mobile-services Switching Center (MSC), and a Service Control Point (SCP), wherein the MSC is operative to send a request to the SCP to activate the IN service, and the SCP is operative to send a Prompt&Collect_User_Information command to the MSC. The Prompt&Collect_User_Information command instructs the MSC to monitor a control channel for the transmission of dialed digits from the MS; the dialed digits identify a third telephony device to be joined in conference with the MS and a second telephony device. The MSC sends an acknowledgment message to the SCP upon receipt of the dialed digits; the acknowledgment message includes the dialed digits. The SCP then controls the establishment of a call connection to the third telephony device, using the dialed digits, by sending a call setup request to the MSC.
