| 20100034122 | Voice over internet protocol (VoIP) location based conferencing - A Voice Over Internet Protocol (VoIP) device uses its location to narrow down known and unknown potential VoIP third parties meeting the user's criteria, based on their physical proximity to the initial caller and other pre-determined characteristics, to join in a phone conference. A VoIP soft switch includes conference bridges that eliminate the conventional requirement that they dial digits for a direct link with another specific VoIP communications device. Instead, location information relating to the initial VoIP user is passed to the VoIP conference bridge, either from the user's VoIP communication device or from their respective location server. The location information is then compared by the VoIP soft switch against other VoIP devices to find potential VoIP users within a defined geographic region surrounding the initial VoIP user. Those VoIP users matching the criteria are sent an Invite message to join the conference, which they may or may not accept. | 02-11-2010 |
| 20100272242 | Voice over internet protocol (VolP) location based 911 conferencing - Voice Over Internet Protocol (VoIP) emergency calls to an Emergency Response Center (ERC) are handled through a VoIP conference bridge on a VoIP service provider's soft switch. The soft switch works with a VoIP positioning center (VPC) to obtain location information, which is compared against a PSAP database to find an initial best-appropriate PSAP for the location of the emergency caller. The PSAP is issued an Invite message to join the conference, establishing an emergency call. Third parties such as police, ambulance may be issued Invite messages to join the conference. Cold transfers are avoided by Inviting participants to join a single emergency conference rather than passing an emergency call from party to party (e.g., from PSAP to police to ambulance, etc.) The PSAP, other emergency responders, and even the initial VoIP emergency caller may leave and rejoin the VoIP conference without dropping the conference between the others. | 10-28-2010 |

| 20100046489 | Enhanced E911 network access for a call center using session initiation protocol (SIP) messaging - A switched emergency call (e.g., a 911 call, an alarm company call) forwarded by a telematics call center is converted into a session initiation protocol (SIP) packetized phone call at the call center, and routed over an IP network, for presentation to an emergency services gateway, which connects to a selective router via dedicated circuits, gaining full access to the Enhanced 911 network. This provides a PSAP receiving a call from a telematics call center or other call center with all features available in an Enhanced 911 network, e.g., callback number of the 911 caller, and location of the 911 caller. Location of the caller is provided using a VoIP positioning center (VPC), queried from the call center. In this way, the switched emergency call is converted into a SIP packetized phone call and routed without further passage through the public switched telephone network (PSTN). | 02-25-2010 |
| 20110019664 | Emergency alert for voice over internet protocol (VoIP) - A voice over Internet Protocol (VoIP) positioning center (VPC) is implemented in configuration with support from a text-to-voice module, emergency routing database, and VoIP switching points (VSPs) to allow a public safety access point (PSAP) or other emergency center to effectively communicate the nature of an emergency alert notification and the area of notification to the VoIP positioning center (VPC). The inventive VPC in turn determines which phones (including wireless and/or VoIP phones) are currently in the area for notification, and reliably and quickly issues the required warning to all affected wireless and VoIP phones. | 01-27-2011 |

| 20080249796 | Voice over internet protocol (VoIP) location based commercial prospect conferencing - An automated system for matching a calling potential buyer on a VoIP phone with a prospective commercial business within their current area. The buyer may accept or reject connection with a best available prospective business to be automatically presented with the next prospective business as ranked by the presenting business locating service. The location of the potential buyer is provided or obtained, and the best available business selected from the database based on proximity to the buyers current location. A secondary prioritization may be applied to highest bidding businesses. The business finding module establishes a VoIP conference bridge, and invites the buyer and best available business. A pre-recorded message may be played into the conference bridge or directly to the buyer or business. The businesses may be ranked based on how much they pay or bid to be presented first to potential buyers. | 10-09-2008 |
| 20080259908 | Location object proxy - The function of determination of location is separated from the function of gathering information based on determined location by use of a Location Object (LO) proxy between an initiating VoIP capable device and a positioning center. The LOProxy queries an appropriate location database using a location key, and injects a PIDF-LO into a routing SIP message otherwise without location. A SIP request without location is received from a VoIP capable device. The SIP request contains messages indicating the type of location generator or service needed. A location key (like a telephone number or SIP URI), in addition to the type of location generator or service needed, is included in a SIP request. A location object (LO) broker may be used between a routing SIP message and a positioning center to direct a routing SIP message to an appropriate one of a plurality of location object (LO) proxies. | 10-23-2008 |
| 20080261619 | Injection of location object into routing SIP message - The function of determination of location is separated from the function of gathering information based on determined location by use of a Location Object (LO) proxy between an initiating VoIP capable device and a positioning center. The LOProxy queries an appropriate location database using a location key, and injects a PIDF-LO into a routing SIP message otherwise without location. A SIP request without location is received from a VoIP capable device. The SIP request contains messages indicating the type of location generator or service needed. A location key (like a telephone number or SIP URI), in addition to the type of location generator or service needed, is included in a SIP request.
