Patent number: 8150364Abstract: 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).Type: GrantFiled: October 13, 2009Date of Patent: April 3, 2012Assignee: TeleCommunication Systems, Inc.Inventors: Richard Dickinson, John Gordon Hines, Jonathan Croy

Patent number: 8059789Abstract: ESQK and/or ESRK (ESxK) number pool exhaustion and reuse errors are eliminated by replacing the ESxK identifier with an emergency services pseudo key (ESPK) identifier. A positioning center (MPC/VPC) replaces an ESxK received with a query with a ESPK in a return message. The ESPK is either a unique 10-digit number or unique alpha-numeric identifier that can be used to re-query the source of dynamic ALI data. The ESPK may be generated using, e.g., unique prefixing, suffixing, or randomizing. The ESPK is a non-constrained, unique identifier that preferably remains unique for the call instance over an extended period of time. The ESPK is used for any subsequent ALI request for the call. Each time a positioning center receives a query with ESPK, it is directly associated with, and returns, the updated location for the original emergency call, regardless of whether or not the original ESxK was reallocated to another emergency call.Type: GrantFiled: December 1, 2006Date of Patent: November 15, 2011Assignee: TeleCommunication Systems, Inc.Inventors: John Gordon Hines, Jonathan Croy, Roger Stuart Marshall

Patent number: 7907551Abstract: 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.Type: GrantFiled: August 15, 2006Date of Patent: March 15, 2011Assignee: TeleCommunication Systems, Inc.Inventors: Jon Croy, John Gordon Hines, Darrin Johnson

Publication number: 20100323674Abstract: An area event handler informs when a target mobile enters or leaves a network covering a pre-defined target area, and re-aims an original area event request. When the event occurs, the mobile sends a location report to an initiator of the request. A PLMN list with estimated geographic coverage areas is stored in a Home GMLC, and sent to each relevant mobile. When a mobile enters new network coverage, it uses this list for network access selection. When the Home GMLC discovers that the currently visited PLMN does not serve the original target area, it modifies the area event to the that mobile, so that the Home GMLC will be notified when the target mobile once again enters a PLMN that serves the original target area. Then, after being so notified, the Home GMLC re-sends the original area event location service request to the target mobile.Type: ApplicationFiled: July 19, 2010Publication date: December 23, 2010Inventors: Yinjun Zhu, John Gordon Hines

Publication number: 20100034122Abstract: 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.Type: ApplicationFiled: October 14, 2009Publication date: February 11, 2010Inventors: Jon Croy, John Gordon Hines

Publication number: 20080261619Abstract: 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.Type: ApplicationFiled: September 26, 2007Publication date: October 23, 2008Inventors: John Gordon Hines, Darrin Johnson, Jonathan A.

Publication number: 20080154966Abstract: An emergency services key (e.g., ESQK or ESRK) is guaranteed to be available from a limited size ESQK pool. A plurality of ESQKs are grouped into a pool of emergency service keys “ESQK Pool ID”, each including anywhere from 1 to N number of ESQKs. Each ESQK preferably has a “Timestamp”, information relating to the specific emergency E911 call (“Call Data ID”), a guard timer, and an optional hold timer. The ESQK having a Call Data ID=“NULL”, and having the oldest Timestamp, is chosen for selection. If no such ESQK has both Call Data ID=NULL and the oldest Timestamp is found, then the ESQK with merely the oldest Timestamp is selected. The timestamp is reset to a current time plus a guard timer, or hold timer if desired.Type: ApplicationFiled: November 27, 2007Publication date: June 26, 2008Inventors: Gerhard Geldenbott, Yinjun Zhu, John Gordon Hines, Victor Burton

Publication number: 20080126535Abstract: A method and mechanism to allow a location server to initiate a user plane location service (e.g., SUPL defined by OMA) procedure to a user plane enabled device via Instant Messaging, or alternatively, via an existing SIP session if a multimedia session is already established. The location request is signaled to the user plane enabled device via a SIP INFO message. The location request uses SIP messaging to overcome firewall and other network security issues. Location using SUPL over SIP may be provided about a caller making an E911 emergency call. An Instant Message may be sent to the user plane enabled device, e.g., a VoIP wireless phone.Type: ApplicationFiled: December 14, 2006Publication date: May 29, 2008Inventors: Yinjun Zhu, John Gordon Hines, Roger Marshall, Fei Yang, Victor Burton

Publication number: 20070298765Abstract: The use of the VoIP emergency network for routing wireless E911 calls to a designated PSAP. In this embodiment, a mobile positioning center (MPC) assigns an ESRK per existing prior art, but uses the invention to route the call to the PSAP via the VoIP server and an ESGW. This relieves wireless carriers of the obligation to install and maintain expensive dedicated SS7 or CAMA trunks from each MSC to each selective router in the areas served by that MSC. Instead, wireless 911 calls can be consolidated by ESGW vendors, maximizing the efficiency of the dedicated trunks to the selective router by sharing those trunks with multiple MSCs.Type: ApplicationFiled: June 27, 2006Publication date: December 27, 2007Inventors: Richard Dickinson, John Gordon Hines, Jonathan Croy

Publication number: 20070274463Abstract: An emergency services key (e.g., ESQK or ESRK) is guaranteed to be available from a limited size ESQK pool, such that an available ESQK is always selected and associated with an ongoing emergency call with no measurable impact to existing calls, even if all ESQK pool members are marked as unavailable. A plurality of ESQKs are grouped into a pool of emergency service keys “ESQK Pool ID”, each including anywhere from 1 to N number of ESQKs. Each ESQK preferably has a “Timestamp”, and information relating to the specific emergency E911 call (“Call Data ID”). The ESQK having a Call Data ID=“NULL”, and having the oldest Timestamp, is chosen for selection. If no such ESQK has both Call Data ID=NULL and the oldest Timestamp is found, then the ESQK with merely the oldest Timestamp is selected.Type: ApplicationFiled: May 3, 2007Publication date: November 29, 2007Inventors: Gerhard Geldenbott, John Gordon Hines, Yinjun Zhu
