Abstract:
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.
Abstract:
A technique evaluates overlapping request intervals, and from them determines a temporal reporting interval that satisfies requirements for all that overlap. The temporal reporting interval represents a temporal trigger used to best support multiple triggers on the same target, without modification or support by the target mobile. When multiple users, by chance request location triggered services on the same target mobile during the same period (A.2.), to minimize the usage of resources, the number of active triggers on a target mobile is reduced.
Abstract:
Locating satellites (e.g., GPS) are culled into a preferred group having a longest dwell time based on a time passing through an ellipsoid arc path through a cone of space, and communicated to mobile devices within a particular region (e.g., serviced by a particular base station). The locating satellites may be culled into a prioritized list. Each satellite is assigned an order of precedence based on a remaining dwell time within a primary inverted cone. Thus, a number 'N' of satellite's ephemeris data may be used, along with a preferred 'order of precedence' for secondary satellites to be used as backups as necessary.
Abstract:
Using wireless features, a public service agency is enabled to provide alert information to first responders. An automatic call back from the first responder triggers a voice call launching a location fix on the current location of the first responder. Preferably delivery confirmation that the responder has received the message is received. Once the location fix has been completed, then driving directions with map images are sent to the first responder based on their current location and desired destination for response.
Abstract:
Dynamically selecting and facilitating stored caller information to a communications recipient device with a communications event, based on communication recipient credentials (e.g. MDN, etc.), preferences outlined in a subscriber profile associated with a relevant calling device, and other variables, e.g., time of day, etc. A subscriber provisions subscriber preferences and subscriber information associated with users of a subscribing communications device in to a subscriber profile, for use during a communications event. Subscriber preferences place restrictive conditions on stored subscriber information that may be transmitted with a communications event initiated by a corresponding communications device. A content collection node dynamically selects customized caller information via a subscriber information content collection process. Customized caller information is transmitted to appropriate recipient devices with a corresponding communications event. In the event of a 911 communications event, customized caller information may be transmitted to emergency dispatch personnel via the legacy E2 query interface.
Abstract:
An i3 proxy module is provided within a 911 service provider network (e.g., at the VoIP positioning center) to respond to a VoIP i2 SIP INVITE destined for a PSAP having i3 architecture. The i3 proxy module responds to the VoIP i2 SIP INVITE by generating a VoIP i3 SIP INVITE with PIDF-LO and routing the same to the i3 emergency services routing proxy (ESRP) within the i3 network. Thus, an i3 SIP INVITE with PIDF-LO is sent from an i3 proxy module associated with an i2-based VoIP positioning center (VPC). Thus, legacy originating service provider (OSP) carrier networks are now enabled to route an emergency call to a PSAP having an i3 ESInet architecture.

Abstract:
A security broker (SB) that provides network based authorization of secure VoIP services, triggered upon attempted user access. The security broker (SB) intercepts a SIP transaction during session setup to transmit a network based security challenge to a SIP application attempting to access (secure) IP based services. A network based security challenge is transmitted to a participating SIP application on both the origination and termination legs of a SIP transaction. The network based security challenge prompts a SIP application to return subscriber authorization/authentication credentials (e.g. a username/password combination). If credentials returned by the SIP application are valid, the security broker (SB) authorizes the network to permit session completion, and access to secure IP services is granted. Alternatively, if credentials returned by the VoIP application are invalid, the security broker (SB) terminates the corresponding session attempt, hence preventing unauthorized access to (secure) IP based services.
Abstract:
An E-9-1-1 voice-over-IP (VoIP) solution is provided wherein a 911 call from a mobile VoIP device is routed directly to the correct Public Safety Answer Point (PSAP) via dedicated trunks, together with correct location information and call-back number. VoIP gateways are implemented locally, at least one per LATA, and accept VoIP packetized data inbound, and convert it to standard wireline voice calls. Calls are routed to an IP address at the VoIP gateway, which then egresses the call to a voice port at a selective router. Mid-call updating of location of a moving VoIP terminal is provided to a PSAP. The location of the VoIP is validated using HTTP based protocol by pushing location information to a VoIP location server, and comparing it against a geographic location database to confirm that a contained street address is valid.
Abstract:
Voice Over Internet Protocol (VoIP) devices are invited to a conference bridge (100) based on a pre-defined criteria for the conference bridge (e.g., passengers on a plane). The conference invite messages are transmitted using Internet Protocol, which they may or may not accept. The invited VoIP users may be determined based on their physical proximity to the initial caller and other pre-determined characteristics. A VoIP soft switch (102) includes conference bridges that eliminate the conventional requirement that they dial the phone number of another specific VoIP communications device. Instead, location informationrelating 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. Location and other information is then compared by the VoIP soft switch against other VoIP devices, to find potential VoIP conference participants.
