  • Patent number: 9179280
    Abstract: A system and method for providing location information to a public safety answering point may include receiving, at a network access point, an emergency 911 call signal including GPS location information and mobile directory number of a wireless device. The GPS location information and mobile directory information may be communicated to a selective muter associated with a public safety access point servicing an area including the network access point. The network access point may be a WiFi access point. The access point address information may be communicated using a type II caller ID data packet after the public safety answering point goes off-hook By communicating both the access point address information and GPS location information, both PSAPs that are configured as E911 Phase I and E911 Phase II may display address location information of an emergency 911 caller.

  • Patent number: 9031207
    Abstract: A system and method for communicating location information of a VoIP subscriber to a public-safety answering point may include receiving an E-911 telephone call from a VoIP telephone. Location information associated with the VoIP telephone stored in a database may be requested. The location information may be received in a signal formatted substantially the same as a signal format for communicating caller identification information. The location information may be displayed at a public-safety answering point. In one embodiment, the location information may be displayed on a video display.

  • Patent number: 8982871
    Abstract: A system and method for providing location information to a public safety answering point from a softphone may include receiving, at a network access point, an emergency 911 call from the softphone. The emergency 911 call may be communicated to a public safety answering point. In response to a call connection message being received, an address location of the network access point to which the softphone is in communication in placing the emergency 911 call to the public safety answering point may be communicated in a type II caller ID data packet. The softphone may generate the type II caller ID data packet with the address location in a data field, such as a data field typically used for name information of a caller.

  • Patent number: 8824999
    Abstract: A system and method for registering the contact information of mobile devices with a service 911 service is presented. In one embodiment, a mobile switching center receives the contact information of a mobile device. If the mobile switching center determines that the mobile device is not located within a particular wireless sub-network, such as, but not limited to, a wireless sub-network associated with an area code registered to the mobile device, the mobile switching center generates a reverse 911 registration text message and transmits the reverse 911 registration text message to the mobile device. A user of the mobile device may then transmit the reverse 911 registration text message to a local reverse 911 database to have the contact information associated with the mobile device added to the local reverse 911 database.

  • Patent number: 8295827
    Abstract: A system and method for establishing a signal parameter threshold for switching between communications protocols by a multimode handset may include providing cordless telephones of different models. A dropout point at which a communications signal of each of the cordless telephones deteriorates below a predetermined level may be determined. At least one signal parameter of the communications signal at the determined dropout point of each of the cordless telephones may be measured and collected. The signal parameter(s) associated with the cordless telephone having the shortest range at which the associated dropout point may be determined so that a multimode handset may be established with the signal parameter(s) to cause the multimode handset to switch communications protocols in response to the multimode handset crossing a signal parameter threshold level defined by the predetermined signal parameter(s) when communicating with a base unit of a cordless telephone.
