  • Publication number: 20170245113
    Abstract: A method of selecting a location determination method for a mobile device within a wireless communication network. For example, the method may be selected based upon how the mobile device accessed the wireless communication network and the capabilities of the mobile device. Thus, possible technologies for determining the location of the mobile device include, but are not limited to, using a Location Retrieval Function (LRF), an Enhanced Serving Mobile Location Center (E-SMLC), a Global Positioning System (GPS), triangulation and accessing a National Emergency Address Database (NEAD). Additionally, multiple methods and/or technologies may be used to determine the mobile device's location and the method or methods may be selected based upon levels of trust with respect to the results.

  • Patent number: 9668090
    Abstract: An E-CSCF receives a Session Initiation Protocol (“SIP”) invitation message initiating an emergency communication session from a calling device. The E-CSCF generates an information request message based on the received SIP message and sends the information request message to a location server. The location server determines a geographical location of the calling device and uses the geographical location to determine a destination emergency response center, such as a Public Safety Access Point (PSAP). The location server provides location information for the destination PSAP to the E-CSCF. The E-CSCF generates a modified SIP invitation message using the presence information and sends the modified SIP invitation message to an emergency services network where it is routed to the emergency response center.

  • Publication number: 20170150336
    Abstract: A wireless emergency alert system (also known as a wireless emergency alert system, or “WEA,” and formerly known as a commercial mobile alert system, or “CMAS”) receives a geotargeted federal alert that is to be delivered to mobile devices within a defined geographic region. A database of locations of access points is utilized by the system to identify those access points that are likely present in the defined region. The system identifies mobile devices that have an ongoing connection (e.g. IP multimedia subsystem (IMS) session) with the identified access points, in part by maintaining and accessing a look-up table containing location information for the access point and connected mobile devices. In addition, the system tracks mobile devices that no longer have an ongoing session and deregisters the appropriate mobile devices in the look-up table.

  • Publication number: 20160360431
    Abstract: A system and method for performing an emergency call route failover between an Emergency Call Session Control Function (E-CSCF) and multi-homed remote end-point functions such as Border Gateway Control Function(BGCF)/Media Gateway Control Function (MGCF) or Interconnection Border Control Function (IBCF) in an Internet Protocol Multimedia Subsystem (IMS) uses Session Initiation Protocol (SIP) and/or Domain Name System (DNS) methods. The E-CSCF and/or a DNS server monitors the availability of the remote end-points to create a peer list of route options. The E-CSCF or the DNS server selects a route option from the peer list to route an emergency call to an appropriate Public Safety Answering Point (PSAP). In the event that the route option fails, the E-CSCF fails over to the next available route option to route the emergency call.

  • Publication number: 20160105780
    Abstract: A communication device may transmit messages to an Internet Protocol Multimedia Subsystem (IMS) network through an untrusted non-3GPP radio access network (RAN). A process to be implemented on a communication device may include generating a message having a location identifier (ID) that is indicative of a current location of the communication device, and transmitting the message, through an untrusted non-3GPP RAN, to a node within the IMS network. A process to be implemented on one or more nodes of the IMS network may include receiving, from a communication device and via an untrusted non-3GPP RAN, a message having a location ID, and in response to receiving the message, estimating a current location of the communication device based at least in part on the location ID.

  • Patent number: 9232380
    Abstract: A system and method to determine a type of wireless network that is to be used for an emergency communication session that is initiated at a mobile device. A Session Initiation Protocol (SIP) header is modified to introduce an emergency call mode preference (ECMP) field into the header. When a mobile device registers a session with an IP Multimedia Subsystem (IMS), the ECMP field is populated by the service provider with information that conveys the preferred network to use when an emergency communication session is initiated by a user of the mobile device. In the event of a subsequent request to start an emergency communication session using the mobile device, the mobile device utilizes the preferred network to establish communication.
