Patent number: 9148769Abstract: A mobile device/UE identifies calls to or callbacks from a Public Safety Access Point (PSAP) in order to provide priority handling. When the UE does not detect that the call being made is an emergency call, then the network facilitates identification during call establishment of the emergency nature. The network identifies the call as emergency call in a SIP response by setting the Priority header to distinctive value (e.g., “emergency-call”) or the “P-Asserted-Identity to a distinctive value (e.g., urn:services:sos). When PSAP chooses to call back the mobile/UE, the mobile/UE can terminate any ongoing calls and accept this call from the PSAP and can disable other supplementary services (e.g., call waiting, three-way calling etc.) during the call. A P-Asserted-Identity of the incoming call is set to a distinctive location associated with PSAP (e.g., urn:services:sos). Alternatively, the incoming call has a Priority header set to a distinctive value (e.g., “emergency”, “emergency-callback”).Type: GrantFiled: April 30, 2009Date of Patent: September 29, 2015Assignee: QUALCOMM IncorporatedInventor: Arungundram C.

Patent number: 8942660Abstract: Techniques for supporting handover of an emergency call between wireless networks are described. A UE may communicate with a first wireless network (e.g., a 3GPP E-UTRAN) for an emergency call and may receive an indication to perform handover to a second wireless network (e.g., a CDMA2000 1xRTT network). In an aspect, the UE may send a message including an emergency indication (an emergency global number, or a reserved emergency number, or some other indication) to initiate handover to the second wireless network. A designated network entity may recognize the emergency call based on the emergency indication and may map the emergency indication to a local emergency number or an Emergency Session Transfer Number for SRVCC (E-STN-SR), which may be used to establish a new incoming call leg to a network server anchoring the emergency call. The UE may then communicate with the second wireless network via the network server for the emergency call after handover.Type: GrantFiled: June 3, 2010Date of Patent: January 27, 2015Assignee: QUALCOMM IncorporatedInventors: Stephen W.

Patent number: 8787249Abstract: In a wireless communication system having multiple access nodes, a home agent (HA) maintains home address (HoA) for a mobile node so that an IP session can be established. As the mobile node moves within a coverage area of various access nodes, the mobile node can establish a secure relationship with a local access gateway and thereby register a local IP address, referred to as a care-of-address (CoA), with the HA. Mobile IP protocol can be established so that multiple sessions can be conducted. In maintaining policy and charging control (PCC), HA informs a policy and charging rules function (PCRF), which in turn can then send the appropriate PCC rules (e.g., IP flows and related policies) to a policy and charging enforcement function (PCEF) for a particular access gateway. Coordination necessary to associate CoA and HoA can further include filter information as to application can run on a particular interface.Type: GrantFiled: February 4, 2009Date of Patent: July 22, 2014Assignee: QUALCOMM IncorporatedInventors: Gerardo Giaretta, Jun Wang, Kalle I.
