    摘要: In a communications system where a mobile node seeks to establish contact with a server node within or outside the home network of the mobile node by first providing the general location information and the server type of the server node to a DHCP (Dynamic Host Configuration Protocol) server. The DHCP server then matches the provided information with its record in storage to arrive at an IP (Internet Protocol) address of the sought server node. The DHCP server then sends the IP address to the mobile node, thereby allowing the mobile node to directly access the server node.

    摘要: Establish and maintain an IMS emergency call when a UE moves (roams) to a visited network. Receiving at a first network entity (Location and Routing Function, LRF) a request for location of a user equipment, UE, from a second network entity (emergency call session control function, E-CSCF); determining the location of the UE (by seding a retrieve location message from the E-CSCF to the LRF); assigning a temporary identity (i.e. an Emergency Service Query Key, ESQK, or Emergency Service Routing Key, ESRK) for the UE; sending the temporary identity (i.e. ESQK or ESRK) and the location of the UE to the second network entity (E-CSCF); receiving a verified information for the UE from the second network entity (i.e. receiving a SIP re-invite or SIP update message); and associating the verified information with the temporary identity (i.e. ESQK or ESRK) for the UE.

    摘要: 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.

    摘要: IMS (VoIP) emergency call session with parallel registration and call establishment. An apparatus (and a method) for a first network entity (E-CSC, 254) in a visited communication network (130), the apparatus comprising: at least one processor to establish (7, 8, 9, 10, 11) a call for a user equipment, UE, based on a temporary identity for the UE (by sending a SIP INVITE message comprising an emergency indication and the temporary identity to a P-CSCF and further to an E-CSCF, by retrieving location from an LRF, 256, by obtaining an interim location, by returning a location from LRF, i.e. "ESQK", and by forwarding a SIP INVITE from LRF to PSAP or an ISUP IAM or an MF Call + ESQK, and by completing an emergency sessio establishment), by receiving (15) a verified identity of the UE or a further UE (110) after establishing (12) the emergency call (using a SIP Re-invite or SIP Update message), and to forward (16) the verified identity of the UE to a second network entity (256), by forwarding the SIP Re-invite or Update message through the P-CSCF, to the E-CSCF and to the LRF.
