    摘要: Systems and techniques are disclosed relating to wireless communications. The systems and techniques involve wireless communications wherein a packet data session may be established between a wireless communications device and a packet data serving node to support a network connection to a packet-switched network. The wireless communications device may be configured to receive a notification of an incoming call from a circuit-switched network even when the network connection is active.

    摘要: Techniques for performing registration in parallel with call establishment to reduce delay are described. A user equipment (UE) performs registration with a communication network, e.g., in response to a user placing an emergency call. The UE establishes the call in parallel with performing registration. The UE updates the call with information (e.g., verified UE identity and/or call back information) obtained from the registration by sending the information to a called entity/party such as a Public Safety Answering Point (PSAP) selected for the emergency call. The UE sends a first message to initiate registration, a second message to initiate establishment of the call, and a third message to update the call with the information obtained from the registration. The established call may be associated with the registration based on a common source IP address in the first, second and third messages and common dialogue information in the second and third messages.

    摘要: In a communication session in which data flows with encrypted data packets pass through a monitoring intermediary for data traffic control. The encrypted data packets include SPIs (Secured Parameter Indexes) which are used to identify SAs (Security Associations) for data decryption. During the initial signaling process for the communication session, the nodes seeking the communication session include the SPIs in the signaling messages and send the signaling messages through the monitoring intermediary which in turn matches the SPIs of the signaling messages with the corresponding SPIs extracted from the data packets. In enforcing data traffic control, the monitoring intermediary allows data flows to pass through if comparison matches in the SPIs are found. Otherwise, the data flows are rejected.

    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: Mobile unassisted dormant handoff in a wireless communication system supporting packet data communications. While in a dormant mode, a mobile node may change packet zones, wherein different packet zones are serviced by at least one different infrastructure element, without identifying the change to the system. The change in packet zone does not necessarily trigger establishment of a communication path for the mobile node until there is packet data ready for communication. In one embodiment, mobile assistance is adapted to the system, and is disabled at the mobile node by an indication in a system parameter message transmitted by the system and received by the mobile node.

    摘要: Techniques for performing handover in order to maintain call continuity for a user equipment (UE) are described. The UE may communicate with a first cell in a radio access network (RAN) for a packet-switched (PS) call, e.g., for Voice-over-Internet Protocol (VoIP) via High-Speed Packet Access (HSPA) in W-CDMA. The UE may send measurement reports to the RAN and may receive trigger from the RAN. The UE may establish a circuit-switched (PS) call with the first cell while the PS call is pending at the first cell. The PS call and the CS call may be for a voice call, and the UE may switch data path for the voice call from the PS call to the CS call and then terminate the PS call. The UE may then perform handover of the CS call from the first cell to a second cell, which may not support VoIP.
