Abstract: A switching module can route packets between a network fabric and a local network, both of which form a closed network such as a vehicular network. The switching module provides local network management functions, and handles packet transfers between the local network and the network fabric. The switching module uses network information, which can include information about packet content type and network topology, to determine a packet's priority, and an appropriate switching protocol to use for processing and routing packets.

Abstract: A telephone service method that provides subscribers with the functionality of an extra telephone line during data/Internet sessions. Each subscriber has a unique telephone number Dns that can be dialed by anyone with access to the PSTN. When the Dns is dialed the call will be routed via the PSTN to the ILTD server. The ILTD server upon receiving the call attempt from the Dnc will analyze the dialed number (Dns) and determine if the subscriber's computer is able to receive the telephone call. If the subscriber's computer is actively engaged in an Internet Protocol session, with the ILTD client software running, the ILTD server will connect the call over the Internet to the ILTD client software. The ILTD client software will activate the subscriber's sound card and the microphone to play audio and receive input from the microphone to allow the subscriber and the calling party to have a full duplex telephone conversation (i.e. using voice-over-IP technology).

Abstract: An emergency call (e.g., a 911 call, an alarm company call) forwarded by a telematics call center is routed over the switched PSTN to a Voice Over Internet Protocol (VoIP) call server, where the switched call is converted to a session initiating protocol (SIP) packetized IP call for presentation to an emergency services gateway, which reconverts the call to TDM and connects to a selective router via dedicated circuits, gaining full access to the Enhanced 911 network. This provides a PSAP receiving a call from a telematics call center or other call center with all features available in an Enhanced 911 network, e.g., callback number of the 911 caller, and location of the 911 caller. Location of the caller is provided using a VoIP positioning center (VPC).

Abstract: An exploitation of the proper classification of conventional call processing states into categories, each category corresponding to one of the call states of the SIP finite-state machine (FSM), yields simplified design, implementation, and operation of heterogeneous call processing. A separate FSM for the SIP-categorized call states running in parallel with a conventional port event processing (PEP) FSM, implements a VoIP Local Call Controller by passing events between the SIP-type FSM and the PEP FSM only at the points where a transition between SIP categories occurs. The SIP FSM does not require notification of PEP FSM transitions not affecting the SIP call state. For this reason, none of the code associated with the transitions between PEP FSM states within the same major state category requires any modification. Consequently the integration of VoIP and PEP call processing can be done more simply, and at dramatically-reduced cost in software development, support, and maintenance.

In this manner, necessary contextual information may be readily available for the routed destination at the time of the call connection and thus the routed destination can provide a faster service.

Abstract: An auxiliary call control component is coupled to a computing system alerts the computing system of an incoming call in instances where the computing system is not capable of processing the incoming call. When the auxiliary call control component receives an incoming call, the auxiliary call control component determines whether the coupled computing system is in a proper state suitable for processing (e.g., “picking up”) the incoming call. If the computing system is not in the proper state, the auxiliary call control component accepts the incoming call, signals the computing system to enter the proper state, and informs the computing system of the incoming call. When placed in the proper state, the computing system may retrieve the incoming call to allow the user to receive to the incoming call at the computing system.

Abstract: The present invention relates to the network architecture and billing method of the packet switch data service of the CDMA Intelligent Network (IN) user. Because the CDMA mobile switch uses the 3G1x packet switch data service, the billing of the service bypasses the MSC calling control layer, the billing can only be implemented by the PCF. In the PCF, there are only two billing methods: by amount of data method and the post service method. The non-real time post billing methods are not suitable for the IN prepaid users. Thus, the present invention illustrates new network architecture and billing method of the packet switch data service. The billing interface (PCF-SCP) is provided between the PCF and the SCP. The billing interface transfers at least three messages between the PCF and the SCP, to implement the real time or periodic billing for packet switch data service.

Abstract: A wireless device initially has simultaneous circuit switched (CS) and packet switched (PS) services with a non-UMTS network. With the CS and PS services ongoing, the non-UMTS network transmits a HANDOVER TO UTRAN COMMAND message to the wireless device to perform a handover to UTRAN procedure. The HANDOVER TO UTRAN COMMAND message excludes information used for handing over the PS signaling connections to the UTRAN so that only CS signaling connections are handed over. The wireless device receives and parses the HANDOVER TO UTRAN COMMAND message to determine what signaling connections are being handed over. Upon determining that only CS signaling connections are being handed over, a radio resource control (RRC) layer within the wireless device informs an upper layer within the wireless device that no PS radio access bearers or no PS signaling connections are present.
