Title: Mobile terminating l2tp using mobile ip data
Inventor: COMSTOCK DAVID
IPC: H04L29/06
Filed: 1999-12-14
Abstract: In accordance with embodiments of the invention, Mobile IP binding information is used to deliver mobile terminating packets using layer-2 tunneling. When terminating packets destined for a mobile node are received by a home network for the mobile node, the Mobile IP binding is used to obtain the address of a foreign network to which the mobile node is attached. A Layer 2 Tunneling Protocol tunnel is created between the home network and the foreign network, and an outgoing L2TP call is made from the home network to the foreign network. A call is made from the foreign network to the mobile node, and a PPP  session is established between the home network and the mobile node, via the Layer 2 Tunneling Protocol tunnel between the home network and the foreign network. After the PPP session is established the home network can optionally assign the mobile node a private IP address, and translate the home IP address labeling the terminating packets to the private IP address.

Filed: 2000-06-16
Abstract: When judging, for each preset section, whether an input signal is voice or other than voice, a single algorithm is used for judging even when a plurality of kinds of input signal frequency band and section length are available. A  unit length division circuit (20) divides a signal from an input terminal (10) into unit lengths (e.g., 2.5 msec) shorter than a frame length (e.g., 10 msec) for transfer to a band conversion circuit (30). The band conversion circuit (30) restricts a frequency band provided by an input signal having a frame length given by the unit length division circuit (20) to a frequency band that can be detected by a detection circuit (40) for transfer to the detection circuit (40). The detection circuit (40) judges whether an input signal on a frame basis from the unit length division circuit (20) falls in a voice section or a voiceless section and transfers the judging result to a unit length conversion circuit (50). The unit length conversion circuit (50) determines the judging result of a frame from a plurality of judging results, corresponding to respective frames, from the detection circuit (40) for outputting from an output terminal (60).
