    摘要: In the Mobile IPv4 network in the present invention, FA control servers (7a, 7b) that process only Mobile IP signaling, and IP tunnel routers (8a, 8c), being an IP tunnel endpoint, which also function as a default router with respect to a mobile node MN, form an FA function (referred to as a virtual FA). Further, an HA control server (9) that processes only Mobile IP signaling, and an IP tunnel router (8b), being an IP tunnel endpoint, form an HA function (referred to as a virtual HA). Here, the relation between the FA control servers (7a, 7b) and the IP tunnel routers (8a, 8c), and the relation between the HA control server (9) and the IP tunnel router (8b) are such that the former is a Media Gateway Controller (MGC) and the latter is a Media Gateway (MG). The FA control server (7a) notifies a mobile node MN (2) of the own address as an FA care-of address, in the form of a regular broadcast or query response. The IP tunnel router (8a) constituting the virtual FA notifies the mobile node MN (2) of an address, being a default router, in the form of a regular broadcast or query response.

    摘要: A small and economical voice packet assembling/disassembling (PAD) apparatus, which includes only one packet assembler/disassembler for a plurality of channels. The packet assembler receives coded voice data from a plurality of CODECs provided for each channel, and assembles voice packets by using the coded voice data. The packet disassembler disassembles voice packets to coded voice data and supplies them to a plurality of CODECs provided for each channel.
