摘要： PROBLEM TO BE SOLVED: To enable a public mobile terminal to utilize both a public mobile communication service and an extension service while protecting a SIP message by means of IPsec.
SOLUTION: An indoor call control apparatus which receives an INVITE message from a public mobile terminal is provided with a call arrival destination determination table that determines whether a call arrival destination is an indoor terminal or not. If it is the indoor terminal, a Route header is deleted from the INVITE message and the relevant message is transmitted to a call arrival destination terminal. If the call arrival destination is not the indoor terminal, based on contents of the Route header, the INVITE message is transmitted to a serving-call session control function (S-CSCF) of a call originating terminal.

摘要： PROBLEM TO BE SOLVED: To automatically acquire a wavelength which an ONU can use by each ONU negotiating with OLT when initial setting in a PON system by a WDM.
SOLUTION: A wavelength usable for the negotiation of wavelength assignment is fixed as a default and an ONU newly connected uses the wavelength first. An OLT 200 is equipped with a plurality of light sources usable for downstream communication. On the other hand, the ONU 300 is equipped with a wavelength variable light source which has a wavelength variable filter capable of selectively the receiving light of one of the wavelengths usable for the downstream communication and can selectively emit the light of one of a plurality of wavelengths usable for upstream communication. The ONU 300 uses a transmission wavelength for negotiation (for example, λu32) to transmit a wavelength assignment request 1000 to the OLT 200. The OLT 200 selects a wavelength λu1 assigned from unused wavelengths and transmit wavelength information to the ONU 300. The OLT 200 and the ONU 300 perform the communication of a user signal by using the informed wavelength.
