Abstract (in Japanese) (See Japanese page) 
(in English) NTT is proceeding with implementation of the Next Generation Network (NGN) that is based on the Internet Protocol (IP) and is integrated with the data and the voice communication. NGN is providing some additional services which are provided in PSTN such as call-waiting, call-forwarding, etc. Because some additional services will be provided by Application server (AS) specified in 3GPP, it is necessary to study on network functions. The specification in 3GPP defines the Initial Filter Criteria (IFC) and the interfaces between AS and other functions. However, although the additional services have the characteristic differences, this specification does not treat that problems and does not define the implementation method.
In this paper, we clarify some problems and propose the implementation method for AS coordination function of SIP server in NGN.
