Publication number: 20080108356Abstract: When a network pages the temporary user mobile identifier of a mobile station, the mobile station sends a response to the network. Next, the network checks the authenticity of the user using a ciphering key, corresponding to the temporary user mobile identifier and a random number. If the temporary user mobile identifier is authenticated, a normal incoming call acceptance procedure is executed. If the mobile station is authenticated although the temporary user mobile identifier is wrong, the network reassigns a new temporary user mobile identifier to the mobile station and stops the current communication. In communication, the network and the mobile station mutually notify encipherment-onset time and negotiate about encipherment manner with each other. In addition, diversity handover is commenced upon a call attempt. Furthermore, if a branch replacement is necessary, the current branch is replaced by new branches capable of executing the diversity handover.Type: ApplicationFiled: May 30, 2007Publication date: May 8, 2008Applicant: NTT Mobile Communications Network, Inc.Inventors: Motoshi Tamura, Mutsumaru Miki, Akiko Okamoto, Kenya Kusunose, Akihiro Uchikoshi, Daisuke Igarashi, Katsuhiko Yamagata, Takaaki Sato, Junichiro Hagiwara, Yasuyuki Watanabe, Takuya Hamajima, Masafumi Hata, Nobutaka Ishikawa, Yoshiyuki Yasuda, Kazufumi Yunoki, Nobuhide Uchiyama

Publication number: 20060281481Abstract: Time required before PoC communication starts, in the case where a communication channel on the destination side has not been established, is shortened, and convenience of users is enhanced. A request for establishing a communication channel used for PoC communication is sent from a terminal TA. Immediately after receiving this request, call processing for establishing a communication channel to a terminal TC other than the terminal TA is started. In parallel with this call processing, processing after sending a response to the request is performed. Thereby, response to a communication channel connection request, SIP Registration processing and Invitation processing on the originating side and the processing on the destination side are performed in parallel, so that connection time can be shortened, and PoC communication can be started early.Type: ApplicationFiled: May 23, 2006Publication date: December 14, 2006Applicant: NTT DoCoMo, Inc.Inventors: Yosuke Hayashi, Mutsumaru Miki, Naomasa Yoshida
