20120207091 | MOBILE COMMUNICATION METHOD AND RADIO ACCESS NETWORK APPARATUS - A mobile communication method according to the present invention includes the steps of: after a mobile station UE having RRC connection with the radio network controller RNC gets out of the coverage of the mobile communication system of WCDMA scheme, performing location registration to the mobile communication system of LTE scheme, issuing a notification to the radio network controller RNC by the exchange apparatus SGSN upon reception of predetermined signal, the notification implying that the mobile station UE performs the location registration to the mobile communication system of LTE scheme; and the radio network controller RNC releasing the resources for RRC connection without transmitting a signal to release the resources to the mobile station UE in response to the notification from the exchange apparatus SGSN. | 08-16-2012 |
20120208585 | MOBILE COMMUNICATION METHOD, RADIO ACCESS NETWORK APPARATUS AND EXCHANGE APPARATUS - A mobile communication method according to the present invention includes step A of instructing, by a radio access network apparatus of a first communication scheme, a mobile station having first radio connection established with the radio access network apparatus of the first communication scheme to switch to a mobile communication system of a second communication scheme, and step B of notifying the mobile station of a priority by the mobile communication system of the second communication scheme using a predetermined signal after the mobile station establishes second radio connection with a radio access network apparatus of the second communication scheme, the priority used to determine a communication system for camping-on by the mobile station. | 08-16-2012 |

20130016699 | MOBILE COMMUNICATION SYSTEM, NETWORK DEVICE, AND MOBILE COMMUNICATION METHODAANM Nakamura; YuichiroAACI Yokosuka-shiAACO JPAAGP Nakamura; Yuichiro Yokosuka-shi JPAANM Aoyagi; KenichiroAACI Yokosuka-shiAACO JPAAGP Aoyagi; Kenichiro Yokosuka-shi JPAANM Matsutani; HideyukiAACI Yokohama-shiAACO JPAAGP Matsutani; Hideyuki Yokohama-shi JP - In a handover procedure though which a bearer for the first communication call established between the first communication system and a mobile communication terminal is switched to a bearer for the first communication call established between the second communication system and the mobile communication terminal, the second communication system determines whether to establish the bearer for the first communication call between the second communication system and the mobile communication terminal based on whether the first communication call is established between the first communication system and the mobile communication terminal or the data amount of the first communication call established between the first communication system and the mobile communication terminal. | 01-17-2013 |
20130028187 | MOBILE COMMUNICATION SYSTEM, NETWORK DEVICE, AND MOBILE COMMUNICATION METHOD - During a transition procedure from a first communication system to a second communication system, when the priority of a second communication call, whose setup is requested, is the first priority, the second communication system does not set up the bearer of a first communication call between the second communication system and the mobile communication terminal, and notifies the first communication system that the setup of the first communication is not possible, but the setup of the second communication call is possible. When notified that the setup of the first communication is not possible, but the setup of the second communication call is possible, the first communication system aborts the handover procedure, and instructs the mobile communication terminal to switch to the second communication system by another procedure. | 01-31-2013 |
