Mobile communication method and radio access network apparatus

摘要

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.

1. A mobile communication method comprising the steps of:
after a mobile station having radio connection with a radio access network apparatus leaves a mobile coverage area of a Wideband Code Division Multiple Access (WCDMA) mobile communication system, performing, by the mobile station, location registration to a mobile communication system of a Long Term Evolution (LTE) mobile communication system, or establishing, by the mobile station, radio connection with a radio access network apparatus of the LTE mobile communication system without performing the location registration; issuing a notification to the radio access network apparatus of the WCDMA mobile communication system by an exchange apparatus of the WCDMA mobile communication system upon reception of a predetermined signal, the notification implying that the mobile station performs the location registration to the LTE mobile communication system or establishes radio connection with the radio access network apparatus of the LTE mobile communication system; and releasing the resources for radio connection by the radio access network apparatus of the WCDMA mobile communication system without transmitting a signal to release the resources to the mobile station in response to the notification from the exchange apparatus of the WCDMA mobile communication system.
