摘要:
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.

A mobile communication system 100 includes a specific cell configured to allow a specific user to be provided with a service and to allow a non-specific user other than the specific user to be provided with a limited service. The mobile communication system 100 includes a management unit 23 configured to manage a presence state of the non-specific user in the specific cell in addition to a presence state of the specific user in the specific cell.
摘要:
A UE 300 is connectable to a first radio communication system and a second radio communication system which differs from the first radio communication system and uses multiple frequency bands. The UE 300 receives RRC CONNECTION REJECT which gives an instruction to switch from the first radio communication system to the second radio communication system and an indication on multiple switching target frequencies included in the frequency bands used by the second radio communication system, and, if the multiple switching target frequencies include an unavailable frequency at which the UE 300 is incapable of transmission/reception, searches for only a cell of a switching target frequency among the multiple switching target frequencies exclusive of the unavailable frequency.
摘要:
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.
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.
