Problems solved by technology

[0004] However, in the conventional mobile communication system, there is a problem that when a radio base station for a home cell that manages a specific home cell transmits notification information including transmission permission information restricting radio signal transmission to all mobile stations, even if the Even registered mobile stations cannot access the wireless base station for the home cell
[0007] Therefore, in places such as roads with heavy traffic or densely populated areas, a large number of wireless signals for performing location registration processing or signal transmission processing may be transmitted by non-registered mobile stations, and there is a processing load in the wireless base station for home cells. Problems that can significantly increase

change example 1

[0090] In the above-mentioned embodiments, a mobile communication system based on W-CDMA is described as an example, but the present invention is not limited to the above-mentioned mobile communication system, and can also be applied to a mobile communication system based on LTE (Long Term Evolution), for example.

[0091] In this case, the functions of the network device 10 described above are installed in at least one of the radio base station eNB or the switching center MME. That is, in the mobile communication system according to Modification 1, at least one of the radio base station eNB and the switching center MME functions as the above-mentioned network device 10 .

change example 2

[0093] refer to Figure 10 A mobile communication system according to Modification 2 of the present invention will be described. Hereinafter, a mobile communication system according to Modification 2 of the present invention will be described focusing on differences from the mobile communication system according to the above-mentioned first embodiment.

[0094] Such as Figure 10 As shown, the mobile communication system according to Modification 2 of the present invention may be a W-CDMA mobile communication system or an LTE mobile communication system.

[0095] In addition, in the mobile communication system according to Modification 2 of the present invention, the radio base station #A for the macro cell is connected to the switching center MME or the radio control device RNC, and the radio base stations #a and #b for the home cell are connected to the concentration devices HNB-GW, The switching center MME or the radio control unit RNC is connected.

[0099] Hereinafter, a mobile communication system according to Modification 2 of the present invention will be described focusing on differences from the mobile communication system according to the above-mentioned first embodiment.

[0100] In the mobile communication system according to Modification 3 of the present invention, the transmission permission information may be a signal indicating whether or not to transmit a radio signal to each cell under the jurisdiction of the radio base station.

[0101] Here, even if the mobile station UE restricts the transmission of radio signals to the first cell under the jurisdiction of the first radio base station by the received transmission permission information, based on the access information notified from the network (notified information from the radio base station) etc.) and in the process of judging whether it is necessary to send radio signals through the access information managed inside the mobile station UE, if it is judge...

Abstract

Provided is a mobile communication method including: a step in which a first radio base station #a transmits report information containing transmission enabled / disabled information indicating whether a radio signal can be transmitted; and a step which judges whether the radio signal can be transmitted according to the transmission enabled / disabled information contained in the report information and access information managed in a mobile station #X. The mobile station #X can transmit the radio signal to the first radio base station #a when an access to the first radio base station #a is allowed in the access information even if transmission of the radio signal to the first radio base station #a is regulated by the transmission enabled / disabled information.

Description

technical field [0001] The present invention relates to a mobile communication method and a mobile station. Background technique [0002] In a conventional mobile communication system, a radio base station that manages a specific cell can control restrictions on transmission of radio signals (for example, RACH signals) to mobile stations by transmitting broadcast information including transmission permission information. [0003] On the other hand, a radio base station for a home cell (Femto BTS) allows access only from mobile stations (registered mobile stations) that are granted access rights, and rejects access from mobile stations that are not granted access rights (non-registered mobile stations). enter. [0004] However, in the conventional mobile communication system, there is a problem that when a radio base station for a home cell that manages a specific home cell transmits notification information including transmission permission information restricting radio sig...
