MOBILE COMMUNICATIONS SYSTEM, MOBILE STATION DEVICE, BASE STATION DEVICE AND CHANNEL ALLOCATION METHOD
First Claim
1. A mobile communications system, comprising:
- a base station device; and
a plurality of mobile station devices,wherein the base station device comprises channel allocating means for determining, among a plurality of traffic channels, at least some of the traffic channels allocated to each of the mobile station devices, and gives notice of allocated channel information indicative of the traffic channels determined by the channel allocating means to the each of the mobile station devices,wherein the each of the mobile station devices performs communication with the base station device via the traffic channels indicated by the allocated channel information,wherein the each of the mobile station devices comprises;
channel allocation refusal determining means for determining a traffic channel refused to be allocated from the base station device among the plurality of traffic channels based on information indicative of a state of communication with the base station device; and
refused channel information notice means for giving notice of refused channel information indicative of the traffic channel refused to be allocated from the base station device among the plurality of traffic channels to the base station device, andwherein the channel allocating means determines whether or not the traffic channels allocated to the each of the mobile station devices are changed, based on the refused channel information noticed from the each of the mobile station devices and the allocated channel information noticed to the each of the mobile station devices.

Abstract
Each mobile station device (12) includes: a subchannel allocation refusal determining section (50), which determines a subchannel refused to be allocated from a base station device (10), based on a communication quality measured for each subchannel by a communication quality measuring section (44); an RMAP creating section (52), which creates refused channel information (RMAP information) indicating the subchannel determined to be refused to be allocated; and a transmitting section (54) which gives notice of the created RMAP information to the base station device (10). The base station device (10) includes: an RMAP acquiring section (26), which acquires the RMAP information noticed from the each mobile station device (12); and a subchannel allocating section (32), which determines whether to change a subchannel to be allocated to the each mobile station device (12), based on the acquired RMAP information and allocated channel information (MAP information) indicating the subchannel allocated to the each mobile station device (12).

4. A mobile station device that communicates with a base station device via, among a plurality of traffic channels, at least some of the traffic channels noticed from the base station device, the mobile station device comprising:
-
channel allocation refusal determining means for determining a traffic channel refused to be allocated from the base station device among the plurality of traffic channels based on information indicative of a state of communication with the base station device; and refused channel information notice means for giving notice of refused channel information indicative of the traffic channel refused to be allocated from the base station device among the plurality of traffic channels to the base station device.

5. A base station device comprising channel allocating means for determining, among a plurality of traffic channels, at least some of the traffic channels allocated to each of a plurality of mobile station devices, and giving notice of allocated channel information indicative of the traffic channels determined by the channel allocating means to the each of the mobile station devices,
wherein the channel allocating means determines whether or not the traffic channels allocated to the each of the mobile station devices are changed, based on refused channel information indicative of a traffic channel refused to be allocated by the each of the mobile station devices among the plurality of traffic channels noticed from the each of the mobile station devices, and the allocated channel information noticed to the each of the mobile station devices.

6. A channel allocation method for a mobile communications system, comprising:
-
a channel allocating step of determining, among a plurality of traffic channels, at least some of the traffic channels allocated to each of a plurality of mobile station devices, and giving notice of allocated channel information indicative of the traffic channels determined in the channel allocating step to the each of the mobile station devices, communicating, by each of the mobile station devices, with a base station device via the traffic channels indicated by the allocated channel information, wherein the each of the mobile station devices performs; a channel allocation refusal determining step of determining a traffic channel refused to be allocated from the base station device among the plurality of traffic channels based on information indicative of a state of communication with the base station device; and a refused channel information notice step of giving notice of refused channel information indicative of the traffic channel refused to be allocated from the base station device among the plurality of traffic channels to the base station device, wherein the channel allocating step determines whether or not the traffic channels allocated to the each of the mobile station devices are changed, based on the refused channel information noticed from the each of the mobile station devices and the allocated channel information noticed to the each of the mobile station devices.
