Abstract

When there is a call access request, channel status deciding section 105 decides as to whether the channel is saturated based on the number of users registered in user code storing section 106. If there is a call access request from a user that desires good-quality service when a channel is saturated, user code registration section 107 searches user code storing section 106 to see whether there is any low-rate user registered that holds a low-rate contract. When a low-rate user is registered, this user'"'"'s channel is cut off, and a channel for the user that has made a call access request is accessed. By this means, it is possible to satisfy every user'"'"'s need in wireless communication and make effective use of frequency resources.

Claims

1. A base station apparatus, comprising:

a channel status deciding section that makes decisions as to whether or not a channel status is saturated based on the number of currently communicating users, and

a channel access control section that, when the channel status is saturated, selects a user to allow channel access or high-speed communication based on the user'"'"'s priority.

2. The base station apparatus according to claim 1, wherein, when the channel status is saturated and there is a channel access request from a high priority user, said channel access control section cuts off a channel in respect to a low-priority user from among currently communicating users and secures a channel for the high-priority user.

3. The base station apparatus according to claim 2 wherein, upon sending a signal that requests a channel cutoff to a currently communicating low-priority user and then receiving a signal that accepts the channel cutoff from the low-priority user, said channel access control section cuts off a channel in respect to the low-priority user and secures a channel for the high priority user.

4. The base station apparatus according to claim 1 wherein, when the channel status is saturated and there is a channel access request from a high priority user, said channel access control section reduces communication speed or cuts off a channel in respect to a low-priority user currently engaged in high-speed communication and increases the high priority user'"'"'s communication speed.

5. The base station apparatus according to claim 4 wherein, upon sending a signal that requests to reduce communication speed or to cut off a channel to a low-priority user currently engaged in high-speed communication and then receiving a signal to accept low-speed communication or to cut off a channel from the low-priority user, said channel access control section reduces communication speed or cuts off a channel in respect to the low-priority user and increases the high-priority user'"'"'s communication speed.

6. A switching control apparatus that performs wireless communication with the base station apparatus according to claim 1 and that, when said base station apparatus cuts off a channel in respect to a currently communicating low-priority user and a high priority user gains access to a channel, charges special fees to the high-priority user.

7. A communication terminal apparatus that performs wireless communication with the base station apparatus according to claim 1 and implements a channel cutoff or a communication speed reduction based on an instruction from said base station apparatus.

8. A communication terminal apparatus that performs wireless communication with the base station apparatus according to claim 1 and that upon receiving a request for a channel cutoff or a communication speed reduction displays to the effect thereof and implements the channel cutoff or communication speed reduction in compliance with a instruction from a user.

9. A channel access control method whereby whether or not a channel status is saturated is decided based on the number of currently communicating users, and when the channel status is saturated and there is a channel access request from a high-priority user, a channel is cut off in respect to a low-priority user from among the currently communicating users and implements a channel access in respect to the high-priority user.

10. A channel access control method, whereby whether or not a channel status is saturated is decided based on the number of currently communicating users, and when the channel status is saturated and there is a high-speed communication request from a high-priority user, the high priority user'"'"'s communication speed is increased by cutting off a channel or reducing communication speed in respect to a low-priority user from among the currently communicating users.
