Abstract

When a second mobile machine requests the communication of priority data with a base station while a first mobile machine conducts the communication of non-priority data with the base station, the base station transmits wait information to the first mobile machine by using a down link control channel to control the first mobile machine to the waiting state and allocates the down link control channel to the second mobile machine to control the second mobile machine to conduct the communication of the priority data. When the communication of the priority data with the second mobile machine is completed, the base station transmits communication resumption information to the waiting first mobile machine by using the down link control channel to resume the communication of the non-priority data.

Claims

1. A communication control method between a base station and first and second mobile machines when said second mobile machine requests communication of priority data with said base station while said first mobile machine conducts communication of non-priority data with said base station, comprising the steps in said base station of:

transmitting wait information to said first mobile machine by using a down link control channel to control said first mobile machine to a waiting state and allocating said down link control channel to said second mobile machine to control said second mobile machine to conduct the communication of the priority data; and

when the communication of the priority data with said second mobile machine is completed, transmitting communication resumption information to said waiting first mobile machine by using said down link control channel to resume the communication of the non-priority data.

2. A communication control method according to claim 1 wherein when said base station transmits the wait information to said first mobile machine, said base station further transmits a period for intermittently receiving said down link control channel.

3. A communication control method according to claim 2 wherein said waiting first mobile machine receives an access channel of an adjacent base station, which is adjacent to said base station, by utilizing an idle time during the intermittent reception of said down link control channel to acquire control channel idle information of said adjacent base station, and when the idle control channel of said adjacent base station is available, said first mobile machine switches from said base station to said adjacent base station.

4. A communication control method according to claim 2 wherein said waiting first mobile machine receives an access channel of an adjacent base station, which is adjacent to said base station, by utilizing an idle time during the intermittent reception of said down link control channel to acquire control channel idle information of said adjacent base station, and when the idle control channel of said adjacent base station is available, said first mobile machine switches from said base station to said adjacent base station after transmission of base station movement information to said base station which transmits the wait information.

5. A communication control method between a base station and first and second mobile machines when said second mobile machine requests communication of priority data with said base station while said first mobile machine conducts communication of non-priority data with said base station, comprising the steps in said base station of:

transmitting wait information to said first mobile machine by using a first down link control channel to control said first mobile machine to a waiting state and allocating said first down link control channel to said second mobile machine to control said second mobile machine to conduct the communication of the priority data; and

when a second down link control channel different from said first down link control channel is idle, controlling said second mobile machine to a waiting state for only one frame and transmitting slot movement information to said waiting first mobile machine to resume the communication by using said second down link control channel to resume the communication of the non-priority data.

6. A communication control method according to claim 5 wherein when said base station transmits the wait information to said first mobile machine, said base station further transmits a period for intermittently receiving said first down link control channel.

7. A communication control method according to claim 6 wherein said waiting first mobile machine receives an access channel of an adjacent base station, which is adjacent to said base station, by utilizing an idle time during the intermittent reception of said first down link control channel to acquire control channel idle information of said adjacent base station, and when the idle control channel of said adjacent base station is available, said first mobile machine switches from said base station to said adjacent base station.

8. A communication control method according to claim 6 wherein said waiting first mobile machine receives an access channel of an adjacent base station, which is adjacent to said base station, by utilizing an idle time during the intermittent reception of said first down link control channel to acquire control channel idle information of said adjacent base station, and when the idle control channel of said adjacent base station is available, said first mobile machine switches from said base station to said adjacent base station after the transmission of base station movement information to said base station which transmitted the wait information.

9. A communication control method between a base station and first and second mobile machines when said second mobile machine requests communication of priority data with said base station while said first mobile machine conducts communication of non-priority data with said base station, comprising the steps in said base station of:

transmitting wait information to said first mobile machine by using a first down link control channel to control said first mobile machine to a waiting state and allocating said first down link control channel to said second mobile machine to control said second mobile machine to conduct the communication of the priority data; and

when a second down link control channel different from said first down link control channel is idle, transmitting slot movement information to said waiting first mobile machine by using said first down link control channel;

wherein when said waiting first mobile machine receives the slot movement information, said first mobile machine resumes the communication of the non-priority data in a next frame by using said second down link control channel.

10. A communication control method according to claim 9 wherein when said base station transmits the wait information to said first mobile machine, said base station further transmits a period for intermittently receiving said first down link control channel.

11. A communication control method according to claim 10 wherein said waiting first mobile machine receives an access channel of an adjacent base station, which is adjacent to said base station, by utilizing an idle time during the intermittent reception of said first down link control channel to acquire control channel idle information of said adjacent base station, and when the idle control channel of said adjacent base station is available, said first mobile machine switches from said base station to said adjacent base station.

12. A communication control method according to claim 10 wherein said waiting first mobile machine receives an access channel of an adjacent base station, which is adjacent to said base station, by utilizing an idle time during the intermittent reception of said first down link control channel to acquire control channel idle information of said adjacent base station, and when the idle control channel of said adjacent base station is available, said first mobile machine switches from said base station to said adjacent base station after transmission of base station movement information to said base station which transmitted the wait information.
