BASE STATION APPARATUS, COMMUNICATION CONTROL SYSTEM, COMMUNICATION CONTROL METHOD, AND INTER-STATION CONTROL METHOD
First Claim
1. A base station apparatus comprising:
- a determining unit that determines whether a direct link has been established between the base station apparatus and another base station apparatus, when a mobile device makes a request to switch a communication recipient from the base station apparatus to the other base station apparatus;
a link information acquiring unit that acquires, indirectly from the other base station apparatus, link information necessary for establishing the direct link to the other base station apparatus, when the determining unit determines that no direct link to the other base station apparatus has been established; and
a link requesting unit that requests the other base station apparatus to establish the direct link to the base station apparatus, based on the link information of the other base station apparatus acquired by the link information acquiring unit.

7. A communication control method performed by a communication control system comprising a first base station apparatus with which a mobile device is in wireless communication;
- a second base station apparatus neighboring the first base station apparatus; and
a control device connected to the first and the second base station apparatuses, the communication control method comprising;determining whether a direct link has been established to the second base station apparatus, when the mobile device makes a request to switch a communication recipient from the first base station apparatus to the second base station apparatus; acquiring, from the second base station apparatus through the control device, link information necessary for establishing the direct link to the second base station apparatus, when, in the determining, it is determined that no direct link to the second base station apparatus has been established; and requesting the second base station apparatus to establish the direct link to the first base station apparatus, based on the link information of the second base station apparatus acquired in the acquiring.
- a second base station apparatus neighboring the first base station apparatus; and
-
8. An inter-station control method comprising:
-
determining whether a direct link has been established between a base station apparatus and another base station apparatus, when a mobile device makes a request to switch a communication recipient from the base station apparatus to the other base station apparatus; acquiring, indirectly from the other base station apparatus, link information necessary for establishing the direct link to the other base station apparatus, when, in the determining, it is determined that no direct link to the other base station apparatus has been established; and requesting the other base station apparatus to establish the direct link to the base station apparatus, based on the link information of the other base station apparatus acquired in the acquiring.
