Abstract:
1. A method of associating a wireless terminal, a relay apparatus, a communication management apparatus, and a bandwidth allocation management apparatus, comprising: relaying by a first relay apparatus communication between the wireless terminal and another wireless terminal; establishing by the communication management apparatus communication connections between the wireless terminal and the other wireless terminal via the first relay apparatus; managing by the bandwidth allocation management apparatus bandwidth allocation of the first relay apparatus in accordance with a bandwidth allocation request from the communication management apparatus; establishing by the wireless terminal first association with the first relay apparatus, the bandwidth allocation management apparatus, and the communication management apparatus; and when the wireless terminal moves from a receiving range of the first relay apparatus to a receiving range of a second relay apparatus, establishing by the wireless terminal second association with the second relay apparatus, the bandwidth allocation management apparatus which has been associated with the first relay apparatus, and the communication management apparatus which has been associated with the first relay apparatus, the method further comprising: sending by the wireless terminal a request for terminal registration including a communication management apparatus identifier to the second relay apparatus; sending by the second relay apparatus a first request for terminal registration of the wireless terminal to the communication management apparatus specified by the communication management apparatus identifier in response to reception of the request for terminal registration; sending by the communication management apparatus a bandwidth allocation management apparatus identifier of the bandwidth allocation management apparatus to the second relay apparatus in response to reception of the first request for terminal registration; sending by the second relay apparatus a second request for terminal registration of the wireless terminal to the bandwidth allocation management apparatus specified by the bandwidth allocation management apparatus identifier in response to reception of the bandwidth allocation management apparatus identifier; and storing by the bandwidth allocation management apparatus association between the wireless terminal and the second relay apparatus in response to reception of the second request for terminal registration.
