Abstract: A handoff control method includes the following: Handoff status information of a first mobile host (MH) is collected. The handoff status information includes at least one parameter that is used for representing a status that happened during the first handoff from a source access point (AP) to a target AP. A handoff policy is generated based on the handoff status information, and used for optimizing a handoff process of an MH associated with the source AP.

A handoff control device and a system represent technical solutions that optimize the handoff process, reduce a total time delay of handoff, and increase a likelihood of successful handoff.

The second communication device receives the broadcast beacon over any one frequency hopping channel of the N frequency hopping channels to acquire the synchronization information. The second communication device exchanges information with the first communication device for access.

Accordingly, the information exchange between the base station and a more or less intelligent “identification unit” in the antenna is performed to allow identification of the antenna from the base station side and further allow diagnosis of the cable link.

Abstract: A load balancing method for a wireless communication system, which has a backbone network, more than one Access Point connected to the backbone network and more than one client. In the method, the client transmits a Probe Request message to the more than one Access Point; the Access Point monitors its load. If the Access Point is under an overload situation, it transmits a Probe Response message to the client by the minimum transmitting power. If the Access Point is under normal load situation, it transmits a Probe Response message to the client by normal transmitting power. The client preferentially chooses the Access Point under normal load situation to access based on the signal strength of the received Probe Respond message. The method thus provides the client with a priority of the Access Points, wherein the Access Point under an overload situation has a lower priority.

Abstract: A communication method in an automation system, wherein the system comprises an access point and client terminals that receive downlink data sent from the access point and send uplink data to the access point, and the data transmission is divided into a master multiple receiver aggregation phase and more than one slave multiple receiver aggregation phases. During the master multiple receiver aggregation phase, the access point aggregates the data to be sent to the plurality of client terminals into one packet for transmitting in the downlink, and during the slave multiple receiver aggregation phases, the access point aggregates data in which errors have occurred when being transmitted during the master multiple receiver aggregation phase into one packet for transmitting in the downlink. The method can have strict control, through the access point and over the uplink and downlink data transmission, thus enhancing the certainty during automation communication and further reducing the cycle time.
