Specifically, existing WLAN resources are converted into wireless access points (APs) to create a dense infrastructure of wireless APs. To leverage this dense AP infrastructure, central management techniques are employed. With client-to-AP mapping, these techniques are used to prevent the discovery of multiple APs in a WLAN by a client device and to select a single AP (using certain policies) to associate with the client device and provide it with an enhanced wireless connection to the WLAN. Additionally, techniques are employed to centrally determine, using central policies, when the AP should disassociate from the client device and when another centrally selected AP should respond to, and associate with, the client device to provide it with an enhanced wireless connection to the WLAN—without interrupting/disrupting the client device's access. | 2008-12-25 |
20080316983 | Service information in a LAN access point that regulates network service levels provided to communication terminals - A LAN access point maintains service information that defines which of a plurality of network service levels is allocated to a plurality of communication terminals. The LAN point regulates the network service levels that it provides to the communication terminals in response to the service information. The service information may allocate different maximum communication bandwidth levels and/or allow/deny access to various network services to defined communication terminal identifiers, identifiers route locations hosted on communication terminals, and/or identifiers for users of the communication terminals. Moreover, the service information may define a time of day schedule and/or day of week schedule that varies the allocation of maximum communication bandwidth levels and/or access to various network services. | 2008-12-25 |
20080316984 | INFORMATION PROCESSING APPARTUS AND CONTROL METHOD OF AN INFORMATION PROCESSING APPARATUS - According to one embodiment, an information processing apparatus includes a radio communication unit, a searching unit which searches for an external device with which the radio communication unit is capable of performing data transfer, a detecting unit which detects all of radio communication functions provided in the external device, a monitoring unit which monitors a link speed attained with respect to the external device, a determining unit which determines whether or not the link speed acquired by the monitoring unit reaches a link speed which makes it possible to perform a radio communication function requiring the highest link speed among all of radio communication functions, and a control unit which makes a connection to the external device unit when the determining unit determines that the link speed is reached. | 2008-12-25 |
20080316985 | WLAN having load balancing based on access point loading - A network having distribution of access point loading includes access points to which mobile stations can associate themselves based upon access point beacon signal levels and loading levels for the various access points. A mobile station receives beacon signals from various access points and determines a signal strength for the received beacon signals. The mobile station also receives access point loading information from the access points. The mobile station associates with an access point based upon the access point beacon signal strengths and the access point loading information. | 2008-12-25 |
