Abstract: A multimedia-on-demand peer-to-peer device acting as a receiving peer includes a local cache memory device adapted to store a multimedia prefix. Local storage of the multimedia prefix allows rapid commencement of playback of the requested multimedia program without substantially loading the streaming capacity of an associated server device. The storage of multimedia prefixes in local cache memory of the receiving peer device can take place during periods of relatively low network loading so as to optimize network and server scheduling. Included is a method and apparatus for performing admission control in a peer-to-peer multimedia-on-demand system. The admission control system determines if there is sufficient system capacity to support a new request from a peer-to-peer device acting as a client in light of the presence of stored multimedia prefixes at the peer-to-peer device acting as a receiving peer device, among other factors.

Abstract: An access arrangement (11) provides secure access by at least one mobile communications device (121–123) by first authenticating the device itself, and thereafter authenticating the traffic therefrom. To authenticate the traffic from the mobile communications device, an authentication server (24) associated with the access arrangement (11) establishes a Wired Equivalent Privacy (WEP) encryption key for both the access arrangement and the mobile communications device. The authentication server provides the WEP encryption key to the device in connection with a command to cause the device to execute a resident ActiveX control to encrypt traffic with the WEP encryption key. Utilizing the Active X control within the mobile communications device to encrypt traffic with the WEP encryption key provides a simple, easy-to-implement method to achieve secure access.

Abstract: A key synchronization mechanism for wireless LANs is provided where the access point (AP) does not start using a new encryption key until the first data frame correctly encrypted with the new key is received from the station (STA). The new key is used from this point on, until the expiration of a key refresh interval.

Abstract: Within a radio access network (111, 112) an access point (181, 182, 183 and 184) selects a channel by first randomly choosing a channel from those available for use. The Access Point then monitors the channel for a random interval to determine if the channel is presently carrying traffic. The Access Point will select the channel unless the channel is in use by another AP. If so, then the AP will select another channel and commence monitoring for a random interval in order to determine whether the channel is available. The AP will continue to choose channels until a suitable channel is found, or all available channels have been exhausted.
