摘要： A wireless Local Area Network (LAN 11) capable of providing “enterprise guest” hosting includes at least one an e-open wireless LAN access point (15) that provides access to both guests and local users. Upon receipt of a request for access, the access point forwards the request to an authentication proxy. The authentication proxy then authenticates the party requesting access in accordance with that party's status (that is, whether the party is a local user or guest). Upon successful authentication, the network routes the traffic from a local user differently as compared to that for a guest. For example traffic from guests goes to gateway for receipt in an external network such as the Internet, whereas traffic from the local user goes to a local network, e.g., a corporate intranet. In this way, the Wireless LAN 11, after ascertaining the status of the party requesting access, can limit guest traffic according to the guest access policy.

摘要： A method for downloading and displaying a video program using a mobile terminal that includes a first radio access network having a first data transfer rate and a second radio access network having a second data transfer rate faster than the first data transfer rate. The downloaded video program is displayed at a predetermined playback rate. Excess portions of the downloaded video program that result when a rate at which the video program is downloaded exceeds the predetermined playback rate are buffered. A third data transfer rate that is lower than the first transfer rate is calculated in response to the predetermined playback rate, the buffered excess portions and the time duration of the remainder of the video program. The third data transfer rate is negotiated with the first network for downloading the video program when the difference between the first and third data transfer rates exceeds a threshold level.

摘要： A method for enabling an access device to securely access content from at least a content provider and prevent a cloned access device from accessing such content. During registration of the access device with the content provider, the access device requests from a designated certificate authority a certificate having a public key of the content provider therein. Upon authentication of the certificate, the access device generates a key and uses the public key to exchange the key with the content provider. The key is then used for subsequent secure communications between the access device and the content provider. In this manner, a cloned device does not have access to the key and is unable to download content from the content provider.

摘要： A portable communications device advantageously can access an enterprise network through a Virtual Private Network link without the need for a VPN client. To accomplish communications, the portable communications device establishes a communication link with a wireless access point using one or several well-known secure wireless protocols. The wireless access point establishes a communication link with the enterprise network through the VPN and bridges the connections to afford an end-to-end link between the portable computing device and the enterprise network.

摘要： A wireless Local Area Network (LAN 11) capable of providing “enterprise guest” hosting includes at least one an e-open wireless LAN access point (15) that provides access to both guests and local users. Upon receipt of a request for access, the access point forwards the request to an authentication proxy. The authentication proxy then authenticates the party requesting access in accordance with that party's status (that is, whether the party is a local user or guest). Upon successful authentication, the network routes the traffic from a local user differently as compared to that for a guest. For example traffic from guests goes to gateway for receipt in an external network such as the Internet, whereas traffic from the local user goes to a local network, e.g., a corporate intranet. In this way, the Wireless LAN 11, after ascertaining the status of the party requesting access, can limit guest traffic according to the guest access policy.
