摘要： A method of Authentication Authorization and Accounting (AAA) in an interworking between first and second networks that do not belong in the same asministrative domain, using certificate based transactions. In the method according to the invention, the second network sends a public key to the first network, and a certificate to a mobile device. The certificate includes information regarding the subscription level of the mobile device and is signed with a private key of the second network. Upon detection of the first network the mobile device transmits the certificate and the first network authenticates the certificate using the public and private keys of the second network, and authorizes access to the network in response. The first network then sends a session key encrypted with a public key of the mobile device. The mobile device decrypts the session key with a private key and access the first network using the session key. In this manner, interworking is implemented without requiring the deployment of a special interworking function to bridge between the two different types of networks.

摘要： The method for providing micro-billing for internet services includes establishing a micro-billing agent (MBA) within a user's access point (i.e., Internet Service Provider—ISP). The MBA contains the user's billing information and keeps that information exclusive to the MBA. By retaining the user's information with their access point, the user can conduct more secure online transactions, particularly for low cost transactions, without the inconvenience of inputting or transferring personal purchasing information to the online store. According to one aspect, the purchase page may be previously encoded with a micro-billing option which would enable the MBA to obtain user authorizations in online transactions in a more streamlined and secure manner.

摘要： Public wireless communications will increasingly extend into wireless LAN (WLAN) environments in order to meet the ubiquitous access, high data rate, and local services demands of future Internet appliances. By relying on IP-level services mechanisms, the Public Access Mobility LAN (PAMLAN) can simultaneously support different air interfaces, franchises for multiple services providers, and a multi-segment LAN environment including handoffs. The PAMLAN supports virtual operator LANs representing different network services providers, authorization and accounting mechanism, support of multiple air interfaces, and local IP mobility. A router associated with each base station realizes this highly distributed IP networking environment, and a QoS-enabled switched Ethernet core supports virtual networks and QoS services.

摘要： There is provided a method for managing the downloading and display of a video program using a mobile device in an networking environment that includes a first radio access network and a second radio access network that has a faster transfer rate than the first network. A layer of video program that has been encoded into multiple layers is downloaded via the first or second network. The downloaded video program is displayed at a playback rate that corresponds to a display quality. Excess portion of the downloaded video program that result when a rate at which the video program is displayed are buffered. The number of layers being downloaded and the playback rate at which the video program is displayed are increased to increase the display quality, when the buffered excess portions exceeds a threshold level.

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.
