摘要:
The invention provides an authentication, authorization and accounting (AAA) a system and method for a plurality of wireless local area networks (WLANs) operated by a plurality of WLAN operators comprising a mobile communications device connecting to a terminal comprising an Internet access application program for accessing the Internet, a personal identification number (PIN) application program, and a unique identifier application program. An Internet access session is requested from the mobile device by activating the Internet access application program in the terminal. Entry of a PIN is requested by activating the PIN application program in the terminal, wherein the PIN is authenticated. If the PIN is authenticated, a unique identifier is retrieved from the mobile device by activating the unique identifier application program in the terminal wherein the unique identifier is accepted by all of the plurality of WLANs operated by the WLAN operators, wherein the unique identifier is sent to an authentication server for WLAN authentication. If the authentication server authenticates the unique identifier, the authentication server instructs an access server that the unique identifier has been authenticated wherein the access server instructs an accounting server to begin access fee calculation. If the access server determines that the Internet access session has ended, the access fee calculation is ended at the accounting server and a total fee is calculated from the ended access fee calculation.

The invention advantageously provides a mobile common service platform and software in telecommunications systems. A common service platform (CSP) according to the invention is an integrated platform that supports both wireless and landline mobile services and business transactions. A CSP system according to the invention includes a common service platform or CSP for integrating a plurality of applications into a single platform for multiple uses in a plurality of communications systems. The CSP is connected with the plurality of applications and a plurality of users. Multiple users in different communications systems having varied communications protocols can utilize generally the same application (as selected by the users) through the CSP. Requests for uses in different communications system are transferred to the CSP for conversion into generally the same format that is acceptable by a selected application. Outputs from the selected application are transferred into formats that are acceptable by the requesting user. The CSP system advantageously enables a communications system to be quickly offered to market in conjunction with value-added services through applications rendered by third party service providers.

The invention advantageously provides an alert system and method for geographic or natural disasters that utilize a telecommunications network for monitoring geographic data in disaster-prone areas and accordingly issuing warnings against potential disasters to people inside the monitored area. An alert system according to a preferred embodiment of the invention comprises a telecommunications service network, one or more wireless sensor modules and a control center. The telecommunications network according to this particular embodiment includes service coverage over the monitored areas. The wireless sensor modules are installed to selected locations inside monitored areas. Each of the sensor modules further comprises at least one sensor for collecting geographic or geodetic data and a wireless communications unit for sending collected geographic data to the control center via the telecommunications network. The control center then receives and processes the monitored geographic or geodetic data sent by the wireless sensor modules for further algorithmic analysis. The control center accordingly issues alerts for imminent geographic or natural disasters if the processing of the geographic or geodetic data produces adverse results.

The present invention presents a system and method of providing information retrieved from a server from across a communication network that enables archiving services that do not interfere with existing components and protocols. The services enable users to retrieve and/or search for old information, even after such information has evolved or disappeared from the original server. The network resource naming (e.g. URL) format is extended to include archive directives that are intercepted and performed by a proxy server. The proxy interprets the archive directive and executes the specified archival command: e.g., adding the information to a storage repository, searching and retrieving the information from the storage repository, scheduling automatic archiving of specified server information, transparent archiving of information that is accessed by the client or of the client's cache. The information can be easily indexed by a timestamp. Multiple proxy servers can collaborate permitting information to be archived in a distributed fashion. Embodiments of the present invention advantageously do not require changes to client or server software or communication protocols.

A mobile device server includes a flexible architecture having a plurality of components for allowing various mobile devices and protocols to communicate with each other and to receive data from various information spaces. Interface devlets send and receive messages in respective protocols. Access infolets utilize respective access methods to provide an abstract view of various information spaces. Logic applets implement service and/or application logic by processing information from one or more infolets. A further component referred to as a let engine communicates with the devlets, infolets, and applets, and maintains user and device profile information to provide a flexible framework for the mobile device server that can readily support new devices and protocols.
摘要:
A method and a system in which a computing system transparently accesses resources connected to the Internet. A memory of the computing system contains an operating system, a cache associated with the operating system, a shared library and an access server. The shared library is responsive to a system call for a file by determining whether a path name for the file is located under a personal name space in the memory and by issuing a request for retrieving the file from an Internet resource based on the path name located under the personal name space when the file is not stored in the cache and has a path name located under the personal name space An access server, in response to the request from the shared library, selects an appropriate access protocol for retrieving the file from the Internet resource and retrieves the file from the Internet resource. The shared library then issues the system call to the operating system when the access server retrieves the file. The access server restores the file to the Internet resource when the application closes the file.

Techniques for providing replicated files in a distributed system. A replicated file has a set of copies in components of the distributed system. Operations on the copies have the same semantics for the application processes accessing them as operations on a single copy of a file in a system where all processes execute on the same host. These semantics are achieved by means of a distributed synchronization system. Each replicated file has a read token and a write token. In order for an application process to perform an operation on a replicated file, the token required for the operation must be in the process's host and the process must have access to the token. Tokens are passed between hosts by token servers which respond to requests for tokens from application processes and from other token servers. The techniques are implemented using a library which replaces a standard I/O library, and may thus be employed without modification to hardware or the operating system.
