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.

Abstract: 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.

Abstract: 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.

Abstract: A polling system for voting, auction bidding, opinion surveying, and the like, communicable with mobile communications devices for performing information collection responsive to input from the mobile communications devices, utilizing an existing short message service (SMS) and/or Internet wireless applications protocol (WAP), and information processing means for processing and analyzing the information collected. The information so collected is stored, organized, analyzed, transmitted to the mobile communication devices using SMS, or through the Internet using WAP, or to Internet-connected devices of any kind. The polling results can be transmitted and graphically displayed in a smooth integration with existing presentation tools such as PowerPoint™ thereby achieving instantaneous polling results for pollsters, feedback to respondents, and visual display for mass media presentations.

Abstract: A system and method is provided for retrieving information on a network and displaying the information on a personal computer or other visual display device. A proxy multiplexor opens connections with each of a plurality of service providers and exchanges authentication information such as a user ID and password with each of the service providers by retrieving and forwarding cookies containing the authentication information. Updated status data from the service providers is displayed within icons representing each of the service providers.

Abstract: 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.

Abstract: 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.
