Abstract: THIS INVENTION ALLOWS CUSTOMERS AND OTHER USERS OF THE PUBLIC SWITCHED TELEPHONE NETWORK (PSTN) TO ENABLE, DISABLE OR MODIFY SPECIAL SERVICES PROVIDED BY THE NETWORK (32). THE PSTN IS DEFINED HERE AS ALL EQUIPMENT WORLD WIDE (LAND-BASED, RADIO OR OTHER) ENABLING ORDINARY TELEPHONE USERS TO CONNECT TO OTHER TELEPHONE USERS, BUT EXCLUDES PRIVATE TELEPHONE NETWORKS SUCH AS "TIE LINE" SYSTEMS MAINTAINED OR LEASED BY PRIVATE ENTERPRISES. PRESENTLY CONTEMPLATED ACTIONS CAN BE TAKEN INDEPENDENT OF THE STATE OF THE CUSTOMER''S TELEPHONE (40) LINE (E.G. ON-HOOK OR OFF-HOOK), AND USUALLY USE OF EQUIPMENT OTHER THAN TELEPHONES AND COMMUNICATION NETWORKS (32) OTHER THAN THE PSTN (E.G. COMPUTERS OPERATING THROUGH THE INTERNET PAGERS OPERATING THROUGH PAGER NETWORKS). THE SPECIAL SERVICES INCLUDES EXISTING SERVICES (CALL WAITING, CALL BLOCKING, CALL FORWARDING, ETC.) AND NEW ONES (E.G. TRANSFERRING AN ACTIVE CALL FROM A DESK PHONE TO A MOBILE CELLULAR ONE WITHOUT INTERRUPTING THE CALL). SECURITY FIREWALLS, BETWEEN THE PUBLIC AND TELEPHONY APPLICATION INTELLIGENCE (TAI) SYSTEMS THAT ADMINISTER CUSTOMER SERVICES WITHIN THE PSTN, ENSURE THAT ACTIONS BY UNAUTHORIZED INDIVIDUALS DO NOT INTERFERE WITH OR ADVERSELY AFFECT TELEPHONE SYSTEM OPERATIONS. AUTHORIZED CUSTOMERS TAKING PRESENTLY CONTEMPLATED ACTIONS WILL NOT BE ABLE TO ADVERSELY AFFECT TELEPHONE SYSTEM OPERATIONS. THE PRESENT SYSTEM WILL WORK ON INFORMATION MAINTAINED AT ANY LEVEL OF AN INTELLIGENT NETWORK HIERARCHY WITHIN THE PSTN, INCLUDING SERVICE NODES THROUGH WHICH CUSTOMER SERVICES ARE TRADITIONALLY PROVIDED.(FIG. 8)

Abstract: A system and method for Video-on-Demand (VOD) satisfying the desire of 'surfers'. The process entails a server operating in a standard NVOD mode, w hereby it continuously sends multiple copies of each program on separate channels. Eachcopy is delayed by a staggered time interval. The in vention provides a way to fulfill a VOD user request asynchronous with the start of a NVOD transmission but wh ich still makes primary use of the NVOD transmission for that requestor. The sys tem and method combines independent server service satisfying an asynchronous reques t for only a short duration, usually less than or equal to the NVOD staggered time interval, and then aligns that requestor with an immediately previously commenced NVOD transmission.

Abstract: A program authorization mechanism for authorizing access to an address space in the main memory of a computer system by a program being run under a multiple address space facility. An access-list entry is associated with each address space, each access-list entry being designated by an access-list-entry token contained in an access register. Each access-list entry includes a private indicator which indicates if the associated address space can be accessed by all programs from this access-list entry or if the associatd address space can only be accessed by an authorized program. For a program to be authorized, an extended authorization index in a control register must match an access-list extended authorization index in the access-list entry, or the extended authorization index value must be authorized in an authority table associated with the address space. An instruction for testing a given extended authorization index for a given access-list-entry is also disclosed.

Abstract: A system, method and apparatus for Video-on-demand (VOD) satisfying the desire of 'surfers'. The process entails a server operating in a standard Near-Video-on-demand (NVOD) mode, whereby it repeatedly transmits multiple copies of each program on separate channels. Each copy is delayed by a staggered time interval. The server also repeatedly transmits a beginning portion of each NVOD program of a duration up to the staggered time interval. The invention provides a way to fulfill a VOD user requests asynchronous with the start of a NVOD transmission but which still makes primary use of the NVOD transmission for that requestor. The invention further advantageously provides fixed asset utilization in a predictable manner.

Abstract: A method and apparatus is provided to translate the contents of access registers into information for use in performing addressing functions for multiple virtual address spaces. The access registers represent the full addressing capability of the system but do not directly contain the addressing information. The system has a plurality of general purpose registers (20), a plurality of access registers (22) associated with the general registers, an access list (24,25) having access list entries which is addressed by the contents of the access register, memory storage (30) for holding address space number second table entries (ASTE) (98), where the contents of the access list entry locate the ASTE and where the ASTE contains the addressing information needed to locate a virtual address when combined with the contents of a general register. Access register translation (ART) consists of the process of determining addressing information by using the access list entry and the ASTE. The system has available to it at any one time a selection of one of two domains each represented by an access list. One domain is related to the dispatchable unit task to be performed and the other is related to the address space in which a particular program operates. The ART process selects the domain which the access register is using.
