Abstract: PURPOSE:To dynamically secure a message area for inter-task communication even for interruption processing routine by securing beforehand the message area by using the memory controlling function of basic software by a receiving task part, and transmitting a message to the receiving task part by using the secured message area by the operation of an interruption processing part. CONSTITUTION:When the receiving task part 12 acquires a message area pool 14 from a memory pool controlled by the basic software by a message area pool generating means 121, and receives the message from a message queue 11, it returns the message area, and simultaneously, it replenishes another message area by a message area replenishing means 124. The interruption processing part 10 acquires the message area generated by the receiving task part 12 by a message area acquiring means 101, and transmits the message by a message transmitting means 102, and performs communication between the interruption processing part 10 and the receiving task part 12. Thus, the dynamic security of the message area becomes possible for the interruption processing routine.

Abstract: PURPOSE:To easily read a change in the reproduction elapsed time even when one mail time is varied by adjusting the increment of an indicator so that the time unit for update is made nearly constant independently of the length of a mail. CONSTITUTION:A terminal equipment 10 and a multi-media mail system 20 are connected via an exchange 5 through a data line BCH and a control information line DCH respectively. The terminal equipment 10 consists of a data transfer buffer 11, control information buffer 12, a CPU 13, a display device 14 and a memory 15, and the display device 14 includes an indicator 14a displaying the reproduction elapsed time. The increment of the indicator 14a is adjusted so that the update time unit is made nearly constant independently of the length of a mail and the data is set to the display device 14. Thus, even if one mail time is varied, the change in the reproduction elapsed time is easily read.

Abstract: PURPOSE:To efficiently reserve a mail in a file even when the size of an envelope/content header is different at every mail by storing an envelope/content header at every mail into a secondary storage device as an independent file similar to the mail main body. CONSTITUTION:All mails existing in the system are stored respectively in the secondary storage device 13 while being divided into an envelope/content header ENV 17 and a main text MAL 18 respectively, and managed via a hierarchical directory 14 by a file management section 12. The hierarchical directory 14 gives the correspondence of the message transfer part MTA being the system structure unit, an interface section UA, a mail number and main ENV, MAL file. Thus, the mail management file MNG is constituted as a fixed data length and efficient memory resource is attained.

Abstract: PURPOSE:To transfer execution right from a higher privileged level to a lower privileged level by artificially performing command CALL execution procedures by a stack contents setting means and performing execution right transfer procedures by a command IRET. CONSTITUTION:Application 7 uses a command CALL to request the read of a file, which is stored on a floppy 20, to a fundamental software OS kernel 10. The kernel 10 analyzes it to judge that file management 6 should read this file. The kernel 10 sets three parameters to a parameter delivery buffer 5 and transfers the execution right to management 6. Management 6 receives parameters from the buffer 5 and reads out data corresponding to a designated side of the designated file from the floppy 20 to a buffer memory 30 and returns the control to the kernel 10. A command IRET start part 2 in the kernel 10 issues a command to restart execution of application 7. Thus, the execution right is transferred from a higher privileged level to a lower privileged level.

Abstract: PURPOSE:To shorten a retrieval time, and to quickly process the same class mail service for the person of the same level class. i.e., for the person of the same title by storing a pointer, which can be linked to the user information of the lateral direction of, at least, the same level class, in the user information. CONSTITUTION:When a multiple address communication request for all chiefs of a section is issued, a retrieving part 6 accesses a memory 5, in which the data base of the user information is stored, and it retrieves successively from the president of the first level class, according to a tree structure, down to the senior managing director of the second level class and the chief of a division of the third level class. When the retrieval comes down to the fourth level class, the objective chief of a section is retrieved. Hereafter, the retrieval is carried out along the pointer, to be linked to the same level class user information and prepared in the user information, and the user information of all the chiefs of a section, on the same line, i.e., arranged at the same level, is read out from the memory 5, and the information such as the names of all the chiefs of a section or the like is transferred to an address memory 7. Next, the address and the destination of the respective chief of a section, read out successively from the address memory 7 are added to the same message sentence, read out from a message memory 8, by a composing part 9, and transmitted from the composing part 9.

Abstract: PURPOSE:To enable the service control of a more delicate message at the time of a voice mail service by searching a message table through the present time and the subscriber number of an opposite terminal, and transmitting a took out message to the opposite terminal. CONSTITUTION:A message data base is prepared in a memory 6 inside an exchange corresponding to a terminal, and the time and a message corresponding to the opposite terminal are registered. When an incoming request is detected, a call processing program (provided in a central controlling part 4) decides an incoming terminal, and if an absence is certified, the message table of the incoming terminal is accessed by a voice service device 5a, and the message is called out and sent to the opposite terminal. Thus, a subscriber prepares the message table containing the message corresponding to the time and the opposite terminal, and at the time of the voice mail service, the more delicate message related to the terminal of an absent time can be sent to the opposite terminal corresponding to the time and the opposite terminal.

Abstract: PURPOSE:To arrange and consolidate a vacant area with a few transfer quantity, by extracting a data storage and usage area that is almost equal to the vacant area, and transferring the content of the area to the vacant area. CONSTITUTION:A vacant area retrieving part 9 extracts the first entry on a vacant area list 7. When two or more entries exist on the list 7, an in-use area retrieving part 11 extracts a usage area that is equal to, or smaller than an extracted vacant area. When a prescribed usage area is not found, a moving area deciding part 12 extracts the data storage and usage area positioned just after the vacant area. Next, an area moving part 13 transfers the content of the area extracted at the retrieving part 11, or the deciding part 12, to the said vacant area. By registering a result on the list 7 at a new vacant area registering part 14, and releasing it on the list 7 by an old vacant area releasing part 15, it is possible to arrange and consolidate the vacant area with a few transfer quantity.

Abstract: PURPOSE:To manage quickly unused areas of a direct access storage device (DASD) by distributing space management information of the DASD onto a main storage and the DASD to reduce the number of times of access to the DASD for reference to space management information. CONSTITUTION:When areas on auxiliary storages 3 and 4 are assigned to and released from users repeatedly, used areas and unused areas exist together. A space reference list 6 is the management table of unused areas and is stored in auxiliary storages 3 and 4, and this table is read out from auxiliary storages and is loaded to a main storage device 2 and is updated by a CPU 1 when a space is assigned or released. According as the number of unused spaces is increased, the number of terms of the list 6 is increased and the overhead due to the search time and the load time is extended. Therefore, the list 6 is divided into units of a certain number of terms (for example, 100 terms), and a reference list management table 7 for them is arranged in the main storage device 2. A pertinent unit is determined by this table 7 and contents of this unit are searched, thus reducing the number of terms to be searched.

Abstract: PURPOSE:To prevent the increase of scale in call processing program and also to facilitate the easy change in program such as addition, deletion, etc., by setting the state (e.g., busy, all) of an upper call and deciding a task according to the upper call state, an input event and a task decision table. CONSTITUTION:In case such a task that has the common state of each call to a specific input event type is designated, the state of a high-order call representing the states of calls is set instead of a case where an input event is set at the state of each call. Then a task is decided. For this purpose, a task decision table 22a is provided to a main memory 22 of a high performance terminal 2. Then a call state table 220 of the table 22a stores states 809 all, 907 busy and 908 all of an high-order call in addition to each call state. While an event type-based table 221 stores the input event types (incoming request, data information request, etc.) for execution of a common task. Furthermore a service counter table 222 stores the task names (transfer service, store service, data information service, etc.) which should be executed according to the stored input event types.

Abstract: PURPOSE:To reduce the amount of program development, and reduce the scale of a program and simplify control by controlling call processing control memory while separating the state of a service requesting person and states of other subscribers. CONSTITUTION:When a subscriber A originates, the system assigns the call processing control memory CCB and a service control part 12 starts the program of a proposer control part 14 once the subscriber A requests a conference service. The subscriber A when allowing a subscriber B to join in the conference sends a request to start a participant control part 15 from the control part 14 and assigns call processing control memory for controlling the subscriber B, and the control part 15 control the subscriber B. When a subscriber C is permitted to join, operation is performed similarly. Thus, the control part 15 operates on multiple basis for every paarticipant, so the efficiency of a static step is improved.
