Virtual Space Management System

A virtual space management system, comprising:

• a space management server for managing a virtual space;
• and
• a communication control server for relaying communication between the space management server and a user terminal, wherein:
• the space management server comprises:
• an event information storing unit for storing a plurality of event information items, relating to the virtual space and to be transmitted to the user terminal, in a temporary buffer in a manner that specifies a transmission order of each of the plurality of event information items;
• an event information output unit for reading out the plurality of event information items stored in the temporary buffer in order, and outputting the read event information items to the communication control server;
• and
• a buffer information change unit for changing information stored in the temporary buffer;
• the communication control server transmits the plurality of event information items output by the event information output unit to the user terminal in order;
• and
• the event information output unit varies an amount of data to be output per unit time to the communication control server according to an amount of data transmittable per unit time by the communication control server to the user terminal.

A space management server for managing a virtual space, the space management server being connected to a communication control server for relaying communication with a user terminal, and comprising:

• event information storing means for storing a plurality of event information items, relating to the virtual space and to be transmitted to the user terminal, in a temporary buffer in a manner that specifies a transmission order of each of the plurality of event information items;
• event information output means for reading out the plurality of event information items stored in the temporary buffer in order, and outputting the read event information items to the communication control server;
• and
• buffer information change means for changing information stored in the temporary buffer,
• wherein the event information output means varies an amount of data to be output per unit time to the communication control server according to an amount of data transmittable per unit time by the communication control server to the user terminal.

A control method for a space management server for managing a virtual space, the space management server being connected to a communication control server for relaying communication with a user terminal, the control method comprising:

• an event information storing step of storing a plurality of event information items, relating to the virtual space and to be transmitted to the user terminal, in a temporary buffer in a manner that specifies a transmission order of each of the plurality of event information items;
• an event information output step of reading out the plurality of event information items stored in the temporary buffer in order, and outputting the read event information items to the communication control server;
• and
• a buffer information change step of changing information stored in the temporary buffer,
• wherein, in the event information output step, an amount of data to be output per unit time to the communication control server is varied according to an amount of data transmittable per unit time by the communication control server to the user terminal.

A computer readable information recording medium, storing a program for causing a space management server for managing a virtual space, the space management server being connected to a communication control server for relaying communication with a user terminal, to function as:

• event information storing means for storing a plurality of event information items, relating to the virtual space and to be transmitted to the user terminal, in a temporary buffer in a manner that specifies a transmission order of each of the plurality of event information items;
• event information output means for reading out the plurality of event information items stored in the temporary buffer in order, and outputting the read event information items to the communication control server;
• and
• buffer information change means for changing information stored in the temporary buffer,
• wherein the event information output means varies an amount of data to be output per unit time to the communication control server according to an amount of data transmittable per unit time by the communication control server to the user terminal.
