Abstract: A management server issues a game link identifier associated with friend network identification information corresponding to an inviting game and sends the game link identifier to a terminal apparatus corresponding to the friend network identification information. In the terminal apparatus, the game link identifier is passed from the inviting game to an invited game, and the program of the invited game sends the passed game link identifier and identification information of an inviting user, corresponding to the invited game, to the management server. The management server searches already issued game link identifiers, and, when a game link identifier that matches the received game link identifier is found, associates friend network identification information corresponding to the invited game associated with the received game link identifier, with the friend network identification information corresponding to the inviting game associated with the issued game link identifier.

Abstract: A terminal apparatus includes an inquiry unit that sends an inquiry, from a game used in the terminal apparatus among at least two games provided by an application system, about an invitation to another game, to an invitation information management unit of a management apparatus; an invitation information receiving unit that receives invitation information corresponding to the inquiry; and a display control unit that displays, on a display unit, details of the invitation according to the invitation information.

Abstract: A management server issues a token associated with friend network identification information identifying a user of a game provided by an application server, to the application server; receives the token passed from the game to another game on the basis of an operation of the user in a terminal apparatus where the game and the other game are available, from an application server that provides the other game; and manages, in association with each other, the friend network identification information related to the game and friend network identification information related to the other game for which the issued token matches the received token.

Abstract: A management server issues a token associated with friend network identification information identifying a user of a game provided by an application server, to the application server; receives the token passed from the game to another game on the basis of an operation of the user in a terminal apparatus where the game and the other game are available, from an application server that provides the other game; and manages, in association with each other, the friend network identification information related to the game and friend network identification information related to the other game for which the issued token matches the received token.

Abstract: A management server issues a token associated with friend network identification information identifying a user of a game provided by an application server, to the application server; receives the token passed from the game to another game on the basis of an operation of the user in a terminal apparatus where the game and the other game are available, from an application server that provides the other game; and manages, in association with each other, the friend network identification information related to the game and friend network identification information related to the other game for which the issued token matches the received token.

Abstract: If a management server receives an invitation request, the management server acquires a requester's reference identification information corresponding to a requester's user identification information, a receiver's reference identification information corresponding to a receiver's user identification information, and an identification information, by referring to a user information table. The management server generates a record in which a status information is set to “pending”, and records the record in an invitation table. Assuming that the game to which a user A wants to invite another user B is a game b, the other user B who builds a friendship with the user A in a game c, the user A manages one terminal device, and the other user B manages another terminal device. In this case, the management server sends an invitation mail indicating that there is an invitation from the user A in the game b to the other terminal device.

Abstract: A management server is provided with an accepting unit for accepting identification information identifying an application, a specifying unit adapted for specifying a part or all of candidate users satisfying all of conditions out of one or more users with whom a request user's friendship is built in one or more utilized applications that the request user has utilized, a first condition in which the candidate user utilizes the application identified by the identification information, a second condition in which the request user's friendship with the candidate user has not been built in the identified application, a third condition in which a friend upper limit is not encountered, and a display controlling unit adapted for displaying the part or all of the candidate users specified by the specifying unit in the terminal device of the request user in order to select one or more users from the part or all of the candidate users.

Abstract: If a management server receives an access request, the management server performs a first ranking processing. A CPU extracts records satisfying a predetermined condition by referring to a relation table, and specifies one or plural user identification information included in the extracted records. The CPU accumulates the number of the specified user identification information for each of games, and specifies descending order of popularity of the games using the accumulated number. The CPU arranges information including explanations of the games in descending order of the number of users playing the games, and generates a first ranking page. The CPU sends an access response including the first ranking page back to a terminal device.
