CROSS REFERENCE TO RELATED APPLICATION [0001] This application is a Continuation of application Ser. No. 09/667,519 filed Sep. 22, 2000, now pending, the entire contents of which are incorporated by reference herein. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a method for delivering data resources to a terminal device, and more specifically to a method for delivering resources to a portable handy information communications terminal. [0004] 2. Description of Related Art [0005] Conventionally, various methods of efficiently delivering data resources (hereinafter referred to simply as "resources") such as software programs, data, etc. to a terminal device have been suggested and put to practical use. [0006] For example, a method (Japanese Patent Publication No. 7-21100) of reducing the number of terminal devices which cannot receive resources by repeatedly broadcasting resources to a terminal devices from a delivering source system several times, a method (Japanese Patent Publication No. 9-146858) of generating a terminal device list for reaching a terminal device to which resources have to be delivered by referring to a relay information entered in advance, and sequentially transferring the list with the resources to an adjacent relay system, etc. are well known. [0007] However, in the method described in these publications, the configuration in which a mobile terminal (portable handy information communications terminal) is used as a destination terminal device to which resources are to be delivered has not been taken into account. [0008] A method of delivering resources to a mobile terminal can be, for example, a system (Japanese Patent Publication No. 9-245666) of receiving resources from a delivering source system through a relay device when relay devices exist between the delivering source system and a mobile terminal, and the mobile terminal enters a radio area of any relay system, etc. [0009] However, when it is not considered that a destination terminal device to which resources are to be delivered is a mobile terminal, the following problem occurs when the terminal device moves. [0010] Basically, since a resource delivering route is predetermined such that the optimum resource delivery can be attained between a source system and a destination terminal device when the destination terminal device is connected to a network at a predetermined location, the resource delivering efficiency is lowered if the terminal device is moved to another location. [0011] In a system where several relay devices exist between a delivering source system and a destination terminal device, it has not been possible to recognize onto which relay device the resources requested by a user of the destination terminal device has been downloaded has not been provided even on the assumption that the terminal device can select an available relay device. Therefore, the destination terminal sometimes can not receive the resources. [0012] In a system to which resources are periodically delivered (for example, a push-type newspaper delivering system), a terminal device may not obtain the resources if it moves from a predetermined location to another location. [0013] Furthermore, even in a method used on the assumption that a destination terminal device to which resources are to be delivered can be moved, the following problems occur. [0014] To receive resources at a moved-to location, it is necessary for a terminal device to request a delivering source system to deliver the resources after having arrived at the moved-to location. Therefore, when there is a large amount of data of the resources to be delivered, it takes a long time to obtain desired resources after arriving a destination. [0015] In the system for delivering resources at a request from a terminal device, there is a fee for the communications between the terminal device and a relay system during the transfer of the resources from a delivering source system to the relay device. Therefore, a wasteful communications cost is required when a large amount of data of resources is delivered. SUMMARY OF THE INVENTION [0016] The present invention aims at delivering data resources to a mobile terminal device without fail and improving the delivering efficiency. It also aims at providing a method of delivering resources which does not require the terminal device to consider a relay device to be connected. [0017] The resource delivering method according to the present invention is used in a system where a plurality of relay devices exist between a delivering source device which delivers resources and a terminal device which receives the resources. The method includes: notifying from the terminal device to the delivering source device of the information specifying a relay device for receiving the resources delivered from the delivering device, delivering the resources from the delivering source device to the relay device specified by the notification, and delivering the resources from the relay device to the terminal device according to an access by the terminal device. [0018] In this method, a relay device which receives the resources delivered from a delivering source device is specified by a terminal device. Therefore, the terminal device can receive desired resources through a desired relay device. It is not necessary for the terminal device to connect the line to the relay device while the resources are delivered from the delivering source device to the relay device. Therefore, there are no communications costs required between the terminal device and the relay device. [0019] In addition, the terminal device can specify several relay devices. In this case, since the resources are delivered to the specified relay devices, the terminal device can receive desired resources from any relay device the terminal devices. When one of the plurality of relay devices delivers the resources to the terminal device, the relay device notifies other relay devices that the resources have been delivered. Therefore, each relay device can discard unnecessary resources according to the notification. [0020] The resources delivering method according to another aspect of the present invention includes: notifying from the terminal device to the first relay device of information specifying the resources to be delivered, accessing from the first relay device to the delivering source device which provides the specified resources and obtaining the resources, delivering the resources from the first relay device to the second relay device, and delivering the resources from the first or second relay device to the relay device In response to an access from the terminal device. [0021] In this method, a relay device obtains the resources requested by a terminal device, and delivers the resources to another relay device. Therefore, the terminal device can receive desired resources from any relay device in a plurality of relay devices. That is, the terminal device can receive the desired resources without considering a relay device. Continue reading about Method for delivering data resources...
