An internet-connected service system is provided for facilitating communication across the internet between image-sending and image-receiving systems that have dial-up internet access. The image-sending system, after connecting to the internet, sends a communication request to the service system and the latter is then responsible for waking up the image-receiving system. Upon being woken up, the image-receiving system connects to the internet and contacts the service system. The service system then transfers the current network address of at least one of the systems to the other thereby enabling direct communication to be established between the image-sending and image-receiving systems.

Communications arrangement and method using service system to facilitate the establishment of end-to-end communication over a network

A communications infrastructure is provided with a service system that facilitates the setting up of data transfer operations between end systems connected to the infrastructure. When a first end system wishes to initiate a data transfer operation, it contacts the service system and establishes a transfer-operation characteristic for the proposed data transfer operation that is known both to itself and the service system. The first end system then contacts the target end system with which it wishes to effect a data transfer operation and passes it the aforesaid transfer-operation characteristic. The target end system uses the received transfer-operation characteristic to check with the service system that the proposed data transfer from the first end system is known and acceptable to the service system; only if this check is passed does the target end system proceed with the data transfer operation proposed by the first end system. With this arrangement, the target end system can be sure that it only participates in data transfer operations with parties vetted by the service system.
