A method for accessing a service, corresponding first device, second device and system

摘要

The invention relates to a method 20 for accessing a service. According to the invention, a first device 14 stores data relating to at least one first service subscription. The first device stores at least one first criterion associated with each of the at least one first service subscription. A second device 18 stores data relating to at least one second service subscription. The second device stores at least one second criterion associated with each of the at least one second service subscription. The first device compares at least one requested criterion to at least one stored first criterion. If the at least one requested criterion does not match the at least one stored first criterion, then the first device sends to a second device a request 24 for loading data relating to at least one service subscription accompanied with the at least one requested criterion. The second device compares at least one requested criterion to at least one stored second criterion. And if the at least one requested criterion does match the at least one stored second criterion, then the second device sends to the first device data 26 relating to at least one second service subscription associated with the at least one stored second criterion. The invention relates also to corresponding first device, second device and system.
