A method for providing a combined service consisting of partial services (STN, STA, STB, STC) in a peer-to-peer network comprising peer devices (A 1, B 1 -B 5, C 1 -C 5, N 1 -N 4), wherein the peer devices (A 1, B 1 -B 5, C 1 -C 5, N 1 -N 4) can be associated with groups (SG B, SGc, SG N), wherein each group (SG B, SGc, SG N) is determined by a predetermined partial service (STB, STC, STN), characterized in that the partial services (STN, STA, STB, STC) are to be executed linked and successively, wherein, by means of each peer device (B 1 -B 5, C 1 -C 5, N 1 -N 4) associated with a respective group (SG B, SGc, SG N), the predetermined partial service (STB, STC, STN) can be executed, and a selected peer device (cB 3, cC 1, cN 4) of a group executes the respective partial service (STB, STC, STN), wherein a sequence of partial services (STN, STC, STB, STA) to be executed and specifications to the peer devices which are to execute the respective partial service (STA, STB, STC, STN) are published in the peer-to-peer network by a peer device (A 1) requesting the combined service, and the selection of the selected peer devices (cB 3, cC 1, cN 4) as a function of the published sequence and the published specifications occurs, wherein, for the initializing of the combined service, the following process steps are carried out: a) publishing of a ComposedServiceResource, which comprises the sequence of the partial services used for the execution of the combined service, in particular criteria for the selection of the executing peer devices, a linking of the partial services and execution parameters for the partial services; b) publishing of a SubtaskResource (STR B) for the requesting of the partial service, to be executed last in the sequence of the partial services, by the peer device (A 1) requesting the combined service, wherein an identification of the peer device (A 1) requesting the partial service, as transfer peer device for a partial service result, is written by the requested partial service into the SubtaskResource (STR B), and selecting of the peer device (cB 3) of the group which is to execute the requested partial service; and c) publishing of additional SubtaskResources (STR C, STR N) for requesting the partial service (STC, STN), to be executed in each case in the sequence of the partial services, by the selected peer device (cB 3, cC 1) which executes the partial service (STB, STC) to be executed in each case subsequently in the sequence of the partial services, wherein an identification of the peer device (cB 3, cC 1) requesting the partial service result is written as transfer peer device for a partial service result is written by the requested partial service (STB, STC) into the SubtaskResource (STR C, STR N), and selecting of the peer device (cC 1, cN 4) of the group which is to execute the requested partial service (STC, STN). a) publishing of a ComposedServiceResource, which comprises the sequence of the partial services used for the execution of the combined service, in particular criteria for the selection of the executing peer devices, a linking of the partial services and execution parameters for the partial services; b) publishing of a SubtaskResource (STR B) for the requesting of the partial service, to be executed last in the sequence of the partial services, by the peer device (A 1) requesting the combined service, wherein an identification of the peer device (A 1) requesting the partial service, as transfer peer device for a partial service result, is written by the requested partial service into the SubtaskResource (STR B), and selecting of the peer device (cB 3) of the group which is to execute the requested partial service; and c) publishing of additional SubtaskResources (STR C, STR N) for requesting the partial service (STC, STN), to be executed in each case in the sequence of the partial services, by the selected peer device (cB 3, cC 1) which executes the partial service (STB, STC) to be executed in each case subsequently in the sequence of the partial services, wherein an identification of the peer device (cB 3, cC 1) requesting the partial service result is written as transfer peer device for a partial service result is written by the requested partial service (STB, STC) into the SubtaskResource (STR C, STR N), and selecting of the peer device (cC 1, cN 4) of the group which is to execute the requested partial service (STC, STN).
