Embodiment Construction

[0037] The known methods for establishing a connection between a service requester (client) 1 and a service provider (server) 3 in the Ad Hoc network 8 are shown in FIGS. 1-4. For the sake of clarity, the different method steps are shown separately in FIGS. 1-4. In the illustrated implementation, the Ad Hoc network 8 includes a service requester (client) 1 who intends to call a certain service from the network 8. In addition, there are multiple radio stations 2 in the Ad Hoc network 8. These radio stations can also be mobile and can provide different services. All radio stations in the Ad Hoc network 8 are routers, and can establish connections to other radio stations in the Ad Hoc network 8 through the adopted routing protocol. Two specific stations passing the required service of the service requester (client) 1 are assigned the reference numeral 3. The two stations are then called service providers (servers) 3. The drawings described show:

Abstract

The invention relates to method for producing a link between a person requesting a service (Client) (1) and a service provider (Server) 3 in a decentralized mobile radio network (8) with a service / service provider search service (Service Discovery) wherein the person requesting the service (Client) sends a Service Discovery Request (SD-REQ) (4) in the form of a multicast message to locally adjacent stations (2) of the decentralized mobile radio network (8) in order to localize an as yet unknown service provider (Server) (3) who can provide the desired service, said stations being IP routers, and said stations forward the multicast message to neighboring stations (2) thereof before finally forwarding it to the service provider (Server) 3 who replies with a Service Discovery Reply (SD-REP).The message is characterized in that the routing information of the Service Discovery Request and the Service Discovery Reply are added to the routing tables of the stations (2) in order to retrace the way back to the person requiring the service (Client) (1).

Description

Technical field [0001] The present invention relates to a method for establishing a connection between a service requester (client) and a service provider (server) in a decentralized mobile radio network with a service- / service provider-search service (service discovery), wherein the The service requester (client) sends a service request in the form of a multicast message to the local neighboring station as an IP router of the distributed mobile radio network in order to locate an unknown service provider (server) that provides the required service. Message (service discovery request=SD-REQ), and these stations continue to transmit the multicast message to their neighboring stations, and finally to the service provider (server), the service provider uses the response message (service Find response=SD-REP) to respond. Background technique [0002] In the future public broadband radio network, the routing mechanism (path search mechanism) of the Ad Hoc (special) network (preferabl...
