We disclose a method for reliable message delivery between three parties in a network of mobile devices. This method consists of augmenting the services provided by a Network Service Provider (NSP) or a similar entity with a method combining store-and-forward of messages and a token which is stored in the mobile computer. This token represents an identifier of the last point-of-presence used for connecting to the network and it is used for inquiring about previous requests. Thereby, guaranteeing delivery of requests in spite of lack of resources availability.

Method for reliable message delivery in a network of mobile computers

The invention is a method for coordinating actions among a server supporting multiple independent client server requests and participating clients making multiple independent web requests. The requests are communicated between the client and the server using a protocol that has limited or no defined procedures for passing state information between the client and the servers. A client transmits a request for a first action to a server that requires transaction scope. The server generates transaction identification information and maintains it across the duration of multiple independent and state-less web requests. The client then transmits a request for a additional actions to the server that requires transaction scope, using the transaction identification information preserved in the conversation and maintained by the servers including the client's request in the transaction and transmitting a request by a client to a server that requires transaction completion.
