The present invention provides a method, a network device and a system for allowing for resuming a preceding incomplete synchronization session is provided, wherein the preceding incomplete synchronization session has been interrupted during its performing. In principle the resuming of the preceding incomplete synchronization session is based on the following operations according to the inventive concept. A communication connection for synchronization of data between a first and a second device is establishing. The first and the second device comprise each a predefined set of data records to be synchronized. A first and a second update identifier are communicated between the first and the second device. The first update identifier specifies a preceding complete synchronization session having been performed between them and the second update identifier specifies a preceding incomplete synchronization session having been performed between them. Synchronization related information is exchanged between the first and the second device. The herein exchanged synchronization related information comprises that part of synchronization related information which has not been exchanged during the preceding incomplete synchronization session. Data in the first device and the second device is synchronized in accordance with the exchanged synchronization related information. The contents of the first update identifier is updated with the contents of the second update identifier.

Method, device and system for synchronizing of data providing for the handling of an interrupted synchronization process

The present invention provides a method for generating a request for information about a data store. The request codes a data store descriptor which is used to characterize or identify a matching data store from a plurality of data stores. The re-transmitted information comprises retrieved information necessary for the requesting device or the applications executed thereon to access the identified data store, respectively. The present invention provides a method for generating a response in consequence on receiving a request for information a about data store. The data store descriptor coded in the request is used to characterize or identify a matching data store from a plurality of data stores and information about the data store is retrieved. This retrieved information coded in a response is transmitted to the previously requesting device enabling the requesting device or the applications executed thereon to access the identified data store, respectively.
