Method of updating a location information representing a physical location of a communication device, a computer program product for executing the method, and a communication system for updating the location information

A communication system for updating a location information that represents a physical location of a communication device generated by a location source, and that is sent from the location source to a location consumer, the communication system comprising:

• a caching unit having non-transitory memory to store a first location information;
• a location object generating unit comprising a component of the communication device or a component of the location source, the location object generating unit configured to monitor a second location information received subsequently to the first location information at the location object generating unit to detect an invalid location information included in the second location information,
• the communication system being configured such that, triggered by the detection of the invalid location information of the second location information received after the first location information, a location object is generated by the location object generating unit to send from the location object generating unit to the cache unit, wherein the location object comprises an invalidation information indicating that stored first location information is to be discarded by the cache unit so that the cache unit discards the first location information from the memory in response to the location object.
