Abstract: An apparatus, method, computer program product and system are provided for initiating a request for acknowledgment of successfully, or unsuccessfully, transmitted data packets, wherein the request is initiated in response to the detection of a potential overload situation or an upcoming resource limitation. In particular, a transmitter may monitor certain resources associated with the transmitter, such as memory consumption or processing capacity, and automatically request that a receiver transmit an acknowledgement when a potential overload of one or more of the resources is detected. This may occur, for example, when it is determined that memory consumption has exceeded a predefined threshold or that the processing capacity has been substantially exhausted, to name a few.

Abstract: A method and a corresponding device for optimising a cellular telecommunication network are provided. According to the provided method, an emulating device is connected to the cellular telecommunication network, thus creating a signalling link between the emulating device and the cellular telecommunication network. With the emulating device, functionalities of elements of the cellular telecommunication network are emulated and data traffic is created to an air interface of the cellular telecommunication network. The effects of created data traffic on the cellular telecommunication network are then measured and the cellular telecommunication network is adjusted on the basis of the measurements.
