The invention relates to a system and a method for determining an ideal configuration of a network especially on the basis of the behavior of a simulated network.
Generally, in times of a steadily growing volume of data to be exchanged and an increasing number of networks, there is a growing need of a system and a method for determining an ideal network configuration in a most efficient manner in order to allow for a highly performant and low-cost network.
U.S. Pat. No. 6,631,128 B1 relates to the management of communications networks and, in particular, to the optimization of topology and technology types within a network to support certain traffic types. Disadvantageously, the core network optimization according to said document is not based on a simulated network, which results in high costs because network optimizations have to take place in the field, which leads to the disadvantage that a longer time is required for implementing the network.

A system and a method for determining an ideal configuration of a network on the basis of the behavior of a simulated network are described. In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the invention. It is apparent, however, that the invention may be practiced without these specific details or with an equivalent arrangement.

According to
The network simulation means 12 provides a simulated network, to which the device under test 15 (e.g., a wireless communication device) is connected. Additionally, the ideal configuration of the network is determined based on the behavior of the simulated network provided by the network simulation means 12.
Moreover, with the aid of the analyzer means 13 and the connection between the simulation means 12 and the analyzer means 13, the data traffic is captured.
Advantageously, the calculation means 14 is configured to determine the ideal network configuration based on the data traffic.
Further advantageously, the analyzer means 13 determines an inactivity timer of the network based on the data traffic. By way of example, the inactivity timer may be a discontinuous reception (DRX) inactivity timer or a short DRX cycle timer or a DRX short cycle timer or a long DRX cycle timer or a DRX retransmission timer or an on-duration timer or a DRX cycle timer.
In addition to this, the inactivity timer may be comprised by a base station of the network. Advantageously, with the aid of the optimal configuration of the inactivity timer, energy can be saved and resources of the network are used in an efficient manner.
Furthermore, also with respect to the network, data of the network may comprise both payload and signaling data.
At this point, as it can be seen, the system 10 for determining the ideal configuration of the network provides the benefit that the optimal configuration of a network can be found in a laboratory environment without the need of expensive network configuration tests done in live networks. As a result, time and costs are significantly reduced.
Moreover, with respect to the device under test 15, the device under test 15 may comprise a defined set of applications (e.g., the three different applications 16, 17, and 18, as shown in
In this context, the analyzer means 13 can advantageously identify a single application ora set of applications of the device under test 15.
