In order to avoid the overload of HeNB-GW, SCTP signaling measurements data will be combined with HeNB-GW user plane measurement data to reflect load status on HeNB-GW. When HeNB GW is present in HeNS, it is fairly a straightforward way to collect such performance data from HeNB GW. Especially, operators deploy a dedicated HeNS management system.

In addition, the ratio of signaling to data bandwidth usage is very useful to monitor some abnormal events, such as if the ratio of them is too high, some unusual events are possible happened. Therefore, the operator could analyze whether some problems exist in the network or not, and may find out root-causes leaded to the bad conditions, finally resolve the problems.
