Abstract
A method and node for supporting PDSN load optimization in a CDMA2000 network. The Packet Core Network Manager calculates network statistics and uses the resulting numbers to set the PPP inactivity timer depending on the load on the PDSN. In a preferred embodiment, the calculation gives the mean value of the durations of the PPP sessions (KPI1), and the corresponding standard deviation (KPI2). The PPP inactivity timer is then set to M*(KPI1+KPI2) during low load, to M*KPI1 during normal load, and to M*(KPI1−KPI2) during heavy load, where 0<M<=1, preferably depending on the distribution of the subscriber inter-arrival time.
Claims16
A method for load optimization of a first node in a telecommunications network, wherein the first node has a plurality of connections to a plurality of second nodes and wherein an inactivity timer is associated with each of the plurality of connections, the method comprising the steps of:
- collecting network data;
- selecting the relevant collected network data for calculations;
- calculating at least one value using the selected data;
- and
- setting at least one inactivity timer based on the at least one value.
A management node in a telecommunications network for management of a managed node, wherein the managed node has a plurality of connections to a plurality of second nodes and wherein an inactivity timer is associated with each of the plurality of connections, the management node comprising:
- a memory that stores network data;
- and
- a processing unit that:
- selects the relevant stored network data from the memory for calculations;
- calculates at least one value using the selected data;
- and
- sets at least one inactivity timer based on the at least one value.
