Inventor: TAKAMAKI TIMO
IPC: H04L12/56
Filed: 2000-09-20
Abstract: Methods and apparatus for signal monitoring of messages in a telecommunications network having a plurality of switches and network elements therein alleviate the need for external hardware to be hooked up to nodes of the network to determine whether faults have occurred at the nodes. A signal monitoring application disclosed herein stores related message signals and messages in a relational database wherein messages and signals having common elements can be easily and quickly viewed. The SIMO  application cross-references the messages and signals in the relational database according to a transaction table which categorizes and stores the messages according to parameters set out in the transaction table. This allows the messages to be ranked and viewed very quickly without the need to process them and expend valuable computational time and resources.

Abstract: A power management scheme for use in a wireless device reduces the power consumption of the network interface module of the wireless device by selectively putting the network interface module into a low-power state for an idle time.  The length of the idle time is calculated such that the amount of delayed traffic data accumulated is expected to be less than or equal to a pre-selected threshold when the network interface module is put in the low-power state for the calculated idle time. The amount of delayed traffic data as a function of the idle time is modeled using average inter-arrival and service rates that are derived from traffic statistics data.
