Abstract
A method for relocating network gateways comprises the steps of obtaining a moving average of drop ratios and setting the duration of the next detection interval based on the moving average of drop ratios, and requesting at least one mobile station to perform a CSN mobility management procedure when the moving average of drop ratios exceeds a high drop ratio.
Claims20
A method for relocating network gateways comprising the steps of:
- calculating a moving average of drop ratios for an xth detection interval, wherein x is an integer;
- setting an (x+1)th detection interval as a long detection interval when the moving average of drop ratios is less than a low drop ratio;
- setting the (x+1)th detection interval as a short detection interval when the moving average of drop ratios is equal to or exceeds the low drop ratio;
- and
- performing a user relocation function when the moving average of drop ratios for the xth detection interval is equal to or exceeds a high drop ratio, wherein the user relocating function comprises requesting at least one user device to activate a connectivity service network (CSN) mobility management procedure.

A method of relocating network gateways comprising the steps of:
- calculating a moving average of drop ratios for an xth detection interval, wherein x is an integer;
- setting the (x+1)th detection interval according to a low drop ratio and the moving average of drop ratios;
- performing a user relocation function when the moving average of drop ratios is equal to or exceeds a high drop ratio, wherein the user relocation function comprises requesting at least one user device to activate a connectivity service network (CSN) mobility management procedure;
- estimating a predicted moving average when the moving average of drop ratio is less than the high drop ratio and is equal to or exceeds the low drop ratio;
- and
- performing the user relocation function when the predicted moving average is equal to or exceeds the high drop ratio.
3 more elements
A network gateway comprising:
- a processor for calculating a moving average of drop ratios within a detection interval and updating the next detection interval according to the moving average of drop ratios;
- and
- a user interface for requesting at least one user device activating a connectivity service network (CSN) mobility management procedure when the moving average exceeds a high drop ratio, wherein the user device is using an anchored mobility service.
