  • Method, chip and system for detecting a failure in a PDP context or an EPS PDN connection
    Patent number: 11019672
    Abstract: The invention relates to a method for detecting a failure in a PDP context or an EPS PDN connection. A chip incorporated within or coupled to a device receives from the device a call control PDP context activation type event or a call control EPS PDN connection activation type event. The chip receives from the device an updated value relating to an HFN start PS. The chip compares the last updated value relating to the HFN start PS to a predetermined value relating to the HFN start PS. If the last updated value relating to the HFN start PS is greater than or is less than/equal to the predetermined value relating to the HFN start PS, then the chip detects that the PDP context or the EPS PDN connection has been successfully or unsuccessfully activated respectively.
