1. A packet data serving node (PDSN) within a PPP network, comprising:

  • a bus coupled to a processor for transmitting computer instructions and control signals to and from the processor within the PDSN;

    memory coupled to the bus, the memory including computer instructions that define operational logic for causing the PDSN to operate a PPP inactivity timer and to generate at least one Link Control Protocol (LCP) Echo Request signal to a mobile terminal upon expiration of the PPP inactivity timer;

    the processor for executing computer instructions wherein the processor retrieves the computer instructions from the memory over the bus and executes the computer instructions to generate a first LCP Echo Request; and

    wherein the PDSN further generates and produces a PPP inactivity time remaining timer value for transmission to the mobile terminal wherein the PPP inactivity time remaining timer is value is less than or equal to a sum of the PPP inactivity timer value plus an Echo Reply-Timeout timer value times the sum of Echo Request Retries+1 and wherein the value of the PPP inactivity time remaining timer value is greater than the PPP inactivity timer and further wherein the Echo Request Retries is greater than or equal to zero.
