METHOD AND SYSTEM FOR LAST GASP DEVICE DETECTION
First Claim
1. A method for device detection by a base station comprising:
- receiving a plurality of signals over a preamble subframe from an endpoint, the plurality of signals attempting to access an access group of the preamble subframe, the plurality of signals received on a random access channel using a wireless network, the plurality of signals having a plurality of last gasp messages (LGMs);
determining an allowable rate of collisions for the plurality of signals;
determining an actual rate of collisions for the plurality of signals; and
increasing the size of the access group allocated to the plurality of signals having the plurality of LGMs, based on whether the actual rate of collisions exceeds the allowable rate of collisions.

Abstract
A method is provided for device detection by a base station comprising receiving a plurality of signals over a preamble subframe from an endpoint. The plurality of signals are attempting to access an access group of the preamble subframe. Additionally, the plurality of signals are received on a random access channel using a wireless network. Further, the plurality of signals have a plurality of last gasp messages (LGMs). The method additionally comprises determining an allowable rate of collisions for the plurality of signals and determining an actual rate of collisions for the plurality of signals. The method includes increasing the size of the access group allocated to the plurality of signals having the plurality of LGMs, based on whether the actual rate of collisions exceeds the allowable rate of collisions.
