Method and apparatus for responding to a potential mass random access event
First Claim
1. A method for responding to a mass random access event, the method comprising:
- monitoring, at a radio controller, a radio channel for a first period of time and determining a first indication of signals received without detecting synchronization or with detecting synchronization but failing error correction during the first period of time;
responsive to determining, by the radio controller, that the first indication of signals received without detecting synchronization or with detecting synchronization but failing error correction during the first period of time is above a predetermined threshold indicative of an interference condition comprising one of an interferer and mass random access event, causing an instruction to be broadcast identifying a subset of subscriber devices, less than all subscriber devices, allowed to transmit random access requests on the radio channel;
monitoring, at the radio controller, the radio channel for a second period of time and determining a second indication of signals received without detecting synchronization or with detecting synchronization but failing error correction during the second period of time; and
if the second indication is an improvement over the first indication, determining, by the radio controller, that the interference condition is caused by the mass random access event.

Abstract
A radio controller monitors a radio channel for a first period of time and determines a first indication of signals received without detecting synchronization or with detecting synchronization but failing error correction during that time. Responsive to determining that the first indication is above a predetermined threshold indicative of an interference condition, causing an instruction to be broadcast identifying a subset of subscriber devices allowed transmitting random access requests on the radio channel. The radio controller monitors the radio channel for a second period of time and determines a second indication during that time. If the second indication is an improvement over the first indication, the radio controller determines that the interference condition is caused by the mass random access event.

17. A radio controller in a radio system, the controller comprising:
-
a transceiver; a data store; and one or more processors configured to; monitor, via the transceiver, a radio channel for a first period of time and determine a first indication of signals received without detecting synchronization or with detecting synchronization but failing error correction during the first period of time; responsive to determining that the first indication of signals received without detecting synchronization or with detecting synchronization but failing error correction during the first period of time is above a predetermined threshold indicative of an interference condition comprising one of an interferer and mass random access event, cause an instruction to be broadcast, via the transceiver, identifying a subset of subscriber devices, less than all subscriber devices, allowed to transmit random access requests on the radio channel; monitoring, via the transceiver, the radio channel for a second period of time and determining a second indication of signals received without detecting synchronization or with detecting synchronization but failing error correction during the second period of time; and if the second indication is an improvement over the first indication, determining that the interference condition is caused by the mass random access event. - View Dependent Claims (18, 19, 20)
