Apparatus and Method to Reduce Denial of Service During MME Overload and Shutdown Conditions

摘要

A communication device configured to perform a load balancing procedure in response to a mobility management entity being overloaded and/or shut down. The base station can be configured to generate a radio resource control (RRC) Connection Reject message including a load balancing clause. The communication device can be configured to initiate a load balancing procedure based on the RRC Connection Reject message. The communication device can also be considered to initiate a load balancing procedure after a predetermined wait time has expired and/or after a predetermined number of received RRC Connection Reject messages.

1. A base station, comprising:
a transceiver configured to communicate with a communication network; and processor circuitry communicatively coupled to the transceiver, the processor circuitry configured to:
receive a first connection request from a communication device,send a connection reject message to the communication device,receive a second connection request from the communication device, wherein the second connection request is sent by the communication device in response to a determination by the communication device that a number of connection request messages received by the communication device is greater than or equal to a predetermined threshold amount, andsend a connection setup message to the communication device in response to receiving the second connection request.
