Random access channel preamble assignments for dual connectivity

A system for suspect device filtering in a wireless communication network, the system comprising:

• a first node configured to wirelessly communicate with a UE;
• a second node configured to wirelessly communicate with the UE;
• one or more computer processing components communicatively coupled to each of the first node, the second node, and the UE, and configured to perform a method comprising:
• receiving, from the UE, one or more call quality indicators indicating that the UE is requesting access to each of the first node and the second node, wherein the one or more call quality indicators comprises an allocation and retention priority;
• communicating a first random access preamble for a first random access procedure and a second random access preamble for a second random access procedure to the UE, wherein the first random access procedure is used by the UE to access the first node and the second random access procedure is used by the UE to access the second node.

One or more non-transitory computer-readable media having computer-executable instructions embodied thereon that, when executed, cause the one or more processors to perform a method comprising:

• receiving, from the UE, one or more call quality indicators indicating that the UE is requesting access to a dual connectivity connection, wherein the one or more call quality indicators comprises an allocation and retention priority;
• determining, based at least in part on the one or more call quality indicators, a priority level associated with the UE;
• based on a determination that the priority level exceeds a predetermined threshold, communicating a random access preamble to the UE for use in contention free random access;
• and
• based on a determination that the priority level is below the predetermined threshold, withholding a random access preamble from the UE.
