Abstract

A method, computer-readable media and system for providing Random Access Channel (RACH) response preamble prioritization are presented. In one embodiment a method includes receiving, from a RACH receiver at a Preamble Prioritization Element (PPE), a list of detected preambles from a plurality of User Equipment (UE) devices, the preambles having a configured priority for different preamble groups; providing, by the PPE, an ordered prioritized list of the detected preambles; and forwarding, by the PPE to a RACH response element, a predetermined number of detected preambles from the ordered prioritized list.

Claims (27)

1. A method for providing Random Access Channel (RACH) response preamble prioritization, the method comprising:

receiving, from a RACH receiver at a Preamble Prioritization Element (PPE), a list of detected preambles from a plurality of User Equipment (UE) devices, the preambles having a configured priority for different preamble groups;

providing, by the PPE, an ordered prioritized list of the detected preambles;

forwarding, by the PPE to a RACH response element, a predetermined number of detected preambles from the ordered prioritized list; and

sending a first Random Access Response (RAR) message to a UE that sent a dedicated preamble based on the ordered prioritized list.

2. The method of claim 1 further comprising configuring, by an operator, a priority of different preamble groups of UEs.

3. The method of claim 1 wherein the predetermined number of detected preambles comprises 64 preambles.

4. The method of claim 1 wherein a prioritized preamble indicates that access to a cell is required due to an incoming handover.

5. A non-transitory computer-readable medium containing instructions for providing Random Access Channel (RACH) response preamble prioritization, which, when executed, cause a system to perform steps comprising:

receiving, from a RACH receiver at a Preamble Prioritization Element (PPE), a list of detected preambles from a plurality of User Equipment (UE) devices, the preambles having a configured priority for different preamble groups;

providing, by the PPE, an ordered prioritized list of the detected preambles;

forwarding, by the PPE to a RACH response element, a predetermined number of detected preambles from the ordered prioritized list; and

sending a first Random Access Response (RAR) message to a UE that sent a dedicated preamble based on the ordered prioritized list.

6. The non-transitory computer-readable medium of claim 5 further comprising instructions for configuring, by an operator, a priority of different preamble groups of UEs.

7. The non-transitory computer-readable medium of claim 5 wherein the predetermined number of detected preambles comprises 64 preambles.

8. The non-transitory computer-readable medium of claim 5 wherein a prioritized preamble indicates that access to a cell is required due to an incoming handover.

9. A system for providing Random Access Channel (RACH) response preamble prioritization, comprising:

a Preamble Prioritization Element (PPE);

a RACH receiver in communication with the PPE;

a RACH response element in communication with the PPE;

wherein the PPE receives, from the RACH receiver, a list of detected preambles from a plurality of User Equipment (UE) devices, the preambles having a configured priority for different preamble groups;

wherein the PPE provides an ordered prioritized list of the detected preambles;

wherein the PPE forwards to the RACH response element, a predetermined number of detected preambles from the ordered prioritized list; and

wherein the PPE sends a first Random Access Response (RAR) message to a UE that sent a dedicated preamble based on the ordered prioritized list.

10. The system of claim 9 further wherein an operator configures a priority of different preamble groups of User Equipments (UEs).

11. The system of claim 9 wherein the predetermined number of detected preambles comprises 64 preambles.

12. The system of claim 9 wherein a prioritized preamble indicates that access to a cell is required due to an incoming handover.
