Abstract

A method is provided for managing a wireless network traffic by comprising designating a first resource block of a first base station for access by a random access channel (RACH). The method additionally comprises designating a first plurality of random access subframes associated with the first resource block for access by a user-over-control plane message, and receiving a random access signal at the first base station over a subframe from an endpoint. The random access signal is received on the RACH using a wireless network and is attempting to access one of the first plurality of designated random access subframes. Further, the method comprises determining if the random access signal is a user-over-control plane message, and processing the random access signal on the one of the first plurality of designated random access subframes.

Claims (45)

1. A method for managing a wireless network traffic comprising:

designating a first resource block of a first base station for access by a random access channel (RACH);

designating a first plurality of random access subframes associated with the first resource block for access by a user-over-control plane message;

receiving a random access signal from a concentrator that collects the random access signal from an endpoint;

forwarding the random access signal to the first base station over a random access subframe, the random access signal received on the RACH using the wireless network, the random access signal attempting to access one of the first plurality of designated random access subframes; determining if the random access signal is the user-over-control plane message;

in response to determining the random access signal is the user-over-control plane message, processing the random access signal on the one of the first plurality of designated random access subframes;

receiving the random access signal from a concentrator that collects the random access signal from an endpoint at a second base station;

designating a second resource block of the second base station for access by the RACH, the second resource block corresponding to the first resource block of the first base station; and

designating a second plurality of random access subframes associated with the second resource block for access by the user-over-control plane message, the second plurality of random access subframes corresponding to the first plurality of random access subframes.

2. The method of claim 1 , wherein the random access signal is received from the endpoint in idle mode.

3. The method of claim 1 , further comprising designating a second plurality of random access subframes associated with the first resource block for access by a RACH message.

4. The method of claim 1 , wherein the second resource block corresponding to the first resource block comprises the second resource block time-aligned with the first resource block.

5. The method of claim 4 , wherein the first plurality of random access subframes and the second plurality of random access subframes comprise signatures based on a Zadoff-Chu (ZC) root with a plurality of cyclical time shifts.

6. The method of claim 4 , wherein the first plurality of random access subframes and the second plurality of random access subframes comprise signatures based on a plurality of ZC roots.

7. The method of claim 1 , wherein the random access signal is one of a concatenated message, a last gasp message, and a mass scale triggered event message.

8. The method of claim 1 , wherein the first plurality of random access subframes and the second plurality of random access subframes are designated on a semi-static basis.

9. The method of claim 1 , wherein the first base station and the second base station are located based in part on an immunity radius.

10. One or more non-transitory computer-readable media embodying logic that, when executed by a processor, is configured to perform operations comprising:

designating a first resource block of a first base station for access by a random access channel (RACH);

designating a first plurality of random access subframes associated with the first resource block for access by a user-over-control plane message;

receiving a random access signal from a concentrator that collects the random access signal from an endpoint;

forwarding the random access signal to the first base station over a subframe, the random access signal received on the RACH using a wireless network, the random access signal attempting to access one of the first plurality of designated random access subframes;

determining if the random access signal is the user-over-control plane message;

in response to determining the random access signal is the user-over-control plane message, processing the random access signal on the one of the first plurality of designated random access subframes;

receiving the random access signal from a concentrator that collects the random access signal from an endpoint at a second base station;

designate a second resource block of the second base station for access by the RACH, the second resource block corresponding to the first resource block of the first base station; and

designate a second plurality of random access subframes associated with the second resource block for access by the user-over-control plane message, the second plurality of random access subframes corresponding to the first plurality of random access subframes.

11. The media of claim 10 , wherein the random access signal is received from the endpoint in idle mode.

12. The media of claim 10 , further comprising designating a second plurality of random access subframes associated with the first resource block for access by a RACH message.

13. The media of claim 10 , wherein the second resource block corresponding to the first resource block comprises the second resource block time-aligned with the first resource block.

14. The media of claim 13 , wherein the first plurality of random access subframes and the second plurality of random access subframes comprise signatures based on a Zadoff-Chu (ZC) root with a plurality of cyclical time shifts.

15. The media of claim 13 , wherein the first plurality of random access subframes and the second plurality of random access subframes comprise signatures based on a plurality of ZC roots.

16. A base station system for wireless communication comprising:

a memory;

a processor coupled to the memory, the processor configured to:

designate a first resource block of a first base station for access by a random access channel (RACH);

designate a first plurality of random access subframes associated with the first resource block for access by a user-over-control plane message;

receive a random access signal from a concentrator that collects the random access signal from an endpoint;

forward the random access signal to the first base station over a subframe, the random access signal received on the RACH using a wireless network, the random access signal attempting to access one of the first plurality of designated random access subframes;

determine if the random access signal is the user-over-control plane message; and

in response to determining the random access signal is the user-over-control plane message, process the random access message on one of the first plurality of designated random access subframes; and

a second processor configured to: the random access signal from a concentrator that collects the random access signal from an endpoint at a second base station;

designate a second resource block of the second base station for access by the RACH, the second resource block corresponding to the first resource block of the first base station; and

designate a second plurality of random access subframes associated with the second resource block for access by the user-over-control plane message, the second plurality of random access subframes corresponding to the first plurality of random access subframes.
