Abstract

Embodiments of systems and methods for distributed control relay architecture are described herein. Other embodiments may be described and claimed.

Claims

1. An advanced mobile station (AMS) comprising a transceiver to communicate with an access service network (ASN) through an advanced relay station (ARS) and over an R6 interface between the ARS and an ASN gateway (GW), wherein the AMS is configured to interface with the ARS to perform initial ranging, to receive a station identifier (STID) wherein the STID is assigned by the ARS to the AMS, to receive a flow identifier assignment from the ARS, and to receive control operations messages from the ARS, wherein the control operations are performed by the ARS.

2. The AMS of claim 1, wherein the ARS transmits the STID to an advanced base station (ABS) coupled to the ARS.

3. The AMS of claim 1, wherein the AMS is further configured to execute capability negotiation, authentication/key agreement, and registration procedures with the ARS.

4. The AMS of claim 1, further comprising transmitting a range request (AAI_RNG-REQ) message to the ARS during initial ranging.

5. The AMS of claim 1, wherein the control operations comprise handover, security, sleep, and idle control operations.

6. The AMS of claim 1, wherein the AMS communicates through the ARS using an R1 a interface with control plane and bearer plane protocols.

7. The AMS of claim 1, wherein the STID is a temporary STID (TSTID).

8. The AMS of claim 5, wherein the AMS is configured to receive a STID and a flow identifier from the ARS during a handover operation.

9. A method for wireless networking in a distributed control architecture using an advanced mobile station (AMS), comprising:

performing initial ranging with an advanced relay station (ARS) by transmitting a range request (AAI_RNG-REQ) message from the AMS to the ARS;

receiving a station identifier (STID) from the ARS, wherein the STID is assigned to the AMS by the ARS;

receiving a flow identifier (FID) assignment from the ARS, wherein the FID is assigned to the AMS by the ARS; and

receiving control operation messages from the ARS, wherein the control operations are performed by the ARS.

10. The method of claim 9, wherein the AMS communicates through the ARS using an R1a interface.

11. The method of claim 9, wherein the AMS communicates with an access service network through the ARS and over an R6 interface between ARS and an access service network gateway (ASN-GW).

12. An advanced relay station (ARS) comprising a transceiver to communicate with an advanced mobile station (AMS), an advanced base station (ABS) and an access service network gateway (ASN-GW), wherein the ARS is configured to interface with the AMS to perform initial ranging, to transmit a station identifier (STID) assigned by the ARS to the AMS, to transmit a flow identifier assigned by the ARS to the AMS, and to communicate with the ASN-GW over an R6 interface through the ABS.

13. The ARS of claim 12, further comprising transferring control messages between the ARS and the ASN-GW over the R6 interface and between the ARS and the ABS or a second ARS over an R8 interface.

14. The ARS of claim 13, wherein the control messages are formatted as L2 transfer messages (AAI_L2-XFER).

15. The ARS of claim 14, wherein transport headers are removed, from control messages received from the ASN-GW, by the ABS.

16. The ARS of claim 12, further comprising managing control functions for the AMS.

17. The ARS of claim 16, wherein the control functions comprise sleep operations, idle mode operation, and deregistration operations.

18. A method for wireless networking in a distributed control architecture using an advanced relay station (ARS), comprising:

performing initial network entry with an advanced mobile station (AMS);

transmitting a station identifier (STID) assigned by the ARS to the AMS;

transmitting a flow identifier (FID) assigned by the ARS to the AMS, and;

communicating with an access service network gateway (ASN-GW) over an R6 interface through an ABS.

19. The method of claim 18, further comprising managing control functions for the AMS.

20. The method of claim 19, wherein the control functions comprise sleep operations, idle mode operation, and deregistration operations.

21. The method of claim 18, wherein the ARS communicates with the ASN-GW directly over the R6 interface.

22. The method of claim 18, wherein the ABS performs routing optimization on data transferred through the ABS.
