Abstract

The primitives between an upper management layer and the MAC layer within a mobile station and a base station are defined in order to specify and clarify the operations within the protocol stack layers in a broadband wireless access system to allow a mobile station to perform a method of connecting to the network. Media Independent Handover (MIH) procedures can be achieved because the NCMS and MIH layer can communicate through use of these primitives.

Claims

1. A method of ranging for a broadband wireless access system, the method comprising:

receiving, from a mobile station (MS) Network Control and Management System (NCMS), a first primitive that indicates a ranging request;

transmitting a ranging request containing ranging information to a base station medium access control (MAC) layer; and

receiving a ranging response from the base station MAC layer.

2. The method of claim 1, further comprising:

sending, to the MS NCMS, a second primitive that indicates a result of the performed ranging.

3. The method of claim 1, wherein the ranging information includes an initial ranging.

4. The method of claim 3, wherein the ranging information further includes at least one of a handover (HO) ranging, location update ranging, and periodic ranging.

5. The method of claim 1, wherein the ranging request indicates network entry.

6. The method of claim 5, wherein the network entry is for entry to a 802.16 network.

7. The method of claim 2, wherein the above steps are repeated until ranging is successful.

8. The method of claim 1, wherein the ranging request includes a CODE or a MAC ADDRESS.

9. A method of ranging for a broadband wireless access system, the method comprising:

receiving, from a mobile station (MS) medium access control (MAC) layer, a ranging request message containing ranging information; and

sending, to a base station (BS) Network Control and Management System (NCMS), a first primitive that indicates a ranging request has been received.

10. The method of claim 9, wherein the ranging information includes at least one of a CDMA code, MS MAC address, MAC version, requested downlink burst profile, serving BS ID, target BS ID, handover (HO) indication, location update request, and paging controller ID.

11. The method of claim 9, further comprising:

receiving, from the BS NCMS, a second primitive that indicates a ranging has been performed; and

transmitting, to the MS MAC, a ranging response.

12. The method of claim 11, wherein the ranging response contains information of the second primitive that includes at least one of Result Code, Management CIDs, resource retain flags, handover (HO) process optimization, location update response, paging information, paging controller ID, next periodic ranging.

13. A method of registration for a broadband wireless access system, the method comprising:

receiving, from a base station (BS), a registration response; and

sending, to a Network Control and Management System (NCMS), a second primitive indicating registration confirmation.

14. The method of claim 13, wherein the second primitive comprises at least one of a method of allocation an IP address, IP version, and skip address acquisition.

15. The method of claim 14, wherein the method of allocation an IP address includes DHCP, mobile IPv4, DHCP v6, IPv6 stateless address autoconfiguration.

16. The method of claim 14, wherein the skip address acquisition includes at least one of no IP address change, and re-acquire IP address.

17. The method of claim 13, wherein the receiving procedure indicates that network entry has been completed.

18. The method of claim 13, further comprising:

receiving, from a MS NCMS, a first primitive to request registration; and

sending, to a BS MAC, a registration request message.

19. The method of claim 18, wherein the first primitive comprises at least one of IP version, method of allocation IP address, previous IP address.

20. The method of claim 19, wherein the method of allocating an IP address includes DHCP, mobile IPv4, DHCP v6, IPv6 stateless address autoconfiguration.

21. A method of registration for a broadband wireless access system, the method comprising:

receiving, from a mobile station (MS) medium access control (MAC) layer, a registration request message;

sending, to a base station (BS) Network Control and Management System (NCMS), a first primitive that indicates a registration indication;

receiving, from the BS NCMS, a second primitive that indicates a registration response; and

sending, to the MS MAC, a registration response message.

22. The method of claim 21, wherein the first primitive comprises at least one of IP version, method of allocation IP address, previous IP address.

23. The method of claim 22, wherein the method of allocating an IP address includes DHCP, mobile IPv4, DHCP v6, IPv6 stateless address autoconfiguration.

24. The method of claim 21, wherein the second primitive comprises at least one of a method of allocation an IP address, IP version, and skip address acquisition.

25. The method of claim 24, wherein the method of allocation an IP address includes DHCP, mobile IPv4, DHCP v6, IPv6 stateless address autoconfiguration.

26. The method of claim 24, wherein the skip address acquisition includes at least one of no IP address change, and re-acquire IP address.

27. A method of registration for a broadband wireless access system, the method comprising:

receiving, from a Network Control and Management System (NCMS), a second primitive that indicates a result of a performed registration in order to receive an indication that a link setup procedure has been completed,

wherein the second primitive is sent and received via at least one of a management service access point (M-SAP) and a control service access point (C-SAP).

28. The method of claim 27, wherein the second primitive comprises at least one of a method of allocation an IP address, IP version, and skip address acquisition.

29. The method of claim 28, wherein the method of allocation an IP address includes DHCP, mobile IPv4, DHCP v6, IPv6 stateless address autoconfiguration.

30. The method of claim 28, wherein the skip address acquisition includes at least one of no IP address change, and re-acquire IP address.

31. The method of claim 27, further comprising, before the receiving step:

sending, to a Network Control and Management System (NCMS), a first primitive that indicates a registration request,

wherein the first primitive is sent and received via at least one of a management service access point (M-SAP) and a control service access point (C-SAP).
