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 a first primitive comprising a type field indicating a location update, wherein the first primitive causes the location update to be performed via a transmission of a ranging request from a mobile station (MS) Network Control and Management System (NCMS) to a base station (BS);

transmitting the ranging request comprising ranging information to the BS to perform the location update, wherein the ranging information is related to the location update;

receiving a ranging response from the BS; and

transmitting a second primitive to the MS NCMS to provide a result of the ranging response, wherein the second primitive comprises a location update result, a paging controller ID and a paging information,

wherein the paging information is only included when the location update result indicates a successful location update, and wherein the paging information comprises a paging offset, a paging group ID and a paging period.

2. The method of claim 1, wherein the ranging information further comprises an initial ranging.

3. The method of claim 2, wherein the ranging information further comprises at least a handover (HO) ranging or a periodic ranging.

4. The method of claim 1, wherein the ranging request comprises network entry.

5. The method of claim 4, wherein the network entry is for entry to a metropolitan area network (MAN).

6. The method of claim 1, further comprising receiving the first primitive, transmitting the ranging request, receiving the ranging response, and sending the second primitive until ranging is successful.

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

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

receiving a ranging request message comprising ranging information from a mobile station (MS), wherein the ranging information is related to a location update;

sending a first primitive comprising a paging controller ID and indicating to a base station (BS) Network Control and Management System (NCMS) that a ranging request has been received;

receiving a second primitive to request transmission of a ranging response, wherein the second primitive comprises a location update result, paging controller ID, and paging information,

wherein the paging information is only included when the location update result indicates a successful location update, and wherein the paging information comprises a paging offset, a paging group ID and a paging period; and

transmitting the ranging response to the MS.
