Abstract

A broadband wireless access communication system including a serving BS which broadcasts a MOB_NBR-ADV message to an MS is provided. A method for configuring the MOB_NBR-ADV message is also provided, and includes adding a specific field, which represents whether at least one information field constituting the MOB_NBR-ADV message exists, to the MOB_NBR-ADV message, determining if at least one information field is included in the MOB_NBR-ADV message, and determining a bit value of the specific field according to whether at least one information field is included in the MOB_NBR-ADV message.

Claims

1. A method for transmitting a neighbor base station advertisement (MOB_NBR-ADV) message by a base station (BS) in a broadband wireless access communication system, the method comprising:

transmitting the MOB_NBR-ADV message, wherein the MOB_NBR-ADV message includes a first field including m bits, where m is an integer greater than or equal to 1, wherein when m information fields can be included in the MOB_NBR-ADV message, the m bits indicate whether any of the m information fields may be omitted from the MOB_NBR-ADV message, respectively; and

wherein, when a value of one of the m bits indicates that one of the m information fields may be omitted, the one of the m information fields is omitted from the MOB_NBR-ADV message, and when the value of the one of the m bits indicates that the one of the m information fields may not be omitted, the one of m information fields is not omitted from the MOB_NBR-ADV message.

2. The method as claimed in claim 1, wherein the m information fields include an Operator identifier (ID) field indicating an inherent ID of the BS.

3. The method as claimed in claim 1, wherein the m information fields include a neighbor BS identifier (Neighbor BS-ID) field.

4. The method as claimed in claim 1, wherein the m information fields include a handover (HO) process optimization field for indicating indispensable procedures and omissible procedures during handover to a neighbor BS.

5. The method as claimed in claim 1, wherein the m information fields include a quality of service (QoS) related field for indicating a QoS class that is supported by a neighbor BS.

6. A system for transmitting a neighbor base station advertisement (MOB_NBR-ADV) message in a broadband wireless access communication system, the system comprising:

a base station (BS) for transmitting the MOB_NBR-ADV message,

wherein the MOB_NBR-ADV message includes a first field including m bits, where m is an integer greater than or equal to 1, and

wherein when m information fields can be included in the MOB_NBR-ADV message, the m bits indicate whether any of the m information fields may be omitted from the MOB_NBR-ADV message, respectively.

7. The system as claimed in claim 6, wherein the m information fields comprise an Operator identifier (ID) field indicating an inherent ID of the BS.

8. The system as claimed in claim 6, wherein the m information fields comprise a neighbor BS identifier (Neighbor BS-ID) field.

9. The system as claimed in claim 6, wherein the m information fields comprise a handover (HO) process optimizer (HO Process Optimization) field for indicating indispensible procedures and omissible procedures during handover to a neighbor BS.

10. The system as claimed in claim 6, wherein the m information fields comprise a quality of service (QoS) related field for indicating a QoS class that is supportable by a neighbor BS.
