Communication method and apparatus using heterogeneous neighbor base station information in a broadband wireless access communication system
First Claim
1. A communication method using a neighbor Base Station (BS) information in a broadband wireless access communication system, the method comprising the steps of:
- gathering information in a serving BS about neighbor BSs;
determining if heterogeneous communication systems exist from the gathered information;
if the heterogeneous communication systems exist, including, in the serving BS, the information about the heterogeneous communication systems in a MOB_NBR-ADV (Mobile_Neighbor-Advertisement) message;
broadcasting the MOB_NBR-ADV message to a Mobile Subscriber Station (MSS); and
if the MOB_NBR-ADV message is received in the MSS from the serving BS, identifying if the heterogeneous communication systems exist from in the MOB_NBR-ADV message.

Abstract
A broadband wireless access communication system including a serving BS that periodically broadcasts an MOB_NBR-ADV message to an MS, and different kinds of heterogeneous networks. In order to communicate using the neighbor Base Station (BS) information, the serving BS gathers information about neighbor BSs and determines if heterogeneous communication systems exist using the gathered information. If the heterogeneous communication systems exist, the serving BS includes the information about the heterogeneous communication systems in the MOB_NBR-ADV message and broadcasts the MOB_NBR-ADV message to an MSS. If the MOB_NBR-ADV message is received from the serving BS, the MSS identifies if the heterogeneous communication systems exist using the MOB_NBR-ADV message.

8. A method for configuring a Mobile_Neighbor-Advertisement (MOB_NBR-ADV) message that is periodically broadcast to a Mobile Subscriber Station (MSS), in a serving Base Station (BS) of a broadband wireless access communication system, the method comprising the steps of:
-
gathering information about neighbor BSs;
determining if heterogeneous BSs exist from among the neighbor BS information; and
allocating identification information that represents if the heterogeneous BSs exist to a prescribed field, according to a result of the determining step. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. An apparatus for communicating through Mobile_Neighbor-Advertisement (MOB_NBR-ADV) message transmission/reception in a broadband wireless access communication system including heterogeneous communication systems, the apparatus comprising:
-
a serving base station (BS) for gathering information about neighbor BSs, determining if heterogeneous BSs exist from among neighbor BSs, allocating identification information that indicates if the heterogeneous BSs exist to a prescribed field according to a result of the determining step to configure the MOB_NBR-ADV message, and broadcasting the MOB_NBR-ADV message, to which the prescribed field is added; and
a mobile subscriber station (MSS) for checking an information field for the heterogeneous BSs included in the MOB_NBR-ADV message, if receiving the MOB_NBR-ADV message from the serving BS, determining if a heterogeneous BS, to which the MSS can access, exists in a cell of the BS, according to a value set in the information field for the heterogeneous BSs, and performing one of power control thereof and an access to the heterogeneous BS, based on whether the heterogeneous BS that the MSS can access exists in the cell of the BS. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A method for communicating between an MSS (mobile subscriber station) and a heterogeneous network in a communication system in which a serving BS (base station) periodically broadcasting an Mobile_Neighbor-Advertisement (MOB_NBR-ADV) message coexists with different kind of heterogeneous networks, the method comprising the steps of:
-
if the MSS receives the MOB_NBR-ADV message from the serving BS, checking an information field for heterogeneous BSs included in the MOB_NBR-ADV message; and
performing operations corresponding to if a heterogeneous BS, to which the MSS can access, exists in a cell of the serving BS, according to a value set in the information field for the heterogeneous BSs. - View Dependent Claims (32, 33)
