Method of communicating neighbor base station information
First Claim
1. A method of communicating neighbor base station information in a mobile communication system, the method comprising:
- transmitting, from a management entity to a neighbor base station, a request message that originates at a serving base station for requesting the neighbor base station information;
receiving, by the management entity from the neighbor base station, a first response message including the neighbor base station information, wherein the neighbor base station information includes physical channel information for connecting to the neighbor base station, parameters for an uplink channel descriptor (UCD), and parameters for a downlink channel descriptor (DCD);
transmitting, from management entity to a serving base station, a first message that originates at the management entity and includes the neighbor base station information;
broadcasting at a first periodic interval a first neighbor advertisement message including the neighbor base station information from the serving base station to all mobile subscriber stations existing within a corresponding cell of the serving base station;
receiving, by the management entity from the neighbor base station, a second response message including updated neighbor base station information at a second periodic interval without requesting the neighbor base station information from the management entity when there is a change in the neighbor base station information, wherein the updated neighbor base station information includes at least updated physical channel information for connecting to the neighbor base station, updated parameters for a UCD, or updated parameters for a DCD;
transmitting, from the management entity to the serving base station, a second message that originates at the management entity and includes the updated neighbor base station information; and
broadcasting a second neighbor advertisement message following the first periodic interval from the serving base station to all mobile subscriber stations existing within the corresponding cell of the serving base station, wherein the second neighbor advertisement message includes the updated neighbor base station information.

Abstract
A method uses inter-base station control messages to provide neighbor base station information to mobile subscriber stations in a mobile communication system. The method includes obtaining, at a serving base station, physical channel information of neighbor base stations over a backbone network via, either directly or via a server; periodically transmitting the obtained physical channel information from the serving base station to a mobile subscriber station connected to the serving base station; and measuring, based on the updated physical channel information, signal quality of the at least one neighbor base station at the mobile subscriber station. Thus, the serving base station receives from the neighbor base stations the inter-base station control messages containing the neighbor base station information, updates the information, and provides the updated information to the corresponding mobile subscriber station(s), to be used for a specific purpose such as handover or network entry.

11. A mobile communication system for communicating neighbor base station information, the system comprising:
-
a management entity; and a serving base station, wherein the management entity is configured to; transmit, to a neighbor base station, a request message that originates at a serving base station for requesting the neighbor base station information, receive, from the neighbor base station, a first response message including the neighbor base station information, wherein the neighbor base station information includes physical channel information for connecting to the neighbor base station, parameters for an uplink channel descriptor (UCD), and parameters for a downlink channel descriptor (DCD), transmit, to a serving base station, a first message that originates at the management entity and includes the neighbor base station information, receive, from the neighbor base station, a second response message including updated neighbor base station information at a second periodic interval without requesting the neighbor base station information from the management entity when there is a change in the neighbor base station information, wherein the updated neighbor base station information includes at least updated physical channel information for connecting to the neighbor base station, updated parameters for an UCD, or updated parameters for a DCD, and transmit, to the serving base station, a second message that originates at the management entity and includes updated neighbor base station information, wherein the serving base station is configured to; broadcast at a first periodic interval a first neighbor advertisement message including the neighbor base station information from serving base station to all mobile subscriber stations existing within a corresponding cell of the serving base station, and broadcast a second neighbor advertisement message following the first periodic interval from the serving base station to all mobile subscriber stations existing within the corresponding cell of the serving base station, wherein the second neighbor advertisement message includes the updated neighbor base station information. - View Dependent Claims (12, 13, 14, 15)
