Method for receiving broadcast service using broadcast zone identifier in a mobile communication system
First Claim
Patent Images
1. A method for providing a broadcast service in a mobile communication system including a plurality of base stations (BSs), the method comprising the steps of:
- transmitting a broadcast zone identifier allocated to uniquely identify a broadcast zone in which a same broadcast service is provided by at least one BS to an access terminal to enable an access terminal to recognize a change in broadcast zone;
upon receiving, from the access terminal detecting a change in broadcast zone based on the broadcast zone identifier, a request for physical channel information and broadcast program information associated with a broadcast service corresponding to the broadcast zone identifier, transmitting the physical channel information and the broadcast program information to the access terminal; and
transmitting the broadcast service corresponding to the broadcast zone identifier to the access terminal;
wherein the at least one BS has a plurality of broadcast zone identifiers corresponding to a plurality of broadcast zones and the broadcast zone is associated with a connection identifier (CID) for the broadcast service.

3. A method for receiving by an access terminal a broadcast service while crossing over a boundary between a plurality of base stations (BSs) in a mobile communication system including the plurality of BSs, the method comprising the steps of:
-
receiving from a BS a broadcast zone identifier allocated to uniquely identify a broadcast zone in which a same broadcast service is provided by at least one BS including the BS; detecting whether the access terminal has departed from a previous broadcast zone by comparing received broadcast zone identifier with a previously stored broadcast zone identifier; transmitting a request for physical channel information and broadcast program information associated with a broadcast service corresponding to the broadcast zone identifier to the BS when the access terminal is detected to have departed from the previous broadcast zone; and receiving the broadcast service using the physical channel information and the broadcast program information received from the BS; wherein the at least one BS has a plurality of broadcast zone identifiers corresponding to a plurality of broadcast zones and the broadcast zone is associated with a connection identifier (CID) for the broadcast service. - View Dependent Claims (4, 5, 6, 7)

8. A method for receiving by an access terminal a broadcast service while crossing over a boundary between a plurality of base stations (BSs) in a mobile communication system including the plurality of BSs, the method comprising the steps of:
-
receiving from a base station a broadcast zone identifier list consisting of broadcast zone identifiers each allocated to uniquely identify a broadcast zone in which a same broadcast program is provided by at least one base station including the base station; detecting whether the access terminal has departed from a previous broadcast zone by comparing received broadcast zone identifier list with a previously stored broadcast zone identifier list; when the access terminal is detected to have departed from the previous broadcast zone and have entered a new broadcast zone, transmitting a request for physical channel information and broadcast program information associated with a new broadcasting service corresponding to the new broadcast zone to the base station; and receiving the new broadcast service using the physical channel information and the broadcast program information received from the base station; wherein the broadcast zone is associated with a connection identifier (CID) for the broadcast service. - View Dependent Claims (9, 10, 11, 12, 13)
