Abstract

An apparatus for supporting a mobile station (MS) to perform a communication using a plurality of networks in a mobile communication system and method thereof are disclosed. According to the present invention, a serving base station (BS) of the MS receives information on at least one heterogeneous network from a BS of each of the at least one heterogeneous network. The serving BS of the MS selects at least one of a heterogeneous network to be allocated to the MS and a channel of the heterogeneous network based on the received information on the at least one heterogeneous network. And, the serving BS of the MS transmits an information on the selected heterogeneous network to the MS.

Claims

1. A method of supporting a mobile station (MS) to perform a communication using a plurality of networks in a mobile communication system, the method comprising:

receiving, at a serving base station (BS) of the MS, information on at least one heterogeneous network from a base station of each of the at least one heterogeneous network;

determining, at the serving BS, a heterogeneous network to be allocated to the MS and a channel of the heterogeneous network based on the information on the at least one heterogeneous network,

wherein the channel of the heterogeneous network to be allocated to the MS is allocated in accordance with a predetermined rule among all channels of the heterogeneous network, and

wherein the predetermined rule is determined using an MS identifier (ID) and a channel hopping sequence; and

transmitting, at the serving BS, information on the determined heterogeneous network to the MS.

2. The method of claim 1, further comprising:

transmitting, at the serving BS, a request for the information on the heterogeneous network to the base station of each of the at least one heterogeneous network.

3. The method of claim 1, further comprising:

transmitting, at the serving BS, a request for a channel status measurement for the channel of the allocated heterogeneous network to MS;

receiving, at the serving BS, a channel status measurement result for the channel of the allocated heterogeneous network from the MS; and

allocating, at the serving BS, a specific channel having a best channel status to the MS based on the channel status measurement result.

4. The method of claim 1, wherein the information on the at least one heterogeneous network includes information on the channel status between the MS and each of the at least one heterogeneous network.

5. The method of claim 4, wherein the information on the channel status includes at least one of an interference level, a signal to interference plus noise ratio (SINR), a carrier to interference plus noise ratio, a received signal strength indicator, a beam pattern and a precoding matrix index (PMI).

6. The method of claim 1, wherein the channel of the heterogeneous network comprises a plurality of channels.

7. A base station (BS) for supporting a mobile station (MS) to perform a communication using a plurality of networks in a mobile communication system, the method comprising:

a receiving module configured to receive information on at least one heterogeneous network corresponding to a heterogeneous for the MS from the BS of each of the at least one heterogeneous network;

a processor configured to determine a heterogeneous network to be allocated to the mobile station and a channel of the heterogeneous network based on the received information on the at least one heterogeneous network,

wherein the channel of the heterogeneous network to be allocated to the MS is allocated in accordance with a predetermined rule among all channels of the heterogeneous network, and

wherein the predetermined rule is determined using an MS identifies (ID) and a channel hopping sequence; and

a transmitting module configured to transmit information on the determined heterogeneous network to the MS.

8. The BS of claim 7, further comprising:

a transmitting module configured to transmit a signal for requesting the information on the heterogeneous network to the BS of each of the at least one heterogeneous network.

9. The BS of claim 7, further comprising:

a transmitting module configured to transmit a signal for requesting a channel status measurement for the channel of the allocated heterogeneous network to the MS;

a receiving module configured to receive a channel status measurement

result for the channel of the allocated heterogeneous network from the MS; and

a processor configured to allocate a specific channel having a best channel status to the MS based on the channel status measurement result.

10. The BS of claim 7, wherein the information on the at least one heterogeneous network includes information on the channel status between the MS and each of the at least one heterogeneous network.

11. The BS of claim 10, wherein the information on the channel status contains at least one of an interference level, a signal to interference plus noise ratio (SINR), a carrier to interference plus noise ratio, a received signal strength indicator, a beam pattern and a precoding matrix index (PMI).

12. The BS of claim 7, wherein the channel of the heterogeneous network comprises a plurality of channels.
