Abstract

A method for performing handover or initial accessing by a terminal includes: receiving a message including one or more of information regarding a smart meter and information regarding neighbor base stations (BSs) connected to the smart meter, the smart meter having a function for managing power, determining at least one of the neighbor BSs connected to the smart meter as a BS to be accessed; transmitting an access request message for accessing the determined BS to the smart meter, and accessing the determined BS if a response message is received from the smart meter.

Claims

1. A method for performing handover or initial accessing, the method performed by a terminal and comprising:

receiving, by the terminal, a message including one or more of information regarding a smart meter and information regarding neighbor base stations (BSs) connected to the smart meter, the smart meter having a function for managing power;

determining, by the terminal, at least one of the neighbor BSs connected to the smart Meter as a BS to be accessed;

transmitting, by the terminal, an access request message for accessing the determined BS to the smart meter; and

accessing, by the terminal, the determined BS if a response message is received from the smart meter.

2. The method of claim 1, wherein the message is received from the smart meter, the currently accessed serving BS, or a neighbor BS.

3. The method of claim 1, wherein the message is a neighbor cell information message received from the currently accessed serving BS or a system information message received from a neighbor BS.

4. The method of claim 1, wherein the receiving of the message comprises:

searching the smart meter; and

transmitting a request message with respect to the message to the searched smart meter.

5. The method of claim 1, wherein the access request message is a handover request message, and the handover request message comprises one or more of the ID of the terminal, information regarding the currently accessed BS, information regarding the determined BS, information regarding the reason of handover, and context information.

6. A method for controlling, by a smart meter which administers power, accessing of a mobile terminal, the method comprising:

transmitting a message including one or more of information regarding the smart meter and information regarding base stations (BSs) connected to the smart meter;

receiving an access request message regarding a particular BS among the BSs from the terminal;

transferring the access request message to the particular BS or the BSs which are connected to the smart meter, and

transferring the response message to the terminal if a response message is received from the particular BS or the BSs.

7. The method of claim 6, wherein the transferring of the access request message comprises:

encapsulating the access request message according to a protocol between the smart meter and the particular BS.

8. The method of claim 6, wherein the transferring of the message comprises:

receiving a request message with respect to the message; and

transmitting the message in response to the reception of the request message.

9. The method of claim 6, wherein the access request message is a handover request message, and the handover request message comprises one or more of the ID of the terminal, information regarding a BS the terminal has been currently accessed, information regarding the reason of handover, and context information.

10. A terminal comprising:

a transceiver configured to receive a message including information regarding a smart meter and information regarding neighbor BSs connected to the smart meter; and

a processor configured to determine at least one of BSs connected to the smart meter, as a BS to be accessed, based on the message,

wherein the transceiver transmits an access request message for accessing the determined BS to the smart meter, and when a response message is received from the smart meter, the transceiver accesses the determined BS.

11. The terminal of claim 10, wherein the message is received from the smart meter, the currently accessed serving BS, or a neighbor BS.

12. The terminal of claim 10, wherein the message is a neighbor cell in-formation message received from the currently accessed serving BS or a system information message received from a neighbor BS.

13. The terminal of claim 10, wherein the access request message is a handover request message, and the handover request message comprises one or more of the ID of the terminal, information regarding the currently accessed BS, information regarding the determined BS, information regarding the reason of handover, and context information.
