Abstract

The present invention relates to a method, a base station, and a terminal for obtaining a moving speed of a mobile terminal. A moving speed of a mobile terminal is obtained by obtaining a distance estimation parameter and using the distance estimation parameter, or a moving speed of a mobile terminal is obtained according to information reported by the mobile terminal, or a moving speed of a mobile terminal is received from another base station, so as to enable a base station to learn the moving speed of the mobile terminal and therefore avoid the problem of call drop caused by slow handover because of a fast moving speed of a mobile terminal.

Claims

1. A method for obtaining a moving speed of a mobile terminal, comprising:

establishing a signaling connection with a mobile terminal; and

receiving information reported by the mobile terminal through the signaling connection established with the mobile terminal; and

obtaining a moving speed of the mobile terminal according to the received information.

2. The method for obtaining a moving speed of a mobile terminal according to claim 1, wherein the receiving information reported by the mobile terminal through the signaling connection established with the mobile terminal comprises:

receiving evaluation of a speed in an idle state of the mobile terminal.

3. The method for obtaining a moving speed of a mobile terminal according to claim 1, wherein the receiving information reported by the mobile terminal through the signaling connection established with the mobile terminal comprises:

through the signaling connection with the mobile terminal, receiving at least one of information;

cell type information, a cell identity, and the duration of staying in each cell.

4. The method for obtaining a moving speed of a mobile terminal according to claim 1, further comprising:

sending the information reported by the mobile terminal to a neighbor base station.

5. The method for obtaining a moving speed of a mobile terminal according to claim 1, further comprising:

performing radio resource management according to the obtained moving speed.

6. A method for a base station to obtain a moving speed of a mobile terminal, comprising:

establishing a signaling connection with a serving base station; and

reporting information to the serving base station through the signaling connection established with the serving base station, so as to enable the serving base station to obtain a moving speed of a mobile terminal according to the information.

7. The method for a base station to obtain a moving speed of a mobile terminal according to claim 6, wherein the reporting information to the serving base station through the signaling connection established with the serving base station comprises:

reporting evaluation of a speed in an idle state of the mobile terminal to the serving base station through the signaling connection with the serving base station.

8. The method for a base station to obtain a moving speed of a mobile terminal according to claim 6, wherein the reporting information to the serving base station through the signaling connection established with the serving base station comprises:
