Method, system of performing hand over without adding information of femto base station to peripheral base station announcement information in a wireless communication network

摘要

A communication system in which a primary base station or a secondary base station communicates with a mobile terminal. The primary base station sends the mobile terminal and the secondary base station an announcement signal which includes identification information for identifying a cell of the primary base station. When receiving the announcement signal, the secondary base station sends the mobile terminal a pseudo announcement signal which includes the identification information and adjacent cell information which includes information for a cell of the secondary base station. When receiving the announcement signal and the pseudo announcement signal, the mobile terminal compares a reception power of the signal received from the primary base station with that of the signal received from the secondary base station, and performs communication with one of the base stations which has higher power.

主权项

1. A femto base station in a wireless communication system that includes a mobile terminal, a base station having a first cell, and the femto base station having a second cell,
wherein the femto base station is configured to send a signal using a first frequency used in the first cell to which the mobile terminal is connected, wherein the signal enables the mobile terminal to connect to the second cell, and wherein the second cell is a femtocell, and wherein the femto base station is configured to communicate with the mobile terminal, which is connected to the second cell, by using a second frequency that differs from the first frequency.
