Problems solved by technology

At this time, most of the terminals in the connected state in the source cell have services. When handover occurs to the home base station, the home base station cannot provide corresponding services, thus causing handover failure.
That is to say, in the prior art, the handover judgment is only made based on the measurement of the terminal, and the source base station may initiate an invalid handover to the home base station in the TRAINNING state

Embodiment Construction

[0050] image 3 The flow chart of the method for realizing switching for the present invention, as image 3 shown, including the following steps:

[0051] Step 300: When the handover fails, the target handover network element notifies the source handover network element of the failure information.

[0052] This step further includes: the target handover network element notifies the core network element of the failure information, and the core network element notifies the source handover network element of the obtained failure information.

[0053] The failure information may be carried in a handover failure response message, and the handover failure response message may be: a handover failure message, or a handover preparation failure message, or a relocation failure message, or a relocation preparation failure message.

[0054] It should be noted that, in this step, the failure information received by the source switching network element may also be directly notified by the...

Abstract

The invention discloses a method and a system for realizing switching. The method comprises the following steps that: a source switching network element receives failure information, determines that the state information of a target base station is included in the failure information, and temporarily stops a switching request. By adoption of the method, the source switching network element determines that the switching fails due to the state of the target base station so as to perform correct processing, namely temporary stopping of the switching request, on the failure reason. Therefore, the repeated generation of invalid switching is avoided, and the frequency of the invalid switching which is initiated by the source switching network element is reduced, so that the network performance is improved.

Description

technical field [0001] The present invention relates to home base station technology, especially a method and system for realizing handover. Background technique [0002] With the development of wireless communication technology, the concept of home base station is introduced into the wireless communication system. Home base stations are small, low-power base stations that are deployed in indoor places such as homes and offices. The main function is to provide users with higher service rates and reduce the cost of using high-speed services. Insufficient coverage of conventional cellular wireless communication systems. The advantages of femtocells are affordable, convenient, low power output, plug and play, etc. [0003] Such as figure 1 , figure 2 As shown, the home base station user is connected to the core network network through the home (evolved) base station access network (H(e)NB AN, Home(e)NodeB Access Network, referred to as the home base station access network ...
