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 present invention provides a method and system for switching. Upon receiving the failure information and determining the failure information contains status information of target base station, the source switching network element pauses in requesting for switching. Using the method of the present invention, the source switching network element learns that the cause of the switching failure is the status of the target base station, and thereby takes the appropriate measurement for the failure cause: pausing the switching request, thus avoiding repeated invalid switching, reducing the frequency of invalid switching launched by the source switch network element, and consequently improving the performance of network 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)NBAN, Home(e)NodeBAccessNetwork, referred to as the home base station access network in ...
