Problems solved by technology
When the terminal switches from the macro base station to the home gateway base station, there are two situations. The first is that the terminal detects that the signal quality of the macro base station providing services for it is very weak, while the signal quality of the home gateway base station is strong. Handover request, this is the traditional handover method; the second is that the terminal switches from the macro base station to the home gateway base station, and the signals of the macro base station and the home gateway base station providing services for it are both strong. In this case, the terminal wants to Switching to the home gateway base station, the traditional switching method will not be realized

Embodiment Construction
[0027] The present invention will be further described below in conjunction with the accompanying drawings.
[0028] figure 1 It has been described in the background technology, and will not be repeated here.
[0029] refer to image 3 , a method for a Wimax terminal to perform base station switching, comprising the following steps:
[0030] 3.1 When the terminal enters the service range of the home gateway base station and wants the home gateway base station to provide services for it, the terminal triggers a request to switch from the macro base station to the home gateway base station through its interface, that is, the terminal sends a scan request to the macro base station;
[0031] 3.2-3.3 After receiving the scanning request, the macro base station sends an association request to the home gateway base station through the access gateway, that is, the macro base station sends an association request to the access gateway, and the access gateway forwards the association r...

The present invention discloses a method of the base station switching of a Winax terminal, which includes four steps. Firstly, the terminal is correlated with a home gateway base station via a macrobase station and an access gateway to realize the uplink synchronization; secondly, the macro base station compares the information of the home gateway base station with the stored information of a terminal-authorized home gateway base station, if the home gateway base station is the terminal-authorized home gateway base station and the signal quality meets the service requirement of the terminal,then the macro base station sends a base station switching request to the home gateway base station via the access gateway, otherwise the home gateway base station switching is not carried out, and the flow of the home gateway base station switching is terminated; thirdly, the home gateway base station establishes a data channel with the access gateway and sends a base station switching responseto the terminal ordinally via the access gateway and the macro base station; finally, the terminal sends a switching indication to the macro base station and accesses the home gateway base station, and the flow of the base station switching is finished. The present invention realizes that a terminal switches from a macro base station to a home gateway base station under the condition of the equalsignal quality.
Description
technical field [0001] The invention relates to a method for a terminal to perform base station switching, in particular to a method for a Wimax (World Interoperability for Microwave Access, World Interoperability for Microwave Access) terminal to perform base station switching. Background technique [0002] Currently, in the air interface protocol IEEE802.16e of the broadband wireless access system, handover messages carry information such as noise ratio, signal strength or delay information, which are necessary conditions for the base station side to judge whether handover is necessary for the terminal. However, some operators attract users to use WiMax network by setting up home gateway base stations, such as figure 1 As shown, each circle represents the service range of each base station, and a large number of home gateway base stations are deployed under the coverage of the macro base station. Among them, the home gateway base station adopts a different frequency networ...
