Problems solved by technology

[0004] However, because mobile terminals of different manufacturers may have custom standard handover thresholds, and it is difficult to unify them. After the signal quality of the current AP is poor to a certain extent, it is no longer able to provide services to users normally, but it may not reach a certain level. The handover threshold of the mobile terminal, so that the mobile terminal cannot be handed over to the target AP, thus affecting the user's service quality
Moreover, when the signal quality is poor to a certain extent, it will lead to a large amount of retransmission of business data, thereby reducing the utilization rate of wireless bandwidth

Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] The method provided by the present invention mainly includes: the network side acquires the signal quality information of the mobile terminal detected by the current AP and the target AP; judging that the signal quality of the mobile terminal detected by the current AP is lower than that of the mobile terminal detected by the target AP Whether the value of the signal quality of the signal reaches the set threshold, and if yes, the mobile terminal is triggered to switch to the target AP.

[0031] The above method can be used in the centralized WLAN network architecture of thin APs, that is, the AC manages each AP. At this time, the acquisition and trigger operations in the above method are performed by the AC in the WLAN network; it can also ...

Abstract

The invention discloses a roaming switching and trigger method, an access control (AC) and an access point (AP), wherein the method comprises: the present AP of a mobile terminal access and signal quality information of a mobile terminal detected by the target AP are acquired; the difference value of which the signal quality of the mobile terminal detected by the present AP is lower than that detected by the target AP is judged to reach the set threshold value or not, if the difference value reaches the set threshold value, the mobile terminal is triggered to switch to target AP. The method of the invention ensures the service quality of users and increases the utilization rate of wireless broad band.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a roaming handover triggering method, an access controller and an access point. Background technique [0002] With the development of wireless local area network (WLAN, Wireless Local Area Network) technology, the centralized management of WLAN has been applied more and more. A centrally managed WLAN is mainly composed of an access point (AP, Access Point) and an access controller (AC, Access Controller). The AC manages multiple APs to jointly provide WLAN access services. A mobile terminal can access a WLAN within the coverage of any AP. [0003] When the mobile terminal roams, it will roam from the coverage area of ​​one AP to the coverage area of ​​another AP. For the convenience of description, the other AP is referred to as a target AP. During roaming, the signal quality of the currently accessed AP will gradually decrease, while the signal quality of the targ...
