Method, device and system for realizing wireless network access

Abstract

The embodiment of the invention discloses a method, device and system for realizing wireless network access. The method comprises the steps of: receiving a cellular network data service request initiated by a mobile terminal, judging whether a wireless local area network (WLAN) exists in a coverage range of a cellular network cell in which the mobile terminal is arranged, if so, judging whether distribution is carried out through the WLAN, if the distribution is carried out through the WLAN, obtaining a list of wireless local area network access points (AP) allowed to be accessed in the coverage range of the cellular network cell where the mobile terminal is, informing the mobile terminal of the list of the APs allowed to be accessed. By adopting the method, the device and the system provided by the embodiment of the invention, data services in a hot spot area can be distributed, and further utilization rate of the WLAN is increased, and service and signaling loads of a cellular network are reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for realizing wireless network access. Background technique [0002] With the explosive development of communication technology and data services, the business and signaling loads in hotspot areas of wireless cellular networks are very heavy, and resources are seriously insufficient; in view of this, the currently commonly used method is to deploy wireless local area network access points (Wireless Local Area Network Access Points) in hotspot areas. Local Area Networks Access Point, WLAN AP), used to offload cellular network data services and reduce cellular network traffic and signaling load. [0003] However, although most mobile terminals support wireless cellular network access at present, due to the limited power of mobile terminals and the continuous scanning of WLAN networks by mobile terminals will cause a sharp increase in power...

AI Technical Summary

Problems solved by technology

[0003] However, although most mobile terminals support wireless cellular network access at present, due to the limited power of mobile terminals and the continuous scanning of WLAN networks by mobile terminals will cause a sharp increase in power consumption, in order to increase the standby time, the WLAN networks of most mobile terminals are currently automatically activated. Scanning functions are artificially or passively turned off

In this case, if the WLAN automatic scanning function of the mobile terminal is turned off, even if the mobile terminal is in the area covered by the WLAN network, it cannot automatically receive the WLAN network notification; It does not know whether there is WLAN network coverage in the current area, so it often does not manually turn on the WLAN network scanning function to try to search for WLAN networks, but directly chooses to use the wireless cellular network to access data services, which will lead to WLAN APs have been deployed in data service hotspot areas, but in fact, because users do not know which areas are covered by WLAN networks, the actual utilization rate of WLAN networks is low, and it is difficult to distribute data in cellular network hotspot areas through WLAN network access points business objectives, resulting in high traffic and signaling loads on the cellular network
