Problems solved by technology

[0004] However, on the one hand, in the above-mentioned passive scanning and active scanning, the scanning is performed blindly, because the STA does not know in which channel there will be an AP, so it is not conducive to terminal power saving and wasteful On the other hand, during the active scanning process, although some APs have responded, the SSID carried in the probe request frame sent by the STA is a wildcard, which may cause the STA to receive response signaling from many APs, and the The possibility of conflict is greatly increased

Abstract

The invention provides a communication device which comprises a data processing module which generates an initial network access message frame, wherein the initial network access message frame at least comprises a destination address which is a multicast address which is a uniformly distributed only address corresponding to a receiving side of the initial network access message frame; and a data exchange module which sends the initial network access message frame. The invention also provides a wireless communication method. Through the technical scheme of the invention, in an active scanning process that the communication device executes network switching, the sending target of the message frame is accurate as much as possible, thus the waste of electricity caused by blind sending is avoided, and the message conflict caused by the reception of too many response message frames at the same time is avoided.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular, to a communication device and a wireless communication method. Background technique [0002] Interworking between WLAN networks and 3GPP networks has now become a popular research direction. In 802.11, the 802.11u standard has formulated the ANQP (Access Network Query Protocol, Access Network Query Protocol) protocol to specify WLAN networks and 3GPP networks. Interworking mechanism between. [0003] The process of STA (terminal) switching from 3GPP network to WLAN network mainly includes: STA scans BSS (Basis Service Set, Basic Service Set), this process is long, because the principle of WLAN network is to listen first and then send, so the STA scans The process is first passive scanning, that is, listening to the beacon (Beacon) frame broadcast by the AP (Access Point, access point), and this process may be carried out in 13 channels; if the AP cannot be det...
