    • The present invention takes the advantage of the wireless local area network (WLAN) resources in hotspots for voice and data connections and enables seamless handover between wireless wide area network (WWAN) and WLAN and vice versa, thus achieving cost savings for the end users and WWAN resources savings for the wireless operators. According to one embodiment of the invention, a mobile terminal having WWAN and WLAN interfaces establishes a WWAN call with a called mobile terminal via a WWAN. If a WLAN is present, the mobile terminal sends a handover request together with its network address to the called mobile terminal, using a short message service (SMS) technique or a watermarking technique, for initiating a WLAN call with the called mobile terminal via a WLAN. After the WLAN call is established with the called mobile terminal, the mobile terminal releases the WWAN call.
    • 本发明利用无线局域网(WLAN)资源在热点进行语音和数据连接,并实现无线广域网(WWAN)与WLAN之间的无缝切换,反之亦然,从而实现最终用户的成本节约, WWAN资源节省无线运营商。 根据本发明的一个实施例,具有WWAN和WLAN接口的移动终端通过WWAN与被叫移动终端建立WWAN呼叫。 如果存在WLAN,则移动终端使用短消息服务(SMS)技术或水印技术将与其网络地址一起的切换请求发送到被叫移动终端,以通过经由呼叫的移动终端发起WLAN呼叫 WLAN。 在与被叫移动终端建立WLAN呼叫之后,移动终端释放WWAN呼叫。
