Abstract: The present invention takes the advantage of the WLAN resources in hotspots for voice and data connections and enables seamless handover between WWAN and WLAN and vice versa. This allows two users in the hotspots to communicate with each other by making a voice over IP (VoIP) or video call, 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 has wireless wide area network (WWAN) and wireless local area network (WLAN) interfaces. The 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.

Abstract: The present invention provides a wireless network system that enables direct wireless delivery of a multimedia message from a first MMS user agent to a second MMS user agent. In accordance with one embodiment of the invention, the wireless network system includes a MMS server that receives, from the first MMS user agent, a request to send a multimedia message to the second MMS user agent. The request includes an identification (ID) number of the second MMS user agent. From a core network, for example, the MMS server obtains an Internet address of the second MMS user agent based on the ID number of the second MMS user agent, if the ID number is not an Internet address of the second MMS user agent. Then the MMS server forwards the Internet address to the first MMS user agent to enable the first MMS user agent to wirelessly deliver the multimedia message directly to the second MMS user agent using the Internet address.

The method comprises: the terminal (10) receiving a notification including address information of the multimedia message from the transmitter (40); the terminal (10) detecting a further terminal (20) capable of receiving at least part of the multimedia message; the terminal (10) sending address information from the further terminal (20) to the transmitter (40) or vice versa; the further terminal (20) receiving the multimedia message on the basis of the address information. In this way, the multimedia message is communicated quickly and securely from a transmitter (40) via a terminal (10) to a further terminal (20).

Abstract: A method is proposed for a mobile terminal in mobile communication systems to transfer non-speech data in voice channel, comprising steps of: encapsulating the non-speech data to be sent to another mobile terminal into IBD frames; storing said IBD frames in a buffer; detecting whether a speech burst sent to said another mobile terminal is over; checking whether there is non-speech data to be sent to said another mobile terminal if detecting that said speech burst is over; sending at least one non-speech data to said another mobile terminal via voice channel if there is non-speech data to be sent. By modifying the SID frame and silence speech frame, this method realizes transmission of non-speech via voice channel rather than via dedicated data channel, so as to save radio resources of the system.

Abstract: The invention allows a portion of a multimedia message, usually the beginning part of the message to be delivered to and stored on a mobile terminal beforehand. When a user wants to view the message, the portion of the message stored locally will be played back immediately, while at the same time a user agent residing in the mobile terminal will contact a media server for the remaining contents using the streaming technology. This would give the user an impression that the whole message is stored locally since there is nearly no noticeable delay in the playback, thus providing a much better user experience. The partial contents down-loaded can be a portion of the whole multimedia message, or an muntrelated rich-media message provided by a third party as an advertisement. In this way, the usage of the local storage space on the mobile terminal will be much more efficient.

Abstract: A method for addressing and locating WLAN communication node is disclosed in the present invention. The GSM or CDMA, which is characterized in broad coverage, the steadiest performance, and the most mature technology, is employed to confirm the subscribers' IP address.
