Problems solved by technology

[0011] However, in some cases, WWAN systems such as GSM, GPRS or 3G provide a method called Calling Line Identification Restriction (CLIR) and Connecting Line Identification Restriction (COLR) to protect the privacy of the calling party. mechanism, or the WWAN system can also provide the called party with identification information different from the calling party's identification information, such as a false phone number, so that the called party cannot obtain the calling party's identification information
In addition, when interconnecting between networks belonging to different operators, or between networks in different regions, it is also possible not to provide the calling party's phone number to the called party or to display only a false phone number
For the above two cases, in the handover process shown in Figure 2A and Figure 2B, the UE receiving the WWAN call cannot confirm the identity of the UE sending the WWAN call based on information such as the phone number in the WWAN call, resulting in handover failure or open the possibility for a possible third party to intercept or eavesdrop on the call

[0033] Fig. 3 shows an information flow diagram of identifying the calling UE identity of a WWAN handover call during the handover process from WLAN to WWAN according to the first embodiment of the present invention.

[0034] In the information flow shown in FIG. 3 , if the calling UE of the WWAN switching call determines or agrees to switch from WLAN to WWAN, the calling UE sends the WWAN switching call to the called UE via the WWAN interface. Then, if the calling UE receives the ringback tone sent by the WWAN network, it sends confirmation information to the called UE via the WLAN interface to inform the called UE that the WWAN handover call it just received comes from the calling UE. The process is as follows.

[0035] Similar to FIG. 2A and FIG. 2B, in the case of communicating with a counterpart UE via a WLAN interface (step S30), the calling UE of the WWAN handover call first sends a WWAN handover call to the called UE via the WWAN interface (step S130a). FIG. 3 specifi...

[0039] Fig. 4 shows an information flow diagram of identifying the identity of the calling UE of the WWAN handover call during the handover process from WLAN to WWAN according to the second embodiment of the present invention.

[0040] In the information flow shown in Figure 4, if the calling UE of the WWAN handover call determines or agrees to switch from WLAN to WWAN, the calling UE can first send the WWAN handover call to the called UE through the WWAN interface, and the called UE receives the WWAN handover call. After the call is handed over to the WWAN, the confirmation information of the WWAN handover call is obtained from the calling UE through the WLAN interface through an inquiry response. The specific process is as follows.

[0041] Similar to the first embodiment, in the case of communicating with the counterpart UE via the WLAN interface (step S30), the calling UE first sends a WWAN handover call to the called UE via the WWAN interface (step S130a, the specific step...

[0046] Fig. 5 shows an information flow diagram of identifying the identity of the calling UE of the WWAN handover call during the handover process from WLAN to WWAN according to the third embodiment of the present invention.

[0047] In the handover process shown in Figure 5, if the calling UE of the WWAN handover call confirms or agrees to handover from WLAN to WWAN, the calling UE can send the WWAN handover call to the called UE via the WLAN interface before sending the WWAN handover call to the called UE. The UE sends information to inform the called UE that the WWAN handover call to be received is from the calling UE, and the specific process is as follows.

[0048] As shown in Figure 5, in the case of communicating with the counterpart UE via the WLAN interface (step S30), the calling UE of the WWAN handover call sends the WWAN call to the called UE via the WLAN interface before sending the WWAN handover call via the WWAN interface. Switch call request information (step ...

Abstract

The invention provides a method and a device for identify identification executed in the first mobile terminal for switching from the present serving network to the target network. The method comprises the steps: obtaining the switch state information of the communicated second mobile terminal; transmitting the identify information to the second mobile terminal according to the switch state information to ensure the second mobile terminal identifies the identify. Wherein the switch state information and the identify confirming information are transmitted by different networks. By adopting the method and the device, the switch process between two wireless networks still can be ensured under the condition that the main calling identification information of the switch calling is not provided.

Description

technical field [0001] The present invention relates to a wireless communication system, in particular to a method and device for identity identification in the handover process between different wireless communication networks. technical background [0002] With the development of wireless communication technology, various types of wireless networks have emerged, and various wireless networks can provide distinctive services. [0003] For example, wireless local area networks (WLANs) usually deployed in so-called hotspots such as airports and hotels can provide people with data services, voice services over IP (VoIP), and the like. People use a wireless terminal, such as a mobile phone or a notebook computer, to access network resources in a WLAN and resources in a network connected thereto (such as the Internet, etc.) through wireless access. Moreover, multimedia services such as video calls can also be enjoyed. In addition, wireless networks such as Bluetooth, WiMAX (Wo...
