Example Embodiment

[0057] Example one:

[0058] In this embodiment, the call counter value returned by the wireless terminal is detected to determine whether the same wireless terminal exists. The call counter (count) value can be periodically updated through the home location register on the network side and sent to the wireless terminal within the jurisdiction. When the wireless terminal initiates a service, accepts a service, or performs location registration, the call establishment request message, Receive the latest count value saved in the service message or location registration message, and the network side compares the count value reported by the wireless terminal with the latest count value saved by the network side. If they are not the same, it indicates that the same wireless terminal exists. The service may be, but not limited to, a voice service, a short message service, or a data service. The wireless terminal will report the latest count value stored by itself in the message of initi...

Example Embodiment

[0064] Embodiment two:

[0065] In this embodiment, detecting the paging response message returned by the wireless terminal is used to determine whether the same wireless terminal exists. That is, the MSC judges whether the called party user has a cloned wireless terminal according to the received multiple paging response messages. Fig. 4 is a flowchart of a method for detecting the same wireless terminal according to a paging response message according to this embodiment. The method specifically includes the following steps:

[0066] Step 401: The MSC sends a paging message to the base station subsystem (BSS) to page the called user.

[0067] Step 402: The BSS pages the wireless terminal through the paging channel on the air interface. Since the international mobile subscriber identification number (IMSI) and electronic serial number (ESN) of the cloned wireless terminal user are the same as the host, the cloned wireless terminal user can also receive and process paging messages ...

Example Embodiment

[0072] Embodiment three:

[0073] In this embodiment, a call request message sent by the wireless terminal is detected to determine whether the same wireless terminal exists. This embodiment is to detect whether there is a cloned wireless terminal for the calling party user. First, on the network side, the status information of the wireless terminal within its own jurisdiction is stored, and the status information includes whether the wireless terminal is in a talking state or in an idle state at a certain moment. After the call connection between the calling party and the called party is established, the wireless terminals of both the calling party and the called party are in the conversation state during the conversation. If the MSC receives the same IMSI as the calling wireless terminal during this process, The call request of another wireless terminal is sent only when the user's wireless terminal is in a non-talking state. This indicates that the same wireless terminal must e...

Abstract

This invention discloses one method to test same wireless terminal, which comprises the following steps: network side receives wireless terminal message or message with signal value; if there received collision message or signal values, that presents wireless terminal same wit the wireless terminal. This invention also discloses one device, which comprises the following parts: message reverie module to receive wireless terminal message or signal value and to send them to judge module; test and judge module to test and judge whether there is collision and whether there is wireless terminal same to wireless terminal.

Description

technical field [0001] The invention relates to identification technology of wireless terminals, in particular to a method and device for detecting identical wireless terminals. Background technique [0002] At present, with the rapid development of communication technology, the convenience of mobile terminals has brought great convenience to people's life, and more and more users use mobile terminals for communication. However, there is now a phenomenon that mobile terminals are cloned. For example, duplicators for Subscriber Identity Module (SIM) cards in the Global System for Mobile Communications (GSM) have appeared, and multiple identical SIM cards with the same number can be duplicated using this duplicator. In addition, duplication of User Identity Module (UIM) cards in Code Division Multiple Access (CDMA) systems has also occurred. The mobile terminal installed with the copied SIM card or UIM card will become the clone mobile terminal of the mobile terminal with th...
