In the existing call testing method, there is a need to test the call function (ie, network compatibility) of the calling device 20 or the called device 40 when the SIP message sent by the network 30 is abnormal. However, when the existing call test method tests the call function capability (i.e., network compatibility), the abnormality of the SIP message sent by the network 30 cannot be known in advance, so the current call test cannot accurately test the calling device. 20 or the network compatibility of the called device 40 is tested.

The identity information of the SIM card of the terminal 20' is deleted from the user list, wherein the identity information of all SIM cards authorized to access the IMS network server are recorded in the legal user list. In an embodiment of the present application, if the identity information of the SIM card is stored in the legal user list of the IMS network server, the terminal 20' inserted into the SIM card can access the IMS network server of the network 30; if the identity information of the SIM card After the information is deleted from the legal user list of the IMS network server, the terminal 20 ′ inserted with the SIM card cannot access the IMS network server of the network 30 .

In an embodiment of the present application, the identity information of the SIM card includes an International Mobile Subscriber Identification Number (IMSI). For example, the specific content of the network 30 setting that the SIM card of the terminal 20' does not access the IMS network server of the network 30 is illustrated below by taking the terminal 20' as a mobile phone as an example. The network 30 obtains the IMSI number of the SIM card of the mobile phone through the base station 50, and deletes the IMSI number of the SIM card of the terminal 20' from the legal user list stored in the MS network server, so that the mobile phone cannot access the IMS network server of the network 30. However, at this moment, the mobile phone can still access the EPC (Evolved Packet Core Network) of the network 30, and can access the PGW (Packet Data Network Gateway), SGW (Serving Gateway) and MME (Mobility Management Entity) of the EPC.

During the interaction process of the SIP message between the control device 60 and the terminal 20', since the SIM card of the terminal 20' is not connected to the IMS network server of the network 30 in step S41, the network 30 cannot transmit the SIP message sent by the terminal 20'. The message is sent to the IMS network server, but the SIP message is sent to the control device 60 by routing.

In an embodiment of the present application, generating the SIP message of network abnormality through the Python tool, and sending the SIP message of network abnormality to the terminal 20' includes: the control device 60 generates the SIP message of network abnormality through the Python tool, and sends the SIP message of network abnormality to the terminal 20'. The message is sent to the EPC of the network 30; the EPC of the network 30 sends the SIP message of network abnormality to the terminal 20' through the base station 50.
