When data is transmitted in a conventional mobile network, a terminal transmits and receives service data and information through the mobile network, and at this time, the terminal is first connected to a service gateway to register in the service network. After the registration is completed, when the service is to be performed between the terminals, the call request signaling of the calling terminal is firstly sent to the service gateway of the home terminal, and the home terminal service gateway completes the addressing of the called terminal. After contacting the called terminal, the call request signaling is sent to the called terminal through the service gateway of the called terminal, and the called terminal processes the call request and answers. The call response signaling is sent to the calling terminal, and in the process of call establishment, the calling terminal and the called terminal mutually send IP address information for establishing media bearer, and may also include information such as upper layer protocol type and port number according to the difference of the media type and the protocol. Then the calling terminal and the called terminal establish a media connection to perform the actual media service, and the media connection is not passed through the service gateway and the service network, but is directly routed between the respective bearing gateways through the IP backbone network. According to the data communication process in the mobile network, the terminal needs to tell the opposite terminal about the IP address allocated from the network, and because the IP address allocation on the public data network has a corresponding relation with the region, the current position of the terminal can be known from the IP address, and the privacy of the user is exposed.

In some embodiments, before establishing the communication connection, performing location update of the terminal through a call forwarding APP, specifically including:

s111: replacing the real number of the mobile terminal with a designated number through a call forwarding APP;

s112: sending the designated number to a CTD platform for carrying out a position updating request;

s113: and the CTD platform initiates authentication and registration to the visitor location register, and registers the specified number in the visitor location register of the CTD platform to correspond to the mobile terminal.

As shown in fig. 2, the location updating process includes:

STEP 1: a (Send _ authentication _ info) MSC (Mobile switching Center)/VLR (Visitor Location Register) requires authentication of a user, and if an authentication parameter of the user is not available in a local database, the VLR may apply for a new authentication parameter of the user from an HLR (Home Location Register).

STEP 2: (Send _ authentication _ info ack) HLR returns the authentication parameter set of the user after successful execution.

STEP 3: (Update _ Location) the CTD-MAP initiates a Location Update request to the HLR, and updates the Location information of the user with the number F to the CTD platform.

STEP 4: (Cancel _ Location) if the user F has been switched on in a certain MSC/VLR, the MSC/VLR receives a Location deletion request from the HLR, deletes the record from the user data according to the user identifier IMSI in the parameter, wherein the IMSI is an International Mobile Subscriber Identity (IMSI), and releases the TMSI of the user, and the TMSI is a Temporary Mobile Subscriber Identity (TMSI).

STEP 5: (Cancel _ Location _ ack) regardless of whether the subscriber is registered in the VLR, the MSC/VLR returns confirmation of Location deletion to the HLR and closes the session.

STEP 6: (Insert _ Subscriber _ Data) the CTD-MAP sends a location update request to the HLR, causing the HLR to initiate a Subscriber Data insertion operation to transfer the Subscriber Data stored in the HLR for use by the CTD-MAP. The CTD-MAP can acquire the mobile phone number of the user, namely the MSISDN number, according to the received message.

STEP 7: (Insert _ Subscriber _ Data _ ack) CTD-MAP confirms that all Subscriber Data from the HLR is correct, and returns a confirmation primitive to the HLR.

STEP 8: (Update _ Location _ ack) the end of the HLR Location Update process returns a confirm primitive to the CTD-MAP.

In the embodiment, the terminal position is updated through the call transfer APP before the communication connection is established, the communication connection is established through the call transfer APP at the updated position, and the communication is not carried out through the SIM card, so that the data transmission can be carried out without a base station, and the normal use of the call function of the operator network is ensured while the position information of the user is hidden.

STEP 3: the called end office receives the encrypted call identifier and connects the call to the called terminal;

STEP 4: after receiving the INVITE, the called terminal finds whether to carry the encrypted call identifier, and can select whether to carry out the encrypted call communication, and if the encrypted call communication is carried out, sends 183 the encrypted call identifier;

STEP 5: the called terminal sends 200OK answering call;

STEP 6: and the secret call negotiation is successful, and the secret call conversation is carried out.

STEP 1: the calling terminal sends an INVITE message carrying a secret call identifier; at this time, the calling number is a fixed network number.

STEP 2: after receiving the INVITE message, the calling end office SBC forwards the INVITE message to the calling end office AS.

STEP 3: after receiving the INVITE message, the calling end office AS converts the calling number into a managed number. The call is returned to the SBC.

STEP 4: the calling end office SBC. The call is routed to the called end office.

STEP 5: the called end office continues the called party (VoLTE terminal).

STEP 6: and after receiving the INVITE message, the called terminal searches for the encrypted call identifier. When the INVITE carries the secret session identifier, if the secret session is to be carried out, a 183 message (carrying the secret session identifier) is sent.

STEP 7: and the called terminal answers.

STEP 8: and carrying out secret call.

In some embodiments, further comprising:

the real number is hosted in a home location register of an operator through a call forwarding APP, the call is forwarded to a fixed network IMS (IP Multimedia Subsystem) through the call forwarding APP, and data is transmitted between the fixed network IMS and a called terminal, for example, a VoLTE terminal.
