If the status synchronization response fed back by the second user equipment is not received after the waiting timer expires, then this can be abandoned. The second state synchronization, or, re-send the state synchronization request to the second user equipment.

Preferably, the method also includes:

Specifically, this step may be performed while sending the state synchronization request to the second user equipment through SMS signaling, or before or after sending the state synchronization request to the second user equipment through SMS signaling, the first When the user equipment performs status check processing on itself, for example, the first user equipment chooses to dial an encrypted call on the TD-SCDMA network, then check whether the current network of the first user equipment is in the TD-SCDMA network, if so, the status check is successful, otherwise , try to switch the current network to TD-SCDMA network.

Preferably, the method also includes:

After the first user equipment determines that the state synchronization with the second user equipment is successful according to the state synchronization response, if it determines that there is no need to perform state synchronization with the second user equipment, resume its own The status before the status check is processed, so that the original business can continue.

Correspondingly, on the opposite end user equipment side, referring to FIG. 2 , a method for state synchronization between user equipment provided by an embodiment of the present invention includes steps:

S201. When the second user equipment receives the status synchronization request sent by the first user equipment, acquire the status synchronization information therefrom;

S202. The second user equipment judges whether it can perform state synchronization with the first user equipment according to the state synchronization information, and feeds back a state synchronization response to the first user equipment through SMS signaling.

The result determines whether the second user device has successfully completed synchronization for the type of content that needs to be synchronized.

The following describes the synchronization process by taking the synchronization method based on the short message signaling as an example to realize the encrypted call. Through the synchronization method of SMS signaling, the status requirements and event processing instructions of one party to the other party in an encrypted call are sent to the other party in real time, so that both parties can simultaneously switch the network to a network that can realize encrypted calls, such as TD-SCDMA network or TD-LTE network to realize encrypted calls.

Referring to FIG. 3 , the encrypted speech terminal 1 (ie, the first user equipment) and the encrypted speech terminal 2 (ie, the second user equipment) are provided with an encrypted speech module, a device synchronization module and a communication module.

The encrypted speech module of the encrypted speech terminal 1 (i.e. the first user equipment) intends to initiate an encrypted speech call to the encrypted speech terminal 2 (i.e. the second user equipment), and the device synchronization module in the encrypted speech terminal 1 obtains the encrypted speech terminal 1 (i.e. the second user equipment). A notification of the encrypted call module of the user equipment) that initiates an encrypted call, and the device synchronization module in the encrypted call terminal 1 starts a waiting timer. It is used to wait for an event response from the other party's encrypted conversation terminal 2, and perform corresponding processing. For example, if the other party's encrypted conversation terminal 2 has not responded for a long time (for example, because the other party shuts down), the synchronization process needs to close the synchronization process after the waiting timer expires.

The device synchronization module of the encrypted call terminal 1 sends a status synchronization request message to the device synchronization module of the encrypted call terminal 2, which contains the protocol version, serial number, synchronization type, synchronization parameters, etc. Among them, the protocol version is used for the compatible support of the user equipment to the old version of the protocol after the protocol is upgraded. The protocol is a protocol that can be recognized by both parties in the synchronization process, and is a private protocol specially designed for this synchronization process; the serial number is used as a single call unique identifier to prevent signaling overlap caused by SMS delay and timeout; the synchronization type is used to define the device synchronization type, such as network status synchronization (0x01), Bluetooth switch synchronization (0x02), etc.; synchronization parameters are used to indicate the specific synchronization type Requirements, such as the synchronization of the calling user equipment and the called user equipment to the TD-S network 0x01, the synchronization of the calling user equipment and the called user equipment to the TD-LTE network 0x02, etc.

The device synchronization module in the encrypted phone terminal 1 initiates a network detection and preparation request to the communication module in the encrypted phone terminal 1, that is, the encrypted phone terminal 1 performs status check processing on itself, if the encrypted phone terminal 1 chooses to dial the encrypted call, and the current network is in the TD-SCDMA network, the communication module returns successfully, otherwise, the return fails; if the encrypted call user equipment chooses to dial the encrypted call in the TD-LTE network, and the current network is in the TD-LTE network, the communication module returns successfully, Otherwise, return failure.

After the device synchronization module of the encrypted call terminal 2 receives the status synchronization request message sent by the encrypted call terminal 1, the device synchronization module of the encrypted call terminal 2 initiates a network detection and preparation request to the communication module of the encrypted call terminal 2, that is, the encrypted call terminal 2 Whether oneself can carry out state synchronization with encrypted call terminal 1 is judged and processed, if the synchronization type in the state synchronization request selects to dial encrypted call in TD-SCDMA network, and current network is in TD-SCDMA network, then the communication of encrypted call terminal 2 The module returns successfully to the device synchronization module of the encrypted call terminal 2, otherwise, the return fails; if the synchronization type in the status synchronization request is selected to dial the encrypted call on the TD-LTE network, and the current network is in the TD-LTE network, the encrypted call terminal 2 The communication module returns success to the device synchronization module of the encrypted phone terminal 2, otherwise, returns failure.

If the network condition is good, that is, the network setting of the encrypted call terminal 2 can satisfy the state synchronization request of the encrypted call terminal 1, and can be set correctly, then the device synchronization module of the encrypted call terminal 2 starts a holding timer for waiting for feedback from the other party. Prevent the other party from entering a long-term wait when there is no response.

The encrypted phone terminal 2 returns a status synchronization response to the encrypted phone terminal 1 through a short message, which carries the protocol version, serial number, synchronization type, synchronization result of the encrypted phone terminal 2, etc., and the function of carrying the protocol version is to indicate the communication Whether the protocol adopts a unified version is mainly to prevent misunderstandings caused by communication protocol upgrades. Simultaneously, the encrypted speech terminal 2 starts a waiting timer for waiting for the other party to initiate an encrypted call. If the encrypted speech call initiated by the other party has not been received when the timer expires, it exits the synchronization state and restores the previous state. The synchronization result refers to the result fed back by the called user equipment, such as success (identified by 0x00), no network request (identified by 0x01), or the called party is busy (identified by 0x02).

After the encrypted voice terminal 1 receives the synchronous response message sent by the encrypted voice terminal 2, when the synchronization result is successful, the encrypted voice module in the encrypted voice terminal 1 initiates a confidential call to the encrypted voice module in the encrypted voice terminal 2.

After the confidential conversation ends, the encrypted conversation module in the encrypted conversation terminal 1 notifies the equipment synchronization module in the encrypted conversation terminal 1 to restore the previous network settings, and similarly, the encrypted conversation module in the encrypted conversation terminal 2 notifies the equipment synchronization module in the encrypted conversation terminal 2 Restore previous network settings. In order to carry out encrypted communication, both the calling party and the called party need to switch the network to TD_SCDMA or LTE. In order to maintain the continuity of the user's original experience, after the end of the encrypted call, the calling party and the called party actively set the network to the network before the encrypted call.

It should be noted that, when the above-mentioned encrypted conversation module in the encrypted speech terminal 1 initiates a confidential call to the encrypted speech module in the encrypted speech terminal 2, the conversations are carried out through the voice channels of the communication modules in the encrypted speech terminal 1 and the encrypted speech terminal 2 respectively. , that is, the interaction between the encrypted speech module in the encrypted speech terminal 1 and the encrypted speech module in the encrypted speech terminal 2 must be forwarded through the communication modules of the respective terminals. Similarly, the interaction between the device synchronization module in encrypted call terminal 1 and the device synchronization module in encrypted call terminal 2 must also be forwarded through the communication modules of their respective terminals, but the forwarding is carried out by the SMS channel in the communication module .

In summary, the embodiment of the present invention has high synchronization efficiency based on short message signaling, and its real-time performance, security and arrival rate can all meet the requirements of second-level real-time information synchronization. Therefore, synchronization based on short messages can be realized on the current operator network, and based on the device status synchronization and event sending capabilities of this method, high real-time services can be realized.
