Background technique

The Voice over Long Term Evolution (VoLTE) service is a telecommunications service that uses commercial encryption technology to protect voice calls based on the 4th Generation (4G) mobile communication service. It can ensure that the voice call between the calling terminal and the called terminal is not eavesdropped by others. Call forwarding is the act of transferring a call request message to another terminal when the called terminal cannot answer the call, but the encrypted call request message should not be transferred to another terminal. Generally, after the calling terminal initiates an encrypted call request message to the called terminal, if it receives a call being forward (181 call being forward) response message sent by the service processing server corresponding to the called terminal, it will actively hang up the encrypted call. This prevents the encrypted call request message from being forwarded to another terminal. However, the above method implements the termination of encrypted calls on the terminal side, so that the encrypted call forwarding processing is separated from the management of the business system and is not subject to the control of the business system, and the processing flow is relatively cumbersome.

Detailed ways

The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure.

It will be understood that reference throughout this specification to "embodiments of the present disclosure" or "the foregoing embodiments" means that a particular feature, structure, or characteristic associated with the embodiment is included in at least one embodiment of the disclosure. Therefore, the appearances of "in embodiments of the present disclosure" or "in the preceding embodiments" in various places throughout this specification are not necessarily referring to the same embodiment. Furthermore, the particular features, structures or characteristics may be combined in any suitable manner in one or more embodiments. In various embodiments of the present disclosure, the size of the sequence numbers of the above-mentioned processes does not mean the order of execution. The execution order of each process should be determined by its functions and internal logic, and should not be determined by the implementation process of the embodiments of the present disclosure. constitute any limitation. The above serial numbers of the embodiments of the present disclosure are only for description and do not represent the advantages and disadvantages of the embodiments.

Unless otherwise specified, when the electronic device performs any step in the embodiments of the present disclosure, the processor of the electronic device may perform the step. It is also worth noting that the embodiments of the present disclosure do not limit the order in which the electronic device performs the following steps. In addition, the methods used to process data in different embodiments may be the same method or different methods. It should also be noted that any step in the embodiments of the present disclosure can be executed independently by an electronic device. That is, when an electronic device executes any step in the following embodiments, it does not depend on the execution of other steps.

It should be understood that the specific embodiments described here are only used to explain the present disclosure and are not intended to limit the present disclosure.

Embodiments of the present disclosure provide a communication processing method, which can be applied in communication devices. Referring to Figure 1, the method includes the following steps:

Step 101: Receive a first message sent by the first terminal to establish a call.

Step 102: When the communication device determines that the call forwarding conditions are met, the second message is sent to the first terminal or is not processed.

The first terminal may be the calling terminal, and the second terminal may be the called terminal. The first message may be a message sent by the first terminal to establish a call with the second terminal.

It should be noted that the methods provided by the embodiments of the present disclosure can be applied not only to 4G telecommunications networks, but also to fifth-generation networks (The 5th Generation, 5G)\sixth-generation networks (The 6th Generation, 5G). Generation, 6G)....etc. in telecommunications networks, and can also be applied to the Internet. Under different network architectures, communication devices that implement this method may have multiple implementation methods:

For example, in a 4G telecommunications network, an optional implementation of the communication device is an application server (Application Server, AS) that handles VoLTE calls, referred to as VoLTE AS for short. For another example, in a 5G telecommunications network, an optional implementation of the communication device is a wireless-based voice transmission application server (Voice over New Radio Application Server, VoNR AS). For another example, in the Internet, an optional implementation mode of the communication device may be an IP-based voice transmission application server (Voice over Internet Protocol Application Server, VoIP AS).

The above three situations are only a few examples provided by the embodiments of the present disclosure. During actual implementation, those skilled in the art may adopt other implementation methods according to the actual situation. For example, other communication devices may be used to implement this function. In addition, the communication device that implements the method to be protected by this disclosure may be one device or a combination of multiple devices. As long as the communication device uses the method provided by the embodiment of the present disclosure to perform corresponding operations, it should fall within the protection scope of the present disclosure.

The method provided by the present disclosure will be specifically described below by taking the communication device as VoLTE AS under the 4G telecommunications network architecture as an example.

In an implementable manner, the communication device may not be a device specifically designed to handle VoLTE encrypted calls. In this case, the calls processed by the communication device may be encrypted calls or unencrypted calls. Therefore, in this case, the first The message needs to include a message that directly or indirectly indicates that the call type is an encrypted call (explicit indication or implicit indication). Then, after receiving the first message, the communication device needs to determine whether the first message is a message to establish an encrypted call. , therefore in such a case, step 102 may specifically be: Step 102: If the call is an encrypted call and the communication device determines that the call forwarding conditions are met, send the second message to the first terminal or do not process it.

In another implementable manner, the communication device may be a device that specifically handles VoLTE encrypted calls. In this case, the calls processed by the communication device are all encrypted calls. Therefore, the first message sent by the first terminal does not need to include a direct or indirect representation of the call. The type is encrypted call information, because the communication device must process encrypted call messages. At this time, the first message only needs to include a request to establish a call between the first terminal and the second terminal, and the communication device does not need to determine whether the call is an encrypted call after receiving the first message, and can directly perform step 102. Of course, it is not excluded that if there are certain purposes in actual implementation, such as for the uniformity of the call establishment request format, the first It is also okay for the request to include information that directly or indirectly indicates that the call type is an encrypted call. It just means that the communication device does not need to read the encrypted call information and does not need to determine whether it is an encrypted call.

It should be noted that the control method for encrypted telephones involved in the embodiments of the present disclosure can be applied to encrypted telephone systems based on keys generated by pseudo-random numbers, physical noise sources, quantum, etc.

Two scenarios are provided in step 102 of this disclosed embodiment:

The first situation is: sending the second message to the first terminal. The second message is used to instruct the first terminal to stop the call. For example, the second message may be a 403 forbidden response message, used to instruct the first terminal to stop the call.

The second situation is: the communication device does not process it. Specifically, it means that the communication equipment does not perform any operation when it determines that the call forwarding conditions are met. In this case, the first terminal can be set with a timer, and the first terminal can start timing after sending the message, and automatically stop the call when the timer times out to protect the security of the voice call.

In the embodiment of the present disclosure, call forwarding refers to the behavior of the second terminal transferring the call connection to another terminal when the phone is unable to answer the call or is unwilling to answer the call, which is also called call transfer or incoming call transfer.

In the embodiment of the present disclosure, call forwarding conditions include but are not limited to: the communication device triggers unconditional call forwarding; or the communication device triggers call forwarding when busy; or the communication device triggers no-answer call forwarding; or the communication device Trigger unreachable call forwarding; or, the communication device determines and triggers enhanced call forwarding based on user configuration conditions.

It should be noted that the encrypted call is to protect the voice call transmitted between the first terminal and the second terminal, so the call can only be established between the first terminal and the second terminal. If the second terminal transfers the call to another terminal, it may pose a threat to the security of the call. Therefore, in the method embodiment provided by the present disclosure, if it is determined to be an encrypted call and the conditions for call forwarding are met, let the second terminal One terminal stops the call, thus effectively ensuring the security of encrypted calls. Moreover, the call forwarding processing is controlled by the business system, and the processing process is relatively simple. This solves the problem in related technologies that the encrypted call forwarding processing is separated from the management of the business system, is not controlled by the business system, and the processing process is relatively cumbersome.

The basic interaction flow chart between various devices is shown in Figure 2. The process in Figure 2 is consistent with the text description in Figure 1 and will not be repeated here.

Based on the foregoing embodiments, the specific flow chart of the communication processing method provided by the embodiment of the present disclosure can be referred to FIG. 3-FIG. 7 . It should be noted that Figures 3 to 7 only show the case where the VoLTE AS is an AS that handles ordinary calls and encrypted calls, and the VoLTE AS will reply to the first terminal with a second message. If the VoLTE AS is an AS that specifically handles encrypted calls, the first message does not need to carry the encryption identifier. If the first terminal is set with a timer, the AS will not send the second message, and the first terminal will stop the call after timeout.

As an implementable method, the process corresponding to the communication device triggering unconditional call forwarding is shown in Figure 3. Among them, the first terminal is user equipment (User Equipment, UE) (A), the second terminal is UE (B), the core network (Core Network, CN) (A) is the core network to which the first terminal is attached, and the core network CN(B) is the core network to which the second terminal is attached, AS(A) is the application server (VoLTE AS) corresponding to the first terminal, and AS(B) is the application server (VoLTE AS) corresponding to the second terminal. UE(A) may send an INVITE encrypted call request message (ie, the above-mentioned first message) to AS(B), and the INVITE encrypted call request message may be sent to AS(B) via CN(A) and AS(A). After receiving the INVITE encrypted call request message, AS(B) determines that the call type is an encrypted call based on the INVITE encrypted call request message, and when UE(B) activates the unconditional call forwarding service, AS(B) sends The 403 forbidden response message is sent to the first terminal. The 403 forbidden response message can be sent to the first terminal via AS(A) and CN(A), so that the first terminal terminates the encrypted call after receiving the 403 forbidden response message to ensure the voice call. safety. Alternatively, the communication device may not perform processing when unconditional call forwarding is triggered (not shown in the figure). In this case, the first terminal may be set with a timer, and the first terminal may start timing after sending the message. , automatically stops the call when the timer times out to protect the security of voice calls.

In an implementable manner, the process corresponding to the communication device triggering call forwarding when busy is shown in Figure 4. UE (A) sends an INVITE encrypted call request message to UE (B), and the INVITE encrypted call request message can Sent to UE(B) via CN(A), AS(A), AS(B), CN(B). At this time AS(B) may have learned that the current call is an encrypted call. If UE(B) is busy, a 486 busy response message may be sent to AS(B) via CN(B). After receiving the 486busy response message, AS(B) can send an ACK message to UE(B) via CN(B) for confirmation. When it determines that it needs to trigger busy call forwarding, it sends a 403 forbidden response message. To the first terminal, the 403 forbidden response message may be sent to the first terminal via AS(A) and CN(A), so that the first terminal terminates the encrypted call after receiving the 403 forbidden response message to ensure the security of the voice call. Alternatively, when the communication device triggers call forwarding when busy, it may not perform processing (not shown in the figure). In this case, the first terminal may be set with a timer, and the first terminal may start after sending the message. Timing, automatically stop the call when the timer times out to protect the security of voice calls.

In an implementable manner, the process corresponding to the communication device triggering no-response call forwarding is shown in Figure 5. UE(A) sends an INVITE encrypted call request message to UE(B), and the INVITE encrypted call request message can Sent to UE(B) via CN(A), AS(A), AS(B), CN(B). AS(B) determines that the call type is an encrypted call based on the INVITE encrypted call request message. When AS(B) waits for a timeout, it can send a CANCEL message to UE(B) via CN(B) to terminate the call ringing. After receiving the CANCEL message, UE(B) can send the CANCEL message to UE(B). CN(B) sends a 200OK message to AS(B) for confirmation. When AS(B) determines that it needs to trigger the activation of no-response call forwarding service, it sends a 403 forbidden response message to the first terminal. The 403 forbidden response message can be sent to the first terminal via AS(A) and CN(A). Terminal, so that the first terminal can terminate the encrypted call after receiving the 403 forbidden response message to ensure the security of the voice call. Alternatively, the communication device may not perform processing when triggering no-response call forwarding (not shown in the figure). In this case, the first terminal may be set with a timer, and the first terminal may start after sending the message. Timing, automatically stop the call when the timer times out to protect the security of voice calls.

In an implementable manner, the process corresponding to the communication device triggering unreachable call forwarding is shown in Figure 6. UE (A) sends an INVITE encrypted call request message to HSS (B), and the INVITE encrypted call request message can Sent to AS(B) via CN(A) and AS(A). AS(B) determines that the call type is an encrypted call based on the INVITE encrypted call request message. When AS(B) determines that the second terminal is not registered, it sends a User Data Request (UDR) request message to the Home Subscriber Server (HSS) to obtain the domain selection information of the second terminal. For example, it may be a Circuit Switched Domain Routing Number (CSRN). When the HSS fails to query the domain selection information of the second terminal, it sends a User Data Answer (UDA) failure response message to AS(B). After AS(B) receives the UDA failure response message, if AS(B) determines that unreachable call forwarding needs to be triggered, it sends a 403 forbidden response message to the first terminal. The 403 forbidden response message can be sent via AS(A) and CN(A) is sent to the first terminal, so that the first terminal can terminate the encrypted call after receiving the 403 forbidden response message to ensure the security of the voice call. Alternatively, the communication device may not perform processing when unreachable call forwarding is triggered (not shown in the figure). In this case, the first terminal may be set with a timer, and the first terminal may start after sending the message. Timing, automatically stop the call when the timer times out to protect the security of voice calls.

In an implementable manner, users can configure call forwarding conditions (ie, user configuration conditions) by themselves, for example, they can configure call forwarding time, etc. In this case, the triggered call forwarding is enhanced call forwarding. change. The communication device determines and triggers the enhanced call forwarding process based on user configuration conditions as shown in Figure 7. UE (A) sends an INVITE encrypted call request message to AS (B), and the INVITE encrypted call request message can be sent via CN ( A) and AS(A) send to AS(B). After receiving the INVITE encrypted call request message, AS(B) determines that the call type is an encrypted call based on the INVITE encrypted call request message, and determines that enhanced call forwarding needs to be triggered based on user configuration conditions, and sends a 403 forbidden response. message to the first terminal, the 403forbidden response message can be sent to the first terminal via AS(A) and CN(A), so that the first terminal can terminate the encrypted call after receiving the 403forbidden response message to ensure the security of the voice call. Alternatively, when the communication device determines and triggers enhanced call forwarding based on user configuration conditions, it may not perform processing (not shown in the figure). In this case, the first terminal may be set with a timer, and the first terminal You can start the timer after sending the message and automatically stop the call when the timer expires to protect the security of voice calls.

Based on the foregoing embodiments, embodiments of the present disclosure provide a communication processing method. Referring to Figure 8, after receiving the first message sent by the first terminal (step 101), the communication device determines that the call forwarding condition is not satisfied. In this case, step 103 can be performed.
