Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a call processing method and a call terminal.
Background
With the development of LTE (Long Term Evolution), it is possible to implement uniform Voice over LTE (LTE Voice) in which data and Voice services are in the same network, and the progress is also ongoing. Since VoLTE does not need a 2G/3G network, all services are borne on a 4G network, and the effects of shorter connection waiting time, higher quality and more natural voice/video call can be achieved.
The baseband chip is an important part for realizing communication in the mobile terminal, and is used for synthesizing a baseband chip signal to be transmitted or decoding a received baseband chip signal. Specifically, when transmitting, the audio signal is compiled into a baseband chip code for transmission; upon reception, the received baseband chip code is interpreted as an audio signal. Meanwhile, the system is also responsible for compiling address information (mobile phone numbers and network addresses), text information (short message texts and website texts) and picture information. The baseband chip may be divided into five sub-blocks: a CPU processor, a channel compiler, a digital signal processor, a modem (modem), and an interface module.
In order to improve the security of voice telephone of users and ensure that the contents of the calls between the calling and called users are not intercepted by attackers, traditional telecom operators and many communication and internet companies have introduced encrypted telephones. The encryption telephone adopts a cryptographic algorithm to protect the voice content, and can realize the concealment of the plaintext voice content. Even if the encrypted voice information of the two parties of the call is intercepted, the unauthorized person cannot know the real call content of the user.
However, for the call hold function of the mobile terminal, the mobile user who is in the process of communication can temporarily interrupt the original telephone and make a new telephone while keeping contact with the original telephone; when the original call needs to be replied, the newly-made call is kept, and then the call with the original call party is continued, namely, the two calls can be selected and switched by operating the keys of the mobile phone, and the call with the call party can be respectively or simultaneously ended.
In addition, VoLTE encrypted telephony requires restrictions on call hold services. The existing method is to switch off the user call hold service from the service management perspective, which, although it is possible to restrict VoLTE encrypted phone call hold, would have an impact on the standard VoLTE phone call hold service, so that the user cannot set call hold for the standard VoLTE phone.

Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
The invention provides a call processing method aiming at the problem that the existing VoLTE encrypted telephone can not meet different call requirements when the call holding service of a user is closed from the service management angle, as shown in figure 1, the call processing method comprises the following steps:
and 102, refusing to process the call when the call type is the ciphertext call.
According to the call processing method provided by the embodiment of the invention, according to the step 101 and the step 102, if a terminal initiates a new call during a call, the call type of the call is acquired; and then refusing to process the call when the call type is the ciphertext call. Therefore, when a user carries out ciphertext communication, the initiated new call is rejected in the call processing of the terminal and cannot be successfully established, the terminal which is carrying out encryption communication can be limited to initiate the new call under the condition of not closing the call holding service, the influence of the VoLTE encryption telephone on the standard VoLTE telephone call holding service is avoided, the service logic is simplified, different communication requirements are met, and meanwhile, the safety of sensitive communication contents is ensured.
It should be noted that, in the embodiment of the present invention, a state identifier is set for a call, and preferably, the state identifier "0" is a plaintext call identifier, and the state identifier "1" is a ciphertext call identifier. The terminal determines the specific value of the state identifier by monitoring whether the user triggers encryption when the user initiates a call. Therefore, on the basis of the above embodiment, in step 101, the step of obtaining the call type of the call includes:
detecting a state identifier of the call;
if the state identifier is detected to be a ciphertext call identifier, determining that the call type of the call is a ciphertext call;
and if the state identifier is detected to be a plaintext call identifier, determining that the call type of the call is a plaintext call.
Here, by detecting the state identifier of the call, the current call type of the call is determined according to the specific content of the state identifier, that is, the state identifier is detected to be a ciphertext call identifier (state identifier "1"), and the call type of the call is determined to be a ciphertext call; and detecting that the state identifier is a plaintext call identifier (state identifier '0'), and determining that the call type of the call is a plaintext call. Of course, the status flag can be realized by presetting letters, character strings, etc. besides using "0" and "1" to represent plaintext call and ciphertext call, which are not listed here.
In addition, in the embodiment of the present invention, the terminal is a VoLTE encryption terminal, and the framework of the VoLTE encryption terminal is as shown in fig. 2, and the VoLTE encryption terminal mainly includes software, an operating system and hardware, where the software includes a state & medium process module, a password management module, a call function module, a telephone interface service module and an antenna interface layer, and the hardware includes a mobile storage password card and a baseband chip, where the baseband chip is composed of a modem and a codec, a call initiated by a user is submitted to the baseband chip for processing through the software, and the call processing of the terminal is implemented by depending on the baseband chip. Therefore, to initiate a new call, the terminal passes a new call request triggered by the user to the baseband chip. Therefore, specifically, step 102 includes:
and rejecting to process a new call initiated in the ciphertext conversation through a baseband chip of the terminal.
Here, after the call request corresponding to the new call is transferred to the baseband chip via software, the baseband chip can refuse to process the call based on the determined current call being a ciphertext call. Therefore, the terminal refuses to process the call through the baseband chip, so that a new call is not established in the call state of the ciphertext call, the control on call establishment in the call state of the ciphertext call is completed, the influence of the VoLTE encryption phone on the standard VoLTE phone call holding service is effectively avoided, different call requirements are met, and the safety of sensitive call content is ensured.
In addition, on the basis of the above embodiment, the call processing method according to the embodiment of the present invention further includes:
when the call type is a plaintext call, acquiring the call type of the call;
and when the call type is the cipher text call, refusing to process the call.
Here, in order to prevent confusion between the secret speech and the plain speech in the process of simultaneously performing the ciphertext speech and the plain speech, the secret message is transmitted in the plain speech, and in the case that the acquired speech type is the plain speech and a new call is initiated, the call type of the call is acquired first, and then when the call type is the ciphertext call, the call is refused to be processed.
Specifically, when the call type is a ciphertext call, the step of rejecting processing the call includes:
and rejecting to process a new ciphertext call initiated during plaintext communication through a baseband chip of the terminal.
As known from the above, the architecture of the VoLTE encryption terminal is shown in fig. 2, and the call processing flow is implemented by relying on a baseband chip. Similarly, after the call request corresponding to the new call is transmitted to the baseband chip by the software, the baseband chip can refuse to process the call based on the fact that the determined current call is a plaintext call and the call is a ciphertext call. Therefore, the terminal refuses to process the call through the baseband chip, so that a new ciphertext call is not established any more in the conversation state of the plaintext conversation, the control on the call establishment in the conversation state of the plaintext conversation is completed, the influence of the VoLTE encryption telephone on the standard VoLTE telephone call keeping service is effectively avoided, and the conversation safety is improved.
In the case where the call is a plaintext call and the call is a plaintext call, since a conflict between the encrypted call and the call waiting service does not occur, the call processing method according to the embodiment of the present invention further includes:
and when the call type is a plaintext call, controlling the call to be successfully established.
Therefore, when the call is a plaintext call and the initiated new call is a plaintext call, the call security is not affected, the new call is controlled to be successfully established, and the call requirement of the user is met. The specific implementation of controlling the successful establishment of the call is that the call is successfully established through the processing of the baseband chip.
As can be seen from the above, the solution provided by the embodiment of the present invention well solves the problem that different call requirements cannot be met when the user call hold service is closed from the service management perspective for the VoLTE encrypted phone in the prior art, and can implement the following contents:
1. forbidding a user who is carrying out ciphertext conversation to initiate a new call, including a plaintext call or a ciphertext call;
2. the user who is on the clear text call is prohibited from initiating a new cipher text call.
Specifically, according to different implementation manners, an exemplary implementation based on a terminal is provided in the embodiments of the present invention, and the main contents are as follows:
it is assumed that a call between VoLTE encrypted terminals (terminals having a function of making an encrypted call) a and B is established and the terminal A, B opens a call waiting service, at which time the user of the calling terminal a inputs the telephone number of another terminal C on the user call interface and triggers the call key to initiate a call to the called terminal C.
As shown in fig. 3, the software of the calling terminal a will transmit the received call request triggered by the user to the baseband chip, and after receiving the call request, the baseband chip determines the communication type of the local terminal, and if ciphertext communication is being performed, the baseband chip will refuse to process the newly initiated call.
Or, as shown in fig. 4, the software of the calling terminal a may transmit a received call request triggered by the user to the baseband chip, and after receiving the call request, the baseband chip determines the call type of the local terminal, and if the call type is a ciphertext call, the baseband chip rejects to process a newly initiated call; if the calling type is a plaintext calling, the baseband chip responds to the calling request and successfully establishes a calling with the called terminal C.
In summary, in the call processing method of the embodiment of the present invention, the VoLTE encryption terminal refuses to process a new call through the baseband chip of the terminal in the process of performing a ciphertext call; in the process of carrying out plaintext communication, a baseband chip of the terminal refuses to process a new ciphertext call and normally processes a new plaintext call, so that the VoLTE encrypted telephone does not influence the standard VoLTE telephone call holding service, the service logic is simplified, different communication requirements are met, and the safety of sensitive communication contents is ensured.

According to the communication terminal provided by the embodiment of the invention, if the terminal initiates a new call during communication, the communication type of the communication is acquired; and then refusing to process the call when the call type is the ciphertext call. Therefore, when a user carries out ciphertext communication, a new call initiated by the user is rejected in the call processing of the terminal and cannot be successfully established, the terminal which is carrying out encryption communication can be limited to initiate the new call under the condition of not closing the call holding service, the influence of the VoLTE encryption telephone on the standard VoLTE telephone call holding service is avoided, the service logic is simplified, different communication requirements are met, and the safety of sensitive communication contents is ensured to be optional, wherein the first acquisition module comprises:
