It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application described herein may be capable of operation in sequences other than those illustrated or described herein, for example. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion.
As shown in fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a calling system provided in the present application, where the calling system includes a calling terminal 1, a communication system 2, and a called terminal 3. When the calling terminal 1 and the called terminal 3 communicate, the calling terminal 1 firstly sends the voice packets to the communication system 2 in sequence, and the communication system 2 sends the voice packets to the called terminal 3 in sequence, so that the communication between the calling terminal 1 and the called terminal 3 is realized. The calling terminal 1 and the called terminal 3 may be narrowband private network terminals, broadband and narrowband convergence terminals, or broadband terminals, and the communication system 2 may be a server or a base station, etc.
In order to effectively reduce the risk of missing voice packets at the called end 3 in the call system and improve the reliability of the call, the application provides a method for preventing voice loss in the call. Referring to fig. 2 and 3, fig. 2 is a flow chart of an embodiment of a method for preventing voice loss in a call provided in the present application, and fig. 3 is an interaction diagram of an embodiment of a calling end, a communication system and a called end provided in the present application, where the method is applied to the communication system, specifically, the method includes:
s11: and sequentially sending a plurality of first voice packets to the called terminal, and caching the plurality of first voice packets for a preset time length to obtain cached voice packets, wherein the first voice packets have characteristic values.
The communication system sequentially sends a plurality of first voice packets to the called terminal so that the called terminal sequentially receives the plurality of first voice packets and sequentially broadcasts the plurality of first voice packets. The communication system always buffers a plurality of first voice packets for a predetermined period of time to obtain buffered voice packets.
The predetermined duration may be 3s, 5s, 10s, 15s, etc., for example, the first voice packet of 10s is always buffered in the communication system, so as to obtain a buffered voice packet. The predetermined time period may be specifically set according to a network disconnection or network cutting time or the like that may occur at the called end.
In this embodiment, the communication system automatically discards the first voice packet buffered before the predetermined time period. For example, the predetermined time is 10s, the communication system always buffers the voice packet for 10s, and automatically discards the voice packet before 10s, so as to save the space of the communication system and save the cost of the communication system. In another embodiment, the communication system may not discard the first voice packets buffered before the predetermined time period, but buffer the first voice packets in the communication system during one communication process, and delete all the first voice packets buffered in the communication process after the one communication process is finished. By the method, the risk of missing the first voice packet at the called terminal can be effectively reduced, and the reliability of calling of a calling system is improved.
Further, the first voice packet has a feature value, where the feature value may be any one of an MD5 value, a hash value, a sha value, or a key value, for uniquely identifying the first voice packet. The feature value of the first voice packet can be obtained through adding the communication system, and can also be obtained through directly adding the communication system at the calling end, so that the communication system can directly receive the first voice packet with the feature value from the calling end.
Specifically, in one embodiment, the calling end sends a voice packet to the communication system, and the communication system receives the voice packet and sets the characteristic values of the voice packets in sequence to obtain a first voice packet. In another embodiment, the calling end may set the feature value for the voice packet to obtain the first voice packet, and then the calling end directly sends the first voice packet to the communication system, so that the communication system directly receives the first voice packet with the feature value from the calling end. The specific end at which the characteristic value is set may be selected according to actual conditions, and is not particularly limited herein.
Alternatively, the calling and called terminals may be single-mode terminals or multimode terminals. When the calling terminal and the called terminal are multimode terminals, the calling terminal and the called terminal are taken as the dual-mode terminals for illustration. The calling end and the called end simultaneously support broadband communication and narrowband communication, and the communication system can comprise a broadband system and a narrowband system which are connected with each other, and the calling end and the called end can communicate through the broadband system or can communicate through the narrowband system. The broadband system and the narrowband system can buffer the first voice packet for a predetermined time simultaneously, so that the called end can still receive the first voice packet buffered by the communication system after switching networks.
In a specific embodiment, the calling end a performs voice communication with the called end B through the broadband system, at this time, the broadband system caches the first voice packet with a predetermined duration, and the broadband system simultaneously sends the cached first voice packet to the narrowband system, so that the narrowband system also caches the first voice packet with the predetermined duration.
It will be appreciated that in other embodiments, the first voice packet may be buffered only in the wideband system or only in the narrowband system for a predetermined period of time. In this way, the first voice packet cannot be normally received after the called terminal switches the network, and the first voice packet can be normally received only after the called terminal switches to the original network again.
S12: and receiving voice broadcasting abnormal information of the called terminal, wherein the voice broadcasting abnormal information comprises a characteristic value of a current voice packet broadcasted by the called terminal, and the current voice packet is a first voice packet currently broadcasted by the called terminal.
When the voice broadcast of the called terminal is abnormal, recording the voice broadcast abnormal information of the called terminal, and after the network of the called terminal is recovered to be normal (after the network is reconnected or network cutting is successful), sending the voice broadcast abnormal information to the communication system, so that the communication system receives the voice broadcast abnormal information. The voice broadcasting abnormal information comprises a characteristic value of a current voice packet broadcasted by the called terminal, wherein the current voice packet is a first voice packet currently broadcasted by the called terminal. The voice broadcasting abnormal information comprises a characteristic value of a first voice packet which is broadcasted most recently when the voice broadcasting of the called terminal is abnormal.
Optionally, when the called terminal is disconnected, the called terminal cannot normally receive the first voice packet, so that the broadcasting is interrupted, and at the moment, the called terminal is considered to have abnormal voice broadcasting. In other embodiments, when the called terminal cuts the network, the first voice packet cannot be normally received, and the broadcasting is interrupted, and at this time, the called terminal is considered to have abnormal voice broadcasting. When the voice broadcast of the called terminal is abnormal, the first voice packet which is broadcast most recently by the called terminal is recorded, and after the network of the called terminal is recovered to be normal, the characteristic value of the first voice packet which is broadcast most recently by the called terminal is sent to a communication system, namely the called terminal sends the characteristic value of the current voice packet to the communication system, and the communication system receives the characteristic value of the current voice packet of the called terminal.
S13: and matching the characteristic value of the current voice packet with the characteristic value of the first voice packet in the cached voice packets.
The communication system receives the characteristic value of the current voice packet sent by the called terminal, namely the communication system receives the characteristic value of the first voice packet which is recently played by the called terminal, and then matches the characteristic value of the current voice packet with the characteristic values of a plurality of first voice packets in the cached voice packets of the communication system so as to find out the first voice packet which is not broadcasted by the called terminal.
Specifically, when the feature value of the current voice packet is the same as the feature value of the first voice packet in the cached voice packet, the feature value of the current voice packet is considered to be matched with the feature value of the first voice packet in the cached voice packet. And when the characteristic value of the current voice packet is different from the characteristic value of the first voice packet in the cached voice packet, the characteristic value of the current voice packet is not matched with the characteristic value of the first voice packet in the cached voice packet. Through the characteristic value matching, the position of the first voice packet which is recently broadcasted by the called terminal can be found out from the cached voice packets, and the first voice packet after the position in the cached voice packet can be considered, and the called terminal does not broadcast.
S14: and responding to the successful matching, and sending the first voice packet after the first voice packet matched with the characteristic value of the current voice packet in the cached voice packets to the called terminal.
After the characteristic value of the current voice packet is successfully matched with the characteristic value of a certain first voice packet in the cached voice packets, the called terminal can be considered to broadcast only to the certain first voice packet. The communication system sequentially sends the first voice packets after the certain first voice packet in the cached voice packets to the called terminal, so that the called terminal can continue broadcasting the first voice packets which are played when interrupted before. For example, 100 first voice packets are cached in the cached voice packets, the characteristic value of the current voice packet is matched with the 50 th first voice packet in the cached voice packets, so that the called terminal can be considered to broadcast only the fifty th first voice packet, and then the communication system sequentially sends the first voice packets after the 50 th first voice packet to the called terminal.
In summary, unlike the situation in the prior art, in the method of the foregoing embodiment, the communication system caches the first voice packet for a predetermined period of time to obtain the cached voice packet, so that when the voice broadcast of the called terminal is abnormal, the communication system can send the first voice packet received by the called terminal, which is not in the cached voice packet, to the called terminal, so as to reduce the risk of voice loss of the called terminal in the calling process, and improve the reliability of the calling system.
The present application also provides another embodiment of a method for preventing voice loss in a call, referring to fig. 4, fig. 4 is a schematic flow chart of another embodiment of the method for preventing voice loss in a call, where the method is applied to a terminal (called end), and the method specifically includes:
s21: and sequentially receiving a plurality of first voice packets sent by the communication system, wherein the communication system caches the plurality of first voice packets with preset duration to obtain cached voice packets, and the first voice packets have characteristic values.
The communication system sequentially sends a plurality of first voice packets to the terminal, and the terminal sequentially receives the plurality of first voice packets sent by the communication system and sequentially broadcasts the plurality of first voice packets. The communication system caches a plurality of first voice packets of a predetermined duration to obtain cached voice packets. The first voice packets have characteristic values, that is, each first voice packet received by the terminal includes a characteristic value, so that the first voice packet is uniquely marked by the characteristic value. The feature value may be any one of an MD5 value, a hash value, a sha value, or a key value.
S22: and sending voice broadcasting abnormal information of the terminal to the communication system, wherein the voice broadcasting abnormal information comprises characteristic values of current voice packets broadcasted by the terminal, and the current voice packets are first voice packets currently broadcasted by the terminal.
And when the voice broadcasting of the terminal is abnormal, sending the voice broadcasting abnormal information of the terminal to a communication system. For example, when a network abnormality occurs in the terminal, the first voice packet cannot be normally received from the communication system, and at this time, a voice broadcast abnormality may be caused. The abnormal voice broadcast of the terminal includes a case when the terminal is disconnected from the network, or a case when the terminal performs network switching (such as switching from a broadband network to a narrowband network), and the like, where the process of receiving the first voice packet by the terminal is interrupted.
Specifically, when the voice broadcast of the terminal is abnormal, the terminal records the characteristic value of the current voice packet broadcasted by the terminal. The current voice packet is a first voice packet currently broadcasted by the terminal, namely, a first voice packet which is broadcasted most recently when the voice broadcast of the terminal is abnormal. And after the terminal is normally connected again (for example, after the terminal is connected again to the internet or the network is switched successfully), the characteristic value of the current voice packet is sent to the communication system, so that the communication system can know the latest first voice packet broadcast when the voice broadcast of the terminal is abnormal, and the communication system can conveniently send the first voice packet which is not broadcast by the terminal to the terminal in the cached voice packets. By the mode, the terminal can not lose the voice packet even when the network is abnormal, and the communication reliability is improved.
S23: and receiving a first voice packet after the first voice packet matched with the characteristic value of the current voice packet in the cached voice packets of the communication system.
After the terminal sends the characteristic value of the current voice packet to the communication system, the communication system matches the characteristic value of the current voice packet with the characteristic value of the first voice packet in the cache voice packet, and after the matching is successful, the communication system sends the first voice packet behind the first voice packet matched with the characteristic value of the current voice packet in the cache voice packet to the terminal. The terminal can continue to play the following first voice packet following the first voice packet which is newly broadcasted when the voice broadcast is abnormal, the risk of the terminal losing the voice packet is reduced, and the reliability of communication is improved.
Specifically, after the communication system successfully matches the characteristic value of the current voice packet with the characteristic value of a certain first voice packet in the cached voice packets, the terminal can be considered to broadcast only to the certain first voice packet. The communication system sequentially sends the first voice packets after the certain first voice packet in the cached voice packets to the terminal, so that the terminal can continue broadcasting the first voice packets which are played when the terminal is interrupted before. For example, 100 first voice packets are cached in the cached voice packets, the characteristic value of the current voice packet is matched with the 50 th first voice packet in the cached voice packets, so that the terminal can be considered to broadcast only the 50 th first voice packet, and then the communication system sequentially sends the first voice packets after the 50 th first voice packet (namely, 51 th to 100 th voice packets in the cached voice packets) to the terminal. The terminal receives the first voice packet after the 50 th first voice packet in the cached voice packets, and then sequentially plays the received first voice packets.
Regarding the step of the communication system for caching the first voice packet, obtaining the cached voice packet and searching for the first voice packet matching the feature value of the current voice packet from the cached voice packet according to the feature value of the current voice packet, please refer to the embodiment shown in fig. 2 and the related text description above, which will not be repeated herein.
In the above embodiment, the terminal records the characteristic value of the current voice packet when broadcasting is abnormal, and after the terminal is connected to the network normally again, the terminal sends the characteristic value of the current voice packet to the communication system, so that the communication system searches the first voice packet which is not broadcasted by the terminal from the cached voice packets, and sends the first voice packet which is not broadcasted by the terminal to the terminal, thereby reducing the risk of missing the voice packet by the terminal and improving the reliability of the terminal call.
