Mobile Switching Office, Mobile service Switching Office, MSO.
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The invention is suitable for the speech intercommunication between two different languages, such as between Chinese and English, between English and Japanese, between Japanese and American, between American and Russian, between Russian and Chinese, etc.; for convenience of illustration and understanding, the following examples take two different languages of "chinese" and "english" as examples, and the speech processing method is described in detail. It will be appreciated that speech talkback between other two different languages is equally applicable.
Referring to fig. 1a, the present invention provides a speech processing system comprising:
a mobile switching office 100.
A plurality of base stations 200 connected to a mobile switching office.
Each base station has a plurality of registered terminals 300 within its coverage area, which in this application are narrowband terminals that can be used to perform walkie-talkie operations. To simplify processing, subsequent mobile switching offices are denoted MSOs.
Referring to fig. 1b, the method further includes, on the basis of fig. 1 a: a translation server 400 connected to the MSO; and a configuration device 500.
For ease of understanding, fig. 1a and 1b take three base stations as an example: base1, Base2, and Base3, terminals with chinese users and english applications under Base1, terminals with only english users under Base2, and terminals with only chinese users under Base 3.
Before performing the on-line speech processing, some preparatory operations need to be performed:
firstly, a terminal is initialized by using a configuration terminal so as to add a voice type identifier into the terminal.
Before each terminal is used, the configuration device 600 is operated by a network administrator, and the voice type identification of the respective terminal is initialized by the configuration device 600. Initializing a Chinese type identifier for the terminal and storing the identifier in the terminal under the condition that a user of the terminal is a Chinese user; and initializing an English type identifier for the terminal and storing the identifier in the terminal under the condition that the terminal user is an English user.
Secondly, each base station stores the voice type identification of the registered terminal in the coverage area and sends the voice type identification to the MSO, so that the MSO can store the voice type identification of the registered terminal in the coverage area of each base station;
after the terminal is initialized, the terminal becomes a registered terminal, and the registered terminal can work in a group calling mode. The base station can interact with the registered terminals in the coverage area and send the voice type identification to the base station, so that the voice type identification of the registered terminals is stored in the base station.
Thirdly, the MSO stores the group identifier of each group, and the group member terminal identifier included in each group identifier. Each base station also sends the voice type identification of the registered terminal in the coverage area to the MSO, so that the MSO can store the voice type identification of the registered terminal in the coverage areas of different base stations respectively.
There may be different groups (groups) in the speech processing system, different registered terminals in different groups, and the MSO stores the group identification of different groups and the speech type identification of the group member terminals of different groups.
The invention provides a voice processing method, which is applied to a voice processing system shown in FIG. 1a or FIG. 1 b. Referring to fig. 2, the method comprises the following steps:
step S201: the mobile exchange office receives the group call request initiated by the calling terminal and establishes a group call.
For ease of description, the mobile switching office is hereinafter denoted as MSO. Referring to fig. 3, this step can be implemented in the following manner:
step S301: a calling terminal initiates a group calling request to an MSO through a calling base station; wherein the group call request includes a group identification.
A push area of "PTT allowed" may be displayed on the display screen of the calling terminal, indicating that the calling terminal has the right of talk when the push area of "PTT allowed" is colored, and indicating that the calling terminal does not have the right of talk when the push area of "PTT allowed" is gray.
In the case where the calling terminal has the right to speak, the user can select one group among different groups and can press the "PTT allowed" pressing area for a long time. At this time, the calling terminal initiates a group call request, and the group call request includes a group identifier.
And the calling base station sends the group calling request to the MSO.
Step S302: the MSO receives a group call request initiated by a calling terminal, determines each group member terminal identification corresponding to the group identification, each participating base station corresponding to each group member terminal identification, and determines a voice type identification corresponding to each group member terminal identification.
The MSO receives a group call request initiated by a calling terminal, determines the identification of each group member terminal in the group based on the group identification in the group call request, and acquires a base station corresponding to the identification of each group member terminal, which is called a participating base station.
For example, each group member terminal identifies three corresponding base stations as Bsae1, Bsae2, and Bsae3 in fig. 1.
Step S303: and judging whether the voice type identifications of all the group member terminals are completely consistent, and if not, entering the step S304.
Step S304: and under the condition that the voice type identifications of all the group member terminals are not completely consistent, determining first state information which represents different voice type identifications and needs to execute translation operation.
After determining the identifier of each group member terminal, the MSO may determine the voice type identifier corresponding to each group member terminal. If some group member terminal identifiers correspond to a first voice type identifier (such as a Chinese type identifier), and some group member terminal identifiers correspond to a second voice type identifier (such as an English type identifier), it indicates that the voice type identifiers of the group member terminals are not completely consistent.
And under the condition that the voice type identifications of all the group member terminals are not completely consistent, determining first state information which represents different voice type identifications and needs to execute translation operation. And the MSO sends the first state information to each participating base station.
And sending the first state information to each participating base station.
Step S305: and the MSO sends the first state information to each participating base station.
The MSO also sends first status information to each participating base station for each participating base station to determine the operating slot mode.
Step S306: each participating base station determines a working mode according to the first state information and the voice type identification of the registered terminal; the registered terminal voice type identification of the participating base station is determined as a double-time slot working mode if the voice type identification is not completely consistent, and the registered terminal voice type identification of the participating base station is determined as a single-time slot working mode if the voice type identification is completely consistent.
The participating base station has registered terminals in the coverage area, acquires the voice type identifiers of the registered terminals in the storage space, and if the voice type identifiers of the registered terminals are not completely consistent (for example, Bsae1 in FIG. 1), the participating base station determines that the participating base station works in a double-slot working mode, so that one slot is used for receiving the uplink voice data packet subsequently, and the other slot is used for receiving the translated voice data packet, thereby receiving the two types of voice data packets in parallel, improving the receiving efficiency and reducing the time delay.
The participating base station obtains the voice type identifier of the registered terminal in the storage space, and if the voice type identifiers of the registered terminals are completely consistent (for example, Bsae2 and Bsae3 in fig. 1), the participating base station determines to operate in the single-slot operating mode, so as to subsequently receive the uplink voice data packet or translate the voice data packet by using a single slot.
The calling terminal may transmit voice data during a long press on the "PTT allowed" press zone after the group call is established. As the speaking time becomes longer, the voice data will also become larger gradually, and in order to improve the real-time performance and the sending efficiency, the calling terminal generates an uplink voice data packet at intervals of a preset time (for example, 60ms), and the uplink voice data packet includes a voice type identifier of the calling terminal, which is called as a first voice type identifier for convenience of differentiation.
Step S201 then proceeds to step S202: and the calling terminal sends an uplink voice data packet containing the first voice type identifier.
The calling terminal constructs an uplink voice data packet containing the voice fragment and the first voice type identifier, and sends the uplink voice data packet to the calling base station, and the calling base station sends the uplink voice data packet to the MSO.
The flow proceeds to step S203: and the MSO receives an uplink voice data packet which is sent by the calling terminal and contains a first voice type identifier, and sends the uplink voice data packet to each participating base station with the first voice type identifier so that each participating base station can send the uplink voice data packet to a registered terminal according to a working time slot mode.
The MSO already knows the group id of the group call request during the process of establishing the group call, and the voice type id status of each participating Base station in the group id, for example, terminals with different voice type ids under Base1, terminals with the same voice type id under Base2 and being english type ids, and terminals with the same voice type id under Base3 and being chinese type ids.
Therefore, after receiving the uplink voice data packet containing the first voice type identifier, the MSO determines each participating base station containing the first voice type identifier from the participating base stations (i.e. the terminal completely under the participating base station is the first voice type identifier, and the terminal under the participating base station has both the first voice type identifier and the second voice type identifier).
And the MSO sends the uplink voice data packet to each participating base station containing the first voice type identifier so that each participating base station can send the uplink voice data packet to the registered terminal according to the working time slot mode.
If the participating base station is completely the terminal with the first voice type identifier, the participating base station works in a single time slot working mode, and the participating base station directly sends an uplink voice data packet to the registered terminal through a single time slot.
If the participating base station has the terminal with the first voice type identifier and the terminal with the second voice type identifier, the participating base station works in a double-time-slot working mode, and the participating base station sends an uplink voice data packet to the registered terminal through the first time slot.
Step S204: and the MSO acquires a translation voice data packet corresponding to the uplink voice data packet, and sends the translation voice data packet containing the second voice type identifier to each participating base station with the second voice type identifier, so that each participating base station can send the translation voice data packet to a registered terminal according to a working time slot mode.
The steps S204 and S203 are parallel steps, and the execution process is not in sequence.
The MSO determines in step S201 that the first state information, i.e. the MSO, needs to perform a translation operation.
In the speech processing system shown in fig. 1a, the MSO may have a built-in translation module, and perform a translation operation on the upstream speech data packet by using the translation module, so as to obtain a translated speech data packet. The MSO adds a second voice type identification to the translated voice data packet.
In the speech processing system shown in fig. 1b, the MSO may send an uplink speech data packet to the translation server, and obtain a translation speech data packet sent by the translation server. The MSO adds a second voice type identification to the translated voice data packet.
The MSO determines each participating base station that contains the second voice class identification (i.e., the terminal under the participating base station that is completely the second voice class identification, and the terminal under the participating base station that has both the first voice class identification and the second voice class identification).
If the participating base station is the terminal completely identified by the second voice type, the participating base station works in a single time slot working mode, and the participating base station directly sends the translation voice data packet to the registered terminal through a single time slot.
If the participating base station has the terminal with the first voice type identifier and the terminal with the second voice type identifier, the participating base station works in a double-time-slot working mode, and the participating base station sends the translation voice data packet to the registered terminal through the second time slot.
By adopting a double-time-slot mode to respectively send the uplink voice data packet and the translation voice data packet, the voice data packet can be sent in parallel by two languages, so that the problem that the translation voice data packet can be sent only after the uplink voice data packet is sent under the condition of single time slot is solved, and the time delay is shortened.
Step S205: and the registered terminals under each participating base station receive the voice data packet, compare the voice type identifier in the voice data packet with the local voice type identifier, receive and play the voice data packet if the voice type identifier is consistent with the local voice type identifier, and discard the voice data packet if the voice type identifier is inconsistent with the local voice type identifier.
The registered terminal under each participating base station receives the voice data packet (uplink voice data packet and/or translated voice data packet), and then compares the voice type identifier in the voice data packet with the local voice type identifier.
If the voice data packet is consistent with the local voice type identifier, namely the voice which can be understood by the user is directly received and played. If the voice data packet is inconsistent with the local voice type identifier, the voice data packet is indicated to be inconsistent with the local voice type identifier, namely the voice data packet is discarded if the voice data packet cannot be understood by the user.
Taking Bsae1, Bsae2, and Bsae3 in fig. 1 as examples, a registered terminal in Base1 receives both an uplink voice data packet and a translated voice data packet, but the registered terminal only receives and plays a voice data packet consistent with its own voice type identifier, so as to ensure that a user can receive an understandable voice; voice data packets inconsistent with the voice type identifier are discarded to ensure that the user does not receive unintelligible voice.
The Base2 only receives the translation voice data packet and directly receives and plays the translation voice data packet; bsae3 receives only the upstream voice packets and directly receives and plays the upstream voice packets.
Step S206: after receiving the end frame fed back by each base station, the MSO sends a speaking right releasing instruction to each participating base station, so that each participating base station sends the speaking right releasing instruction to the registered terminal.
Continuously sending an uplink voice data packet containing a first voice type identifier until the speaking right is released during the calling terminal executing group calling; and the calling base station generates an end frame after receiving the talk right release information and sends the end frame to the MSO.
The MSO repeatedly executes step S203 until all uplink voice data packets are completely transmitted, and then transmits an end frame to each participating base station having the first voice type identifier, so that each participating base station transmits the end frame to the registered terminal, and the participating base station feeds back the received end frame to the MSO after receiving the end frame.
The MSO repeatedly executes the step S204 until all the translation voice data packets are completely issued, and then issues an end frame to each participating base station with the second voice type identification so that each participating base station can issue the end frame to the registered terminal; and after receiving the end frame, the participating base station feeds back the received end frame to the MSO.
After receiving the end frame received by all the participating base stations, the MSO indicates that all the uplink voice data packets have been sent, and all the translated voice data packets have been sent, that is, the one-time group call of the calling terminal has been executed.
The MSO forbids the group calling authority of other terminals in the calling time limit of the calling terminal, optionally during the period, in order to improve the experience, the prompt information in the speaking can be displayed. Preferably, the Chinese "speaking" is displayed for the Chinese terminal, and the English "talking" is displayed for the English terminal.
Therefore, after the group call of the calling terminal is finished, the calling terminal sends a speaking right releasing instruction to each participating base station, so that each participating base station sends the speaking right releasing instruction to the registered terminal.
Step S207: and after the registered terminal receives the command of releasing the speaking right, displaying that the group calling operation area is in an available state.
A push area of "PTT allowed" may be displayed on the display screen of the registered terminal, and the color of the push area of "PTT allowed" indicates that the group call operation area is in an available state.
Optionally, since it takes some time for the translation voice data packet to be translated, when all the uplink voice data packets are completely issued, all the translation voice data packets are not completely issued, and therefore, after the uplink voice data packets are completely issued, before the translation voice data packets are completely issued, a time difference exists.
For the terminals which finish the transmission of all the uplink voice data packets, a period of idle time exists in the period, but the speaking right of the terminals cannot be recovered in the idle time. In order to improve user experience, prompt information in speech translation is displayed when a registered terminal receives an end frame and does not receive a talk right release instruction. Preferably, the Chinese language "in speech translation" is displayed for the Chinese terminal, and the "talking" is continuously displayed for the English terminal.
Through the technical means, the following beneficial effects can be realized:
after the group call is established, the MSO can respectively execute two parallel operations: a parallel operation is used for directly sending the uplink voice data packet containing the first voice type identifier to the participating base station which does not need the translation operation, and the participating base station sends the uplink voice data packet to the registered terminal. And the registered terminal under the participating base station receives and plays the uplink voice data packet only under the condition that the local voice type identifier is consistent with the first voice type identifier. This operation enables upstream voice data packet distribution to registered terminals.
And the other parallel operation is used for translating the uplink voice data packet to obtain a translated voice data packet, then sending the translated voice data packet to a participating base station needing translation operation, and the participating base station issuing the translated voice data packet to the registered terminal. And the registered terminal under the participating base station receives and plays the translated voice data packet only under the condition that the local voice type identifier is consistent with the second voice type identifier. This operation enables the delivery of the translated voice data packet to the registered terminal.
The scheme can be suitable for real-time voice communication in a group calling scene.
Referring to fig. 4, the present invention further provides a speech processing method, which may include the following steps:
step S401: the MSO receives the group call request initiated by the calling terminal and establishes the group call.
Referring to fig. 5, this step can be implemented by the following steps:
step S501: a calling terminal initiates a group calling request to an MSO through a calling base station; wherein the group call request includes a group identification.
Step S502: the MSO receives a group call request initiated by a calling terminal, determines each group member terminal identification corresponding to the group identification, each participating base station corresponding to each group member terminal identification, and determines a voice type identification corresponding to each group member terminal identification.
Step S503: and judging whether the voice type identifications of all the group member terminals are completely consistent, and if not, entering the step S504.
Step S504: and under the condition that the voice type identifications of all the group member terminals are completely consistent, determining second state information which represents the same voice type identification and does not need to execute translation operation.
Step S505: and the MSO sends the second state information to each participating base station.
Step S506: and each participating base station determines a single-time-slot working mode according to the second state information.
Because the group member terminals are all in the same language, the participating base stations do not need to adopt a double-time-slot working mode, and only need to adopt a single-time-slot working mode.
Step S402: and the calling terminal sends an uplink voice data packet containing the first voice type identifier.
Step S403: and the MSO receives an uplink voice data packet which is sent by the calling terminal and contains a first voice type identifier, and sends the uplink voice data packet to each participating base station with the first voice type identifier so that each participating base station can send the uplink voice data packet to a registered terminal according to a working time slot mode.
Step S404: and the registered terminals under each participating base station receive the uplink voice data packet, compare the voice type identifier in the uplink voice data packet with the local voice type identifier, receive and play the uplink voice data packet if the voice type identifier is consistent with the local voice type identifier, and discard the uplink voice data packet if the voice type identifier is inconsistent with the local voice type identifier.
Step S405: after receiving the end frame fed back by each base station, the MSO sends a speaking right releasing instruction to each participating base station, so that each participating base station sends the speaking right releasing instruction to the registered terminal.
Continuously sending an uplink voice data packet containing a first voice type identifier until the speaking right is released during the calling terminal executing group calling; and the calling base station generates an end frame after receiving the talk right release information and sends the end frame to the MSO.
The MSO repeatedly executes step S403 until all uplink voice data packets are completely transmitted, and then transmits an end frame to each participating base station with the first voice type identifier, so that each participating base station transmits the end frame to the registered terminal, and the participating base station feeds back the received end frame to the MSO after receiving the end frame.
After receiving the feedback of all participating base stations and receiving the end frame, the MSO indicates that all uplink voice data packets have been sent, that is, that one-time group calling of the calling terminal has been executed.
The MSO forbids the group calling authority of other terminals in the calling time limit of the calling terminal, optionally during the period, in order to improve the experience, the prompt information in the speaking can be displayed. Preferably, the Chinese "speaking" is displayed for the Chinese terminal, and the English "talking" is displayed for the English terminal.
Therefore, after the group call of the calling terminal is finished, the calling terminal sends a speaking right releasing instruction to each participating base station, so that each participating base station sends the speaking right releasing instruction to the registered terminal.
Step S406: and after the registered terminal receives the command of releasing the speaking right, displaying that the group calling operation area is in an available state.
