Detailed Description

The scheme of the embodiment of the application is suitable for realizing the speech right distribution control between any two communication systems in a converged communication system consisting of two or more communication systems, so that the terminal of one communication system can initiate a call to the terminal of the other communication system, and the terminal of one communication system can send a voice message packet to the terminal of the other communication system.

For ease of understanding, a system to which the solution of the embodiments of the present application is applied will be described.

For example, referring to fig. 1, a schematic diagram of a component architecture of a converged communication system composed of a plurality of communication systems according to the present application is shown. In fig. 1, it is shown that a converged communication system is a centralized networking of a plurality of communication systems by accessing gateways of the same communication system.

As can be seen from fig. 1, the converged communication system includes: communication system 1, communication system 2 and communication system 3.

The communication system 1 includes: a gateway 101 and at least one terminal connected to the gateway 101 through a network.

Accordingly, the communication system 2 includes: a gateway 102 and at least one terminal connected to the gateway 102 through a network. The communication system 3 includes: a gateway 103 and at least one terminal connected to the gateway 103.

The communication system 2 and the communication system 3 are connected to the communication system 1 as subsystems to form a converged communication system.

Specifically, the gateway 102 of the communication system 2 accesses the gateway of the communication system 1, and the gateway 103 of the communication system 3 accesses the gateway of the communication system 1. Accordingly, in the converged communication system, the gateway 102 of the communication system 2 serves as a converged gateway between the communication system 2 and the communication system 1; the gateway 103 of the communication system 3 serves as a convergence gateway between the communication system 3 and the communication system 1. And the gateway 101 of the communication system 1 serves as a convergence gateway of the entire convergence communication system.

The convergence gateway is a gateway for connecting two communication systems.

The specific implementation manner of the converged communication system formed by the communication system 2 and the communication system 3 through the access communication system 1 may be various, and the specific access manner is not limited in the present application.

It will be appreciated that different communication groups, each of which may include a plurality of terminals, may be maintained within the gateway of each of the converged communication systems. For example, a terminal may make a call to terminals within one or more communication groups via a group call. Wherein, a plurality of terminals in the same communication group can belong to different communication systems.

Meanwhile, the terminal in each communication system can call the terminal in another communication system in a personal calling mode.

It is understood that in the converged communication system shown in fig. 1, the communication system 2 and the communication system 3 are accessed to the communication system 1 as an example, but it is understood that when only one communication system is accessed to the communication system 1, for example, the communication system 2 is accessed to the communication system, and the same is also applicable to the embodiment; or, when more than two communication systems access the communication system 1, the structure and function of the formed converged communication system are similar, and are not described herein again.

For another example, refer to fig. 2, which shows a schematic diagram of another composition architecture of a converged communication system composed of multiple communication systems in the embodiment of the present application. Fig. 2 shows a cascaded network of a plurality of communication systems.

Fig. 2 shows that the converged communication system is formed by a plurality of communication systems in a cascade networking manner. Wherein, amalgamation communication system includes: communication system 1, communication system 2, communication system 3, and communication system 4.

The communication system 1 comprises a gateway 101 and at least one terminal connected to the gateway 101.

The communication system 2 includes a gateway 102 and at least one terminal connected to the gateway 102.

The communication system 3 comprises a gateway 103 and at least one terminal connected to the gateway 103.

Wherein, the communication system 1 is accessed to the gateway 102 of the communication system 2 through the gateway 101 in the communication system 1, so that the communication system 1 is accessed to the communication system 2 to form a first-level fusion system; and the gateway 102 of the communication system 2 accesses the gateway 103 of the communication system 3, so that the communication system 2 accesses the communication system 3 to form a two-level converged system. Fig. 2 shows three communication systems cascaded, and in practical applications, there may be more communication systems to form a multi-level fusion system.

In fig. 2, since each communication system is connected to at most two communication systems, the amount of information that the gateway of the communication system needs to maintain can be reduced. In the converged communication system of fig. 2, there may be various specific ways of implementing one communication system to access another communication system, and the present application is not limited thereto.

It is to be understood that, in the converged communication system shown in fig. 1 and 2, the plurality of communication systems constituting the converged communication system may be the same kind or may be different kinds.

Optionally, the types of the plurality of communication systems in the converged communication system are not all identical. For example, the two communication systems that access each other are not of the same type. For example, the communication system 1 accesses the communication system 2, the communication system 1 and the communication system 2 may be two different types of communication systems, for example, the communication system 1 may be a Push to Talk Over Cellular (POC) system, and the communication system 2 may be a conventional Digital Mobile Radio (DMR) system.

It should be noted that fig. 1 and fig. 2 are only two examples of a converged communication system composed of a plurality of communication systems, in practical applications, the plurality of communication systems may also form the converged communication system in other manners, and both right-of-speech control and message transmission between any two communication systems in the converged communication system formed in other manners are applicable to the scheme of the embodiment of the present application, and the present application does not limit how the converged communication system is specifically formed.

In the embodiment of the application, in order to enable the terminal between any two communication systems in the converged communication system to communicate and avoid the change of the terminal side, the speaking right control and the transmission of the voice message packet are performed through the gateway between the two communication systems.

In the embodiment of the application, a gateway in a first communication system to which a terminal initiating a call request belongs is taken as a speaking right control party to bear a main system role of a converged communication system. The terminal of the second communication system outside the first communication system is used as a called party, the gateway of the second communication system bears the slave system role of the converged communication system, and the gateway of the second communication system also bears the master system role inside the second communication system.

In the embodiment of the present application, a terminal of a first communication system requests to call a terminal of a second communication system as an example, where the first communication system and the second communication system may be the same type of communication system or different types of communication systems. For the sake of distinction, the gateway of the first communication system is subsequently referred to as the first gateway, and the gateway of the second communication system is subsequently referred to as the second gateway. Meanwhile, a terminal initiating a call request in the first communication system is referred to as a first terminal, and a terminal called in the second communication system is referred to as a second terminal.

With the above generality, the speaking right control method according to the embodiment of the present application is described below.

For example, referring to fig. 3, which shows a flowchart of an embodiment of a talk right control method according to the present application, in the embodiment of the present application, the method is described from a first gateway side of a first communication system, and the method of the present embodiment may include:

s301, receiving a call request initiated by a first terminal of a first communication system.

Wherein the call request is for requesting a call to at least one second terminal in the second communication system.

It can be understood that the call request may request to call one or more terminals in the first communication system in addition to at least one second terminal in the second communication system, and since the process of the first terminal calling the other terminals belonging to the first communication system and the first terminal is similar to the process of calling between terminals in the same communication system, the process is not limited in this application, and is not described herein again.

It can be understood that the call request may carry identification information of the called terminal, and the identification information of the called terminal may be an address of the terminal or a group to which the terminal belongs. The called terminal of the call requested by the call request can be identified by the identification information of the called terminal. In this embodiment, the identification information of the called terminal at least includes identification information of at least one second terminal in the second communication system.

For example, the call request may be a group call request or a call request (also referred to as a single call).

Wherein, in case that the call request is a call request, the call request is for requesting a call to a second terminal of the second communication system. For example, the call request may carry an address of the called second terminal or the like for uniquely identifying the second terminal.

In the case that the call request is a group call request, the call request may carry a group identifier of the requested call. The group identifier is an identifier of a communication group, and the communication group requested to be called by the call request can be characterized through the group identifier. In this embodiment, the communication group requested to be called by the group call request includes at least one second terminal of the second communication system.

It is understood that, in the case that the call request is a group call request, the communication groups of the group call request may include: the present embodiment is described in terms of a call process in which a first terminal calls at least one second terminal in one second communication system, although call processes for the second terminals in each second communication system are similar.

S302, in response to the call request of the first terminal, requesting a second gateway of the second communication system to establish a session connection for the call request.

For example, the first gateway forwards the call request sent by the first terminal to the second gateway of the second communication system to request to establish a session connection for the call request.

For another example, the first gateway sends, based on the call request of the first terminal, a call invitation request to a second gateway of the second communication system, where the call invitation request carries identification information of at least one second terminal requested to be called by the call request, and the call invitation request may request to establish a session connection with the second gateway of the second communication system.

After receiving the request of the first gateway for requesting to establish the session connection, the second gateway may determine whether it is currently suitable for receiving the voice message packet sent by the terminal of the first communication system, for example, determine whether the talk right in the second communication system is occupied, and if it is determined that it is currently suitable for receiving the voice message packet sent by the terminal of the first communication system, the second gateway may feed back an indication message for confirming establishment of the session connection to the first gateway. Correspondingly, after receiving the indication message, the first gateway confirms to establish the session connection between the first gateway and the second gateway.

For example, the second gateway may return a switch-on indication, e.g., 200OK, to the first gateway in the event that it is determined that it is currently suitable to receive voice message packets sent by the terminal of the first communication system. And after receiving the connection indication, the first gateway may return an acknowledgement message to the second gateway to complete the session connection between the first gateway and the second gateway.

S303, under the condition that the session connection between the first gateway and the second gateway is confirmed, allocating a talk right authorization for the call request to the first terminal.

The speaking right is also called a speaking right, and the terminal has the authority of sending voice to other terminals only when having the authority of the speaking right. Accordingly, after the first gateway allocates the right to speak for the call request to the first terminal, the first terminal has the right to call at least one second terminal requested by the call request, so that the first terminal can send the voice message packet to the at least one second terminal of the second communication system through the first gateway.

It will be appreciated that the specific implementation of the first gateway for assigning the floor grant to the first terminal may vary due to the type of the first communication system.

For example, in the case that the first communication system belongs to a communication system with a talk right mechanism, for example, the first communication system is a public POC system or a private DMR conventional system with a talk right, the first terminal needs to send a talk right application request for the call request to the first gateway, and for convenience of distinction, the talk right application request sent by the first terminal of the first communication system is referred to as a first talk right application request. The first gateway responds to a first speaking right application request sent by the first terminal, and returns speaking right authorization aiming at the first speaking right application request to the first terminal, so that the speaking right authorization is distributed to the first terminal.

For another example, in a case where the first communication system belongs to a communication system without a talk right mechanism, for example, the first communication system is a conventional system of a private network DMR without a talk right, the first terminal does not need to send a talk right application request to the first gateway. In this case, after the first gateway establishes a session connection with the second gateway, the first gateway may directly determine that the first terminal has the talk burst authority for the call request. That is, the first gateway confirms that the first terminal has the authority to send the voice message packet to the second communication system, and in this case, the first gateway may forward the voice message packet to the second gateway after receiving the voice message packet sent by the first terminal to the at least one second terminal.

It is understood that after the first gateway assigns the right to speak to the first terminal, the first gateway may forward the voice message packet sent by the first terminal to the second gateway, so as to forward the voice message packet to at least one second terminal of the call requested by the call request through the second gateway.

Further, in order to reduce resource occupation, the first gateway may also release the talk right of the first terminal in the case that the first terminal ends the call.

For example, the first gateway may determine that the first terminal ends sending the voice message packet when the time from the time when the first terminal last sent the voice message packet to the current time exceeds the preset time, that is, the first terminal ends sending the voice message packet, that is, the first gateway ends the call. For another example, when receiving the voice end packet sent by the first terminal, the first gateway confirms that the first terminal ends the call.

It can be seen that, in this embodiment of the present application, after receiving a call request initiated by a first terminal of a first communication system to at least one second terminal of a second communication system, a first gateway of the first communication system establishes a session connection between the first gateway and the second gateway of the second communication system for the call request, and after confirming that the session connection is established, allocates a talk right authorization for the call request to the first terminal, so that the first gateway can receive a voice message packet of the first terminal and forward the voice message packet to the second gateway, thereby implementing talk right allocation and control by a gateway to which the terminal initiating the call request belongs, and ensuring that terminals of two communication systems can call each other.

In addition, in the embodiment of the application, the speaking right distribution and control are realized by the gateway to which the terminal initiating the call request belongs, so that the development of the terminal side can be reduced, and the convenience of speaking right control among a plurality of communication systems is simplified.

It will be appreciated that after a first terminal of a first communication system has called a second terminal of a second communication system, the second terminal of the second communication system may also initiate a callback, in which case the second terminal may apply the right to speak to the first gateway of the second communication system via the second gateway.

For example, referring to fig. 4, which shows a flowchart of an embodiment of a talk right control method according to the present application, in the embodiment of the present application, the method is described from a first gateway side of a first communication system, and the method of the present embodiment may include:

s401, receiving a call request initiated by a first terminal of a first communication system.

S402, in response to the call request, requesting to establish a session connection for the call request from a second gateway of the second communication system.

S403, under the condition that the session connection between the first gateway and the second gateway is confirmed, allocating a talk right authorization for the call request to the first terminal.

The above steps S401 to S403 can refer to the related description of the previous embodiment, and are not described herein again.

S404, the voice message packet sent by the first terminal is forwarded to the second gateway, so that the voice message packet is forwarded to at least one second terminal through the second gateway.

It will be appreciated that after the first terminal obtains the floor authorization, the first terminal may send the voice message packet to the first gateway and forward the voice message packet to the second gateway through the first gateway. This step S404 does not belong to the process of speaking right assignment, and is an optional step for the purpose of facilitating understanding of the scheme of the present embodiment.

Similarly, in the case where the first gateway confirms that the first terminal ends the call, the first gateway may also release the floor of the first terminal.

S405, receiving a second right application request sent by a second gateway under the condition of maintaining the session connection established between the first gateway and the second gateway.

In order to distinguish from the speaking right application sent by the first terminal, the speaking right application request sent by the second gateway to the first gateway is called a second speaking right application request.

The second speaking right application request is generated by the second gateway in response to the speaking right application request or the voice starting instruction sent by the target second terminal. The target second terminal belongs to at least one second terminal requested to be called by the call request sent by the first terminal, that is, the target second terminal is a second terminal initiating a speaking right application request or a voice start instruction in the at least one second terminal.

It can be understood that, in the case of maintaining the session connection established between the first gateway and the second gateway for the call request, the second right application request sent by the second gateway to the first gateway is necessarily a right authorization request for the second terminal under the control of the second gateway to apply for initiating a call to the first terminal.

Accordingly, the speaking right application request or the voice starting instruction sent by the target second terminal is used for requesting the call request of the first terminal to carry out call back. The speaking right application request or the voice starting indication carries identification information of at least one terminal requesting calling, and the at least one terminal at least comprises the first terminal.

If the call request initiated by the first terminal is a call request, the speaking right application request or the voice starting instruction sent by the second terminal is used for representing that the first terminal needs to be called back. In this case, the speaking right application request or the voice start indication carries the identification information of the first terminal.

For another example, when the call request initiated by the first terminal is a group call request, the request for requesting for the right of speaking or the voice start instruction sent by the second terminal are both used to characterize that a call back is performed to the terminals in the group requested by the group call request. In this case, the speaking right application request or the voice start indication may carry a group identifier for requesting a call, where the group identifier is the same as the group identifier carried in the call request initiated by the first terminal.

It is to be understood that, due to the different types of the second communication systems, the specific process of triggering the second gateway in the second communication system to send the second right application request to the first gateway may also be different. For example, in the case that the second communication system is a communication system with a talk right mechanism, for example, the second communication system may be a public network POC system or a private network DMR conventional system with a talk right, and the second gateway may send the second talk right application request to the first gateway when receiving the talk right application request sent by the target second terminal. For example, the second gateway forwards the request for requesting the right of speaking sent by the target second terminal to the first gateway as a request for requesting the right of speaking.

For another example, in a case that the second communication system belongs to a communication system without a talk right mechanism, for example, the second communication system is a conventional system of a private network DMR without a talk right, the second terminal of the second communication system may directly send the voice start instruction to the second gateway without applying for the talk right to the second gateway. In this case, the second gateway transmits the second right application request to the first gateway when receiving the voice start instruction transmitted from the target second terminal.

S406, in response to the second floor application request, sending a floor authorization for the second floor application request to the second gateway under the condition that the second gateway is confirmed to have the floor authorization, so that the second gateway confirms that the target second terminal obtains the floor authorization of the first gateway.

The condition for determining whether the second gateway has the talk right authorization may be multiple possibilities, for example, the first gateway may detect whether there is a terminal in the first communication system to occupy the talk right, or the first gateway detects whether the first gateway is currently connected to a voice message packet sent by the second terminal, and so on. The present application does not limit the specific implementation manner of how the first gateway determines that the second gateway has the condition of the talk right authorization.

It will be appreciated that the condition under which the first gateway confirms that the second gateway has the right to speak authority is in fact the condition under which the target second terminal has the right to speak authority. In this case, the first gateway may send the talk burst authority for the second talk burst application request to the second gateway, so as to implement the talk burst authority for the target second terminal.

Correspondingly, after receiving the talk right authorization for the second talk right application request, the second gateway can confirm that the second terminal has the authority to send the voice message packet to the first gateway and the first terminal.

For example, in the case that the second communication system belongs to a communication system with a speaking right mechanism, the second gateway receives a speaking right application request sent by a target second terminal before sending the second speaking right application request to the first gateway, and in this case, the second gateway sends a speaking right authorization for the speaking right application request initiated by the second terminal to the second terminal.

For another example, in a case that the second communication system belongs to a communication system without a talk right, before the second gateway sends the second talk right application request to the first gateway, the second gateway receives a voice start instruction sent by the target second terminal, and after the second gateway receives the talk right authorization for the second talk right application request, the second gateway sends the voice start instruction to the first gateway and forwards the voice message packet sent by the target second terminal to the first gateway.

It is to be understood that, whether or not the second communication system has the talk burst, the second gateway forwards the voice message packet sent by the target second terminal to the first gateway after confirming that the target second terminal has the talk burst authority of the first gateway. Correspondingly, after receiving the voice message packet sent by the second gateway, the first gateway forwards the voice message packet to the first terminal, so that the second terminal of the second communication system can call back the first terminal of the first communication system.

It can be seen that, in this embodiment of the present application, in a case where a first terminal of a first communication system initiates a call request to at least one second terminal of a second communication system, a first gateway of the first communication system acts as a talk right controller of the first communication system and the second communication system, and is implemented to allocate a talk right authorization for calling the second terminal of the second communication system to the first terminal. Meanwhile, under the condition that a second terminal of the second communication system calls back the first terminal, a speaking right authorization can be sent to the first gateway through a second gateway of the second communication system, and the speaking right authorization is distributed to the second terminal initiating the call back by the first gateway, so that the second terminal can call the first terminal of the first communication system. Therefore, in the embodiment of the application, the gateway to which the terminal initiating the call request belongs serves as a talk right controller of the two communication systems, so that talk right allocation in the calling and callback processes is realized, the terminals of the two communication systems can call each other, and talk right allocation between any two communication systems is realized.

It is to be understood that, in any of the above embodiments of the present application, when the type of the call request sent by the first terminal is different, the process of establishing the session connection between the first gateway and the second gateway may also be different, so that the timing of allocating the right-to-speak authorization to the first terminal may also be different. Next, a process of the second gateway feeding back an indication message for confirming session connection to the first gateway is introduced for a case that the call request initiated by the first terminal is a group call and an individual call.

When a call request initiated by a first terminal is a call request, a first gateway further needs to establish session connection between the first gateway and the first terminal under the condition that the first gateway confirms that the session connection is established between the first gateway and a second gateway; the first gateway then assigns a floor grant for the call request to the first terminal. In this case, the specific manner in which the first gateway allocates the talk right authorization to the first terminal may also be any one of the aforementioned implementation manners, and details are not described herein again.

Correspondingly, when the call request is a call, when the second gateway receives the request of the first gateway for establishing the session connection for the call request, the second gateway needs to establish the session connection between the second network element and the second terminal requested to be called by the call request, and after the session connection is established between the second gateway and the second terminal, the second gateway agrees to establish the session connection with the first gateway.

In the case that the call request initiated by the first terminal is a group call request, since the first gateway can establish the session connection between the first gateway and the first terminal before requesting the establishment of the session connection to the second gateway, the first gateway can directly perform the operation of assigning the talk right authorization to the first terminal under the condition that the establishment of the session connection between the first gateway and the second gateway is confirmed.

Correspondingly, because the call request is a group call, when the second gateway receives the request of the first gateway to establish the session connection for the call request, the second gateway can directly establish the session connection with the first gateway without waiting for the second gateway to establish the session connection with at least one second terminal called by the call request.

Of course, in the case that the call request is a group call, the first gateway may also establish a session connection with the first terminal after establishing a session connection with the second gateway, and this case is also applicable to this embodiment, and is specifically similar to the case of an individual call, and will not be described herein again.

In order to facilitate understanding of the solution of the present application, the following description is made with reference to specific application scenarios. It is understood that, considering that the importance of the talk burst control between two different types of communication systems is higher, the two communication systems involved are different types of communication systems as an example.

For example, taking the talk right control between the public network POC system and the private network DMR conventional system as an example, the following is divided into cases.

First, a public network POC system and a private network DMR conventional system both belong to a communication system with a talk right control mechanism, and a POC terminal in the public network POC system initiates a call request to a DMR terminal in the private network DMR conventional system.

In this case, the public POC system corresponds to the first communication system. The POC gateway of the public network POC system is equivalent to the first gateway of the first communication system and takes the main control roles of the public network POC system and the private network DMR conventional system.

The private network DMR conventional system is equivalent to the second communication system, the transit gateway of the private network DMR conventional system serves as the second gateway of the public network POC system, the transit gateway of the private network DMR conventional system serves as the slave control role of the public network POC system and the private network DMR conventional system, and the transit gateway assumes the master control role in the private network DMR conventional system.

For example, referring to fig. 5, which shows a schematic flow interaction diagram of the talk right control method according to the embodiment of the present application in a case where a POC terminal in a public network POC system initiates a call request, the method of the embodiment may include:

s501, the POC terminal initiates a group calling request to the POC gateway.

The group call request is at least used for requesting to call a plurality of DMR terminals in a conventional system of a private network DMR. For example, the group call request may carry a group identifier of a group in which the terminal requesting the call is located.

Here, a group call request is taken as an example for requesting to call a plurality of DMR terminals of a private network DMR conventional system, but the same is also applicable to this embodiment if the group call request is used for requesting to call one DMR terminal of the private network DMR conventional system, for example, the group call request is used for requesting to call one DMR terminal of the private network DMR conventional system while requesting to call at least one terminal of another communication system.

For convenience of description, the present embodiment takes the call request as a group call request as an example, but it is understood that the present embodiment is also applicable to a single call request.

S502, the POC gateway responds to the group calling request and establishes session connection with the POC terminal.

For example, after receiving the group call request, the POC gateway may feed back a connection indication, e.g., 200OK, to the POC terminal in case that it is determined that the session connection with the POC terminal can be established; the POC terminal then sends an acknowledgement message to the POC gateway to complete the session connection between the POC terminal and the POC gateway.

S503, the POC gateway sends a call invitation to a transit gateway of a private network DMR conventional system in response to the group call request, so as to request to establish a session connection between the POC gateway and the transit gateway.

The call invitation carries a group identification of the group requested to be called by the group call request.

When the POC terminal initiates a call request, the POC gateway may send a call invitation carrying an identifier of the DMR terminal corresponding to the call request to the relay station gateway.

And S504, the transferring platform gateway responds to the call invitation, and establishes the session connection between the POC gateway and the transferring platform gateway.

As shown in fig. 5, the transit gateway acknowledges that the call invitation can be received and returns a connect indication, e.g., a 200OK, to the POC gateway. Accordingly, the POC gateway returns an acknowledgement message to the transit gateway in response to the on indication, and the session connection between the POC gateway and the transit gateway is established.

S505, the transit platform gateway sends a call invitation to the plurality of DMR terminals requesting the call of the group call request, so as to request session connection to be established with the plurality of DMR terminals.

If so, the transit platform gateway determines a plurality of DMR terminals belonging to the group represented by the group identifier according to the group identifier carried by the call invitation sent by the POC gateway, and establishes session connection with the plurality of DMR terminals by sending a call invitation request.

S506, the DMR terminal responds to the call invitation sent by the relay gateway, and session connection between the DMR terminal and the relay gateway is established.

For example, for any DMR terminal, the DMR terminal returns a connect indication, e.g., 200OK, to the transit gateway in response to the call invitation. Accordingly, after receiving the connection indication, the relay gateway may return an acknowledgement message to the DMR terminal to complete the session connection between the DMR terminal and the relay gateway.

It is understood that the above steps S501 to S506 belong to the interactive part of the control plane signaling.

The above steps S501 to S506 are described by taking the POC terminal as an example to initiate the group call request, but it is understood that if the POC terminal initiates a single call request, the embodiment is also applicable to the same, except that after the POC gateway sends the call invitation for the single call request to the transit gateway, the transit gateway needs to send the call invitation to the DMR terminal requested to be called by the single call request first, and after the DMR terminal establishes a session connection with the transit gateway, the transit gateway returns a connect indication to the POC gateway to complete the session connection between the transit gateway and the POC gateway.

S507, when the POC gateway confirms that the POC gateway establishes session connection for the call request with the relay gateway, the POC gateway receives the first right application request sent by the POC terminal.

Since the public POC system belongs to a communication system with a talk right, the POC terminal needs to send a talk right application request to the POC gateway before the POC terminal sends a voice message.

Similar to the previous embodiment, the speaking right application request sent by the POC terminal initiating the call request is referred to as a first speaking right application request.

S508, the POC gateway responds to the first talk right authorization request, and feeds back a talk right authorization for the first talk right authorization request to the POC terminal.

S509, the POC gateway forwards the voice message packet sent by the POC terminal to the transit gateway, so that the transit gateway forwards the voice message packet to a plurality of DMR terminals establishing session connection with the transit gateway.

After the POC terminal receives the floor authorization, the POC terminal may send a voice message packet to the POC gateway. Meanwhile, in order to enable the transit platform gateway to know that the POC terminal is about to send a message of a voice message packet, the POC gateway may send a voice start instruction to the transit platform gateway, where the voice start instruction is used to instruct a voice start transmission, for example, the voice start instruction may be a start message in a Real-time Transport Protocol (RTP).

For example, the step S509 may specifically include: the POC gateway sends a voice start indication to the transit platform gateway. And the POC gateway receives the voice message packet sent by the POC terminal and forwards the voice message packet to the relay station gateway. Then, the transit gateway forwards the voice message packet sent by the POC gateway to a plurality of DMR terminals establishing session connection with the transit gateway.

Further, the POC gateway receives a voice end instruction sent by the POC terminal, and forwards the voice end instruction to the relay station gateway; correspondingly, the transit platform gateway forwards the voice ending indication to a plurality of DMR terminals.

Wherein the end of utterance indication is used to indicate that transmission of the voice message packet is ended. If the POC terminal detects that the voice message packet is not received within the specified duration, it may send an end-of-speech indication to the POC gateway.

Of course, the POC gateway may also generate the voice end instruction and send the voice end instruction to the transit gateway when the voice message packet of the POC terminal is not received within the specified duration.

It will be appreciated that the POC gateway may also release the floor assigned to the POC terminal at the same time that the POC gateway receives or generates the end-of-speech indication.

S510, when the transit gateway establishes the session connection with the POC gateway, the transit gateway receives a second right application request sent by the DMR terminal.

It can be understood that, since the conventional system of the private network DMR to which the transit gateway belongs to the communication system with the talk right, for a plurality of DMR terminals to which the POC terminal requests a call, any one DMR terminal may send a request for applying the talk right to the transit gateway in case of wishing to call back to the POC terminal. For the convenience of distinguishing, the speaking right application request sent by the DMR terminal is used to generate a second speaking right application request.

It can be understood that, because of the group call request initiated by the POC terminal, the second right application request may request to obtain the right authority for the group corresponding to the group call request to call, and thus, the second right application request at least requests to obtain the right to call the POC terminal.

And S511, the relay gateway forwards the second talk right application request to the POC gateway.

S512, the POC gateway returns a talk right authorization indication for the second talk right application request to the transit platform gateway when confirming that the DMR terminal initiating the second talk right application request has a talk right authorization condition.

S513, the transit platform gateway forwards the right authorization indication for the second right application request to the corresponding DMR terminal.

After receiving the talk right authorization indication, the DMR terminal initiating the second talk right application request has the right to send the voice message packet to the POC terminal under the control of the POC gateway.

Similar to the previous step S509, in order to enable other DMR terminals except the DMR terminal initiating the second session right application request among the multiple DMR terminals called by the group call request to know that a voice message packet is to be sent, the relay platform gateway further sends a voice start instruction to the other DMR terminals among the multiple DMR terminals.

And S514, the transit platform gateway forwards the voice message packet sent by the DMR terminal with the talk right authorization to the POC gateway, so as to forward the voice message packet to the POC terminal through the POC gateway.

After receiving the voice message packet of the DMR terminal, the transit platform gateway not only forwards the voice message packet to the POC gateway, but also forwards the voice message packet to a DMR terminal that is not the DMR terminal and establishes a session connection with the transit platform gateway.

Accordingly, in the case that the transit gateway receives the end-of-speech indication of the DMR terminal or determines that generation of the end-of-speech indication is satisfied, the transit gateway further sends the end-of-speech indication to the POC gateway and other DMR terminals having session connection with the transit gateway.

In the embodiment of fig. 5, when the POC terminal initiates the call request, the POC gateway takes the role of primary control, and completes the implementation process of right allocation and control between the public network POC system and the private network DMR conventional system.

Under the condition that the DMR terminal initiates a call request, a transit platform gateway in the conventional private network DMR system can assume the main control roles of the public network POC system and the conventional private network DMR system, and the speech right distribution and control between the public network POC system and the conventional private network DMR system are completed. And the POC gateway is used as a slave control role for completing a converged communication system consisting of a public network POC system and a private network DMR conventional system. In this case, the private network DMR conventional system corresponds to the first communication system, and the transit gateway in the private network DMR conventional system corresponds to the first gateway in the first communication system, and the public network POC system corresponds to the second communication system, and the POC gateway corresponds to the second gateway in the second communication system.

When the DMR terminal initiates a call request, the operation that the transit gateway needs to perform is similar to the operation performed by the POC gateway in the embodiment of fig. 5, and the operation that the POC gateway needs to perform is similar to the operation performed by the transit gateway in the embodiment of fig. 5, and therefore, the description thereof is not repeated.

In the following, a public POC system is taken as a communication system with a talk right, and the private DMR conventional system is taken as an example, and a scenario that a POC terminal in the public POC system initiates a call request to a DMR terminal in the private DMR conventional system is taken as an example.

For example, referring to fig. 6, which shows another flow interaction diagram of a speaking right control method according to the present application, the method of this embodiment may include:

s601, the POC terminal initiates a group calling request to the POC gateway.

And S602, the POC gateway responds to the group calling request and establishes session connection with the POC terminal.

S603, the POC gateway sends a call invitation to a transit gateway of a private network DMR conventional system in response to the group call request, so as to request to establish a session connection between the POC gateway and the transit gateway.

S604, the transit gateway responds to the call invitation to establish a session connection between the POC gateway and the transit gateway.

S605, the transit platform gateway sends a call invitation to the plurality of DMR terminals requesting the call of the group call request, so as to request to establish session connection with the plurality of DMR terminals.

And S606, the DMR terminal responds to the call invitation sent by the relay gateway, and establishes session connection between the DMR terminal and the relay gateway.

It can be understood that the above steps S601 to S606 belong to an interaction part of control plane signaling, and a specific implementation process thereof is similar to the specific implementation process of steps S501 to S506 in the embodiment of fig. 5, which may specifically refer to the related description of the foregoing embodiment, and is not described again here.

The above steps S601 to S606 are described by taking the POC terminal as an example to initiate a group call request, but it is understood that the same is also applicable to the embodiment if the POC terminal initiates an individual call request.

S607, when the POC gateway confirms that the POC gateway establishes session connection for the call request with the relay gateway, the POC gateway receives the first right application request sent by the POC terminal.

S608, the POC gateway responds to the first talk burst authority request, and feeds back a talk burst authority for the first talk burst authority request to the POC terminal.

And S609, the POC gateway forwards the voice message packet sent by the POC terminal to the relay gateway so that the relay gateway forwards the voice message packet to a plurality of DMR terminals establishing session connection with the relay gateway.

The processes of steps S607 and S609 are similar to the processes of S507 to S509 in the embodiment of fig. 5, and reference may be made to the related descriptions above specifically, and details are not repeated here.

S610, when the transit gateway establishes the session connection with the POC gateway, the transit gateway receives the voice start instruction sent by the DMR terminal.

It can be understood that, because the conventional private network DMR system to which the transit gateway belongs to a communication system without a talk right mechanism, for multiple DMR terminals that the POC terminal requests for a call, it is not necessary for any DMR terminal to initiate a callback to send a talk right application request to the transit gateway, and therefore, the DMR terminal can directly send a voice start indication indicating that a voice message packet needs to be sent to the transit gateway.

It can be understood that, because of the group call request initiated by the POC terminal, in this embodiment, the receiving party corresponding to the voice start instruction should also be a group corresponding to the group call request, and therefore, the voice start instruction may carry a group identifier of the group corresponding to the group call request.

As can be seen, the voice start indication is at least used to indicate that a voice message packet needs to be sent to the POC terminal.

S611, the transit platform gateway sends a second request for requesting right to speak to the POC gateway in response to the voice start indication.

The transit platform gateway can determine that the DMR terminal under the control of the transit platform gateway needs to send a voice message packet to the POC terminal of the public network POC system according to the voice start instruction, and in this case, the transit platform gateway needs to request a talk right authorization from the POC gateway, that is, send a second talk right application request to the POC gateway.

The second talk right application request is used for requesting to apply for talk right authorization for the DMR terminal initiating the voice start instruction. For example, the second talk burst request may carry a terminal identifier of the DMR terminal.

And S612, the POC gateway returns the speaking right authorization indication aiming at the second speaking right application request to the transfer platform gateway under the condition that the transfer platform gateway is confirmed to be initiated to have the speaking right authorization condition.

When the POC gateway detects that the talk right in the public network POC system is not occupied, it may authorize the talk right for the transit station gateway or the DMR terminal initiating the voice start instruction.

S613, the transit platform gateway determines that the DMR terminal sending the voice start indication has the talk right authorization of the POC gateway, and receives the voice message packet sent by the DMR terminal.

And S614, the relay platform gateway forwards the voice message packet sent by the DMR terminal to the POC gateway so as to forward the voice message packet to the POC terminal through the POC gateway.

The steps S613 and S614 are similar to the previous steps S513 and S514, and are not described again.

In the following, a scenario will be described in which the public POC system is a communication system with a talk right, and the private DMR conventional system is a communication system without talk right control, and a DMR terminal in the private DMR conventional system initiates a call request to a POC terminal in the public POC system.

For example, referring to fig. 7, which shows another flow interaction diagram of a talk right control method according to the present application, the method of this embodiment may include:

s701, the DMR terminal initiates a group calling request to a relay station gateway of a private network DMR conventional system.

The group call request is at least for requesting a call to at least one POC terminal in the public network POC system. For example, the group call request may carry a group identifier of a group in which the terminal requesting the call is located.

S702, the relay station gateway responds to the group calling request and establishes session connection with the DMR terminal.

S703, the transit platform gateway responds to the group calling request, and sends a calling invitation to the POC gateway of the public network POC system to request to establish the session connection between the POC gateway and the transit platform gateway.

It is understood that, if the called party of the group call request includes other DMR terminals in the private network DMR conventional system, the transit gateway further sends a call invitation to the other DMR terminals so that the other DMR terminals establish a session connection, as shown by the dashed arrow in fig. 7.

S704, the POC gateway establishes a session connection between the POC gateway and the transit gateway in response to the call invitation.

S705, the POC gateway sends a call invitation to the POC terminal requesting the group call request to establish a session connection with the POC terminal.

S706, the POC terminal responds to the call invitation sent by the POC gateway, and establishes the session connection between the POC terminal and the POC gateway.

It can be understood that the above steps S701 to S706 belong to an interaction part of control plane signaling, and a specific implementation process thereof is similar to the process of establishing a session connection in steps S501 to S506 in the embodiment of fig. 5, and is not described herein again.

The above steps S701 to S706 are described by taking the DMR terminal to initiate the group call request as an example, but it can be understood that the same is also applicable to the embodiment if the DMR terminal initiates the individual call request.

S707, if the transit platform gateway confirms that the POC gateway and the transit platform gateway establish the session connection for the call request, then confirm that the DMR terminal has the talk right authorization for the group call request, and receive the voice start instruction sent by the DMR terminal.

It can be understood that, in the case that the conventional system of the private network DMR does not have the talk right, the DMR in the conventional system of the private network DMR does not need to send a request for applying the talk right to the transit gateway of the conventional system of the private network DMR, and therefore, in the case that the transit gateway confirms that the transit gateway establishes the session connection with the POC gateway, the transit gateway can confirm that the DMR terminal has the right to send the voice message packet to the POC terminal. In this case, the transit gateway processes the voice-related message packet sent by the DMR terminal to the POC terminal.

S708, the transit gateway forwards the voice start indication to the POC gateway, so as to forward the voice start indication to the POC terminal through the POC gateway.

The voice start instruction carries a group identifier corresponding to a group call request initiated by the DMR terminal.

S709, the transit platform gateway forwards the voice message packet sent by the DMR terminal to the POC gateway, so that the POC gateway forwards the voice message packet to the POC terminal that establishes session connection with the POC gateway.

It is understood that, in this embodiment of the present application, after step S709, the transit gateway may further receive the end-of-speech indication sent by the DMR terminal, and forward the end-of-speech indication to the POC gateway, so as to forward the end-of-speech indication to the POC terminal through the POC gateway. Of course, the transit platform gateway may also generate the voice end instruction and send the voice end instruction to the POC gateway when the specified duration does not receive the voice message packet sent by the DMR terminal.

Correspondingly, if the transit platform gateway confirms that the DMR terminal receives or generates the end-of-speech instruction, the transit platform gateway confirms that the DMR terminal ends the call, and then releases the talk right of the DMR terminal.

S710, when the transit gateway and the POC gateway establish the session connection, the POC gateway receives a second right application request sent by the POC terminal.

It can be understood that, since the public network POC system belongs to the communication system with the talk right, the POC terminal needs to apply for the talk right application request to the POC gateway first, and since the public network POC system in the embodiment of the present application is equivalent to the second communication system mentioned in the foregoing embodiment, the talk right application request sent by the POC terminal to the POC gateway is referred to as the second talk right application request.

It can be understood that, because of the group call request initiated by the POC terminal, the second talk right application request may request to obtain the talk right authority of the group to which the group call request corresponds to call, and thus, the second talk right application request at least requests to obtain the talk right of the DMR terminal that initiates the group call request.

S711, the POC gateway forwards the second right application request to the transit gateway.

S712, the transit platform gateway returns the talk right authorization indication for the second talk right application request to the POC gateway when confirming that the POC terminal initiating the second talk right application request has the talk right authorization condition.

S713, the POC gateway forwards the talk burst authority indication for the second talk burst application request to the corresponding POC terminal.

After receiving the talk right authorization indication, the POC terminal initiating the second talk right application request has the right to send the voice message packet to the DMR terminal under the control of the transit platform gateway.

S714, the POC gateway forwards the voice message packet sent by the POC terminal with the talk right authorization to the relay gateway, so as to forward the voice message packet to the DMR terminal corresponding to the voice message packet through the relay gateway.

The application also provides a speaking right control device corresponding to the speaking right control method.

For example, referring to fig. 8, it shows a speaking right control device of the present application, applied to a first gateway of a first communication system, and including:

a call receiving unit 801, configured to receive a call request initiated by a first terminal of a first communication system, where the call request is used to request a call to at least one second terminal in a second communication system;

a session requesting unit 802, configured to request, in response to the call request, a second gateway of the second communication system to establish a session connection for the call request;

In a possible implementation manner, the first floor authorization unit may include:

in yet another possible implementation manner, the first floor authorization unit may include: a second authorization subunit, configured to determine that the first terminal has a talk burst authorization for the call request.

Optionally, the apparatus may further include:

a voice forwarding unit, configured to forward, after the first talk right authorization unit allocates a talk right authorization for the call request to the first terminal, a voice message packet sent by the first terminal to the second gateway, so as to forward, through the second gateway, the voice message packet sent by the first terminal to the at least one second terminal;

and the speaking right releasing unit is used for releasing the speaking right of the first terminal under the condition that the first terminal is confirmed to end the call.

an application receiving unit 804, configured to receive a second right application request sent by a second gateway under a condition that the session connection established between the first gateway and the second gateway is maintained, where the second right application request is generated by the second gateway in response to a right application request or a voice start instruction sent by a target second terminal, where the target second terminal belongs to the at least one second terminal, and the right application request or the voice start instruction sent by the target second terminal is used to request a callback for the call request;

a second talk right authorizing unit 805, configured to send, in response to the second talk right applying request, a talk right authorization for the second talk right applying request to the second gateway under the condition that it is determined that the second gateway has the talk right authorization, so that the second gateway determines that the target second terminal obtains the talk right authorization of the first gateway.

Optionally, in an embodiment of any of the above apparatuses, the call receiving unit may include:

a call receiving unit, configured to receive a call request initiated by a first terminal of the first communication system, where the call request is used to request to call a second terminal of the second communication system;

and the calling authorization subunit is used for distributing the speaking right authorization aiming at the calling request to the first terminal.

In another possible implementation manner, the call receiving unit includes:

a group call receiving unit, configured to receive a group call request initiated by a first terminal of the first communication system;

the apparatus may further include:

an internal session establishing unit, configured to establish a session connection between the first gateway and the first terminal before the session requesting unit requests, to a second gateway of the second communication system, establishment of a session connection for the call request.
