Description

State transition method for user terminal and server, and user terminal and server

The present invention relates to the field of communications, and in particular, to a state transition method for a user terminal and a server, and a user terminal and server.

Background of the invention

With the development of broadband networks, mobile communications will not only be limited to traditional voice communications, but multimedia services combining multiple media types such as audio, video, pictures and text will gradually be developed. The multimedia service can be combined with presence (presentation service), short message, TOB (web) browsing, location information, PUSH (push service) and file sharing to provide users with a variety of business services. The various business services include:

Messaging business: instant messaging and chat rooms, multimedia short messages, etc.

Video business: entertainment, multimedia information, daily communication, etc.

E-commerce: product catalogs, search engines, shopping carts, order management, payments, etc.

Games: Single player games, group games, etc.

Positioning business: tracing people, guides, alarms, etc.

Personal Assistant: Address Book, Calendar, Bookmark Management, File Storage, Event Reminder, Email, etc.

Driven by the various business service applications described above, the 3GPP (Third Generation Partnership Projects) standards organization has introduced an IP-based IMS (Internet Multimedia Subnet) architecture with the goal of using a standardized open architecture in communication networks. To achieve a variety of multimedia applications, to provide users with more choices and richer feelings.

With the development of network technology, multi-party communication has become an increasingly common service. In order to achieve multi-party communication, it is necessary to have a unified control point to manage the system, and it is necessary to ensure the consistency and real-time management. For example, when a user requests to send audio data, the system needs to have one and only one control point to process the application. Current multi-party multimedia communication systems include PoC (Cellular Push-to-Talk) systems, Conference (Multimedia Conference) systems and the like. The PoC system is a centralized multi-party multimedia communication system.

In the multi-party multimedia communication system, there is a call right management of the user terminal, that is, the user terminal can apply for transmitting media data, and the system can limit the length of time for the user terminal to send the media data. The user terminal includes a cluster client.

A schematic diagram of a state machine of a user terminal in the prior art is shown in FIG. 1. The state transition method of the user terminal is: when the user terminal receives the floor granted (message transmission permission) sent by the system in the waiting for request state, Enter the Permitted status. According to the state transition state of the state machine, if the user terminal applies for transmitting media data, the user terminal immediately starts to send media data; if the user terminal applies for transmitting voice data, the user terminal starts to send the received voice data. Give the server.

As shown in Figure 1, if the user terminal is in the No Permitted state, it cannot directly go to the Permitted state. Instead, it must first migrate to the media transmission right waiting request status by sending a media transmission right request message, and then wait for it. After receiving the oor granted message in the request state, it moves to the Permitted state.

In a multi-party multimedia communication system, there is a need for a third party to apply for a media transmission right. For example, Client A applies for Client B. Client A sends a media transmission right request to the cluster server. The request indicates to Client B to apply for the media transmission right. After the cluster server obtains the request, if the application is approved, the client directly sends the request to the client. B sends floor granted That is, the media transmission right is granted to the client B. At this time, the client B cannot process the floor granted message because there is no corresponding state to be converted, and the floor granted message may be considered as an abnormal message and discarded.

A disadvantage of the state transition method of the prior art user terminal is that: In the method, after the user terminal receives the floor granted message in the waiting for request state, the user enters the Permitted state. At this time, the user terminal immediately starts to transmit the media data, and the user terminal cannot select to transmit data or refuse to transmit data according to the actual situation. Because, at this time, the user who operates the user terminal may not be next to the user terminal, or the user terminal is not ready to send media data. In the above case, the user terminal does not want to immediately transmit data. In this method, the user terminal cannot achieve this.

In this method, the user terminal cannot directly transfer from the No Permitted state to the Permitted state; the requirement for the third party to apply for the media transmission right cannot be realized.

The embodiment of the present invention provides a state transition method for a user terminal and a server, and a user terminal and a server. After receiving a media transmission right grant message sent by the server, the user terminal enters an intermediate state. Waiting for the operation of the user who operates the terminal, and then, according to the operation of the user, the user terminal performs a corresponding state transition.

The embodiment of the present invention is described in detail below with reference to the accompanying drawings. FIG. 2 is a schematic diagram of the state machine of the state transition method of the user terminal according to the embodiment of the present invention. The difference between the state machine and the prior art is to increase. A Pending Indication status.

Pending Indication state: When the user terminal receives the floor Granted message sent by the system, whether it is waiting for the request status or No Permitted status, the user terminal enters the state. In this state, the user terminal does not immediately perform media data transmission, and waits for the operation of the user who operates the user terminal. The user may select to transmit media data or refuse to transmit media data according to actual conditions.

After the Pending Indication state is added, the process flow of the state transition method of the user terminal according to Embodiment 1 of the present invention is as shown in FIG. 3, and includes the following steps:

S310. The PoC Client applies for the media transmission right through some means. For example, if the PoC Client user applies for the media transmission right, or the other PoC Client user applies for the media transmission right for the PoC Client user, the user will receive the floor. Granted message, then, the user enters the Pending Indication state.

The S320 and the PoC Client notify the user who operates the PoC client by ringing, flashing, etc., that is, the media transmission right is presented to the user who operates the PoC Client, and the confirmation timer Tc is started.

S330, determining whether the user operating the PoC Client accepts the media transmission right before the confirmation timer Tc times out, if yes, the process proceeds to step S340, otherwise proceeds to step S370; S340. Send a Floor granted ACK message to the server.

The user terminal transmits a floor granted ack (message transmission right acknowledgement) message to the server when the user selects before the confirmation timer Tc times out or the user sets to accept the granted media transmission right.

This step is optional, and the Floor granted ACK message may not be sent. If not sent, the server can confirm that the PoC Client user has accepted the media transmission right by receiving the media stream.

In the above process, the acceptance may be an interactive confirmation by the PoC Client user, or may be accepted by the preset setting, for example, it is preset to always accept the media transmission right granted by the third party.

S350. The state machine of the PoC Client migrates from a pending indication state to a permitted state.

S360 and POC Client send media data normally.

S370. If the user operating the PoC Client does not confirm or reject the media sending right before the timer Tc expires, the state machine of the PoC Client migrates from the pending indication state to the not permitted state. Then, the PoC Client sends a floor release (message transmission right release) message to the server.

The Floor Ack message in the above process is a newly added media control message for confirming the acceptance of the media transmission right to the server; the message, like other media control messages, may be based on the RTCP message extension. After the Pending Indication state is added, the PoC Client A in the embodiment of the present invention requests the media to send the right. The process of the PoC Client B accepting the media transmission right is as shown in FIG. 4, and includes the following steps:

S410, Client A sends a Floor req (media transmission right request) to the server, and applies for a media transmission right for the client B. S420, the cluster server sends a Floor Granted message to the client B, and informs the application media transmission right event; S430, the cluster server sends Client A sends a Floor Taken message to inform the media that the right to send the application is accepted;

S440, the cluster server starts the timer Tx waits for the client B to respond;

S450, Client B prompts the user of the Client B to confirm the media transmission right, and starts the timer Tc, waiting for the response of the user who operates the Client B;

S460. Client B confirms acceptance before the timer Tc expires or the Client B user is set to accept the media transmission right. S470. Client B sends a Floor Granted ACK message to the cluster server, and confirms that the media transmission right is accepted. This step is optional. Client B can also directly perform step S480.

S480. Client B sends media stream data to the cluster server.

S490. The cluster server sends the received media stream to Client A.

Note - In general, it is recommended that the timer Tc started at the terminal should be less than the timer Tx started by the cluster server. If the Tx is 5 seconds, the timer Tc initiated by the terminal should be less than 5 seconds.

The application of the above improved state machine of the user terminal in the 0MA P0C (Object Management Structure Based on Cellular Click-to-Talk) specification is shown in FIG.

Corresponding to the state transition method described in the foregoing embodiment 1, the embodiment 1 of the present invention further provides a user terminal. The structure of the user terminal is as shown in FIG. 6, and includes the following modules:

The waiting indication state setting unit is configured to migrate to the waiting indication state after the user terminal receives the floor Granted message. Waiting for a user operation unit, for prompting the media transmission right to the user operating the user terminal, waiting for the operation of the user terminal After the user performs the corresponding operation, the user operation result is transmitted to the state transition unit.

And a state transition unit, configured to migrate the state of the user terminal to a permission transmission state or a license transmission state according to the user operation result of the waiting user operation unit transmission.

The media sending right request unit is configured to apply for a media transmission right to the server for itself or other user terminals.

The waiting user operation unit specifically includes:

The media sending right prompting unit is configured to prompt the user who operates the user terminal to send the media right after the user terminal migrates to the waiting indication state.

a timer unit, configured to receive a media transmission right setting time threshold for a user operating the user terminal;

The user operation result processing unit is configured to receive an operation result of accepting/rejecting the media transmission right selected by the user operating the user terminal, and transmitting the operation result to the state migration unit.

The state transition unit specifically includes:

The license transmission status setting unit is configured to migrate the state of the user terminal to the permission transmission state after the user operating the user terminal accepts the media transmission right.

There is no permission transmission status setting unit for migrating the state of the user terminal to the state without permission transmission after the user operating the user terminal does not accept the media transmission right.

The media transmission right release message sending unit is configured to send a floor release (media transmission right release) message to the server after the state of the user terminal migrates to the state without the permission to send. FIG. 7 is a schematic diagram of Embodiment 2 of a state machine of a state transition method of a user terminal according to an embodiment of the present invention. The state machine differs from the prior art in that the Pending Indication state is a substate of a Permitted state (or The internal state exists, that is, the new state is not added to the state machine of the existing user terminal, and only a new event processing process is added to the Permitted state of the existing user terminal. There are two sub-states in the Permitted state: the user has confirmed the Floor and the user has not confirmed the Floor (that is, waits for the indication status). The two states can be implemented by setting an internal identifier UserConfirmFlag. The value of UserConfirmFlag is: "User Confirming" or "User Confirmed" is used to distinguish between two substates.

After the Pending Indication state is a sub-state of the Permitted state, the process flow of the state transition method of the user terminal according to Embodiment 2 of the present invention is as shown in FIG. 8, and includes the following steps:

After the S810 and the PoC Client apply for the media transmission right through some means (for example, the PoC Client user applies for the media transmission right, or the other PoC Client user applies for the media transmission right for the PoC Client user), the user will receive the floor Granted. The message, then, the user enters the Permitted state.

S820, PoC Client sets UserConfirmFlag to User Confirming, that is, the user does not confirm the floor (waiting for indication status), and the media transmission right is prompted to the user who operates the PoC Client and starts the timer Tc;

S830, the PoC Client determines whether the user operating the PoC Client accepts the media transmission right before the timer Tc times out; if the process proceeds to step S840, otherwise proceeds to step S860;

S840, setting UserConfirmFlag to User Confirmed, that is, entering the user-to-floor confirmed state; if the PoC Client user accepts the media sending right before the timer Tc times out, setting UserConfirmFlag to User

Conf irined. The PoC Client user's acceptance of the media transmission right in this step may be an interactive confirmation by the PoC Client user, or may accept the media transmission right through a preset setting, for example, pre-set to not accept the media transmission right granted by the third party, then PoC Client always refuses the right to send media from third parties;

The S850 and PoC Client send media normally.

S860. If the user of the PoC Client does not confirm or reject the media sending right before the timer Tc expires, the state machine of the PoC Client will migrate from the permitted state to the not permitted state. Then, the PoC Client sends a floor release message to the server.

Note - In general, it is recommended that the timer Tc started at the terminal should be less than the timer Tx started by the cluster server. If it is 5 seconds, the timer Tc of the terminal should be less than 5 seconds.

Corresponding to the state transition method described in Embodiment 2, Embodiment 2 of the present invention further provides a user terminal. The structure of the user terminal is as shown in FIG. 9, and includes the following modules:

The state transition unit is configured to migrate the state of the user terminal to a user confirmed state in a non-permitted transmission state or a permission transmission state according to a selection result of a user waiting for the user operation unit to transmit.

The media sending right requesting unit is configured to apply for a media sending right to the server for the user terminal or other user terminal.

The waiting user operation unit specifically includes:

a media sending right prompting unit, configured to prompt a user who operates the user terminal to send a media right after the user terminal migrates to the waiting indication state;

The user operation result processing unit is configured to receive a selection result of accepting or rejecting the media transmission right returned by the user operating the user terminal, and transmitting the selection result to the state transition unit.

The state transition unit specifically includes:

a user confirmed status setting unit, configured to migrate the state of the user terminal to the user confirmed state in the permission sending state after receiving the selection result of the receiving media transmission right returned by the user operating the user terminal;

There is no permission transmission status setting unit, configured to migrate the state of the user terminal to the non-permission transmission state after receiving the selection result of rejecting the media transmission right returned by the user operating the user terminal;

The media sending right release message sending unit is configured to send a media sending right release message to the server after the state of the user terminal migrates to the state without the permission to send. The state machine of the system server is also improved in the embodiment of the present invention. The state machine of the system server according to the embodiment of the present invention is as shown in FIG. The difference between this state machine and the prior art is the addition of a Pending Confirm status.

Pending Confirm Status: When the server sends a floor grant message to the user terminal, the server enters the Pending Confirm state from the Floor taken status and starts the monitoring response timer. The Pending Confirm status of the server will trigger a state transition according to different conditions:

After the server receives the floor granted ack message sent by the user terminal, or after receiving the media data sent by the user terminal, the server state machine will migrate from the Pending Confirm state to the Floor taken (media transmission right allocation) state;

After receiving the floor release message sent by the user terminal, or after receiving the message and data sent by the user terminal, the server stops the timing of the monitoring response timer and sends the message to the user terminal. The foor free message, the server state machine will migrate from the Pending Confirm state to the Idle state.

Corresponding to the state machine shown in FIG. 10, the embodiment of the present invention further provides a server. The structure of the server is as shown in FIG. 11, and includes the following module - a waiting confirmation status setting unit, for the server to the user terminal. After the floor granted message is sent, the state of the server is migrated to the Pending Confirm state.

The media transmission right allocation state setting unit is configured to: after receiving the floor granted ack message sent by the user terminal, or after receiving the media data sent by the user terminal, migrating the state of the server from the Pending Confirm state to the Floor taken state .

The idle state setting module is configured to: after receiving the floor release message sent by the user terminal, or after receiving the set time, the message or media data sent by the user terminal is not received, and the speaker is sent to the user terminal. The Send Right Idle message, which migrates the state of the server from the Pending Confirm state to the idle state.

The timer unit is configured to receive a media transmission right setting time threshold for the user operating the user terminal, and after receiving the floor release message or the media data sent by the user terminal, the server stops counting the monitoring response timer. The above Pending Confirm state can also exist as a substate (or internal state) of the Floor Taken state, that is, it does not add a new state to the state machine of the existing server, and only adds new event processing to the existing server's Floor Taken state. process. When the Pending Confirm state is a substate of the Floor Taken state, a schematic diagram of the server's state machine is shown in Figure 12. The specific processing procedure when the state machine of the user terminal is in the Permitted state is as follows:

When the server sends the Send Floor Granted, it migrates from the Idle state to the Floor Taken state. In the Floor Taken state, there are two substates inside, Floor confirmed and Floor unacknowledged (that is, Pending Confirm state). The two states can pass. Set an internal identifier to achieve.

When the server status is migrated from Idle to Floor Taken, the initial state of the server's Floor Taken state is Floor unacknowledged. At this time, the floor Granted ack message or the floor release message or the media data (Receive Data) can be processed. When the server receives the user terminal, it sends the message. After the floor granted ack message or media data, the substate of Floor Taken is confirmed from the unconfirmed migration of Floor to Floor.

After the server receives the floor release message sent by the user terminal, or does not receive the message sent by the user terminal after the time of the set time arrives, the server stops the timing of the monitoring response timer, and sends floor free to the user terminal. Message, the server state machine will migrate from the Floor Taken state to the Idle state.

Corresponding to the state machine shown in FIG. 12 above, the embodiment of the present invention further provides a server, and the structure of the server is as shown in the figure. 13, including the following modules:

The media transmission right unacknowledgment status setting unit is configured to migrate the state of the server to the Floor unconfirmed state in the Floor Taken state after the server sends the floor granted message to the user terminal.

The media transmission right confirmed status setting unit is configured to: after receiving the floor granted ack message sent by the user terminal, or after receiving the media data sent by the user terminal, the status of the server is from the Floor of the Floor Taken state. Confirm that the status has been migrated to the Floor confirmed status in the Floor taken state.

The idle state setting module is configured to: after receiving the floor release message sent by the user terminal, or after receiving the set time, the message or media data sent by the user terminal is not received, and the floor free is sent to the user terminal. The Send Right Idle message, which migrates the state of the server from the Floor unacknowledged state in the Floor Taken state to the idle state.

The timer unit is configured to receive a media transmission right setting time threshold for the user operating the user terminal, and after receiving the floor release message or the media data sent by the user terminal, the server stops counting the monitoring response timer. After the state machine of the user terminal and the server is applied, the processing flow of the embodiment of the method for transmitting data by the user terminal in the embodiment of the present invention is as shown in FIG. 14 , and includes the following steps:

Step 14-1: After the server detects the user terminal, the server sends a floor granted message to the user terminal.

After the server receives an indication of floor authorization for a user terminal; or, the server receives a floor authorization request of a user terminal; or, the server receives a floor authorization request from the other user terminal to the specified user terminal. After that; or, the server decides to perform floor authorization for a user terminal based on other mechanisms.

Then, the server detects the user terminal, and after confirming that the user terminal can perform the media transmission right authorization, the server sends a floor granted message to the user terminal.

Step 14-2: After receiving the floor granted message sent by the server, the user terminal does not immediately send data, enters the Pending Indication state, and waits for the user's operation.

After the user terminal receives the floor granted message sent by the server, the user terminal does not immediately send data, and enters the Pending Indication state. The user terminal notifies the user who operates the user terminal by ringing, flashing, etc., and waits for the operation of the user.

At the same time, the server also enters the above Pending Confirm state and starts the timing of the monitoring response timer.

Step 14-3: The user terminal selects to send data or refuse to send data according to the actual situation in the Pending Indication state, and performs corresponding processing.

After the user terminal enters the Pending Indication state, the user terminal does not immediately perform data transmission, and waits for the operation of the user operating the user terminal. The user may select to send data or refuse to send data according to actual conditions.

A schematic diagram of the user terminal transmitting a floor granted ack message to the server or directly transmitting data is shown in FIG. When the user selects to send data, after the user terminal sends the floor granted ack message to the system, the user terminal enters the Permitted state, and then the user terminal performs data transmission; or, the user terminal directly enters the Permitted state, and the user terminal directly performs data transmission. . When the server receives the above floor granted ack message or receives the data sent by the user terminal, it stops the timing of the monitoring response timer and enters the floor taken state.

If the user terminal applies for transmitting media data, the user terminal immediately starts to send the media data; if the user terminal applies for When the voice data is transmitted, the user terminal starts to send the received voice data to the server.

A schematic diagram of the user terminal sending a floor release message to the server is shown in FIG. 16.

When the user chooses to refuse to send data, the user terminal sends a floor release message to the server. After receiving the floor release message sent by the user terminal, the server stops the timing of the monitoring response timer, sends a floor free message to the user terminal, and reclaims the floor authorization for the user terminal. The server enters the Idle state, and the user terminal enters the Not Permitted state.

The schematic diagram of sending a floor free message (or floor release) to the user terminal after the timer of the server's monitoring response timer expires is shown in FIG. 17.

The purpose of the Floor free message is to notify the cluster server user terminal to abandon the media transmission right. Therefore, this message can re-construct a message or use the existing floor release message that rejects or releases the floor.

When the user chooses to refuse to send data, the user terminal may also not send a message to the server. After the set time has elapsed, the server does not receive a response message from the user terminal. At this time, the timing of the above monitoring response timer expires. The server stops the timing of the monitoring response timer, sends a floor free message to the user terminal, reclaims the floor authorization to the user terminal, the server enters the Idle state, and the user terminal enters the Not Permitted state.

When the floor authorization of the above user terminal is reclaimed, the server will broadcast a floor free notification message, notifying that the floor is still in a free state. Alternatively, the server performs floor authorization processing for the next user terminal according to a specific processing situation (such as a support queue).

In summary, the embodiment of the present invention adds a Pending Indication state to the state machine of the user terminal by modifying the state machine processing of the user terminal and the system server, and adds a Pending Confirm state to the state machine of the system server, thereby enabling the user terminal. After receiving the floor Granted message, you can choose to send media data or refuse to send media data according to user operations. The operability of the user is increased, and the problems of the prior art described above are effectively solved.
