Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and a device for sending and receiving a high priority service in a direct mode.
Background
The DMR (Digital Mobile Radio) protocol is a new communication protocol suitable for Digital trunking communication systems, and employs a TDMA (Time Digital multiple access) structure with 2 slots, as shown in fig. 1, where each burst contains two slots, each slot is 30ms, and each burst is 60 ms. The purpose is to achieve two-way calling using two timeslots at 12.5KHz bandwidth, thereby achieving a true 6.25KHz bandwidth channel efficiency.
The DMR protocol includes two modes, direct (i.e., not transmitted through the relay station) and forward. One mode of operation of the direct mode is that the intercom can only use one timeslot to implement a call when transmitting, and the other mode of operation is the reverse channel mode. As shown in fig. 2, in the reverse channel mode, the intercom MS2 receiving in time slot 1 may send back a reverse burst signaling to the transmitting intercom MS1 through time slot 2. The reverse burst (the portion indicated by the oblique lines in fig. 2) is only a relatively short frame, and cannot be used to transmit audio signals, and it is only some status data to inform the transmitting interphone of the current receiving state of the interphone. In this case, for some high priority services, such as short message service or call service, the intercom in the transmitting state cannot receive the high priority service.
Disclosure of Invention
The embodiments of the present invention provide a method and a device for sending and receiving a high priority service in a direct mode, so that a user terminal in a transmitting state in the direct mode can also receive the high priority service.
Therefore, the embodiment of the invention provides the following technical scheme:
a method for sending high priority service in a direct mode includes:
a user terminal receives an instruction of a user for sending a high-priority service;
generating a priority frame and a high-priority service frame according to the instruction, wherein the priority frame is used for enabling a receiver to identify the high-priority service according to the priority frame;
and transmitting the priority frame and the high-priority service frame.
A method for receiving high priority service in a direct mode comprises the following steps:
after a user terminal sends a voice frame in a voice call sending state, receiving a detection priority frame in another time slot relative to the time slot occupied by the voice call;
if the priority frame is detected, the voice call is stopped, and the high priority service frame is received in the other time slot.
A high priority traffic sending device in a pass-through mode, comprising:
the instruction unit is used for receiving an instruction of a user for sending a high-priority service;
a frame generating unit, configured to generate a priority frame and a high-priority service frame according to the instruction, where the priority frame is used to enable a receiving party to identify the high-priority service according to the priority frame;
and the sending unit is used for sending the priority frame and the high-priority service frame.
A high priority traffic receiving device in a pass-through mode, comprising:

a control unit, configured to notify the sending unit to stop the voice call after the receiving detection unit detects the priority frame;
a receiving unit, configured to receive the high priority traffic frame in the another timeslot.
In the method and the device for sending the high-priority service in the direct mode, in order to enable a high-priority service receiver to identify the high-priority service, the user terminal sends the priority frame before sending the high-priority service frame, so that the high-priority service receiver can identify the high-priority service by detecting the priority frame no matter the high-priority service receiver is in a voice receiving state, a channel monitoring state or a voice sending state, and the priority receiving and processing of the high-priority service are ensured. Accordingly, the method and apparatus for receiving a high priority service in a direct mode according to embodiments of the present invention monitor another non-transmission timeslot for a user terminal in a voice call transmission state, stop the voice call once a priority frame is detected in another timeslot, and receive the high priority service in a corresponding timeslot, so that the user terminal accesses the high priority service preferentially. The time for detecting and identifying the priority frame by the user terminal in the embodiment of the invention is very short (not more than 10ms), the transmitted voice can not be interrupted, and once the transmitted voice call is detected, the user terminal participating in the conversation can receive the short message or the call with high priority. By using the priority frame, the user terminal can receive in a short time when in a transmitting state, and meanwhile, the transmission is not influenced, thereby realizing seamless switching from transmitting to receiving of high-priority services.

Detailed Description
In order to make the technical field of the invention better understand the scheme of the embodiment of the invention, the embodiment of the invention is further described in detail with reference to the drawings and the implementation mode.
To facilitate understanding of the scheme of the present invention, a brief description of the general data frame format defined in the existing DMR standard is first provided below.
As shown in fig. 3, a Data type in a timeslot type PDU (Protocol Data Unit) is used to display a type of Data or a control frame carried by a general Data frame, and two sides 196 bits of information are a payload carried by the Data type and error correction information thereof. The content definition of the data type is shown in table 1.
Table 1:
in order to enable a user terminal in a transmitting state in a direct mode to receive a high-priority service, where the high-priority service refers to a service such as a relatively urgent text message or a voice call, in the method for sending the high-priority service in the direct mode according to the embodiment of the present invention, for the user terminal in a voice call receiving state, another idle timeslot of the user terminal is used to send the high-priority service, and in order to distinguish the user terminal from a normal service, a service frame of the high-priority service is referred to as a high-priority service frame. Also, in order for the high priority traffic receiver to be able to recognize the high priority traffic, a priority frame is transmitted before a high priority traffic frame is transmitted. Accordingly, the high priority service receiving method in the direct mode according to the embodiment of the present invention monitors another non-transmission timeslot for the user terminal in the voice call sending state, stops the voice call once a priority frame is detected in another timeslot, and receives the high priority service in the corresponding timeslot, so that the user terminal accesses the high priority service preferentially.
The priority frame may adopt a data frame format defined in the DMR standard, and a new data type is added on the basis of the existing data frame format to distinguish the priority frame. Of course, the embodiments of the present invention are not limited to the data frame format of the DMR standard, and may also be applied to various communication environments supporting TDMA, except that the data frame format is slightly different.
There may be one or more (including two or more) priority frames, and the embodiment of the present invention is not limited thereto. In consideration of the detection accuracy and overhead, in practical application, two priority frames may be preferentially adopted, and for convenience of description, the two priority frames are referred to as: the first priority frame PB1 and the second priority frame PB2, and PB1 and PB2 may be the same or different.
The priority frames PB1 and PB2 may be defined by data type reservation values in the DMR protocol, for example, the data type definitions of the above priority frames PB1 and PB2 are shown in table 2 below.
Table 2:
the PDU structure of the priority frame may be defined by itself, or a PDU structure similar to CSBK may be adopted, as shown in fig. 4.
Wherein, the meaning of each block in fig. 4:
LB (last Block) represents the last block flag;
pf (protect flag) indicates a protection flag;
CSBKO (control Signalling Block opcode) represents the control signaling operation code;
fid (feature Set ID) represents a function identification ID;
DATA represents DATA information, and may include a source address, a destination address, and the like;
CSBK CRC (Control Signalling Block Cyclic Redundancy check) represents the Cyclic check code of Control signaling Block;
octet (Octet)2 ~ 9 fields and 6 bits CSBKO, the user can carry out the design by oneself as required.
It should be noted that, if there is no activity on the channel, the manner and procedure of sending the high priority service by the ue may be the same as the manner and procedure of sending the normal call in the prior art. However, when there is a voice call on the channel, the method for sending a high-priority service in the direct mode according to the embodiment of the present invention may send the high-priority service in another idle timeslot other than the receive timeslot.
As shown in fig. 5, a flow of a method for sending a high-priority service in a direct mode according to an embodiment of the present invention includes the following steps:
The priority frame may adopt a data frame format defined in the DMR standard, and add a new data type to an existing data frame format or use a reserved value of an existing data type to indicate that the frame is a priority frame. Of course, if there are multiple priority frames, they may be distinguished by different data type values.
The high-priority service frame may adopt a general data frame format defined in the existing DMR standard.
It should be noted that, when the priority frame and the high priority traffic frame are transmitted, the ue may be in a voice call receiving state or in an idle state. If the voice call is in a voice call receiving state, the voice call is required to be stopped from being received, and then the priority frame and the high-priority service frame are sent in another idle time slot except the receiving time slot; if in the idle state, the priority frame and the high priority traffic frame may be transmitted in an optional time slot, such as by default on the first time slot.
In the embodiment of the present invention, the high priority service may be a voice call service, a text message service (such as short message service, multimedia message service), and the like.
In addition, in practical applications, if a high priority service is addressed to a single person, confirmation by the recipient may be required; if the message is addressed to multiple people, no confirmation may be required. The receiver may determine whether a response frame needs to be sent back according to the received call type. Therefore, if the high-priority service requires the confirmation of the receiving party, for example, a high-priority short message with confirmation is sent, the user terminal switches to a receiving state after the transmission of the high-priority service frame is finished, starts a waiting response timer, and waits for a response frame sent by the receiving party. If the response frame is received in the idle slot within a preset time (timer time), the ue may display a prompt message indicating that the transmission is successful, such as "sms is successful |)! "etc. information so that the user of said user terminal knows whether the short message has been successfully sent to the receiving party.
In addition, for the short message service with high priority, the user terminal may also display the prompt information of successful transmission after the transmission of the high priority service frame is finished.
In practical application, in order to enable a user terminal to identify whether a service sent by a user is a normal service or a high-priority service, a menu editing mode or a selectable panel control mode or other modes can be provided for the user to select, the user terminal determines whether the service needing to be sent is the high-priority service according to the selection of the user, if the service is the high-priority service, the priority frame is generated and sent, otherwise, the priority frame is not required to be generated and sent.
Certainly, in some application scenarios, for example, users in a cluster may have different levels of permissions, and a user with a high permission may interrupt a call of a user with a low permission. The service class indication information may be indicated by a data type in a PDU structure of the priority frame, and of course, may also be indicated by other manners, which is not limited in this embodiment of the present invention.
It should be noted that, in this embodiment, the user terminal may be any terminal device having an intercom function, such as a handheld intercom, a vehicle-mounted car station, and the like.
Therefore, in the method for sending a high-priority service in the direct mode according to the embodiment of the present invention, in order to enable a high-priority service receiver to identify the high-priority service, before sending a high-priority service frame, a priority frame is sent first, so that the receiver can correctly detect the priority frame, and thus preferentially receive the high-priority service.
Correspondingly, the embodiment of the invention also provides a method for receiving the high-priority service in the direct mode, which not only can realize call interruption, but also can enable the user terminal participating in the conversation to access the high-priority service preferentially.
As shown in fig. 6, it is a flowchart of a method for receiving a high priority service in a direct mode according to an embodiment of the present invention, and the method includes the following steps:
601, after sending a voice frame in a voice call sending state, a user terminal receives a detection priority frame in another time slot relative to the time slot occupied by the voice call;
Of course, if the priority frame is not detected, the user terminal may continue the current voice call.
It should be noted that, in step 601, the voice frame sent by the ue may be a normal service frame or a high priority service frame.
If the frame is a high-priority service frame, the user terminal needs to continue to detect the service level indication information in the priority frame after detecting the priority frame, and if the level of the high-priority service indicated by the service level indication information is higher than the level of the current voice call, the current voice call is stopped; otherwise, the current voice call may not be stopped. In the embodiment of the present invention, the high priority service may be a voice call service, a text message service (such as short message service, multimedia message service), and the like.
In addition, in the embodiment of the present invention, the method may further include the steps of:
and after the user terminal finishes receiving the high-priority service frame, displaying a prompt message of ending the high-priority service.
Moreover, if the high priority service is a high priority service requiring confirmation by the receiving party, such as a short message service, the method may further include the following steps:
and the user terminal sends a response frame in the other time slot after the high-priority service frame is received.
In addition, if the received high priority service is a short message service, the user terminal displays the received short message after the high priority service frame is received.
In practical application, in order to meet application requirements of users in different environments, a high-priority service function can be enabled through a configuration mode, and if the users need to be capable of preferentially receiving the high-priority service in a voice sending state, the function is started.
It should be noted that, in this embodiment, the user terminal may be any terminal device having an intercom function, such as a handheld intercom, a vehicle-mounted car station, and the like.
It can be seen that, in the high priority service receiving method in the direct mode according to the embodiment of the present invention, for a user terminal in a voice call sending state, the user terminal monitors another non-transmission timeslot, and once a priority frame is detected in another timeslot, the voice call is stopped, and the high priority service is received in a corresponding timeslot, so that the user terminal is preferentially accessed to the high priority service.
The following examples further describe in detail the specific application of the high priority service receiving method in the direct mode in different environments according to the embodiment of the present invention.
Example 1: user terminal participating in conversation receives high priority short message
If someone occupies the channel for a long time in the conversation process, the group administrator needs to send a short message to inform all group members in the group to execute a certain instruction under the emergency condition, including the group member sending the voice call, and the voice call which is being sent can be interrupted by enabling the user terminal to send the high-priority short message, so that all group members can receive the high-priority short message.
Assume that call group 1 has two members: user terminal a and user terminal C, a manager: the specific implementation process of the user terminal B is as follows:
1. configuring user terminal A and user terminal C to enable the function of receiving high-priority short messages, and user terminal B to enable the function of sending high-priority short messages.
2. User terminal a initiates a group call, group 1, group administrator user terminal B and group member user terminal C may all access the call.
3. The user terminal B of the group manager receives the short message of the upper level indication that the execution command needs to be sent to inform the user terminal A and the user terminal C of the group members. The user edits the short message through the menu or the selectable board of the user terminal B, and the user terminal B sends the priority frame and the edited short message to the group member of the calling group 1 through another idle time slot: user terminal a and user terminal C.
4. The user terminal A detects the priority frame in another non-transmission time slot, if so, the user terminal A stops transmitting the voice call and receives the short message following the priority frame.
The user terminal C finishes receiving the call of the user terminal A and starts to receive the high-priority short message sent by the user terminal B.
It should be noted that, for a ue that does not need to send a high priority service, it may monitor two timeslots simultaneously, so as to access the high priority service preferentially.
Example 2: user terminal participating in conversation receives high priority call
If someone occupies the channel for a long time in the conversation process, the group administrator needs to interrupt the speaker, so that the group members can hear the speech of themselves, and the user terminal can be enabled to send a high-priority call to interrupt the voice call being sent, so that all the group members start to receive new calls.
Assume that call group 1 has two members: user terminal a and user terminal C, a manager: the specific implementation process of the user terminal B is as follows:
1. user terminal a and user terminal C are configured to enable the receive high priority call function and user terminal B to enable the send high priority call function.
2. Group member user terminal a initiates a group call to group 1, and group administrator user terminal B and group member user terminal C may all access the call.
3. The group administrator wants to stop speaking at the user terminal a of the group member and makes a speech. The user presses PTT (Push-to-Talk) of the user terminal B, and initiates a group call to group 1 through another idle timeslot, and certainly, before sending the voice frame of the group call, a priority frame needs to be sent.
4. The user terminal A detects the priority frame in another non-transmission time slot, stops transmitting the call and receives the call initiated by the user terminal B in the non-transmission time slot.
The user terminal C finishes receiving the call of the user terminal a and starts receiving the high priority call of the user terminal B.
It should be noted that, for a user equipment that does not need to send a high priority service, it needs to monitor two timeslots simultaneously, so as to access the high priority service preferentially.
Example 3: user terminal in receiving state preferentially accesses high-priority short message
If there are two calls on one channel, one is ordinary voice call and the other is high priority short message, the receiving user terminal monitors two signals and accesses the high priority short message preferentially.
Assume that call group 1 has two members: user terminal a and user terminal C, a manager: the specific implementation process of the user terminal B is as follows:
1. configuring user terminal C to enable the function of receiving the high-priority short message, and configuring user terminal B to enable the function of sending the high-priority short message.
2. The group member user terminal a initiates a group call to which both the group administrator user terminal B and the group member user terminal C can access.
3. The user edits the short message through the menu or the selectable board of the user terminal B, and the user terminal B sends the priority frame and the edited short message to the user terminal C through another idle time slot.
4. The user terminal C stops receiving the call and starts receiving the high priority short message from the user terminal B.
It should be noted that, in the embodiment of the present invention, the user terminal C needs to monitor two timeslots simultaneously, and if the voice call is received in timeslot 1 and then it is monitored that timeslot 2 is the high priority service, the call in timeslot 1 is ended and the high priority service in timeslot 2 starts to be received.
User terminal a continues to send speech until the user of user terminal a releases the PTT.
It should be noted that the aforementioned user terminal may be a handheld terminal device, and may also be other communication devices such as a vehicle-mounted station.
Correspondingly, an embodiment of the present invention further provides a high-priority service sending device in the direct mode, and as shown in fig. 7, the high-priority service sending device is a schematic structural diagram of the device.
In this embodiment, the transmitting apparatus 700 includes:
an instruction unit 701, configured to receive an instruction that a user sends a high-priority service;
a frame generating unit 702, configured to generate a priority frame and a high-priority service frame according to the instruction, where the priority frame is used to enable a receiving party to identify the high-priority service according to the priority frame;
a sending unit 703, configured to send the priority frame and the high priority service frame.
It should be noted that, when transmitting the priority frame and the high priority traffic frame, the transmitting device may be in a voice call receiving state or an idle state.
To this end, in another embodiment of the present invention, as shown in fig. 8, the transmitting apparatus 800 may further include:
a receiving unit 704 for receiving a voice call;
a control unit 705, configured to detect whether the sending device is in a voice call receiving state, and if so, control the receiving unit 704 to stop receiving the voice call, and notify the sending unit 703 to send the priority frame and the high-priority service frame in another idle time slot other than the receiving time slot.
Of course, if the control unit 705 detects that the transmitting device is in the idle state, the transmitting unit 703 may be notified to optionally transmit the priority frame and the high priority traffic frame in one timeslot, for example, by default.
The high-priority service in the embodiment of the invention refers to a relatively urgent text message (such as a short message, a multimedia message) or a voice call and other services, and the sending equipment can have different deformation structures aiming at different high-priority services and application environments.
Fig. 9 is a schematic structural diagram of a high-priority traffic sending device in the direct mode according to another embodiment of the present invention.
Unlike the embodiment shown in fig. 8, in this embodiment, the transmitting apparatus 900 further includes:
a display unit 706, configured to display a prompt message indicating that the sending is successful after the receiving unit 704 receives the response frame in the idle timeslot within a preset time after the sending unit 703 finishes sending the high-priority service frame.
The sending device of this embodiment can receive a response frame returned by the other party after the sending of the high-priority service frame is finished, and display the prompt information of successful sending for the high-priority service that needs to be confirmed by the receiving party.
In addition, if the high priority service is a short message service, the display unit 706 may further display a prompt message indicating that the transmission is successful after the transmission unit 703 finishes transmitting the high priority service frame.
In practical application, in order to enable the sending device to identify whether a service sent by a user is a normal service or a high-priority service, the high-priority service sending device in the pass-through mode can be selected by the user through a menu editing mode or a selectable panel control mode, the sending device determines whether the service needing to be sent is the high-priority service according to the selection of the user, if the service is the high-priority service, the sending device generates and sends the priority frame, otherwise, the sending device does not need to generate and send the priority frame. And, before the user terminal sends the high priority service, it can inquire the channel first, if there is voice call on the channel, then send the said high priority service in another idle time slot. Of course, if there is no voice call on the channel, i.e., both slots are idle, the first slot is used by default to transmit the high priority traffic.
Therefore, in the high-priority service sending device in the direct mode according to the embodiment of the present invention, in order to enable the high-priority service receiver to identify the high-priority service, before sending the high-priority service frame, the high-priority frame is sent first, so that the receiver can correctly detect the high-priority frame, and thus preferentially receive the high-priority service.
Accordingly, an embodiment of the present invention further provides a high-priority service receiving device in a direct mode, and as shown in fig. 10, the embodiment of the present invention is a schematic structural diagram of the high-priority service receiving device in the direct mode.
In this embodiment, the reception apparatus 100 includes:
a transmitting unit 101 for transmitting a voice call;
a receiving and detecting unit 102, configured to receive a detection priority frame in another time slot corresponding to the time slot occupied by the voice call after the transmitting unit 901 transmits one voice frame;
a control unit 103, configured to notify the sending unit 101 to stop the voice call and notify the receiving unit to receive a high-priority service frame in the another timeslot after the receiving detection unit 102 detects the priority frame;
a receiving unit 104, configured to receive the high priority traffic frame in the another timeslot.
It should be noted that the voice frame currently sent by the sending unit 101 may be a normal service frame or a high priority service frame, and if the voice frame is a high priority service frame, the receiving and detecting unit 102 is further configured to detect whether the level of the high priority service indicated by the service level indication information in the priority frame is higher than the level of the voice call after the priority frame is detected. Accordingly, the control unit 103 is specifically configured to, after the reception detection unit 102 detects that the level of the high-priority service indicated by the service level indication information is higher than the level of the voice call, notify the sending unit 101 to stop the voice call, and notify the receiving unit 104 to receive a high-priority service frame in the other timeslot.
The high-priority service in the embodiment of the invention refers to services such as relatively urgent text messages or voice calls, and the receiving equipment can have different deformation structures aiming at different high-priority services and application environments.
Fig. 11 is a schematic structural diagram of a high-priority service receiving device in the pass-through mode according to another embodiment of the present invention.
Unlike the embodiment shown in fig. 10, in this embodiment, the receiving apparatus 111 further includes:
and a display unit 105, configured to display a prompt message indicating that the high-priority service is ended after the receiving unit 104 completes receiving the high-priority service frame.
In addition, if the high priority service is a short message service, the display unit 105 may further display the received short message after the receiving unit 104 completes receiving the high priority service frame.
It should be noted that, for the high-priority traffic requiring confirmation from the receiving side, after the receiving unit 104 finishes receiving the high-priority traffic frame, the transmitting unit 101 may return a response frame to the transmitting side, where the response frame needs to be transmitted in the same time slot as the time slot in which the high-priority traffic frame is received, i.e., another time slot mentioned above.
In practical applications, in order to meet application requirements of users in different environments, the high-priority service receiving device in the direct mode may enable the high-priority service function in a configuration manner, and if a user needs to be able to preferentially receive a high-priority service in a voice sending state, the function is started.
It can be seen that, in the embodiment of the present invention, the high priority service receiving device in the direct mode monitors another non-transmission timeslot for the user terminal in the voice call transmission state, and stops the voice call and receives the high priority service in the corresponding timeslot once the priority frame is detected in another timeslot, so that the user terminal accesses the high priority service preferentially.
As can be seen from the above description of the embodiments, the method and apparatus of the embodiments of the present invention make full use of two time slots in the TDMA scheme, so that not only the user terminal in the receiving state can receive the high priority service as the same as receiving the normal service, but also the user terminal in the transmitting state can preferentially receive the high priority service in another time slot.
The same and similar parts among the various embodiments in the present specification are referred to each other, and each embodiment focuses on differences from other embodiments. In particular, for the apparatus embodiment, since it is substantially similar to the method embodiment, it is relatively simple to describe, and reference may be made to some descriptions of the method embodiment for relevant points.
