Abstract

The invention provides a reverse signaling transmission method in a private network system. The method comprises: selecting a time slot in which non-important information is embedded, to transmit reverse signaling corresponding to a service of a current time slot; and performing time slot transfer and splitting on the selected time slot, the processed time slots from left to right successively being a first transmit-receive transition protection sub time slot, a valid payload sub time slot, a second transmit-receive transition protection sub time slot, a sub time slot for transmitting reverse signaling, and a third transmit-receive transition protection sub time slot; and transmitting service data on the valid payload sub time slot, and meanwhile, transmitting the reverse signaling corresponding to the service of the current time slot on the sub time slot for transmitting reverse signaling. Thus, service data and reverse signaling of the service data are transmitted on the same time slot without occupying a time slot for transmitting another service. In this way, a service sending party can select a time slot that does not affect service data from time slots for transmitting the service data to transmit reverse signaling without affecting service transmission of the current time slot and adjacent time slots.

Description

专网***的反向信令传输方法、装置及通信设备Reverse signaling transmission method, device and communication device of private network system

技术领域Technical field

本申请涉及通信技术领域，更具体的说是涉及一种专网***的反向信令传输方法、装置及通信设备。The present application relates to the field of communications technologies, and in particular, to a reverse signaling transmission method, apparatus, and communication device for a private network system.

背景技术Background technique

专网是相对于公网而言，公网就是普通电路交换网，例如，各个运营商架设的为社会大众服务的网络。专网是指专用网络、某个***内部的网络，只为该***服务，例如，铁路***专网、公安***专网、防汛专网、军用专网等。The private network is a common circuit switching network compared to the public network. For example, a network set up by various operators to serve the public. The private network refers to the private network and the internal network of a certain system, and only serves the system, for example, the railway system private network, the public security system private network, the flood prevention private network, the military private network, and the like.

以专网中的DMR(Digital Mobile Radio，数字移动无线电)/PDT(Police Digital Trunking，警用数字集群)为例进行说明，DMR/PDT标准中的语音以超帧为单位。每个语音超帧包含六个语音帧，每个语音帧包含两个时隙。Take DMR (Digital Mobile Radio)/PDT (Police Digital Trunking) in the private network as an example. The voice in the DMR/PDT standard is in superframe. Each voice superframe contains six speech frames, each of which contains two time slots.

请参见图1，示出了现有的一种DMR/PDT***采用的时隙结构，每个时隙为30ms；每个时隙从左到右依次为：1.25ms的收发转换保护时间、11.25ms的有效载荷部分、5ms的嵌入式信息部分、11.25ms的有效载荷部分和1.25ms的收发转换保护时间。其中，有效载荷部分用于承载业务数据；中间的5ms用于承载SYNC(Synchronization，语音同步字)或嵌入式信息。请参见图2，示出了语音超帧的示意图，每个语音超帧中A帧中间5ms嵌入SYNC，B、C、D、E、F中的任意四个帧的中间5ms需要嵌入语音控制信息(Link Control，LC)，剩余一帧的中间5ms为非重要信息，非重要信息是指当该信息缺失时不会对当前正在进行的业务造成严重影响(例如，业务中断或业务出错)。Referring to FIG. 1, a slot structure adopted by a conventional DMR/PDT system is shown, each time slot is 30 ms; each time slot is from left to right: 1.25 ms transmission and reception conversion protection time, 11.25 The payload portion of ms, the embedded information portion of 5 ms, the payload portion of 11.25 ms, and the transceiving conversion protection time of 1.25 ms. The payload part is used to carry service data; the middle 5ms is used to carry SYNC (Synchronization) or embedded information. Referring to FIG. 2, a schematic diagram of a voice superframe is shown. In the middle of each voice superframe, 5 ms is embedded in the middle of the A frame, and the middle 5 ms of any four frames B, C, D, E, and F needs to be embedded with voice control information. (Link Control, LC), the middle 5ms of the remaining frame is non-essential information, and the non-important information means that when the information is missing, it will not seriously affect the current ongoing service (for example, business interruption or business error).

DMR/PDT标准支持反向(Reverse Channel，RC)信令传输，本文中的反向信令即RC信令，RC信令嵌入到时隙中间5ms的嵌入式信息部分传输，RC信令是接收端到发射端的信令，用于实现对发射端的发射控制。例如，MS(Mobile Station，移动台)与BS(Base Station，基站)之间传输语音业务，通常MS是语音业务的发射端，BS是语音业务的接收端。现有的DMR/PDT标准是通过相邻时隙传输RC信令。例如，BS使用下行时隙1传输语音业务 A，则使用与下行时隙1相邻的下行时隙2传输语音业务A的RC信令。每次下行信道转发语音业务时都会在需要发送RC信令的位置填充RC数据。The DMR/PDT standard supports reverse channel (RC) signaling. The reverse signaling in this paper is RC signaling. The RC signaling is embedded in the embedded information part of the 5ms in the middle of the time slot. The RC signaling is received. The signaling from the end to the transmitting end is used to implement the transmission control of the transmitting end. For example, a voice service is transmitted between an MS (Mobile Station) and a BS (Base Station). Usually, the MS is the transmitting end of the voice service, and the BS is the receiving end of the voice service. The existing DMR/PDT standard is to transmit RC signaling through adjacent time slots. For example, the BS transmits the voice service using the downlink time slot 1. A, the RC signaling of the voice service A is transmitted using the downlink time slot 2 adjacent to the downlink time slot 1. Each time the downlink channel forwards the voice service, the RC data is filled at the location where the RC signaling needs to be sent.

请参见图3，示出了现有的DMR/PDT标准中对齐模式下RC信令收发时序示意图，Referring to FIG. 3, a schematic diagram of timing of RC signaling transmission and reception in an aligned mode in an existing DMR/PDT standard is shown.

DMR的帧结构采用两个时隙的帧结构，两个时隙分别用“1”和“2”表示，每个时隙可以作为一个逻辑信道。例如，MS1利用上行时隙2发送业务A，BS使用下行时隙1转发语音业务A，使用下行时隙2转发语音业务B(对应MS2)。业务A为业务B传输反向信令，业务B为业务A传输反向信令即BS在下行时隙2中嵌入语音业务A的RC信令，在下行时隙1中嵌入业务B的RC信令；MS1需要在上行时隙1相邻的时隙2接收RC信令。The frame structure of the DMR adopts a frame structure of two slots, and two slots are represented by "1" and "2", respectively, and each slot can serve as a logical channel. For example, MS1 transmits service A using uplink time slot 2, the BS forwards voice service A using downlink time slot 1, and forwards voice service B (corresponding to MS2) using downlink time slot 2. Service A transmits reverse signaling for service B, and service B transmits reverse signaling for service A, that is, RC signaling for BS embedded in voice service A in downlink time slot 2, and RC message embedded with service B in downlink time slot 1. MS1 needs to receive RC signaling in slot 2 adjacent to uplink slot 1.

现有技术中，RC信令的周期是固定的，每隔360ms发送一个RC信令，这种严格的周期使得目标MS总是知道何时可以在另一个信道上获得RC信令。但是，当需要嵌入RC信令的位置与语音业务或数据同步相冲突时，会造成语音业务中断，此种场景下，BS可能将数据和语音下行传输延迟一个突发的时间来阻止同步突发和RC信令的位置发生冲突，避免对另一时隙业务造成影响，但仍然会造成另一业务延迟等问题，不可避免地对另一时隙上传输的业务造成一定影响。In the prior art, the period of RC signaling is fixed, and one RC signaling is sent every 360 ms. This strict period makes the target MS always know when RC signaling can be obtained on another channel. However, when the location where the RC signaling needs to be embedded conflicts with the voice service or data synchronization, the voice service is interrupted. In this scenario, the BS may delay the downlink transmission of data and voice for a burst of time to prevent the synchronization burst. It conflicts with the location of the RC signaling to avoid the impact on another time slot service, but still causes another service delay, etc., which inevitably affects the services transmitted on another time slot.

经由上述的技术方案可知，本发明提供的专网***中反向信令传输方法，选择中间用于嵌入非重要信息的时隙用来传输当前时隙传输的业务数据对应的RC信令。在同时隙传输反向信令，业务数据和反向信令的收发方向相反，因此，需要在传输业务数据和传输反向信令的时隙资源之间增加收发转换保护时间，这会占用其它子时隙的时隙资源，为了减少传输反向信令对业务传输的影响，需要对传输反向信令的时隙结构进行时隙转移和拆分，最终得到的时隙结构从左到右依次为：第一收发转换保护子时隙、有效载荷子时隙、第二收发转换保护子时隙、传输反向信令的子时隙和第三收发转换保护子时隙。对于业务发射方而言，在有效载荷子时隙上发射业务数据，以及，在传输RC信令的子时隙上接收RC信令；对于业务接收方而言，在有效载荷子时隙上接收业务数据，以及，在传输RC信令的子时隙上发射RC信令。从而，实现在传输目标业务的时隙内嵌入该业务数据的RC信令，不需要占用传输另一业务的时隙。这样，业务发送方就能够从传输业务数据的时隙中选择不影响当前业务数据的时隙传输RC信令，既不会影响当前时隙更不会相邻时隙的业务传输。According to the above technical solution, the reverse signaling transmission method in the private network system provided by the present invention selects a time slot for embedding non-important information to transmit RC signaling corresponding to the service data transmitted in the current time slot. In the same time slot transmission reverse signaling, the service data and reverse signaling are sent and received in the opposite direction. Therefore, it is required to increase the transmission and reception switching protection time between the transmission service data and the time slot resource for transmitting reverse signaling, which occupies the time slot resources of other sub-time slots, and in order to reduce the impact of the transmission reverse signaling on the service transmission, It is necessary to perform time slot transfer and splitting on the slot structure for transmitting reverse signaling, and the resulting slot structure is from left to right: first transceiving switch protection subslot, payload subslot, second transceiving The protection guard subslot, the subslot for transmitting reverse signaling, and the third transceiving conversion protection subslot. For the service transmitter, the traffic data is transmitted on the payload sub-timeslot, and the RC signaling is received on the sub-timeslot in which the RC signaling is transmitted; for the service receiver, the reception is on the payload sub-timeslot Traffic data, as well as transmitting RC signaling on sub-time slots transmitting RC signaling. Thereby, the RC signaling embedding the service data in the time slot of the transmission target service is implemented, and does not need to occupy the time slot for transmitting another service. In this way, the service sender can select the time slot transmission RC signaling from the time slot in which the service data is transmitted, which does not affect the current service data, and does not affect the current time slot or the service transmission of the adjacent time slot.

具体实施方式detailed description

下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。The technical solutions in the embodiments of the present application are clearly and completely described in the following with reference to the drawings in the embodiments of the present application. It is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without departing from the inventive scope are the scope of the present application.

目前，专网***的RC信令通常是在当前业务所在时隙的相邻时隙传输，即，业务A的RC信令在业务B的时隙上传输。RC信令按照固定周期(例如，360ms)发射，当需要嵌入业务A的RC信令的位置与业务B的语音控制信息或数据同步信息冲突时，会造成业务B中断。此时，基站可能延迟业务数据下行传输，避免业务A的RC信令与业务B的数据同步信息或语音控制信息冲突，但这样仍然会造成业务B延迟。为了减小当前业务的RC信令对另一时隙业务的影响，本发明实施例在传输业务A的时隙传输业务A的RC信令。At present, the RC signaling of the private network system is usually transmitted in the adjacent time slot of the time slot in which the current service is located, that is, the RC signaling of the service A is transmitted on the time slot of the service B. The RC signaling is transmitted according to a fixed period (for example, 360 ms). When the location of the RC signaling required to be embedded in the service A conflicts with the voice control information or the data synchronization information of the service B, the service B is interrupted. At this time, the base station may delay the downlink transmission of the service data, and prevent the RC signaling of the service A from colliding with the data synchronization information or the voice control information of the service B, but this still causes the service B to delay. In order to reduce the impact of the RC signaling of the current service on another time slot service, the embodiment of the present invention transmits the RC signaling of the service A in the time slot of the transmission service A.

在DMR/PDT标准中，语音业务以超帧为单位，参见图2，每六个语音帧构成一个超帧，六个语音帧中第一帧的嵌入式信息部分嵌入语音同步字，任意四帧的嵌入式信息部分嵌入语音控制信息，剩余一帧的嵌入式信息部分嵌入非重要信息。在同时隙中传输业务数据和该业务的RC信令时，为了避免传输RC信令对当前时隙业务的影响，需要选择嵌入非重要信息的时隙作为传输RC信令的时隙。In the DMR/PDT standard, the voice service is in superframe units. Referring to FIG. 2, each of the six speech frames constitutes a superframe, and the embedded information portion of the first frame of the six speech frames is embedded in the voice synchronization word, any four frames. The embedded information part is embedded in the voice control information, and the embedded information part of the remaining frame is embedded in the non- Important information. In order to avoid the impact of transmitting RC signaling on the current time slot service when transmitting the service data and the RC signaling of the service in the same slot, it is necessary to select the time slot in which the non-important information is embedded as the time slot for transmitting the RC signaling.

如果利用图1所示的原时隙结构同时传输语音业务和RC信令，在中间的嵌入式信息部分接收RC信令，在两边的有效载荷部分发射语音业务，这样，需要在有效载荷和嵌入式信息之间增加收发转换保护时间(通常是2.5ms)。每个有效载荷部分与嵌入式信息部分之间都需要增加一个收发转换保护时间，即，需要两个收发转换保护时间(5ms)。而这5ms通常占用有效载荷部分，导致传输语音业务的时隙资源减少了5ms，从而对语音业务造成严重影响。综上所述，为了避免同时隙传输语音业务和RC信令，需要对原时隙结构进行拆分和转移。下面将通过本发明的实施例来描述具体实现同时隙传输业务数据和该业务的RC信令的方法。If the original time slot structure shown in FIG. 1 is used to simultaneously transmit voice traffic and RC signaling, the embedded information portion in the middle receives RC signaling, and the voice service is transmitted on both sides of the payload portion, thus requiring payload and embedding. Increase the transceiving conversion protection time (usually 2.5ms) between the information. A transceiving conversion protection time is required between each payload part and the embedded information part, that is, two transceiving conversion protection times (5 ms) are required. The 5ms usually occupies the payload part, which reduces the time slot resources for transmitting voice services by 5ms, which has a serious impact on the voice service. In summary, in order to avoid simultaneous transmission of voice traffic and RC signaling, the original slot structure needs to be split and transferred. A method of specifically implementing simultaneous transmission of service data and RC signaling of the service will be described below by way of an embodiment of the present invention.

下面以业务发送方(即，RC信令接收方)为主，描述本发明的反向信令传输方法。本实施例中，业务发送方在发射业务数据的时隙上接收该业务数据对应的RC信令，其中，该业务数据的RC信令由接收该业务数据的通信设备发射。The reverse signaling transmission method of the present invention is described below mainly with the service sender (ie, the RC signaling receiver). In this embodiment, the service sender receives the RC signaling corresponding to the service data on the time slot in which the service data is transmitted, where the RC signaling of the service data is transmitted by the communication device that receives the service data.

例如，对于专网***中的语音业务而言，当某个具有较低优先级的用户正在占用某信道进行语音业务，而具有更高优先级的用户需要占用该信道进行语音业务时，需要强制停止低优先级用户发射语音业务，这样，具有高优先级的用户才能使用该信道。此时，需要通过RC信令来打断低优先级用户的语音业务。在此种应用场景下，RC信令的发射方通常是基站，RC信令的接收方通常是终端(即，用户侧)。For example, for a voice service in a private network system, when a user with a lower priority is occupying a channel for voice service, and a user with a higher priority needs to occupy the channel for voice service, it needs to be forced. The low priority user is stopped from transmitting the voice service, so that the user with high priority can use the channel. At this time, the voice service of the low priority user needs to be interrupted by the RC signaling. In this application scenario, the transmitter of the RC signaling is usually the base station, and the receiver of the RC signaling is usually the terminal (ie, the user side).

本实施例中，以业务发射方是通信设备为例进行说明。在本发明的其它实施例中，业务发射方可以是终端设备或基站。In this embodiment, the description is made by taking a service transmitting device as a communication device as an example. In other embodiments of the invention, the traffic transmitter may be a terminal device or a base station.

请参见图4-图5，图4示出了本发明实施例一种专网***中的反向信令传输方法的流程图；图5示出了本发明实施例提供的一种业务发射时隙结构示意图。本实施例中，以专网***中的语音业务为例进行说明，在其它实施例中，目标业务还可以是除语音业务之外的其它业务。Referring to FIG. 4 and FIG. 5, FIG. 4 is a flowchart of a reverse signaling transmission method in a private network system according to an embodiment of the present invention; FIG. 5 is a schematic diagram of a service transmission according to an embodiment of the present invention. Schematic diagram of the gap structure. In this embodiment, the voice service in the private network system is taken as an example for description. In other embodiments, The target service can also be other services than the voice service.

如图4所示，本实施例提供的专网***中RC信令传输方法可以包括：As shown in FIG. 4, the RC signaling transmission method in the private network system provided in this embodiment may include:

S110，在发送目标业务的时隙中，检测嵌入式信息为非重要信息的时隙作为接收所述目标业务的RC信令的目标时隙。S110: In a time slot in which the target service is sent, detecting a time slot in which the embedded information is non-important information is a target time slot of the RC signaling that receives the target service.

其中，所述目标时隙从左到右依次为第一收发转换保护子时隙、有效载荷子时隙、第二收发转换保护子时隙、接收子时隙和第三收发转换保护子时隙。即将原发射时隙中分为两部分的有效载荷子时隙合并为一个有效载荷子时隙，并将原发射时隙中的嵌入式信息部分作为接收子时隙来接收当前业务的RC信令。The target time slot is, from left to right, a first transceiving conversion protection sub-slot, a payload sub-slot, a second transceiving conversion protection sub-slot, a receiving sub-slot, and a third transceiving conversion protection sub-slot. . The payload sub-slots divided into two parts in the original transmission slot are combined into one payload sub-slot, and the embedded information part in the original transmission slot is used as the receiving sub-slot to receive the RC signaling of the current service. .

具体传输RC信令的时隙位置和周期可以由业务发射方通过静态配置实现，然后，根据静态配置的时隙位置和周期确定出用于接收RC信令的目标时隙。The slot position and period of the specific transmission RC signaling may be implemented by the service transmitter through static configuration, and then the target slot for receiving the RC signaling is determined according to the statically configured slot position and period.

为了避免同时隙传输RC信令对当前时隙业务造成影响，需要对原有的时隙进行转移和拆分。确定出目标时隙后，以后的语音业务传输过程中，每次到目标时隙时都需要使用拆分和转移后的时隙结构代替原来的时隙结构。In order to avoid the impact of the slot transmission RC signaling on the current time slot service, the original time slot needs to be transferred and split. After the target time slot is determined, in the subsequent voice service transmission process, the split and transferred slot structure needs to be used instead of the original slot structure each time the target time slot is reached.

其中，原有的时隙结构如图1所示，采用30ms的时隙结构，从左到右依次是：1.25ms的收发转换保护时间、11.25ms的有效载荷、5ms的嵌入式信息部分、11.25ms的有效载荷和1.25ms的收发转换保护时间。有效载荷部分用于传输业务数据；嵌入式信息部分用于填充嵌入式信息，例如，语音同步字、语音控制信息等。收发转换保护时间用于实现发送和接收状态的转换。The original time slot structure is shown in Figure 1. The 30ms slot structure is used, from left to right: 1.25ms transmission and reception conversion protection time, 11.25ms payload, 5ms embedded information part, 11.25 The payload of ms and the transmission protection time of 1.25ms. The payload portion is used to transmit service data; the embedded information portion is used to populate embedded information, such as voice synchronization words, voice control information, and the like. Transceiver switching protection time is used to implement the conversion of the transmit and receive states.

请参见图5，示出了本发明实施例一种拆分和转移后的时隙结构示意图，本实施例以30ms的时隙为例进行说明，拆分和转移后的时隙结构从左到右依次为：1.25ms的第一收发转换保护子时隙、20ms的有效载荷子时隙、2.5ms的第二收发转换保护子时隙、5ms的接收子时隙和1.25ms的第三收发转换保护子时隙。Referring to FIG. 5, it is a schematic diagram of a slot structure after splitting and transferring according to an embodiment of the present invention. This embodiment uses a 30 ms slot as an example for description. The slot structure after splitting and transferring is from left to right. The right sequence is: 1.25ms first transceiving switch protection subslot, 20ms payload subslot, 2.5ms second transceiving switch protection subslot, 5ms receive subslot and 1.25ms third transceiving Protection subslot.

有效载荷用于发射语音业务，而接收子时隙用于接收RC信令，因此，通过第二收发转换保护子时隙实现有效载荷和接收子时隙之间的收发转换过程。The payload is used to transmit voice traffic, and the receiving sub-slot is used to receive RC signaling. Therefore, the transmission and reception conversion process between the payload and the receiving sub-slot is implemented by the second transceiving switching protection sub-slot.

需要说明的是，图5所示的时隙结构仅仅是一种具体的实例，其中，第一收发转换保护子时隙和第三收发转换保护子时隙均为1.25ms固定不变，有效载荷子时隙、第二收发转换保护子时隙和接收子时隙的时间均可以根据需求进行微调，本申请对此并不限制。It should be noted that the time slot structure shown in FIG. 5 is only a specific example, in which the first transceiving switch protection sub-slot and the third transceiving switch protection sub-slot are both fixed at 1.25 ms, which is effective. The time of the load sub-time slot, the second transceiving conversion protection sub-slot, and the receiving sub-slot can be fine-tuned according to requirements, which is not limited in this application.

在本发明的其它可能的实现方式中，当第二收发转换保护子时隙为0ms且所述有效载荷子时隙为20ms时，所述接收子时隙为7.5ms；当所述第二收发转换保护子时隙为0ms且所述有效载荷子时隙为22.5ms时，所述接收子时隙为5ms；当所述第二收发转换保护子时隙为2.5ms且所述有效载荷子时隙为22.5ms时，所述接收子时隙为2.5ms。In other possible implementation manners of the present invention, when the second transceiving conversion protection sub-time slot is 0 ms and the payload sub-time slot is 20 ms, the receiving sub-time slot is 7.5 ms; when the second transceiving When the conversion protection sub-time slot is 0 ms and the payload sub-time slot is 22.5 ms, the reception sub-time slot is 5 ms; when the second transceiving conversion protection sub-time slot is 2.5 ms and the payload is sub-timed When the slot is 22.5 ms, the receiving subslot is 2.5 ms.

S120，在有效载荷子时隙上发射目标业务，以及，在接收子时隙上接收该目标业务的RC信令。S120. Transmit a target service on a payload sub-slot, and receive RC signaling of the target service on the receiving sub-slot.

在图5所示的有效载荷子时隙上发射语音业务，以及，在接收子时隙上接收该语音业务的RC信令。The voice traffic is transmitted on the payload sub-timeslot shown in FIG. 5, and the RC signaling of the voice service is received on the receiving sub-timeslot.

本实施例提供的专网***中反向信令传输方法，业务发射方选择中间用于嵌入非重要信息的时隙用来传输当前时隙传输的业务数据对应的RC信令。而且，为了不影响当前时隙的业务，对选择的时隙进行时隙转移和拆分，最终得到的时隙从左到右依次为：第一收发转换保护子时隙、有效载荷子时隙、第二收发转换保护子时隙、接收子时隙和第三收发转换保护子时隙。目标时隙是将原有时隙结构中的两个分离的有效载荷部分合并为一个有效载荷部分，依然用来传输业务数据；以及，将原来位于中间的嵌入式信息部分转移到整个有效载荷部分之后用来传输RC信令。这样，转移和拆分后的时隙结构只需要增加一个收发转换保护时间，减小传输RC信令对有效载荷部分的占用，从而大大降低了传输RC信令对业务传输的影响。然后，在转移和拆分后的时隙结构中的有效载荷子时隙上发射业务数据，以及，在接收子时隙上接收RC信令；从而，实现在同一时隙上传输业务数据和该业务数据的RC信令。这样，业务发送方就能够从传输业务数据的时隙中选择不会影响业务数据的时隙来传输RC信令，不会影响当前时隙和相邻时隙的业务传输。In the reverse signaling transmission method in the private network system provided by this embodiment, the service transmitter selects a time slot for embedding non-critical information in the middle to transmit RC signaling corresponding to the service data transmitted in the current time slot. Moreover, in order not to affect the service of the current time slot, time slot transfer and splitting are performed on the selected time slot, and the finally obtained time slots are from left to right: the first transceiving conversion protection sub-slot, the payload sub-slot And a second transceiving switching protection sub-slot, a receiving sub-slot, and a third transceiving switching protection sub-slot. The target time slot is to merge two separate payload parts in the original time slot structure into one payload part, which is still used to transmit service data; and, after transferring the embedded information part originally located in the middle to the entire payload part Used to transmit RC signaling. In this way, the slot structure after the transfer and split only needs to add one transmission and reception conversion protection time, and reduce the occupation of the payload portion by the transmission RC signaling, thereby greatly reducing the impact of the transmission RC signaling on the service transmission. Then, transmitting the service data on the payload sub-slot in the transferred and split slot structure, and receiving the RC signaling on the receiving sub-slot; thereby, transmitting the service data on the same time slot and RC signaling of service data. In this way, the service sender can select the time slot that does not affect the service data from the time slot in which the service data is transmitted to transmit the RC signaling, and does not affect the service transmission of the current time slot and the adjacent time slot.

下面将以业务接收方(即，RC信令发射方)为主，描述本发明实施例的反向信令传输方法。 The reverse signaling transmission method of the embodiment of the present invention will be described below mainly with the service receiver (ie, the RC signaling transmitter).

请参见图6-图7，图6示出了本发明实施例另一种专网***中的反向信令传输方法的流程图；图7示出了本发明实施例提供的一种改进后的业务接收时隙的结构示意图。Referring to FIG. 6 FIG. 7 , FIG. 6 is a flowchart of a reverse signaling transmission method in another private network system according to an embodiment of the present invention; FIG. 7 is a schematic diagram of an embodiment of the present invention. Schematic diagram of the service receiving time slot.

本实施例对于业务接收方(即，接收业务数据的通信设备)而言，在接收业务数据的时隙上发射该业务对应的RC信令，该RC信令发送给发射该业务的通信设备。In this embodiment, for the service receiver (ie, the communication device that receives the service data), the RC signaling corresponding to the service is transmitted on the time slot in which the service data is received, and the RC signaling is sent to the communication device that transmits the service.

如图6所示，本实施例提供的反向信令传输方法可以包括：As shown in FIG. 6, the reverse signaling transmission method provided in this embodiment may include:

S210，在接收目标业务的时隙中，确定出用于发射目标业务所对应RC信令的目标时隙。S210. Determine, in a time slot in which the target service is received, a target time slot for transmitting RC signaling corresponding to the target service.

其中，对目标时隙进行转移和拆分，最终得到的时隙结构从左到右依次为：第一收发转换保护子时隙、有效载荷子时隙、第二收发转换保护子时隙、发射子时隙和第三收发转换保护子时隙。The target time slot is transferred and split, and the resulting time slot structure is from left to right: the first transceiving conversion protection sub-slot, the payload sub-slot, the second transceiving conversion protection sub-slot, and the transmission. The subslot and the third transceiving switch protect the subslot.

在本发明一种可能的实现方式中，传输RC信令的时隙位置和周期由业务发射方(即，RC信令接收方)确定，并通知给业务接收方(即，RC信令发射方)。业务接收方根据业务发射方确定的传输RC信令的时隙位置和周期，确定出发射RC信令的目标时隙。In a possible implementation manner of the present invention, the slot position and period of transmitting the RC signaling are determined by the service transmitter (ie, the RC signaling receiver) and notified to the service receiver (ie, the RC signaling transmitter) ). The service receiver determines the target time slot for transmitting the RC signaling according to the slot position and period of the transmission RC signaling determined by the service transmitter.

在本发明另一种可能的实现方式中，如果业务发射方没有通知业务接收方传输RC信令的时隙位置和周期，则需要业务接收方检测接收到的业务时隙来确定传输RC信令的时隙位置和周期，然后，确定出发射RC信令的目标时隙。In another possible implementation manner of the present invention, if the service transmitter does not notify the service receiver to transmit the slot position and period of the RC signaling, the service receiver needs to detect the received service time slot to determine the transmission RC signaling. The slot position and period are then determined by the target slot in which the RC signaling is transmitted.

具体的检测过程如下：The specific detection process is as follows:

在接收语音业务的过程中，第一次解析到在同一时隙中的连续时隙资源上接收所述目标业务，且在所述同一时隙中的剩余时隙资源未接收到射频载波信号时，确定所述该时隙为嵌入RC信令的候选时隙；第二次解析到在同一时隙中的连续时隙资源上接收所述目标业务，且在所述同一时隙中的剩余时隙资源未接收到射频载波信号时，确定这两个时隙之间的时间差为发射RC信令的周期。然后，根据检测到的RC信令的时隙位置及周期，确定出发射RC信令的目标时隙。In the process of receiving the voice service, the first time is resolved to receive the target service on consecutive time slots resources in the same time slot, and when the remaining time slot resources in the same time slot do not receive the radio frequency carrier signal Determining that the time slot is a candidate time slot embedded in RC signaling; the second time is parsing to receive the target service on consecutive time slot resources in the same time slot, and remaining in the same time slot When the slot resource does not receive the RF carrier signal, it is determined that the time difference between the two slots is the period in which the RC signaling is transmitted. Then, based on the detected slot position and period of the RC signaling, the target slot for transmitting the RC signaling is determined.

为了避免同时隙传输RC信令对当前时隙业务造成影响，需要对原有的时隙进行转移和拆分。 In order to avoid the impact of the slot transmission RC signaling on the current time slot service, the original time slot needs to be transferred and split.

原有的时隙结构如图1所示，该时隙采用30ms的时隙结构，从左到右依次为：1.25ms的收发转换保护时间、11.25ms的有效载荷、5ms的嵌入式信息、11.25ms的有效载荷和1.25ms的收发转换保护时间。有效载荷用于接收业务数据，嵌入式信息部分用于填充语音同步字、语音控制信息等，收发转换保护时间用于实现发送与接收状态的切换。The original time slot structure is shown in Figure 1. The time slot adopts a 30ms time slot structure. From left to right: 1.25ms transmission and reception conversion protection time, 11.25ms payload, 5ms embedded information, 11.25 The payload of ms and the transmission protection time of 1.25ms. The payload is used to receive service data, and the embedded information part is used to fill the voice synchronization word, voice control information, etc., and the transmission and reception conversion protection time is used to implement the switching between the sending and receiving states.

仍以30ms时隙为例进行说明，处理后的时隙结构如图7所示，拆分后的时隙结构从左到右依次为：1.25ms的第一收发转换保护子时隙、20ms的有效载荷子时隙、2.5ms的第二收发转换保护子时隙、5ms的发射子时隙和1.25ms的第三收发转换保护子时隙。The 30ms time slot is still taken as an example for description. The processed time slot structure is as shown in FIG. 7. The split time slot structure is from left to right: 1.25ms first transmission and reception conversion protection sub-timeslot, 20ms. The payload sub-slot, the 2.5 ms second transceiving switch protection sub-slot, the 5 ms transmit sub-slot, and the 1.25 ms third transceiving switch protection sub-slot.

其中，有效载荷用于发射语音业务，而接收子时隙用于接收RC信令，因此，有效载荷和接收子时隙时间需要通过第二收发转换保护子时隙实现有效载荷和接收子时隙之间的收发转换过程。The payload is used to transmit voice services, and the receiving sub-slot is used to receive RC signaling. Therefore, the payload and the receiving sub-slot time need to implement the payload and the receiving sub-slot through the second transceiving switching protection sub-slot. The process of transceiving between conversions.

需要说明的是，图7所示的时隙结构仅仅是一种具体的实例，其中，第一收发转换保护子时隙和第三收发转换保护子时隙均为1.25ms固定不变，有效载荷子时隙、第二收发转换保护子时隙和发射子时隙的时间均可以根据需求进行微调，本申请对此并不限制。It should be noted that the time slot structure shown in FIG. 7 is only a specific example, in which the first transceiving conversion protection sub-time slot and the third transceiving conversion protection sub-time slot are both fixed at 1.25 ms, and the payload is fixed. The time of the sub-slot, the second transceiving and switching sub-slot and the sub-slot can be fine-tuned according to requirements, which is not limited in this application.

在本发明的其它可能的实现方式中，当第二收发转换保护子时隙为0ms且所述有效载荷子时隙为20ms时，所述发射子时隙为7.5ms；当所述第二收发转换保护子时隙为0ms且所述有效载荷子时隙为22.5ms时，所述发射子时隙为5ms；当所述第二收发转换保护子时隙为2.5ms且所述有效载荷子时隙为22.5ms时，所述发射子时隙为2.5ms。In other possible implementation manners of the present invention, when the second transceiving and switching protection subslot is 0 ms and the payload subslot is 20 ms, the transmitting subslot is 7.5 ms; when the second transceiving When the conversion protection sub-time slot is 0 ms and the payload sub-time slot is 22.5 ms, the transmission sub-time slot is 5 ms; when the second transceiving conversion protection sub-time slot is 2.5 ms and the payload is sub-timed When the slot is 22.5 ms, the transmit subslot is 2.5 ms.

S220，在有效载荷子时隙上接收所述目标业务，在发射子时隙上发射目标业务的RC信令。S220. Receive the target service on a payload sub-slot, and transmit RC signaling of the target service on the transmit sub-slot.

发射RC信令的通信设备在图7所示的20ms的有效载荷子时隙上接收语音业务，在5ms的发射子时隙上发射该语音业务对应的RC信令。The communication device transmitting the RC signaling receives the voice service on the 20 ms payload sub-slot shown in FIG. 7, and transmits the RC signaling corresponding to the voice service on the 5 ms transmission sub-slot.

本实施例提供的专网***中反向信令传输方法，选择中间用于嵌入非重要信息的时隙用来传输当前时隙传输的业务数据对应的RC信令，并对该时隙进行时隙转移和拆分，最终得到的时隙从左到右依次为第一收发转换保护子时隙、有效载荷子时隙、第二收发转换保护子时隙、发射子时隙和第三收发转换保护子时隙。然后，业务接收方在有效载荷子时隙上接收业务发送方发送的业务数据，并在发射子时隙上发送RC信令。从而，实现在同一时隙上传输业务数据和该业务数据的RC信令，而不是占用传输另一业务的时隙。这样，业务发射方就能够选择嵌入非重要信息的时隙接收RC信令，从而不会影响当前时隙的业务传输，更不会影响相邻时隙的业务传输。The reverse signaling transmission method in the private network system provided in this embodiment selects a time slot for embedding non-important information in the middle to transmit RC signaling corresponding to the service data transmitted in the current time slot, and performs time slots on the time slot. Gap transfer and splitting, the resulting time slots from left to right are the first transceiving switch protection sub-slot, the payload sub-slot, the second transceiving switch protection sub-slot, the transmit sub-slot and the third transceiving Protection subslot. Then, the service receiver receives the service data sent by the service sender on the payload sub-slot, and transmits the RC signaling on the transmission sub-timeslot. Thereby, the transmission of the service data and the RC signaling of the service data on the same time slot is realized instead of occupying the time slot in which another service is transmitted. In this way, the service transmitter can select the time slot in which the non-important information is embedded to receive the RC signaling, so that the service transmission of the current time slot is not affected, and the service transmission of the adjacent time slots is not affected.

请参见图8，示出了本发明实施例一种同时隙传输业务数据和RC信令的收发示意图，该示意图中包括业务发射方(即，RC接收方)和业务接收方(即，RC发射方)。Referring to FIG. 8, a schematic diagram of transmission and reception of simultaneous slot transmission service data and RC signaling according to an embodiment of the present invention is shown. The schematic diagram includes a service transmitter (ie, an RC receiver) and a service receiver (ie, an RC transmitter). square).

业务收发双方利用上述方法确定出传输RC信令的目标时隙，并对目标时隙进行拆分处理，每个语音超帧中除了携带语音同步字的A帧之外，其它的B、C、D、E、F帧中的任意一帧都可以嵌入非重要信息，并选择嵌入非重要信息的时隙作为传输RC信令的目标时隙。The service transceiver party uses the above method to determine the target time slot for transmitting the RC signaling, and splits the target time slot. In addition to the A frame carrying the voice synchronization word in each voice superframe, other B, C, Any frame in the D, E, and F frames can embed non-critical information, and select a time slot in which non-important information is embedded as a target time slot for transmitting RC signaling.

例如，收发双方约定或RC发射方检测到在C帧按照360ms周期进行时隙拆分，这样，每个语音超帧中都有一次收发RC信令的机会，可以做到收发RC信令的延迟最小。具体的通信过程如图8所示。For example, the transmitting and receiving parties agree or the RC transmitting party detects that the time slot is split according to the 360 ms period in the C frame, so that each voice superframe has an opportunity to send and receive RC signaling once, and the delay of transmitting and receiving the RC signaling can be achieved. The smallest. The specific communication process is shown in Figure 8.

业务接收方在A、B、D、E、F帧按照原时隙结构接收语音业务数据；C帧按照图7所示的时隙结构进行拆分和处理，然后，在C帧中的有效载荷部分接收语音业务数据，以及，在C帧的发射子时隙上发射RC信令。The service receiver receives the voice service data in the original slot structure in the A, B, D, E, and F frames; the C frame is split and processed according to the slot structure shown in FIG. 7, and then the payload in the C frame. Partially receiving voice traffic data, and transmitting RC signaling on the transmit sub-timeslot of the C-frame.

同理，业务发射方在A、B、D、E、F帧按照原时隙结构发送语音业务数据；C帧按照图5所示的时隙结构进行拆分和处理，然后，在C帧中的有效载荷部分发送语音业务数据，以及，在C帧的接收子时隙接收RC信令。Similarly, the service transmitter transmits voice service data in the original slot structure in the A, B, D, E, and F frames; the C frame is split and processed according to the slot structure shown in FIG. 5, and then, in the C frame. The payload portion transmits voice traffic data, and receives RC signaling in the receiving sub-slot of the C frame.

本实施例提供的反向信令传输方法，选择中间用于嵌入非重要信息的时隙用来传输当前时隙传输的业务数据对应的RC信令。同时隙传输反向信令时，业务数据和反向信令的传输方向相反，因此，需要在传输业务数据和传输反向信令的时隙资源之间增加收发转换保护时间。而新增的收发转换保护时间会占用其它子时隙的资源，为了减少传输反向信令对业务传输的影响，需要对传输反向信令的时隙机构进行转移和拆分，最终得到的时隙结构从左到右依次为第一收发转换保护子时隙、有效载荷子时隙、第二收发转换保护子时隙、传输反向信令的子时隙和第三收发转换保护子时隙。在有效载荷子时隙上接收业务数据，以及，在传输RC信令的子时隙上发射RC信令。从而，实现在传输目标业务的时隙内嵌入该业务数据的RC信令，不需要占用传输另一业务的时隙。这样，业务发送方就能够从传输业务数据的时隙中选择不影响当前业务数据的时隙传输RC信令，既不会影响当前时隙更不会相邻时隙的业务传输。In the reverse signaling transmission method provided in this embodiment, the time slot used for embedding non-important information is used to transmit the RC signaling corresponding to the service data transmitted in the current time slot. When the reverse signaling is transmitted at the same time, the transmission direction of the service data and the reverse signaling is reversed. Therefore, it is necessary to increase the transmission and reception conversion protection time between the transmission service data and the time slot resource for transmitting the reverse signaling. The newly added transceiving switching protection time will occupy the resources of other sub-slots. In order to reduce the impact of the transmission reverse signaling on the service transmission, the slot mechanism that transmits the reverse signaling needs to be transferred and split, and finally obtained. The slot structure is from left to right A transceiving conversion protection sub-slot, a payload sub-slot, a second transceiving conversion protection sub-slot, a sub-slot transmitting reverse signaling, and a third transceiving conversion protection sub-slot. The traffic data is received on the payload sub-timeslot, and the RC signaling is transmitted on the sub-timeslots in which the RC signaling is transmitted. Thereby, the RC signaling embedding the service data in the time slot of the transmission target service is implemented, and does not need to occupy the time slot for transmitting another service. In this way, the service sender can select the time slot transmission RC signaling from the time slot in which the service data is transmitted, which does not affect the current service data, and does not affect the current time slot or the service transmission of the adjacent time slot.

为了进一步减少传输RC信令所占用的时隙资源，可以将RC信令中的RC数据及指示信息分开传输，相当于将一个RC信令拆分成两个RC信令，以减少传输一个RC信令所占用的时隙资源。In order to further reduce the time slot resources used for transmitting the RC signaling, the RC data and the indication information in the RC signaling may be separately transmitted, which is equivalent to splitting one RC signaling into two RC signaling to reduce transmission of one RC. The time slot resource occupied by the signaling.

RC信令中可以包括一定比特的特殊识别图样，用于对该RC信令的识别和同步，RC的特殊识别图样的两边可以包括一定比特的RC数据，用于承载具体的控制数据，RC数据包括控制数据，CRC(Cyclic Redundancy Check，循环冗余校验码)校验和纠错码，构成完整的RC帧。The RC signaling may include a special identification pattern of a certain bit for identifying and synchronizing the RC signaling, and both sides of the special identification pattern of the RC may include a certain bit of RC data for carrying specific control data, RC data. It includes control data, CRC (Cyclic Redundancy Check) checksum and error correction code to form a complete RC frame.
