Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are some embodiments of the present disclosure, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.

It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The networking referred to in the present disclosure includes, but is not limited to, ad hoc networking including, but not limited to, narrowband communication ad hoc networking in a manner including, but not limited to, implementing networking in a direct mode.

A first aspect of the present disclosure provides a data service data sending method, where the method may be applied to a forwarding node device in an ad hoc network, and the forwarding node device may be any node device in the ad hoc network that can implement data forwarding; in application, the node device includes but is not limited to a walkie-talkie.

As shown in fig. 1, the method may include the steps of:

step 101, receiving target data related to data services sent by other node devices in the same network; the target data comprises a source address field, a routing path field and a data service data field related to the initial node equipment; the source address field is used for identifying the address of the node device sending the target data, and the routing path field is used for identifying the routing path from the starting node device to the target node device.

In this embodiment, the data service includes, but is not limited to, a service specified by a protocol, such as a location information service, a short message service, or a short data service. The protocols referred to include, but are not limited to, DMR (Digital Mobile Radio) protocol, PDT (Police Digital Trunking) protocol. The target data here may be short data. For example, data smaller than a certain character may be set as the target data. More specifically, the Data of the target Data is a plurality of Data types specified by the DMR protocol, such as a Defined short message including a source address field and a routing path field, an Undefined short message, a Raw short message, a status short message, short Data, a UDT (Unified Data Transport) or an IP short message. The other node device may be an originating node device, or may be a forwarding node device in the routing path.

And 102, acquiring a routing path in a routing path field in the target data.

In this embodiment, the routing path indicates a forwarding path of data related to the data service. It should be understood that the routing path may be retrieved by the originating node device from the local routing table.

In this embodiment, based on different working states of the node devices, different frame types of the frames carrying the routing path are set. For example, when the node device is in a low power consumption state or a scanning state, a control frame in the data is set to carry a routing path; when the node device is in a non-low power consumption state and a non-scanning state, a routing path carried by a data frame or a control frame in data is set, and in a specific implementation, the routing path carried by the control frame in data can be set when the node device is in the non-low power consumption state and the non-scanning state. Therefore, the forwarding node device can acquire the routing path in the routing path field in the target data based on the working state of the forwarding node device. It should be noted that the working states of the forwarding node device and other node devices are the same, so that the forwarding node device can determine the working states of other node devices by detecting the working states of itself, so as to obtain the frame where the routing path in the target data sent by other node devices is located.

In an optional embodiment, the working state of the forwarding node is obtained; determining the frame type carrying the routing path in the target data based on the working state; a routing path is obtained from the target data based on the frame type.

In this embodiment, the frame type includes a control frame or a data frame, and thus the routing path may be obtained from the control frame or the routing path may be obtained from the data frame.

In a specific application, when the transmission target DATA is a GPS short message, the control frame may be PRE _ CSBK or the like, and the DATA frame may be DATA _ HEADER, DATA _ BLOCK, or DATA _ LASTBLOCK or the like.

In an optional embodiment, determining a frame type of a frame in which the routing path field is located in the target data based on the operating state includes: when the target data is in a low power consumption state or a scanning state, determining the frame type of a frame where a routing path field is located in the target data as a control frame; and when the target data is in a non-low power consumption state and a non-scanning state, determining that the frame type of the frame where the routing path field is located in the target data is a data frame or a control frame.

And 103, when the forwarding node equipment is determined to meet the forwarding condition based on the routing path, setting the address in the source address field in the target data as the address of the forwarding node equipment to obtain the updated target data.

It should be understood that when it is determined that the forwarding node apparatus does not satisfy the forwarding condition based on the routing path, the forwarding node apparatus does not process the target data.

The forwarding node equipment updates the address in the source address field in the target data to the address of the forwarding node equipment to obtain the updated target number, and the source address field in the updated target data identifies the node equipment sending the target data as the forwarding node equipment, so that the next node equipment can judge whether the forwarding node equipment is the previous hop node equipment after receiving the target data.

In application, each node device forwards data in sequence according to a routing path, so that when the target data is determined to be from the previous hop node device of the forwarding node based on the routing path, the forwarding node device is determined to meet the forwarding condition.

In this embodiment, the following determination result is given according to different implementation forms of the routing path, to determine whether the target data is from the previous-hop node device of the forwarding node device.

In an alternative embodiment, the destination data includes a source address field, so when the address in the source address field in the destination data and the address of the forwarding node device are determined to be adjacent in the routing path, the destination data is determined to be from the previous hop node device of the forwarding node device.

It should be understood that the node device of the previous hop may be other forwarding node devices or an originating node device, and based on a difference in specific implementation of the node device of the previous hop, the present embodiment provides the following manner for determining whether an address in a source address field in the target data and an address of the forwarding node device are adjacent in the routing path.

In an optional embodiment, judging whether a forwarding order corresponding to an address in a source address field in target data exists in a routing path; if yes, when the forwarding order of the forwarding node equipment is determined to be different from the forwarding order corresponding to the address in the source address field in the target data by the minimum order forwarding interval, the address in the source address field in the target data and the address of the forwarding node equipment are determined to be adjacent in the routing path; if the address in the source address field in the target data is not the same as the address of the initial node device in the routing path, and the forwarding sequence of the forwarding node device in the routing path is the first, the address in the source address field in the target data and the address of the forwarding node device are determined to be adjacent in the routing path. It should be understood that, when only the addresses of the node devices are included in the routing path field, the forwarding order of the corresponding addresses can be indicated by customizing the positions of the addresses in the routing path field, for example, defining the first appearing address in the routing path field as a first hop node, the second appearing address as a second hop node, and so on, so that the corresponding forwarding order can be determined by judging the position of a certain address appearing in the routing path field.

In application, the minimum order forwarding interval may be set in advance manually, for example, the minimum order forwarding interval is set to be 1, which is not limited in this embodiment specifically.

And 104, transmitting the updated target data on the control channel.

In the technical scheme provided by this embodiment, target data related to a data service, which is sent by other node devices in the same group of networks, is received; acquiring a routing path in a routing path field in target data; when the forwarding node equipment is determined to meet the forwarding condition based on the routing path, setting the address in the source address field in the target data as the address of the forwarding node equipment to obtain updated target data; the updated target data is transmitted on the control channel. Because the target data carries a routing path from the starting node device to the target node device, namely a forwarding path, after receiving the target data, each node device can judge whether the data needs to be forwarded according to the routing path in the target data, the data forwarding is transmitted according to the routing path from the starting node device to the target node device without returning a response, thereby greatly reducing the delay of forwarding data services, omitting a request response process, removing unstable factors of link establishment failure caused by the fact that a certain node in a link cannot receive a forwarding request or a response, and greatly improving the success rate of link establishment.

Based on the same inventive concept, a second aspect of the embodiments of the present disclosure provides a data service data transmission method, which is applicable to an originating node device; as shown in fig. 2, the method may include the steps of:

step 201, when data related to a data service which needs to be sent to a target node device in the same group of networks is obtained, a routing path from an initial node device to the target node device is obtained from a local routing table; the data traffic related data comprises data traffic data related to the originating node device.

In application, the data service includes, but is not limited to, a service specified by a protocol, such as a location information service, a short message service, or a short data service. Protocols referred to include, but are not limited to, DMR (Digital Mobile Radio) protocol, PDT (Police Digital Trunking) protocol.

The target data here may be short data. For example, data smaller than a certain number of characters may be set as the target data. More specifically, the Data of the target Data is a plurality of Data types specified by the DMR protocol, such as a Defined short message including a source address field and a routing path field, an Undefined short message, a Raw short message, a status short message, short Data, a UDT (Unified Data Transport) or an IP short message.

In this embodiment, the routing path in the local routing table may be obtained from the networking result in the ad hoc networking stage.

In an optional embodiment, the starting node device receives a first broadcast signaling frame broadcast by other node devices in the same group of networks in a networking stage, where the broadcast signaling frame includes path information from the other node devices to the target node; adding other node equipment into the path information to form a local routing table; a second broadcast signaling frame is generated and broadcast, the second broadcast signaling frame including local routing table information. Preferably, the path information in the broadcast signaling frame is a path with the shortest hop count from the node device to the target node device, the strongest signal and the most stable state.

Step 202, filling the address of the start node device, the data related to the data service and the routing path into a source address field, a data service data field and a routing path field respectively to obtain target data; the source address field is used to identify the address of the node device that sent the target data.

In this embodiment, based on the difference in the operating state of the start node device, the frame types of the filling routing path, the service data, and the source address are different.

In an optional embodiment, the working state of the starting node device is obtained; and determining the frame type of the frame where the routing path field is located based on the working state.

Correspondingly, the routing path is filled into the routing path field, specifically: the routing path is populated in a routing path field in a frame of the corresponding frame type.

In an application, the frame type may include a control frame or a data frame, etc. In a specific embodiment, when the start node device is in a low power consumption state or a scanning state, determining that a frame type of a frame where a routing path field is located in the target data may be set as a control frame; when the target data is in a non-low power consumption state or a non-scanning state, the frame type of the frame where the routing path field is located in the target data is determined to be a data frame or a control frame. It should be noted that the working states of the start node device and the other node devices are the same, so that the other node devices can determine the working states of the other node devices by detecting their own working states, so as to obtain the frame where the routing path in the target data sent by the other node devices is located.

In this embodiment, in order to reduce signaling collision, the routing path includes the node addresses of the forwarding node devices and the forwarding order of the forwarding nodes; meanwhile, in order to enable the destination node device to explicitly send the starting node device of the data, the routing path also includes the address of the starting node device, so that when the routing path is filled into the routing path field, the address of the starting node device is filled into the address field of the starting node device, and the address of each forwarding node device is filled into the address field of the forwarding node device according to the forwarding order.

In an optional embodiment, the routing path field comprises an originating node device address field and at least one forwarding node address field; acquiring node addresses of forwarding node devices in a routing path, forwarding orders of the forwarding nodes and addresses of starting node devices; and filling the address of the starting node equipment into the address field of the starting node equipment, and filling the address of each forwarding node equipment into the address field of the forwarding node according to the forwarding sequence.

In this embodiment, in order to make the node device that receives the target data explicitly determine from which node device the target data is received, a source address field is further set in the target data, where the source address field is used to identify an address of the node device that sends the control signaling. It can be understood that the source address field in the target data is the address of the start node device, and when other node devices receive the target data, the node device sending the target data is known as the start node device through the source address field.

Step 203, sending the target data on the control channel, so that the forwarding node device updates the address in the source address field in the target data to be the address of the forwarding node device and sends the updated target data when determining that the forwarding node device satisfies the condition of forwarding the target data based on the routing path.

It should be understood that the forwarding node apparatus does not process the target data when it is determined that the forwarding node apparatus does not satisfy the condition for forwarding the target data based on the routing path.

In an example, taking the schematic diagram of data service multi-hop forwarding shown in fig. 3 as an example, referring to the positions of the node devices in fig. 3, the networking process is specifically described by taking an example that the sequence of broadcasting and broadcasting signaling frames by the networking node devices in the direct mode is a → E → F → G → H → I, where a is the master node device. The node devices A to F are networked in a direct mode, and networking is realized by sequentially sending broadcast signaling frames, wherein the broadcast signaling frames comprise routing table fields, and the routing table fields comprise source address fields, first hop to fourth hop node device address fields and destination address fields, which are specifically shown in table one.

Watch 1

A, the source address in a broadcast signaling frame sent by A is A, no address exists in the address field of the first-hop to fourth-hop node equipment, and the destination address is A;

after the E receives the broadcast signaling frame of the A, the E knows that the A is a main control node (in the scheme, the default main control node is the first node which initiates the broadcast, and information sent by all non-main control nodes is sent to the main control node by default), the E is the first hop and forms a local routing table (the destination address is A) of the E; in the broadcast signaling frame broadcasted by E, the source address is E, no address exists in the address fields of the first-hop to fourth-hop node devices, and the destination address is A;

after receiving the broadcast signaling frame sent by the E, the F knows that the first hop node device is the E and the destination address (the master control node) is the A, the F is the second hop and forms a local routing table of the F (the destination address is the A and the first hop node device is the E); in the broadcast signaling frame broadcast by the F, the source address is F, the first hop address is E, no address exists in the address field of the second hop to fourth hop node equipment, and the destination address is A; after receiving the broadcast signaling frame sent by F, G processes according to the above method to form a local routing table of G (destination address is a, first hop node device is E, second hop node device is F), and proceeding with this method, it can be known that the local routing table of I is destination address a, first hop node device is E, second hop node device is F, third hop node device is G, and fourth hop node device is H.

Therefore, E knows that the path for itself to reach A is E → A; f knows that the path from F to A is: f → E → A; g knows that the path to a is: g → F → E → A; h knows that the path for itself to reach A is: h → G → F → E → A; i knows that the path from itself to A is: i → H → G → F → E → A.

Through the above manner, after all the node devices send the broadcast signaling frames at respective broadcast time, the node devices can acquire the path from the node device to the main control node device by receiving the broadcast signaling frames sent by other node devices, thereby completing networking. It should be noted that, networking may be performed again by all the node devices after a certain time interval, so as to realize periodic updating of networking, improve the effectiveness of the local routing table in the node device, and update the local routing table of each node device in time when the position of the node device changes.

For convenience of understanding, the schematic diagram of multi-hop forwarding of data service shown in fig. 3 is taken as an example, where the data service is specifically GPS short message service, and specifically, routing information is transmitted by using a control frame PRE _ CSBK in a GPS short message frame. In fig. 3, the a/C/D/E/F/G/H/I nodes represent relative positions of a plurality of interphones at a certain time, and the positions of the a/C/D/E/F/G/H/I nodes are constantly changed along with the movement of the user. At this moment, the A/C/D/E/F/G/H/I node has successfully constructed the ad hoc network topology in a mode of broadcasting the broadcast signaling frame, namely the networking is successful, and has routing information.

In fig. 3, the starting node device sending the data service data is node I, the forwarding node devices are sequentially H/G/F/E according to the local routing table of node I, and the destination node device is node a, that is, the routing path is I → H → G → F → E → a.

The target data (PRE _ CSBK frame in the GPS short message) transmitted by node I includes the contents as shown in table two.

The Start Address is an Address of an initial node device I, the Source is an Address of a node device (i.e., the initial node device I) currently sending target data, the Jump one is an Address of a first hop node device in the routing path field, the Jump two is an Address of a second hop node device in the routing path field, the Jump three is an Address of a third hop node device in the routing path field, and the Jump four is an Address of a fourth hop node device in the routing path field.

The first hop, the second hop, the third hop, and the fourth hop are the forwarding order of each forwarding node device.

Based on the example diagram shown in fig. 3, taking the target data as a GPS short message as an example, the signaling interaction between the nodes I/H/G/F/E/a is as follows.

1. When I sends a GPS short message to A, searching a local routing table, namely, searching a node A through four-to-five hops, generating and sending a frame PRE _ CSBK, wherein the PRE _ CSBK frame comprises the content in the table II, and sequentially sending DATAHEADER + DATABLOCK;

2. after H receives PRE _ CSBK + DATAHEADER + DATABLOCK sent by I, according to the routing information of PRE _ CSBK, inquiring that the node is in the routing table and is the first hop, if the starting node is I, judging that the forwarding condition is met, re-framing PRE _ CSBK, recording the source address as H, and if the source address is not changed, obtaining updated target data (PRE _ CSBK + DATAHEADER + DATABLOCK). Transmitting PRE _ CSBK, DATAHEADER and DATABLOCK in sequence on a control channel;

3. and G, after receiving the GPS short message of H, inquiring that the node is in the routing table and is the second hop, wherein the first hop is E, namely the node and the previous node are close to each other in the routing table, if the forwarding condition is determined to be met, then D forwards the GPS short message. The source address of PRE _ CSBK is changed to D, and the others are unchanged. And the subsequent nodes F and E sequentially forward the GPS short message.

4. And A receives the GPS short message forwarded by E, judges that the previous node is the final forwarding node, and then receives the GPS short message. And solving the source Address I from the Start Address, and displaying the source Address position.

It is to be understood that, in the above specific embodiment, the control frame PRE _ CSBK is used to carry the routing path information, and in different working states, data frames such as DATAHEADER and DATABLOCK may also be used to carry the routing path information according to the setting.
