Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and 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, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application can be applied to private network (wherein, the private network refers to a network which is dedicated to government and public safety, public utilities, rail transit, industrial and commercial communications, and the like) communication, and is based on the Digital Mobile Radio (DMR) protocol or the information transmission in the conventional mode of Police Digital Trunking (PDT) protocol. The transmitted information may include a short message or signaling.
Fig. 2 is an information interaction method provided in the embodiment of the present application, which may include the following steps:
s201, under the condition that a sending end receives an instruction of sending the same information to a plurality of destination addresses, the destination addresses are compressed in preset air interface carriers with preset frame numbers, and a target air interface carrier is obtained.
In this embodiment, the value of the preset frame number needs to be determined according to the number of the plurality of destination addresses, and the specific implementation process of the determination is the prior art and is not described herein again.
In this embodiment, the preset air interface carrier for bearing the destination address may be a CSBK type carrier, and certainly, in practice, the preset air interface carrier may also be any other type carrier, and this embodiment does not limit the specific form of the preset air interface carrier for bearing the destination address.
In practice, the structure of the CSBK type carrier is as shown in fig. 3 (a), and the meanings indicated by "0,1,2,3,4,5,6,7" in the horizontal direction, and "0,1,2,3,4,5,6,7,8,9,10,11", "LB", "PF", "CSBKO", "FID", "Data", and "CSBK CRC" in fig. 3 (a) are the corresponding meanings in the standard DMR standard document, and are not described herein again.
Wherein "CSBKO" indicates the type of the CSBK. The specific content of the "CSBKO" is determined by the function of the CSBK carrier during its use, for example, if the CSBK carrier needs to be used as a preload wave, the content of the "CSBKO" may be "0x3D".
The DATA field is reserved for users to fill, is used for carrying user DATA and is used by various manufacturers, each manufacturer has the DATA format of each manufacturer, and the DATA can be 64-bit DATA.
In this embodiment, a plurality of destination addresses are compressed into Data, and the compression takes the form of a BitMap map, the format of which is shown in fig. 3 (b). The map format can compress 39 Destination contact addresses, wherein a Destination ID BASE field represents a BASE address of the map contact, a G/I bit indicates that the map is in a calling or a group calling, and an A bit indicates whether the map is used for responding. BitMap represents the offset of the remaining 38 destination addresses.
Take the example of sending individual call ID20, individual call ID24, individual call ID36, group call ID24, and group call ID25.
This example requires two frames of CSBK carriers, with individual call ID20, individual call ID24 and individual call ID36 for each call, and DATA padding as shown in figure 3 (c) using a one frame map. G/I padding 0 indicates the map bit is called, if each call needs to be answered, A bit padding 1, ID20 are padded to a Destination ID BASE field, and each call ID24 and each call ID36 are padded to a BitMap offset field.
The group calling ID24 and the group calling ID25 are group calling, a frame of map is needed to be used, G/I bit is filled with 1 to indicate the group calling, the group calling does not need to respond, and A bit is filled with 0. Group call ID24 is populated in the Destination ID BASE field, group call ID25, with an offset of 1. Alternatively, the padding format is as shown in fig. 3 (d).
It should be noted that, in practice, the sending end determines the call type for sending information to each destination address according to the number of contacts corresponding to each of the plurality of destination addresses, where the call type includes a single call and a group call. Taking any destination address as an example, when the number of contacts corresponding to the destination address is one, the call type for sending information to the destination address is a single call, and when there are a plurality of contacts corresponding to the destination address, the call type for sending information to the destination address is a group call.
S202, the sending end sends the information according to a preset format.
In this step, the preset format may include: after sending the normal pre-carrier, and before sending the data header of the information, sending the target air interface carrier.
That is, in this step, the sending end sends the common pre-carrier in sequence, then sends the target empty carrier in sequence, sends the data header of the information, sends the data content of the information, and finally sends the data trailer of the information. The meanings of the common pre-carrier, the header of the information, the data of the information and the trailer of the information are the same as those in the prior art, and are not described herein again.
S203, the receiving end parses a plurality of destination addresses from the target air interface carrier when receiving the target air interface carrier.
In this step, taking the air interface carrier as a CSBK carrier as an example, the manner of determining whether any data frame received by the receiving end is one of the target air interface carriers may include: and further identifying whether the frame data comprises a destination address or not by judging whether the frame data is a carrier of a CSBK type or not, if so, indicating that a currently received frame is one of the target air interface carriers, and otherwise, indicating that the currently received frame is not one of the target air interface carriers. The specific implementation manner of determining whether the frame data is a CSBK carrier and whether the CSBK carrier includes a destination address is the prior art, and is not described herein again.
In this step, the receiving end parses the target air interface carrier, and parses a plurality of destination addresses. The specific implementation manner for the receiving end to analyze the target air interface carrier is the prior art, and is not described herein again.
For example, in this step, the destination address resolved by the receiving end includes: individual call ID20, individual call ID24, individual call ID36, group call ID24, and group call ID25.
And S204, the receiving end receives the information sent after the target air interface carrier under the condition that the plurality of destination addresses obtained by analysis comprise the address of the receiving end.
In this embodiment, the receiving end indicated by the plurality of destination addresses obtained by the receiving end analysis is the receiving end that needs to receive the information. In this step, the receiving end determines whether to receive information sent after the target air interface carrier by determining whether the destination address obtained by the analysis includes the address of the receiving end.
Specifically, if the information is included, it indicates that the receiving end needs to receive the information, so that the receiving end receives the information sent after the target air interface carrier. And if not, the receiving end does not need to receive the information sent after the target air interface carrier.
S205, the receiving end judges whether the received information is the information to be responded, if yes, S206 is executed, and if not, S203 is executed.
In this embodiment, after receiving the information, the receiving end may determine whether the received information is the information to be responded according to the content of the information. Wherein, the information to be responded refers to: the information of the response message needs to be replied to the transmitting end. For example, if the content of the received message is a question, the received message is a message to be answered.
In this embodiment, when the information is to-be-responded information, the receiving end does not necessarily need to reply the response information to the transmitting end. Specifically, whether the receiving end needs to reply the response message to the sending end needs to be determined according to the determination step shown in S206.
S206, the receiving end judges whether the call type indicated by the preload wave where the address of the receiving end is located is a call, if so, S207 is executed, otherwise, S203 is executed.
In this step, if the call type indicated by the preload wave where the address of the receiving end is located is a call, the receiving end needs to reply a response message to the transmitting end.
And S207, determining the number of destination addresses representing the individual calls in the target air interface carrier.
In this embodiment, if there are multiple receiving terminals that need to reply information to the sending terminal, a situation that multiple receiving terminals reply information to the sending terminal at the same time may occur, that is, a collision problem of multiple call reply ACKs may occur. Therefore, the number of destination addresses representing individual calls in the target air interface carrier is determined in this step.
Specifically, in this step, the receiving end may use the number of destination addresses representing the individual calls, which are carried by the target air interface carrier where the address of the receiving end is located, as the number of destination addresses representing the individual calls in the target air interface carrier.
For example, in this step, the destination address representing the individual call in the target air interface carrier is determined to be individual call ID20, individual call ID24, and individual call ID36.
S208, the receiving end determines the response time slice based on the determined number.
If the number of the determined receiving terminals is multiple, the receiving terminals are indicated to need to reply response information to the sending terminal, and in order to avoid the conflict problem of the multiple call reply ACKs, the response time slices determined by each receiving terminal of the call indications can be different in the step, namely for any receiving terminal of the call indications, the response time slices of the receiving terminal are different from the response time slices of the other receiving terminals of the call indications; if the determined number is one, it indicates that only one receiving end needs to reply the response message to the sending end, and the response time slice of the receiving end can be directly determined.
In an alternative embodiment, when the determined number is multiple, the manner of determining the response time slice by the receiving end in this step may include the following steps A1 to A2:
a1, determining the size sequence of the destination address representing the individual call.
Taking the destination address of each call in the target air interface carrier as the individual call ID20, the individual call ID24, and the individual call ID36 as an example, in this step, the IDs 20, 24, and 36 are sorted according to size, specifically, from large to small, or from small to large, and this embodiment does not limit the specific sorting manner.
And A2, determining the response time slices of the receiving ends according to the different response time slices of the receiving ends indicated by the different destination addresses in the sequencing and the positions of the addresses of the receiving ends in the sequencing.
In this embodiment, the response time slices of the receiving sides indicated by different destination addresses in the sequence are different, and the destination address indicating an individual call is an individual call ID20, an individual call ID24, and an individual call ID36, and it is assumed that the response time slice of the individual call ID20 is time slice 1, the response time slice of the individual call ID24 is time slice 2, and the response time slice of the individual call ID36 is time slice 3.
Preferably, in practice, the time slices corresponding to the destination addresses representing the individual calls do not intersect in time, so that it is further ensured that the time when the receiving end that represents the different destination addresses of the individual calls replies the response message to the sending end does not conflict. Specifically, as shown in fig. 4.
The above-mentioned S205 to S208 show the time slice for the receiving end to determine whether to reply the response message to the transmitting end after receiving the message, and determine that the receiving end replies the response message to the transmitting end. In this embodiment, after the sending end sends the information, it needs to determine a response time window, where the response time window is used to respond to the response information replied by the receiving end. Specifically, the procedure of the transmitting end determining the response time window may include the following S209 to S211.
S209, the sending end judges whether a first destination address exists in a plurality of destination addresses according to the content of the sending information and the number of receiving ends indicated by each destination address, if so, S210 is executed, and if not, S201 is executed.
In this step, the first destination address is a destination address for which the corresponding receiving end needs to send the response message.
In this step, if the number of the receiving ends indicated by any destination address is multiple, the call type for sending information to the destination address is group call, and the receiving ends indicated by the destination address do not need to reply response information to the sending ends. If the number of the receiving terminals indicated by any destination address is one, the call type for sending information to the destination address is a single call. Thus, it is determined whether or not the first destination address exists among the plurality of destination addresses.
And S210, determining the number of the first destination addresses.
In this step, the number of first destination addresses is determined.
S211, taking the product of the number of the first destination addresses and the preset response time as the response time window time of the sending end.
In this embodiment, the value of the preset response time may be determined according to an actual situation, and the value of the preset response time is not limited in this embodiment.
For example, if the preset response time duration is Xms and the number of the first destination addresses is Y, the response time window duration of the sending end can be calculated to be X Yms.
In this embodiment, when the sending end sends the same information to multiple destination addresses, the sending end sends the information to the multiple destination addresses once, so that sending of duplicate data is reduced, and air interface resources are saved. Under the condition that a receiving end receives a target air interface carrier, resolving a plurality of destination addresses from the target air interface carrier; and under the condition that the destination address obtained by analysis comprises the address of the receiving end, receiving the information sent after the target air interface carrier, thereby realizing that the receiving end indicated by the destination address receives the information.
In summary, in this embodiment, under the condition that the receiving end indicated by the destination address is ensured to receive the information, the air interface resource of the sending end is saved. Wherein, the saving effect of the air interface resource can reach 41.7 to 97.4 percent.
S212, the sending end receives the response information replied by the receiving end corresponding to the first destination address within the duration of the response time window.
In this embodiment of the application, the sending end may receive the response message replied by the receiving end corresponding to the first destination address within the duration of the response time window, and specifically, if the sending end detects that the receiving end corresponding to any first destination address replies the response message within the duration of the response time window, the sending end receives the response message replied by the receiving end corresponding to the first destination address.
For some reasons, a situation that the sender does not receive the reply message returned by the receiver corresponding to the first destination address within the duration of the reply time window (for example, the receiver corresponding to the first destination address does not receive the message sent by the sender) may occur, and for such a situation, the following policy is provided in the present application:
and S213, if the response information replied by the receiving terminal corresponding to the first destination address is not received within the duration of the response time window, determining the first destination address as the second destination address.
The first destination address may be one or multiple, and if the first destination address is one, if the response message returned by the receiving end corresponding to the one first destination address is not received within the duration of the response time window, the one first destination address is determined as the second destination address, and if the first destination address is multiple, for each first destination address, if the response message returned by the receiving end corresponding to the first destination address is not received within the duration of the response time window, the first destination address is taken as the second destination address. Alternatively, the second destination address may be determined at the end of the response time window.
S214, after the end time of the response time window, resending the information to the second destination address.
If the sending end does not receive the response information replied by the receiving end corresponding to the second destination address, the process of sending the information to the receiving end by the sending end is represented, or the process of replying the response information by the receiving end has errors, in this step, the sending end can resend the information to the second destination address after the ending moment of the response time window so as to ensure that the receiving end receives the information sent by the sending end. The specific schematic diagram is shown in fig. 5.
Specifically, the sending end may use the sending method in the prior art and the sending method provided in this embodiment to resend the information to the second destination address.
It should be noted that, in practice, if there are multiple second destination addresses, it indicates that the sending end needs to resend the information to the multiple destination addresses, and in this case, the sending method provided in this embodiment is adopted, so that air interface resources can be saved. If only one second destination address exists, the sending end needs to resend the information to one destination address, and under the condition, a sending mode in the prior art can be adopted, so that a preset air interface carrier does not need to be added, and the sending cost is saved.
Specifically, with the sending method provided in this embodiment, the process of sending the information to the second destination address may include: and compressing the second destination address in a preset air interface carrier with a preset frame number to obtain a retransmission target air interface carrier, and after sending the common pre-carrier and before sending the data head of the information, sending the retransmission target air interface carrier, wherein the retransmission target air interface carrier is obtained by compressing the second destination address in the preset air interface carrier.
