Detailed Description

In order that those skilled in the art will better understand the present invention, a technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in which it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.

It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented 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.

Example 1

Fig. 1 is a flowchart of a group communication method provided in an embodiment of the present invention, where the method may be applicable to a case where a base station radio frequency sub-board communicates with a plurality of terminals in a terminal group in batches, and the method may be performed by a group communication device, where the group communication device may be implemented in a form of hardware and/or software, and the device may be configured in at least one base station radio frequency sub-board, as shown in fig. 1, and the method includes:

S110, transmitting a synchronous frame to the terminal group in the communication period.

The synchronization frame includes indication information indicating whether the communication period is a wake-up packet transmission period, the terminal group includes a plurality of terminals, and the plurality of terminals are grouped in a multi-level organization manner.

The communication period may be understood as a repetition period of the base station radio frequency sub-board transmitting the communication frame, which may be preset according to the actual situation, for example, 1s, 2s, or 5 s. The synchronization frame includes synchronization information for implementing frame synchronization of the terminal group, and indication information indicating whether the communication period is a wake-up packet transmission period. Specifically, the wake-up packet transmission period may be understood as a communication period in which the base station radio frequency sub-board transmits wake-up packet information. If the synchronous frame indicates that the communication period in which the synchronous frame is located is a wake-up packet sending period, the base station radio frequency sub-board sends corresponding wake-up packet information in the communication period, and at the moment, each terminal in the terminal group needs to monitor the information correspondingly to determine whether the terminal needs to be awakened in the communication period. If the synchronous frame indicates that the communication period in which the synchronous frame is positioned is not a wake-up packet sending period, the base station radio frequency sub-board does not send wake-up packet information in the communication period, and at the moment, each terminal in the terminal group can continue to sleep until the beginning of the next listening frame period.

Generally, one listening frame period is larger than one communication period and is an integer multiple of the communication period. For example, assuming that the communication period is 1s, the listening frame period may be 16s, and when one terminal does not detect the indication information of the wake-up packet transmission period in the synchronization frame of one communication period, the terminal may select to sleep for 16s and then receive the synchronization frame of a new communication period.

Further, the group communication method in the embodiment of the invention is mainly applicable to batch communication between the base station and the terminal group. Specifically, the terminal group includes a plurality of terminals, and the plurality of terminals are grouped in a multi-level organization manner. In a specific example, each terminal in the terminal group may be a low power device such as an electronic price tag.

Taking two-level organization as an example, under the organization architecture, a terminal group comprises a plurality of large groups, each large group comprises a plurality of small groups, and each small group comprises a plurality of terminals. Of course, it is understood that the terminal group may be further organized in three levels, four levels, or the like, and the specific organization form may be determined by the total number of terminals included in the terminal group, which is not limited in this embodiment.

S120, in the wake-up packet sending period, a wake-up terminal multi-stage description field and a data load field are sent to the terminal group.

In this embodiment, if one communication period is a wake-up packet transmission period, the base station radio frequency sub-board is required to transmit wake-up packet information, that is, a wake-up terminal multi-level description field and a data load field, to the terminal group at the same time in the communication period.

The wake-up terminal multi-level description field is used to indicate which terminals in the terminal group need to be woken up (hereinafter, collectively referred to as wake-up terminals) in the wake-up packet transmission period. The meaning of the multi-level description field can be understood as prompting each wake-up terminal in a multi-level prompting mode, for example, if the terminal group is in a two-level organization mode, the group where the wake-up terminal is located can be prompted first, then the group where the wake-up terminal is located and the specific wake-up terminals in the group are prompted, and by the prompting mode, the terminal which does not need to be awakened can determine the state of the terminal as soon as possible, and then can enter the sleep state as soon as possible, so that the power consumption is reduced to the greatest extent, and the awakening efficiency is improved.

The data load field contains data packets which need to be sent to each wake-up terminal in the current wake-up packet sending period, and each data packet contains the wake-up terminal pointed by the data packet. It can be understood that, when a terminal determines that the local terminal needs to be awakened in the current wake-up packet transmission period according to the wake-up terminal multi-level description field, it can continue to monitor each data packet in the data load field transmitted in the current wake-up packet transmission period, and extract the data packet pointing to the local terminal in the data load field.

Specifically, the operation of sending the synchronization frame to the terminal group in S110 and the operation of sending the wake-up terminal multi-level description field and the data load field to the terminal group in S120 may be performed by only a single base station radio frequency sub-board, or may be performed by multiple base station radio frequency sub-boards in cooperation in order to improve the base station data sending efficiency.

Correspondingly, when the method is performed by the cooperation of the plurality of base station radio frequency sub-boards, the sending the synchronization frame to the terminal group in the communication period may include:

transmitting a synchronization frame to the terminal group in a communication period through the first base station radio frequency sub-board;

And transmitting the wake-up terminal multi-level description field and the data load field to the terminal group in the wake-up packet transmission period, which may include:

And transmitting the wake-up terminal multistage description field and the data load field to the terminal group in the wake-up packet transmission period through the second class base station radio frequency sub-board.

In this optional embodiment, the base station radio frequency sub-boards included in the base station may be divided into two types, that is, a first type base station radio frequency sub-board and a second type base station radio frequency sub-board. The structures of the two types of base station radio frequency sub-boards can be completely consistent, and the content of the communication frames sent to the terminal group is different only in each communication period. The number of the radio frequency sub-boards of the first type base station is usually 1, the number of the radio frequency sub-boards of the second type base station can be one or more, the specific number of the radio frequency sub-boards of the second type base station can be set in a customized mode according to actual group scenes, and the embodiment is not limited to the specific number.

Correspondingly, in the communication period in S110, the timing of sending the communication frame by the first type base station radio frequency sub-board and the second type base station radio frequency sub-board, and the content of the communication frame are different.

Specifically, the first type of base station radio frequency sub-board transmits a synchronization frame to the terminal group in each communication period, where a transmission time interval of the synchronization frame is located in the front part of the communication period where the synchronization frame is located, for example, in the first 5ms or the first 1 ms. In the time interval when the first type base station radio frequency sub-board transmits the synchronization frame, the second type base station radio frequency sub-board can be in an idle state and does not transmit any data.

Further, since the first type base station radio frequency sub-board only transmits the synchronization frame, and generally transmits the synchronization frame within a short period of time within a communication period, the first type base station radio frequency sub-board can receive the heartbeat packet and the uplink data transmitted by the terminal group within the remaining time within the communication period.

Further, taking the terminal group as the secondary organization form as an example, in an optional implementation manner of this embodiment, the wake-up terminal multi-level description field includes: wake-up group description field wake-up terminal description field within wake-up group.

The wake-up big group description field may be used to indicate which big groups of the terminal groups have terminals that need to be woken up (i.e., wake-up big groups) in the wake-up packet transmission period. Further, terminals not belonging to the wake-up group can enter the sleep state as early as possible. Specifically, the wake-up group description field may include a group number set of the wake-up group, where the group number set may be in bitmap form.

The wake-up terminal description field in the wake-up group may be used to indicate which terminals in which subgroups in the wake-up group need to be woken up during the wake-up packet transmission period. Specifically, the wake-up terminal description field in the wake-up group may specifically include a group number set of the wake-up group, and a terminal identifier set (for example, may be an intra-group identifier bit) of each wake-up terminal in each wake-up group, where the group number set and the terminal identifier set may also be in a bitmap form. Or the wake-up terminal description field in the wake-up group may directly include the identification result of whether each terminal in each group in each big group is a wake-up terminal or not, and the embodiment does not limit the data form of the wake-up terminal description field in the group.

Based on the above embodiments, the inventors further consider that, although the wake-up terminal a needs to wake up in one communication period, the data packet corresponding to the wake-up terminal a in the data load field occurs at a very later time position in the communication period, and at this time, the wake-up terminal a needs to wait for a long time after waking up, which causes a certain power consumption loss. In particular, such power consumption losses are particularly pronounced when the terminals in the terminal group are very large in size. Based on this, the inventors creatively propose to divide the entire communication period further into a plurality of communication period sections, and one data load field is correspondingly transmitted in one communication period section. Through the arrangement, one wake-up terminal does not need to be fully awakened in the whole communication period, but only needs to be awakened in the communication period interval of the required received data packet, so that the wake-up power consumption is further reduced.

Accordingly, in another optional implementation manner of this embodiment, the wake-up terminal description field in the wake-up group may specifically include:

A description field of wake-up terminals in a complete wake-up group corresponding to a complete communication period, and a description field of wake-up terminals in a wake-up group corresponding to each of a plurality of communication period intervals;

The number of the data load fields is matched with the number of the communication period intervals, and each communication period interval comprises an inter-interval wake-up terminal description field and a data load field in an inter-interval wake-up group.

In this alternative embodiment, the wake-up terminal description field in the full wake-up group is used to describe which terminals in a specific group need to be woken up during the full communication period. Wake-up terminal description field in wake-up groups is used for describing which terminals in which groups need to be awakened in a communication period, so as to extract corresponding data packets in data load fields in the communication period.

In this embodiment, the number of communication period intervals included in one communication period may be preset according to the time length of the communication period and the number of data packets to be transmitted in one communication period, for example, may be 2, 3 or 4, etc., which is not limited in this embodiment, and meanwhile, the time span of each communication period interval may be the same or different and may be preset according to a specific communication scenario.

By way of example, and not limitation, a method for executing embodiments of the present invention by combining a plurality of base station radio frequency sub-boards is shown in fig. 2, where a schematic diagram of a communication frame structure of each type of base station radio frequency sub-board in a communication period is applicable to embodiments of the present invention. As shown in fig. 2, assuming that each communication period is 1s and the duration of the synchronization frame is 10ms, after the first 10ms of each second of transmission of the synchronization frame is completed by the radio frequency sub-board of the first type base station, the heartbeat packet and various uplink data sent by the terminal cluster are continuously received in the remaining 990 ms. Meanwhile, the second class base station radio frequency sub-board can be in an idle state in the first 10ms of each second, and the wake-up terminal multi-level description field and the data load field can be sent in the following 990 ms.

In the example of fig. 2, the communication cycle is divided into 2 communication cycle sections, that is, a first half communication cycle and a second half communication cycle, and further, the first half communication cycle data load field and the second half communication cycle data load field need to be transmitted in the communication cycle, respectively. Specifically, after the second type base station radio frequency daughter board ends in the idle state, firstly, a large group wake-up field (i.e., wake-up large group description field) with a duration of 5ms is sent, then a small group wake-up field (i.e., complete wake-up small group wake-up terminal description field) in a communication period with a duration of 25ms is sent, then a small group wake-up field (i.e., inter-wake-up small group wake-up terminal description field) in a first half communication period with a duration of 25ms is sent, and then, a data load field in the first half communication period with a duration of 455ms is sent continuously for each terminal wake-up in the first half communication period to receive the data packet; then, a group wakeup field in the latter half communication period of 25ms and a data load field in the latter half communication period of 455ms are continuously transmitted for each terminal that wakes up in the latter half communication period to receive the data packet.

According to the technical scheme, the base station radio frequency sub-board can respectively send the synchronous frame, the multi-stage description field of the awakened terminal and the data load field to the terminal group in a communication period marked as the awakening packet sending period, so that each terminal in the terminal group can receive the data packet pointing to the local terminal in the data load field when the local terminal is identified to be the awakening terminal in the communication period in a grading manner according to the multi-stage description field of the awakened terminal.

In an optional implementation manner of this embodiment, the wake-up terminal description field and the data load field in the wake-up group corresponding to the same communication period interval are sent by the same base station radio frequency sub-board; and

And the wake-up terminal description field and the data load field in the wake-up groups respectively corresponding to different communication period intervals are transmitted by different base station radio frequency sub-boards.

Specifically, in the example shown in fig. 2, the group wake-up field in the first half communication period and the data load field in the first half communication period adjacent to the wake-up field need to be sent out by the same base station radio frequency sub-board.

Further, it is assumed that the group wake-up field in the first half communication period and the data load field in the first half communication period adjacent thereto constitute field group 1, and the group wake-up field in the second half communication period and the data load field in the second half communication period adjacent thereto constitute field group 2. Furthermore, the field set 1 and the field set 2 may be sent by the same second type base station radio frequency sub-board, or the field set 1 and the field set 2 may be sent by two different second type base station radio frequency sub-boards.

For example, the field set 1 may be sent out by the second type base station radio frequency sub-board 1, and the field set 2 may be sent out by the second type base station radio frequency sub-board 2, which has the following advantages: the efficiency of the radio frequency sub-boards of the second class base stations can be fully exerted, and the data transmission efficiency is ensured.

In another optional implementation manner of this embodiment, all wake-up terminal multi-level description fields and data load fields in each communication period may be formed by the same second class base station radio frequency sub-board; the wake-up terminal multi-level description field and the data load field in the adjacent communication period can be sent out by different second-class base station radio frequency sub-boards so as to achieve the technical effect of fully playing the efficacy of each second-class base station radio frequency sub-board. Taking 1s corresponding to a communication period as an example, the wake-up terminal multi-level description field and the data load field included in 1s are sent out by the second type base station radio frequency sub-board 1, the wake-up terminal multi-level description field and the data load field included in 2s are sent out by the second type base station radio frequency sub-board 2, and so on.

It should be noted that, in the embodiments of the present invention, the specific content of the multi-level description field of the wake-up terminal is limited mainly by taking the terminal group as the secondary organization form as an example, and in fact, when the terminal group is in the three-level organization form or the four-level organization form, the specific form of the multi-level description field of the wake-up terminal can be obtained through simple deduction.

Specifically, when the terminal group is a three-level organization, the wake-up terminal multi-level description field may correspondingly include: wake-up group description field, wake-up terminal description field in primary wake-up group, and wake-up terminal description field in secondary wake-up group.

The wake-up group description field may be used to indicate which groups of the terminal groups have terminals to be woken up in the wake-up packet transmission period, the wake-up terminal description field in the primary wake-up group may be used to indicate which groups of the primary groups have terminals to be woken up in the wake-up packet transmission period, and the wake-up terminal description field in the secondary wake-up group may be used to indicate which groups of the primary groups have terminals to be woken up in the wake-up packet transmission period.

Similarly, when the terminal group is a four-level organization, the wake-up terminal multi-level description field may correspondingly include: the wake-up group description field, the wake-up terminal description field in the primary wake-up group, the wake-up terminal description field in the secondary wake-up group, and the wake-up terminal description field in the tertiary wake-up group are not described in detail herein.

Example two

Fig. 3 is a flowchart of a group communication method according to a second embodiment of the present invention, where the present embodiment is applicable to a case where a base station radio frequency sub-board communicates with a plurality of terminals in a terminal group in batches, and the method may be performed by a group communication device, where the group communication device may be implemented in a form of hardware and/or software, and the device may be configured in each terminal in the terminal group. Wherein, a plurality of terminals are grouped in a terminal group by means of multi-level organization. As shown in fig. 3, the method includes:

s310, receiving a synchronous frame sent by the base station radio frequency sub-board in a communication period.

Specifically, in each communication period, the terminal receives a synchronization frame sent by the base station radio frequency sub-board. The synchronization frame includes indication information indicating whether the communication period is a wake-up packet transmission period, and then, after each terminal in the terminal group receives the synchronization frame, it needs to identify whether the communication period of the current transmission synchronization frame is the wake-up packet transmission period according to the indication information.

If the communication period is a wake-up packet sending period, the terminal needs to continuously receive wake-up packet information sent by the base station radio frequency sub-board in the communication period; if the communication period is not the wake-up packet transmission period, the terminal does not need to receive any data in the current communication period, and can further continue to sleep until the next listening frame period starts.

S320, when the communication period is identified as a wake-up packet sending period according to the synchronous frame, continuously receiving a wake-up terminal multistage description field sent by the base station radio frequency sub-board in the communication period.

As described above, the wake-up terminal multi-level description field may be understood as a field indicating which terminals in the terminal group need to be woken up in the wake-up packet transmission period by means of multi-level prompting. Through the multi-level prompting mode, the terminal can determine that the local terminal directly enters the dormant state without being awakened in the current communication period until entering the next communication period in the prompting of a certain level, or the terminal can determine that the local terminal needs to be awakened in the current communication period after the multi-level prompting, and then needs to be awakened and receive corresponding data packets at a specific time point.

S330, when the local terminal is determined to be the wake-up terminal in the communication period according to the wake-up terminal multi-level description field, continuously receiving the data load field sent by the base station radio frequency sub-board in the communication period, and extracting the data packet pointing to the local terminal from the data load field.

Further, when the terminal determines that the local terminal is a wake-up terminal in the communication period, it is necessary to monitor a data load field sent by the base station radio frequency sub-board in the communication period continuously, and extract a data packet pointing to the local terminal from the data load field.

According to the technology of the embodiment of the invention, each terminal in the terminal group receives the data packet pointing to the local terminal in the data load field only when the local terminal is recognized as the wake-up terminal in the communication period in a grading manner according to the wake-up terminal multilevel description field sent by the base station radio frequency sub-board, and the multilevel wake-up mode greatly reduces the power consumption during wake-up, improves the wake-up efficiency, and enables each terminal to enter a dormant state in time after communication is completed.

On the basis of the above embodiments, when the wake-up terminal multi-level description field includes: when the description field of the wake-up group and the description field of the wake-up terminal in the wake-up group determine that the local terminal is the wake-up terminal in the communication period according to the multi-stage description field of the wake-up terminal, the method for continuously receiving the data load field sent by the radio frequency sub-board of the base station in the communication period may specifically include:

When a wake-up big group description field in the wake-up terminal multi-level description field is received, if the wake-up big group description field contains a big group identifier of a local terminal, continuing to receive wake-up terminal description fields in a wake-up small group in the wake-up terminal multi-level description field;

If the wake-up terminal field in the wake-up group contains the group identifier of the local terminal and the group identifier of the local terminal contains the local terminal identifier, continuing to receive the data load field sent by the base station radio frequency sub-board in the communication period.

In this optional embodiment, taking the terminal group as the secondary organization form as an example, the base station radio frequency sub-board can prompt the group where the wake-up terminal is located by firstly waking up the description field of the group, and then prompt the group where the wake-up terminal is located and the specific wake-up terminal in the group by prompting the description field of the wake-up terminal in the wake-up group.

Example III

Fig. 4 is a flowchart of another group communication method according to the third embodiment of the present invention. The embodiment is refined based on the foregoing embodiments, and in this embodiment, specifically, the wake-up terminal description field in the wake-up group includes: and detailing the awakening process of the terminal in the communication period when the awakening terminal description field in the complete awakening group corresponding to the complete communication period and the awakening terminal description field in the interval awakening group corresponding to the intervals of the plurality of communication periods respectively.

Accordingly, as shown in fig. 4, the method specifically may include:

s410, receiving a synchronous frame sent by the base station radio frequency sub-board in a communication period.

S420, when the communication period is identified as a wake-up packet sending period according to the synchronous frame, continuously receiving a wake-up terminal multistage description field sent by the base station radio frequency sub-board in the communication period.

S430, when the wake-up big group description field in the wake-up terminal multi-level description field is received, if the wake-up big group description field contains the big group identifier of the local terminal, continuing to receive the wake-up terminal description field in the complete wake-up small group in the wake-up terminal multi-level description field.

In this embodiment, if it is determined that the wake-up group description field does not include the group identifier to which the local terminal belongs, it is determined that the local terminal does not need to be woken up in the current communication period, and further, the local terminal may select to sleep to start the next communication period.

S440, if the wake-up terminal field in the complete wake-up group contains the group identifier of the local terminal, and the group identifier of the local terminal contains the local terminal identifier, continuing to receive the wake-up terminal description field in the inter-wake-up group corresponding to each communication cycle interval in the wake-up terminal multi-stage description field.

In this embodiment, if it is determined that the group identifier to which the local terminal belongs is not included in the wake-up terminal field in the complete wake-up group, or the group identifier to which the local terminal belongs does not include the local terminal identifier, it is determined that the local terminal does not need to be woken up in the current communication period, and further, the local terminal may select to sleep to start in the next communication period.

S450, if the local terminal is determined to be the wake-up terminal in the current communication period interval according to the wake-up terminal description field in the interval wake-up group corresponding to the current communication period interval, continuing to receive the data load field corresponding to the current communication period interval, and extracting the data packet pointing to the local terminal from the data load field.

If the local terminal is determined to be the awakening terminal in the communication period, detecting whether the local terminal is the awakening terminal in the communication period once when the description field of the awakening terminal in the interval awakening group in each communication period interval contained in the communication period arrives, and if so, continuously receiving the data load field corresponding to the current communication period interval; if not, continuing to detect whether the local terminal is the wake-up terminal in the communication period interval when the wake-up terminal description field in the interval wake-up group of the next communication period interval arrives, until the wake-up terminal description field in the interval wake-up group corresponding to the last communication period interval is detected.

If the local terminal determines that it does not belong to a wake-up terminal within the last communication period interval, the sleep may be selected to start the next listening frame period.

In this embodiment, after the local terminal extracts the data packet directed to the local terminal from the data payload field, a corresponding processing action may be performed according to the specific type of the data packet. For example, if the data packet is a query data packet, the response information (ACK, acknowledge character) matched with the query data packet needs to be transmitted point-to-point to the base station radio frequency sub-board; if the data packet is a sleep packet, the method can directly select to sleep to start the next communication period when the current wake-up interval is the last communication period interval, or select to sleep to arrive in the wake-up terminal description field in the wake-up group of the interval in the next communication period interval when the current wake-up interval is not the last communication period interval.

For more visual description of the technical solutions of the embodiments of the present invention, fig. 5 shows a schematic diagram of different execution actions of a terminal at different time phases in a communication cycle, where the embodiments of the present invention are applicable. In fig. 5, mainly, a schematic diagram of a communication frame structure of each type of base station radio frequency sub-board shown in fig. 2 in a communication period is used to correspondingly describe an execution action of a terminal based on the communication frame structure.

Specifically, as shown in fig. 5, the terminal has a certain sleep time in the interval of receiving each field, and by the above arrangement, the power consumption of each terminal in the terminal group can be further saved.

The technical scheme of the embodiment of the invention communicates with each terminal in the terminal group through the base station radio frequency sub-board based on the preset communication frame structure in the communication period, can realize the one-time rapid wake-up of a plurality of terminals in the terminal group for data communication, and simultaneously, other terminals in the same terminal group without data service can keep the technical effect of low power consumption, thereby being particularly suitable for various low power consumption devices, being capable of optimizing the wake-up mode of the existing terminal group and achieving the effective balance of power consumption and communication efficiency.

Example IV

Fig. 6 is a flowchart of a group communication method provided in a fourth embodiment of the present invention, where before a base station radio frequency sub-board performs batch communication with a plurality of terminals in a terminal group, a base station main control board organizes a plurality of data packets to be sent to obtain a data load field with high efficiency. As shown in fig. 6, the method includes:

S610, acquiring a plurality of data packets to be sent to each terminal in the terminal group.

In this embodiment, the base station main control board firstly collects a plurality of data packets to be sent to each terminal in the terminal group, and then needs to package and organize the data packets so that the base station radio frequency sub-board can effectively construct and obtain data load fields to be sent in different communication periods according to the package organization result.

In this embodiment, when the base station main control board packs and organizes each data packet, the following adaptive factors are mainly considered: different air interface rates correspond to different time lengths for transmitting one data packet; the number of data packets sent to each terminal is different; each terminal receives a data packet and has different processing time; the number of terminals within each group that need to transmit data is different. Meanwhile, as shown in fig. 2, under the set time slot of the data load field, the second type base station radio frequency sub-board needs to send each data packet in a downlink manner, and also needs to receive uplink ACK fed back by the terminal, where the group wake-up field in the first half communication period and the group wake-up field in the second half communication period have preset duration length limits. Based on the above adaptive factors, the following packing organization algorithm for each data packet is proposed.

S620, grouping the data packets according to a multi-level organization mode of the terminal group, and sorting the data packets and the data packets in each data packet group according to a preset sorting mode.

In an optional implementation manner of this embodiment, grouping the data packets according to a multi-level organization manner of the terminal group, and ordering the data packets in each data packet group and each data packet in a preset ordering manner may include:

generating data packet groups corresponding to each group according to the group to which the terminal to which each data packet points belongs; grouping the data packets corresponding to the same terminal in each group into the data packet set of the same terminal; the method comprises the steps of firstly sequencing each data packet group according to the sequence from big to small of the number of the data packets, and secondly sequencing each terminal data packet group in each data packet group according to the sequence from big to small of the number of the data packets in the terminal data packet group.

In this alternative embodiment, first, the packets belonging to the same group are clustered, and in each group, the packets belonging to the same terminal are grouped into a terminal packet set. Furthermore, the following forms can be obtained: group 1{ set of packets for terminal 1, set of packets for terminal 2, … }, group 2{ set of packets for terminal 1, set of packets for terminal 2, … }.

Then, the number of data packets included in each subgroup can be counted, the first sorting is performed on each data packet, and after the first sorting is completed, the data amount (which can be understood as the data amount) of the data packet included in the data packet group with the front sorting is large. Meanwhile, the terminal data packet sets in each data packet group are subjected to second sorting according to the sequence from the large data packet number to the small data packet number, and after the second sorting is finished, the data packet data volume (also can be understood as the data volume) contained in the terminal data packet set which is ranked in front in the same data packet group is large.

S630, sequentially obtaining the data packets according to the sorting result, and filling the data packets in the same linked list with the data packets belonging to the same terminal, closely setting the data packets in the same group, and uniformly setting the filling length of the linked list as a target to fill the data packets in a plurality of linked lists respectively.

The reason why the data packets belonging to the same terminal are filled in the same linked list is to avoid that each adjacent data packet in the data load field is transmitted to the same terminal. This is done because each terminal needs a certain time to process the data packet after receiving the data packet, and if a plurality of data packets are continuously transmitted to the same terminal in a short time, transmission congestion may occur and waiting for the occurrence of transmission, which may reduce air interface efficiency to some extent and reduce communication efficiency. Furthermore, each embodiment of the present invention proposes a multi-linked list filled data packet organization form, and when the data load field is subsequently organized, the sequence of one data packet is obtained from each linked list through the base station radio frequency sub-board each time, each data packet is filled into the data load field for transmission, as long as each data packet belonging to the same terminal is filled into the same linked list, two adjacent data packets sent to the same terminal will be separated by several data packets sent to other terminals, and the specific number of data packet intervals is determined by the preset number of linked lists. The number of linked lists can be preset by a person skilled in the art according to actual scene requirements, so that efficiency maximization is achieved.

Through the arrangement, each terminal can be guaranteed to receive a new data packet for processing after finishing processing the received data packet, the time for processing the data by the terminal is utilized to the greatest extent, the communication efficiency is optimized, and a more efficient solution is provided for scenes needing frequent communication, such as an Internet of things communication scene.

Meanwhile, the reason why the data packets in the same packet are closely arranged is that the data packets directed to the same data packet (directed to each terminal in the same group) are transmitted in a concentrated time, for example, the data packets are transmitted in a communication cycle interval, and all the terminals in the group corresponding to the data packet can enter a dormant state to reduce power consumption.

In addition, the reason that the filling length of each linked list is uniformly set is that the maximum sending time of the data packet is reduced to the greatest extent, and the communication efficiency is improved.

Accordingly, in an optional implementation manner of this embodiment, each data packet is sequentially obtained according to the sorting result, and each data packet belonging to the same terminal is filled in the same linked list, each data packet in the same group is closely arranged, and filling lengths of each linked list are uniformly set as targets, so that each data packet is respectively filled in a plurality of linked lists, which may include:

In the first sequencing result, sequentially acquiring each data packet group according to a positive sequence and a reverse sequence alternately acquiring mode;

according to the second sequencing result of each data packet group, longitudinally filling each terminal data packet set in each data packet group into a plurality of linked lists in turn;

And when each terminal data packet set is filled, selecting the current shortest chain table for filling.

Through the arrangement, the aims that all data packets belonging to the same terminal are filled in the same linked list, all data packets in the same group are arranged close to each other, and filling lengths of all linked lists are uniformly arranged can be achieved.

Specifically, fig. 7 shows a schematic diagram of a link list structure and a packet sending effect of a base station master control board packet according to an embodiment of the present invention. As shown in fig. 7, in the manner of organizing multiple linked lists of the data packets, in the data load field, adjacent data packets are sent to different terminals respectively, at least several data packets are separated, the same terminal can receive new data packets again, so that the terminal can be provided with time to process each data packet, meanwhile, the data packets of multiple subgroups are ordered from big to small according to the number of packets, then the largest minimum subgroup, the next sub-subgroup, and so on are taken for linking list formation; when the linked list is inserted, all data packets of the same terminal are put into the same linked list each time; selecting a linked list with the shortest length when the linked list is put in; to ensure that the final lengths of several linked lists are close, and that the number of groups occupied by all packets acquired in each time period is not too large, and that the packets of each packet are transmitted as continuously as possible.

In addition, fig. 8 is a schematic diagram of alternate transmission of multi-terminal data packets in a data payload field, to which the embodiment of the present invention is applicable. As shown in fig. 8, by taking and sending a packet from each of the several linked lists in sequence, the purpose of sending data packets pointing to different terminals adjacently and sending data packets pointing to the same terminal at fixed time intervals of several data packets is achieved, so as to obtain optimal air interface efficiency.

According to the technical scheme provided by the embodiment of the invention, after the data packets to be transmitted are acquired through the base station main control board, the data packets belonging to the same terminal are filled in the same linked list, the data packets in the same group are closely arranged and the filling length of the linked list is uniformly arranged as targets, the data packets are respectively filled in a plurality of linked lists, so that the base station radio frequency sub-board can fill the data packets into the data load field according to the sequence of acquiring one data packet from each linked list each time, the effect that adjacent data packets in the data load field are distributed to different terminals for execution can be realized, the data processing time of the terminals is utilized to the greatest extent, the communication efficiency is optimized, and in addition, the probability of data packet collision can be effectively reduced while the communication efficiency is ensured, so that the technical scheme of the embodiment of the invention is suitable for various complex communication scenes. Meanwhile, the efficiency of the air interface is further improved through flexible chain table construction and a data packet sending mode, and the real-time and self-adaptive data packet sending mode enables the whole scheme to have applicability and expandability.
