Detailed Description

The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.

The data transmission method provided by the application can be applied to an application environment shown in figure 1. Wherein the terminal 102 may communicate with the base station 104 via a network. The base station can generate a wake-up signal according to the wake-up range and the service channel identifier, and add the wake-up signal into the wake-up channel, the terminal acquires the wake-up signal in the wake-up channel, then analyzes the acquired wake-up signal to obtain the wake-up range, the terminal determines whether the current wake-up is self according to the wake-up range, if so, the terminal wakes up according to the service channel identifier in the wake-up signal, and realizes data transmission based on the service channel identifier. The terminal 102 may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, among others. The base station 104 refers to a radio transceiver station for transmitting information with a mobile phone terminal through a mobile communication switching center in a certain radio coverage area, and in the present application, the base station 104 is taken as an example, and in other embodiments, the base station may be a control end in a local area network.

In one embodiment, as shown in fig. 2, a data transmission method is provided, and the method is applied to the terminal in fig. 1 for illustration, and includes the following steps:

Step 202, a wake-up signal is received in a wake-up channel.

A wake-up channel and at least one service channel are defined in the base station, wherein the wake-up channel is a channel used by the base station for realizing wake-up signal transmission, and the service channel is used for carrying out service data transmission between the terminal and the base station.

The wake-up signal is used for realizing the function of waking up the terminal, the terminal periodically monitors the wake-up signal sent by the base station in the wake-up channel, receives the wake-up signal, and analyzes the command information according to the frame format of the wake-up signal.

When the base station needs to wake up the terminal, the base station can package relevant contents such as a wake-up range, a service channel identifier and the like into a wake-up signal according to the need, for example, the base station sets a transmission mode of the wake-up signal and the wake-up range in the wake-up signal according to a preset mode of a system protocol, parameters and data access information, and then accesses the wake-up signal into the wake-up channel so that the terminal can acquire the wake-up signal from the wake-up channel.

Further, the base station periodically accesses the wake-up signal to the wake-up channel, so that the terminal can periodically acquire the wake-up signal from the wake-up channel to report the service data. Optionally, the terminal may also automatically report the data periodically. The period of the base station sending the wake-up signal is far greater than the period of the terminal automatically reporting data, for example, the period of the base station sending may be 10s, and the period of the terminal automatically reporting data may be more than 12 hours. If the terminal receives the wake-up signal, the terminal can set the identification of the reported data, and the terminal does not report the data automatically any more, but reports the data according to the wake-up signal. If the terminal does not receive the wake-up signal, the service data is still automatically reported according to the original period.

Step 204, parse the wake-up signal to obtain a wake-up range.

Specifically, the wake-up range refers to a range of terminals that need to be woken up by the wake-up signal, and for example, the wake-up range may be a range where only one terminal is woken up, or at least two terminals are woken up. When the wake-up signal needs to wake up at least two terminals, the wake-up signal is called an area wake-up signal, and when the wake-up signal needs to wake up one terminal, the wake-up signal is called a single-terminal wake-up signal.

Wherein at least two terminals in the wake-on-area signal may be classified according to different criteria, e.g. according to geographical location or power consumption of the terminal, and in other embodiments may be manually classified by a user. Optionally, the division is performed based on the power consumption of the terminal, the low-power-consumption terminal is divided into a first category, the medium-power-consumption terminal is divided into a second category, the high-power-consumption terminal is divided into a third category, and after the classification is completed, the corresponding area identifier is set for each category.

The wake-up range may be represented by a wake-up identifier, such as a terminal identifier, a zone identifier, etc. The terminal identity is a unique identity for determining the terminal, and the region identity is a unique identity for determining the divided traffic channel region.

The terminal periodically acquires a wake-up signal from the wake-up channel, and analyzes the wake-up signal to obtain a relevant wake-up range when the wake-up signal is received.

And step 206, judging whether to perform data access according to the wake-up range, and if so, acquiring a service channel identifier.

Specifically, the service channel identifier is an identifier for uniquely determining a service channel, for example, it may be that different identifiers are allocated to each service channel, or the service channel is classified first to obtain a type identifier of service channel classification, then different serial number identifiers are allocated to the service channel in each classification, and further, the identifier of the service channel may be obtained through the service channel type identifier and the serial number identifier.

Further, determining whether the current to-be-waked terminal is according to the wake-up range may include, first, obtaining a type of the wake-up range, if a single terminal wake-up signal is used, determining whether a terminal identifier in the wake-up signal is the same as a terminal identifier of the terminal itself, if a local wake-up signal is used, determining whether a region identifier of a region to which the terminal itself belongs is the same as a region identifier in the wake-up signal.

After the terminal analyzes the wake-up range, and determines that the current wake-up request is the terminal of the terminal, the terminal obtains the service channel identifier, wherein the terminal can analyze from the wake-up signal to obtain at least one service channel identifier.

If the terminal analyzes the wake-up signal to determine that the terminal does not wake up itself, the terminal reenters the sleep, and periodically acquires the wake-up signal from the service channel.

And step 208, transmitting data to the service channel corresponding to the service channel identifier.

When the terminal determines the corresponding service channel, the terminal can directly realize the transmission of related data with the service channel.

Further, when determining the service channel, the terminal may send an access request, and after the service channel returns a request for granting access based on the access request, the terminal and the service channel implement connection, and implement data transmission based on the connection.

Furthermore, when the terminal and the service channel are accessed, the service channel can determine whether to agree with the terminal to realize the access according to the self condition, if the current service channel determines that the current service channel has heavy load according to the collected data, for example, the data transmission rate is slow, the data transmission is congested and the congestion duration is longer, the terminal returns the access refusing information according to the access request at this time so as to search other service channels to realize the data transmission, thereby improving the success rate of the data transmission and also reducing the problem of overlarge power consumption caused by the fact that the terminal is always in a data transmission state. Optionally, after receiving the response information of rejecting access of the service channel, the terminal may periodically reinitiate the access request until receiving the grant access returned by the service channel, or may also repeat sending the access request periodically, where the number of times of rejecting access returned by the received service channel is a preset number of times, for example, may be 5 times, and at this time, one service channel may be reselected from the acquired at least one service channel, and the access request is sent.

If the terminal fails to transmit data, the terminal can enter a dormant state, and the steps are repeated when the wake-up range signal is received again.

In the data transmission method, the wake-up range is obtained according to the wake-up signal by receiving the wake-up signal in the wake-up channel, whether data access is performed is further judged according to the wake-up range, when the fact that data access is required is determined, the service channel identification is acquired, data is transmitted to the service channel corresponding to the service channel identification, whether data transmission is performed or not is determined on the basis of the wake-up signal, the current required wake-up terminal can be determined in a targeted manner, then the terminal can wake up again when the wake-up is definitely required, data transmission is further achieved according to the acquired service channel, and power consumption caused by the fact that the terminal continuously transmits data is effectively reduced.

In one embodiment, as shown in fig. 3, step 206, i.e., the traffic channel identification acquisition step, may include:

in step 302, the wake-up signal is parsed to determine if the wake-up signal includes a traffic channel identification.

After the terminal acquires the wake-up signal, analyzing the wake-up signal to determine whether the current wake-up signal comprises a service channel identifier, if the current wake-up signal does not comprise the service channel identifier when the wake-up signal is formed, the acquisition of the service channel identifier fails, and at the moment, a relevant service channel can be acquired from the service channel identifiers prestored in the terminal.

Specifically, the wake-up signal includes a command code, command parameter information and a service channel type, where the command code is used to determine a wake-up range, that is, to determine whether the wake-up range is single-terminal wake-up or area wake-up, and the command parameter information is specific content of a determined wake-up range, that is, if the wake-up range is single-terminal wake-up, the command parameter information may include a terminal identifier, and if the service channel identifier corresponding to the terminal identifier is area wake-up, the command parameter may include an area identifier, and the area identifier may include a service channel sequence number, an access priority, and so on. The traffic channel type is different types of channels provided by the base station, and can be divided according to different rates of data transmission, when the transmission rate is low, the traffic channel is a low-rate channel, when the transmission rate is medium, the traffic channel is a medium-rate channel, and when the transmission rate is high, the traffic channel is a high-rate channel.

After the terminal acquires the wake-up signal, acquiring command parameter information included in the wake-up signal, determining whether the wake-up signal comprises a service channel identifier or not according to the command parameter information, determining the type of the service channel, and the like, and realizing data transmission based on the determined service channel identifier and the type of the service channel.

Step 304, if the wake-up signal includes a traffic channel identifier, the traffic channel identifier in the wake-up signal is obtained.

Referring to the above, the terminal uses the traffic channel to implement data transmission with the base station, the traffic channel identifier is an identifier for determining the unique traffic channel, the wake-up range may wake up only a single terminal, the traffic channel identifier may be a single traffic channel corresponding to a single terminal, the wake-up range may also wake up in an area manner, and the traffic channel identifier may be a traffic channel area identifier or a traffic channel identifier corresponding to a terminal area.

Specifically, if the wake-up mode is that a single terminal wakes up, the terminal directly acquires the relevant service channel identifier from the wake-up signal after acquiring the wake-up signal. If the wake-up mode is area wake-up, the terminal acquires the area identifier of the service channel from the wake-up signal or acquires the service channel identifier in the wake-up signal after determining that the terminal needs to wake-up.

And 306, if the wake-up signal does not include the service channel identifier, acquiring the service channel identifier pre-stored by the terminal.

Specifically, the terminal may first obtain and store the service channel identifier corresponding to the service channel, and when the terminal fails to obtain the service channel identifier by analyzing the wake-up signal, or when the terminal analyzes the wake-up signal to obtain that the wake-up signal itself does not include the service channel identifier, the terminal may directly obtain the pre-stored service channel identifier from the local storage of the terminal.

In this embodiment, by including the service channel identifier in the wake-up signal, the acquisition of the service channel identifier is achieved based on the wake-up signal, and the service channel corresponding to the terminal is designated, so that the time required for the terminal to acquire the service channel is reduced, thereby reducing the power consumption of the terminal. Further, in this embodiment, when the acquisition of the service channel from the wake-up signal fails, a corresponding target service channel is acquired from the service channel identifier pre-stored in the terminal, so that the success rate of data transmission can be improved.

In one embodiment, as shown in fig. 4, the wake-up range is a single terminal, and step 206, that is, determining whether to perform data access according to the wake-up range, if so, acquiring the service channel identifier includes:

step 402, judging whether the terminal identification of the single terminal is the same as the local terminal identification, if so, reading the single service channel identification in the wake-up signal.

And step 404, transmitting data to the traffic channel corresponding to the read single traffic channel identification.

Specifically, the terminal periodically acquires a wake-up signal from a wake-up channel, analyzes the wake-up signal to obtain a wake-up range, acquires a wake-up identifier corresponding to the wake-up range, wherein the wake-up identifier can be a terminal identifier or an area identifier, if the wake-up identifier is the terminal identifier, the terminal acquires a pre-stored terminal identifier, confirms whether the terminal identifier acquired from the wake-up signal is the same as the pre-stored terminal identifier, if the terminal identifier is the same as the pre-stored terminal identifier, the terminal is marked to wake up the terminal according to the wake-up signal, and the terminal wakes up according to the wake-up signal.

Further, for a single terminal, the base station may acquire an available service channel when forming a wake-up signal, and generate the wake-up signal according to the available wake-up channel identifier and the terminal identifier of the terminal to be woken up, so that the terminal may directly acquire the service channel identifier from the wake-up signal when determining to be woken up. Optionally, for single-terminal wake-up, when forming a wake-up signal, the base station may acquire a plurality of available service channels, form the wake-up signal with a plurality of service channel identifiers and terminal identifiers, and when acquiring a service channel to which data is accessed from the wake-up signal, the terminal may implement access to the data based on a preset access mode, for example, set a priority, and the terminal may implement access from high to low according to the priority, and when the service channel with high priority refuses to transmit the data, or fails to transmit the data by using the high priority channel, may implement data transmission by using other service channels, thereby improving the success rate of data transmission.

In this embodiment, the problem of power consumption increase caused by the fact that the terminal continuously transmits data can be effectively reduced by directly setting the terminal to be awakened. Further, a service channel identifier capable of realizing data access is arranged in the wake-up signal, the terminal directly acquires the service channel identifier based on the wake-up signal to realize data transmission, so that the success rate of data transmission is improved, and the problem of power consumption increase caused by the fact that the terminal is always in an available channel acquisition state is solved.

In one embodiment, as shown in fig. 5, the wake-up range is an area, and step 206, that is, determining whether to perform data access according to the wake-up range, if so, acquiring the service channel identifier includes:

step 502, determining whether the area identifier of the area is the same as the local area identifier, if so, reading at least one service channel identifier in the wake-up signal.

Step 504, a channel selection mode is obtained, a target service channel identifier is selected from at least one service channel identifier according to the channel selection mode, and data is transmitted to a target service channel corresponding to the target service channel identifier.

Specifically, the terminal periodically acquires a wake-up signal from a wake-up channel, analyzes the wake-up signal to obtain a wake-up range, acquires a wake-up identifier corresponding to the wake-up range, wherein the wake-up identifier can be a terminal identifier or a region identifier, if the wake-up identifier is the region identifier, the terminal acquires a local region identifier, confirms whether the region identifier acquired from the wake-up signal is the same as the local region identifier, if the region identifier is the same, the current wake-up is marked as regional wake-up, and the terminals in the region range realize wake-up.

Further, the channel selection mode is used for indicating a mode of selecting a traffic channel for transmitting data by the terminal, the terminal realizes the selection of the traffic channel according to the channel selection mode, and realizes the transmission of the data based on the selected channel. Specifically, after the area of the service channel is acquired, where the service channel of the area includes at least one service channel, the terminal implements data transmission according to at least one service channel in a preset manner, and the preset manner may implement data transmission in a sequential access manner, a random access manner, or the like.

Optionally, in the area wake-up, the multiple terminals may or may not belong to the same area, for example, two areas exist, D1 and D2 may exist, where D1 includes three terminals A1, A2, and A3, and area D2 includes four terminals B1, B2, B3, and B4, the terminals to be wake-up are, for example, A1, B2, and B4, or B2, and B3, and then the terminal identifier of the obtained terminal and the service channel identifier or the area identifier generate a wake-up signal, the terminal analyzes the service channel identifier or the area identifier from the wake-up signal, and implements data transmission according to the obtained service channel identifier or the area identifier in a preset manner, where the preset manner may be that data access may be implemented according to a priority of the service channel, or data access may be performed according to a service channel access sequence, or data access may be performed according to a sequence before and after a data transmission time of the terminal.

In this embodiment, the terminal and the area are divided into blocks, and when the terminal is awakened, the terminal is awakened based on the area, and a plurality of terminals are awakened at a time, so that data transmission is realized between the plurality of terminals and a plurality of service channels, and the problems that when the terminal is all awakened together, a large amount of data is blocked in the service channels to cause unsuccessful data transmission, and the terminal is always in a data transmission state to cause large power consumption are solved.

In one embodiment, step 504, namely obtaining a channel selection manner, selecting a target traffic channel identifier from at least one traffic channel identifier according to the channel selection manner, and transmitting data to a target traffic channel corresponding to the target traffic channel identifier includes: optionally, selecting the target traffic channel identity from the at least one traffic channel identity in a random manner; or selecting a target service channel identifier from at least one service channel identifier according to a preset sequence; or obtaining a channel evaluation result, determining an access priority according to the channel evaluation result, and selecting a target service channel identifier from at least one service channel identifier according to the access priority.

Specifically, when a plurality of terminals are awakened and the corresponding service channels are also a plurality of, the terminal and the service channels can be corresponding in a random access mode, for example, an ALOHA-type random access protocol is adopted to realize access.

Further, a sequential access manner may be adopted, for example, the number of terminals is 4, namely A1, A2, A3 and A4, the number of service channels is two, namely C1 and C2, and the access sequence of the corresponding service channels is C1 before C2, where when the terminal accesses the service channels, the terminal may access the service channels A1 first, then access the terminal A2 to C2, and then access the terminal A3 to C1 and A4 to C2. For the terminal, the sequence may be defined based on the time before and after receiving the data, that is, if the terminal A1 transmits the data to the service terminal first, the terminal A1 first accesses the service channel, and the terminal transmitted second is A3, A4, A2, and the access of the service channel is also realized in the sequence. It will be appreciated that the access sequence of the terminal may have other manners, for example, the sequence may be determined based on the data type, and the access sequence may be the first access with a high requirement on real-time performance, which is not limited.

Alternatively, the selection of the channel may be implemented in a manner based on the channel estimation result. The base station may evaluate the traffic channel according to the type of data transmitted in the channel, the rate of data transmitted, etc., determine the priority of the traffic channel based on the evaluation result, for example, the rate is greater than a first preset threshold, the congestion duration is less than the first congestion threshold and is a first level, the rate is less than or equal to the first preset threshold and is greater than or equal to a second preset threshold, the congestion duration is greater than or equal to the first congestion threshold and is a second level when the congestion duration is greater than or equal to the second congestion threshold, the rate is less than the second preset threshold, the congestion duration is greater than the second congestion threshold and is a third level, and then realize data transmission based on the determined priority, for example, assuming that the terminal includes terminals A1, A2, A3, traffic channels C1, C2, C3, and priority C2> C3> C1, then the terminal can realize data transmission by using the traffic channel first and then realize data transmission by using C3 or C1 if C2 cannot access data further.

Optionally, the adopted channel selection mode may be included in the wake-up signal, the terminal analyzes the wake-up signal to obtain the channel selection mode, or may be pre-stored in a local storage, the terminal acquires the channel selection mode from the current storage when the terminal needs to transmit data, and the base stations of the channel selection mode of the local storage are synchronized.

In this embodiment, adjustment of the data transmission traffic channel is implemented by using random, sequential, based on the evaluation result, etc., so that congestion caused by data transmission can be effectively reduced, and the problem of large power consumption caused by that the terminal is always in a data transmission state can be reduced.

In one embodiment, step 502, namely determining whether the area identifier of the area is the same as the local area identifier, if so, reading at least one traffic channel identifier in the wake-up signal includes: and reading the channel type and the channel sequence number in the wake-up signal.

In view of the foregoing, the terminal may be configured to perform area division with the traffic channel, where the division rule may be of various kinds, for example, according to a distance from the base station, a type of the terminal, a type of data transmitted by the terminal, and the like. When the traffic channel is divided, the type of data transmitted by the terminal may be divided, or the terminal itself may be divided. Specifically, the division may be performed according to the data rate transmitted by the terminal, for example, if the transmission is performed at a low rate, the traffic channel transmitting the data is divided into a fourth category, for example, a traffic channel with a channel bandwidth of 62.5kHz is divided into a fourth category, if the transmission is performed at a medium rate, the traffic channel with a channel bandwidth of 125kHz is divided into a fifth category, and if the transmission is performed at a high rate, the traffic channel with a channel bandwidth of 250kHz is divided into a sixth category. Alternatively, the division may be performed based on the data type, for example, if the transmitted data is regular data, for example, if it is determined whether the current device is at the original location, the corresponding traffic channel is divided into a fourth category, if the data is collected but the real-time requirement is not strict, the corresponding traffic channel is divided into a fifth category, and if the data is temporary important data, the corresponding traffic channel with high data requirement may be divided into a sixth category.

The base station may set that the terminal area corresponds to the traffic channel area, for example, the first class corresponds to the fourth class, or the first class corresponds to the fifth class, and the specific corresponding mode is not limited, where the wake-up signal may only include the terminal area related identifier, and after the terminal area identifier is obtained by parsing, the traffic channel related identifier may be obtained, so that data transmission may be implemented. And then acquiring a service channel area corresponding to the terminal area to be awakened after determining the terminal area to be awakened, generating an awakening signal according to the acquired area identification of the terminal area and the area identification of the service channel area, and obtaining the identification of the service channel area by analyzing the acquired awakening signal by the terminal.

Further, the terminal area may not be set to correspond to the service channel area, and the identifier of the relevant area may be selected when the wake-up signal is generated, for example, the wake-up signal is required to be a first class, and at this time, the desired service channel is a fifth class, and the wake-up signal is generated according to the first class and the fifth class, so that the terminal may still realize data transmission after obtaining and analyzing the wake-up signal.

Further, the number of the traffic channel regions and the terminal regions is not limited, and the number of the traffic channel regions and the terminal regions may be different, for example, two traffic channel regions may correspond to three terminal regions, and two traffic channel regions may be a fourth category and a fifth category, three terminal regions, a first category, a second category, and a third category, respectively.

Further, the terminal periodically acquires the wake-up signal and analyzes the wake-up signal to obtain a service channel identifier, if the service channel identifier is an area identifier, the sequence number of the service channel included in the service channel classification corresponding to the area identifier can be acquired, and data transmission can be realized by determining the service channel according to the service channel sequence number, for example, the currently acquired area identifier indicates that the service channel area is a fourth classification, wherein the fourth classification includes three service channels, the channel sequence numbers are respectively C1, C2 and C3, the terminal acquires the service channel for realizing data transmission according to a preset mode as a C1 service channel, and acquires the channel sequence number C1 based on the acquired service channel to realize data transmission.

In one embodiment, step 208 of transmitting data to the traffic channel corresponding to the traffic channel identification comprises: acquiring period information in the wake-up signal, judging whether the current time is matched with the period information, and if not, not responding to the wake-up signal; if yes, transmitting data to the service channel corresponding to the service channel identification.

Specifically, the terminal periodically acquires a wake-up signal from the wake-up channel, determines a service channel for realizing data transmission based on the wake-up signal, and then realizes data transmission based on the acquired service channel. Regarding data transmission, whether the transmission is successful or not can be determined to determine whether retransmission is needed, specifically, after the data transmission is achieved, if feedback that the transmission is successful is not received within a period of time, the terminal indicates that the current data transmission fails. Or the same wake-up signal issued by the base station is received again in the period, which indicates that the data transmission fails. Or receiving feedback that the base station returns to and fails to transmit data, when determining that the data transmission fails, the data transmission can be realized again after receiving the wake-up signal issued by the base station, or the terminal itself can periodically and repeatedly transmit the data, which is not limited. And setting a success identifier when the successful data transmission is determined.

Specifically, the base station periodically realizes terminal wakeup to realize data transmission, and when realizing wakeup, the base station can add period information into a wakeup signal, for example, the period information can be represented by a period identifier, for example, on the basis of one hour, and the base station divides the period into one hour to form different periods with 10 seconds as a period, wherein the period information is in a first period of 0-10S, the period information is in a second period of 10-20S, the period information is in a second period of S2, and the like. The terminal acquires the wake-up signal, analyzes the wake-up signal to obtain period information Sn, further acquires whether information is sent in the period of Sn-1, namely, determines whether data transmission success identification exists in the period of Sn-1, if the successful data transmission is confirmed, the wake-up signal can be ignored, and the terminal can also feed back the successfully transmitted information to the base station, so that the base station does not issue a wake-up signal to wake up a command of the terminal for collecting the same data.

In one embodiment, as shown in fig. 6, a data transmission method is provided, and the method is applied to the base station in fig. 1 for illustration, and includes the following steps:

step 602, generating a wake-up signal according to the wake-up range or the wake-up range and the traffic channel identifier.

Referring to the above, the base station defines a wake-up channel and at least one traffic channel, where the wake-up channel is a channel used by the base station to implement wake-up signal transmission, and the traffic channel is used for data transmission between the terminal and the base station. And the base station periodically generates a wake-up signal to wake up the terminal.

Alternatively, the base station may set a period, for example, with 10s as a period, collect different types of data corresponding to different periods, for example, 0-10s as a first period, collect the first type of data, 10-20s as a second period, collect the second type of data, 20s-30s as a third period, collect the third type of data, and so on. Referring to the above, the terminal and the traffic channel may be divided, for example, into a first class … … and a sixth class, the terminal may be corresponding to the traffic channel, for example, may be divided based on a transmission data type, for example, the data transmitted by the first class and the fourth class is regular data, and the first class may be corresponding to the fourth class. Similarly, the period may also be corresponding to the classification, for example, the period identifier Sn of the period is corresponding to the first classification or the fourth classification when the conventional data needs to be collected in the current period, and after the base station determines the current collection period, the base station may determine the current collected terminal and the corresponding traffic channel based on the collection period, and generate the wake-up signal based on the obtained terminal and the traffic channel.

The period may correspond to the single terminal to be awakened, that is, the area awakening and the single terminal awakening may correspond to the period, and in the first period, the area awakening or the single terminal awakening may be corresponding to the area awakening, for example, in the nth period, the single terminal data needs to be acquired, at this time, the terminal identifier and the service channel identifier corresponding to the nth period are acquired, and the period identifier, the terminal identifier, the service channel identifier and the like are generated to generate the awakening signal.

Optionally, for single-terminal wake-up to be implemented, when wake-up is required, an available service channel is acquired, one or more service channels or already divided service channel areas are acquired, and a wake-up signal is generated according to the acquired terminal identifier, the service channel identifier and the service channel area identifier.

Further, the base station may initiate a data acquisition signal at any time according to the need, and after determining whether a single terminal needs to be awakened or an area needs to be awakened, set at least one traffic channel or traffic channel area corresponding to the awakened terminal or area, and generate an awakening signal based on a terminal identifier, an area identifier, a traffic channel identifier, and the like.

Step 604, accessing a wake-up signal to a wake-up channel, where the wake-up signal is used to wake up the terminal in the wake-up range, and instruct the wake-up terminal to transmit data to a traffic channel corresponding to the traffic channel identifier.

Specifically, after generating the wake-up signal, the base station can access the wake-up signal to the wake-up channel, the terminal can periodically acquire the wake-up signal from the wake-up channel and analyze the wake-up signal, the terminal acquires the wake-up range from the wake-up signal, realizes wake-up based on the wake-up range, and realizes data transmission based on the service channel identifier acquired from the wake-up signal.

The base station periodically generates a wake-up signal and accesses the wake-up signal, and the period is as short as possible, so that the power consumption of terminal interception is effectively reduced.

In step 606, the service data transmitted by the terminal through the service channel is received.

Specifically, the terminal obtains a wake-up signal from a service channel, obtains a wake-up range based on analysis of the service signal to wake up, further analyzes the wake-up signal to obtain a service channel identifier, and when the terminal determines to realize data transmission, the terminal receives data of the service channel corresponding to the service channel identifier, which is transmitted to the terminal, based on the obtained content related to the service channel identifier by the base station. Or when the base station generates the wake-up signal, the base station does not include the service channel identifier in the wake-up signal, the terminal cannot obtain the effective service channel identifier based on the wake-up signal, and at this time, the receiving terminal receives data transmitted by the service channel corresponding to the pre-stored service channel identifier.

In this embodiment, for the terminal desiring to wake up, the terminal identifier and the corresponding service channel identifier are directly set in the wake-up signal, so that the terminal directly wakes up the terminal desiring to wake up according to the wake-up signal, and the terminal can realize data transmission based on the service channel identifier, and directly wakes up the terminal based on the wake-up signal, so as to reduce the problem of excessive power consumption caused by whether the terminal is always in a certain wake-up state or not, and also reduce the problem of excessive power consumption caused by whether the terminal is always in a data transmission state. And distinguish the wake-up channel and business channel, make the wake-up channel that realizes waking up distinguish with the business channel that realizes data transmission, different channels realize different functions, reduce the situation that the data transmission fails, is crowded caused by the conflict of the data, thus reduce the terminal station and keep in the too high problem of power consumption that the data transmission state causes all the time.

In one embodiment, as shown in fig. 7, step 602 of generating a wake-up signal according to a wake-up range or a wake-up range and a traffic channel identification includes:

step 702, if the wake-up range is a single terminal, acquiring a service channel identifier of an idle service channel, and generating a wake-up signal representing the wake-up range of the single terminal according to the acquired service channel identifier and the terminal identifier.

Step 704, if the wake-up range is the area, acquiring a service channel identifier corresponding to the area identifier of the area, and generating a wake-up signal representing the wake-up range of the area according to the area identifier and the service channel identifier.

Specifically, when the terminal is awakened, the desired awakening can be single terminal awakening or area awakening. For single-terminal awakening, a currently available service channel can be acquired, the service channel is selected according to a preset mode, and an awakening signal is generated according to the service channel identification and the terminal identification. For example, the obtained service channel is one, the base station generates a wake-up signal according to the obtained service channel identifier and the terminal identifier to be waken, or the obtained service channel is a plurality of service channels or areas, and then the base station generates the wake-up signal according to the obtained terminal identifier and the plurality of service channel identifiers or area identifiers.

Optionally, for area wake-up, referring to the above, different areas may be divided for the terminal and the traffic channel according to different data transmission rates, data types, and the like, for example, the terminal may be divided into a first category, a second category, a third category, and the like, the traffic channel may be divided into a fourth category, a fifth category, and the like, and the terminal category may be corresponding to the traffic channel category based on the data type, for example, the first category corresponds to the fourth category, and the traffic channel area is determined after determining the terminal area to be wake-up, and the wake-up signal is generated according to the terminal category identifier and the traffic channel category identifier. The traffic channel region may also be determined based on the evaluation result, for example, the traffic channel may be evaluated based on the traffic channel transmission rate, the congestion duration, etc., the traffic channel region used to transmit data may be determined according to the evaluation result, and the wake-up signal may be generated based on the obtained terminal region identifier and the channel region identifier.

Further, for the case of multiple traffic channels, the base station may include the channel selection manner together in the wake-up signal, so that the terminal can directly implement the selection of the traffic channel based on the channel selection manner obtained by parsing the wake-up signal.

In this embodiment, the problem of power consumption increase caused by the fact that the terminal continuously transmits data can be effectively reduced by directly setting the terminal to be awakened.

In one embodiment, as shown in fig. 8, the data transmission method includes:

step 802, acquiring transmission state parameters of transmission data in at least one service channel in a preset period; the transmission status parameter includes a transmission rate.

Specifically, the traffic channel receives data transmitted by the terminal, the base station monitors transmission status parameters of data transmission in the traffic channel, such as a transmission rate, a congestion duration, and the like, determines transmission capacity of the current traffic channel according to the transmission rate, determines the transmission capacity of the current traffic channel according to the transmission status parameters, and can determine priority of the traffic channel according to the transmission capacity.

Step 804, evaluating the service channel according to the transmission rate to obtain a service channel evaluation result; the service channel evaluation result is the access priority of the service channel.

Specifically, the access priority is used to determine the order in which the terminals select the transmission traffic channels. The service channel receives the data transmitted by the terminal, the transmission state parameters are obtained by monitoring the transmission state of the data transmitted in the service channel, after the relevant data of the service channel are obtained by monitoring, the transmission state of the service channel is determined according to the relevant data to further order the priority of the service channel, and the priority of the service channel can be adjusted according to the transmission rate and the congestion duration, for example, the original priority is C1> C2> C3, the best transmission performance of the current service channel is obtained according to the monitored data and is C3, then C1 and finally C2, the priority of the channel at the moment is C3> C1> C2, and the terminal can be used for accessing the corresponding service channel according to the requirement to realize data transmission based on the adjusted priority of the service channel.

Optionally, the success rate and the data loss rate of the data transmission of the traffic channel may also be monitored, and the priority of the traffic channel may be adjusted according to the data success rate and the data loss rate, for example, the priority of the traffic channel may be increased when the power reaches a first threshold, the priority may be further increased when the power reaches a second threshold, the priority of the traffic channel may be reduced when the data loss rate reaches a third threshold, and the priority of the traffic channel may be further reduced when the power reaches a fourth threshold. Further, the success rate of transmitting data and the data loss rate may also be considered at the same time, for example, when the success rate of transmitting data reaches a first threshold value and the data loss rate is smaller than a third threshold value, the priority of the traffic channel is increased. Optionally, the adjustment of the priority of the traffic channel may also be performed by parameters such as the success rate of data transmission of the terminal, the amount of data that can be received in the traffic channel period, etc., for example, whether there is an idle bandwidth when data is transmitted in the traffic channel may be monitored, if so, the priority may be adjusted, or the type of data transmitted in the traffic channel may be adjusted, for example, the original low-rate data is adjusted to medium-rate data.

It can be understood that, after the transmission status parameter of the traffic channel is monitored, it is determined that the current traffic channel cannot meet the data transmission requirement, and then the traffic channel can be further added to share the data transmission.

In one embodiment, as shown in fig. 9, fig. 9 is a timing chart of a data transmission method in one embodiment, in which a base station and a terminal are mainly included.

The base station firstly determines a wake-up range, namely, whether a single terminal is waken up or a regional wake-up is determined, and further determines a service channel for transmitting data, wherein the service channel can be one or a region, generates a wake-up signal according to the acquired terminal identification and service channel identification of the terminal, and further accesses the wake-up signal into the wake-up channel.

The terminal periodically acquires a wake-up signal from a wake-up channel, analyzes the acquired wake-up signal, analyzes the wake-up signal to obtain a wake-up range, determines whether a terminal identifier is the same as a local terminal identifier if the wake-up range is single-terminal wake-up, acquires a service channel identifier from the wake-up signal if the terminal identifier is the same as the local terminal identifier, and transmits data to a service channel corresponding to the service channel identifier. If the wake-up range is the area, determining whether the area identifier obtained from the analysis signal is the same as the local area identifier, if so, obtaining the area identifier of the service channel, and realizing data access according to a preset mode. The preset mode comprises random access, sequential access and access based on an evaluation result.

If the terminal determines that the wake-up range is the same as the local wake-up range and the service channel identification is failed to be acquired from the wake-up signal, the service channel identification is acquired from the current storage, and data is transmitted to the service channel corresponding to the service channel identification stored at the current time.

The base station receives the data transmitted by the terminal, evaluates the service channel according to the state parameter of the data transmitted by the service channel, the evaluation result is used for adjusting the access sequence of the service channel, and the terminal realizes the data transmission based on the adjusted access sequence.
