The following describes in detail the embodiments of the present application with reference to the drawings attached hereto.

In the following description, for purposes of explanation rather than limitation, specific details are set forth such as the particular system architecture, interfaces, techniques, etc., in order to provide a thorough understanding of the present application.

The term "and/or" herein is merely an association relationship describing an associated object, and means that there may be three relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship. Further, the term "plurality" herein means two or more than two. In addition, the term "at least one" herein means any one of a plurality or any combination of at least two of a plurality, for example, including at least one of a, B, C, and may mean including any one or more elements selected from the group consisting of a, B, and C.

Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a data transmission method according to an embodiment of the present application.

Specifically, the following steps may be included:

step S11: the communication terminal receives a first communication service notification sent by the communication equipment, wherein the first communication service notification carries the time of the next communication service.

The communication terminal according to the embodiments of the present disclosure may be various mobile communication devices, such as a mobile phone, an intercom, a vehicle-mounted computer, a handheld computer, and the like, and the communication device may be a base station, and the like. The data transmission from the communication equipment to the communication terminal is down transmission, and the data transmission from the communication terminal to the communication equipment is up transmission.

Wherein the first communication service notification may be carried by signaling, for example, by control signaling. The first communication service notification may be a service notification with an activation function, such as activation signaling, or a service notification with specific service requirements, such as pull-up signaling, etc. The next communication service may be a pull-up service or a down-send service. The pull-up service may be a pull-up of GPS data, or a pull-up of other data related to the communication terminal, and the specific pull-up data is not specifically defined here, and the issue service may be an issue task instruction, or certainly may be an issue of specific data to the communication terminal, and therefore, the specific data type of the issue service is not specifically defined here. The channel for receiving the first communication service notification under the communication device may be a control channel, where the control channel refers to a channel on which the communication terminal is registered, but in other embodiments, the communication terminal may also receive the first communication service notification under another channel, and therefore, no specific description is made here as to what channel the communication terminal receives the first communication service notification. After receiving the first communication service notification with the activation function, the communication terminal uploads a response to the communication device at a next time unit of a channel for receiving the notification, which indicates that the communication terminal has successfully received the first communication service notification delivered by the communication device. If the communication terminal receives the first communication service notification with specific service requirements, the corresponding data of the notification is uploaded at the next time unit of the same channel for receiving the notification.

Step S12: and according to the first communication service notice, starting to monitor the first channel a plurality of time units before the next communication service.

Optionally, if the system sets a fixed location of the first channel, the first channel may be monitored at the fixed location before the next communication service, where the fixed location includes a time unit and a frequency band of the first channel. For example, the position of the first channel is set in advance as the secondary control channel. The auxiliary control channel and the control channel are located in the same frequency band of different time units. If the system does not set a fixed location for the first channel, then after receiving the first traffic notification, the monitoring for all time units may be selected to be turned on to start monitoring for the first channel whose location is unknown. Of course, if the first communication service notification further includes the position of the first channel temporarily allocated by the communication device, the communication terminal may start monitoring the first channel at the position of the first channel until the time of the next communication service. Therefore, as to whether the location of the first channel is previously fixed or temporarily allocated or unknown, the monitoring of the first channel can be started according to the time of the next communication service carried by the first communication service notification after the first communication service notification is received.

Wherein, the plurality of time units can be 1 time unit or 2 or more time units. The determination manner of the plurality of time units may be the number of time units in which the first channel is located. Specifically, one time unit may be one time slot, and the monitoring of the first channel is started several time slots before the next communication service according to the first communication service notification. The number of time units is 2, that is, 1 time slot in which the first channel is located is separated between the time slot in which the monitoring of the first channel is started and the time slot in which the next communication service is located, for example, if one time frame includes two time slots and the first channel is located in the second time slot, 1 second time slot is separated between the time slot in which the monitoring of the first channel is started and the time slot in which the next communication service is located. If the first channel is located in the second timeslot of the time frame, the time of the next communication service carried by the next communication service notification should also be in the second timeslot. In other embodiments, the number of time units may also be the total number of the specific first time slot and the specific second time slot, for example, the number of time units is 2, that is, 1 time slot is separated between the time slot where the monitoring of the first channel is started and the time slot where the next communication service is started, and the first time slot is also used. Therefore, the specific determination manner of the time units can be various and is not specifically defined herein.

Monitoring the first channel means that data or instructions sent by the communication device using the first channel can be received, that is, if the communication terminal does not monitor the first channel, the communication terminal cannot receive the data or instructions sent by the communication device using the first channel, and the like. The monitoring of the first channel according to the embodiment of the present disclosure may be monitoring a time unit in which the first channel is located.

Step S13: and carrying out data transmission with the communication equipment by using the first channel to complete the next communication service. And starting a preset power saving strategy of the communication terminal under the condition that the communication terminal does not start monitoring the first channel.

Just as the communication terminal is monitoring the first channel, it can receive instructions or data sent from the first channel by the communication device. For example, when monitoring the first channel and receiving a pull-up signaling sent by the communication device, the communication terminal uses the first channel to upload pull-up data corresponding to the pull-up signaling to the communication device, so as to complete a pull-up service. In this example, the next communication service is the pull-up service corresponding to the pull-up signaling. Of course, if the communication terminal monitors the first channel and if the communication device directly issues data to the communication terminal, the communication terminal directly receives the issued data, that is, completes data transmission with the communication device, in this example, the next communication service is the issued service. The next communication service is not limited to the down-sending service and the up-pulling service, and the traffic between other communication terminals and the communication device may be the next communication service according to the embodiment of the present disclosure.

In the embodiment of the present disclosure, the monitoring of the first channel may be in an on state, or may be in an off state, that is, in an unopened state. Whether to start monitoring the first channel is mainly determined by the next communication service time carried by the first communication service notification. When the communication service is not required to be performed by using the first channel, the resource is wasted if the first channel is monitored all the time. Therefore, in the embodiment of the present disclosure, the preset power saving policy of the communication terminal may be turned on when the monitoring of the first channel is not turned on by the communication terminal. Of course, when the communication terminal starts monitoring the first channel, part of the preset power saving policy may be closed, or the entire preset power saving policy may be closed, and no specific provisions are made herein.

According to the scheme, the communication terminal controls the starting of the monitoring of the first channel through the first communication service notification, wherein the preset power saving strategy of the communication terminal is started under the condition that the monitoring of the first channel is not started, the first channel is not required to be monitored at all times in the mode, the corresponding preset power saving strategy can be started under the condition that the first channel is not monitored, and the power saving effect of the communication terminal is achieved.

Optionally, the first communication service notification further includes a communication resource location of the next communication service. The communication resource position of the next communication service comprises a time unit and/or a frequency band of a channel required to be used for the next communication service. Wherein, the channel at the position of the communication resource is the first channel. I.e. the first communication service announcement includes the location of the first channel. Of course, the location of the first channel used in any one communication may be changed, that is, the location of the first channel is not fixed, and the communications device may select the location of the first channel according to the location usage status of the communications resource. For example, the time unit in which the channel that needs to be used by the next communication service is included in the first communication service notification does not include the frequency band, that is, the communication terminal needs to start the channel in the default frequency band that needs to be used by the next communication service between the next communication services, or monitor all frequency bands of the time unit in which the channel that needs to be used.

According to the scheme, the time and the position of the next communication service are carried in the first communication service notification, namely the position of the first channel in the communication at different moments is not fixed, and the channel used by the next communication service can be flexibly adjusted according to the use condition of the channel, so that the communication efficiency between the communication terminal and the communication equipment is improved. Moreover, the position of the next communication service is determined, and compared with the condition that the communication terminal is started to monitor all time units and frequency bands, the power consumption is reduced to a certain extent.

In some disclosed embodiments, a communication terminal receives a first communication service announcement on a second channel or a first channel. The second channel and the first channel are in the same or different time units and/or frequency bands. That is, the first channel and the second channel may be located in the same frequency band or different frequency bands of the same time unit, or located in the same frequency band or different frequency bands of different time units. Of course, if the first channel and the second channel are located in the same frequency band of the same time unit, it is indicated that the first channel and the second channel are actually the same channel. Wherein, the second channel and the first channel are in the same frequency band of different time units. The second channel is identical to the first channel except for the time unit in which it is located. Usually, time division multiple access and frequency division multiple access are used jointly, i.e. not only in time but also in frequency. The second channel and the first channel are located in the same frequency band of different time units, so that the frequency does not need to be switched in the process of switching from the second channel to the first channel, and the efficiency is improved. Optionally, the first channel and the second channel are located in different time units, but in the same frequency band. Wherein, when the communication terminal receives the first communication service notification on the first channel, before executing step S12, the following steps are further executed: the first is to use the first channel to execute the communication service corresponding to the first communication service notification, and the second is to close the monitoring of the first channel after the execution of the communication service corresponding to the first communication service notification. After the communication service corresponding to the first communication service notification is executed, a preset power saving strategy corresponding to the communication terminal needs to be executed. I.e. the first communication service announcement is a service announcement with specific service requirements.

In the embodiment of the present disclosure, if the first communication service notification is a service notification with an activation function, that is, has a function of activating the monitoring of the communication terminal on the first channel, the communication device issues the first communication service notification using the second channel, that is, the communication terminal receives the first communication service notification in the second channel. I.e. the second channel receiving the service announcement with the active function is not the same channel as the first channel. If the first communication service notification is a service notification with specific service requirements, the communication equipment uses a first channel for issuing, and the communication terminal uses the first channel for receiving. That is, the second channel and the first channel may be the same channel, that is, when the communication terminal is monitoring the first channel, the communication terminal receives the first communication service notification and executes the communication service corresponding to the first communication service notification, after the communication service is executed, the monitoring of the first channel is closed, the preset power saving policy is simultaneously turned on, and the monitoring of the first channel is turned on again in a plurality of time units before the next communication, and the preset power saving policy is simultaneously turned off.

Here, the second channel may be a channel which was last communicated with the communication terminal and is still monitored by the current communication terminal, and if the communication terminal has not communicated with the communication device before, the second channel may be a channel registered by the communication terminal, that is, a control channel. For example, the first channel used for the next communication according to the embodiment of the present disclosure may be a second channel for the next communication.

When the first channel is never used before or after receiving the notification of stopping using the first channel, if the next communication service needs to use the first channel, the communication device needs to send the first communication service notification with the activation function.

The second channel described in the embodiment of the present disclosure may be a channel that is always monitored by the communication terminal, that is, when there is a next communication service that needs to be performed using the first channel, a notification for activating the first channel is issued to the second channel, that is, a communication service notification is activated. After the first channel is activated, if data of the communication terminal needs to be pulled up subsequently, the first channel can be directly used to send a pull-up notification to the communication terminal, so that the communication terminal uses the first channel to upload data corresponding to the pull-up notification to the communication device.

Wherein the second channel may be a control channel and the first channel may be a secondary control channel. The auxiliary control channel and the control channel are located in the same frequency band of different time units. The control channel is mainly used for sending and receiving control signaling and performing part of services. Referring to fig. 2, fig. 2 is a schematic diagram illustrating communication between a general communication terminal and a communication device according to an embodiment of the data transmission method of the present application. As shown in fig. 2, a common procedure for data transmission using a control channel is as follows: the communication terminal sends an uplink request at the point A, the communication equipment sends a downlink response at the point B, the communication equipment sends a downlink request at the point C, and the communication terminal can send an uplink response at the point D. Regarding the division of the channel time unit, there may be differences according to the development of the technology or according to different network requirements, and the embodiment of the present disclosure takes a digital trunking standard for data mobile radio/police, which uses a time division multiple access frame structure with two time slots, which is divided into an uplink direction and a downlink direction, and each time slot is 30ms, wherein a control channel occupies a part of a frequency band in a first time slot, and an auxiliary control channel occupies a part of a frequency band in a second time slot.

By starting to monitor the first channel before the time of the next communication service carried by the first communication service notification, and enabling the second channel and the first channel to be located in different time units, that is, by starting to monitor the time unit of the first channel before the time of the next communication service, the common monitoring overhead, such as the overhead of power resources and the like, of the time unit of the first channel is reduced.

In some disclosed embodiments, the time of the next communication service carried by the first communication service announcement includes a time interval from the next communication service. For example, if the time interval field carried in the first communication service notification is 3, it indicates that three time units are separated. Of course, the time unit may be calculated by only calculating the number of the first channels, and in the above example, one frame structure includes two time slots, where the first channel is in the second time slot, and the time interval is 3, which indicates that three frame structures are separated by 3 first time slots and 3 second time slots. The starting point of the time interval may be a time point issued by the communication device, or may be calculated by adding time spent in the issuing process of the first communication service notification, that is, from a time point when the communication terminal receives the first communication service notification. That is, the next communication service time is calculated according to the time interval and the current time. The current time is the starting point of the time interval, that is, the time when the communication device issues the first communication service notification or the time when the communication terminal receives the first communication service notification. In general, a time interval between a time when the communication device issues the first communication service notification and a time when the communication terminal receives the first communication service notification is fixed, and certainly, the time interval may change due to special reasons such as different transmission distances or different network signals, and may be ignored in the embodiment of the present disclosure, or may be dynamically adjusted, that is, according to that before the first communication service is first sent, the communication device issues a time determination notification, where the time when the time determination notification is issued is carried, and after the communication terminal receives the time determination notification, the time when the communication terminal receives the time determination notification itself is fed back to the communication device in a preset manner, so that the communication device and the communication terminal can know the time required for data transmission between the communication device and the communication terminal. Of course, in other embodiments, the specific time of the next communication service may be directly carried.

By determining the time unit of the next communication service time in a time interval manner, the communication device can determine at what time to start monitoring the first channel according to the time, and if the time of the next communication service is not carried, the communication device can only start monitoring the first channel immediately after receiving the notification of the first communication service, so as to prevent missing the next communication service between the communication device and the communication device. Of course, when monitoring the first channel is started in a plurality of time slots before the next communication service, the preset power saving strategy of the communication terminal can be closed. By closing the preset power saving strategy, the communication terminal can be ensured to be capable of carrying out normal data transmission with the communication equipment in the first channel.

As described above, according to the first traffic notification, the monitoring of the first channel is started several time units before the next traffic. That is, the monitoring of the first channel is started in advance by a preset number of time units, wherein the number of time units is less than or equal to the time interval carried by the first communication service notification and apart from the next communication service. Accordingly, embodiments of the present disclosure are not specifically specified with respect to determining a point in time at which to monitor for an activation. After calculating the time point of the next communication service and determining the time for starting the monitoring of the first channel, a timer is started, so that the monitoring of the first channel is started immediately after the time point for starting the monitoring of the first channel is reached.

By starting monitoring of the first channel in a preset number of time units before the next communication service starts instead of immediately starting monitoring of the first channel after receiving the first communication service notification, power consumption of the time unit in which the first channel is monitored can be reduced to a certain extent. And, the monitoring of the first channel is not started at the same time point of the next communication service, which can prevent the missing of the service communication with the communication device.

In some disclosed embodiments, the attributes of the first communication service notification and the second communication service notification may be the same or different, for example, the first communication service notification is a notification with an activation function, and the second communication service notification may be a notification with a specific service requirement, for example, a pull-up notification, where the attribute of the first communication service notification is activation and the attribute of the second communication service notification is a pull-up service attribute, so that they are different, or the first communication service notification and the second communication service notification are both notifications with a specific service requirement, for example, both the pull-up notifications have the same attribute. It should be noted that, when the attribute of the first communication service notification and the attribute of the second communication service notification are the pull-up service attributes, in order to ensure that the communication terminal can receive the notification successfully, only when the communication terminal monitors the first channel, the communication device uses the first channel to send the notification to the communication terminal, so as to notify the communication terminal of the next communication service time. Since the attribute of the notification is the pull-up service attribute, the communication terminal should upload the corresponding data of the notification to the communication device using the first channel after receiving the notification, and still need to calculate the time of the next communication service in order to start monitoring the first channel before the next communication service.

In some disclosed embodiments, the first communication service announcement is an active communication service announcement, and as described above, the active communication service announcement is used to activate monitoring of the first channel by the communication terminal. And receiving a second communication service notification sent by the communication equipment on the first channel, wherein the second communication service notification carries the time of the next communication service. Of course, the second communication service notification may also carry the service type of this time and/or the communication resource location of the next communication service, where the definition of the communication resource location is as described above, and is not described herein again. Similarly, the time of the next communication service may be a time interval or a specific service time point. The service type comprises a pull-up service type or a download data, and the like, wherein the pull-up service type comprises a pull-up object and some pull-up requirements for the pull-up object. The pull-up object can be a request for uploading communication terminal GPS data, and the pull-up request comprises encryption, encryption mode and the like. Data corresponding to the second communication service notification is transmitted to the communication device using the first channel. I.e. the data corresponding to this traffic type is transmitted to the communication device using the first channel. By receiving the second communication service notification within the time period for monitoring the first channel, data corresponding to the second communication service notification can be uploaded. And when the next service type is the downloading data and the communication terminal receives the data downloaded by the communication equipment, the next communication service is considered to be finished.

In some disclosed embodiments, communication service parameters carried by the first communication service notification and/or the second communication service notification are read, where the communication service parameters include a communication service index. The type of the communication service index may be a number, or may be a symbol having an identification function. For example, the traffic index may be a numerical cycle of 1-15. The communication service index in the first communication service notification with the activation function may be 0, which marks that it is the activation communication service notification, and the second communication service notification after the first communication service notification may start the identification at 1, and start the cycle from 1 after 15. And recording the first communication service notice and/or the second communication service notice corresponding to the communication service index so as to synchronize the communication service. That is, the communication terminal can know how many times the communication device has issued the communication service notification, the attribute of each communication service notification, the type of the communication service, and the like, and can perform feedback to the communication device if the communication device repeatedly transmits the communication service notification with the same communication service index, or, when the communication terminal receives that the service index in the communication service notification is not continuous with the service index carried in the previous communication service notification, the notification corresponding to the communication service index that is not received may be lost, and at this time, the communication terminal can communicate with the communication device specifically, thereby reducing the occurrence of errors, and the like.

In some disclosed embodiments, if the service notification sent by the communication device is not received at the time of the next communication service, a request is sent to the communication device so that the communication device sends the first communication service notification to the communication terminal again. The service notification sent by the communication equipment is not received at the time of the next communication service, which indicates that the communication service between the communication terminal and the communication equipment is out of step and needs to be synchronized again. And, although already out of service, the communication terminal needs to monitor the first channel and the second channel simultaneously. In case the service notification arrives later than the calculated time due to network delay or the like. Wherein the first communication service notification is a notification with an activation function. And the communication terminal sends a request to the communication device on the second channel. The request includes a service type corresponding to a service completed last time, time for indicating a next communication service, a communication service index, and the like. The communication device looks up the service notification that the communication service index should have received but not received according to the data in the request. After the first communication service notice with the activation function is issued, the service notice is issued. After receiving the first communication service notification and/or the second communication service notification, the communication terminal specifically operates in the above manner. By sending a request to the communication device, it is possible to return to normal communication again.

Wherein the presetting of the power saving policy includes turning off a means for monitoring the first channel. The specific preset power saving policy may be determined according to specific requirements, and the specific preset power saving policy is not specifically defined herein. After the next communication service is completed, at least one of shutting down monitoring of the first channel to communicate with the communication device using a channel other than the first channel is also performed. Of course, since the second communication service notification carries the time of the next communication service, after the time of the next communication service is calculated, the timer is started to restart the monitoring of the first channel in a preset number of time units before the next communication service. After receiving the communication service ending sent by the communication equipment, the monitoring of the first channel is closed, and the timer is not opened any more until the second channel receives the first communication service notification with the activation function again, and the monitoring of the first channel is started according to the next communication service time carried by the second channel. By shutting down monitoring of the first channel during periods when no traffic is required, power consumption resulting from monitoring the first channel may be reduced. And secondly, starting a preset power saving strategy of the communication terminal. That is, in the embodiment of the present disclosure, the monitoring of the first channel is started and the preset power saving policy is turned off synchronously, and the monitoring of the first channel is turned off and the preset power saving policy is turned on synchronously, but may not be the same. That is, the monitoring of turning on or off the first channel and the turning on or off of the preset power saving policy may be performed in the same time unit or in different time units, which is not specifically defined herein.

To better illustrate the technical solutions provided by the embodiments of the present disclosure, the following examples are illustrated: referring to fig. 3, fig. 3 is a first schematic view illustrating communication between a communication terminal and a communication device according to an embodiment of the data transmission method of the present application. As shown in fig. 3:

the communication terminal initially listens to only the second channel and does not listen to the first channel. Wherein the first channel and the second channel are different. The communication equipment issues a first communication service notification to the communication terminal, wherein the first communication service notification is an activated communication service notification, and after receiving the notification, the communication terminal uploads a response notification to the communication equipment, which indicates that the communication terminal has received the notification. Then, according to the service index in the first communication service notification, the communication service synchronization is carried out, and the next communication service time is calculated. And starting a timer after knowing the time of the next communication service, and monitoring the first channel and the second channel simultaneously after reaching the monitoring time point of the first channel. And after the appointed time point of the next communication service is reached, the communication equipment uses the first channel to send the second communication service notification, and then the communication terminal uploads the data corresponding to the second communication service notification on the first channel. After the uploading is finished, the monitoring of the first channel is closed, the monitoring of the second channel is kept, the time of the next communication service is calculated according to the time of the next communication service carried by the notification of the second communication service, and a timer is started to cycle in sequence.

Referring to fig. 4, fig. 4 is a schematic diagram illustrating communication between a communication terminal and a communication device according to an embodiment of the data transmission method of the present application. As shown in fig. 4:

and if the communication terminal does not receive the service notification, such as the second communication service notification, sent by the communication equipment in the preset next communication service time, the communication terminal determines that the service is out of step.
