Description

TECHNICAL FIELD

[0001] The present application relates to the field of communication technology, in particular to a low power saving mode (PSM) sleep method and related device. BACKGROUND

[0002] Currently, after a communication module (such as a Cat1 module) opens a PSM function, it usually enters an idle state and waits for a 3324 timer to expire before entering PSM sleep. There are multiple ways to wake up the communication module, usually by pulling down the PSM_INT pin to wake up the communication module, or actively waking up the communication module by pressing the power key, or the network side wakes up the communication module through a tracking area update (TAU) timer.

[0003] The user can control the PSM sleep to wake up at any time by operating the PSM_INT pin or the power key, but cannot control the time when the communication module enters PSM sleep. In the case that the user's service is not completed but the 3324 timer has expired, the communication module will enter PSM sleep, resulting in user service failure. If the 3324 timer time is lengthened, the communication module cannot enter PSM sleep in time after the user's service is completed, resulting in high overall power consumption of the communication module. SUMMARY

[0004] The embodiments of the present application provide a PSM sleep method and related device, which can control the time when the communication module enters PSM sleep, to solve the problem of user service execution failure or high power consumption of the communication module caused by the mismatch between the user service execution time and the 3324 timer time.

[0008] In the embodiments of the present application, a PSM hibernation method is provided. The first communication device sends first information to the controller when the service execution is completed, and receives second information from the controller through a first general purpose input output (GPIO) interface.

[0068] In order to make the purpose, technical solutions and advantages of the present application more clear, the present application will be described below in conjunction with the drawings in the present application.

[0069] The terms "first" and "second" and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. Furthermore, the terms "comprises", "comprising", "includes", "including", "has", "having" and the like are intended to cover a non-exclusive inclusion, such that a process, method, article, system or apparatus that comprises, includes or has a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, system or apparatus. Additionally, the terms "a" and "an" are defined as taking the meaning of "one or more" of the referenced item.

[0070] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase "in an embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of one another. It is appreciated that those skilled in the art can readily interpret implementation of the various embodiments in light of the disclosure and the inherent nature of the technical features, and that the technical features in different embodiments can be combined to form new embodiments according to their inherent logical relationships.

[0071] It should be understood that, in the application, "at least one" means one or more, "multiple" means two or more, "at least two" means two or three and three or more, and "and / or" is used to describe the relationship between associated objects, indicating that there can be three relationships, for example, "A and / or B" can mean that there are three cases of only A, only B, and A and B at the same time, where A and B can be singular or plural. The character " / " generally represents an "or" relationship between the associated objects before and after it. "At least one of the following" or similar expressions means any combination of these items, including any combination of single or multiple items. For example, at least one of a, b or c can mean a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, and c can be single or multiple.

[0072] It should be noted that in the present application, "indication" can include direct indication, indirect indication, explicit indication, and implicit indication. When describing certain indication information for indicating A, it can be understood that the indication information carries A, directly indicates A, or indirectly indicates A.

[0073] In the present application, the information indicated by the indication information is referred to as to-be-indicated information. In the implementation process, there are many ways to indicate the to-be-indicated information, for example, but not limited to, the to-be-indicated information can be directly indicated, such as the to-be-indicated information itself or the index of the to-be-indicated information. The to-be-indicated information can also be indirectly indicated by indicating other information, wherein the other information and the to-be-indicated information have an association relationship. The to-be-indicated information can also be only indicated a part of the to-be-indicated information, and the other part of the to-be-indicated information is known or agreed in advance. For example, the indication of specific information can also be achieved by means of the arrangement order of each information agreed in advance (for example, the protocol stipulates), thereby reducing the indication overhead to a certain extent. The to-be-indicated information can be sent as a whole, or can be sent separately into multiple sub-information, and the sending period and / or sending occasion of the sub-information can be the same or different. The specific sending method is not limited in the present application. The sending period and / or sending occasion of the sub-information can be predefined, for example, predefined according to the protocol, or configured by the transmitting end device by sending configuration information to the receiving end device.

[0074] It should be noted that in the present application, "sending" can be understood as "output", and "receiving" can be understood as "input". "Sending information to A", wherein "to A" only indicates the direction of information transmission, and A is the destination, without limiting that "sending information to A" must be direct sending on the air interface. "Sending information to A" includes directly sending information to A, and also includes indirectly sending information to A through a transmitter, so "sending information to A" can also be understood as "outputting information to A". Similarly, "receiving information from A" indicates that the source of the information is A, which includes directly receiving information from A, and also includes indirectly receiving information from A through a receiver, so "receiving information from A" can also be understood as "inputting information from A".

[0075] The present application provides a PSM hibernation method, which is applied to the field of communication technology, such as PSM hibernation of a communication module. In order to more clearly describe the scheme of the present application, some knowledge related to PSM hibernation of a communication module is introduced first.

[0076] Cat-1 module: Cat-1 is a standard of user terminal category under the 4th generation (4G) mobile communication long term evolution (LTE) network. The Cat-1 module has the characteristics of low delay, low cost and good mobility, and can support a terminal downlink rate of up to 10 Mbps, so as to enable the internet of things (IoT) devices to be connected to the LTE network with lower power consumption and lower cost. It is mainly applied to medium-speed cellular communication services, including but not limited to vehicle positioning, wearable devices, shared devices, video monitoring, financial payment, public talk and power centralized meter reading and other fields.

[0077] Low power mode PSM: that is, power saving mode, is a feature introduced by the 3rd generation partnership project (3GPP) R12, which is optimized for small data transmission scenarios and signaling overhead control. PSM is specially applied to low-speed internet access technologies such as NB-IoT / eMTC, which allows idle devices to be placed in low power mode to maximize energy savings when the internet of things device is not in use. Generally, the power consumption cost of the device when sleeping is completely disconnected from the network, and the power consumption cost of the device when waking up is reconnected. Therefore, LTE allows devices to remain connected to the network during sleep, and periodically wakes up the device in response, and then the device will sleep again until it receives the next wake-up to send data. This intermittent sending or receiving of data only consumes a small amount of energy, but throughout the life cycle of the device, it can minimize power consumption and maximize battery life.

[0078] Currently, after the PSM function of the communication module (such as Cat1 module) is turned on, it usually enters the idle state and waits for the 3324 timer to expire before entering PSM sleep. There are several ways to wake up the communication module, usually by pulling down the PSM_INT pin to wake up the communication module, or actively waking up the communication module by pressing the power key, or the network side wakes up the communication module through the tracking area update (TAU) timer.

[0079] The user can control the PSM sleep to wake up at any time by operating the PSM_INT pin or the power key, but cannot control the time when the communication module enters PSM sleep. In the case that the user's business of the communication module has not been completed, but the 3324 timer has expired, the communication module will enter PSM sleep, resulting in user business failure. If the 3324 timer time is lengthened, the communication module cannot enter PSM sleep in time after the user's business is completed, resulting in the overall power consumption of the communication module being improved.

[0080] In view of the technical problems of service execution failure or high power consumption of the communication module caused by the mismatch between the service execution time and the time of the 3324 timer, the embodiment of the present application provides an architecture of a communication system, and based on the architecture of the communication system, a PSM sleep method is correspondingly provided, which controls the time when the communication module enters the PSM sleep state through a GPIO interface, so as to solve the problem of service execution failure or high power consumption of the first communication device caused by the mismatch between the service execution time and the time of the 3324 timer, that is, to ensure the integrity of the communication module service and also make the communication module enter the PSM sleep in time, thereby reducing the power consumption of the communication module.

[0081] The embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0082] Please refer to Figure 1 , Figure 1 The architecture of the communication system provided in the embodiments of the present application is shown in the following figure.

[0083] As Figure 1 shown, the communication system includes an MCU and a communication module, which can be the Cat-1 module mentioned above, and the embodiments of the present application do not limit this.

[0084] Optionally, the communication module and the MCU can communicate through a universal asynchronous receiver / transmitter (UART).

[0085] The MCU wakes up the communication module by pulling down the PSM_INT pin, and when the communication module is woken up and executes the service, it first closes the PSM function and initializes the interrupt function of one of the GPIO interfaces, and keeps the interrupt function disabled, and the interrupt function is used to open the PSM function.

[0086] After the communication module completes the service execution, the interrupt function of the GPIO interface is enabled, and a status code is reported to the MCU through the UART to inform the MCU that the service execution is completed. After receiving the status code, the MCU can pull down the GPIO pin to trigger the interrupt function of the GPIO pin if there is no other service to be executed.

[0087] After the communication module receives the GPIO interrupt function trigger, the PSM function is enabled, and the 3324 timer time can also be set to be the minimum to ensure that the communication module can quickly enter the PSM after the service execution is completed, which can not only ensure the lowest power consumption of the communication module, but also ensure the normal execution of the service.

[0088] Please refer to Figure 2 , Figure 2A flowchart of a PSM hibernation method provided by the embodiment of the application is shown in the figure. The PSM hibernation method is applied to the field of communication technology, such as the PSM hibernation of a communication module. The PSM hibernation method includes but is not limited to the following steps.

[0089] S201: The first communication device sends first information to the controller when the service execution is completed. Correspondingly, the controller receives the first information from the first communication device.

[0090] S202: The controller sends second information to the first communication device through a first general-purpose input-output (GPIO) interface. Correspondingly, the first communication device receives the second information from the controller through the first GPIO interface.

Optionally, the first communication device can be specifically a communication module in the above Figure 1 , which is used to execute the PSM hibernation method in the embodiment of the application to control the time when the communication module enters the PSM hibernation, thereby solving the problem of user service execution failure or high power consumption of the communication module caused by the mismatch between the user service execution time and the time of the 3324 timer.

[0093] Optionally, the first information can be specifically a status code, which is used to indicate the completion of service execution of the first communication device.

[0094] In the embodiment of the application, the second information is sent to pull down the first GPIO interface pin, which is used to indicate that the first communication device enters the low-power mode PSM hibernation state.

[0095] By the embodiment of the present application, the time for the first communication device to enter the PSM sleep state can be controlled through the GPIO interface, so as to solve the problem of the service execution failure or the high power consumption of the first communication device caused by the mismatch between the service execution time and the time of the 3324 timer, that is, to ensure the integrity of the service of the first communication device and also make the first communication device enter the PSM sleep state in time.

[0096] In a possible embodiment, before the first communication device sends the first information to the controller, the first communication device also enables the interrupt function of the first GPIO interface.

[0097] The interrupt function is used to open the PSM function.

[0098] It can be understood that the interrupt function is in the disabled state at this time, and the received second information is used to trigger the interrupt function to make the interrupt function enter the working state.

[0099] By the embodiment of the present application, the time for the first communication device to enter the PSM sleep state can be controlled through the first GPIO interface by enabling the interrupt function of the first GPIO interface, so as to solve the problem of the service execution failure or the high power consumption of the first communication device caused by the mismatch between the service execution time and the time of the 3324 timer.

[0100] In a possible embodiment, after the first communication device receives the second information from the controller through the first general-purpose input / output (GPIO) interface, the first communication device opens the PSM function, and the time of the first timer can also be set as the minimum value in the value range.

[0101] Optionally, the first timer in the embodiment of the present application is used to set the time for waiting in the idle state before entering the PSM, which can be the 3324 timer.

[0102] By the embodiment of the present application, the integrity of the service of the first communication device can be ensured, and the first communication device also enters the PSM sleep state in time, thereby reducing the power consumption of the first communication device.

[0105] When the communication module is woken up to perform a service, the PSM function is first closed, and the GPIO interrupt is initialized, that is, an interrupt function is initialized for one of the GPIO interfaces, and the interrupt function is kept in a disabled state. The interrupt function is used to open the PSM function.

[0106] After the service of the communication module is completed, the interrupt function of the GPIO interface is enabled, and a status code is reported to the MCU through the UART to inform the MCU that the service is completed.

[0107] After the MCU receives the status code, if there is no other service to be executed, the MCU can pull down the GPIO pin to trigger the interrupt function of the GPIO pin.

[0108] After the communication module receives the GPIO interrupt function trigger, the PSM function is enabled, and the 3324 timer time can also be set to be the minimum to ensure that the communication module can quickly enter the PSM after the service of the communication module is completed, which can ensure that the power consumption of the communication module is the lowest, and also ensure that the service is normally completed.
