Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a diagram illustrating a method for controlling chip acquisition and positioning according to an exemplary embodiment of the present disclosure, where the chip may include a chip based on narrowband internet of things communication, and the method may be applied to a dual-mode baseband processing chip that supports both narrowband internet of things communication and GPS positioning. As shown in fig. 1, the method includes steps 101 to 103.
In step 101, a positioning request is received. The positioning request may be a positioning request from a user, or a positioning request from another location, as long as the positioning request is a request for requesting positioning information.
In step 102, the positioning request is decomposed into positioning time slices. The method of splitting the request into time slices is well known to those skilled in the art, and for example, the TDD technology in the 3G field uses time slice division, so the method of splitting the request into time slices is not described herein again.
In step 103, when the narrowband internet of things communication state is an idle state and an idle interval in the narrowband internet of things communication is greater than or equal to a preset threshold, the positioning time slice is inserted into the idle interval in the narrowband internet of things communication to control the GPS data processing module to acquire the current positioning information.
The GPS data processing module may be, for example, a programmable processor or a digital logic circuit, and is capable of performing demodulation of GPS signals, C/a code acquisition, P code acquisition, tracking loop, and the like to acquire positioning signals.
The narrow-band internet of things communication state can be, for example, the state of a narrow-band internet of things communication module, and the narrow-band internet of things communication module can be, for example, a programmable processor or a digital logic circuit, and can complete receiving, demodulating, decoding and other works of a narrow-band internet of things signal so as to complete narrow-band internet of things communication. The narrowband internet of things communication state can be, for example, a standby state, an idle state, a connection state, and the like. When the narrowband internet of things communication state is an idle state, discontinuous receiving actions such as paging can be performed, the discontinuous receiving actions can be completed by the narrowband internet of things communication module, for example, the narrowband internet of things communication module is enabled to perform communication for time K at intervals of time T, wherein K < T, the length of time T is determined by setting of a base station side of the narrowband internet of things, and the value of time K is as short as possible in a range shorter than time T. The idle interval may be the time T, and the preset threshold is a self-defined time threshold, where the time threshold is used to ensure that the time T is sufficient for the GPS data processing module to complete one or part of the acquisition of the GPS positioning information. For example, when the narrowband internet-of-things communication module is enabled to perform communication at time K every time T, and when the time T is greater than or equal to the preset threshold, the positioning time slice is inserted into the idle interval T, the GPS data processing module is enabled to operate in the time period of the time T, and the narrowband internet-of-things communication module operates in the time period of the time K, which are alternated, so that the GPS positioning information can be acquired in the idle interval during which narrowband internet-of-things communication is performed.
In a possible implementation manner, the method further includes receiving a data transceiving request from a user, decomposing the data transceiving request into data transceiving time slices, and controlling a narrowband internet of things communication module to perform narrowband internet of things communication according to the data transceiving time slices.
According to the technical scheme, the positioning request is received in the chip supporting the narrow-band Internet of things communication, the positioning request is decomposed into the time slices which are inserted into the idle intervals in the narrow-band Internet of things communication to control the GPS data processing module to acquire the positioning information, the control method can enable the chip to carry out both the narrow-band Internet of things communication and the GPS positioning, the single chip Internet of things chip can support both the positioning and the narrow-band Internet of things communication, and because the GPS positioning and the narrow-band Internet of things communication can not be carried out simultaneously, the narrow-band Internet of things communication and the GPS positioning can use the same antenna and radio frequency transceiver, and the hardware cost is relatively saved.
In one possible embodiment, the method further comprises: and storing the current positioning information acquired by the GPS data processing module in a first database. The first database may be a memory space located on the chip. The GPS data processing module acquires the current positioning information and then stores the current positioning information in the first database, so that the first database can provide the latest positioning information as the current positioning information when the GPS data processing module cannot perform real-time positioning.
In one possible embodiment, the method further comprises: and identifying the credibility of the positioning information in the first database according to the switching record of the resident cell in the narrow-band Internet of things communication process. For example, the confidence level may be identified according to the number of times the camped cell has been switched after the positioning information is acquired, for example, if the camped cell has been switched 1 time after the positioning information is acquired, the confidence level is identified as level a, and if the camped cell has been switched 2 times after the positioning information is acquired, the confidence level is identified as level B; the confidence level may also be identified according to a range interval in which the number of times of the handover of the camping cell after the acquisition of the positioning information is located, for example, when the number of times of the handover of the camping cell after the acquisition of the positioning information is within 1 to 3, the confidence level is identified as a level a, and when the number of times of the handover of the camping cell after the acquisition of the positioning information is within 4 to 6, the confidence level is identified as a level B. This allows the identification to indicate the reliability of the location information when reporting on the basis of the location information stored in the first database.
In one possible embodiment, the method further comprises: and after the GPS data processing module finishes one or more times of acquisition of the positioning information according to the positioning request, setting the GPS positioning state to be a standby state. Because network interaction with the outside cannot be performed when the narrow-band internet of things is in sleep for a long time, reporting of GPS positioning information on a server or other nodes on the network is not needed, and the GPS data processing module only needs to acquire the current positioning information when receiving a positioning request of a user. The positioning request can be a single positioning request or a continuous positioning request, but no matter the positioning request is the single positioning request or the continuous positioning request, the GPS data processing module does not keep the starting state any more as long as the GPS data processing module finishes one or more times of acquisition of positioning information required by the positioning request in the idle interval of the narrow-band Internet of things communication, and thus the power consumption of the GPS data processing module can be saved.
In one possible embodiment, the method further comprises: and when a narrow-band Internet of things data receiving and sending request is received in the process of acquiring the current positioning information by the GPS data processing module, stopping the work of the GPS data processing module. In the chip positioning obtaining method provided by the disclosure, the priority of the narrowband internet of things communication is higher than that of the GPS positioning, and therefore, when the positioning request is received, it is necessary to determine whether the idle interval of the narrowband internet of things communication is sufficient for GPS positioning, and even if the idle interval meets a preset condition, for example, is greater than or equal to the preset threshold, the positioning time slice has been inserted into the idle interval to obtain the current positioning information, and as long as the data transceiving request of the narrowband internet of things communication is received at this time, the operation of the GPS data processing module is stopped at any time, and the data transceiving request of the current narrowband internet of things communication is preferentially processed. Just so can realize under the prerequisite that single chip thing networking chip supported location and narrowband thing networking communication simultaneously, can also guarantee that narrowband thing networking communication's function does not receive GPS locate function's influence, and because GPS location can not go on simultaneously with narrowband thing networking communication, can also make narrowband thing networking communication and GPS location use same antenna and radio frequency transceiver like this, practiced thrift the hardware cost relatively.
In one possible embodiment, the method further comprises: and when the process of acquiring the current positioning information by the GPS data processing module is stopped midway, storing the GPS capture data acquired by the GPS data processing module in a second database. The second database may be provided in the chip. The GPS acquisition data may include data such as the position, velocity, doppler shift, etc. of the satellites in view in the current sky. Since the priority of the narrowband internet of things communication is higher than that of the GPS positioning, a situation that the GPS positioning needs to be interrupted immediately to process a data transceiving request when the data transceiving request of the narrowband internet of things communication is received in the process of acquiring the current positioning information in the GPS positioning time slice. Therefore, in the process of acquiring the positioning information by the GPS data processing module, the acquired GPS capturing data is stored in the second database, so that the positioning and tracking can be quickly restored according to the GPS capturing data stored in the second database when the work of the GPS data processing module is started again after being interrupted, and the desynchronization of the GPS positioning is reduced to a certain extent.
Fig. 2 is a diagram illustrating a method for controlling chip acquisition positioning according to yet another exemplary embodiment of the present disclosure. As shown in fig. 2, the method includes steps 201 to 206 in addition to steps 101 and 102 shown in fig. 1.
In step 201, it is determined whether the narrowband internet of things communication state is an idle state, if so, the process goes to step 203, and if not, the process goes to step 202.
In step 202, the latest positioning information in the first database is used as the current positioning information. When the communication state of the narrowband internet of things is in a non-idle state, namely the communication state of the narrowband internet of things is in a standby state or a connection state and the like, the GPS data processing module is not controlled to carry out GPS positioning, and the latest positioning information in the first database is used as the current positioning information. Therefore, the current positioning information reported when the narrow-band internet of things is communicated for data interaction is the latest positioning information in the first database.
In step 203, it is determined whether an idle interval in the narrowband internet of things communication is greater than or equal to a preset threshold, if so, the process goes to step 204, and if not, the process goes to step 202. The idle interval in the narrowband internet of things communication is a time interval in which the positioning time slice can be inserted, the preset threshold is used for ensuring that the time T is enough for the GPS data processing module to finish one-time or partial GPS positioning information acquisition, and the preset threshold is a self-defined time threshold and is not limited by a specific numerical value. If the idle interval in the narrowband internet of things communication is judged to be smaller than the preset threshold, it indicates that the positioning time slice cannot be inserted into the current narrowband internet of things communication, that is, the GPS positioning information cannot be acquired, so step 202 is executed to use the latest positioning information in the first database as the current positioning information.
In step 204, it is determined whether there is GPS capture data in the second database that meets a predetermined condition. If yes, go to step 206, if not, go to step 205. The preset condition may be, for example, that the acquisition time is within a preset time, for example, GPS acquisition data whose acquisition time is within two hours.
In step 205, the positioning time slice is inserted into an idle interval in the narrowband internet of things communication to control the GPS data processing module to acquire the current positioning information. When the second database does not have available GPS capture data, the positioning time slice is directly inserted into an idle interval in the narrow-band Internet of things communication so as to control the GPS data processing module to acquire the current positioning information.
In step 206, the positioning time slice is inserted into an idle interval in the narrowband internet of things communication to control the GPS data processing module to acquire the current positioning information according to the GPS capture data in the second database. When available GPS capture data exists in the second database, the positioning time slice is inserted into an idle interval in the narrow-band Internet of things communication to control the GPS data processing module to acquire current positioning information according to the GPS capture data in the second database, and the GPS data processing module can recover positioning and tracking more quickly when the GPS data processing module starts to work again through the GPS capture data in the second database, so that the step-out of GPS positioning is reduced to a certain extent.
Through the technical scheme, when the idle interval of narrow-band internet of things communication is not enough to meet the requirement of obtaining the GPS positioning time, the last positioning information stored in the first database is used as the current positioning information, so that the problem that the positioning information cannot be reported after a user sends a positioning request is solved, and after the work of the GPS data processing module is interrupted, the work is started again, the positioning and tracking can be quickly restored again according to the GPS capturing data which is stored in the second database and meets the preset condition, so that the desynchronization of the GPS positioning is reduced to a certain extent. In addition, the narrow-band Internet of things communication module is aligned with the working time of the GPS data processing module, so that the time of the GPS in a tracking state for a long time can be reduced, and compared with the independent GPS module, the CPS data processing module is lower in power consumption. The control method can enable the chip to carry out GPS positioning in the idle interval during narrow-band Internet of things communication, not only realizes that the single chip Internet of things chip supports positioning and can also carry out narrow-band Internet of things communication, but also avoids the situation that the narrow-band Internet of things communication and the GPS positioning are carried out simultaneously because the GPS positioning is finished in the idle interval during the narrow-band Internet of things communication, thereby greatly reducing the peak value requirement of storage resources, reducing the area requirement and the power consumption of storage space in the chip, enabling the narrow-band Internet of things communication and the GPS positioning to use the same antenna and radio frequency transceiver, and relatively saving the hardware cost.
