In order to solve the technical problems, the general idea of the embodiment of the present application is as follows:

In order to better understand the technical solutions, the technical solutions of the present invention are described in detail below with reference to the drawings and specific embodiments, and it should be understood that the specific features in the embodiments and examples of the present invention are detailed descriptions of the technical solutions of the present invention, and are not limitations of the technical solutions of the present invention, and the technical features in the embodiments and examples of the present invention may be combined with each other without conflict.
Example one
Referring to fig. 1, the present application provides an information processing method applied to an electronic device, the method including:
s10: receiving, by a wireless communication module of the electronic device, frame information;
s20: acquiring related information of the frame information;
s30: judging whether the related information is matched with a preset filtering condition;
s40: and when the relevant information is not matched with the preset filtering condition, controlling a processor in the electronic equipment to process the frame information.
In a specific implementation process, the electronic device may be a mobile phone, a tablet computer, or other electronic devices including a wireless communication module, which is not necessarily exemplified herein. In the embodiment of the present application, an implementation process of the method in the embodiment of the present application will be described in detail by taking the electronic device as a mobile phone as an example.
Specifically, the mobile phone in the embodiment of the present application is provided with a wireless Communication module, such as a bluetooth module, an NFC (Near Field Communication) module, an infrared module, and the like, and in the embodiment of the present application, an implementation process of the method in the embodiment of the present application will be described with the wireless Communication module as the bluetooth module.
Further, the electronic device is further provided with a processor configured to process frame information received by the wireless communication module, where the processor specifically includes a first state and a second state, and first power consumption of the processor in the first state is smaller than second power consumption of the processor in the second state. Generally, when the processor does not receive the frame information, the processor is in a first state, such as a low power state, e.g., a sleep state, and when the processor receives the frame information, the processor is in a second state, i.e., an active state.
In the embodiment of the present application, step S10 is first executed: receiving, by a wireless communication module of the electronic device, frame information. For example, when the bluetooth module is arranged in the mobile phone, the frame information sent by other bluetooth devices can be received.
Next, step S20 is executed: and acquiring related information of the frame information. The specific implementation process is as follows:
and acquiring a first field in the header information of the frame information and acquiring a second field in the load information of the frame information.
Specifically, still taking the above mobile phone with bluetooth module as an example, in the bluetooth transmission protocol, a Data PDU and a Control PDU may be transmitted between bluetooth devices, and in this embodiment, taking filtering Control frame information as an example, the structure of the Control frame includes a header portion (header) and a payload portion (payload), where both the header portion and the payload portion have respective lengths, for example, the header portion is two bytes.
When a bluetooth module of a mobile phone receives frame information, a first field in packet header information of the frame information is obtained, where the first field may be first byte information of a packet header, and if the packet header information is 00010011, the first field corresponds to the first byte 0001; a second field in the payload information of the frame information is obtained, for example, when the payload information is 1001011010100101 …, the second field may be 10010110, which is a first byte of the payload information.
Next, step S30 is executed: and judging whether the related information is matched with a preset filtering condition.
In a specific implementation process, a filter is arranged in the mobile phone, and before frame information is filtered, a filtering condition of the filter can be configured in advance, wherein the preset filtering condition comprises N filtering sub-items, and each filtering sub-item in the N filtering sub-items comprises a category field and an operation code field; n is a positive integer.
Specifically, the bluetooth low energy device transmits information through two channels during communication, one is an advertisement channel, the other is a data channel, if a user wants to filter frame information transmitted from some categories of advertisement channels, such as advertisement channel frame information with a category field of 0101, 0101 is written into a filtering sub-item, if data channel frame information with an operation code field of 1011 is to be filtered, 1011 is written into the filtering sub-item, that is, the category field in the filtering sub-item is specially used for filtering the frame information of the advertisement channel, the operation code field is specially used for filtering the frame information of the data channel, since the filter comprises a plurality of filtering sub-items, each filtering sub-item can be written into a category field and an operation code field, when there are a plurality of frame information to be filtered, the category field or the operation code field corresponding to the frame information can be written into a plurality of filtering sub-items, the number of the filtering sub-items is determined by the maximum number of the frame information types needing to be filtered from the advertising channel and the data channel, for example, the number of the frame information types needing to be filtered from the advertising channel is 5, corresponding category fields need to be written in the 5 filtering sub-items, the number of the frame information types needing to be filtered from the data channel is 6, and corresponding operation code fields need to be written in the 6 filtering sub-items, so that the total number of the filtering sub-items contained in the filter is 6, wherein the category fields and the operation code fields are written in the 5 filtering sub-items, and 1 filtering sub-item is only written in the operation code field.
Next, step 30 is performed: and judging whether the frame information is matched with a preset filtering condition. Referring to fig. 2, the specific implementation process of step S30 is as follows:
s301: determining whether the first field or the second field matches M of the N filter sub-entries; m is an integer of 1 to N.
Step S301 further includes the following steps:
s3011: when the transmission channel of the frame information is determined to be an advertisement channel, judging whether the first field is matched with any one of M category fields corresponding to the M filtering sub items, and obtaining M first judgment results; judging whether the first field is matched with the M filtering sub-items or not based on the M first judgment results; or
S3012: when the transmission channel of the frame information is determined to be a data channel, judging whether the second field is matched with any one of M operation code fields corresponding to the M filtering sub items to obtain M second judgment results; determining whether the second field matches the M filter sub-entries based on the M second determination results.
For step S3011, the specific implementation is as follows:
judging whether the M first judgment results are all negative;
if yes, determining that the first field does not match the M filter sub-entries;
if not, determining that the first field is matched with the M filtering sub-items.
For step S3012, the specific implementation is as follows:
judging whether the M second judgment results are all negative;
if so, determining that the second field does not match the M filter sub-entries;
if not, determining that the second field is matched with the M filtering sub-items.
Specifically, when there are N filter sub-entries in the filter, for example, when N is 3, the maximum numerical values of the category field and the opcode field written in the filter sub-entry are all 3, and it is assumed that 2 category fields and 3 opcode fields are written in 3 filter sub-entries. When frame information received by the bluetooth module is received, it is first determined from which transmission channel the received frame information is coming from, the transmission channel information may be determined by the physical layer, if it is determined that the frame information is transmitted through the advertisement channel, the first byte of the header portion and the first byte of the payload portion of the frame information are obtained, assuming that the first byte of the header portion is 00010001 and the first byte of the payload portion is 00100010, the two bytes are sent to the filter to be matched with the filter sub-entry, since only the first byte of the header is required to be matched for the frame information of the advertisement channel, the first byte of the payload part is not required to be matched, it is also possible to take only the first byte of the header portion and send it to the filter, which, in the embodiment of the present application, in order to simplify the processing steps in a specific implementation, a method for acquiring a first field of a packet header and a second field of a payload is adopted uniformly.
Further, following the above example, when the first byte of the header portion of the frame information packet transmitted by the advertisement channel is 00010001, the byte is compared with the category fields in the 2 filtering sub-entries, at this time, the value of M is 2, if the preset 2 category fields are 00000001 and 00000010 respectively, and since the first byte of the header portion of the frame information is 00010001, which is different from the three category fields, it indicates that the frame information is valid frame information, that is, the first field does not match with the M filtering sub-entries, and needs to be sent to the processor for processing. If the preset 2 category fields are 00010001 and 00010010, since the first byte 00010001 of the header part of the frame packet is the same as one of the category fields, it indicates that the first field matches with the category field, and the frame information is an invalid frame or a useless frame that needs to be filtered out and does not need to be sent to the processor for processing.
Correspondingly, when the received frame information is transmitted by a data channel, the first byte of the header of the frame information and the first byte of the payload are also acquired, and the two bytes are sent to a filter for matching processing.
Still continuing with the above example, when there are 3 filtering sub-entries in the filter, and 2 category fields and 3 opcode fields are written in the 3 filtering sub-entries, at this time, the values of N and M are both 3, if the 3 opcode fields are 10001000, 10011001, and 10011010, respectively, the first byte of the frame information payload portion is 00100010, and the first byte and the 3 opcode fields are matched, respectively, it can be obtained that the first byte and the 3 opcode fields are not matched, that is, the second field is not matched with the M filtering sub-entries, indicating that the frame information is valid frame information, and needs to be sent to the processor for processing. If the 3 operation code fields are 00100010, 00100011 and 00100100100 respectively, since the first byte of the payload part is the same as one of the operation code fields, it indicates that the second field matches the operation code field, and the frame information is an invalid frame or a useless frame that needs to be filtered out and does not need to be sent to the processor for processing.
Further, each filter sub-item in the filter may include a valid bit, and when the value of the valid bit is the preset value, the filter sub-item corresponding to the valid bit is in an active state, so in this case, M filter sub-items whose value of the valid bit is a preset value need to be determined from the N filter sub-items, and then the step of determining whether the frame information matches a preset filter condition is performed.
Specifically, when the filter sub-entry contains a valid bit, each filter sub-entry contains a valid bit, a category field, and an operation code field, and whether the filter sub-entry is in a working state is determined by the valid bit, if the valid bit of one filter sub-entry is 1, the filter sub-entry is in the working state, and when frame information is received, a first field and a second field of the frame information are respectively matched with the category field and the operation code field of the filter sub-entry, that is, frame information of an advertisement channel type and a data channel type written in the filter sub-entry needs to be filtered; if the valid bit of a filter sub-entry is 0, it indicates that the filter sub-entry is in an inactive state, and when receiving frame information, the first field and the second field are not matched with the category field and the operation code field in the filter sub-entry, i.e. the frame information of the advertisement channel type and the data channel type written in the filter sub-entry is not required to be filtered.
Furthermore, when the filtering sub-items contain valid bits, a user can write all the category fields and the operation code fields of common types into the filtering sub-items, and when some types of frame information need to be filtered, the valid bits of the filtering sub-items corresponding to the types are defined as 1, namely preset values, so that the filtering sub-items are in a working state, the valid bits of the remaining filtering sub-items are defined as 0, namely the remaining filtering sub-items are in a non-working state, so that the situation that the user needs to set the operation code fields and the category fields every time according to different types of the filtered frame information is avoided, and the setting of the filter is more concise and convenient.
As described above, when the processor does not receive the frame information, the processor is in the first state, and if the frame information is received by the bluetooth module and does not match with the filtering condition of the filter at this time, the following steps are performed:
controlling the processor to switch from the first state to the second state;
and controlling the processor to process the frame information.
Specifically, when the processor is in a low power consumption state, if the frame information received by the bluetooth module is a valid frame at the moment, the processor is awakened, and the processor is switched to an operating state from the low power consumption state so as to process the frame information; when the processor is in the low power consumption state, if the frame information received by the Bluetooth module is an invalid frame, the processor is still in the low power consumption state, so that the power consumption of the processor is saved.
Further, when the frame information matches the preset filtering condition, the frame information is stored in a memory, or the frame information is discarded.
Specifically, when the first byte of the header part of the frame information of the advertisement channel matches with the category field in the filter sub-item, or the first byte of the payload part of the frame information of the data channel matches with the operation code field in the filter sub-item, it indicates that the frame information matches with the preset filter condition, that is, the frame information is an invalid frame or a useless frame, and the frame information can be discarded, but some invalid frames or useless frames may be related to subsequent debugging.
