Detailed Description
As described in the background, when bluetooth and WiFi P2P coexist and bluetooth connection and file transfer between two terminal devices sharing RF between bluetooth and P2P are performed, a situation in which one terminal device P2P does not associate with another terminal device or data transfer failure occurs while associating with another terminal device often occurs.
The researchers of this application found that in the implementation scheme of sharing RF between bluetooth and P2P, RF is distributed in a fixed period, and each terminal switches RF according to its own timing sequence, although the RF distribution period of two terminals is the same, the time slices for distributing bluetooth and P2P are the same, and the sequence for distributing RF to bluetooth and P2P is the same, the switching timing sequences of RF of two terminals are different, and it is the problem that P2P is not associated or data transmission fails in P2P association due to the different switching timing sequences of RF of two terminals.
Referring to fig. 1, fig. 1 is a schematic diagram of an RF switching timing sequence of two terminals with bluetooth and WiFi P2P coexisting in the prior art, in fig. 1, bluetooth refers to a bluetooth time slice, P2P refers to a P2P time slice, and both terminals adopt the same RF distribution manner: the time slices allocated to bluetooth by RF and the time slices of P2P total 50ms, so the fixed period of RF allocation is 50ms, the bluetooth time slices and the P2P time slices are both 25ms, and the fixed sequence of allocation is bluetooth first and P2P second.
However, the two terminals schedule the RF randomly, which means that the starting time of the RF scheduling is random, when BT and P2P coexist, the starting time of the RF scheduling is two states of entering a P2P working state or exiting a P2P sleep state, the two states have difference in the two terminals, which results in the random starting time of the RF scheduling, the subsequent RF scheduling timing is inconsistent, and the bluetooth and P2P coexist and adopt a CTS-to-self protection mechanism, when the RF is switched to P2P, P2P does not care whether the opposite terminal RF is switched to P2P to start to transmit the data packet, which results in a large amount of data transmission failure. It should be noted that the CTS-to-self protection mechanism can be understood by those skilled in the art, and will not be described in detail.
The embodiment of the invention provides a technical scheme, which enables the RF switching time sequences of different terminals transmitting data by Bluetooth to be the same, and the technical scheme is that when the Bluetooth connection is established and WiFi P2P is not associated, RF scheduling is carried out according to set time slice distribution based on the operation clock of a Bluetooth master device, so that the RF switching time sequences of the terminals and other terminals establishing Bluetooth with the terminals are synchronous, when WiFi P2P is associated, RF scheduling is carried out according to the set time slice distribution based on the operation clock of a P2P master device, so that the RF switching time sequences of the terminals and other terminals coupled with the terminals and coexisting with the Bluetooth and the P2P are consistent, and normal P2P association and data transmission can be carried out between the terminals and the other terminals.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Fig. 2 is a flowchart of a communication method for coexistence of bluetooth and WiFi P2P in an embodiment of the present invention.
Referring to fig. 2, the bluetooth and P2P coexisting communication method may include the following steps:
step S201: when a bluetooth connection is established and the WiFi P2P is not associated, the running clock of the bluetooth master device is acquired.
When the terminal equipment establishes Bluetooth connection with other terminal equipment, the Bluetooth equipment forms a Picnet (PICONET), and the main clock of the Picnet is the actual operation clock of the Bluetooth main equipment.
In a specific implementation, before acquiring the running clock of the bluetooth master device, the terminal device and the other terminals are transmitting data using bluetooth.
Step S202: and performing RF scheduling according to set time slice distribution between the Bluetooth and the WiFi P2P based on the running clock of the Bluetooth master device so as to synchronize the RF switching time sequence of the terminal and other terminals coupled with the terminal.
In a specific implementation, a modulus operation may be performed on the operation clock of the bluetooth master device, where a divisor is an RF distribution period, and when a result obtained by the modulus operation is 0, RF scheduling is performed according to the set time slice distribution.
For example, the first terminal device and the second terminal device are using bluetooth to transmit data, and P2P of the first terminal device and the second terminal device are not related, and the allocation period of RF is 25ms for both bluetooth and P2P, so that the first terminal device and the second terminal device perform modulo 50 operation on the running clock of the bluetooth master device, and perform RF scheduling according to the allocation of the set slots, i.e., 25ms for bluetooth slot and 25ms for P2P slot, at the time when the modulo operation result is 0, so that the RF scheduling timings of the first terminal device and the second terminal device are the same, as shown in fig. 3, where bluetooth is a bluetooth slot, and P2P is a P2P slot.
Step S203: when the WiFi P2P has been associated, the running clock of the WiFi P2P master device is acquired.
In a specific implementation, before P2P association, each terminal device operates according to a respective Timing Synchronization Function (TSF) clock, and when P2P is associated, acquires the TSF clock of a P2P master device, where the P2P master device is referred to herein as the role go (group owner) of P2P.
Step S204: and performing RF scheduling between the Bluetooth and the WiFi P2P according to set time slice distribution based on the running clock of the WiFi P2P master device so as to enable the RF switching time sequence of the terminal and other terminals coupled with the terminal to be consistent.
In particular implementations, to ensure that beacon (beacon) frames are received at the TBTT time, the TSF of P2P needs to be reused for synchronization.
In a specific implementation, a Beacon frame Transmission Time (TBTT) may be determined based on the TSF clock of the WiFi P2P master device, and according to the Beacon frame Transmission Time, RF scheduling is performed between bluetooth and WiFi P2P according to the set Time slice allocation, where the set Time slice allocation specifically allocates bluetooth and P2P Time slices, and may be set as needed, and the TBTT Time is a Time when the TSF clock of the WiFi P2P master device modulo a Beacon frame Transmission/reception Time interval to zero.
In a specific implementation, to further ensure that the beacon frame is received, the timing of synchronizing P2P may be advanced, so that the synchronization timing is advanced with respect to the transceiving timing of the beacon frame. Specifically, a fixed time may be preset, where the fixed time is greater than or equal to the switching time between bluetooth and P2P, and it is determined whether the current time is separated from the next beacon frame receiving/transmitting time by the fixed time, and when the current time is separated from the next beacon frame receiving/transmitting time by the fixed time, RF scheduling is performed according to the set time slice allocation.
In a specific implementation, the set time slice allocation may be determined as follows: dividing the RF use time into a Bluetooth time slice and a WiFi P2P time slice in a time division multiplexing mode in the RF distribution period, wherein the Bluetooth time slice is continuous with the WiFi P2P time slice.
For example, the allocation period of the RF is 50ms, and the usage time of the RF is divided into bluetooth time slices and WiFi P2P time slices in a time division multiplexing manner within 50 ms.
In the embodiment, when the bluetooth connection is established and the WiFi P2P is not associated, the RF scheduling is performed according to the set time slice allocation based on the operation clock of the bluetooth master device, so that the RF switching timings of the terminal and other terminals with which the bluetooth is established are synchronized, and when the WiFi P2P is associated, the RF scheduling is performed according to the set time slice allocation based on the operation clock of the WiFi P2P master device, so that the RF switching timings of the terminal and other terminals with which the bluetooth and WiFi P2P coupled coexist are consistent, and thus the normal WiFi P2P association and data transmission can be performed between the terminal and other terminals.
