Specific embodiment
As background technology is sayed, when bluetooth and WiFi P2P coexist, and bluetooth and P2P share RF's
When bluetooth connection and mutually transmission file are carried out between two station terminal equipment, an end is often occurred in which
End equipment P2P does not associate another station terminal equipment, or the upper another station terminal equipment of association but occurs number
According to the situation of bust this.
The application's it was discovered by researchers that in the implementation of the shared RF of bluetooth and P2P, with fixed week
Phase is allocated to RF, the switching of RF is all carried out according to the sequential of itself per station terminal, although two ends
The RF assignment periods at end are identical, and distribution bluetooth is identical with the timeslice of P2P, and RF is to bluetooth and P2P for distribution
Order it is also identical, but the switching sequence of the RF of two station terminals is different, just because of two station terminal RF
Switching sequence difference cause P2P do not associate or P2P associations on but data transmission fails problem.
Fig. 1 is refer to, Fig. 1 is the RF of two station terminals that a kind of bluetooth of the prior art and P2P coexist
Switching sequence schematic diagram, bluetooth refers to Bluetooth time piece in Fig. 1, and P2P refers to P2P timeslices, two station terminals
Use the identical RF methods of salary distribution：The timeslice of timeslice and P2P that RF distributes to bluetooth amounts to
50ms, therefore the fixed cycle of RF distribution is 50ms, Bluetooth time piece and P2P timeslices are 25ms,
The permanent order of distribution is P2P after first bluetooth.
But, two station terminals scheduling RF is random, refers at random that the initial time of RF scheduling is random,
When BT and P2P coexist, the initial time of RF scheduling is into P2P working conditions or exits P2P and stop
Two kinds of dormancy state, both states have differences in two station terminals, cause RF dispatch initial time with
Machine, subsequent RF scheduling sequential is inconsistent, and bluetooth is coexisted using CTS-to-self protections with P2P
Mechanism, when RF is switched to P2P, P2P will not be concerned about whether opposite end RF is switched to P2P and begins to hair
Packet is sent, so causes mass data to send failure.Herein it should be noted that people in the art
Member is it will be appreciated that CTS-to-self protection mechanisms, repeat no more.
The embodiment of the invention provides a kind of technical scheme so that with the difference of bluetooth data transmission eventually
The RF switching sequences at end are identical, and the technical scheme is by having set up in bluetooth connection and WiFi P2P are not closed
During connection, the operation clock based on bluetooth master carries out RF scheduling to be distributed by setting time piece so that institute
Terminal and synchronous with the RF switching sequences of the other-end that it sets up bluetooth is stated, when WiFi P2P have been closed
During connection, the operation clock based on P2P main equipments carries out RF scheduling by setting time piece distribution so that
The RF switching sequences one of the terminal device that the terminal and other coupled bluetooths and P2P coexist
Cause, so that normal P2P can be carried out between the terminal and other-end associating and data transfer.
It is understandable to enable the above objects, features and advantages of the present invention to become apparent, below in conjunction with the accompanying drawings

Between piece be assigned as specifically distributing bluetooth and P2P timeslices, can be set as needed, the TBTT
Moment be the WiFi P2P main equipments TSF clocks to beacon frame transmitting-receiving time interval modulus be zero when
Carve.
In specific implementation, beacon frames are received to further ensure that, the moment of synchronous P2P can be carried
Before so that synchronization point shifts to an earlier date the transmitting-receiving moment in beacon frames.Specifically, when can preset a fixation
Between, the set time, more than or equal to bluetooth and the switching time of P2P, judges current time under
One beacon frame transmit/receive the moment whether fixed time intervals, receive apart from next beacon frame when the current time/
Described in hair time at intervals during the set time, RF scheduling is carried out by setting time piece distribution.
In specific implementation, the setting time piece distribution can determine in the following way：In dividing for RF
With the use time of RF is divided into Bluetooth time piece and WiFi P2P in a time multiplexed manner in the cycle
Timeslice, the Bluetooth time piece continues with the WiFi P2P timeslices.
For example, the assignment period of RF is 50ms, time-multiplexed mode is by the use of RF in 50ms
Time is divided into Bluetooth time piece and WiFi P2P timeslices.
The present embodiment by when bluetooth connection has been set up and WiFi P2P are not associated, based on bluetooth master
Operation clock by the distribution of setting time piece carry out RF scheduling so that the terminal and set up indigo plant with it
The RF switching sequence synchronizations of the other-end of tooth, when WiFi P2P have been associated, based on WiFi P2P masters
The operation clock of equipment by the setting time piece distribution carry out RF scheduling so that the terminal and and its
Other bluetooths of coupling are consistent with the RF switching sequences of the terminal device that WiFi P2P coexist, so that institute
State and can be carried out between terminal and other-end normal WiFi P2P and associate and data transfer.
