Negotiation carrier wave is encapsulated into switching selection message and is sent to carrier switch request side.
The process emphasis is in the determination process for negotiating carrier wave, and there are mainly three types of processing modes：A modes：When carrier switch selects
When the optional carrier wave for the side of selecting is in idle state, final negotiation carrier wave by the optional carrier list in switching request message Lai
It determines.First carrier wave is to negotiate carrier wave in optional carrier wave selective listing, i.e., the conduct negotiation carrier wave of highest priority in list；
B modes：When the optional carrier wave of carrier switch request side is idle, and carrier switch selecting party only has the optional carrier wave in part and is using
In the case of, the idle carrier wave that switching request side and switching selecting party are supported disappears as carrier wave is negotiated according to switching request
The preferred sequence of optional carrier list is selected in breath；C modes：It obtains carrier switch selecting party and carrier switch request side is each
Optional carrier wave uses remaining time, is applied in addition to A by comparing carrier wave idle earliest is calculated as carrier wave, which is negotiated
Other application scene except the application scenarios of mode and B modes.Wherein, other than the application scenarios of A modes and B modes
In other application scene, there are a kind of situations to be：The carrier wave of carrier switch request side and carrier switch selecting party partly uses
The case where, at this time, it is preferable that first judge whether the carrier wave idle in both sides, and if it exists, then directly from idle carrier wave
Otherwise middle selection, then is selected using C modes.
Following table describes carrier wave of the carrier switch selecting party in one's own side and carrier switch request side and is in different conditions situation
Lower switching selection course needs the processing mode correspondence taken.
It being illustrated based on above-mentioned principle, the detailed process for carrying out carrier wave selection to carrier switch selecting party below illustrates,
As shown in fig. 7, comprises following steps：
Step S701 starts；
Step S702 is monitored and is received switching request message；
Step S703 parses switching request message and obtains each optional carrier wave current state in carrier switch request side, simultaneously
Obtain carrier switch selecting party currently optional Carrier State；
Step S704, judges whether the optional carrier wave of carrier switch selecting party is currently in idle state, if so, executing step
Rapid S705；Otherwise, step S706 is executed；
Step S705 turns step using first carrier wave in optional carrier list in switching request message as carrier wave is negotiated
Rapid S709；
Step S706 judges that carrier switch request can select whether carrier wave is currently in idle state and carrier switch selects
The side of selecting only has the optional carrier wave in part and is in use state, if so, executing step S707；Otherwise, step S708 is executed；
Step S707, compares carrier switch request side and idle carrier wave that carrier switch selecting party is supported is as negotiating to carry
Wave is selected according to the priority orders of optional carrier list in switching request message, goes to step S709；
Step S708, acquisition carrier switch selecting party and each optional carrier wave in carrier switch request side use remaining time,
By comparing idle carrier wave earliest is calculated S709 is gone to step as carrier wave is negotiated；
It illustrates：Assuming that switching request side supports two kinds of carrier technology of Wi-Fi and Bluetooth, remaining time is used
Respectively 13 seconds and 15 seconds；Switching selecting party similarly supports Wi-Fi and Bluetooth, the use of remaining time is respectively 10 seconds
With 20 seconds.Compare calculating by both sides, both sides Wi-Fi can just be in idle state in earliest 13 seconds, and Bluetooth is needed earliest
Want can just enter idle state within 20 seconds, then the idle remaining time of Wi-Fi is 13 seconds, the idle remaining time of Bluetooth
It is 20 seconds.Both therefore compare, select Wi-Fi can be relatively high as negotiation carrier wave efficiency.Therefore final choice Wi-Fi in the example
As final negotiation carrier wave.
Final negotiation carrier wave is encapsulated into switching selection message and is sent to carrier switch request side by step S709.
Step S710 terminates.
In conclusion the present embodiment the method increases when NFC carrier waves are negotiated to the currently used state of optional carrier wave
Negotiate, according to the combined situation of the optional carrier wave use state of communicating pair, select optimal optional carrier wave and carry out data transmission,
Data transmission efficiency is improved, the user experience is improved.
