Description of drawings
The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the communication terminal structural representation according to one embodiment of the invention;
Fig. 2 is the detailed structure schematic diagram according to the communication terminal shown in Figure 1 of one embodiment of the invention.
Embodiment
Fig. 1 is communication terminal 100 structural representations according to one embodiment of the invention.Communication terminal 100 comprises: the WiFi communication module 101 that is used to receive and dispatch and handle the WiFi signal; Be used to receive and dispatch and handle the WDCT communication module 102 of WDCT signal; Be used to eliminate the coexistence processing module 103 that frequency range is conflicted between WiFi communication module 101 and the WDCT communication module 102; Wherein, coexistence processing module 103 communicates to connect with WiFi communication module 101, WDCT communication module 102.
Be integrated with WIFI communication module 101 and WDCT communication module 102 in the communication terminal 100, WIFI communication module 101 can with WIFI terminal equipment notebook radio communication for example.WDCT communication module 102 can with the various terminal equipments of supporting WDCT for example the WDCT mobile phone wireless communicate by letter.
In an embodiment of the present invention, WiFi communication module 101 comprises that being used to send frequency range uses the frequency range of information to use information transmitting unit 101a; Coexistence processing module 103 comprises being used to receive from the frequency range of WiFi communication module 101 to be used information and is sent to the first processing unit 103a of WDCT communication module 102; WDCT communication module 102 comprises according to the frequency range that is received from coexistence processing module 103 to be used information and selects for use the frequency range of the frequency range different with described frequency range use information to select unit 102a for use.As shown in Figure 2.
WiFi and WDCT use the 2.4GHz frequency range, for fear of producing band interference between the two, influence proper communication, and WDCT can avoid the current use frequency range of WiFi.After communication terminal 100 powers on, WiFi communication module 101 will send its current use frequency range to WDCT communication module 102, and/or when WiFi communication module 101 changes current use frequency range, the new use frequency range that transmits after changing from trend WDCT communication module 102.After WDCT communication module 102 was learnt the use frequency range of WiFi communication module 101, the frequency range that the signal post between WDCT communication module 102 and the WDCT terminal equipment adopts can be avoided the use frequency range of WiFi communication module 101.
In order to solve the frequency range conflict between the two and the problem of Communication Jamming better, in an embodiment of the present invention, also can adopt the principle of WDCT priority communication.Because WIFI communication module 101 does not need real time communication with the WIFI terminal equipment, and WDCT communication module 102 needs real time communication with the WDCT terminal equipment, so can consider to communicate by letter simultaneously and produce interference when conflicting when the two, can allow WDCT preferential.
Can select the WDCT communication module only when receiving, to handle, also can select the WDCT communication module only when emission, to handle.
As shown in Figure 2, WDCT communication module 102 also comprises the request unit 102b that is used for sending to coexistence processing module 103 request signal when needs receive and/or send the WDCT signal; This request signal is used to ask WiFi communication module 101 to reduce or suspend reception and/or sends the WiFi signal.Coexistence processing module 103 also comprises and is used to receive from the request signal of described request unit and is sent to the second processing unit 103b of WiFi communication module.WiFi communication module 102 also comprises the requesting processing 101b that reduces or suspend reception and/or transmission WiFi signal according to the solicited message that is received from the second processing unit 103b.The second processing unit 103b and request unit 102b, requesting processing 101b communicate to connect.
In further embodiment of this invention, can also adopt feedback mechanism, also promptly request signal is responded.To this, the request unit 102b of WDCT communication module 102 sends the response that will wait for WiFi communication module 101 behind the request signal.When request unit 102b waits for the request feedback signal of described request processing unit and do not receive request feedback signal from the described request processing unit in Preset Time, send request signal to described coexistence processing module again.
Requesting processing 101b also is used for sending the request feedback signal so that will ask result to feed back to WDCT communication module 102.The second processing unit 103b also is used for receiving and transmits the described request feedback signal to request unit 102b.
The requesting processing 101b of WiFi communication module 102 also is used for recovering the operate as normal of WiFi communication module 102 after receiving the described request restoring signal, and recovers feedback signal by second processing unit 103b transmission and recovered operate as normal so that inform request unit 102b.
Process to the realization WDCT priority communication of communication terminal shown in Figure 2 is described in detail below, following (only being treated to example with WDCT communication module 102 when receiving describes):
1, when WDCT communication module 102 need receive the information of WDCT mobile phone for example, WDCT communication module 102 sends " request a-signal " to WIFI communication module 101, and request WIFI communication module 101 reduces emission or suspends emission.
If the use feedback signal, then WDCT communication module 102 can be waited for " the feedback a-signal " of WIFI communication module 101, if do not receive " feedback a-signal " for a long time, then WDCT communication module 102 repeats to send " request a-signal " to WIFI communication module 101.
2, after WIFI communication module 101 receives WDCT communication module 102 " request a-signal ", then reduce emission or suspend emission.
If the use feedback signal, then WIFI communication module 101 can transmit " feedback a-signal " more than 102 time to the WDCT communication module, informs that it receives " request a-signal " and reduced emission or suspend and launched.
If 3 use feedback signal, after WDCT communication module 102 is waited for " feedback a-signal " success of WIFI communication module 101, then receive the information of WDCT mobile phone.
When WDCT communication module 102 received the end of message of WDCT mobile phone, WDCT communication module 102 sent " request B signal " to WIFI communication module 101, and request WIFI communication module 101 is recovered normal transmission.
If 4 use feedback signal, then WDCT communication module 102 is waited for " the feedback B signal " of WIFI communication module 101, if do not receive " feedback B signal " for a long time, then WDCT communication module 102 repeats to send " request B signal " to WIFI communication module 101.
5, after WIFI communication module 101 receives WDCT communication module 102 " request B signal ", then recover normal transmission.
If the use feedback signal, then WIFI communication module 101 transmits " feedback B signal " to WDCT communication module more than 102 time, informs that it receives " request B signal " and recovered normal transmission.
If 6 use feedback signal, after then WDCT communication module 102 was waited for " feedback B signal " success of WIFI communication module 101, processing procedure finished.
Be understandable that, only show the unit relevant with interference about WIFI communication module 101 and WDCT communication module 102 among Fig. 2 with frequency range conflict of the present invention, and other functional units that communication is communicated by letter with WDCT about realization WIFI are all not shown, but this is not as limitation of the present invention.
