Detailed description of the invention

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the premise not making creative work, broadly fall into the scope of protection of the invention.

It should be noted that when not conflicting, the embodiment in the present invention and the feature in embodiment can be mutually combined.

Below in conjunction with the drawings and specific embodiments, the invention will be further described, but not as limiting to the invention.

As it is shown in figure 1, for dual network pattern coexisting structure of the prior art:

RF (RadioFrequency) in Fig. 1 represents radio-frequency receiving-transmitting layer；PHY (PhysicalLayer) represents physical layer；MAC1 and MAC2 represents the different media access control layer (MediumAccessControl) of application under two network schemers respectively；First communication protocol processes and the communication protocol treatment mechanism under second communication protocol processes respectively corresponding two network schemers, and MMI (Man-MachineInterface) represents man-machine interface.Then as it is shown in figure 1, mobile terminal shares a set of transceiver (RF and PHY) under two network schemers.Therefore, if dual network pattern coexist under any one network schemer under there is the application that network delay or network jitter is sensitive, then when carrying out OBSS scanning, the application of another network schemer will certainly be produced large effect.

Based on the above-mentioned problems in the prior art, in the preferred embodiment of the present invention, it is provided that a kind of services set scan control method that intersects.This scan control method is applied under dual network pattern the mobile terminal coexisted.Coexist under so-called dual network pattern, refer to that mobile terminal can simultaneously work under two different network schemers, and connect corresponding opposite equip. respectively, and share a set of transceiver (RF+PHY).Such as, mobile terminal simultaneously works under STA mode and P2P pattern, the AP equipment of peer end of the connection when working under STA mode, and when P2P MODE of operation: 1) if working with P2P_GO pattern, namely as GO equipment (GroupOwner under P2P pattern, group has end) time, the GC equipment (GroupClient organizes client) of peer end of the connection；2) if with P2P_GC pattern work, namely under P2P pattern as GC equipment time, the GO equipment of peer end of the connection.

In the preferred embodiment of the present invention, first trigger to set up processing the period accordingly according to scanning process.So-called scanning process triggers, it is possible to for the upper layer device (not shown) corresponding scan instruction of transmission to infrastructure devices, for instance the top level control central apparatus of mobile terminal sends scan command etc. to mobile terminal.

In the present invention, no longer upper layer device described below is explained in detail.

In the preferred embodiment of the present invention, setting up and process the period accordingly, the total operating time carrying out OBSS scanning by mobile terminal is divided into corresponding multiple process period.

In the preferred embodiment of the present invention, after setting up the corresponding process period, mobile terminal can carry out OBSS scanning within each process period under one of them network schemer.Such as: for STA+P2P is double mode coexist for, within a predetermined process period, under STA mode, carry out OBSS scanning, and after STA has scanned, within the process period that another is predetermined, under P2P pattern, carry out OBSS scanning.Said process can move in circles execution, then constitute time division multiplex transceiver (RF+PHY) and carry out the process of OBSS scanning.

In the preferred embodiment of the present invention, after setting up the corresponding process period, the scanning channel being not yet scanned through being applied in the multiple scanning channels under one of them network schemer can be carried out OBSS scanning by mobile terminal within each process period.So-called scanning channel, for working channel.Scanning channel is the channel that mobile terminal carries out being stationed when OBSS scans, and working channel refers to the channel that mobile terminal is stationed during normal operation under corresponding network schemer.In other words, mobile terminal, when carrying out OBSS scanning, switches to from original working channel and scans channel accordingly, and after completing OBSS scanning, switches back into original working channel from scanning channel.

In sum, in the preferred embodiment of the present invention, after dividing the corresponding process period, within each process period, mobile terminal scans channel to one under one of them network schemer and carries out OBSS scanning.Such as: under STA+P2P pattern, mobile terminal processes in the period at first and under STA mode, a scanning channel is scanned；Process in the period at second and under P2P pattern, a scanning channel is scanned；Process to return in the period at the 3rd and under STA mode, another scanning channel being not yet scanned through is scanned；Process to return in the period at the 4th and under P2P pattern, another scanning channel being not yet scanned through is scanned.Above-mentioned scanning process moves in circles such that it is able to complete the OBSS scanning of all scanning channels under STA mode and P2P pattern.Therefore, said process can realize the OBSS scan method of mobile terminal time sharing segment under dual network pattern coexists.

In the preferred embodiment of the present invention, the OBSS scanning process that above-mentioned concrete example illustrates only skilled artisan understands that technical solution of the present invention for convenience, not thereby limits protection scope of the present invention.Heretofore described OBSS scan mode still can adopt additive method to realize under the major premise of time sharing segment.

Specifically, in the preferred embodiment of the present invention, as in figure 2 it is shown, above-mentioned OBSS scan control method specifically includes:

Step S1, is ready under one of them network schemer and carries out intersection services set scanning accordingly, and total working duration is divided into corresponding multiple process period；

In the preferred embodiment of the present invention, as described above, the scan instruction generally issued by upper layer device triggers OBSS scanning.Therefore, in above-mentioned steps S1, process the period accordingly according to the scan instruction division that corresponding upper layer device issues, to be ready for this OBSS scanning.

In the preferred embodiment of the present invention, in above-mentioned steps S1, divide and process the period accordingly, and unlatching scans intervalometer accordingly, to judge to process whether the period starts accordingly；

Step S2, when the corresponding process period starts, starts the one scan channel being not yet scanned through under one of them network schemer carries out intersection services set scanning；

In the preferred embodiment of the present invention, when the corresponding process period starts, namely in scanning intervalometer, corresponding timeslice then, then scans channel to corresponding one and carries out OBSS scanning.

In the preferred embodiment of the present invention, before the scanning channel that certain is predetermined carries out OBSS scanning, first mobile terminal switches to this scanning channel that will be scanned under one of them network schemer.

Step S3, judge whether the corresponding scanning channel under two network schemers exists the application that network delay or network jitter is sensitive, and on scanning channel, when existing the application that network delay or network jitter are sensitive under a network schemer, carry out intersection services set scanning actively, to obtain corresponding scanning information.

In the preferred embodiment of the present invention, so-called network delay, refer to that data are transmitted the time used in Network Transfer Media, namely initially enter, from data message, the time that network initially moves off network to data message.So-called network jitter, refers to the intensity of variation of packetization delay in network.Above-mentioned two data are generally used for the service quality (QualityofService, QoS) judging in network.Therefore, if there being application (or being called Network) that network delay or network jitter is more sensitive, namely refer to that this application is higher for the requirement of network service quality, for instance real time phone call business etc..Therefore, scan if carried out OBSS, it is possible to influence whether this working condition than more sensitive application.

Then in the preferred embodiment of the present invention, namely the purpose of above-mentioned steps S2 is in that by judging under two network schemers, whether respective scanned channel exists to network delay or network jitter than more sensitive application, thus selecting different scanning strategys to perform OBSS scanning according to judged result.Specifically, in the preferred embodiment of the present invention, if being currently needed for when the scanning the application existed in channel network delay or network jitter sensitivity of two network schemers of scanning, then adopt more careful scanning strategy, to avoid OBSS scanning that this application is produced impact.

In the preferred embodiment of the present invention, above-mentioned OBSS scanning is divided into two kinds of scan modes according to the difference of judged result:

The first scan mode is the active scan of OBSS.So-called active scan, refers to that opposite equip. is actively carried out OBSS scanning by mobile terminal under corresponding current network pattern on corresponding scanning channel, namely actively sends scan request frame to opposite equip..Such as, for the active scan carrying out OBSS under STA mode, STA equipment actively sends scan request frame to AP equipment, such as ProbeRequest, wherein can carry corresponding service set (ServiceSetIdentifier, SSID) or use empty service set (NullSSID).

The second scan mode is the drive sweep of OBSS.So-called drive sweep, refers to that mobile terminal does not carry out active scan under corresponding current network pattern, and waits that opposite equip. sends corresponding scanning frame and is just scanned.Such as, for the drive sweep carrying out OBSS under STA mode, STA equipment waits that AP equipment sends corresponding scanning frame, for instance waits that AP equipment sends beacon frame, and obtains corresponding scanning information according to beacon frame.

Then in the preferred embodiment of the present invention, as noted before, if judging to exist on current scanning channel the application that network delay or network jitter is sensitive, then it represents that Current Scan channel exists and compares the application relying on network QoS, for instance real time phone call business.Then now mobile terminal adopts OBSS scanning actively, OBSS is searched on this scanning channel, and in scanning process, consider the existence of sensitive traffic, carry out channel-monitoring in short-term, namely the short time monitors scanning channel to receive corresponding scanning information, the impact of sensitive traffic is preferably minimized OBSS scanning.

In the preferred embodiment of the present invention, in above-mentioned steps S3, if judging that scanning channel exists sensitive application, then as it is shown on figure 3, specifically perform following step:

Step S31A, it is judged that whether there is the application that network delay or network jitter is sensitive in the scanning channel will being scanned under one of them network schemer:

If being absent from the application that network delay or network jitter is sensitive, then go to step S33A；

Step S32A, it is judged that except whether there is the application that network delay or network jitter is sensitive in the scanning channel under another network schemer of current network pattern:

In the preferred embodiment of the present invention, if being absent from the application that network delay or network jitter is sensitive, then it is made directly next step.

Step S33A, carries out active scan to the intersection services set of scanning channel, to obtain corresponding scanning information.

In the preferred embodiment of the present invention, in active scan, as mentioned above it is possible, mobile terminal monitoring and controlling channels in short-term, to obtain corresponding scanning information.

In the preferred embodiment of the present invention, correspondingly, as shown in Figure 4, above-mentioned steps S3 can also include:

Step S31B, it is judged that whether there is the application that network delay or network jitter is sensitive in the scanning channel will being scanned under one of them network schemer:

Step S32B, it is judged that whether there is the application that network delay or network jitter is sensitive in the scanning channel under another network schemer except one of them network schemer:

Step S33B, carries out intersection services set scanning actively or passively, to obtain corresponding scanning information on scanning channel.

Correspondingly, in the preferred embodiment of the present invention, if judging to be absent from current scanning channel the application that network delay or network jitter is sensitive, then can carry out active or passive OBSS scanning, and relatively go up a kind of scan method, long period monitors scanning channel, to receive corresponding scanning information.

In sum, in the preferred embodiment of the present invention, before performing intersection services set scanning, first determine whether whether the scanning channel under two network schemers exists sensitive application:

If the scanning channel under two network schemers is all absent from the application that network delay or network jitter is sensitive, then scan mode actively or passively is adopted to carry out intersection services set scanning；

If the scanning channel under two network schemers has the application that network delay or network jitter is sensitive, then scan mode actively is adopted to carry out intersection services set scanning.In the preferred embodiment of the present invention, after having performed above-mentioned steps S3, as it is shown in figure 5, perform following step:

Step S4, it is judged that whether this intersection services set scanning terminates:

Step S5, updates the scanning channel that scanning next time is corresponding, and returns step S2.

In the preferred embodiment of the present invention, judge that this intersects services set and scans still unclosed reason and be likely to have multiple, such as this intersection services set scanning not yet covers all scanning channels, or this intersection services set scanning result is made mistakes, or occurs abnormal conditions process etc. in scanning process.Technical solution of the present invention repeats no more for the still unclosed judgement of scanning.

In the preferred embodiment of the present invention, if judging, this OBSS scanning not yet terminates, then update the next one and will carry out the channel of OBSS scanning, and open the scanning intervalometer of correspondence, it is then returned to above-mentioned steps S2, waiting timer timeslice arrives, and when namely the process period starts accordingly, carries out the scanning of next scanning channel.

In the preferred embodiment of the present invention, if judging this OBSS end of scan, then directly return step S1, wait that upper layer device sends scan command next time, to start OBSS scanning next time.

In the preferred embodiment of the present invention, support that STA+P2P is double mode for mobile terminal and coexist, above-mentioned whole OBSS scanning process is described.

In one preferred embodiment of the present invention, mobile terminal is normality work under STA mode, and carries out OBSS scanning under STA mode.Now mobile terminal works as GO equipment under P2P pattern, connects corresponding GC equipment.

The OBSS scanning process then under STA mode, corresponding scanning channel carried out as shown in Figure 6, specifically includes:

In the preferred embodiment of the present invention, the corresponding opposite equip. that mobile terminal connects under STA mode is AP equipment, and mobile terminal receives the scan instruction that the top level control equipment of mobile terminal sends under STA mode, and division processes the period accordingly.

Step S2a, when the corresponding process period starts, mobile terminal starts to scan channel to corresponding one under terminal pattern and is scanned, it is judged that whether there is the application that network delay or network jitter is sensitive in the scanning channel under terminal pattern:

Step S3a, it is judged that whether there is the application that network delay or network jitter is sensitive in the scanning channel under ad hoc mode:

Step S4a, it is judged that whether there is the application that network delay or network jitter is sensitive in the opposite equip. that mobile terminal connects under ad hoc mode:

In the preferred embodiment of the present invention, in above-mentioned steps S3a and step S4a, in P2P pattern, mobile terminal judges whether self (namely as GO equipment) and GC equipment associated there exist the application (all on corresponding scanning channel) that network delay or network jitter is sensitive, for instance real time phone call business etc.；And when being all absent from sensitive application in above-mentioned two equipment, just carry out the OBSS such as step S5a and scan, as long as and above-mentioned two equipment has one there is sensitive application on corresponding scanning channel, namely carry out the OBSS scanning as described in step S6a.

Step S5a, carries out intersection services set scanning actively or passively on scanning channel, to obtain corresponding scanning information, then switches into step S7a；

Step S6a, carries out intersection services set scanning actively, to obtain corresponding scanning information on scanning channel；

Step S7a, mobile terminal switches back on the working channel of original work under terminal pattern, and judges whether this intersection services set scanning terminates；

If this intersects the services set end of scan, then directly return step S1a；

Step S8a, updates the scanning channel that scanning next time is corresponding, and returns step S2a.

In one preferred embodiment of the present invention, mobile terminal is normality work under STA mode, and carries out OBSS scanning under P2P pattern.Now mobile terminal works as GO equipment under P2P pattern, connects corresponding GC equipment.
