Embodiment 2

According to an embodiment of the invention, a kind of frequency-selecting method of access device is provided, the frequency-selecting method of the access device For being quickly that access device selects suitable working band.

Fig. 3 is the flow chart of the frequency-selecting method of access device according to an embodiment of the present invention.As shown in figure 3, this method packet Include following step S302 to step S308:

Step S302 obtains the configuration information of access device;

Step S304 determines the frequency band detection ordering of access device according to configuration information, and frequency band detection ordering is for detecting Whether the signal strength on alternative band exceeds predetermined threshold value, and alternative band includes target band;

Step S306 detects whether the signal strength in target band exceeds predetermined threshold value according to frequency band detection ordering; And

Step S308, if detecting the signal strength in target band without departing from pre-determined threshold according to frequency band detection ordering Value, then using target band as the working band of access device.

Access device and its with the connection relationships of other network equipments with embodiment 1, details are not described herein.

When implementing, access device can obtain the configuration information of itself from other network equipments, for example, it can be from The configuration information of itself is obtained at access control equipment.Access device is determining the frequency band detection ordering of itself according to configuration information When, the frequency band occupied by other neighboring access equipment can be rejected automatically, prevent from excessively repeating to detect this by it Frequency band that his neighboring access equipment occupies and cause delay longer.

For example, access device obtains configuration information from the access control equipment being connected with itself, and according to acquisition Configuration information determines frequency band detection ordering, and then strong according to the signal that the frequency band detection ordering detects at least two alternative bands Degree.It is if detecting that the signal strength of wherein some alternative band (that is, target band) is lower than predetermined threshold value, this is alternative Frequency band (that is, target band) is chosen to be the working band of access device;If detecting the signal on wherein some alternative band Intensity is higher than the predetermined threshold value, then detects next alternative band again (that is, target frequency according to frequency band detection ordering above-mentioned Band), until the working band for determining access device.

Since access device detects the sequence of the available band in all alternative bands by coupled another equipment It configures, therefore it is more and access is caused to be delayed longer problem to can be avoided access device in the same area.For example, it is assumed that same 4 access devices, respectively access device 2041 to access device 2044 are provided in one region altogether, if these access devices Successively transmit wireless signal according to the size order of device coding, then before above-mentioned access device transmits wireless signal, access Equipment 2041 can begin trying to access from frequency band 1, access device 2042 can begin trying to access from frequency band 2 ... ... in this way, All access devices can be made, which only to pass through one-time detection just, can determine that the working frequency range of itself, as shown in figure 4, due to all accesses Equipment is all connected to same access control equipment 202, therefore can effectively reduce these multiple access devices and attempt detection difference The number of the signal strength of frequency band.

It should be noted that in embodiments of the present invention, access device can connect to terminal, which can be by connecing Enter equipment and obtains corresponding communication service from wireless access network.In embodiments of the present invention, the concrete form of terminal is not limited It is fixed, for example, it can be mobile phone, mobile phone and other electronic equipments that can send or receive wireless signal, including Personal digital assistant (PDA), wireless modem, wireless communication device, hand-held device, laptop computer, wireless phone, Wireless local loop station (WLL), intelligent appliance, other is not required to CPE or Mifi that movable signal can be converted to wifi signal Want user's operation can the spontaneous equipment etc. with the communication equipment progress information exchange in mobile communications network.

Above-mentioned alternative band includes one or more.When it only includes one, the alternative band is i.e. chosen For the working band of access device;When it includes multiple, multiple alternative band can all be licensed frequency band, Huo Zheqi It can all be Unlicensed frequency band.Preferably, these alternative bands can all be the latter, and the present invention is more particularly to avoiding The problem of frequency band collision that may occur when transmitting wireless signal on Unlicensed frequency band.

Through the embodiment of the present invention, the letter of detection different frequency bands is attempted since these multiple access devices can be effectively reduced The number of number intensity, therefore achieved the effect that reduce delay of the access device when selecting working band.

Preferably, in embodiments of the present invention, step S304 determines that the frequency band detection of access device is suitable according to configuration information Sequence may include various ways.Such as:

Mode 1:S2 determines target random sequence or first object random number according to configuration information;S4, according to confidence When breath determines target random sequence, the frequency band detection ordering of access device is determined according to target random sequence;And S6, in root When determining first object random number according to configuration information, detection of the access device to target band is determined according to first object random number Order.

In when implementing, since access control equipment can not accurately obtain the geographical location of all access devices, in addition, by State in the channel of each access device unlatching/closing transmission wireless signal be dynamic change (for example, for wifi, Access device can just open the channel of transmission wireless signal before having service signal to need to send, convenient for reducing power consumption, and business The randomness that the randomness of signal necessarily causes access device to be opened), and the channel for transmitting wireless signal is also dynamic change, Therefore, access control equipment can not be obtained accurately whether there is between the current state and different access device of access device Interference etc., therefore, each access device can not determine optimal frequency band detection ordering accurately to further decrease itself to alternative The detection number of frequency band.

In order to overcome the above problem, in embodiments of the present invention, access device pass-through mode 1 is further creatively proposed Determine frequency band detection ordering.For through a target random sequence, which is access device according to itself Configuration information determine.For example, access device 1, access device 2 of the access control equipment into the same area send them respectively From different configuration informations, the two access devices can determine therefrom that respectively different random sequences, and according to respective difference Random sequence determine respectively different frequency band detection ordering.For example, access device 1 according to the configuration information of itself determine with Machine sequence is 1,5,7,22,13 ..., corresponding frequency band detection ordering be Band1, Band5, Band7, Band22, Band13……;Access device 2 is 2,11,8,10,3 ... according to the random sequence that the configuration information of itself determines, corresponding Frequency band detection ordering is Band2, Band11, Band8, Band10, Band3 ...;In this way, access device 1 is first examined when opening Survey Band1 signal strength, if testing result shows that its signal strength is weaker, using the frequency band as itself work frequency Band;Access device 2 first detects the signal strength of Band2 when opening, if testing result shows that its signal strength is weaker, Using the frequency band as itself working band, the two access devices can determine its respective working band quickly as a result,.In This, does not limit access device and has to first generate entire random sequence (that is, target random sequence), detects random sequence one by one again The signal strength of corresponding each alternative band, for example, access device can be in the signal strength for detecting each alternative band Before, random number corresponding to the alternative band (that is, first object random number) is calculated.It should be noted that either target Random sequence or target random number, numerical value in random sequence corresponding to the alternative band that access device detects every time or The random number directly calculated can be determined by same algorithm or same formula.

In embodiments of the present invention, the number of target random sequence not necessarily corresponds to identical, example with the number of alternative band Such as, random sequence f (i) is 1,5,7,22,13 ..., and the number for the alternative band that sequence determines accordingly can be f (i) mod10, That is, f (i) mod10 is 1,5,7,2,3 ..., wherein mod indicates modulo operation.

Mode 2:S8 determines the second target random number and hash function according to configuration information;And S10, according to the second mesh Mark random number and hash function determine the frequency band detection ordering of access device.

It should be noted that first object random number is different from the second target random number.First object random number can be straight Connect the detection number for determining each alternative band;And the second target random number is in the detection number of determining each alternative band Variable calculates corresponding cryptographic Hash, then phase calculated that is, needing first to bring the second target random number into hash function The cryptographic Hash answered determine indirectly each alternative band detection number.

When implementing, it is assumed that include multiple access devices in the same region, and they open transmission wireless signal Channel sequencing be it is random, in order to shorten the time that each access device determines the working band of itself as far as possible, then Need to reduce the number of access device detection alternative band, it is therefore desirable to reduce any one access device alternative frequency detected Band probability identical with the working band that other access devices have occupied (that is, probability of frequency band collision) is to realize above-mentioned mesh 's.

Since in mathematical region, hash function can reduce the probability of random collision as far as possible, therefore, touched to reduce frequency band The probability hit creatively proposes the frequency band that access device is determined using hash function (HASH) in embodiments of the present invention Detection ordering.

For example, it is assumed that hash function is (Y+m) mod N, wherein N indicates the number of alternative band, and m indicates frequency band detection The number of each alternative band corresponding to sequence, Y indicate random number;If N=8, and the corresponding Y=3 of an access device, Then frequency band detection ordering is (3+m) mod 8, that is, frequency band detection ordering is 4,5,6,7,0,1,2 ..., wherein corresponding m= 1,2,3…….In this way, if in the configuration information that access control equipment is sent to different access devices including different be used for Determine the information of the numerical value of random number Y, then the frequency band detection ordering of these different access devices is also just different, so as to drop The probability of low-frequency band collision.For example, the corresponding Y=5 of another access device, then frequency band detection ordering be just 6,7,0,1, 2 ..., different from the frequency band detection ordering 4,5,6,7,0,1,2 ... of aforementioned access device.

It should be noted that in the present invention is implemented, not made according to determination method of the configuration information to the numerical value of random number Y It limits.For example, can directly include the numerical value of random number Y in configuration information;Alternatively, can only include random in configuration information The numerical value of each Y is calculated according to the initialization value of random number Y for an initialization value of number Y, access device.For example, can To calculate the numerical value of random number Y by formula Y (t)=[A × Y (t-1)] mod D, wherein A and D is fixed value, for example, A= 39827, D=65537, Y (- 1) are the initialization value for the random number for including in configuration information;T indicates the t times unlatching wireless transmission The number t of channel.

Preferably, in embodiments of the present invention, before the configuration information that step S302 obtains access device, the frequency-selecting side Method can also include:

The available machine time of the location information of access device and/or access device is sent to access control equipment by S12, In, access control equipment is used in the location information for receiving access device, generates the first configuration information according to location information; Alternatively, generating the second configuration information according to the available machine time in the available machine time for receiving access device;Alternatively, receiving When the available machine time of the location information of access device and access device, third is generated according to location information and available machine time and matches confidence Breath.

For example, access device first sends geographical location information to access control equipment, access control equipment is according to the geography Location information determines configuration information, which is used for so that the closer different access devices in geographical location use different frequencies The available band in alternative band is detected with detection ordering;Alternatively, access control equipment is opened according to access device The sequencing for transmitting the channel of wireless signal determines configuration information, which is used to guarantee to connect what different time was opened Enter equipment using different frequency band detection orderings to detect to the available band in alternative band;Alternatively, access control is set The sequencing and geographical location information of the standby channel that transmission wireless signal is opened according to access device determine configuration information, this is matched Confidence breath is for guaranteeing that access devices in different time unlatching and that geographical location is different use different frequency band detection orderings To be detected to the available band in alternative band.Above-mentioned 3 kinds of modes can achieve identical effect.

Preferably, in embodiments of the present invention, alternative band may include multiple, and multiple alternative bands are same band It frequency band and is not overlapped on frequency domain, convenient for reducing the number of alternative band.Unlicensed frequency band is limited, and different connects The corresponding bandwidth of working band for entering equipment is different, different (e.g., the voice communications of band bandwidth needed due to different communication business The transmission rate needed is low, and corresponding band bandwidth is with regard to small;The transmission rate that video traffic needs is high, and corresponding band bandwidth is just Greatly), it is therefore desirable to the alternative band of access device detection different bandwidth.For example, the 5150- for being 200MHz for bandwidth For this frequency band of 5350MHz, it can be divided into the frequency band that 10 bandwidth are 20MHz, 20 can also be divided into Bandwidth is the frequency band of 10MHz.

Preferably, in embodiments of the present invention, multiple alternative bands may be the frequency band of different bandwidth and on frequency domain It is overlapped.For example, access device can first detect the alternative band that 10 bandwidth are 20MHz, then to 20 bandwidth It is detected for the alternative band of 10MHz, and alternative band and 20 bandwidth that 10 bandwidth are 20MHz are the alternative of 10MHz All corresponding this big frequency band of such as 5150-5350MHz of frequency band, the i.e. corresponding frequency band of both schemes are completely overlapped.

Preferably, in embodiments of the present invention, alternative band may include first kind alternative band and the alternative frequency of the second class Band, wherein alternative band can be classified based on amount of bandwidth or frequency height.

For example, when the corresponding band of first kind alternative band is wider than the corresponding bandwidth of the second class alternative band, step S304 determines that the frequency band detection ordering of access device may include: to determine that the first kind is alternative according to configuration information according to configuration information The first band detection ordering of frequency band, using first band detection ordering as the frequency band detection ordering of access device;Alternatively, according to Configuration information determines the first band detection ordering of first kind alternative band, and determines the second band inspection of the second class alternative band Survey sequence, first using first band detection ordering as the frequency band detection ordering of access device, then second band detection ordering is made For the frequency band detection ordering of access device,

Since big bandwidth can bring better transmission rate and better communication service, it is therefore preferred that access device can With the first alternative band to big bandwidth with the application of the invention, again to the alternative band application present invention of small bandwidth.For example, access device The first corresponding alternative band of detection 20MHz, then detect the corresponding alternative band of 10MHz.

For another example first kind alternative band frequency be lower than the second class alternative band frequency when, step S304 according to Configuration information determines that the frequency band detection ordering of access device may include: to determine the of first kind alternative band according to configuration information Three frequency band detection orderings, using third frequency band detection ordering as the frequency band detection ordering of access device;Alternatively, according to configuration information It determines the third frequency band detection ordering of first kind alternative band, and determines the 4th frequency band detection ordering of the second class alternative band, First using third frequency band detection ordering as the frequency band detection ordering of access device, then using the 4th frequency band detection ordering as access set Standby frequency band detection ordering.

Since the wireless signal area coverage of low-frequency band is wider, transmission quality is more preferable, in the embodiment of the present invention In, access device can first detect the alternative band in low-frequency range, then detect the alternative band on high band.For example, alternative frequency The alternative band and the total 80MHz on 2400MHz~2480MHz that band includes the total 200MHz on 5150MHz~5350MHz Alternative band, access device can first the alternative band to the total 80MHz on 2400MHz~2480MHz with the application of the invention, again Alternative band to the total 200MHz on 5150MHz~5350MHz with the application of the invention, in such manner, it is possible to utilize low-frequency range as far as possible On alternative band provide more preferably communication service for user terminal.

Through the embodiment of the present invention, the side of the configuration information of access device is sent to access device using access control equipment Formula is that access device selects working band, and conveniently accessible equipment determines frequency band detection ordering, to reduce detection alternative band Number, and then achieve the effect that quickly to determine working band, improve user experience.
