Fig. 8 shows the instantiation schematic diagram according to the method for the dispatch terminal of the embodiment of the present invention, as shown in Figure 8, can, with reference to wireless access network shown in Fig. 2, this embodiment be described, and specifically comprises the following steps:

Step S802, one group of candidate band is determined for multiband scheduling in frequency spectrum corporate management unit 208, specifically implements by following three steps.

The first step, one group of potential frequency band is determined for terminal in frequency spectrum corporate management unit 208.

Particularly, M the frequency band that frequency spectrum corporate management unit 208 has from ownership radio-frequency channel place radio node and the relevant radio node thereof of terminal, choosing can be by the frequency band of N available free time slot of terminal-receiving passage or transmission channel covering as channel measurement frequency band, wherein, above-mentioned relevant radio node can be one of following radio node: the radio node of the community adjacent with community, terminal place, or, under layered network architecture, cover the radio node of other one deck of community, terminal place; Further, in order to reduce the surveying work amount of terminal, in multiple frequency bands of a shared same antenna, only choose one of them and carry out channel measurement.

Second step, carries out channel measurement in the mode of specifying on the potential frequency band that terminal is specified in frequency spectrum corporate management unit 208, below the specific implementation process of this step is described in detail.

First, the ownership passage of frequency spectrum corporate management unit 208 by terminal sends potential frequency band carried out to the instruction of channel measurement to terminal on the ownership frequency band of terminal, and this channel measurement instruction comprises: the numbering of frequency band to be measured, use place, the radio-frequency channel radio node of frequency band to be measured or the numbering of antenna used, terminal on potential frequency band, to carry out the mode of channel measurement; Then frequency band and metering system that, terminal is specified according to network are measured and calculating path loss parameter potential frequency band.

Wherein, the mode that terminal is carried out channel measurement on potential frequency band has following two kinds:

(1) terminal sends predetermined channel detection signal to network on frequency band to be measured, one or more radio node of network side receive channel detectable signal calculate the path loss between terminal and radio node on this frequency band on corresponding frequency band.

(2) terminal receives from the known measuring-signal of the form of one or more radio node on frequency band to be measured, and calculates the path loss between terminal and radio node on this frequency band, and measurement result is reported to frequency spectrum corporate management unit 208.

The method of above-mentioned terminal transmitting channel detectable signal on potential frequency band is: a transmission channel of terminal uses on the frequency band that two antennas of terminal are identical to network transmitting channel detectable signal in the mode of time-division, and one or more radio node of network side channel detection signal that synchronously receiving terminal sends computing terminal are to channel impulse response data and the path loss of above-mentioned radio node; In the time that radio node comprises multiple reception antenna, path loss is that each transmitting antenna of terminal is to the mean value of one group of path loss of one group of reception antenna.

The method of above-mentioned terminal receive channel detectable signal on potential frequency band is: two transmission channels of terminal receive the known measuring-signal of form that radio node sends the channel impulse response that calculates every group of dual-mode antenna simultaneously; In the time that radio node comprises multiple transmitting antenna, path loss is the mean value of the path loss between the transmitting antenna on each reception antenna and one group of radio node of terminal, and terminal reports network by its ownership frequency band by the measured value of path loss.

The 3rd step, the candidate band of one group of multiband scheduling is determined in frequency spectrum corporate management unit 208 to the measurement result of potential frequency band according to terminal.

Particularly, frequency spectrum corporate management unit 208 compares terminal on potential frequency band with the path loss of different radio node and the thresholding TH_los of reservation, and a surviving path loss is less than the potential frequency band on the radio node of subscribing thresholding TH_los; The potential frequency band that frequency spectrum corporate management unit 208 is less than the path loss remaining on the radio node of subscribing thresholding TH_los sorts according to the size of its path loss, when two or more candidate band are while belonging to the same frequency band of different radio node, only retain corresponding that candidate band of radio node of a path loss minimum, consequently, in the candidate band of selecting, there is not the frequency band repeating.

Step S804, target band and mode of operation thereof are determined in frequency spectrum corporate management unit 208 from candidate band, particularly, can implement by following three steps.

The first step, frequency spectrum corporate management unit 208 takies logging modle and obtains the idle frequency spectrum resource data of each candidate band from frequency spectrum, and make the following judgment: judge whether the needed frequency spectrum resource of business that exists its idle frequency spectrum resource of a frequency band can meet terminal request, for be in the situation that, proceed to second step in judged result; In judged result be no in the situation that, further judge whether to exist two or more its free timeslots to have in time staggered frequency band, and be there is to the needed frequency spectrum resource of business that can meet terminal request after being connected in series successively use with the frequency spectrum resource on the staggered free timeslot in time of different frequency bands in these, in the case of the judged result further judging be, proceed to the 3rd step, in the case of the judged result further judge be no, stop the credit rating of the business of multiband scheduling to terminal or reduction terminal request.

Second step, the target band that frequency spectrum corporate management unit 208 is dispatched an above-mentioned single frequency band as multiband.

The 3rd step, the target band of frequency spectrum corporate management unit 208 scheduling using two or frequency band as multiband, and determine an order that uses successively the free timeslot in these target band for terminal.

Step S806, frequency spectrum corporate management unit 208 sends multiband dispatch command by ownership frequency band to terminal.

Wherein, the multiband dispatch command sending comprises following content: the numbering of the numbering of definite target band, target band place WAP (wireless access point) and the occupation mode of terminal to target band in step S804, and terminal comprises one of following mode to the occupation mode of target band: terminal is used a target band to transmit data, terminal is used successively two or more target band to transmit serially data in a radio frames.

Further, dispatch command is the position of terminal assignments running time-frequency resource of transmitting channel detectable signal in target band; Network, according to the result of channel detection, transmits the wireless link form of data between the terminal of working in target band for terminal assignments further and network, above-mentioned wireless link form is one of following: space diversity, spatial reuse.

After terminal is received above-mentioned dispatch command, the mode indicating according to dispatching command, terminal communicates with network in target band, or terminal communicates with another one terminal in target band.

Below in conjunction with the method shown in Fig. 8, be elaborated to terminal being carried out to multiband scheduling in downlink transfer, and with reference to Fig. 2, Fig. 5 and Fig. 6, this example is described, wherein, can form an isomery multiband distributed communication system according to the multichannel terminal shown in the heterogeneous radio access networks shown in Fig. 2, Fig. 6 and the networking mode shown in Fig. 5.

Below with reference to the networking mode shown in Fig. 5, be given in the specific implementation method of dispatch terminal 503a between different frequency bands.Before multiband scheduler module in the joint spectrum administrative unit of network side is carried out multiband scheduling to terminal 503a, the frequency band 302 of terminal 503a on radio node 501 be last has completed Cell searching and synchronous, and access control module in frequency spectrum corporate management unit 208 is by the 302 ownership frequency bands of being appointed as this terminal.The radio-frequency channel reporting parameters module 608 of terminal 503a reports its radio-frequency channel parameter to network side respectively, this radio-frequency channel parameter specifically comprises: the transmission channel 606 of terminal has the ability that covers frequency band 301,304, and two receive path 602,604 has the ability that covers frequency band 301, frequency band 302, frequency band 303.

First, one group of candidate band is determined for multiband scheduling in frequency spectrum corporate management unit 208, is divided into three steps below and carries out this process to be described in detail.

The first step, 3 of having from place, the ownership radio-frequency channel radio node 502b of terminal 503a and relevant radio node 502a, radio node 502c and radio node 501 in frequency spectrum corporate management unit 208 can be used for the frequency band 301,302,303 of downlink transfer, choose the frequency band 301,302,303 of 3 available free time slots that can be covered by terminal-receiving passage or transmission channel as channel measurement frequency band.

Second step, carries out channel measurement in the mode of specifying on the potential frequency band 301,302,303 that terminal is specified in frequency spectrum corporate management unit 208.

Particularly, frequency spectrum corporate management unit 208 is sent potential frequency band is carried out to the instruction of channel measurement to terminal on the ownership frequency band of terminal by the ownership passage of terminal, channel measurement instruction comprises: frequency band 301 to be measured, 302, 303 numbering, use place, the radio-frequency channel radio node 501a of frequency band to be measured, 502b, 502c and 501 numbering, and designated terminal is at frequency band 301 to be measured, 302, on 303, receive from

radio node

501a, 502b, 502c and 501 measuring-signal, and calculate on this frequency band channel impulse response and the path loss between every pair of dual-mode antenna between terminal and radio node, and measurement result is reported to frequency spectrum corporate management unit 208, particularly, terminal is to from radio node 501a, 502b, the measuring-signal of 502c and 501 FDD down going channel is reference signal (the Reference Signal Received Power switching for community, referred to as RSRP), terminal is reference signal or the antenna identification signal of the transmitting of MBMS system to the measuring-signal of the frequency band 303 on 501.

Particularly, frequency spectrum corporate management unit 208 compares terminal on potential frequency band 301,302,303 with the path loss of different radio node and the thresholding TH_los of reservation, surviving path loss is less than the potential frequency band on the radio node of subscribing thresholding TH_los, and the result obtaining is: only have the frequency band on radio node 502b and radio node 501 to be retained, after this, the potential frequency band that frequency spectrum corporate management unit 208 is less than the path loss remaining on the radio node of subscribing thresholding TH_los sorts according to the size of its path loss, see Fig. 8 according to terminal to the ranking results of the path loss of radio node, increase successively from first its path loss of frequency band to the three frequency bands, the reason that causes path loss between radio node 501 and terminal to be less than radio node 502b is that the decorating position that radio node 501 is high makes the propagation path having had between radio node 501 and terminal, so 301, 302, 303 as candidate band.

Secondly, target band and mode of operation thereof are determined in frequency spectrum corporate management unit 208 from candidate band, be divided into two steps below this process is described in detail.

The first step, frequency spectrum corporate management unit 208 takies the idle record of logging modle to the different frequency bands on each radio node according to frequency spectrum, obtains the current idle data of frequency band 301,302,303, sees Fig. 9 (a).Then, judge the spectrum requirement that whether has a frequency spectrum resource on its free timeslot of frequency band can meet the business that terminal asks in frequency band 301,302,303, can meet the demands if judged result is the frequency spectrum resource on the free timeslot on frequency band 301, proceed to second step.

In above-mentioned scheduling process, if to whether exist its idle frequency spectrum resource of a frequency band can meet terminal request the needed frequency spectrum resource of business judged result whether, frequency spectrum corporate management unit 208 further does as judged: in

candidate band

301, 302, in 303, whether exist two its free timeslots to have in time staggered frequency band, and be there is to the needed frequency spectrum resource of business that can meet terminal request after being connected in series successively use with the frequency spectrum resource on the staggered free timeslot in time of different frequency bands in these, judged result is, see Fig. 9 (b): by the idle frequency band in frequency band 301 descending time slots 1., 2. free timeslot in frequency band 302 passes the needed frequency spectrum resource of business that connects use and can meet terminal request.

Second step, the target band that frequency spectrum corporate management unit 208 is dispatched above-mentioned frequency band 301 as multiband, and by the frequency spectrum resource on frequency band 301 free timeslots 1. assignment use to terminal.

Finally, frequency spectrum corporate management unit 208 sends multiband dispatch command by ownership frequency band to terminal; Wherein, the multiband dispatch command of transmission comprises one of at least following content: position indication 1. of the frequency spectrum resource on the numbering of the determined target band 301 of step S804, numbering, frequency band 301 free timeslots of target band 301 place WAP (wireless access point) 502b and the running time-frequency resource position of terminal 503a transmitting channel detectable signal in target band 301.
