Description
Technical field
The present invention relates to the access network technology of communication system, particularly a kind of method of transmitting between plate of realizing in the access network equipment.
Background technology
At present, along with the rapid expansion of communication requirement, the construction speed of access network equipment is accelerated greatly.Access network equipment generally includes: at least one master control veneer and the more than one veneer of being controlled by master control veneer.Wherein, the veneer of master control veneer control has two kinds: bandwidth requirement surpasses high speed veneer and the lower low speed veneer of bandwidth requirement of 1Mb/s.Directly be connected between master control veneer and the high speed veneer, then link to each other between low speed veneer and the master control veneer by interface single plate.A common interface single plate connects more than one low speed veneer by low speed bus, when low speed veneer quantity more for a long time, master control veneer also will connect a plurality of interface single plates, and each interface single plate connects the low speed veneer of some.Wherein, described access network equipment is at 2G network middle finger base station transceiver (BTS) and base station controller (BSC), and at 3G network middle finger base station node B and radio network controller (RNC).
When transmitting between plate, master control veneer will receive the data that mail to each veneer, then data is downloaded to each veneer.Because the low speed veneer will receive data from master control veneer by interface single plate, therefore, when data volume is big between the plate of low speed veneer transmission some problems will appear.Below in conjunction with Fig. 1 the problem that when transmission occurs between low speed veneer plate in the prior art is set forth.
Fig. 1 is the annexation schematic diagram between each veneer in the access network equipment.As shown in Figure 1, master control veneer connects three high speed veneers and two interface single plates.Wherein, interface single plate 1 connects four low speed veneers by low speed bus 1, comprising: category-A low speed veneer 11, category-B low speed veneer 11, category-B low speed veneer 12 and category-B low speed veneer 13; Interface single plate 2 connects four low speed veneers by low speed bus 2, comprising: category-A low speed veneer 21, category-A low speed veneer 22, category-B low speed veneer 21 and C class low speed veneer 21.
In the transmission method, master control veneer is followed successively by each low speed veneer data download by interface single plate between the plate that prior art provides.With Fig. 1 is example, is exactly specifically: master control veneer is followed successively by category-A low speed veneer 11, category-B low speed veneer 11, category-B low speed veneer 12, category-B low speed veneer 13 data download by interface single plate 1; Master control veneer is followed successively by category-A low speed veneer 21, category-A low speed veneer 22, category-B low speed veneer 21, C class low speed veneer 21 data download by interface single plate 2.Because it is just long that low speed bus limited bandwidth, monolithic veneer are finished the time that data download, so the total time of eight low speed veneer data download will be longer for master control veneer for this reason.If setting a low speed veneer data download required time is T, the data download required time of then finishing all low speed veneers is 8T.When the data volume of downloading is big, as upgrading base station etc., master control veneer is finished the time delay that all veneer data download will be quite long, thereby have a strong impact on base station performance.
Prior art also provides the method for transmitting between another kind of realization plate, and this method sends data to all low speed veneers that this interface single plate connects simultaneously by interface single plate.Because the low speed veneer is divided into polytype, the low speed veneer function of same type is identical, the desired data form is identical, inhomogeneous low speed veneer desired data difference, so each low speed veneer also will adopt strobe utility to select the data of self from the data that receive when receiving data.With Fig. 1 is example, be exactly specifically: master control veneer is with the data of category-A low speed veneer 11, category-B low speed veneer 11, category-B low speed veneer 12 and the category-B low speed veneer 13 of interface single plate 1 connection, be handed down to these low speed veneers simultaneously by interface single plate 1, category-A low speed veneer 11 filters the data that obtain category-A low speed veneer from the data that receive, category-B low speed veneer 11, category-B low speed veneer 12 and category-B low speed veneer 13 filter the data that obtain category-B low speed veneer from the data that receive.But this kind method will increase the load of master control veneer and interface single plate, and the processing of low speed veneer filtering data implements also more complicated.Because all data are transmitted simultaneously, and the bandwidth of low speed bus is less, so the resource contention fierceness on the bus, excessive resource contention will influence bandwidth availability ratio, thereby be difficult to guarantee desirable data speed of download.
Yet, in construction, maintenance and the dilation process of access network equipment, will inevitably will carry out transmitting between plate, and data volume be bigger usually.But, two kinds of methods that realize transmitting between plate that prior art proposes, realization effect more in veneer quantity, when data volume is big is unsatisfactory, availability is very poor.

Embodiment
The present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
The invention discloses a kind of method of transmitting between plate of realizing, be used to comprise the access network equipment of a master control veneer and an above veneer, its main design philosophy is: master control veneer is collected the type of each veneer in advance, and sets up the corresponding relation of each veneer and its type; When master control veneer carries out transmitting between plate, by collected board type, send data for successively all kinds of veneers, and at the only unified secondary data that sends of every class veneer.
Transmission comprises two kinds of situations between plate of the present invention: one, the transfer of data between master control veneer and the low speed veneer; Two, the transfer of data between master control veneer and the high speed veneer.Wherein, for each board type,, therefore can directly data be distributed to each high speed veneer of the type because the high speed veneer directly is connected with master control veneer; And the low speed veneer connects master control veneer by interface single plate, so master control veneer will at first determine to connect each interface single plate of each low speed veneer of the type, then data are distributed to this each interface single plate, send the data to each low speed veneer of the type again by each interface single plate.Below in conjunction with Fig. 2 the processing of the inventive method is elaborated.
Fig. 2 is the inventive method one preferred embodiment handling process schematic diagram.As shown in Figure 2, the concrete processing comprises:
Step 201: master control veneer is collected the type of current all veneers, and sets up the corresponding relation of each veneer and its type.
Here, described veneer can be low speed veneer or high speed veneer, in addition,, each veneer all has self unique sign usually, so the corresponding relation of each veneer of being set up and its type can be specially the corresponding relation of sign and its type of each veneer.The sign of described veneer can number be made up of cabinet number, frame number, groove.
Step 202: master control veneer is selected a board type from each collected board type.
Step 203: each veneer of each veneer that master control veneer is set up according to step 201 and corresponding relation determining step 202 selected types of its type, and send claim frame to each veneer of the type.
Step 204: when veneer successfully receives claim frame, return response and give master control veneer.Master control veneer receives the response from each veneer, and the veneer of determining to return response is current veneer to be downloaded.
In the present embodiment, master control veneer adopts the request transmission manner to come to send data to each veneer, that is to say: before real transmission data, at first send claim frame to each veneer, the veneer that successfully receives this claim frame will return response and indicate the preparation of self having carried out the reception data to master control veneer; Master control veneer as veneer to be downloaded, and sends data to these veneers to be downloaded with these veneers that return response, can avoid the transmission of some invalid datas like this.
Obviously, when veneer was the low speed veneer, master control veneer will at first be determined each interface single plate that each low speed veneer connects, and claim frame was sent to each low speed veneer of the type by each interface single plate; And when veneer was the high speed veneer, master control veneer can directly send to claim frame each high speed veneer of the type.
Step 205: each veneer to be downloaded that master control veneer is determined to step 204 sends the data of current selected board type correspondence.By background technology as can be known, the data format that each type veneer can receive is different, and therefore, the data that mail to certain class veneer should be the data format of such veneer correspondence.
Here, the transmission of data is unit with the frame, each corresponding one or more Frames of data possibility that send, in the Frame process of transmitting, also to consider processing details such as overtime re-transmission, data verification, because these handle details not within the discussion scope of this patent, so this paper no longer describes in detail.
Wherein, when veneer was the low speed veneer, master control veneer sent data by interface single plate to each low speed veneer.For improving efficiency of transmission, each interface single plate can be broadcasted the data from the master control veneer to the low speed bus that self connects, and each veneer to be downloaded that step 204 is determined can receive broadcast data from low speed bus.Because all low speed veneers that are connected on the low speed bus can receive broadcast data, and be not the low speed veneer that is connected on the low speed bus all be current veneer to be downloaded.So can be each low speed veneer state is set, each low speed veneer can determine whether to receive the data of broadcasting on the bus according to oneself state, such as: the initial condition that each low speed veneer is set is an idle condition, when the low speed veneer successfully receives claim frame, when returning response, oneself state is changed to the preparation accepting state, and the low speed veneer that does not successfully receive claim frame keeps idle condition; Then, when each interface single plate during respectively to data that the low speed bus broadcast reception that self connects is arrived, current for the low speed veneer of preparing accepting state will receive the data of this low speed bus broadcasting, and current be that the low speed veneer of idle condition will be rejected the data that this low speed bus is broadcasted.
Step 206: after veneer receives data, will return response and give master control veneer, master control veneer receives the response from each veneer to be downloaded of current selected type, thereby whether the data that determining step 205 sends are received by each veneer, when determining to have been received by each veneer, execution in step 207.
Here, master control veneer will continue to receive the response from each veneer to be downloaded of current selected type, when the response of all veneers to be downloaded that receive current selected type, can determine that just the Data Receiving of each veneer to be downloaded of current selected type finishes, and then execution in step 207.
Step 207: whether also have non-selected type in each board type that master control veneer determining step 201 is collected, if then return step 202; Otherwise finish current handling process.
In the above-mentioned flow process, can use the sign of veneer to determine whether the veneer of current selected type, veneer to be downloaded and the transfer of data of current selected type veneer finish or the like.Be exactly specifically: what step 201 was set up can be the sign of each veneer and the corresponding relation of board type, so in the step 203, master control veneer can be determined the sign of each veneer of current selected type, set up the veneer sign tabulation of current selected type, and send claim frame to each veneer by each veneer sign in this tabulation.And in step 204, each veneer that successfully receives claim frame can carry self identification in the response of being returned, thereby master control veneer can be determined current veneer to be downloaded according to the veneer sign in each response that receives, and sets up current single board list to be downloaded.Subsequently in step 206, each receives in the response that veneer returned of data and carries self identification, thereby in the step 207, the veneer sign that master control veneer can carry each response that receives, compare with each veneer sign in the single board list of being set up current to be downloaded, thereby whether the transfer of data of determining the current type veneer finishes.
The inventive method can be applicable in the access network equipment of 2G or 3G network, and when this method was applied to the 2G network, described access network equipment was BTS or BSC; When this method was applied to 3G network, described access network equipment was base station node B or RNC.
According to the described flow process of above Fig. 2 as seen, under the prerequisite of transferring large number of data, the download of finishing a class low speed veneer should approximate required average time finishes T average time that veneer is required, if three class low speed veneers are arranged, then finishing and downloading required total time is 3T.And as can be known according to background technology, adopt between existing first kind of plate transmission method finish three classes the transfer of data required time of totally 8 low speed veneers be 8T.As seen, download time has reduced 5T behind application the present invention, and efficiency of transmission has then improved 167%.The inventive method not only can significantly improve efficient in the transfer of data of low speed veneer, can obtain identical beneficial effect equally in the transfer of data of high speed veneer.
In sum, the inventive method can significantly improve efficiency of transmission between plate, is particularly suitable for using in construction, maintenance and the dilation process at access network equipment, with the transmission of efficient realization mass data between a large amount of veneers.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.All any modifications of being done within the spirit and principles in the present invention, be equal to replacement, improvement etc., all be included in protection scope of the present invention.
