It is described in detail exemplified by controller.
Embodiment one
It should be noted that a kind of transmission method of business datum provided in an embodiment of the present invention is to be based on Fig. 1
What shown framework was realized.It is that user is sent out by UE to network side in the application premise of the embodiment of the present invention
When sending the corresponding business datum of business, the business datum is the data existed in wireless caching server,
That is cache hit.
The embodiments of the invention provide a kind of transmission method of business datum, as shown in Fig. 2 this method can be with
Including：
S101, when UE and wireless caching server carry out business data transmission corresponding with business, detect
Whether the UE carries out the switching from source base station to target BS.
It should be noted that UE to network side send a business corresponding business datum when, a business
In may include multiple objects, so, when UE asks the business datum of a business to network side, be
Send corresponding request message to realize the download of the corresponding business datum of each object or obtain according to each object
Take.
Specifically, UE can send the corresponding request message of first object to source base station, the source base station passes through
Content sinking controller obtains the business number of first object of UE requests from wireless caching server
According to.
It should be noted that when UE business data transmissions corresponding with business with the progress of wireless caching server
When, it is possible that due to the UE reason such as mobile, the UE needs to be switched to target base from source base station
Situation about standing occurs.Once there is such situation, the biography that UE passes through the ongoing business datum of source base station
The occurrence of defeated flow can change to adapt to above-mentioned.
Specifically, when UE carries out business data transmission corresponding with business with wireless caching server, it is interior
Hold heavy server can detect first the UE whether carrying out switching from source base station to target BS or
It is that will carry out the switching from source base station to target BS, so that the content sinking controller carries out corresponding industry
The adjustment for data transfer of being engaged in.I.e., in embodiments of the present invention, whether content sinking controller detects the UE
Carrying out the switching from source base station to target BS includes two kinds of implications：One kind is that the detection of content sinking controller is
The no switching carried out from source base station to target BS；It is another be content sinking controller detect whether by
Occurs the switching from source base station to target BS.
Further, (1), detect whether to carry out from source base station to target base for content sinking controller
The switching stood, is specifically as follows：Content sinking controller detects whether to receive handover request, and the switching disappears
In the switching request acknowledgement message that the request handover request and target BS that breath includes source base station transmission are sent extremely
Few one kind；If receiving handover request, sign detects that UE carries out cutting from source base station to target BS
Change；If not receiving handover request, sign detects that UE does not carry out cutting from source base station to target BS
Change.(2) switching by generation from source base station to target BS, tool, are detected whether for content sinking controller
Body can be：According to the first parameter, the first of switchings of the UE by progress from source base station to target BS is calculated
Probability, first parameter is UE performance parameter；When the first probability is more than or equal to pre-determined threshold, detection
Go out switchings of the UE by generation from source base station to target BS；When the first probability is less than pre-determined threshold, detection
Switching from source base station to target BS will not occurred by going out UE.
It should be noted that because handover request can include request handover request and target that source base station is sent
At least one of switching request acknowledgement message that base station is sent；Therefore, content sinking controller, which is received, cuts
Change message and refer to that the content sinking controller is received in above-mentioned request handover request and switching request acknowledgement message
At least one, and the content sinking controller do not receive handover request refer to be not received by it is above-mentioned
Ask any one in handover request and switching request acknowledgement message, i.e., above-mentioned request handover request and switching
The meaning that request confirmation message one is all not received by.
Further, content sinking controller can monitor the signaling that source base station is received and dispatched by DPI functions, work as inspection
Measure after handover request or switching request acknowledgement message, can confirm that corresponding UE is switched over.Except this it
Outside, content sinking controller can also send out the sinking of message informing content by source base station when UE switches and control
Device processed.The concrete implementation mode embodiment of the present invention is not restricted.
Specifically, in the embodiment of the present invention, source base station can avoid UE cutting as far as possible by switching anticipation
Still in the situation from wireless caching server downloading data when changing.Source base station calculates UE according to the first parameter
By the first probability of switching of the progress from source base station to target BS.When the first probability is less than pre-determined threshold,
Source base station sends a notification message to content sinking controller, so that content sinking controller detects UE
To occur switching from source base station to target BS, wherein, the notification message be used to characterizing UE will occur from
Switching of the source base station to target BS.When the first probability is more than or equal to pre-determined threshold, source base station does not send logical
Message is known to content sinking controller, so that content sinking controller does not detect that UE will occur from source
Switching of the base station to target BS.
Optionally, the first parameter includes：The position letter of UE signal quality, UE translational speed and UE
At least one of breath.
In detail, (1), UE signal quality.UE signal quality reports acquisition by measurement, passes through
Measurement result estimates the probability size that will be switched with the difference Delta of switch decision thresholding.UE letter
The related switching probability P_sig of number quality is piecewise function, as follows：
Wherein, the usual value 1dB of the usual value 5dB of Thred_sig_high, Thred_sig_low, and can
With experience adjustments.
Exemplary, it is assumed that the blind handover judgment condition of the cell-of-origin where UE is Reference Signal Received Power
(RSRP, Reference Signal Receiving Power)<- 110dBm, then switch decision thresholding is -110.
The RSRP obtained when UE measurements>During -104dBm, then it is assumed that UE switching probabilities are 0, when UE is measured
To RSRP be<During -109dBm, it is believed that UE will switch, switching probability is 100%.
, can be according to it should be noted that the form embodiment of the present invention of switch decision thresholding is not restricted
Practical application is realized.For example：If the switch decision condition of the cell-of-origin where UE is neighboring area signal intensity
3dB (considering the factors such as switching sluggishness) higher than local area signal intensity, then switch decision thresholding is 3dB, when
During the high 2dB of neighboring area signal strength ratio local area signal intensity that UE measurements are obtained, it is believed that UE will switch,
Switching probability is 100%, and remaining is similar.
(2), UE translational speed.UE translational speed Speed passes through UE history handover information or many
General Le frequency displacement measurement is obtained, and specific measuring method is existing prior art, is not discussed herein.Consider measurement
The factors such as precision, by UE translational speed be simply divided into low speed, two grades of non-low speed (specific thresholding
Setting can be determined according to the situation of actual use, and the embodiment of the present invention is not restricted).Specifically, UE shifting
The switching probability P_speed of dynamic velocity correlation is piecewise function, as follows：
(3), UE positional information.UE positional information can be obtained based on location algorithm, be simply divided into
Cell edge and the class of non-cell edge two.The related switching probability P_pos of UE positional information is piecewise function,
It is as follows：
It can thus be concluded that：Final UE switching probability P=P_sig*W 1+P_speed*W 2+P_pos*W 3.
W 1, W 2, W 3 respectively UE signal quality, UE translational speed, UE positional information correspondence
Weights, W 1+W 2+W 3=1.The usual values 0.6 of W 1, W 2 the values 0.2 of W 3.
Then, when P is less than pre-determined threshold, it is believed that UE will not switch, and then source base station is not made to locate
Reason；When P is more than or equal to pre-determined threshold, it is believed that UE will switch, and source base station notifies to hold to interior
Heavy controller, content sinking controller made suspends it and uses wireless caching function.
Optionally, the acquiescence value of pre-determined threshold can be 50%, the setting of the numerical value of specific pre-determined threshold,
The embodiment of the present invention is not restricted.
It should be noted that because the first parameter in embodiments of the present invention can include：UE signal matter
At least one of positional information of amount, UE translational speed and UE.Therefore, when on the first parameter only has
When stating the partial parameters in three kinds of parameters, UE switching probability according to partial parameters just by calculating obtained probability
To realize.
It is preferred that, the first parameter in the embodiment of the present invention only includes UE signal quality.So, preset
Thresholding is exactly the switch decision thresholding of the judgement probability related to UE signal quality, and UE switching probability is just
It is P_sig.
Further, the type of the first parameter in the embodiment of the present invention is not restricted, as long as can be to UE
Pre- judgement is made in the switching that will occur.
S102, when detecting UE and carrying out switching from source base station to target BS, forbid first pair of transmission
The first service data request message of elephant is sent to wireless caching server, and by first business request information
To core net, to carry out the transmission of the first business datum, wherein, first object is not carry out business number also
According to the object of transmission, this is wireless, and caching server is corresponding with source base station.
Whether content sinking controller detection UE is carried out after the switching from source base station to target BS, works as inspection
When measuring switching of the UE progress from source base station to target BS, the content sinking controller forbids transmission first
First service data request message of object is sent out to wireless caching server, and by first business request information
Core net is delivered to, to carry out the transmission of the first business datum, wherein, first object is not carry out business also
The object of data transfer, this is wireless, and caching server is corresponding with source base station.
It should be noted that due in UE business datums corresponding to one business of network side transmission, being somebody's turn to do
Multiple objects may be included in one business, so, UE asks the business number of a business to network side
According to when, be to send corresponding request message to realize the corresponding business datum of each object according to each object
Download or obtain.Therefore, when UE can send the corresponding request message of first object to source base station,
The source base station obtains this first of UE requests by content sinking controller from wireless caching server
After the business datum of object, the UE can proceed by the corresponding request message of second object, to obtain
Take the corresponding business datum of second object.
Whether will be switched it should be noted that the source base station where UE can shift to an earlier date the anticipation UE,
When judging that the UE is likely occurred switching, the source base station content of announcement sinking controller, to cause this interior
Holding heavy controller can suspend using the function of wirelessly caching.In embodiments of the present invention, in spite of slow
Hit is deposited, the new object request message of UE requests all will pass through core net by core net, by core
Heart net provides service, but the transmission for the object downloaded from wireless caching server is unaffected, i.e.,
Pause caching only influences the download of new object.
The first object in the embodiment of the present invention refers in a business of the UE requests for being and does not start what is asked
One class object.
Exemplary, when user opens a Photo Browser, due to the possibility in the Photo Browser
8 pictures are contained, the mobile phone first sends the request messages of the first pictures to wireless caching server, this
Sample, other pictures in addition to first pictures do not start to carry out the request of image content also, therefore,
Other 7 pictures can be the first object in the embodiment of the present invention.
S103, when switchings of the UE from source base station to target BS is completed, if in the presence of the not be transmitted
Two business datums, then control continues to send second business datum to source base station, and second business datum is UE
The business datum of the second object transmitted in the switching from source base station to target BS.
When switchings of the UE from source base station to target BS is completed, if in the presence of the second business not being transmitted
Data, i.e., when also the second business datum is not obtained from wireless caching server, then content sinking controller
Transmission flow will be controlled, second business datum is continued to send to source base station, so that the source base station passes through
Target BS is by second business data transmission to UE.
Exemplary, when user opens a Photo Browser, due to the possibility in the Photo Browser
8 pictures are contained, the mobile phone first sends the request message of first picture to wireless caching server,
Mobile phone is also during the content of the first pictures is obtained, if the mobile phone will be carried out from source base station to target base
During the switching stood, it is second in the embodiment of the present invention that this, which carries out obtaining the first pictures of image content,
Object, the image content of first pictures is the corresponding business datum of the second object.
It should be noted that because source base station is obtained from wireless caching server by content sinking controller
Corresponding second business datum of second object, therefore, the content sinking controller can be from wireless buffer services
The total size of second business datum is known in device, and the second business datum transmitted size.Separately
Outside, in the transmitting procedure of above-mentioned second business datum, source base station is cached by content sinking controller from wireless
It is to transmit preset byte according to each when obtaining the second business datum in server, it is just complete by being transmitted several times
Into.The wireless caching server of source base station can not be accessed after target BS because UE is switched to, to avoid
The interruption of business, accordingly, it would be desirable to which source base station is surplus by the whole of the downloaded object not yet passed (the second object)
Remaining content is all switched to target BS.And due to transmission control protocol (TCP, Transmission Control
Protocol) there is window limit, the second business number of a preset byte is transferred in wireless caching server
According to rear, wireless caching server needs to receive ACK (Acknowledgement) the feedbacks just meeting of source base station
Continue to send remaining second business datum, and UE is switched to after target BS, source base station is obtained less than UE
Acquisition feedback information when, also will not by ACK feedback bag (confirmation packet) arrive wireless caching server,
In this way it is possible to cause the wireless caching server due to not receiving the ACK after last be transmitted
Feedback is without may proceed to remaining second business datum of transmission, so that source base station can not obtain complete remain
Corresponding second business datum of second object of remaininging.For such situation, in the embodiment of the present invention in hold
Heavy controller can construct ACK feedbacks bag after switching occurs by simulating UE, and (commonly referred to as rehearse ACK
Bag) wireless caching server is issued, so as to avoid TCP window from limiting, it can allow wireless caching server will
Corresponding remaining second business datum of second object continues through content sinking controller and is sent to source base station.
Therefore, specifically, when switchings of the UE from source base station to target BS is completed, if in the presence of not transmitting
The second business datum completed, then control continuation sends the second business datum to the source base station and included：If in the presence of
The second business datum not being transmitted, then send and confirm packet (ACK feedbacks bag) to wireless caching clothes
Business device, this is wireless, and caching server continues to send the second business datum to source base station according to confirmation packet, should
Source base station by target BS by second business data transmission to UE, second business datum be UE from
Source base station to target BS switching when the business datum of the second object transmitted.
Optionally, preset byte can be 1000 bytes, and the big I of specific preset byte is according to actual feelings
Condition is determined, and the embodiment of the present invention is not restricted.
It should also be noted that, due to the first object correspondence that in above-mentioned data reversed process, UE is asked
The first business datum be that gateway is obtained by service server and is sent to source base station, therefore, the source base station
