UE, 3GPP network access equipment or WLAN access device are after the second load of the first load and WLAN that get 3GPP access network, can according to the first load and the second load, shunting process is carried out between 3GPP access network and WLAN to data to be sent, specifically by comparing the first load and the second load and pre-determined threshold, can determine data distribution to be sent to 3GPP access network or WLAN.
The shunting anchor point of prior art is usually in core net, as packet data network gateway (PDN Gateway, be called for short PGW) or Gateway GPRS Support Node (Gateway GPRS Support Node, be called for short GGSN), because core network element cannot obtain the information of eating dishes without rice or wine in time, therefore taked distributing strategy, as shunt ratio etc. can not adjust in real time with the situation of eating dishes without rice or wine of 3GPP access network and WLAN side, when certain side eat dishes without rice or wine occur congested or channel quality changes time, still adopt this semi-static ratio will produce the inefficient problem of data distribution.
The data distribution processing method that the present embodiment provides, the first load and the second load is obtained by UE, 3GPP network access equipment or WLAN access device, again according to the first load and the second load, shunting process is carried out between 3GPP access network and WLAN to data to be sent, situation of the eating dishes without rice or wine dynamic conditioning shunt ratio in time according to 3GPP access network and WLAN side can be realized, and then improve the efficiency of data distribution.

Specifically, if WLAN supports IEEE802.11e, in 802.11e revision, an expansion is carried out, in order to the service quality (QoS) of tenaculum priority to basic distributed coordination function (Distributed Coordination Function is called for short DCF).Distributed channel access (Enhanced Distributed Channel Access, being called for short EDCA) mechanism defines (the Access category of access style in 4, be called for short AC), be respectively AC_BK, AC_BE, AC_VI and AC_VO, its priority according to this from low to high, each AC is defined by the specific assignment of a group of access parameter, these parameters statistically define the priority of each AC to channel access, under EDCA, export-oriented communication is ranked into 4 queues by logic, each corresponding AC.The queue of each non-NULL runs an EDCA access function to realize contention access by the access parameter of this AC, so UE obtains the load that can obtain the minimum buffer queue of buffer queue medium priority corresponding to WLAN, and the busy-idle condition of WLAN is determined by the load and pre-determined threshold of comparing the minimum buffer queue of buffer queue medium priority corresponding to WLAN, consider that if the Buffer of the data corresponding A C of high priority expired main here, can fill in the queue of low priority in the past, if therefore AC_BK has expired and illustrates that WLAN side is without available Buffer.

If S302 first load is greater than the first pre-determined threshold and the second load is less than the second pre-determined threshold, then transmit in data distribution to be sent to WLAN.
Be understandable that, if the first load is less than the first pre-determined threshold, does not then need to carry out shunting process to current data to be sent, if the second load is greater than the second pre-determined threshold, then show that the Buffer state of WLAN side is busy (BUSY).
Alternatively, transmit in data distribution to be sent to WLAN, can comprise:
Determine the access style of data to be sent;
Data to be sent are linked into buffer queue corresponding to access style.
Fig. 4 is the principle schematic of data distribution processing method embodiment three provided by the invention, as shown in Figure 4, in the present embodiment, 3GPP network access equipment is for eNB, WLAN access device is AP, UE0 and UE1 corresponding carrying DRB0 and DRB1 meeting draining conditions respectively of draining conditions is met in the present embodiment, can judge whether UE and carrying meet draining conditions according to the subscription data of UE and type of service, in the present embodiment, in WLAN, AP can comprise 4 buffer queues corresponding to 4 kinds of access styles, the buffer load of UE0DRB0 and UE1DRB1 exceedes presets shunting thresholding, determine to need data to be sent to be sent in WLAN, first according to the UE and the loading priority that arrive packet, determine the AC type that this packet is linked into.If the queue of this AC is full, be then linked into the queue of low one-level priority AC, the packet of UE0DRB0 is linked into the buffer queue that AC type is VO by the present embodiment, and the packet of UE1DRB1 is linked into the buffer queue that AC type is VI.
Wherein, the AC type for the data being diverted to WLAN judges there is the following two kinds implementation:

It may be noted that above just two kinds of possible mapping implementation, can adopt other mapping mode during specific implementation, the present embodiment is not as limit.
If S303 second load is greater than the 3rd pre-determined threshold, then determine the data turnover speed difference of WLAN, data turnover speed difference is the difference of the data rate of input WLAN and the data rate of output WLAN.
S304, data backflow to be sent to be transmitted to 3GPP access network, until data turnover speed difference is less than or equal to zero.
Specifically, after data to be migrated to be branched in WLAN transmission, if the second load is greater than the 3rd pre-determined threshold, namely WLAN side Buffer exceedes pre-determined threshold, then the Buffer state of WLAN is set to BUSY, and calculate data turnover speed difference (Rate Gap) of WLAN side, business is back to 3GPP access network according to priority.
Judge that object that whether second load of WLAN is greater than the 3rd pre-determined threshold avoids, when the load of WLAN side is high, still having the data of new carrying correspondence to be divided to WLAN.The object of data backflow is, when the message transmission rate of WLAN side cannot support the carrying being diverted to WLAN, by the data backflow of part carrying to 3GPP access network.
Only have the Rate Gap that just can calculate WLAN under the Buffer of WLAN is in BUSY state, Rate Gap represents when the difference that advance into the data rate of WLAN and WLAN air interface transmission speed (be generally on the occasion of).After the Buffer of WLAN is in BUSY state, although the data rate entering WLAN can not continue to increase, Buffer may be measured owing to exceeding transmittability that current WLAN eats dishes without rice or wine and continue to increase, and finally cause WLAN side Buffer to overflow.
Therefore, after the Buffer of WLAN is in BUSY state, carry out periodic statistics to the speed difference of entry/exit Buffer in real time, statistical method is as follows:
Rate?Gap=[N(t+Period)-N(t)]/Period
Wherein, N is the buffer memory of Buffer, and t is statistics initial time, is the moment t just having entered BUSY state when first time calculates, and n-th time is t+n*Period later, and Period is the measurement period of Rate Gap.
After calculating Rate Gap, according to the priority shunting carrying, according to the order of sequence the carrying being diverted to WLAN is switched back to 3GPP access network, reduce the data volume being diverted to WLAN side, until the Rate Gap<=0 of WLAN side.
After data backflow to 3GPP access network, the Buffer of 3GPP side may continue to increase, if again more than the first pre-determined threshold, the shunting request now sent may be rejected, along with the continuation of Buffer increases, the mechanism such as the congestion packet loss of 3GPP side, rear end speed limit can be triggered.
The data distribution processing method that the present embodiment provides, by the first load of acquisition 3GPP access network and second load of WLAN, if the first load is greater than the first pre-determined threshold and the second load is less than the second pre-determined threshold, then transmit in data distribution to be sent to WLAN, if the second load is greater than the 3rd pre-determined threshold, then determine the data turnover speed difference of WLAN, and data backflow to be sent is transmitted to 3GPP access network, until data turnover speed difference is less than or equal to zero, situation of the eating dishes without rice or wine dynamic conditioning shunt ratio in time according to 3GPP access network and WLAN side can be realized, and then improve the efficiency of data distribution.
