It should be noted that " predefined " in the embodiment of the present invention can be pre-configured in the network equipment and UE In, can be notified after the network equipment is determined by high-level signaling to UE, the embodiment of the present invention This is not construed as limiting.
Fig. 2 is the flow chart of the method for the data transfer of the embodiment of the present invention.Show that network is set in Fig. 2 Standby 22 and UE 24.Method shown in Fig. 2 comprises the following steps：
S202, the network equipment 22 receives the uplink random access request signal that at least one UE is sent.
Wherein, at least one UE includes UE 24.
Specifically, what the network equipment 22 received that at least one UE sends respectively in very first time window is up Random access request signal.
For example, for UE 24, before UE 24 needs to send upstream data to the network equipment 22, Can be in very first time window to the transmission uplink random access request signal of the network equipment 22.
Alternatively, uplink random access request signal can be PRACH, or, or detection Reference signal (Sounding Reference Signal, SRS), the embodiment of the present invention is not construed as limiting to this.
S204, the network equipment 22 counts the uplink random access request signal received in very first time window Quantity.
Specifically, statistics sends uplink random access request to the network equipment 22 in very first time window and believed Number at least one UE quantity.
It is understood that in S204, at least one UE includes UE 24.
It is succinct for description, UE 24 is merely illustrated in Fig. 2, removed at least one UE UE 24 it Process performed by outer other UE is similar with the process performed by UE 24, no longer retouches in detail here State.
As one, as shown in Figure 3, it is assumed that each time window includes 10 subframes.So, network is set Standby 22 can count the quantity of at least one UE in very first time window as shown in Figure 3.Wherein, Upward arrow can represent the uplink random access request signal that the network equipment 22 is received in Fig. 3.
S206, the network equipment 22 is according to the quantity in the S204 UE counted, it is determined that load is indicated Information.
Specifically, the network equipment 22 can first obtain predefined access request grade of load relation；And root According to the access request grade of load relation, it is determined that the grade of load corresponding with above-mentioned quantity；Further will The corresponding grade of load is used as the load instruction information.
Alternatively, before S206 or even before S202, access request load etc. can first be predefined Level relation.For example, the access request grade of load relation can be prestored in the network equipment 22.
The access request grade of load relation includes corresponding between the UE of access quantity and the grade of load Relation, can be as shown in Table 1 as one.

.....
2 51-150
1 0-50
For example, if determining the uplink random access request received in very first time window in S204 The quantity of signal is 102, then by searching access request grade of load relation, it may be determined that load etc. Level is 2, and then can determine that the load instruction information in S206 is 2.For example load can be indicated letter Breath is expressed as lOI, lOI=2.
Furthermore it is possible to which the maximum of the grade of load in access request grade of load relation is expressed as into LOI。 For the access request grade of load relation shown in table one, LOI=10.
Wherein, the maximum of the grade of load is used for the quantity institute energy for indicating total RB of uplink data channels The maximum of the quantity of the user equipment enough carried.That is, when the quantity of the user equipment of access reaches To the grade of load maximum when, in uplink, it is necessary to use all RB of uplink data channels.
It is understood that according to predefined access request grade of load relation, just can therefrom obtain load etc. The maximum of level.
S208, the network equipment 22 sends load instruction information to UE 24.
It is understood that load instruction information is corresponding with very first time window.The load instruction information is used to indicate The quantity for the uplink random access request signal that the network equipment 22 is received in very first time window.Or, It is properly termed as, load instruction information is the load instruction information in very first time window.
Alternatively, load instruction information can be sent at least one UE by the network equipment 22, wherein extremely A few UE is included at least one UE counted in S204.
Alternatively, the network equipment 22 can send load instruction information in the form of broadcasting.
Alternatively, the network equipment 22 can send load instruction information by down control channel.For example, By down control channel carry load configured information lOI.For example, down control channel can be by with first The mode of the OIRNTI scramblings of the numbering correlation of time window, sends the load instruction information.Wherein, The numbering of one time window can be expressed as nw1, i.e. OIRNTI=nw1。
It is understood that in S208, the network equipment 22 be a certain moment after the first timing window (for example For the t0 moment), send the load instruction information.
Correspondingly, UE 24 should be after the first timing window a certain reception load instruction information.
It is alternatively possible to which predefined timing relationship, timing relationship is used to represent to receive load instruction information The difference between very first time window when downlink reception moment and transmission uplink random access request signal.Its In, the difference can be a specific value or the difference can be an interval.
Assuming that the finish time of very first time window is labeled as t1, if the difference that timing relationship is represented is Δ t, So UE 24 can determine that the downlink reception moment is t1+ Δ t, and then, UE 24 can be in the downlink reception Carve and receive the load instruction information that the network equipment 22 is sent.
Assuming that the finish time of very first time window is labeled as into t1, if the difference that represents of timing relationship for Δ t1~ Δ t2, then UE 24 can receive network and set at downlink reception moment, i.e. interval t1+ Δs t1~t1+ Δ t2 Standby 22 load instruction informations sent.That is, what if timing relationship represented is an interval, that The load instruction information that any times of the UE in the interval at corresponding downlink reception moment receives is all Will be considered that be very first time window load instruction information.
Assuming that the numbering of last subframe of very first time window is n, if the difference that timing relationship is represented is k Individual subframe, then UE 24 can determine that the downlink reception moment is n+k subframes, and UE 24 is in the n-th+k Subframe receives the load instruction information that the network equipment 22 is sent.
That is, UE 24 can by the numbering of last subframe of very first time window and difference sum, It is used as the numbering of the subframe at downlink reception moment.
It should be noted that as one, k can be a value, or k can also be the set of multiple values. If k value is 1 to 5 set, then, UE 24 connects in the subframe interval that numbering is n+1 to n+5 Receive load instruction information.
