Embodiment 1
[0117] Embodiment 1: NodeB1 meets the preset air interface rate threshold, and NodeB2 does not meet the preset air interface rate threshold.
[0118]Step 1, the RNC receives the user data of the UE from the CN and puts it into the buffer, and the total amount of user data is Y1 bytes;
[0119] Step 2, RNC sends HS-DSCH capability request frames to NodeB1 and NodeB2 respectively, where User BufferSize fills in Y1bytes;
[0120] Step 3: NodeB1 allocates an air interface rate of 36M for the corresponding priority queue according to the size of the data to be sent, buffer size, and air interface capacity, and feeds back to RNC1 through the HS-DSCH capacity allocation frame;
[0121] Step 4: NodeB2 allocates an air interface rate of 16M for the corresponding priority queue according to the amount of data to be sent, buffer size, and air interface capability, and feeds back to RNC1; at the same time, feeds back to RNC1 the current single-stream users of CELL2 and the multi-stream of...
Embodiment 2
[0123] Embodiment 2: NodeB1 does not meet the preset air interface rate threshold, and NodeB2 meets the preset air interface rate threshold.
[0124] Step 1, RNC1 receives UE1's user data from CN1 and puts it into the buffer, the total amount of user data is Y1bytes;
[0125] Step 2, RNC1 sends HS-DSCH capability request frames to NodeB1 and NodeB2 respectively, where User BufferSize fills in Y1bytes;
[0126] Step 3: NodeB1 assigns an air interface rate of 12M to the corresponding priority queue according to the size of the data to be sent, buffer size, and air interface capability, and feeds back to RNC1 through the HS-DSCH capability allocation frame;
[0127] Step 4: NodeB2 assigns an air interface rate of 36M to the corresponding priority queue according to the size of the data to be sent, the buffer size, and the air interface capacity, and feeds back to RNC1; at the same time, feeds back to RNC1 the current single-stream users of CELL2 and the multi-stream of the servin...
Embodiment 3
[0133] Embodiment 3: Neither NodeB1 nor NodeB2 meets the preset air interface rate threshold.
[0134] Step 1, RNC1 receives UE1's user data from CN1 and puts it into the buffer, the total amount of user data is Y1bytes;
[0135] Step 2, RNC1 sends HS-DSCH capability request frames to NodeB1 and NodeB2 respectively, where User BufferSize fills in Y1bytes;
[0136] Step 3: NodeB1 assigns an air interface rate of 12M to the corresponding priority queue according to the size of the data to be sent, buffer size, and air interface capability, and feeds back to RNC1 through the HS-DSCH capability allocation frame;
[0137] Step 4, NodeB2 allocates an air interface rate of 20M for the corresponding priority queue according to the size of the data to be sent, the buffer size, and the air interface capability, and feeds back to RNC1;
[0138] Step 5, RNC1 judges that the air interface rate of NodeB1 does not meet the preset air interface rate threshold, that is, 12M<40M*0.8, and the a...
