Problems solved by technology

[0010] However, in the existing HSDPA multi-stream technology, it is difficult for the RNC to determine how much data to be sent should be allocated to each tributary. Moreover, the RNC cannot know the actual maximum capacity of each tributary, so the effective application of the HSDPA multi-stream technology cannot be realized.

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...

Abstract

Provided are an optimization method and system for a multi-stream of high-speed downlink packet access (HSDPA). The method comprises: a radio network controller (RNC) sending to each NodeB participating in an HSDPA multi-stream a message comprising information on the NodeB itself about the total amount of data to be sent; each NodeB judging whether a user receiving data to be sent by the RNC is a multi-stream user of an assisting cell or not, if the user is a multi-stream user of an assisting cell, feeding back to the RNC the amount of data to be sent of a single-stream user in the cache of the assisting cell which is calculated statistically in advance; and according to the amount of data to be sent of the single-stream user which is fed back by each NodeB and the resource allocation condition fed back by each NodeB, the RNC streaming the data to be sent to the NodeBs. Also provided are an RNC and a NodeB. For an HSDPA multi-stream user streaming among NodeBs, the present invention streams data to be sent by requesting the maximum data sending capability to each NodeB according to the amount of data to be sent of a single-stream user of an assisting cell, thereby improving the user experience while balancing the system fairness, so as to achieve the effective application of HSDPA multi-streaming.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a high-speed downlink packet access (Dual Cell-High Speed ​​Downlink Packet Access, HSDPA) multi-flow optimization method, system and device. Background technique [0002] With the continuous and rapid development of data services, High Speed ​​Packet Access (HSPA) technology is becoming more and more common, and it is developing towards the direction of multi-antenna and multi-carrier. For example, the R7 version of 3GPP introduced the MIMO ( Multiple Input Multiple Output (MIMO) technology enables the base station (NodeB) to simultaneously send two transport blocks from the same cell to the user equipment (User Equipment, UE) through dual antennas; subsequently, the R8 version of 3GPP introduced dual-cell HSDPA technology , so that the NodeB can send HSDPA data to the UE from two frequency points of two adjacent cells at the same time. The above two technologies g...
