Description

Method, system and device for optimizing high-speed downlink packet access multi-stream
Technical Field
The present invention relates to the field of wireless communications, and in particular, to a method, a system, and an apparatus for optimizing a High Speed Downlink Packet Access (HSDPA) multi-stream.
Background
With the continuous and rapid development of data services, a High Speed Packet Access (HSPA) technology is more and more common, and is developed in the direction of multi-antenna multi-carrier, for example, a Multiple Input Multiple Output (MIMO) technology is introduced into R7 version of 3GPP, so that a base station (NodeB) can simultaneously transmit two transport blocks from the same cell to a User Equipment (UE) through dual antennas; subsequently, the R8 version of 3GPP introduced a dual-cell HSDPA technology, so that the NodeB could send HSDPA data to the UE from two frequency points of two neighboring cells at the same time. The two technologies greatly improve the data throughput of the cell.
When the UE is located at the edge of two cells with the same frequency and performs soft handover or updates soft handover, the air interface capability of a serving High Speed-Downlink Shared Channel (HS-DSCH) cell is often limited, but a non-serving HS-DSCH cell in an active set also has available resources, and if data can be sent to the UE from the non-serving cell at the same time, user experience is greatly improved, thereby improving the data throughput of the cell. Therefore, release R11 of 3GPP started to discuss the multi-stream technique of HSDPA.
With the discussion of HSDPA multi-flow technology by 3GPP, in addition to the above-mentioned UE can receive data of two cells with the same frequency at the same time, the UE can also receive data of at most four cells with two frequency points at the same time. Wherein, one cell on the main carrier frequency is called a serving HS-DSCH cell (serving HS-DSCH cell), and the other cell is called an assisting serving HS-DSCH cell (assisting serving HS-DSCH cell); one cell on the secondary carrier frequency is called a secondary serving HS-DSCH cell (secondary serving HS-DSCHcell) and the other cell is called an assisting serving HS-DSCH cell (assisting secondary serving HS-DSCH cell). The specific HSDPA multiflow configuration is shown in table 1:
Figure BDA00002135170200021
TABLE 1
For convenience of description, the serving HS-DSCH cell and the secondary serving HS-DSCH cell are collectively referred to as a serving cell, and the assisting serving HS-DSCH cell and the assisting secondary serving HS-DSCH cell are collectively referred to as an assisting cell.
According to the division of the divided base stations, the HSDPA multi-flow technology is divided into intra-NodeB division and inter-NodeB division. For the inter-NodeB offloading, the 3GPP conference determines that user data is offloaded on a Radio Link Control (RLC) layer, and needs a Radio Network Controller (RNC) to periodically send an HS-DSCH capability request to each NodeB, and offloads RLC data to different Node bs according to capability conditions fed back by each NodeB. Here, since the load and the delay of each NodeB are different, the shunting between nodebs may cause the RLC data with a large sequence number to arrive at the UE before the RLC with a small sequence number, thereby causing a "SKEW" phenomenon, which affects the data throughput. Therefore, when the RNC schedules data, the shunting can be avoided as much as possible according to the actual maximum capacity of the Node B.
In addition, in the HSDPA multi-flow technology, a multi-flow user actually occupies flows of a conventional user and other single-flow users, thereby affecting fairness of the entire system. Therefore, when the RNC schedules data, if the data volume of the conventional user and other single-stream users in the assisting cell is large, the data of the multi-stream user can be scheduled to the serving cell to be sent as much as possible according to the actual maximum capacity of the serving cell.
However, in the existing HSDPA multiflow technique, it is difficult for the RNC to determine how much data to be transmitted should be allocated to each tributary, and the RNC cannot know the actual maximum capacity of each tributary, and cannot implement effective application of the HSDPA multiflow technique.

Detailed Description
The basic idea of the invention is as follows: RNC sends message containing total data volume to be sent to each NodeB participating HSDPA multi-flow; each NodeB judges whether a user receiving the data to be sent by the RNC is a multi-flow user of an assisting cell, and feeds back the pre-counted data volume to be sent of a single-flow user in the cache of the assisting cell to the RNC when the user is the multi-flow user of the assisting cell; and the RNC distributes the data to be transmitted to each NodeB according to the data volume to be transmitted of the single-flow user fed back by each NodeB and the resource distribution condition fed back by each NodeB.
The assisting cells include assisting serving HS-DSCH cells and/or assisting secondary serving HS-DSCH cells. The single-stream user refers to a user that can only receive data of one HS-DSCH cell at the same time, and specifically includes a conventional user that does not support HSDPA multi-streaming and a multi-streaming user that supports HSDPA multi-streaming but is in a single-stream state.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings by way of examples.
Fig. 1 is a flow of implementing the HSDPA multiflow optimization method of the present invention, and as shown in fig. 1, the method includes the following steps:
step 101, RNC sends message containing total data volume to be sent to each NodeB participating HSDPA multi-flow;
in this step, the total data volume to be transmitted of the RNC is the sum of the data volumes to be distributed to the corresponding priority queues of the respective nodebs;
specifically, the RNC transmits an HS-DSCH capacity request frame or an HS-DSCH data frame including its total amount of data to be transmitted to each NodeB participating in HSDPA multiflow;
here, a Common Transport Channel Priority Indicator (CmCH-PI) in the structure of the HS-DSCH capability request frame is a Priority Indicator of a corresponding Priority queue, and the User Buffer Size is used to carry total data volume information to be sent of the RNC; the HS-DSCH data frame comprises an existing HS-DSCH type one data frame and an existing HS-DSCH type two data frame, wherein in the HS-DSCH type one data frame and the HS-DSCH type two data frame, CmCH-PI is a priority indication of a corresponding priority queue, and the User Buffer Size is used for carrying total data volume information to be sent of an RNC.
Further, after step 101, the method may further include: each NodeB judges whether a user receiving the data to be sent of the RNC is a single-flow user, and when the user is the single-flow user, the data volume to be sent of the single-flow user in the current cell cache is counted; here, each NodeB determines the attributes of a user, specifically, a single-stream user or a multi-stream user, through a configuration process before receiving data sent by the RNC.
Further, before step 102, the method may further include: each NodeB allocates resources to the corresponding priority queue according to the received total data volume information to be transmitted of the RNC, the buffer size of the NodeB, the air interface capacity and the like;
102, each NodeB determines whether a user receiving data to be sent by the RNC is a multiflow user of an assisting cell, and when the user is a multiflow user of the assisting cell, feeds back to the RNC a pre-counted amount of data to be sent of a uniflow user in a cache of the assisting cell, where, when the assisting cell includes an assisting serving HS-DSCH cell and an assisting serving HS-DSCH cell, the amount of data to be sent is a sum of the amounts of data to be sent of the uniflow user of the assisting serving HS-DSCH cell and the assisting serving HS-DSCH cell;
here, before receiving data sent by the RNC, each NodeB can determine the attribute of a user through a configuration process, that is, the user is a single-flow user, a multi-flow user of a serving cell, a multi-flow user of an assisting cell, or the like;
specifically, each NodeB feeds back the amount of data to be sent of the single-flow user in the assisting cell cache to the RNC through an HS-DSCH capacity allocation frame used for feeding back the resource allocation condition of itself to the RNC;
the HS-DSCH capacity allocation frame includes an HS-DSCH type one capacity allocation frame and an HS-DSCH type two capacity allocation frame as shown in fig. 2a and fig. 2b, respectively, and the data amount indication field in fig. 2a and fig. 2b is used to indicate whether the currently used HS-DSCH capacity allocation frame includes the information of the amount of data to be transmitted, where, if the data amount indication is 0, it indicates that the information of the amount of data to be transmitted is not included, and if the data amount indication is 1, it indicates that the information of the amount of data to be transmitted is included; and a Data Volume field in the HS-DSCH type one capability allocation frame and the HS-DSCH type two capability allocation frame feeds back the Data Volume to be sent of the uniflow user in the assisting cell cache to the RNC, wherein the unit of the Data Volume field is Mbit/s.
103, the RNC distributes data to be transmitted to each NodeB according to the amount of data to be transmitted of the single-flow user fed back by each NodeB and the resource allocation condition fed back by each NodeB;
here, the RNC may calculate the air interface rate of each NodeB as (Maximum MAC-d/c PDU Length x HS-DSCH Credits)/HS-DSCH Interval according to the Maximum MAC-d/c PDU Length (Maximum MAC-d/c PDU Length), HS-DSCH allocation (HS-DSCH Credits), and HS-DSCH Interval (HS-DSCH Interval) in the HS-DSCH capability allocation frame;
specifically, the RNC determines whether the respective air interface rates of the serving cell and the assisting cell fed back by each NodeB are greater than or equal to a preset air interface rate threshold; here, the serving cell includes a primary serving HS-DSCH cell and/or a secondary serving HS-DSCH cell; the assisting cell comprises an assisting service HS-DSCH cell and an assisting auxiliary service HS-DSCH cell;
when the air interface rate of the serving cell and the air interface rate of the assisting cell are both greater than or equal to the air interface rate threshold, the RNC further judges whether the data volume to be sent of the assisted single stream user is greater than a preset data volume to be sent threshold, and if so, the data to be sent is distributed to the NodeB to which the serving cell belongs; if not, shunting the data to be transmitted to the NodeB to which the cell with the larger air interface rate belongs;
when the air interface rate of the serving cell is greater than or equal to the air interface rate threshold and the air interface rate of the assisting cell is smaller than the air interface rate threshold, the RNC distributes the data to be transmitted to the NodeB to which the serving cell belongs;
when the air interface rate of the serving cell and the air interface rate of the assisting cell are both smaller than the air interface rate threshold, the RNC distributes the data to be transmitted to NodeBs to which the serving cell and the assisting cell belong respectively according to the air interface rate proportion of the serving cell and the assisting cell;
when the air interface rate of the serving cell is less than the air interface rate threshold and the air interface rate of the assisting cell is greater than or equal to the air interface rate threshold, the RNC further judges whether the amount of data to be sent of the single-stream user of the assisting cell is greater than a preset threshold of the amount of data to be sent, and if so, the RNC distributes the data to be sent to the nodebs to which the serving cell and the assisting cell belong respectively according to the proportion of the air interface rates of the serving cell and the assisting cell; if not, shunting the data to be transmitted to the NodeB to which the assisting cell belongs;
the preset air interface rate threshold is N times of the user subscription rate, N is more than 0 and less than or equal to 1, and N is also called a tolerance factor of the air interface rate; the preset data volume threshold to be sent can be a cell theoretical maximum rate and an empty port loopback time M, wherein M is generally called a redundancy factor, and M is more than or equal to 1. The air interface loopback time refers to a time difference between the time when the NodeB sends data to the UE from the air interface and the time when the NodeB receives hybrid automatic repeat request (HARQ) feedback.
Fig. 3 shows an implementation flow of an embodiment of an HSDPA multiflow optimization method according to the present invention, where the scenario of the embodiment is as follows: RNC home Core Network (CN) management; NodeB1 and NodeB2 are managed by a home RNC; CELL1 home NodeB1 management; CELL2 home NodeB2 management; CELL1 and CELL2 have a common coverage area; the UE resides in a common coverage area of CELL1 and CELL2 and is in a HSDPA double-current state, wherein CELL1 is a service CELL, and CELL2 is an assisting CELL; the subscription rate of the UE is 40 Mbit/s; the tolerance factor N of the RNC to the air interface rate is 0.8.
As shown in fig. 3, the embodiment comprises the following steps:
step 301, RNC receives user data of UE from CN and requests resource to each NodeB, specifically, may request resource to each NodeB through HS-DSCH capability request frame;
here, the content filled in the User Buffer Size in the HS-DSCH capability request frame is the total amount of User data information of the UE received by the RNC.
Step 302, each NodeB determines whether the UE is a single-flow user, if so, step 303 is executed, otherwise, step 304 is executed;
step 303, each NodeB counts the amount of data to be transmitted of the single-flow user in the current cell cache, and then step 304 is executed;
step 304, each NodeB allocates resources for the corresponding priority queue;
step 305, each NodeB determines whether the UE is a helper cell user, if not, step 306 is executed, and if so, step 307 is executed;

step 307, each NodeB feeds back the resource allocation situation to the RNC, and carries the amount of data to be transmitted of the single flow user in the assisting cell, and step 308 is executed;
here, each NodeB feeds back the amount of data to be sent of the single stream user in the assisting cell cache to the RNC through the HS-DSCH capacity allocation frame;
step 308, the RNC determines whether NodeB1 meets a preset air interface rate threshold; if yes, go to step 309, otherwise go to step 313;
