Description
Technical Field
The invention relates to the field of communication, in particular to a communication flow control method and device.
Background
The cdma2000HRPD network is a high-speed packet data network based on cdma2000 technology, and can meet the increasing high-speed packet data requirements of users, including services such as multimedia and the like. In the enhancement process of the cdma2000HRPD air interface, the performance of single carrier multi-stream (onesinglecerrirmulti-streaming) is introduced.
The multi-streaming (multi-streaming) technology is mainly used to enhance the effect of the edge cell coverage terminal receiving the basic data service, and the expression form is usually: terminals in coverage areas of multiple cells receive data packets sent independently from multiple base stations or access networks (access networks).
The terminal at the cell edge receives data from multiple base stations independently, and basically, the terminal at the cell edge receives data from multiple base stations and feeds back the current channel condition to the base stations to assist the scheduler of the base stations in making scheduling decisions. In addition, the terminal is also capable of monitoring the corresponding downlink control channel and receiving data from each base station.
It should be noted that the terminals located at the cell edge may also create problems while benefiting from the simultaneous acquisition of transmission data from multiple base stations. Each base station is independently scheduled, and each base station independently transmits data to the terminal according to a fair and reasonable principle or algorithm; therefore, the terminal gains benefits while impairing the experience of other terminals of the base station, which impairs the fairness of other terminals located outside the cell edge.
In order to avoid the above problems, a flow control concept is proposed in the standard discussion: the target base station of the terminal periodically sends the current throughput information of the target base station to the source base station, the source base station gathers the throughputs of different target base stations from the terminal, and the gathered throughputs are sent to each target base station to serve as a reference for flow control. However, this method causes the following problems:
the throughput information sent by the target base station to the source base station is too frequent and the information amount is too large, so that the overhead between the target base station and the source base station is huge, and the normal and smooth communication of the terminal is easily influenced;
the aggregated throughput cannot actually reflect the current situation of the actual link, so that the flow control performed for the terminal is also inaccurate, and the situation that the stability of the throughput received by the terminal is poor as shown in fig. 1 occurs; inaccurate flow control can significantly affect the communication quality of the terminal and reduce user satisfaction. In fig. 1, the ordinate is the throughput received by the terminal, and the abscissa is the time taken for the terminal to receive the throughput.

Detailed Description
In general, the operation of implementing communication flow control mainly includes the following steps:
a, a source base station of a terminal knows the actual condition of a current link channel from a target base station, and can be called as link information;
b, each target base station feeds current link information back to the source base station;
c, the source base station calculates the throughput and other related information sent to the terminal by each target base station according to the received link information of the target base stations, and feeds the throughput and other related information back to each target base station; the calculated throughput may be referred to as a target throughput.
And D, each target base station controls the throughput applicable to the communication with the terminal through the scheduler according to the received throughput.
In the above step C, there may be various methods for the source base station to calculate the target throughput of each target base station, and the calculation process may depend on the scheduling algorithm of the scheduler of the source base station or other parameters in the actual application scenario.
Such as: assuming that the terminal currently has n links, Tt represents the total throughput provided by the terminal, T [ i ] represents the effective link throughput at cell [ i ], and Tc [ i ] represents the average link capacity of cell [ i ], which can be calculated from the average DRC (data rate control) value over a period of time. Thus, Ti/Tc i represents the scheduling efficiency at cell [ i ] or the load corresponding to cell [ i ]. Tt [ i ] is the throughput of the target link in cell [ i ], and is used to indicate the maximum limit of the throughput obtained in cell [ i ] according to the fairness algorithm of the target cell, and can be calculated as follows:
Tt[i]＝Tt*(T[i]/Tc[i])/(T[1]/Tc[1]+T[2]/Tc[2]+....+T[n]/Tc[n])。
based on the above operation idea, the flow shown in fig. 2 can be performed. Referring to fig. 2, fig. 2 is a flow chart of communication flow control according to an embodiment of the present invention, where the flow chart includes the following steps:
step 201: the source base station of the terminal transmits a link query message to the target base station 1 of the terminal to query link information of the terminal identified as an Access Terminal Identifier (ATID). The link query message may be a link query (QueryLink) message of an interface between two base stations.
Step 202: the source base station of the terminal sends a link query message to the target base station 2 of the terminal to query the link information of the terminal identified as ATID.
Step 201 and step 202 are not strictly sequential when actually executed.
Step 203: the target base station 1 sends a link information message to the source base station, where the message includes link throughput (LinkThroughput), link capacity (LinkCapacity), and the like. The link information message may be a link information (LinkInfo) message of an interface between two base stations.
Step 204: the target base station 2 sends a link information message to the source base station, which includes the link throughput and link capacity information.
Step 203 and step 204 are not strictly sequential when actually executed.
Step 205: and the source base station calculates the throughput distribution value of each target base station aiming at the terminal based on the link information such as the link throughput and the load information fed back by each target base station.
Thereafter, the source base station transmits a set link message to the target base station 1, the message including the throughput distribution value of the target base station 1 for the terminal. And the target base station 1 schedules the data transmission flow to the terminal according to the received throughput distribution value.
Step 206: the source base station transmits a set link message to the target base station 2, the message including a throughput distribution value of the target base station 2 for the terminal. And the target base station 2 schedules the data transmission flow to the terminal according to the received throughput distribution value.
Step 205 and step 206 are not strictly sequential when actually executed.
As can be seen from the above, the operation concept for realizing the communication flow control can be shown in fig. 3. Referring to fig. 3, fig. 3 is a simplified communication flow control process diagram according to the present invention, which includes the following steps:
step 310: the source base station of the terminal acquires the link information of the target base station.
Step 320: and the source base station determines the throughput suitable for the communication between each target base station and the terminal according to the acquired link information of the target base station.
In order to ensure that the above operation flow can be smoothly performed, the arrangement shown in fig. 4 may be performed. Referring to fig. 4, fig. 4 is a diagram of a communication flow control apparatus according to an embodiment of the present invention, where the apparatus includes a link information obtaining unit and a throughput decision unit, and the two units may be separately or jointly disposed in a device such as a base station.
In specific application, the link information obtaining unit can obtain the link information of the target base station in an active query mode, such as: link throughput and cell load information, etc. Moreover, the link information obtaining unit can also send the obtained link information of the target base station to the throughput decision unit, and the throughput decision unit determines the throughput applicable when each target base station communicates with the terminal according to the received link information of the target base station, such as: a throughput distribution value of the target base station for the terminal, and the like.
Then, the throughput decision unit can send the throughput determined for each target base station to the corresponding target base station, and each target base station schedules the data transmission flow to the terminal according to the received throughput.
In summary, the communication flow control technique of the present invention, regardless of the method or the apparatus, can avoid the situation that the throughput information sent by the target base station to the source base station is too frequent and the information amount is too large, and relatively independently determine the throughput suitable for the communication with the terminal for each target base station; therefore, the accuracy of flow control for the terminal can be effectively improved, and the user satisfaction is improved.
