Description
Technical field
The present invention relates to the communications field, relate in particular to the method and apparatus of the transmission rate of the packet of control forward link in a kind of wireless communication field.
Background technology
At CDMA (Code Division Multiple Acess, code division multiple access) 2000 1x-EVDOrevA (1x-RTT EVolution to packet Data Optimized technique, grouped data optimisation technique from single band evolution) the technology, the base station sends each information code with total power, and terminal decides the transmission rate of forward link according to own residing wireless environment.In nearer zone, distance base station, terminal is generally selected a bigger transmission rate; In zone far away, distance base station, terminal is generally selected a less transmission rate.Terminal ceaselessly reports to the base station to the speed indication information of selecting by backward channel, and packet is assembled according to the speed of above-mentioned speed indication information indication in the base station, and on the forward link this packet is sent to terminal.Above-mentioned speed indication information is called DRC (Data Rata Control, data rate control) information, this DRC information has determined the packet format of the packet that the base station sends to terminal on the forward link, and promptly the packet format of every kind of packet is corresponding with a kind of speed of DRC information indication.
Terminal is determined above-mentioned DRC information by corresponding rate selection algorithm, therefore, under certain wireless environment, the rate selection algorithm of terminal has determined the link-quality of forward link, this link-quality can use PER (Packet Error Ratio, Packet Error Ratio) to weigh.
In CDMA2000 EVDO agreement, after terminal is received the forward data bag that the base station sends, if correct this packet of demodulation, and verification would pass through, and then sends ACK (Acknowledgement correctly replys) to the base station in reverse link and indicates; If can not be correctly decoded this packet, then in reverse link, send NAK (Negative Acknowledgement, wrong responses) indication to the base station.The base station can be according to the PER of these indication statistics forward links.
Because the rate selection algorithm of the terminal that different manufacturers is produced may be different.And a kind of rate selection algorithm often can not be fit to all wireless channel scenes.So the link-quality of the forward link of terminal can not get better controlled sometimes.Because EVDO agreement regulation RLP (Radio Link Protocol, radio link protocol) layer for once retransmits, when the error rate of eating dishes without rice or wine was higher, the very difficult re-transmission by the RLP layer dropped to upper-layer protocol (as the TCP layer) required standard to Packet Error Ratio.Test shows, the Packet Error Ratio of eating dishes without rice or wine of terminal is approaching or surpass at 1% o'clock, and its forward direction speed will be seriously influenced.
In actual applications, the base station need be by the transmission rate of certain means control forward link, thereby the Packet Error Ratio of control forward link is at certain below the thresholding, to satisfy the transmission requirement of upper-layer protocol.
EVDO revA agreement has been stipulated 15 kinds of DRC values, and the corresponding respectively DRC index of each DRC value is 0,1,2 ..., A, B, C, D, E.
The DRCOffset attribute (speed biasing attribute) of terminal is provided in CDMA2000 EVDO revA agreement, and this speed biasing attribute is used for above-mentioned DRC information index (N) is adjusted.This DRCOffset property value can be revised by attribute updating message (AttributeUpdateRequest) indicating terminal in the base station.
The computational process of the transmission rate of above-mentioned forward link is as follows:
Terminal is determined the DRC information that an index is N according to wireless environment and the rate selection algorithm of oneself, then, DRCOffset property value (DRCOffsetN) according to correspondence is adjusted this N value, and then adjusted DRC information index is: M=N-DRCOffsetN.
Afterwards, terminal sends to the base station by reverse link with above-mentioned adjusted DRC information index value, and the transmission rate of forward link is determined in the base station according to the indicated speed of this adjusted DRC information index value.So,, just can adjust the transmission rate of the forward link of base station by adjusting the DRCOffset property value of terminal.Thereby the link-quality of the forward link of control base station, i.e. Packet Error Ratio.
A kind of method of controlling the link-quality of forward link is in the prior art: the user is provided with fixing less DRC information in the dialing modem of wireless terminal (modulator-demodulator) attribute when using EVDO professional.Thereby reduce the transmission rate of the forward link of base station, and then obtain the link-quality of forward link preferably.
In realizing process of the present invention, the inventor finds that the shortcoming of the method for above-mentioned prior art is:
1, be provided with in the dialing modem of wireless terminal fixedly that DRC information is a debug function, non-consensus standard definition, the part terminal is not supported.And the general user does not understand notions such as DRC information.
2, fixedly DRC information can not be adjusted according to wireless environment adaptively.Under the situation of wireless environment difference, the link-quality that can't obtain; Under the good situation of wireless environment, grievous injury throughput.
3, end side fixing DRC information voluntarily can not cooperate with base station side.Reduced sector throughput (being power system capacity).
