Description
Technical field
The present invention relates to wireless communication technology field, be specifically related to diversity reception method for handover control and diversity receiver.
Background technology
Fading effect is one of principal element affecting radio communication quality.In order to the impact of receiving anti-fading docking, two secondary or how secondary reception antennas can be utilized, the very little signal being loaded with same message of mutual correlation is received respectively on each branch road, then again each tributary signal is merged by folding and export, thus the impact of decline on system is greatly reduced on receiving terminal, improve receiving sensitivity.
Space diversity reception is while raising receptivity, need the receiver using more than 2 tunnels in receiver, therefore compared with single antenna, the power consumption of radio circuit and digital receive circuit can increase, and the stand-by time of mobile terminal or air time can corresponding minimizings.Current, battery technology is still one of bottleneck of Mobile Communication Development, and therefore in the mobile terminal using diversity receiving technology, keeping, the prerequisite decline low-power consumption of communication quality is extremely important.
In current diversity receiver technical scheme, there is multiple method can realize terminal and switch between diversity reception and single antenna reception, to reach the object reducing power consumption.Such as:
Method one, first, detect the quality of reception on each road of multiple receiving branch, this quality of reception can be in the respective incoming level of multiple receiving branch, automatic growth control (AGC, Automatic Gain Control) level, the error rate, packet error rate and carrier-to-noise ratio any one or more; Then the difference of the quality of reception between multiple receiving branch is calculated, according to the difference value of the quality of reception between each receiving branch, change and use the diversity reception work of multiple receiving branch and the ratio of single branch road reception work, control startup and the stopping of diversity operation, to reach the object reducing power consumption.
Method two, receiving system switching part switch threshold values based on receiving system and switch between single reception and diversity reception.Receiving system upgrades receiving system according to the acceptance rate calculated and switches threshold values.If the quality of reception calculated is more than or equal to receive switch threshold values, then switching off diversity receives, and a use single antenna receives; If the quality of reception is less than receiving system switch threshold values, then open diversity reception.Wherein, by calculating the power ratio of signal and noise, namely C/N [dB] is as the quality of reception.
Method three, the measurement diversity reception gain when diversity reception, when after diversity reception gain reduction certain value, if receiving quality is now more than the value preset, then stops the reception work of the receiving branch that presets or the low branch road of receiving quality, and then reach the object of power saving.Receiving quality uses the error rate or Packet Error Ratio etc. to weigh.
Method four, calculate the error rate according to demodulation result, based on this error rate, calculate the switching frequency of startup that alternately switched diversity receives and stopping.According to switching frequency, select the switching of two receiving branch both sides or the switching of any one in both, reach power saving object.
Method five, the level value of the base station transmit signals received and threshold values to be compared, when the former receives, when the former opens diversity reception lower than during the latter higher than switching off diversity during the latter; When the level value of the signal that travelling carriage sends to base station is lower than threshold values, stop diversity reception; When receiver utilizes common signal channel to communicate, and travelling carriage temporarily stops diversity reception to the level value of base station transmit signals lower than during threshold values; When the translational speed of receiver receives lower than switching off diversity during setting.
The shortcoming of the diversity reception control method that prior art proposes is as follows:
One, the business do not considered SOT state of termination and carry out.
Terminal can be in standby or service connected state in a network.According to the difference of business, speech business, data service and other business can be divided into.Current, most mobile terminal not only support voice business but also supported data business.When making user obtain good Consumer's Experience, different business is different to the requirement of channel circumstance, signal quality.Because the speed of speech business is generally fixed value, and all plan according to single antenna terminal during the network planning, even if therefore use single antenna, in most situation, also can ensure that speech business is working properly.And for data service, especially high-speed slender body theory (HSDPA, High Speed Downlink Packet Access) etc. high-speed data service, its accessible data rate is directly relevant to the signal strength signal intensity that channel circumstance, receiver receive, use the receiver of double antenna can significantly improve the signal strength signal intensity of terminal reception, thus raising downloading rate, and then improve Consumer's Experience.Therefore for speech business and data service, different indexs need be used, and should not use the switch of identical norm controlling diversity reception, thus reach and both ensured quality of service, the power consumption of terminal can be reduced again.
Two, for different business, identical method is used to control opening and closedown of diversity reception.
End is under different scenes, different classs of business, and diversity reception role is different.In order to ensure quality of service, reduce terminal power consumption, when the business such as standby, voice, data, terminal can switch respectively under what conditions between diversity reception and single antenna reception simultaneously, and prior art fails to propose.
