As shown in Figure 2, the embodiment of the invention provides a kind of data interactive method, based on the base station, may further comprise the steps:
S11, the disposal ability of UE is known in the base station;
S12, the data interaction cycle of UE is determined according to the disposal ability of UE in the base station;
S13, the base station sends to UE with the configuration information in described data interaction cycle, so that UE carries out data interaction according to described data interaction cycle and base station.
The data interactive method that the embodiment of the invention provides, in the data interaction of UE and base station, the base station is that UE dynamically assigns the data interaction cycle according to the disposal ability of UE, make UE use its optimal data interaction cycle according to the disposal ability of self, can take full advantage of the disposal ability of UE, the encoding and decoding and the scheduling transmission that reduce data wait processing delay, thereby improve the data interaction speed of system, and the performance of communication system is improved significantly.
Wherein, UE and base station are carried out data interaction and are referred to carry out between UE and the base station exchanges data, comprise that base station or UE Data transmission are to the other side, and base station or UE receive the process of the data that the other side returns, for example, base station or the UE data to direction one's own side is sent are made corresponding response and are sent the process of data to the other side.
Wherein, after the data interaction cycle of UE refers to that UE receives the uplink authorization of base station or retransmits indication, according to uplink authorization or re-transmission indication upstream data is sent to the time of eating dishes without rice or wine, after referring to that also UE receives the downlink data of base station transmission, the feedback message that data are received sends to the time of eating dishes without rice or wine.
Wherein, the disposal ability of UE has reflected the handling property of UE when data interaction is carried out in UE and base station, the UE of different disposal ability, the needed exchanges data cycle is different when carrying out exchanges data with the base station, therefore, the base station can be the suitable exchanges data cycle of UE configuration according to the disposal ability of UE.
In one embodiment of the invention, the disposal ability of UE can characterize with the disposal ability grade that base station and UE both sides approve, each UE correspondence definite constant disposal ability grade.Wherein, the disposal ability grade of UE is the every performance index of producer, model or UE according to UE, memory size for example, and CPU frequency etc., predetermined.Illustrate, suppose the disposal ability of UE the strongest be made as grade one, inferior is grade two by force, by that analogy.Unit type is that the UE of KS-52 is that unit type is the upgrading products of the UE of KS-51, the former disposal ability the relative latter improve a lot, model is that the disposal ability grade of the UE of KS-52 is grade one, and model is that the disposal ability grade of the UE of KS-51 is grade two.
At this moment, in step S11, the disposal ability grade of UE will be known in the base station, and then in the S12 step, according to the disposal ability grade of UE, determine the data interaction cycle of UE.
Concrete, in step S11, the base station receives the disposal ability grade indication information that UE sends, thereby knows the disposal ability grade of UE.
Optionally, in the described disposal ability grade indication information, comprise the disposal ability class information of UE, which grade is the disposal ability grade that namely directly indicates UE be, that is the disposal ability grade of this UE can be known in the base station directly from described disposal ability grade indication information.
Optionally, in the described disposal ability grade indication information, comprise the information that has corresponding relation with the disposal ability grade of described UE, the performance index of at least a identification process ability of the product type of identify label ID, the UE of UE or UE for example, memory size for example, CPU frequency etc., optional, the identify label ID of UE can indicate the producer of UE.After the disposal ability grade that the base station receives described and described UE had the information of corresponding relation, again according to described information, and the corresponding relation of the disposal ability grade of described information and described UE was determined the disposal ability grade of UE.
Certainly, the base station also can be known the disposal ability grade of UE by alternate manner, and the present invention does not limit this.
Before the disposal ability grade indication information that receives UE, optional, the base station can also issue disposal ability grade query statement to UE, so that UE according to disposal ability grade query statement, reports disposal ability grade indication information.Wherein, the disposal ability query statement both can send to UE with an independent instruction type, also can increase query term in existing capability query instruction, was used for the disposal ability grade of inquiry UE, and the present invention does not limit this.
Optionally, in another embodiment of the present invention, the disposal ability of UE can be dynamic change, and at this moment, the disposal ability of UE can characterize with the identification parameter of sign UE disposal ability.Concrete, the identification parameter of sign UE disposal ability can be the cpu busy percentage of UE, the load condition of residential quarter, the UE physical location in the residential quarter, at least a in the current type of service of UE.
At this moment, in step S11, the identification parameter of sign UE disposal ability will be known in the base station, and then in the S12 step, according to described identification parameter, determine the data interaction cycle of UE.
Obviously, utilance affects the data interaction of UE and base station to the central processor CPU of UE (Central Processing Unit), if the cpu busy percentage of UE is higher, illustrates that UE disposal ability at this moment is relatively poor.Concrete, in step S11, the base station can be by knowing the cpu busy percentage of UE to the detection of the cpu busy percentage of UE.
The signal to noise ratio height of center of housing estate position data interactive signal, data interaction speed is fast, the cell edge position signalling a little less than, the signal interactive speed is slow.That is to say that the physical location of UE in the residential quarter also affects the disposal ability of UE.Optionally, in the embodiment of the invention, the physical location of UE in the residential quarter comprises: center of housing estate, cell edge is between center of housing estate and the cell edge.In step S 11, the base station can be by knowing the physical location of UE in the residential quarter to the detection of the physical location of UE in the residential quarter, concrete, the base station is by detecting Signal to Interference plus Noise Ratio SINR (the Signal to Interference plus Noise Ratio) test of UE correspondence, determine the physical location of UE in the residential quarter, for example, determine that UE is positioned at cell edge.
The load condition of residential quarter also affects the data interaction of UE and base station.If the UE quantity of cell load is more, the data traffic of single UE will be restricted, and the processing time that each UE is on average assigned in the base station will reduce relatively.Therefore, in order to guarantee the communication quality of base station and UE, the base station can be according to the load condition of residential quarter, UE place, and data interaction cycle of UE is optimized configuration, is the suitable data interaction cycle of UE configuration.Concrete, in step S11, the base station can be by knowing the load condition of residential quarter to the detection of the load condition of residential quarter.
For the different type of service of UE, the base station requires different with the real-time of the data interaction of UE.Therefore, the type of service difference of UE, the requirement difference in data interaction cycle, the different data interaction cycle of UE configuration can be come to be according to the difference of type of service in the base station.Concrete, in step S11, the base station can be by knowing the type of service of UE to the detection of the type of service of UE.
In another embodiment of the present invention, the disposal ability of UE can be in conjunction with the disposal ability grade of UE and the common sign of identification parameter institute of above-mentioned sign UE disposal ability, at this moment, the base station is except needs are known the disposal ability grade of UE, also need to know the identification parameter of sign UE disposal ability, it is the data interactive method of the embodiment of the invention, also comprise: the cpu busy percentage of described UE is known in described base station, the load condition of described UE residential quarter of living in, the physical location of described UE in its residential quarter of living in, each in the current type of service of described UE.In step S12, the data interaction cycle of UE will be determined according to disposal ability grade and the described identification parameter of the UE of knowing in the base station.
After knowing the disposal ability of UE, in step S12, the data interaction cycle of UE will be determined according to the disposal ability of the UE of knowing in the base station.In the base station, set in advance disposal ability and the corresponding relation in data interaction cycle of UE, the base station will be according to the disposal ability of knowing, for UE selects its disposal ability corresponding data interaction cycle.
Illustrate, set in advance the disposal ability grade of UE and the corresponding list item in data interaction cycle in the base station, know the disposal ability grade of UE when the base station after, the base station can be determined the data interaction cycle of described UE by query processing ability rating and the corresponding list item in data interaction cycle.For example, if the disposal ability grade of UE is grade one, represent that then the disposal ability of UE is the strongest, the data interaction cycle that this UE supports is 1ms, if the disposal ability grade is grade four, the disposal ability of then representing UE a little less than, the data interaction cycle that this UE supports is 4ms.
Be understandable that, with the disposal ability grade corresponding data interaction cycle of UE be the mutual cycle of minimum data that UE supports, be 1ms when the data interaction cycle that UE supports, UE can support all data interaction cycles more than or equal to the data interaction of 1ms.
When the disposal ability of UE is characterized by the identification parameter of above-mentioned sign UE disposal ability:
If the cpu busy percentage of UE is higher, illustrate that the disposal ability of UE this moment is relatively poor, the base station can be the bigger data interaction cycle of UE configuration, with the load of the CPU that reduces UE.
If the UE quantity of cell load is more, the data traffic of single UE will be restricted, and the processing time that every UE is on average assigned in the base station will reduce relatively.Therefore, in order to guarantee the communication quality of base station and UE, the base station can dispose the less data interaction cycle for UE.Like this, UE in the residential quarter carries out data interaction with single low discharge, high-frequency data interactive mode, the duration that is each data interaction suitably reduces, but increase the data interaction number of times in the unit interval, like this each UE can both be in time and the base station carry out data interaction, improved the exchanges data performance of system.
If UE is in cell edge, in order to improve the communication efficiency of this UE, the base station can dispose one than the mutual cycle of short data for this UE, for example be 2ms, like this, the Cell Edge User communication speed is improved, and switches the subscriber signaling interaction time delay and is able to effective reduction, thereby improved the performance of system.
For the different type of service of UE, the base station requires different with the real-time of the data interaction of UE.Therefore, the different data interaction cycle of UE configuration can be come to be according to the difference of type of service in the base station.Dispose the data interaction cycle of 1ms as the telephone service of having relatively high expectations for real-time, and be the data interaction cycle of the less demanding business of networking configuration of real-time 5ms.
When the disposal ability of UE is characterized with the identification parameter institute that indicates the UE disposal ability jointly by the disposal ability grade, in one embodiment of the invention, in step S12, the base station is at first according to the disposal ability grade of described UE, determine the data interaction cycle of described UE, it is the mutual cycle of minimum data that UE supports, then, the base station is according to the cpu busy percentage of described UE, the load condition of described UE residential quarter of living in, the physical location of described UE in its residential quarter of living in, each in the current type of service of described UE adjusted the data interaction cycle of described UE; At this moment, in S 13 steps, the configuration information in the data interaction cycle of the described UE after the base station will be adjusted sends to described UE.For example, the disposal ability grade of UE is grade two, the mutual cycle of minimum data that can support is 2ms, and the cpu busy percentage of this UE is higher, and greater than 90%, the base station will be according to the cpu busy percentage of this UE, the minimum data exchange cycle is adjusted, for this UE bigger data interaction cycle of configuration, as 4ms, to alleviate the load of its CPU.
In step S13, optionally, the base station can send to UE with the configuration information in data interaction cycle by layer three (L3) signaling, it is the data interaction cycle of UE configuration that the configuration information in data interaction cycle has been indicated base station among the step S12, so that UE carries out data interaction according to this data interaction cycle and base station.Optionally, the base station can also will be notified to UE for the data interaction cycle of UE configuration by the mode of update system message.The advice method of this update system message preferably is applicable to the situation that the UE of cell load is more.
Further, for the base station, the base station receives data that UE sends and will receive data and make feedback, after receiving the data that UE sends from the base station, the base station will be waited for behind the certain hour data are received and be made feedback, the length during this period of time of base station waits can be identical with the data interaction cycle of UE, also can be different, and the present invention does not limit this.Preferably, after the base station receives the data that UE uploads for data interaction cycle of its configuration according to the base station, the feedback that described data receive can be carried out according to the exchanges data cycle of described UE equally in described base station, further improve data interaction speed, reduce the processing delay of communication system, improved the performance of system.For example, the base station is that the data interaction cycle of UE configuration is 3ms, and after the data that receive the UE transmission, the base station will be after 3ms, reception is fed back to this secondary data, for example, if receive the data success, then the base station receives the data success message in the internal feedback of described data interaction cycle, if reception data failure, need UE this data that retransfer, then base station feedback is mixed automatic retransmission protocol HARQ (Hybrid Automatic Repeat request) information, requires UE this data that retransfer.
Concrete, with UE once up Ping bag business be example, when receiving outgoing data, UE begins, UE is eating dishes without rice or wine to send signal with the application uplink authorization at once, the base station is after the disposal ability of having understood UE, send data interaction cycle configuration information and uplink authorization to UE, UE will according to uplink authorization and to use the base station be that data interaction is carried out in data interaction cycle and the base station of its configuration, thereby reach the purpose of coming the exchanges data speed of control lag time, raising UE by the configuration in data interaction cycle, so data interaction efficient and the performance of system are greatly improved.
