Abstract
The invention provides a method and a device for long term evolution (LTE) change-over judgment based on timing advance (TA). TA value reported by a user equipment (UE) terminal is compared with protocol standard value, and increment operation is conducted on different obtained states so as to obtain mobile trend of the UE terminal through calculation and conduct calculation of total TA report times. The total TA times reported by the UE terminal are compared with preset threshold times and judged, whether reliability of the TA value reported by UE is compensated is determined according to a judgment result so as to enhance calculation accuracy of mobile trend of the UE terminal. When eNB conducts change-over processing on corresponding UE, change-over judgment processing is conducted according to the mobile trend of the UE, the mobile trend of the UE is obtained through calculation, accuracy of change-over judgment is enhanced, and change-over processing performance of the eNB is improved.
Description
Technical field
The present invention relates to communication technical field, be specifically related to a kind of LTE access network carries out switch decision based on UE terminal to report TA value method and device.
Background technology
LTE (Long Term Evolution, Long Term Evolution) project is the evolution of 3G, starts from the Toronto meeting of 3GPP in 2004.LTE is not the 4G technology that people generally misread, but a transition between 3G and the 4G technology is the global standards of 3.9G, and it improves and strengthened the aerial access technology of 3G, adopts OFDM and the MIMO sole criterion as its wireless network evolution.The peak rate of descending 326Mbit/s and up 86Mbit/s can be provided under the 20MHz spectral bandwidth.Improved the performance of Cell Edge User, improved cell capacity and reduce system delay.In the LTE network, user terminal is called the UE terminal, comprises mobile phone, intelligent terminal, multimedia equipment, stream media equipment or the like.In the standard of 3GPP LTE and LTE-A, represent the base station with eNB, corresponding with user UE.
In LTE Radio Access Network communication system, in the LTE Radio Access Network, implemented handoff technique in order to guarantee the customer service communication continuity.
Switch and normally to carry out in order to ensure the user; Promptly make and under the successional prerequisite of assurance customer service, accurately to switch; Need prevent also that simultaneously the user from frequently switching between cell-of-origin and Target cell, therefore the part of most critical is to adopt good switch decision technology in the handoff technique of implementing.
The switch decision technology that adopts in the LTE Radio Access Network communication system at present mainly is based on the UE terminal to the signal strength signal intensity of cell-of-origin and Target cell and the measurement of signal quality; And judge whether to carry out according to the target gate that is provided with and switch, it comprises following key step:
A, configuration UE terminal are to the signal strength signal intensity of cell-of-origin and Target cell and mass measurement thresholding, incident;
B, carry out corresponding switch decision according to the reported result of measurement of correlation incident and the target gate of setting;
There is the shortcoming of not considering UE and cell-of-origin relative position of living in and UE terminal mobile trend in the switch determining method based on signal strength signal intensity and quality that said system is implemented at present, because the complexity of wireless communication propagation environment can cause following problem:
For example; Can exist under the situation of distance sources sub-district, UE terminal close together, owing to the reason of radio transmission causes the signal strength signal intensity of cell-of-origin and the thresholding that quality is lower than setting, and the signal strength signal intensity of Target cell and quality are higher than the thresholding of setting; Thereby judgement is switched; After but UE left at the terminal environment at that time, the RST that measures will become normally, thereby caused switching again to carry out; Or; When not being since communication environments cause and the signal strength signal intensity of cell-of-origin and the thresholding that quality is lower than setting appear really; And the signal strength signal intensity of Target cell and quality are higher than the situation of the thresholding of setting, and judgement is at this moment switched, owing to do not consider the mobile trend at UE terminal; If when not changing, will cause the inaccurate or frequent switching of judgement near the direction of cell-of-origin or relative position at the UE mobile trend.
Summary of the invention
Main purpose of the present invention provides a kind of LTE switch determining method and network equipment based on TA, with the accuracy of guaranteeing switch decision in the LTE access network with avoid frequent switching, thereby improve the performance of hand-off process in the LTE access network.
Technical scheme of the present invention is a kind of LTE switch determining method based on TA, and the up Timing Advance in UE terminal that measures according to the eNB side carries out switch decision, and up Timing Advance is designated as the TA value, carry out switch decision and may further comprise the steps,
Step 1; Carry out UE terminal mobile trend statistics; Comprise the initial sum duration of setting UE terminal mobile trend timing statistics section; TA value according to the UE terminal to report in the timing statistics section is added up, and draws the mobile trend information at UE terminal, and statistics UE terminal reports the total degree of TA value in the timing statistics section;
Step 2; The total degree of comparison step 1 gained UE terminal to report TA value and preset number of times thresholding if total degree is less than preset number of times thresholding, compensate the confidence level of the TA value of UE terminal to report; Comprise that continuation adds up according to the TA value of UE terminal to report; The mobile trend information at adjustment UE terminal reaches preset number of times thresholding up to the total degree of UE terminal to report TA value and gets into step 3 then, otherwise directly gets into step 3;
Step 3 is analyzed according to the mobile trend information at UE terminal by eNB, switch decision is carried out at the UE terminal handle.
And the mobile trend information at said UE terminal comprises UE terminal mobile trend statistical variable K1, K2, K3, and step 1 comprises following substep,

Step 1.3 in the timing statistics section, is compared the TA value that the UE terminal reports at every turn with protocol definition TA variation fiducial value 31, carry out accrual accounting according to result relatively, adds up the UE terminal reports TA in the timing statistics section total degree simultaneously; The concrete mode of accrual accounting is following,
If the result of the double comparison in front and back is greater than 31, UE terminal mobile trend statistical variable K1 is carried out increment handle, step value is 1;
If the result of the double comparison in front and back is less than 31, UE terminal mobile trend statistical variable K2 is carried out increment handle, step value is 1;
If the result of the double comparison in front and back be once greater than 31, once less than 31, UE terminal mobile trend statistical variable K3 is carried out increment handles, step value is 1.
And, in the step 3, analyze according to step 1.3 gained UE terminal mobile trend statistical variable K1, K2, K3, switch decision to be carried out at the UE terminal handle, concrete mode is following,
As K1+K2>(K1+K2+K3)/2 and K1=during K2, be judged as the UE terminal and move to direction away from eNB, directly carry out hand-off process;
As K1+K2>(K1+K2+K3)/2 and K1<during K2, be judged as the UE terminal and move to direction near eNB, withdraw from this switch decision and handle;
During other situation, the distance that is judged as between UE terminal and the eNB does not change, and gets into other switch decision processing modes.
The present invention also provides a kind of LTE switch decision device based on TA, it is characterized in that: comprise that the UE mobile trend statistic unit, the TA that connect successively report confidence level compensating unit and switch decision unit,
