Problems solved by technology

At this time, if the above-mentioned mobility state estimation method is applied, and only the number of handovers is used as the basis for judging the UE’s moving speed, the UE’s moving speed will be seriously overestimated, and the TTT will be adjusted too low, resulting in serious ping-pong effect

Embodiment 1

[0054] figure 1 A flowchart of a method for adjusting TTT according to an embodiment of the present invention is shown. like figure 1 As shown, the method mainly includes:

[0055] Step 101, when a mobile terminal (UE) is handed over, the target base station (TeNB) acquires handover assistance information of the UE;

[0056] Step 102, the TeNB determines the handover weight of this handover according to the handover assistance information of the UE;

[0057] Step 103, the TeNB sends a handover command to the UE, and carries the above handover weight in the handover command;

[0058] Step 104, the UE performs handover counting according to the handover weight in the handover command, and obtains the updated number of handovers; and

[0059] Step 105, the UE adjusts the TTT according to the updated handover times.

[0060] Will further describe in detail below in conjunction with accompanying drawing figure 1 The specific implementation method of each step in.

[0061] As...

Embodiment 2

[0093] image 3 A method for adjusting TTT according to another embodiment of the present invention is shown. like image 3 As shown, the method mainly includes:

[0094] In step 301, the UE determines the weight of this handover according to its own handover assistance information.

[0095] In step 302, the UE performs handover counting according to the handover weight to obtain the updated number of handovers. Wherein, the execution method of step 302 is the same as that of step 104 in the above-mentioned embodiment 1, and will not be repeated here.

[0096] In step 303, the UE adjusts the TTT according to the updated handover times. Wherein, the execution method of step 303 is also the same as that of step 105 in the above-mentioned embodiment 1, and will not be repeated here.

[0097] Will further describe in detail below in conjunction with accompanying drawing Figure 4 The execution method of step 301.

[0098] As mentioned above, the handover assistance informat...

Embodiment 3

[0113] Figure 5 The method for adjusting TTT according to another embodiment of the present invention is shown. like Figure 5 As shown, the method mainly includes:

[0114] Step 501: Preset the initial value TTT of TTT 0 .

[0115] As mentioned earlier, the system is setting the initial value of TTT TTT 0 The average station spacing or network density can be further considered. For example, when the average station spacing is small or the network density is high, set a lower initial value of TTT TTT 0 , and set a higher initial value of TTT TTT when the average station spacing is large or the network density is low 0 .

[0116] Step 502: Preset n thresholds thre 1 ,thre 2 ,...,thre n And the n coefficients factor corresponding to these n thresholds 1 , factor 2 ,...,factor n , satisfy 0factor 1 >factor 2 >…>factor n >0; where n is a natural number.

[0117] Step 503: UE performs handover counting, and every time a handover occurs, the handover counter value ...

Abstract

The invention discloses a method for adjusting time to trigger (TTT). The method comprises the steps that when a mobile terminal (UE) switches, a target base station (TeNB) obtains the auxiliary switching information of the UE and determines the weight of switching this time according to the auxiliary switching information of the UE; the TeNB issues a switching command to the UE, wherein the switching weight is carried in the switching command; the UE performs switching counting according to the switching weight in the switching command to obtain updated switching frequency; the UE adjusts the TTT according to the updated switching frequency. The invention further discloses the base station and the UE for adjusting the TTT.

Description

technical field [0001] The present application relates to mobile communication technologies, and in particular to a method and device for adjusting the trigger time of reporting a measurement report by a mobile communication device during a handover process. Background technique [0002] Cellular mobile phones have brought great convenience to people's communication. As an important organization in the mobile communication field, the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) has greatly promoted the standardization progress of the third generation mobile communication technology (The Third Generation, 3G). A few days ago, in order to meet the challenges of broadband access technology and meet the growing demands of new services, 3GPP started the standardization of 3G Long Term Evolution (LTE) technology at the end of 2004, hoping to further improve spectrum efficiency and improve cell The performance of edge users, reducing system delay, ...
