Embodiment 1

[0029] Embodiment 1 of the present invention provides a data bearer migration method, such as figure 1 As shown, the secondary carrier deconfiguration method includes the following steps:

[0030] Step 101, obtain the remaining resources M in the MeNB and the remaining resources S in the SeNB, and obtain the sum N of currently occupied PRB resources according to all bearers established by the UE;

[0031] Step 102, determine the bearer to be migrated according to M, S, N;

[0032] Step 103, migrate the bearer to be migrated from the MeNB to the SeNB.

[0033] Wherein, the determination of the bearer to be migrated according to M, S, and N in the process of step 102 includes: for the case where N is greater than or equal to S, determining the bearer with the smallest PRB resource occupied by the current UE on the MeNB as the bearer to be migrated; For the case where N is less than S, and S-N is greater than M, all the bearers of the current UE on the MeNB are determined as be...

example 1

[0042] Currently, the downlink bandwidth of MeNB and SeNB is 100RB. UE has established three bearers on MeNB, which are QCI9, QCI7, and QCI4 respectively. The MCS (Modulation and Coding Scheme) of UE is 12. The three bearers The rates are 8kps, 64kps, and 256*8kps respectively.

[0043] S101: The MeNB determines the sum of PRB resources currently occupied by the UE according to the three bearers established by the UE N=13RB; the remaining PRB resources in the MeNB are M=70RB; the MeNB acquires the remaining PRB resources in the SeNB S=100RB;

[0044] S102: According to the fact that N is smaller than S and (S-N) is larger than M, the MeNB determines that all bearers of the current UE on the MeNB are bearers to be migrated.

[0045] S103: The MeNB migrates all bearers of the current UE on the MeNB from the MeNB to the SeNB.

example 2

[0047] The cell downlink bandwidth of MeNB and SeNB is currently 100RB. UE has currently established 3 bearers on MeNB, namely QCI9, QCI4, and QCI3. The MCS of UE is 16. The rates of the three bearers are 8kps, 256*8kps, and 256* respectively. 8kps.

[0048] S201: The MeNB determines the sum of PRB resources currently occupied by the UE according to all bearers established by the UE, N=15RB; the remaining PRB resources in the MeNB are M=70RB; the remaining PRB resources in the SeNB are S=80RB;

[0049] S202: According to the fact that N is less than S, and (S-N) is less than M, and the current UE has currently established three bearers of QCI9, QCI4, and QCI3, their rates are 8kps, 256*8kps, and 256*8kps respectively, and because the current MCS of the UE = 16, according to the relevant agreement, it can be determined that the PRB resources that three bearers need to occupy are: bearer QCI9 needs to occupy 1 RB, bearer QCI4 needs to occupy 7 RB, bearer QCI3 needs to occupy 7 R...

Abstract

The invention discloses a data bearer migration method which comprises the steps of acquiring a residual resource M in an MeNB and a residual resource S in an SeNB, and a sum N of resources which are currently occupied by all bearers which are established by user equipment (UE); determining a to-be-migrated bearer according to the M, S and N; and migrating the to-be-migrated bearer from the MeNB to the SeNB. The invention further discloses a data bearer migration device which comprises the components of an information acquiring module which is used for acquiring the residual resource M in the MeNB and the residual resource S in the SeNB, and the sum N of the resources which are currently occupied by all the bearers that are established by the user equipment (UE); a to-be-migrated bearer determining module which is used for determining the to-be-migrated bearer according to the M, S and N; and a bearer migration module which migrates the to-be-migrated bearer from the MeNB to the SeNB.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a data bearing migration method, device and system. Background technique [0002] The International Telecommunications Union (ITU) puts forward very strict requirements on the performance of the next generation mobile communication system, such as the maximum system transmission bandwidth of 100MHz, and the peak rate of uplink and downlink data transmission needs to reach 1G bps and 500M bps respectively; And put forward a very high demand on the average spectral efficiency of the system, especially the edge spectral efficiency. In order to be better compatible with the existing Long Term Evolution (LTE) standards, reduce the complexity of standardization work, and support flexible application scenarios, the 3rd Generation Partnership Project (3GPP) introduced Dual Connectivity (DC for short) technology. [0003] The dual connectivity technology means that ...
