Embodiment 1

[0086] Figure 10 It is a flow chart of switching between data radio bearers according to Embodiment 1 of the present invention, as shown in Figure 10 As shown, based on the connection established between the terminal and cell 1, the established data radio bearer ID is 1, and the corresponding EPS bearer ID is 1. Data radio bearer 1 only exists in base station 1. The conversion process is as follows:

[0087] Steps S1002-S1004: Due to the increase in the load of base station 1, base station 1 adds cell 3 to the terminal according to the measurement report, and at the same time moves data radio bearer 1 to base station 2, and sends a SeNB addition request to base station 2, which can carry the current data radio bearer 1 configuration information such as data bearer ID, etc.

[0088] Step S1006: Base station 2 reserves resources for data radio bearer 1 according to the current actual situation, and responds to SeNB to add a request to base station 1. The response may include ...

Embodiment 2

[0097] In this embodiment, the terminal establishes a connection with cell 1, and the established data radio bearer ID is 1, and the corresponding EPS bearer ID is 1. The data radio bearer 1 only exists in base station 1, and the type is MeNB bearer. This embodiment is still as Figure 10 As shown in , in the first embodiment, S1008 base station 1 does not send an instruction to the UE, but the UE determines the conversion operation by itself in S1010, and similarly S1024, the base station 1 does not send an instruction to the UE, but determines the switching operation by the UE in S1026 Transform operation. details as follows:

[0098] Steps S1002-S1004: Due to the increase in the load of base station 1, base station 1 adds cell 3 to the terminal according to the measurement report, and at the same time moves data radio bearer 1 to base station 2, and sends a SeNB addition request to base station 2, which can carry the current data radio bearer 1 configuration information s...

Embodiment 3

[0108] Figure 11 It is a flow chart of switching between data radio bearers according to Embodiment 3 of the present invention, as shown in Figure 11 As shown, based on the connection established between the terminal and cell 1, the established data radio bearer ID is 1, and the corresponding EPS bearer ID is 2. Data radio bearer 1 only exists on base station 1. The conversion process is as follows:

[0109] Steps S1102-S1104: Due to the increase in the load of base station 1, base station 1 adds cell 3 to the terminal according to the measurement report, and at the same time moves part of data radio bearer 1 to base station 2, that is, data radio bearer 1 becomes a split bearer and sends it to base station 2 The SeNB adds the request, which may carry the configuration information of the current data radio bearer 1 including the data bearer identifier and the like.

[0110] Step S1106: The base station 2 reserves resources for the data radio bearer 1 according to the curren...

Abstract

The invention discloses a DRB conversion method and a device. The method comprises steps that, a data carrying modification request sent by a first base station is received by the UE, the data carrying modification request contains configuration information of a first DRB on a second base station acquired from the second base station, and the first DRB is established on a first base station; the first DRB on the first base station is deleted temporarily by the UE, and a mapping relation between the first DRB on the first base station and evoluted EPS carrying; the first DRB is established on the second base station by the UE according to the configuration information. Through the method, a problem of wireless carrying conversion of data in different types in the prior art is solved, and use flexibility of the DRB is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a data radio bearer (DataRadio Bearer, DRB for short) conversion method and device. Background technique [0002] figure 1 It is a schematic diagram according to the overall architecture of the LTE system in the related art, such as figure 1 As shown, the architecture of the LTE system includes: a mobility management entity (MobilityManagementEntity, referred to as MME), a serving gateway (ServingGateWay, referred to as SGW), a user equipment (UserEquipment, referred to as UE, also called a terminal) and a base station (eNodeB, referred to as eNB); wherein, the interface between UE and eNB is UU interface, the interface between eNB and MME is S1-MME (S1 is used for the control plane (for the control plane)) interface, and the interface between eNB and SGW is S1-U interface, the interface between two eNBs is the X2 interface. Here, UE may also be called a terminal. [0003] ...
