AI Technical Summary

Problems solved by technology

However, due to the low transmission power of low-power nodes, their cell coverage is much smaller than that of traditional macro cells, especially for low-power nodes deployed on the same frequency, that is, the operating frequency of macro cells and the work of low-power nodes deployed within their coverage. When the frequency is the same, if the handover is not timely, the user equipment (User Equipment, referred to as UE) will be strongly interfered by the macro cell or the low-power node cell at the edge of the macro cell and the low-power node cell, thus Cause handover failure or UE call drop, ultimately affecting user experience and system performance
[0006] Therefore, in a network where macro cells and low-power node cells coexist, how to correctly and efficiently realize reliable and seamless UE handover between macro cells and low-power node cells directly affects user experience and is related to the deployment of low-power nodes Whether it can truly enhance the coverage of traditional macro cells, enhance network capacity, and share the load of macro cells, which ultimately affects system performance
However, the existing handover processing method between the macro cell and the macro cell cannot guarantee the reliable and seamless handover of the UE between the macro cell and the low-power node cell.

Embodiment 1

[0099] The UE moves from the macro cell to the handover area between the macro cell and the LPN cell, or the UE moves from the LPN cell to the handover area between the LPN cell and the macro cell. There is a direct physical connection X2 interface between the source base station (S-eNB) where the macro cell is located and the LPN node (T-eNB) where the LPN cell is located.

[0100] Such as Figure 7 As shown, in order to enhance the handover performance of the UE when switching between the macro cell and the LPN cell, the specific implementation of this embodiment is described as follows:

[0101] Step 701. Measure;

[0102] The UE measures the signal quality of the serving cell and neighboring cells.

[0103] Step 702. UE reports measurement report to S-eNB;

[0104] According to the measurement in step 701, the UE reports a measurement report, and the signal quality of the target cell is reported in the measurement report.

[0105] Step 703. After receiving the measurem...

Embodiment 2

[0118] In this embodiment, the UE moves from the macro cell to the handover area between the macro cell and the LPN cell, or the UE moves from the LPN cell to the handover area between the LPN cell and the macro cell. There is no direct physical connection X2 interface between the source base station (S-eNB) where the macro cell is located and the LPN node (T-eNB) where the LPN cell is located. The handover signaling between eNBs must be forwarded by a network element of the core network, for example, forwarded by a mobility management entity (Mobility Management Entity, MME).

[0119] Such as Figure 9 As shown, in order to enhance the handover performance of the UE when switching between the macro cell and the LPN cell, the specific implementation of this embodiment is as follows:

[0120] Step 901. Measure;

[0121] The UE measures the signal quality of the serving cell and neighboring cells.

[0122] Step 902. UE reports measurement report to S-eNB;

[0123] The UE rep...

Embodiment 3

[0140] The UE moves from the macro cell to the handover area between the macro cell and the LPN cell, or the UE moves from the LPN cell to the handover area between the LPN cell and the macro cell. There is a direct physical connection X2 interface between the source base station (S-eNB) where the macro cell is located and the LPN node (T-eNB) where the LPN cell is located.

[0141] Such as Figure 10 As shown, in order to enhance the handover performance of the UE when switching between the macro cell and the LPN cell, the specific implementation of this embodiment is described as follows:

[0142] Step 1001. The UE sends an indication of approaching the LPN cell to the S-eNB;

[0143] The UE finds that it is approaching an LPN cell through the positioning information or the location information of the LPN cell it has accessed, and sends an indication of approaching the LPN cell to the S-eNB.

[0144] Step 1002. The S-eNB sends an interference avoidance request, or a handov...

Abstract

The invention discloses a switching processing method and a switching processing system. A target base station sends switching information to a source base station, the switching information comprises time division multiplexing distribution information which is configured for the target base station, and the source base station and / or the target base station are / is dispatched according to the switching information. By the invention, the switching performance of user equipment (UE) which is switched between a macro cell and a lower power node (LPN) cell can be improved, the probability of switching failure and the probability of call drop are reduced, and user experience and network performance are improved.
