Embodiment 1

[0064] Embodiment 1. A handover method in a heterogeneous network, such as image 3 shown, including:

[0065] S10. Detecting the traffic load of the macro cell, when the traffic load of the macro cell is greater than or equal to the first threshold

[0066] Start a measurement process, and receive measurement results reported by user terminals under the macro cell;

[0067] S20. Initiate handover of the user terminal under the macro cell to the micro cell when the measurement result indicates that there is a micro cell whose service priority is higher than that of the macro cell.

[0068] Wherein, S10 and S20 may be performed by an entity having a control function in the macro cell (system side), such as but not limited to a main control unit in the macro cell.

[0069] In this embodiment, the service priority includes but not limited to frequency point priority, cell priority, etc.; this embodiment can automatically trigger the user terminal in the macro cell with low serv...

Embodiment 2

[0097] Embodiment 2. A handover method in a heterogeneous network, such as Figure 4 shown, including:

[0098] S30. Detect the service load of the micro cell, and start a measurement process when the service load of the micro cell is less than or equal to a third threshold, and receive the measurement results reported by the user terminals under the micro cell;

[0099] S40. When the measurement result indicates that the service priority of the macro cell is higher than that of the micro cell, initiate handover of the user terminal under the micro cell to the macro cell.

[0100] Optionally, the method also includes:

[0101] When the duration of the user terminal without access to the micro cell exceeds or reaches the time threshold, report an idle resource status indication message to the controller on the network side; the idle resource status indication message is used to indicate the The controller deactivates the micro cell.

[0102] Optionally, before detecting the ...

Embodiment 3

[0106] Embodiment 3. A switching device in a heterogeneous network, such as Figure 5 shown, including:

[0107] The first trigger module 51 is configured to detect the traffic load of the macro cell, and when the traffic load of the macro cell is greater than or equal to a first threshold, start a measurement process and receive the measurement results reported by the user terminals under the macro cell;

[0108] The first handover control module 52 is configured to initiate handover of the user terminal under the macro cell to the micro cell when the measurement result indicates that there is a micro cell whose service priority is higher than that of the macro cell .

[0109] The first trigger module and the first handover control module may be but not limited to be set in the main control unit of the macro cell.

[0110] Optionally, the first triggering module 51 is further configured to set the macro cell to The service priority of the cell is adjusted to the second pri...

Abstract

The invention provides a handoff method and apparatus in a heterogeneous network. The method includes: detecting the business load of a macro-cell, starting a user terminal measuring process of the macro-cell when the business load of the macro-cell is greater than or equal to a first threshold, and receiving a measuring result reported by a user terminal of the macro-cell; and initiating the handoff to the micro-cell by the user terminal of the macro-cell when the measuring result indicates that a micro-cell whose business priority is higher than that of the macro-cell exists. According to the handoff scheme in the heterogeneous network by the method and apparatus, the cell capacity can be processed by the macro-cell and the micro-cell in a cooperative manner.

Description

technical field [0001] The present invention relates to the communication field, in particular to a switching method and device in a heterogeneous network. Background technique [0002] With the rapid growth of smart terminals and the commercialization of 4G (4th Generation, fourth-generation mobile communication technology) LTE (Long Term Evolution, long-term evolution) mobile communication technology, the rapid growth of mobile Internet economies such as mobile multimedia services and mobile shopping malls, the global Mobile data traffic will increase dozens of times, and the traffic growth of cell base stations is increasing year by year, while the frequency spectrum is exhausted year by year, and the processing capabilities of base stations are increasingly challenged. [0003] Due to the scarcity of spectrum resources and the difficulty of obtaining site resources, such as figure 1 It is impossible for the traditional Homogeneous Network (horizontal single-layer homoge...
