Embodiment 1

[0040] Embodiment 1. In this embodiment, the monitoring information is the load of the ZONE, where the load of the ZONE can be obtained through monitoring by the base station. see figure 2 , the method for performing ZONE switching by measuring the ZONE load includes the following steps:

[0041] S201: The base station continuously monitors the loads of various types of ZONEs;

[0042] S202: When the load of a certain type of ZONE is greater than the preset cut-out threshold, the terminal with the largest load in the type of ZONE is used as the terminal to be switched;

[0043] Among them, the load of a certain type of ZONE is related to the number of terminals in this type of ZONE. For each type of ZONE, the number of terminals that can be accommodated is different. For example, the number of terminals that can be accommodated by some subcarrier zones is less than that of all subcarrier zones. The number of terminals that can be accommodated. When a terminal enters a certai...

Embodiment 2

[0050] Embodiment 2. In this embodiment, the monitoring information is the signal quality of the terminal; wherein, the signal quality of the terminal can be obtained by the base station by measuring the uplink signal quality of the terminal after the terminal is connected to the network, or can be obtained by the terminal to The base station feeds back the downlink signal quality, so that the base station knows the signal quality of the terminal. see image 3 , the method for performing ZONE switching by measuring the signal quality of the terminal includes the following steps:

[0051] S301: Continuously measure the signal quality of the terminal;

[0052] S302: When the signal quality of a terminal reaches the cut-out threshold of the current ZONE, determine the terminal as the terminal to be switched;

[0053] S303: Measure the signal quality of the terminal to be switched in the target ZONE; if the signal quality of the terminal to be switched in the target ZONE reaches...

Embodiment 3

[0058] Embodiment 3. In this embodiment, the monitoring information is the link delay of the terminal; wherein, the link delay of the terminal can be obtained by the base station by actively measuring the link delay of the terminal after the terminal is connected to the network , the terminal can also report the link delay to the base station through a message, so that the base station can learn the link delay of the terminal. see Figure 4 , the method for performing ZONE switching by measuring the link delay of the terminal includes the following steps:

[0059] S401: Continuously measure the link delay of the terminal;

[0060] S402: When the link delay of a certain terminal reaches the cut-out threshold of the current ZONE, determine the terminal as the terminal to be switched;

[0061] S403: Measure the signal quality of the terminal to be switched in the target ZONE; if the signal quality of the terminal to be switched in the target ZONE reaches a preset cut-in thresho...

Abstract

The invention discloses a method for zone switching, which comprises the steps of: continually monitoring zones or terminals, and determining the terminal to be switched according to monitoring information; measuring the signal quality of the terminal to be switched under a target zone; and switching the terminal to be switched to the target zone if the signal quality of the terminal to be switched under the target zone achieves a preset cut-in threshold. The invention also discloses a device for zone switching. The embodiment of the invention ensures the signal quality of the terminal in thezone after the switching, and avoids the situation that the signal quality is poor and even the normal communication fails to be performed caused by the switching.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method and device for zone switching. Background technique [0002] The partial frequency reuse (Flexible Frequency Reuse, FFR) networking method can comprehensively use the characteristics of some subcarriers (PUSC) and all subcarriers (PUSC with all SC). All base stations use one frequency point, and the range near the center of the base station All subcarriers are used within the cell to improve the efficiency of spectrum utilization, and some subcarriers are used in the edge area far from the center of the base station to ensure network coverage; at the same time, users at the edge of the cell only occupy part of the spectrum to avoid inter-channel interference. In the same cell, it can be divided into different areas according to the service type used (that is, all subcarriers or some subcarriers). These areas are usually called ZONEs using a certain s...
