Embodiment 1

[0040] figure 2 It is a flow chart of the method in this embodiment. In this embodiment, the cells 1-3 are all LTE cells, and all have a working bandwidth of 10 MHz.

[0041] Step 101: Cells 1-3 need to be reconfigured, and each cell sends a respective reconfiguration request, and the reconfiguration request carries load conditions (respectively high, high, high) reflecting respective cells, average channel quality (respectively 4dB , 5dB, 6dB) reconfiguration trigger parameters;

[0042] Step 102: Ask the MME about information about users interacted by each cell in the initial context setup process (INITIAL CONTEXT SETUP), such as the quality of service level (QoS Class Identifier, QCI) information unit, the guaranteed bit rate (Guaranteed Bit rate) of the three cells Rate, GBR) (respectively 128kbit / s, 256kbit / s, 512kbit / s); the reconfiguration trigger judgment module determines to the MME the number of users who have not released the context (context) in each cell (respec...

Embodiment 2

[0051] image 3 It is a flow chart of the method in this embodiment. In this embodiment, the cells 1-3 are all LTE cells, and all have a working bandwidth of 10 MHz.

[0052] Step 201: Cells 1-3 need to be reconfigured, and each cell sends its own reconfiguration request;

[0053] In this embodiment, the load situation (respectively high, high, high) and average channel quality (respectively 4dB, 5dB, 6dB) of each cell are acquired through newly added signaling messages;

[0054] Step 202: Ask the MME for information about the user interacted in the initial context setup process (INITIAL CONTEXT SETUP), such as the QCI information unit, the GBR of the three cells (respectively 128kbit / s, 256kbit / s, 512kbit / s); Determine the number of users (80, 60, and 50 respectively) and user level information in each cell that have not released the context to the MME. The number of high-level (VIP) users in cell 1 is the largest, the number of VIP users in cell 2 is the second largest, and...

Embodiment 3

[0060] Figure 4 It is a logical structure diagram of the device of the present invention, and the device 300 includes: a transmission capability acquisition module 301, a transmission requirement acquisition module 302, and a reconfiguration trigger judgment module 303;

[0061] The transmission capability acquisition module 301 is configured to acquire parameters that can reflect the current transmission capability of the cell that requests reconfiguration; the parameters that reflect the current transmission capability of the cell that requests reconfiguration include at least one of the following: parameters that reflect load, parameters that reflect resource usage parameter.

[0062] Preferably, the transmission capability acquisition module 301 can obtain the current transmission capability of the cell reflecting the request for reconfiguration from the base station through a reconfiguration request message sent by each cell or a newly added signaling message or other ex...

Abstract

The invention discloses a reconfiguration trigger method and a reconfiguration trigger device for a reconfigurable wireless system, for solving the technical problem that an unreasonable reconfiguration trigger mechanism causes unreasonable resource allocation and lower system performance. According to the method, the resource coordination strategy among the cells asking for reconfiguration according to the relation between the parameters reflecting the present transmission capabilities of the cells asking for reconfiguration and parameters reflecting the basic transmission demands of the cells asking for reconfiguration is decided; the cells asking for reconfiguration, in which the present transmission capabilities are smaller than the basic transmission demands, are defined as priority reconfiguration cells; among the priority reconfiguration cells, the reconfiguration requests of cells containing more high-grade users are met preferentially; and after the reconfiguration requests of the priority reconfiguration cells are met, the rest resource is used for the reconfiguration of other cells asking for reconfiguration. By adopting the invention, the cell mischievous applications or non-must applications are avoided, and the accuracy and the resource allocation reasonableness of the cell reconfiguration are improved.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a reconfiguration triggering method and device for a reconfigurable wireless system. Background technique [0002] The scope of the reconfigurable wireless communication system discussed in the current agreement mainly focuses on how to coordinate and allocate system resources (including hardware resources and wireless resources) within a certain range when the system has a cell that is overloaded and needs to be reconfigured, so that the system performance Get the biggest boost and maximize resource utilization. The issue of the trigger mechanism was not discussed. [0003] When reconfiguration is triggered, each cell may apply for too many resources in order to improve the performance of the cell. Although this improves the experience of the users in the cell, it reduces the performance of the system. For example, the load of cell A is light, and the load of cel...
