Embodiment 1

[0055] figure 1 Is a flowchart of Embodiment 1 of the resource adaptation method of the present invention, such as figure 1 As shown, this embodiment includes:

[0056] Step S101: Acquire characteristic parameters of short-term spectrum resources, and execute step S103;

[0057] Step S103: Determine whether the current load of the communication cell exceeds the set threshold, if yes, perform step S105, otherwise continue to perform step S103;

[0058] Step S105: Obtain the service characteristics of the terminal that is carrying the service in the communication cell, select the terminal to be handed over, and execute step S107;

[0059] Step S107: According to the characteristic parameters of the short-term spectrum resource, the terminal to be handed over is adapted to the short-term spectrum resource matching its service characteristics.

[0060] In the resource adaptation method proposed in this embodiment, the matching of the service characteristics of the terminal and the spectrum ...

Embodiment 2

[0062] In this embodiment, in the scenario of a single communication cell, it is assumed that the communication cell itself has a long-term fixed allocation of frequencies. The base station and some terminals support the frequency reconfiguration function. When the load of the communication cell exceeds a certain threshold, the terminal obtains the detection spectrum through CR technology Resources, or lease spectrum resources through negotiation between networks to obtain short-term available spectrum resources, which can relieve system pressure, supplement system capacity, and realize dynamic allocation of spectrum resources and expansion of system capacity.

[0063] In this embodiment, leased spectrum resources and detection spectrum resources are used as short-term spectrum resources for illustration. The spectrum characteristics can be characterized by statistical feature parameters, and the main statistical feature parameters can include: availability, available time, and sta...

Embodiment 3

[0084] Figure 4 It is a schematic diagram of determining the load to be switched in the third embodiment of the resource adaptation method of the present invention. Such as Figure 4 Shown, where,

[0085] T: overload threshold load, that is, if the load exceeds the threshold, the system is in an overload state;

[0086] T’: Historical statistical experience sets the threshold load, under which the system is in the optimal performance state;

[0087] L: Current load, here can be characterized by bandwidth;

[0088] N: (L-T’) load capacity;

[0089] M: Switchable load capacity, comprehensively considering various information of the terminal, including terminal reconfiguration capability, moving speed, delay requirements, bandwidth requirements, etc., among all terminals, the terminal with low delay sensitivity requirements is preferred as the terminal to be switched . The so-called handover means that the user satisfies the most basic factors for terminal reconfiguration. In addition...

Abstract

The invention discloses a resource adapting method, a device and a system. The method comprises the following steps: acquiring characteristic parameters of a short-time frequency spectrum resource; when the current load of a communication cell exceeds the preset threshold, acquiring service characteristics of a terminal bearing a service in the communication cell, and selecting a terminal to be switched to; and according to the characteristic parameters of the short-time frequency spectrum resource, adapting the terminal to be switched to a short-time frequency spectrum resource matching the service characteristics of the terminal to be switched to. The invention considers the short-term availability of the short-time frequency spectrum resource when switching the frequency, and can adaptthe service to the frequency spectrum resource matching the frequency spectrum characteristics, thereby increasing the success ratio of switching and ensuring the QoS characteristic of the service. The invention can overcome the defects of failure to ensure that the service characteristics of the service borne by the terminal match the frequency characteristics of the switched frequency band whenswitching the terminal, failure to ensure the QoS characteristic of the switched service, and the like in the prior art.

Description

Technical field [0001] The present invention relates to the field of mobile communication, and in particular to a method, device and system for resource adaptation initiated by the network side. Background technique [0002] The radio communication spectrum is a precious and limited resource, which is uniformly allocated and authorized for use by the state. A frequency band is generally only used by one wireless communication system independently for a long time, and different wireless communication systems use different frequency bands and do not interfere with each other. With the rapid development of wireless communication, especially due to the recent significant increase in spectrum-based services and equipment, people's demand for spectrum resources is increasing, and spectrum resources are increasingly scarce. [0003] The spectrum resources of the current authorized system are fixedly allocated, and the system capacity is fixed and limited. As the number of terminals incre...
