Embodiment Construction

[0019] The specific embodiment of the present invention provides a method for allocating spectrum resources in a heterogeneous wireless network, the method is as follows figure 1 shown, including:

[0020] S11. After receiving the request from the unauthorized user, detect whether the common frequency band is idle, if so, proceed to step S12; otherwise proceed to S13-S15;

[0021] S12. Accept the request of the unlicensed user, and allocate the unlicensed user to a common frequency band;

[0022] S13. Detect whether the reserved frequency band is free, if so, proceed to S14; otherwise proceed to S15;

[0023] S14. Accept the request of the unlicensed user, and allocate the unlicensed user to the reserved frequency band;

[0024] S15. Reject the request of the unauthorized user.

[0025] In the method provided by the invention, the unlicensed users are assigned to the reserved frequency band under the condition that the common frequency band has no free channels, thereby ens...

Abstract

The invention provides a method and a device for allocating frequency spectrum resource in a heterogeneous wireless network, which belong to the field of network communication. The method comprises the following steps: after the network at a licensed frequency band receives the requests from unlicensed users, judging whether a common frequency band is idle, if so, receiving the requests from the unlicensed users, and allocating the unlicensed users to the common frequency band, otherwise, receiving the requests from the unlicensed users when a reserved frequency band is idle, and allocating the unlicensed users to the reserved frequency band, wherein the common frequency band provides service to licensed users and the unlicensed users, and the reserved frequency band specially provides service to the unlicensed users. The technical scheme provided by the specific embodiment of the invention has the advantages of ensuring the service quality of the unlicensed users when the licensed users appear.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for allocating frequency spectrum resources in a heterogeneous wireless network. Background technique [0002] In recent years, from 3G to WLAN, WiMAX, from UWB to ZigBee, from Bluetooth to DVB-H, the diversified development pattern of wireless communication has become increasingly obvious, and the complementary integration of various wireless network technologies has become the general trend. The rapid development of wireless communication not only puts forward higher requirements for the organic integration of heterogeneous networks, but also puts forward higher requirements for spectrum resources. The existing wireless spectrum allocation system is fixed spectrum allocation, which divides the spectrum into two parts: licensed frequency band (Licensed Frequency Band, LFB) and unlicensed frequency band (Unlicensed Frequency Band, UFB). Most of the spectrum ...
