Problems solved by technology

These spectrum sharing technologies have played a certain role, but because the sharing is either not flexible enough, or the sharing granularity is very limited, it is difficult to meet the demands of operators to maximize spectrum efficiency

Embodiment 1

[0068] The operator's spectrum resources are just enough to form a network and meet the minimum bandwidth requirements of each standard. Embodiment 1 mainly considers the most common FDD network of the mobile communication network: GSM, UMTS, and LTE coexist. The bandwidth of each carrier frequency in the GSM system is 200kHz, but GSM has certain frequency reuse requirements. For example, it needs to meet the frequency reuse degree of 4*3. If one carrier frequency per cell is satisfied, the total bandwidth resources required = each carrier frequency Bandwidth * frequency points = 200kHz * 12 = 2.4MHz; the system bandwidth of each carrier frequency of UMTS is 5MHz; LTE supports 1.4 / 3 / 5 / 10 / 15 / 20MHz, but the larger the system bandwidth, the more it can reflect the high spectral efficiency of the LTE system , usually the system bandwidth of the LTE network requires 5MHz or more. Therefore, the first embodiment of the present invention considers that the operator's total frequency...

Embodiment 2

[0180] In an embodiment of the present invention, the current most common FDD system is taken as an example to illustrate that a multi-standard system can be completely shared on the same spectrum resource, and other FDD systems such as CDMA and TDD systems such as TD-SCDMA systems can also be used in the first embodiment. The technology realizes the complete sharing of spectrum resources. Likewise, it is also common to future communication systems that are gradually emerging.

Embodiment 3

[0182] An embodiment of the present invention emphasizes the minimum requirement of an integrated GSM / UMTS / LTE system, complete spectrum sharing on 5MHz spectrum resources. When the spectrum resource of the operator exceeds 5 MHz, the technology in the embodiment of the present invention is also applicable. In addition, if the spectrum resources are sufficiently loose between multiple standard systems, part of the spectrum resources can be shared, making resource utilization more reasonable and providing users with better services.

[0183] The beneficial effect that the embodiment of the present invention has:

Abstract

The present invention relates to a spectrum resource allocation method and device for complete spectrum sharing, the method comprising: a base station acquires a network access request message sent by the terminal in real time, and the network access request message includes at least one of the following: The network standard supported by the terminal, the access service of the terminal, and the service quality QoS of the access service; the base station dynamically allocates spectrum resources to different network standards according to the network access request message; the The base station sends a first network standard access indication message to the terminal, so that the terminal accesses a service through a corresponding network standard according to the first network standard access indication message.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a spectrum resource allocation method and device for complete spectrum sharing. Background technique [0002] With the popularization of smart terminals, the Internet of Everything, and the rise of various mobile broadband (MBB) services, virtual reality (virtual reality, VR) / augmented reality (augmented reality, AR) services, mobile communication technology is developing rapidly. From 2G / 3G to 4G evolution, 5G deployment is also on the agenda. However, spectrum resources are always the most valuable resources for operators, especially the frequency bands used by current mobile systems have obvious advantages in propagation characteristics compared with the high frequency / ultra high frequency bands of 5G in the future, and will still be hot in the future 5G era. How to rationally utilize spectrum resources and maximize spectrum efficiency will...
