This is incorporated herein by reference.

Technical field

The present invention relates to the field of communications, and in particular, to a method for selecting a channel spectrum resource, a first device, a second device, and a channel spectrum resource selection system.

Background technique

With the widespread popularity of smart terminals, mobile data services continue to grow, and mobile operators' networks are under tremendous pressure. The deployment of small cells (Small Cell) and the addition of new frequency points are ways to increase wireless network data traffic. With its rich bandwidth resources (3400-3600MHz, LTE Band42/43), the 3.5GHz band has become a hot spot worldwide. In the United States, because it is difficult to clean up the main users in the 3.5GHz band, the Federal Communications Commission (FCC) started research in 2014 to use Spectral Access System (SAS) spectrum sharing. Using 3550-3700MHz total 150MHz spectrum resources, the SAS is based on the interference management system (Element Management System (EMS), Network Management System (NMS) or City Broadband Radio Service Device (CBSD) Select to allocate channel spectrum resources that can be used.

Here, the channel spectrum resources that can be used by the SAS are limited, and the operator cannot actively select the desired channel spectrum resources according to his own needs, and can only use the channel spectrum resources that the SAS has allocated. The operators here can be EMS, NMS, CBSD or third party service providers. In particular, for some special needs of operators, such as intra-frequency networking and in-band continuous carrier aggregation, the channel spectrum resources selected by SAS may not meet the needs of operators.

detailed description

The embodiment of the present invention provides a method for selecting a channel spectrum resource, a first device, and a second device, which are used to select information of a target channel from information of a currently available channel according to channel requirements. Meet the needs of operators.

The Spectrum Access System (SAS) is a centralized management center for 3.5 GHz spectrum. SAS directly or indirectly controls the Citizens Broadband Radio Service Device (CBSD) using the 3.5 GHz spectrum. As shown in FIG. 1 , a schematic diagram of an application scenario of a spectrum access system may include a SAS, a CBSD, a database, a primary user, an Environment Sensing Capability (ESC), a domain proxy (Domain Proxy), and a unit management system ( Other devices such as Element Management System, EMS). It should be noted that the number of CBSDs is not limited. Here is a brief description of the concepts that have emerged above:

SAS is mainly used to collect channel occupancy information of geographical locations; provide a list of available channels for geographic locations; CBSD authentication, registration, etc.;

CBSD mainly refers to devices that use the 3.5 GHz band in spectrum sharing mode;

Database, generally refers to the FCC database of the Federal Communications Commission (FCC) database, which is mainly used to store Priority Access Layer (PAL) users/devices and General Authorized Access (GAA). User/device information;

The main user mainly includes the existing main user information; the exclusive area information;

The ESC is mainly used to listen to the primary user signal; it is determined that the primary user reaches the affected area;

The domain agent is an intermediate management entity that selects the channel used for CBSD or transmits information to the EMS for calculation by the EMS;

The EMS can also be an NMS (Network Management System) network management system, which is an operator network management system. It mainly uses channel and power information for CBSD configuration.

The usage of the Layer 3 channel spectrum resources defined by SAS is as follows:

The user of the Incumbent Access (IA) has the highest priority channel spectrum resource usage right at the first layer, and the other priority access layer users and the general authorized access users cannot interfere with the primary user;

Priority Access (PA) users or Priority Access Layer (PAL) users. At the second level, the channel spectrum resource usage rights of one or more census tracts are obtained through auction, and channel spectrum resources are used. The priority is lower than that of the primary user but higher than that of the GAA user. The channel spectrum resources being used need to exit the spectrum occupation when the primary user arrives, and will not be interfered by the GAA user;

General Authorized Access (GAA) users, at the lowest level, have no interference protection. When an IA user or a PAL user needs to use channel spectrum resources, the GAA user needs to give up the channel spectrum resources being used.

The technical solution of the present invention is specifically described in the following embodiments. As shown in FIG. 2, an embodiment of a method for selecting a channel spectrum resource in an embodiment of the present invention includes:

201. The first device sends a spectrum query request to the second device, where the spectrum query request includes channel selection information.

The first device sends a spectrum query request to the second device, where the spectrum query request includes channel feedback information, where the channel feedback information is used to instruct the second device to feed back information about the currently available channel to the first device.

As an implementation manner, in this embodiment, before the first device sends the spectrum query request to the second device, the first device sends an authentication request (Authenticate Request) to the second device, where the authentication request may include the device identity and the user. The second device sends an authentication response (Authenticate Response) to the first device, and the first device sends a registration request (Register Request) to the second device, where the registration request may include the type, name, and geography of the device. The second device sends a registration response (Register Response) to the first device, and then the first device sends a spectrum inquiry request to the second device, where the spectrum query request includes channel feedback information and channel feedback information. And information for instructing the second device to feed back the currently available channel to the first device.

It should be noted that the first device herein may be the EMS or NMS of the operator mentioned above, or may be a CBSD or a base station eNB. If the operator or the enterprise does not deploy the EMS, the NMS, or the CBSD, the first device also It can be replaced by a domain proxy, which is not limited herein. The second device here may be the SAS mentioned above. In the embodiment of the present invention, the first device mainly acquires channel spectrum resources for the PAL user and the GAA user.

The second device receives the spectrum query request sent by the first device, and the spectrum query request includes channel feedback information, where the channel feedback information is used to instruct the second device to feed back information about the currently available channel to the first device.

In this embodiment, after the first device sends the spectrum query request to the second device, the second device receives the spectrum query request sent by the first device, where the spectrum query request includes channel feedback information, and the channel feedback information is used to indicate that the second device is The first device feeds back information of the currently available channel, and the first device selects information of the target channel from information of the currently available channel.

202. The second device determines information about a currently available channel according to the spectrum query request.

In the embodiment of the present invention, the second device determines the currently available channel information (Available Channels) according to the spectrum query request. Specifically, in an actual application, the second device may determine information about the currently available channel according to the spectrum query request, the currently available spectrum, the interference situation, and the geographic location. It should be noted that the reference condition that the second device determines the information of the currently available channel is not limited to the available spectrum, the interference, or the geographic location, and may include other reference conditions, which are not limited herein.

As an example, the Federal Communications Commission (FCC) began researching the use of SAS (Spectrum Access System) spectrum sharing in 2014 to use a total of 150 MHz spectrum resources of 3550-3700 MHz, here 150 MHz The spectrum resources are illustrated.

(3) The channel requirement includes the number of channels and the same channel number information. The same channel number information here means that the first device requests channel spectrum resources for several PAL users or GAA users at the same time, and these PAL users or GAA users require The selected channel numbers are the same; or, at the same time, several first devices request channel spectrum resources for the PAL user or the GAA user, and the first device requires that the selected channel numbers be the same.

Exemplarily, assuming that the first device requests channel spectrum resources for three PAL users, and that the channel numbers selected for the three PAL users are the same, the first device selects the same channel as the target channel. Or, at the same time, two first devices request channel spectrum resources for the GAA user, and request the target signals selected by the two first devices. The channel numbers of the channels are the same, then the two first devices select the same channel as the target channel.

It should be noted that the channel requirement herein may also include other information, and the corresponding target channel may be selected according to different channel requirements of the first device, thereby meeting the requirements of the operator.
